    An experiment was conducted to estimate the optimal dietary zinc (Zn) level of brown-egg laying hens fed a corn-soybean meal diet from 20 to 40 weeks of age. A total of 120 20-week-old Beijing Red commercial laying hens were randomly allotted by bodyweight to one of five treatments with six replicates of four birds each in a completely randomized design, and fed a Zn-unsupplemented corn-soybean meal basal diet containing 27.95 mg Zn/kg by analysis and the basal diets supplemented with 30, 60, 90, or 120 mg Zn/kg as Zn sulfate (reagent grade ZnSO 4 ·7H 2 O) for a duration of 20 weeks. Laying performance, egg quality, tissue Zn concentrations, and activities of serum alkaline phosphatase (AKP), and liver copper-Zn superoxide dismutase (CuZnSOD) were measured. Regression analyses were performed to estimate an optimal dietary Zn level whenever a significant quadratic response (P < 0.05) was observed. Tibia Zn concentration (P = 0.002) and serum AKP activity (P = 0.010) showed significant quadratic responses to dietary supplemental Zn levels. The estimates of dietary Zn requirements for brown-egg laying hens from 20 to 40 weeks of age were 71.95 and 64.63 mg/kg for tibia Zn concentration and serum AKP activity, respectively. The results from this study indicate that the tibia Zn might be a more suitable and reliable parameter for Zn requirement estimation, and the optimal dietary Zn level would be about 72 mg/kg for brown-egg laying hens fed a corn-soybean meal diet from 20 to 40 weeks of age.

    Dietary inclusion of antibiotics as growth promoters (AGPs) in poultry production has been applied for decades worldwide, but recently AGPs have been banned due to the negative consequences for health and food safety. Soybean oligosccharide (SOS) derived from soybean meal extract is one of natural compound without carrying-over the residue to product and is consumer’s health friendly. The purpose of the present study was to evaluate dietary inclusion of SOS on broiler meat quality. A total of 120 broilers of 7-day-old were allocated into 3 treatments with 4 replications (10 birds each) in completely randomized design. Treatments applied were D1: diet without SOS, D2: D1 plus 0.15% SOS, and D3: D1 plus 0.30% SOS. Intestinal lactic acid bacteria (LAB), protein digestibility, meat protein and fat depositions, and meat cholesterol were the parameters observed. Data were statistically tested using analysis of variance and Duncan test. Dietary SOS inclusion at 0.30% (D3) significantly (P<0.05) increased LAB population (7.21x104 cfu/g), protein digestibility (72.80%), and meat protein deposition (90.83 g/bird), but it decreased meat fat (8.27 g/bird) and meat cholesterol (37.28 mg/100 g). In conclusion, dietary SOS inclusion at 0.30% improves meat quality of broiler based on the increase in meat protein deposition with lower fat and cholesterol.

    Full Text Available Two feeding experiments have been conducted to test the different sources of soybean meal (local, India, USA and the partial substitution with peanut meal (10%, rapeseed meal (5% and fish meal (5% in the diet for broiler. The first feeding experiment was carried out on broiler starter for 4 weeks in wire cages . Twelve rations in factorial design (3 x 4 were conducted using 6 birds/cage and replicated 6 times . Birds fed India soybean meal had significantly less body weight (1,000 g than those fed local or USA soybean meals (1,037 and 1,023 g, respectively . Partial substitution with peanut, rapeseed or fish meal did not affect body weight, feed consumption or feed/gain ratio . The average consumption and feed/gain were 1,535 g and 1,569, respectively . In second experiment, one thousand five hundred broiler chicks were allocated in 6 dietary treatments in factorial design (3 x 2 . Factor one was different sources of soybean meal (local, India and USA and factor two was the inclusion of peanut meal at 0 and 10%. Birds were kept on litter system for 6 weeks . Each treatment used 5 replicates and 50 birds/replicate . The results show no effect of the treatment to any parameter measured . Body weight of bird fed local, India and USA soybean meal were 1,662, 1,641 and 1,669 g and feed/gain were 2 .043, 2 .051 and 2.035, respectively . Cost analysis indicates that ration uses local soybean meal gives a higher cost than those of India and USA soybean meals.

    This study evaluated the effect of fermentation on the nutritional quality of food-grade soybeans and feed-grade soybean meals. Soybeans and soybean meals were fermented by Aspergillus oryzae GB-107 in a bed-packed solid fermentor for 48 hours. After fermentation, their nutrient contents as well as trypsin inhibitor were measured and compared with those of raw soybeans and soybean meals. Proteins were extracted from fermented and non-fermented soybeans and soybean meals, and the peptide characteristics were evaluated after electrophoresis. Fermented soybeans and fermented soybean meals contained 10% more (P 60 kDa) (P 60 kDa), whereas 22.1% of peptides in soybean meal were large-size (>60 kDa). Collectively, fermentation increased protein content, eliminated trypsin inhibitors, and reduced peptide size in soybeans and soybean meals. These effects of fermentation might make soy foods more useful in human diets as a functional food and benefit livestock as a novel feed ingredient.

    Full Text Available Two experiments were conducted to evaluate the effect of replacing soybean meal with xylose-treated soybean meal (soypass meal; SPM on performance of nursing Awassi ewes and fattening lambs. In Experiment 1, lasting for eight weeks, 39 Awassi ewes and their lambs were randomly assigned to three diets. Diets were formulated by replacing soybean meal from the basal diet (CON-SBM; n=13 with 50% (50% SPM; n=13 and 100% (100% SPM; n=13 SPM. Initial and final weights of the ewes were not different (P>0.55 among diets. Total gain and average daily gain (ADG of lambs were similar (P=0.44 among diets. Ewes fed the CON-SBM diet tended (P0.38 in milk component percentages among diets were observed. In Experiment 2, lasting for 63 days, twenty weaned lambs were used to determine the effects of replacing soybean meal with SPM on growth performance. Diets were either soybean meal (SBM; n=10 or SPM (SPM; n=10. Nutrient intake and digestibility were not different between diets. However, rumen undegradable protein intake was greater (P0.05 between the diets. Results suggest that replacement of soybean meal with soypass meal is not likely to produce any production benefits in nursing Awassi ewes and fattening lambs except for the slight improvement of milk yield.

    Full Text Available Prebiotics have successfully been used to prevent infectious diseases in aquaculture and there is an increasing amount of literature that suggests that these products can also improve alternative protein utilization and digestion. Therefore, the objective of this study was to examine whether prebiotic supplementation increased the growth efficiency, intestinal health and disease resistance of cutthroat trout fed a high level of dietary soybean meal. To achieve this objective, juvenile Westslope cutthroat trout (Oncorhynchus clarkii lewisi were fed a practical type formulation with 0 or 30% dietary soybean meal with or without the commercial prebiotic (Grobiotic-A prior to experimental exposure to Flavobacterium psychrophilum. Juvenile Westslope cutthroat trout (initial weight 7.8 g/fish ± standard deviation of 0.5 g were stocked at 30 fish/tank in 75 L tanks with six replicate tanks per diet and fed their respective diets for 20 weeks. Final weights of Westslope cutthroat trout were affected by neither dietary soybean meal inclusion level (P=0.9582 nor prebiotic inclusion (P=0.9348 and no interaction was observed (P=0.1242. Feed conversion ratios were similarly not affected by soybean meal level (P=0.4895, prebiotic inclusion (P=0.3258 or their interaction (P=0.1478.

Feeding dietary soybean meal level at 30% increased mortality of F.psychrophilum cohabitation challenged Westslope cutthroat trout (P=0.0345 while prebiotic inclusion tended to decrease mortality (P=0.0671. These results indicate that subclinical alterations in intestinal inflammation levels due to high dietary inclusion levels of soybean meal could predispose Westslope cutthroat trout to F.psychrophilum infection.

  12. Effect of microalgae on intestinal inflammation triggered by soybean meal and bacterial infection in zebrafish.

    Directory of Open Access Journals (Sweden)

    Karina Bravo-Tello

    Full Text Available Soybean meal has been used in many commercial diets for farm fish; despite this component inducing intestinal inflammation. On the other hand, microalgae have increasingly been used as dietary supplements in fish feed. Nevertheless, the vast quantity of microalgae species means that many remain under- or unstudied, thus limiting wide scale commercial application. In this work, we evaluated the effects to zebrafish (Danio rerio of including Tetraselmis sp (Ts; Phaeodactylum tricornutum (Pt; Chlorella sp (Ch; Nannochloropsis oculata (No; or Nannochloropsis gaditana (Ng as additives in a soybean meal-based diet on intestinal inflammation and survival after Edwardsiella tarda infection. In larvae fed a soybean meal diet supplemented with Ts, Pt, Ch, or Ng, the quantity of neutrophils present in the intestine drastically decreased as compared to larvae fed only the soybean meal diet. Likewise, Ts or Ch supplements in soybean meal or fishmeal increased zebrafish survival by more than 20% after being challenged. In the case of Ts, the observed effect correlated with an increased number of neutrophils present at the infection site. These results suggest that the inclusion of Ts or Ch in fish diets could allow the use of SBM and at the same time improve performance against pathogen.

    Full Text Available The present study investigated the effects of the inclusion of three oilseed by-products (soybean, copra and palm kernel meals on some physical characteristics of pelletized feeds as well as on voluntary feed intake and faecal matter production by the Nile tilapia, Oreochromis niloticus. The dietary inclusion of soybean meal resulted in a significantly higher feed bulk density relative to the fishmeal control diet. The inclusions of copra and palm kernel meals, however, resulted in lower feed bulk densities. Sinking rates, water stabilities and nutrient retention efficiencies of feed pellets were directly related to feed bulk densities. The soybean meal diet had the fastest sinking velocities, greatest water stability and highest nutrient retention rates. The dietary inclusion of soybean meal, however, significantly impaired feed intake compared to the other three diets. Mean daily feed intakes of the control, palm kernel meal and copra meal diets corresponded to 28.88, 27.01 and 28.31 g during the experimental period and varied significantly from the mean daily intake of the soybean meal diet which corresponded to 20.01 g. Faecal matter production (g dry mass kg−1 ingested feed was significantly higher in the tilapia groups fed the copra and palm kernel meals. The results obtained from this study show that 30% inclusions of unrefined forms of copra and palm kernel meal in Nile tilapia diets is possible, without adversely affecting feed intake or pellet nutrient losses prior to ingestion.

    This study was conducted to investigate and compare the effect of dietary probiotic mixture (PM) and organic acid (OA) mixture with fermented soybean meal (FSBM) on performance, crop, and ceca microbiota, small intestine morphology, and serum lipid profile in Japanese quails. A total of 800 day-old Japanese quails was randomly allotted to 5 treatments with 8 replicate pens of 20 birds each, for 35 days. The experimental diets consisted of a control corn-soybean meal diet and 4 test diets: 1) control diet + 0.1% PM; 2) control diet + 0.2% OA mixture; 3) control diet + the combination of both PM and OA; and 4) an additives-free diet in which the soybean meal in the control diet was replaced with FSBM. The results indicated that in starter and the entire rearing periods, FSBM, PM, and PM+OA diets had significantly lower FCR compared to control or OA diets (P < 0.05). Birds in the FSBM group gained higher weight than control and OA birds (P < 0.05; 1 to 35 d). At d 21 and 35, birds fed the control diet showed significantly lower numbers of lactic acid bacteria in the crop, while coliforms were higher in the cecal content compared to the other diets (P < 0.05). At d 21, the villus height and villus height to crypt depth ratio in the duodenum and jejunum of birds fed PM, PM+OA, and FSBM diets were greater than in other treatments (P < 0.05). The serum concentrations of cholesterol and low-density lipoprotein cholesterol of birds fed PM, PM+OA, and FSBM diets were significantly lower than birds in control and AO groups (P < 0.05). The results obtained herein suggest that FSBM exhibits probiotic properties and, when used in substitution of SBM in Japanese quail diet, can improve growth performance, balance of desirable gastrointestinal microbiota in crop and ceca, small intestinal morphology, and serum lipid profile-likewise, a probiotic supplement.

    The present study was conducted to determine the change of digestive physiology in sea cucumber Apostichopus japonicus (Selenka) induced by corn kernels meal and soybean meal in diets. Four experimental diets were tested, in which Sargassum thunbergii was proportionally replaced by the mixture of corn kernels meal and soybean meal. The growth performance, body composition and intestinal digestive enzyme activities in A. japonicus fed these 4 diets were examined. Results showed that the sea cucumber exhibited the maximum growth rate when 20% of S. thunbergii in the diet was replaced by corn kernels meal and soybean meal, while 40% of S. thunbergii in the diet can be replaced by the mixture of corn kernels meal and soybean meal without adversely affecting growth performance of A. japonicus. The activities of intestinal trypsin and amylase in A. japonicus can be significantly altered by corn kernels meal and soybean meal in diets. Trypsin activity in the intestine of A. japonicus significantly increased in the treatment groups compared to the control, suggesting that the supplement of corn kernels meal and soybean meal in the diets might increase the intestinal trypsin activity of A. japonicus. However, amylase activity in the intestine of A. japonicus remarkably decreased with the increasing replacement level of S. thunbergii by the mixture of corn kernels meal and soybean meal, suggesting that supplement of corn kernels meal and soybean meal in the diets might decrease the intestinal amylase activity of A. japonicus.

    Full Text Available ABSTRACT Two experiments were done to evaluate the effect of increasing levels of dietary digestible methionine (Met and Met:cysteine (Met:Cys ratio on the productivity of Hy-Line W-36 laying hens fed sorghum- and soybean meal-based diets. In Exp. 1, 160 hens from 68 to 75 weeks of age were assigned to four dietary levels of digestible Met (0.20 0.24, 0.28 and 0.32%. The digestible total sulfur amino acids:Lysine (TSAA:Lys ratios were: 62, 68, 76 and 84%. In Exp. 2, 192 hens from 76-83 weeks of age were assigned to four dietary digestible Met:Cys ratios (160, 116.7, 85.7 and 62.5%. The digestible TSAA:Lys ratio was kept constant across diets (80%. Results were subjected to ANOVA and linear regression analyses. In Exp. 1, optimal egg production, egg mass, and feed efficiency responses were observed at 0.30 and 0.50% of dietary digestible Met and TSAA, respectively (quadratic effect, p<0.05. Live performance was maximized with digestible Met and TSAA in takes of 288 and 478 mg/hen/d, respectively. In Exp. 2, optimal egg production and feed efficiency responses were observed at 151 and 150% of dietary digestible Met:Cys ratios, respectively (quadratic effect, p<0.05. The digestible Met, Cys and TSAA intake to maximize egg production and feed efficiency were 313, 207 and 510 mg/hen/d, respectively. The requirements for sulfur AA in Hy-Line W-36 hens from 68 to 83 weeks of age fed sorghum- and soybean meal-based diets fell inside the range of the requirements previously estimated in hens fed corn-soybean meal based diets.

    2018-01-01

    The nutritional value of raw Jack bean meal ( Canavalia ensiformis ) as a partial substitute for soybeans meal was investigated in this study. Preliminary investigation on nutrient composition revealed that lysine, histidine, and phenylalanine were significantly higher in C .  ensiformis seed meal compared to soybean meal. However, crude protein and other essential amino acids were significantly lower. Feeding trial was then conducted to investigate the effect of replacing about 40% soybeans meal (at 58.8% inclusion) with C .  ensiformis in the diet of Clarias gariepinus . The result obtained after 56 days revealed that fingerlings could tolerate up to 20% replacement without significant effect on growth and nutrient utilization. Beyond this, growth was significantly reduced. Survivals of the fish also follow a similar trend as stated above. It was concluded that dietary inclusion of raw C .  ensiform meal should not be beyond 11% (or 20% replacement for soybeans meal included at 58.8%) in the diet of C .  gariepinus .

    Full Text Available Abstract Little information is available about the nutritive value of expanded soybean meal, which is produced by expansion of soybeans prior to solvent extraction of the oil. During processing, expanded soybean meal is subjected to additional heat, which might increase the concentration of ruminally undegraded protein. Processing of soybeans with heat during oil extraction could affect lysine availability by increasing ruminally undegraded protein or by impairing intestinal digestion. Our objective was to compare solvent and expanded soybeans with regard to chemical composition and nutritive value for dairy cattle. Samples of expanded soybean meal (n = 14 and solvent-extracted soybean meal (n = 5 were obtained from People's Republic of China to study effects of the expansion process on nutritive value for dairy cattle. Solvent-extracted soybean meal (n = 2 and mechanically extracted (heated soybean meal (n = 2 from the United States served as references for comparison. Samples were analyzed for crude fat, long-chain fatty acids, crude protein, amino acids, chemically available lysine, in situ ruminal protein degradation, and in vitro intestinal digestibility. No differences were found between solvent-extracted soybean meals from China and expanded soybean meals from China for crude fat, crude protein, amino acids, or chemically available lysine. In situ disappearance of nitrogen, ruminally undegraded protein content, and in vitro intestinal digestion of the ruminally undegraded protein were generally similar between solvent-extracted soybean meals made in China and expanded soybean meals made in China; variation among soybean meals was small. Results indicate that the additional heat from the expansion process was not great enough to affect the nutritive value of soybean meal protein for ruminants. Although expansion may improve the oil extraction process, the impact on the resulting soybean meal is minimal and does not require consideration

    Full Text Available The objective this work was to evaluate the technical and economic viability of the substitution level of soybean meal by babassu meal in rations to broiler from 22 to 42 days old. It was used 80 male broiler chicks at one day of age, distributed into complete random designs with four treatments (0, 10, 20 e 30% substituition of soybean meal by babassu meal and five repetitions of four broilers each. Were evaluated the performance (weight dain, feed intake and feed conversion, carcass and cuts, organ biometry, feed cost per kilogram body weight and gross margin. To verify the relationship of cost of replacing soybean meal with pie babassu, inequalities were established. The substitution level of soybean meal by babassu meal had no influence (P>0,05 any of the performance characteristics, wich showed the technical viability of substituting up to 30%. Similarly, there was no affect on carcass yield, cuts weight and organ biometry. The cust less with feed per kg for chicken produced and the higher gross margin were obtained from chickens fed diets with 0% babassu meal. The increased of substitution level soybean meal by babassu meal in ration for broilers from 22 to 42 days old proved unviable economically, however, the inequalities produced can be useful in practical situations.

    Full Text Available Feeding experiments were conducted to evaluate the effects of replacing fishmeal with soybean meal in diet on growth of humpback grouper. Fifteen cages of 1 x 1 x 1.2 m3 each stocked with 16 humpback grouper juveniles (61.3 ± 0.4 g/pc were set up randomly in seawater. Fish were fed to satiation twice daily for 112 days. The control diet contained 61.9% fishmeal (63.34% crude protein. Four isonitrogenous (48% crude protein and isocaloric (4.7 kcal/g feed diets supplemented with commercial phytase “Rhonozyme-P” at 0.075% were formulated to contain different levels (8%, 16%, 24%, and 32% soybean meal (43.65% crude protein as a partial replacement for fishmeal. These diets contained total phosphorus levels between 3.6—4.5 (±0.4 % and 0.7—1.5 (±0.04 % available phosphorus. Replacement of fishmeal with soybean meal (8 to 32% replacement was not significantly different (P>0.05 to the control diet on daily growth rate (DGR, food conversion ratio (FCR, protein efficiency ratio (PER, and daily food consumption (DFC. However, the dietary levels of soybean meal significantly affected (P<0.05 whole body protein and phosphorus retention (Table 1. These data suggest that addition of phytase in diets could improve protein and phosphorus availability and reduce nitrogen and phosphorus loading in the environment. Phytase can therefore play an important role in formulating eco-friendly feed for humpback grouper. Based on P loading, supplementation of phytase enable up to 24% fishmeal replacement with soybean meal.

    Full Text Available Sixty male broiler chickens was used to investigate the effects of dietary soybean meal (SBM with soy-milk waste (SMW substitution using growth performance, protein-energy efficiency ratio, and physical meat quality as response criteria. The birds were given control diet (SMW-0, or a control diets with 5% (SMW-1, 10% (SMW-2, and 15% (SMW-3 soy-milk waste substitutions. Each treatment was replicate 3 times, with 5 birds per replication. The obtained data were subjected to Oneway arrangement of ANOVA, and continued subsequently with Duncan’s new Multiple Range Test. Results showed that substituting SBM with SMW did not influence protein and energy consumption, as well as feed consumption and energy efficiency ratio. However, dietary substitution with 10% SMW improved (P<0.05 protein efficiency ratio, body weight gain, and slaughter weight, resulting in lower (P<0.05 feed conversion ratio. The meat pH, water holding capacity, cooking loss, and tenderness values did not influence by 5-15% SMW substitution.

    The high cost of commercial supplements necessitates evaluation of alternatives for ruminant livestock fed poor quality warm-season grasses. This study determined how supplementing bahiagrass haylage (Paspalum notatum Flügge cv. Tifton 9) with soybean [Glycine max (L.) Merr.] meal or warm-season legume haylages affected the performance of lambs. Forty-two Dorper x Katadhin lambs (27.5 +/- 5 kg) were fed for ad libitum intake of bahiagrass haylage (67.8% NDF, 9.6% CP) alone (control) or supplemented with soybean meal (18.8% NDF, 51.4% CP) or haylages of annual peanut [Arachis hypogaea (L.) cv. Florida MDR98; 39.6% NDF, 18.7% CP], cowpea [Vigna unguiculata (L.) Walp. cv. Iron clay; 44.1% NDF, 16.0% CP], perennial peanut (Arachis glabrata Benth. cv. Florigraze; 40.0% NDF, 15.8% CP), or pigeonpea [Cajanus cajan (L.) Millsp. cv. GA-2; 65.0% NDF, 13.7% CP]. Haylages were harvested at the optimal maturity for maximizing yield and nutritive value, wilted to 45% DM, baled, wrapped in polyethylene plastic, and ensiled for 180 d. Legumes were fed at 50% of the dietary DM, and soybean meal was fed at 8% of the dietary DM to match the average CP concentration (12.8%) of legume haylage-supplemented diets. Lambs were fed each diet for a 14-d adaptation period and a 7-d data collection period. Each diet was fed to 7 lambs in period 1 and 4 lambs in period 2. Pigeonpea haylage supplementation decreased (P haylages increased (P haylage, all supplements increased (P haylage supplementation, but unaffected (P = 0.05) by other supplements. Efficiency of microbial protein synthesis was unaffected (P = 0.05) by diet. Ruminal ammonia concentration was increased (P = 0.01) by all supplements, but only soybean meal and annual peanut haylage increased (P haylages are promising protein supplements for growing lambs.

    Full Text Available Abstract Different levels of dietary soybean meal (SBM as a fish meal (FM replacer, with and without amino acid supplementation, for whiteleg shrimp, Litopenaeus vannamei reared in the biofloc system was examined in eight weeks of feeding trial. Eight experimental diets consisted of a basal diet with 0% FM replacement by SBM provided in clear sea water without biofloc system (S0SW, four diets replacing FM at 0% (S0, 33% (S33, 67% (S67 and 100% (S100 by SBM, and three diets replacing FM at 33% (S33A, 67% (S67A and 100% (S100A by SBM supplemented with amino acids (methionine and lysine in the seawater biofloc system. Results of water quality analyses showed significantly lower total suspended solids and nitrate for S0SW group than all other treatments. Diets S0 and S33A resulted in higher weight gain and specific growth rate among all groups, with no significant differences with S33 group. In addition, whole-body protein and amino acid compositions of shrimp fed S0SW were lower than most biofloc groups. Haemolymph parameters showed significant differences in total protein, cholesterol and triglyceride between groups S0 and S0SW. Also, superoxide dismutase activity showed a decreasing trend with increasing replacement level. In conclusion, based on these results, SBM could replace up to 33% of FM with or without amino acid supplementation in juvenile whiteleg shrimp diets reared in the biofloc system.

    Full Text Available The objective of this study was to evaluate the effect of substituting soybean meal for cottonseed meal in multiple supplements on the nutritional characteristics and performance of beef heifers in their postweaning phase on Brachiaria decumbens pastures during the dry season. Twenty-four Nellore beef heifers (average initial age and weight of 8 mo and 210±6 kg, respectively were used. The design was completely randomized, with four treatments and six replicates. Supplements contained approximately 30% crude protein (CP and a progressive substitution of soybean meal for cottonseed meal (0, 50 and 100%. The control animals received only a mineral mixture ad libitum, and those on the other treatments received supplementation at 1.0 kg/animal/day. No differences were found in ADG between supplemented and control animals (P>0.10. Supplementation increased crude protein (CP intake only (P<0.10. The level of substitution of soybean meal for cottonseed meal did not affect (P>0.10 the intake of supplemented animals. Supplementation elevated the apparent digestibility coefficients (P<0.10 of OM, CP, NFC and TDN, but not EE or NDFap (P>0.10. A positive linear effect (P<0.10 of the level of substitution of soybean meal for cottonseed cake was observed on the digestibility of OM, NFC and TDN. Supplementation and the level of substitution had an effect (P<0.10 on the serum urea nitrogen and urine urea nitrogen contents. Supplementation or substitution level had no effect on the flow of microbial nitrogen to the intestine (MICN or efficiency of microbial protein synthesis (EMPS (P>0.10. Substitution caused a decreasing linear effect (P<0.10 on microbial nitrogen/nitrogen intake ratio (MICNR. In conclusion, substitution of soybean meal for cottonseed meal in multiple supplements during the dry season does not impair the productive performance of beef heifers.

    A 90-day sub chronic toxicity study was conducted in rats to evaluate the safety of genetically modified DAS-444Ø6-6 soybeans expressing herbicide tolerant proteins when compared with its conventional comparators (non-transgenic near isoline control soybean and three commercially available non-transgenic line control soybeans). Rats were given diets formulated with either 10% or 20% w/w of soybean meal and 1% or 2% hulls of DAS-444Ø6-6 soybean with an equivalent amount of hulls from an isoline non-transgenic control soybean for at least 90 days. In addition, three separate 20% w/w non-transgenic commercially available soybean varieties were also given to groups of rats to serve as reference controls. Animals were evaluated by cage-side and hand-held detailed clinical observations, ophthalmic examinations, body weights/body weight gains, feed consumption, hematology, prothrombin time, urinalysis, clinical chemistry, selected organ weights, and gross and histopathologic examinations. Under the conditions of this study, the genetically modified DAS-444Ø6-6 diets did not cause any treatment-related effects in rats following 90 days of dietary administration as compared with rats fed diets with soybean of isoline control or commercial reference controls and are considered equivalent to the diets prepared from conventional comparators.

    Dried distillers grain with solubles (DDGS) is an alternative source of feed protein for dairy cows. Previous studies found that DDGS, based on grains other than corn, can substitute for soybean meal and canola cake as a dietary protein source without reducing milk production or quality....... As societal concerns exist, and in many areas strict regulation, regarding nitrogen excretion from dairy cows, the dairy industry has focused on reducing dietary protein level and nitrogen excretion. In the present study, we investigated the use of DDGS as a protein source, at a marginally low dietary crude...... protein (CP) levels, in a grass-clover and corn silage-based ration. The experiment involved 24 Holstein cows and 2 protein sources (DDGS or soybean-canola mixture) fed at 2 levels of CP (14 or 16%) in a 4 × 4 Latin square design. The aim of this study was to evaluate the effect of both protein source...

    Full Text Available Commom protein sources for poultry, fish meal and soybean meal, were ground to obtain reduced particle size. The particle was then dissolved in distilled water (1 : 4 w/v, and added with 2 mL virgin coconut oil for every 500 mL solution prior to ultrasound transducer (ultrasonic bath treatment to obtain protein microparticle. Reducing particle size is one possible way to increase protein utilization.180 birds were used for forced feeding and 10 other birds were plotted for endogenous correction, when they were one month and a half old. Microparticle protein of both ingredients were tested separately in either mash or pelleted forms and compared to intact protein. Completely randomized design with 3 treatments (intact, mash, and pellet and 6 replications (10 bidrs each was arranged for the respective ingredient. Protein and essential amino acid digestibilities, and calcium retention were the parameters measured. Analysis of variance continued to Duncan test were applied to statistically evaluate the data. Pelleted microparticle protein of fish meal and soybean meal, respectively, resulted in significantly (P<0.05 highest protein and amino acids digestibilities, and Ca retention although lower disgestibility of fewer amino acids was found in mash form. In conclusion, pelleted form of microparticle protein of either fish meal or soybean meal improve protein and mostly amino acids digestibilities, and calcium retention in broiler.

    Conversion of biomass feedstock to chemicals and fuels has attracted increasing attention recently. Soybean meal, containing significant quantities of carbohydrates, is an inexpensive renewable feedstock. Glucose, galactose, and fructose can be obtained by enzymatic hydrolysis of soluble carbohydrates of soybean meal. Free fatty acids (FFAs) are valuable molecules that can be used as precursors for the production of fuels and other value-added chemicals. In this study, free fatty acids were produced by mutant Escherichia coli strains with plasmid pXZ18Z (carrying acyl-ACP thioesterase (TE) and (3R)-hydroxyacyl-ACP dehydratase) using individual sugars, sugar mixtures, and enzymatic hydrolyzed soybean meal extract. For individual sugar fermentations, strain ML211 (MG1655 fadD(-) fabR(-) )/pXZ18Z showed the best performance, which produced 4.22, 3.79, 3.49 g/L free fatty acids on glucose, fructose, and galactose, respectively. While the strain ML211/pXZ18Z performed the best with individual sugars, however, for sugar mixture fermentation, the triple mutant strain XZK211 (MG1655 fadD(-) fabR(-) ptsG(-) )/pXZ18Z with an additional deletion of ptsG encoding the glucose-specific transporter, functioned the best due to relieved catabolite repression. This strain produced approximately 3.18 g/L of fatty acids with a yield of 0.22 g fatty acids/g total sugar. Maximum free fatty acids production of 2.78 g/L with a high yield of 0.21 g/g was achieved using soybean meal extract hydrolysate. The results suggested that soybean meal carbohydrates after enzymatic treatment could serve as an inexpensive feedstock for the efficient production of free fatty acids. © 2015 Wiley Periodicals, Inc.

    It seems that faba bean (FB) seeds could be a good protein-energy component in animal feed, but the presence of anti-nutritional substances limits their use as a substitute of soybean meal. The aim of the study was to examine the influence of different concentrations of raw, low-tannin, FB seeds on the gut-bone axis in Ross 308 broilers. One-day old chickens were randomly subjected to one of the 3 dietary treatments: the control group was fed standard diet based on soybean meal and without FB seeds, and two groups were fed 8%/15% and 16%/22% of raw low-tannin FB seeds in the starter and grower, respectively. On the 35th day, hematological and serum biochemical analyses as well histomorphometry of the small intestine and liver tissue and bone mechanical tests were performed. The diet type had no effect on the body weight gain and feed conversion ratio. However, the basal intestinal structures were significantly reduced in birds fed the lower concentration of FB. The enlargement of nerve plexuses was dependent on the concentration used in the diet and, additionally, on the kind of plexus and location in the intestinal tract. The liver was characterized by an increase in non-hepatocytes. There was no influence of the low-tannin FB seeds on most of the analyzed serum parameters in the 35-day-old broiler chickens, except the decreased concentration of total cholesterol and Ca in both experimental groups, triglycerides in group I, and P and uric acid in group II. Furthermore, the increasing concentration of the dietary low-tannin FB did not influence the activities of AspAT (except the group fed the higher amount of FB), ALAT, and LDH. The broiler chickens had no visible leg lesions and no problem in the locomotor function, but the tibiae were lighter mainly in birds fed the higher concentration of FB seeds. Geometric analysis revealed reduction of the cross section area and wall thickness, indicating a decline in the bone midshaft, which influenced the densitometric

    Full Text Available The feasibility of carob seed germ meal (CSGM as a soybean meal (SBM replacement in the diet of red tilapia hybrid was evaluated in an 8-week feeding trial. Five isonitrogenous and isocaloric diets with increasing CSGM (0, 10, 20, 30 and 40%, at the expense of SBM, were fed to triplicated groups of tilapia fingerlings. Their growth, feeding efficiency, whole body proximate composition, selected plasma biochemical parameters, and liver and gut histopathology were assessed. The survival and growth of red tilapia were unaffected by the dietary CSGM inclusion up to 30%. Growth and feeding efficiencies were significantly reduced at 40% CSGM inclusion. Hematocrit and body crude lipid were significantly lower (p < 0.05 in fish fed 30–40% CSGM while plasma ALT and protein were significantly higher compared to the control (0% CSGM. In addition, some instances of lipofuscin and cellular degradation were shown in liver while morphological changes were observed in fish fed 30 and 40% CSGM. Some of these included a 60% and 34% reduction in goblet cell prevalence and villi length, respectively, as well as a thickening of the intestinal mucosal and submucosa layers of 51 and 27%, respectively as dietary CSGM increased from 0 to 40%, that was likely due to increased anti-nutritional factors. In conclusion, a dietary inclusion of only up to 20% untreated CSGM was recommended for red hybrid tilapia.

    Full Text Available The effects of the replacement of bread yeast by soybean meal in diets for Rhamdia quelen larvae on growth, survival, and intestinal morphology were analysed. Larvae were fed for 20 days with five diets: a control diet formulated with 57% of bread yeast, and other four diets in which soybean meal at concentrations of 14.25, 28.5, 42.75 and 57% was added to obtain 25, 50, 75 and 100% of bread yeast replacement. Growth and survival parameters were negatively affected by dietary soybean meal inclusion. Larvae fed control diet showed significantly higher mean weight, specific growth rate, final biomass, and survival rate than larvae from other treatments. Enterocyte height and fold width of the posterior intestine showed highest values in the control group, and an inverse linear relationship with the level of dietary soybean meal inclusion was observed, however, in the anterior intestine the morphology parameters were not affected by the diet. These results indicate that inclusion of soybean meal in diets for R. quelen larvae negatively affects growth and survival, as well as the capacity for digestion and absorption of nutrients, mainly in the posterior intestine.Neste estudo, foi analisado o efeito da substituição de levedura de pão por farelo de soja em dietas para larvas de Rhamdia quelen no crescimento, sobrevivência e morfologia intestinal.

    Broiler chickens are a fast growing monogastric animal commonly used to evaluate the equivalence between transgenic and non-transgenic grains as part of the human safety assessment process. While commonly viewed like other livestock feeding trials, such studies are performed with transgenic crops with input traits (that are not designed to improve nutrition) to aid regulatory authorities in evaluating safety. Studies of this type are actually more similar to toxicology studies in purpose, with sensitive endpoints like growth used to detect metabolic perturbations. DAS-68416-4 soybean expresses the aryloxyalkanoate dioxygenase-12 (AAD-12) enzyme which inactivates 2,4-diclorophenoxyacetic acid (2,4-D) and provides DAS-68416-4 soybeans tolerance to this herbicide. DAS-68416-4 also expresses the phosphinothricin acetyltransferase (PAT) enzyme from Streptomyces viridochromogenes which confers tolerance to glufosinate-ammonium herbicides. A 6-week broiler study was conducted with diets containing toasted DAS-68416-4 soybean meal (40, 36, and 32% in starter, grower and finisher diets, respectively) to evaluate nutritional wholesomeness and safety compared with conventional comparators. Toasting soybean meal is required to inactivate endogenous antinutrients making soybean suitable for consumption by monogastric animals like broiler chickens. Toasting was found to denature both the AAD-12 and PAT proteins rendering them non-detectable by enzyme linked immunosorbent assays. Broiler growth and performance parameters were measured over a 6-week period of exposure to diets containing different sources of toasted soybean meal, and results indicate that DAS-68416-4 soybean is nutritionally equivalent to non-transgenic soybean.

    Full Text Available The main objective of this experimental study was to determine how diets containing lupin meal affect the performance indicators, carcass value, and chemical composition of breast and thigh muscles in broiler chickens. The diets tested in experimental groups E1 and E2 differed as follows: in group E1, one third of nitrogen-containing substances (NSs from extracted soybean meal was replaced with NSs from lupin meal; in group E2, two thirds were replaced compared to the control group. The replacement of soybean meal with lupin meal in experimental diets failed to produce any significant effect on the average live weight of chickens on Day 42 of the fattening period compared to the control group. The replacement of soybean meal with lupin meal resulted in decreased average weight of carcass and breast muscles and in decreased yield of breast muscles. Differences between the control group (C and group E2 were significant (P ⪬ 0.01. Chickens in group E2 also showed a significant increase (P ⪬ 0.01 in the yield of the heart and stomach compared to the control group. The differences in weight and yield of thigh muscles between the control group and the experimental groups (E1 and E2 were not significantly affected. As far as chemical composition is concerned, chickens receiving the lupin-containing feed showed a significant (P ⪬ 0.01 increase in the ash content in breast muscles. On the contrary, in thigh muscles in group E2, the ash content decreased significantly (P ⪬ 0.01. The content of calcium showed an increasing trend in both breast and thigh muscles in both experimental groups. In contrast, the content of magnesium in chicken muscles in both experimental groups decreased. These differences were significant (P ⪬ 0.01 only in thigh muscles. Our results show that lupin seed is a suitable substitute for NSs contained in soybean extracted meal. It is considered optimal to replace up to one third of NSs contained in

    Some components of plant-based meals, such as saponins and vegetal proteins, have been proposed as inducers of intestinal inflammation in some fish. However, the molecular and cellular bases for this phenomenon have not been reported. In this work, zebrafish were used as a model to evaluate the effects of individual soybean meal components, such as saponins and soy proteins. Zebrafish larvae fed a fish meal feed containing soy components were assessed according to low and high inclusion levels. The granulocytes associated with the digestive tract and the induction of genes related to the immune system were quantitated as markers of the effects of the dietary components. A significant increase in the number of granulocytes was observed after feeding fish diets containing high saponin or soy protein contents. These dietary components also induced the expression of genes related to the innate immune system, including myeloid-specific peroxidase, as well as the complement protein and cytokines. These results reveal the influence of dietary components on the stimulation of the immune system. These observations could be significant to understanding the contributions of saponin and soy protein to the onset of enteritis in aqua-cultured fish, and this knowledge may aid in defining the role of the innate immune system in other inflammatory diseases involving dietary components in mammals.

    We formulated experimental diets for hybrid tilapia to investigate the effects of replacing dietary soybean meal (SBM) or cottonseed meal (CSM) by completely hydrolyzed feather meal (defatted rice bran as the carrier; abbreviated as CHFM), with emphasis on fish growth, the composition of adhesive gut bacteria, intestinal and hepatic immune responses, and disease resistance. A series of four isonitrogenous (33% crude protein) and isolipidic (6% crude lipid) diets were formulated to replace the isonitrogenous percentages of CSM or SBM by 6% or 12% CHFM. Quadruplicate groups of healthy and uniformly sized hybrid tilapia were assigned to each experimental diet. Fish were hand fed three times a day for 8 weeks at a rearing temperature of 25-28 °C. The growth performance of hybrid tilapia fed diets with partial replacement of dietary SBM or CSM with CHFM was comparable to the group of fish fed the control diet. The CHFM-containing diets affected the intestinal autochthonous bacterial community in similar ways. All CHFM-containing diets stimulated the expression of heat shock protein 70 in the intestine but suppressed its expression in the liver. Only the CHFM6/SBM diet stimulated the expression of interleukin-1β in intestine, and no effects were observed in all diets to the expression of interleukin-1β in liver. Thus, regarding the immune response in the intestine and liver, CHFM is a good alternative protein source that induces less stress in the host. CHFM did not affect disease resistance to Aeromonas hydrophila infection in hybrid tilapia. These data suggest that CHFM is a good alternative to partially replace SBM and CSM in tilapia feed.

    The aim of the research was to study the effects of an insect meal from Hermetia illucens larvae (HILM) as complete replacement of soybean meal (SBM) on productive performance and blood profiles of laying hens, from 24 to 45 wk of age. A total of 108 24-week-old Lohmann Brown Classic laying hens was equally divided into 2 groups (54 hens/group, 9 replicates of 6 hens/group). From 24 to 45 wk of age, the groups were fed 2 different isoproteic and isoenergetic diets: the control group (SBM) was fed a corn-soybean meal based diet, while in the HILM group the soybean meal was completely replaced by Hermetia illucens larvae meal. Feed intake, number of eggs produced, and egg weight were recorded weekly along the trial. At 45 wk of age, blood samples were collected from 2 hens per replicate. The use of HIML led to a more favorable (P meal produced a higher percentage of eggs from small (S), medium (M), and extra-large (XL) classes (P meal, while creatinine was higher (P meal can be a suitable alternative protein source for laying hens even if the complete replacement of soybean meal needs further investigation to avoid the negative effects on feed intake. © 2017 Poultry Science Association Inc.

    Two studies were conducted using adult dogs to evaluate the effect of increasing the inclusion of soybean meal (SBM) in an adult dog food on body composition, hematological and biochemical blood analyses, and total tract nutrient digestibility. Nutritionally complete and balanced diets were formulated with commercial-grade SBM (48% CP) to replace 0, 10, 20, or 30% of the protein provided by dried chicken protein resulting in final SBM inclusion of 0, 6.0, 11.5, and 17.0% (as-fed basis), respectively. In study 1, diets were fed during a 24-wk feeding trial using 36 female (spayed), adult hounds to evaluate food intake, BW, body composition, and blood measurements. There were no diet-related differences in food intake or BW. Body composition responded in a quadratic manner to increased dietary SBM inclusion with the percentage (%) of lean mass responding positively (P dogs. Serum concentrations of C-reactive protein and IGF-1 were similar among diets. In study 2, diets were evaluated in a digestibility study using 12 adult dogs in a 4 × 4 Latin square design. Increased SBM inclusion was associated with linear increases in the digestibility of CP (P dogs.

    This study was conducted to determine the comparative efficacy of partial fish meal (FM) replacement (up to 50%) with fermented soybean meal (FSBM; SoELAB, PepSoyGen and Soytide) or enzymatically prepared SBM (HP 300) on growth performance, nutrient digestibility and fecal microflora in weaned pigs. A total of 100 weaned pigs (body weight 6.59 ± 0.29 kg) were used in experimental feeding trials, lasting for up to 6 weeks, and were randomly allotted to five groups with four block replicates of five pigs per pen serving as one block. Dietary treatments were as follows: (i) 100% FM, (ii) 50% FM + 50% SoELAB-54, (iii) 50% FM + 50% PepSoyGen, (iv) 50% FM + 50% Soytide and (v) 50% FM + 50% HP 300. Concerning growth performance, none of the treated SBM preparations demonstrated any significantly different effect compared with FM treatment. With respect to nutrient digestibility, SoELAB and HP 300 treatments demonstrated no significant difference compared with FM treatment. Lastly, none of the SBM preparations demonstrated any significant differences in animal fecal score and all of the differentially treated SBM increased fecal Lactobacillus counts, while maintaining similar Escherichia coli counts compared with FM treatment. © 2014 Japanese Society of Animal Science.

    The aim of this study was to evaluate the effect of zinc supplementation on productive performance and antioxidant status in laying ducks. Five-hundred-four laying ducks were divided into 7 treatments, each containing 6 replicates of 12 ducks. The ducks were caged individually and fed a corn-soybean meal and wheat bran basal diet (37 mg Zn/kg) or the basal diet supplemented with 15, 30, 45, 60, 75, or 90 mg Zn/kg (as zinc sulfate). During the early laying period of 10 d (daily egg production 80%). Average egg weight and feed intake did not differ among the groups of graded Zn supplementation.The egg quality was not affected by dietary Zn, including the egg shape index, Haugh unit, yolk color score, egg composition, and shell thickness. The activities of plasma activities of total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-PX) increased in a quadratic manner (P < 0.001) with increasing supplemental Zn. Plasma concentration of Zn increased quadratically (P < 0.05) as dietary Zn increased. The hepatic activity of Cu/Zn-SOD and GSH-PX increased quadratically (P < 0.05) with increasing dietary Zn. Plasma Zn concentrations were positively correlated with activities of T-SOD (P < 0.05), and positively with plasma Cu. Plasma concentration of reduced glutathione was correlated with plasma Cu. In conclusion, supplementation of Zn at 30 or 45 mg/kg to a corn-wheat bran and soybean basal diet may improve the productive performance and enhance the antioxidant capacity. © 2017 Poultry Science Association Inc.

    This study aimed to determine the impact of replacing soybean meal with peanut cake in the diets of crossbred Boer goats as determined by carcass characteristics and quality and by the fatty acid profile of meat. Forty vaccinated and dewormed crossbred Boer goats were used. Goats had an average age of 5 mo and an average BW of 15.6 ± 2.7 kg. Goats were fed Tifton-85 hay and a concentrate consisting of corn bran, soybean meal, and mineral premix. Peanut cake was substituted for soybean meal at levels of 0.0, 33.33, 66.67, and 100%. Biometric and carcass morphometric measurements of crossbred Boer goats were not affected by replacing soybean meal with peanut cake in the diet. There was no influence of the replacement of soybean meal with peanut cake on weight at slaughter ( = 0.28), HCW ( = 0.26), cold carcass weight ( = 0.23), noncarcass components of weight ( = 0.71), or muscularity index values ( = 0.11). However, regression equations indicated that there would be a reduction of 18 and 11% for loin eye area and muscle:bone ratio, respectively, between the treatment without peanut cake and the treatment with total soybean meal replacement. The weights and yields of the commercial cuts were not affected ( > 0.05) by replacing soybean meal with peanut cake in the diet. Replacing soybean meal with peanut cake did not affect the pH ( = 0.79), color index ( > 0.05), and chemical composition ( > 0.05) of the meat (). However, a quadratic trend for the ash content was observed with peanut cake inclusion in the diet ( = 0.09). Peanut cake inclusion in the diet did not affect the concentrations of the sum of SFA ( = 0.29), the sum of unsaturated fatty acids (UFA; = 0.29), or the sum of PUFA ( = 0.97) or the SFA:UFA ratio ( = 0.23) in goat meat. However, there was a linear decrease ( = 0.01) in the sum of odd-chain fatty acids in the meat with increasing peanut cake in the diet. Soybean meal replacement with peanut cake did not affect the n-6:n-3 ratio ( = 0.13) or the

    Full Text Available This trial was performed to study the effects of replacing soybean meal (SBM with fermented rapeseed meal (RSM on growth performance, serum biochemistry variable and intestinal morphology of broilers. A total of 640 d-old Arbor Acres broiler chicks were randomly allocated to 4 dietary treatments, 4 pens per treatment and 40 birds per pen for a 6-wk feeding trial. In the four treatment groups, fermented RSM replaced soybean meal at 0, 5, 10, and 15%, respectively. On 21 d and 42 d, two birds from each pen were randomly selected and slaughtered. Blood samples and sections of duodenum, jejunum, and ileum were collected for measurement of serum biochemical variables and intestinal morphology, respectively. Results showed that body weight gain (BWG and feed conversion (FC were significantly (p<0.01 poorer for birds fed the 15% fermented RSM diet than those fed with 0, 5 and 10% fermented RSM diets during all periods. Compared with 0 and 5% fermented RSM groups, IgG content in the serum of birds in 10 and 15% fermented RSM groups was improved (p<0.01 urea nitrogen content of serum was reduced (p<0.01 during both growing and finishing periods. However, IgM, phosphorus and calcium levels increased (p<0.05 only during the growing period. Increased (p<0.05 villus height was observed in the duodenum and jejunum of broilers fed the diet with 10% fermented RSM. In addition, villus height to crypt depth ratio in the jejunum was significantly higher (p<0.01 for birds fed the diet with 10% fermented RSM than for those fed diets with 0, 5 and 15% fermented RSM. The present results suggest that RSM fermented with Lactobacillus fermentum and Bacillus subtilis is a promising alternative protein source and that it could be safely used replace up to 10% SBM in broiler diets.

    Full Text Available Aflatoxins, fumonisins and zearalenone take part of the most studied mycotoxin groups due to their toxic effects on animal and human health. This research evaluated samples of soybeans meal used in animal food industry. A hundred and twenty one soybean meal samples were analyzed, so that 66 were analyzed before the industrial processing of micronization and 55 after it. The bromatological average of samples before micronization showed the following answers: 12.4% moisture; 46.4% protein; 79.5% protein solubility; 5.9% ash content; 2.2% fat; 4.3% fiber and 0.02 (ΔpH of urease activity. The samples of micronization soybean meal showed 7.0% average values for moisture and 48.6% for crude protein. The mycotoxin levels were low in natura soybean meal; therefore, average values were 0.5μg kg-1, 29.6μg kg-1 and 56.8μg kg-1 for aflatoxin, zearelenone and fumonisin, respectively. After micronization, the average values for the studied samples were 1.3μg kg-1, 67.5μg kg-1 and 89.1μg kg-1, respectively for the same mycotoxins. The results for bromatological and mycotoxin analyses indicate similarity with the established patterns according to the Brazilian Compendium for Animal feed and reference literature. However, at least one of the three studied mycotoxin was detected in all of the analyzed samples and there was greater contamination of soybeans meal after the micronization process.

    Full Text Available This study aimed to evaluate the effect of replacing soybean meal with soybean in multiple supplements on nutritional parameters, microbial efficiency and productive and reproductive performance of heifers grazing in Urochloa decumbens during the drought period. Were used 39 crossbred heifers of initial age and initial weight of 21 months and 309.5±7 kg, respectively. The experimental design was completely randomized with four treatments with eight replicates, and a control treatment with seven replications. Two treatments had soybean meal as the protein source and two treatments had soybean as the protein source, containing 25% and 40% crude protein. The amount of supplement offered was 1.0 kg/animal/day. The animals of the control group received only mineral salt ad libitum. The supplemented animals had higher average daily gain (ADG than control animals (P<0.10, and there was no difference in ADG among the supplements (P>0.10. There was an effect of supplementation (P <0.10 on intake of dry matter (DM, organic matter (OM, crude protein (CP, ether extract (EE, non-fiber carbohydrates (NFC, total digestible nutrients (TDN and neutral detergent fiber corrected for ash and protein (NDF. There were no differences (P>0.10 on intake of OM and DM grazing between the supplemented and non-supplemented. Supplementation improved DM digestibility and all constituents of the diet (P<0.10. It was found that the provision of multiple supplements optimizes the performance of heifers grazing during the dry season, and that the substitution of soybean meal by soybean did not improve productive performance of animals.

    Extruded soybean meal (ESBM) was evaluated as a protein source for partial replacement of fish meal (FM) in diets of juvenile Litopenaeus vannamei. In the control diet (Diet 1), FM protein was replaced with increasing dietary levels of ESBM (4.28%, 8.40%, 12.62%, 16.82%, and 25.26%) at 10%, 20%, 30%, 40%, and 60% levels (Diets 2 to 6, respectively). An eight-week feeding trial was conducted on 720 juvenile shrimp (0.67 g ± 0.01 g mean initial weight), and nutrient digestibility of the six diets was determined. ESBM could replace 20% of FM without causing a significant reduction in growth of shrimp, but other dietary treatments strongly affected whole body composition. Crude protein content of the whole body fed Diet 6 was significantly lower than that fed Diet 2 ( P digestibilities of Diets 5 and 6 were significantly lower than that of Diet 1 ( P Digestibility of lipids ranged from 96.97% in Diet 6 to 98.34% in Diet 3, whereas dry matter digestibility decreased with increasing replacement level. This study indicates that 20% FM replacement with ESBM in the basic diet containing 40% protein and 30% FM is optimal for juvenile L. vannamei.

    Full Text Available The study evaluated the effects of replacing soybean meal and soybean oil respectively with extruded linseed and linseed oil on the productive performances and meat quality traits in lambs slaughtered at 90 days. Lambs weaned at 40 days were divided into 3 groups (N.=10 fed ad libitum for 6 weeks as follows: C (control, commercial feed containing soybean meal and soybean oil; LO (feed containing linseed oil instead of soybean oil; EL (feed containing extruded linseed. Meat quality traits were evaluated on the Longissimus lumborum (Ll and Semimembranosus (Sm muscles. The lambs’ growth performances and the slaughtering and sectioning data did not differ between groups. The redness of meat was significantly higher (P<0.05 for the LO and EL groups compared to the control for both the muscles tested. Ll meat samples of the EL group showed a greater cooking loss compared to LO (P<0.01 and to the control (P<0.05. The amount of linoleic acid in raw Ll meat samples was significantly (P<0.01 lower in both LO and EL groups with respect to control. The concentration of α-linolenic acid was significantly (P<0.01 higher in the EL group and this positively affected the total content of ω3 as well as the ω6/ω3 ratio.

    1. Herein, it was investigated whether different particle size distributions of feed ingredients achieved by grinding through a 2- or 3-mm grid would have an effect on precaecal (pc) amino acid (AA) digestibility. Maize and soybean meal were used as the test ingredients. 2. Maize and soybean meal was ground with grid sizes of 2 or 3 mm. Nine diets were prepared. The basal diet contained 500 g/kg of maize starch. The other experimental diets contained maize or soybean meal samples at concentrations of 250 and 500, and 150 and 300 g/kg, respectively, instead of maize starch. Each diet was tested using 6 replicate groups of 10 birds each. The regression approach was applied to calculate the pc AA digestibility of the test ingredients. 3. The reduction of the grid size from 3 to 2 mm reduced the average particle size of both maize and soybean meal, mainly by reducing the proportion of coarse particles. Reducing the grid size significantly (P digestibility of all AA in the soybean meal. In maize, reducing the grid size decreased the pc digestibility of all AA numerically, but not significantly (P > 0.050). The mean numerical differences in pc AA digestibility between the grid sizes were 0.045 and 0.055 in maize and soybean meal, respectively. 4. Future studies investigating the pc AA digestibility should specify the particle size distribution and should investigate the test ingredients ground similarly for practical applications.

    The present research carried out to measure digestible (DE) and Metabolizable Energy (ME) for fishmeal and soybean meal in rainbow trout with two different sizes (120 and 220 g mean body weights). DE and ME are evaluation systems for feedstuffs and also, necessary for diet formulation. The fishes were maintained in metabolic chamber with single ingredient assay of feeding and chromic oxide (Cr2O3) was used as an external marker using total fecal collection method. Gross energy and chromic oxide values measured in feces, fishmeal and soybean meal. The results indicated that DE offishmeal was 3700 and 3591 kcal kg(-1) in 120 and 220 g body weight rainbow trout, respectively. Soybean meal had 3004 and 2889 kcal kg(-1) respectively. Calculated ME from DE were 3204 and 3110 kcal kg(-1) for fishmeal and 2601 and 2502 kcal kg(-1) for soybean meal in 120 and 220 g rainbow trout, respectively. The results showed that rainbow trout can utilize fishmeal more efficiently than soybean meal.

In the first trial, 35 cockerels per studied feedstuff (corn and soybean meal were distributed in a completely randomized experimental design with four treatments of seven replicates of one bird each. The evaluated treatments were: ingredient (corn and soybean meal with no enzyme addition, with the addition of an enzyme complex (xylanase, amylase, protease - XAP, xylanase, or phytase. Precise feeding method was used to determine true metabolizable energy corrected for nitrogen balance (TMEn. The use of enzymes did not result in any differences (p>0.05 in soybean meal TMEn, but phytase improved corn TMEn in 2.3% (p=0.004. In the second trial, 280 seven-day-old broiler chicks were distributed in a completely randomized experimental design with seven treatments of five replicates of eight birds each. Treatments consisted of corn with no enzyme addition or with the addition of amylase, xylanase, phytase, XAP complex, XAP+phytase combination, or xylanase/ pectinase/β-glucanase complex (XPBG. Corn was supplemented with macro and trace minerals. Total excreta collection was used to determine apparent metabolizable energy corrected for nitrogen balance (AMEn. Differences were observed (p=0.08 in AMEn and dry matter metabolizability coefficient (p=0.03. The combination of the XAP complex with phytase promoted a 2.11% increase in corn AMEn values, and the remaining enzymes allowed increased between 0.86% and 1.66%.

    Salmonella colonization in poultry may be influenced by grain type and particle size. Broilers reared either in nonlitter cage-based housing or in a conventionally floored litter house from 0 to 42 d were assigned to 1 of 4 dietary treatments: 1) ground corn-soybean meal (C, 560 microm), 2) coarsely ground corn-soybean meal (CC, >1,700 microm), 3) ground triticale-soybean meal (T, 560 microm), or 4) whole triticale-soybean meal (WT). A 4-strain cocktail of Salmonella enterica was orally gavaged into each chick at placement. Growth performance, cecal and fecal Salmonella populations, gizzard and proventriculus pH, intestinal size, jejunum histomorphometry, and carcass yields were measured. Broilers responded differently to the dietary treatments according to the housing system used. At 42 d, birds reared on litter and fed ground grain had greater BW than those fed coarse grain (2.87 vs. 2.71 kg), whereas cage-reared broilers fed ground triticale were heavier than those fed corn (2.75 vs. 2.64 kg). Broilers raised on litter had a better feed conversion ratio than those raised in cages (1.71 vs. 1.81 g/g). Independent of the housing system, relative eviscerated carcass weights of birds fed T and C were heavier than those of CC- and WT-fed broilers (762 vs. 752 g/kg). Generally, the jejunum villus area and mucosal depth were larger, whereas the small intestine was lighter and shorter in broilers raised on litter. Relative gizzard weights of broilers raised on litter and fed the coarser diets were heavier than those of broilers reared in cages and fed finely ground diets. Feeding whole or coarsely ground grains decreased cecal Salmonella populations in 42-d-old broilers (3.8, 3.9, 4.4, and 4.4 log most probable number/g for CC, WT, C, and T, respectively). Additionally, 42-d-old broilers reared on litter had lower cecal Salmonella populations than those in cages (3.8 vs. 4.4 log most probable number/g). In conclusion, as a feed ingredient, triticale is a good

    Two trials were conducted to study the effects of alfalfa leaf meal (ALM) in receiving diets of steers. In trial one, ninety-six medium frame, Angus and Angus cross steer calves (average initial weight 500 lb) were allotted to a heavy or light weight block and then randomly assigned to one of four dietary treatments for a 29-day receiving trial. In trial two, sixty medium frame, Angus and Angus cross steer calves (average initial weight 518 lb) were allotted to one of ten dietary treatments. Trial two was divided into two periods, defined as a receiving period, 29 days, and a step-up period, 33 days. In trial one, treatments were control (supplemental soybean meal), alfalfa leaf meal (ALM) providing 33%, 66%, or 100% of supplemental protein; the balance was soybean meal. Receiving diets were formulated to contain .54 Mcal NE{sub g} /lb dry matter, 14% crude protein, .6 % Ca and .3 % P. In study two, treatments were control (supplemental soybean meal), ALM providing 33%, 66%7 100% of supplemental protein, the balance was soybean meal and urea or a blend of ALM and blood meal (93 % ALM and 7 % blood meal) to provide supplemental protein. Each protein treatment was fed in diets consisting of cracked or whole corn. Trial two receiving diets were formulated to contain .54 Mcal NE{sub g} /lb dry matter, 14% crude protein, .6 % Ca and .3 % P, step-up diets were formulated to contain .58 Mcal NE9 /lb dry matter, 11.3% crude protein, .6 % Ca and .3 % P.

    The experiment investigated the effects of increasing dietary levels of bacterial protein meal (BPM) on various blood parameters reflecting protein and fat metabolism, liver function, and purine base metabolism in growing pigs. Sixteen barrows were allocated to four different experimental diets....... The control diet was based on soybean meal. In the other three diets soybean meal was replaced with increasing levels of BPM, approximately 17%, 35%, and 50% of the nitrogen being derived from BPM. Blood samples from the jugular vein were taken when the body weights of the pigs were approximately 10 kg, 21 kg......, 45 kg, and 77 kg. The blood parameters reflecting fat metabolism and liver funtion were not affected by diet.

    The complex, interacting influences on eating behavior and energy expenditure prevent elucidation of the causal role of any single factor in the current obesity epidemic. However, greater variety in the food supply, particularly in the form of highly palatable, energy-dense foods, has likely made a contribution. This study was undertaken to test the hypothesis that greater dietary variety is associated with greater caloric intake within individual meals consumed by free-feeding, socially-housed female rhesus monkeys. Meal patterns were assessed during two, two-week dietary phases. One phase consisted of a choice between a standard chow diet and a highly palatable diet (HPD). The other phase consisted of access to the chow only. Food intake for each subject was recorded continuously using previously validated, automated feeders, and a meal was defined based on a minimum kilocalorie requirement and a minimum inter-meal interval. During the choice condition, animals electively consumed mixed meals that incorporated both diets as well as other meals that consisted exclusively of a single diet - chow-only or HPD-only. Animals consumed the most calories per meal when the meal was comprised of both the chow and HPD, which differed in caloric density, flavor, and texture. Interestingly, however, there was no significant difference in the amount of calories consumed as HPD-only meals in the choice condition compared to meals in the chow-only, no choice condition, suggesting consumption of a single food during a meal, regardless of palatability, provides a constant sensory experience that may lead to more rapid habituation and subsequent meal cessation. Additionally, during the dietary choice condition, animals consumed fewer calories in the form of chow-only meals. Thus, the present results suggest that limiting dietary variety, regardless of palatability, may be a useful strategy for weight loss in overweight and obese individuals by reducing caloric intake within

    An experimental study was conducted to examine the combined effects of adding a dietary protease, reducing the levels of soybean meal (SBM) and introducing corn gluten meal (CGM) in the ration of a group of broilers reared on a commercial Greek farm. Five hundred forty chicks were divided into three dietary treatments with six replicates of thirty birds each. The first group (Control) was fed a conventional diet based on corn and soybean meal, containing 21% w/w crude protein (CP). The second group (Soy-Prot) was supplied a corn and SBM-based diet containing a lower level of CP (20% w/w) and 200 mg of the protease RONOZYME® Proact per kg of feed. The third group (Gluten-Prot) was fed a diet without soybean-related constituents which was based on corn and CGM and with CP and protease contents identical to those of the diet of the Soy-Prot group. Body weight, feed intake, feed conversion ratio (FCR), intestinal microbiota populations and morphology, meat quality and cost were evaluated. Furthermore, a partial life cycle assessment (LCA) was performed in order to assess the potential environmental performance of the systems defined by these three dietary treatments and identify their environmental hot-spots. The growth performance of the broilers supplied the Soy-Prot diet was similar to the broilers supplied the Control diet. However, the broilers which were fed the Gluten-Prot diet at the end of the trial showed a tendency (P≤0.010) for lower weight gain and feed intake compared to those of the Control diet. When compared to the Control group, lower counts of C. perfringens (P≤0.05) were detected in the ileum and cecum parts, and lower counts of F. necrophorum (P≤0.001) were detected in the cecum part of the birds from the Gluten-Prot group. The evaluation of intestinal morphometry showed that the villus height and crypt depth values were not significantly different (P>0.05) among the experimental groups for the duodenum, jejunum and ileum parts.

    Ninety-six medium frame, Angus and Angus cross steer calves (average initial weight 540 lb.) were allotted to a heavy or light weight block and then randomly assigned to one of four dietary treatments for a 167 or 189-day finishing phase, respectively. Treatments were control (supplemental soybean meal), alfalfa leaf meal (ALM) providing 33%, 66%, 100% of supplemental protein. Finishing diets were formulated to contain .61 Mcal NE{sub g}/lb dry matter, 12.5% crude protein, .6 % Ca and .3 % P. There were no significant (P >.05) effects of dietary treatments on daily gain or dry matter required /lb of gain. Steers fed 100 % ALM consumed more (P <.05) dry matter than steers fed either of the other three treatments. Dry matter consumption increased linearly (P >.05) with increasing ALM. There was no significant (P >.05) dietary treatment effect on marbling, KPH %, yield grade, quality grade, or liver abscesses. There was an apparent trend in reduced liver abscess incidence in steers fed 100 % ALM. Steers fed 66 % ALM had significantly (P <.05) greater backfat measurements, backfat also had a cubic effect (P <.05). Hot carcass weight had a quadratic relation (P <.05) with level of ALM. Substituting alfalfa leaf meal for soybean meal in diets of finishing steers increased DM intake, but this increase was accompanied by an increase in gain which resulted in similar feed efficiency. There may be an advantage in blending ALM and soybean meal as feed efficiency was improved when cattle were fed the blend. Also, feeding ALM may result in lower incidence of liver abscess.

    The influence of tannin from tea waste and gambier as natural tannin sources on ruminal protein degradability was studied in this investigation. The soybean meal was used as protein source in this investigation. There were three treatments in this investigation mainly without protection (NT); protection with tea waste (Tt); and protection with gambier (Tg). The measured parameters consisted of in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), and the ruminal fermentation characteristics. Results of this experiment showed that protection with tannin from tea waste as well as gambier increased (pRUP) in Tt and Tg group was higher than that in NT group (66.29 and 69.20 vs 51.10%). The ruminal protozoa population decreased (pRUP. The ruminal protozoa population and ammonia concentration, on the other hand, were decreased by tannin protection from those tannin natural sources. The natural tannin from gambier was the most effective protection agent for soybean meal protein.

    A total of 15 primiparous sows (Landrace × Yorkshire) and their litters were used in the current study to evaluate the efficacy of cellulase supplementation on the production performance of sows and piglets. Pigs were randomly allocated into one of three treatments with five replicates per treatment. The dietary treatments were as follows: (i) CON (corn-soybean meal-based control); (ii) EZ1 (CON + 0.05% cellulase); and (iii) EZ2 (CON + 0.10% cellulase). The supplementation of cellulase had no effect (P > 0.05) on body weight and feed intake of lactating sows. At weaning, back fat thickness loss decreased (P = 0.04) linearly in EZ1 and EZ2 treatments. The average daily gain (ADG) of piglets increased (linear P = 0.06, quadratic P = 0.04)) during days 14 to 21 as well as at days 21 to 25 (linear P = 0.03 and quadratic P = 0.01) with the increase in the level of supplemented enzyme. Dry matter and nitrogen digestibility increased (linear P = 0.01) in lactating sows fed EZ1 and EZ2 diet compared with CON. In conclusion, it is suggested that cellulase supplementation to corn-soybean meal based diet exerts beneficial effects to sows in reducing their back fat thickness loss at weaning and also helps to improve nutrient digestibility. It also helped to improve the ADG of piglets. © 2015 Japanese Society of Animal Science.

    To assess the impact on food-related cost of meals to fulfill the new compulsory dietary standards for primary schools in France. A descriptive study assessed the relationship between the level of compliance with the standards of observed school meals and their food-related cost. An analytical study assessed the cost of series of meals published in professional journals, and complying or not with new dietary standards. The costs were based on prices actually paid for food used to prepare school meals. Food-related cost of meals. Parametric and nonparametric tests from a total of 42 and 120 series of 20 meals in the analytical and descriptive studies, respectively. The descriptive study indicated that meeting the standards was not related to cost. The analytical study showed that fulfilling the frequency guidelines increased the cost, whereas fulfilling the portion sizes criteria decreased it. Series of meals fully respecting the standards (ie, frequency and portion sizes) cost significantly less (-0.10 €/meal) than series not fulfilling them, because the standards recommend smaller portion sizes. Introducing portion sizes rules in dietary standards for school catering may help increase dietary quality without increasing the food cost of meals.

    Ramoplanin A2 is the last resort antibiotic for treatment of many high morbidity- and mortality-rated hospital infections, and it is expected to be marketed in the forthcoming years. Therefore, high-yield production of ramoplanin A2 gains importance. In this study, meat-bone meal, poultry meal, and fish meal were used instead of soybean meal for ramoplanin A2 production by Actinoplanes sp. ATCC 33076. All animal origin nitrogen sources stimulated specific productivity. Ramoplanin A2 levels were determined as 406.805 mg L(-1) in fish meal medium and 374.218 mg L(-1) in poultry meal medium. These levels were 4.25- and 4.09-fold of basal medium, respectively. However, the total yield of poultry meal was higher than that of fish meal, which is also low-priced. In addition, the variations in pH levels, protein levels, reducing sugar levels, extracellular protease, amylase and lipase activities, and intracellular free amino acid levels were monitored during the incubation period. The correlations between ramoplanin production and these variables with respect to the incubation period were determined. The intracellular levels of L-Phe, D-Orn, and L-Leu were found critical for ramoplanin A2 production. The strategy of using animal origin nitrogen sources can be applied for large-scale ramoplanin A2 production.

    The effect of soybean meal fermented by Aspergillus awamori on the acute lethality of acetaldehyde, pentobarbital sleeping time, and cytochrome P-450 content of the hepatic microsomes was studied in mice. Most of the daidzin and genistin in soybean meal (SBM) were converted into the respective aglycones, daidzein and genistein, by fermentation. In experiment 1, mice were fed isonitrogenic test diets with one of the following five protein sources for 28 d: casein, SBM, fermented and hot-air-dried SBM (FSBM-HD), fermented and freeze-dried SBM (FSBM-FD), or methanol-extracted FSBM-FD (FSMB-FD-R). The acute lethality of acetaldehyde in mice fed the FSBM-FD diet was significantly lower than that in mice fed the SBM, FSBM-HD, or FSBM-FD-R diet. In experiments 2 and 3, mice were fed isonitrogenic test diets with one of the following four protein sources for 28 d: casein, SBM, FSBM-FD, and FSBM-FD-R. The pentobarbital sleeping time was significantly shorter and the cytochrome P-450 content was significantly higher in the mice fed the FSBM-FD diet than the respective value in mice fed the other test diets. In experiment 4, mice were fed one of eight diets which contained different levels of aglycone obtained by varying the proportion of FSBM-FD and FSBM-FD-R, for 28 d. The cytochrome P-450 content in hepatic microsomes increased as the dietary level of isoflavonoid aglycones increased, but there was a saturation phenomenon. These results suggest that soy isoflavonoid aglycones are more potent inducers of cytochrome P-450 than isoflavonoid glycosides.

Fifty-six (Landrace x Large White castrated males with an initial average body weight of 50 kg were allocated to two experimental groups: a control group in which pigs received a traditional soybean meal-based diet, and a treatment group in which soybean meal was replaced by vegetable protein sources (i.e. sunflower meal, potato protein, corn gluten feed, faba beans and dehydrated alfalfa meal, mainly locally grown and not genetically modified. Pigs were slaughtered at approximately 160 kg body weight. Dietary treatment had no significant effect on fattening performance, or meat, fat or dry-cured ham properties. Results suggest that it is possible to feed heavy pigs a soybean-free diet without impairing fattening performance or the quality of meat and Italian PDO (Protected Designation of Origin hams.

    Full Text Available An experiment was conducted to examine the effects of different dietary protein sources (soybean meal vs whey protein on piglet meat quality characteristics. Eighteen castrated male Large White × Duroc × Landrace piglets were randomly assigned to 2 groups. Piglets were kept in individual metabolic cages and fed ad libitum over a period of 38 days the following 2 diets: diet SB, which was formulated to meet the nutrient requirements of piglets using soybean meal as the main crude protein source and diet WP, where SB was totally replaced by a mixture of whey proteins on equal digestible energy and crude protein basis. At the end of the experiment, piglets were weighed and slaughtered. After overnight chilling, samples of Longissimus dorsi muscle were taken and were used for meat quality measurements.          No significant differences were observed in the values of pH, colour, water holding capacity, shear force and intramuscular fat content of L. dorsi muscle between the dietary treatments. Measurement of lipid oxidation values showed that dietary supplementation with different protein sources did not influence meat antioxidant properties during refrigerated storage. The SB piglets had lower 14:0 (P<0.01 and higher 18:3n-3 (P<0.001 levels in intramuscular fat in comparison with WP piglets. However, these changes were attributed to background differences in the dietary FA profile and not to a direct protein source effect. The results of this preliminary study indicate that the examined dietary protein sources (soybean meal or whey protein do not have a significant effect on meat quality characteristics of piglets.

    The aim of this experiment was to investigate the physiological and growth response of young turkeys (up to 8 weeks of age) to dietary replacement of soybean meal (SBM) by soy protein concentrate (PC) or protein isolate (PI). This replacement resulted in a differentiated dietary concentration of α-galactosides of over 2.5% in the SBM diet, approximately 2% with a mixture SBM and PC, 1% with a PC diet and 0.1% with a PI diet. Each treatment was applied in two ways: with lower (3.5%) or higher (5.3%) dietary crude fibre content, made by supplementation with soybean hulls. The highest and lowest body weight of turkeys was recorded both after the first and second 4-week half of the study in the PC and PI-type diets respectively. A gradual withdrawal of α-galactosides from a diet was accompanied by a decline in ileal tissue mass, ileal viscosity and activity of endogenous maltase (the latter was found to be significant at 4 weeks of age). At the same time, two-way anova revealed that an elevated level of crude fibre (HF treatment) caused an increase in ileal tissue mass (p diet, in contrast to dietary crude fibre level, significantly affected the caecal metabolism. The rate of bacterial production of short-chain fatty acids in the caeca was distinctly diminished by dietary withdrawal of α-galactosides. In conclusion, the soy protein concentrate, in contrast to the protein isolate preparation, exerted positive effects on the turkeys' growth and gastrointestinal tract physiology and should be considered as an effective SBM substitute. © 2009 The Authors.

The study was conducted in clear water in fifteen 800 L tanks equipped with aeration systems, constant heating (29 ºC, and daily water exchange (30%. Each tank was stocked with 37.5 shrimp/m3 (3.03±0.14 g. Feed was supplied four times a day, at 6% of the initial biomass, adjusted daily. After 42 days, the weight gain of shrimp fed diets with 0 and 25% protein replacement was higher than that observed in shrimp fed 100% replacement, and there were no differences among those fed the other diets. Feed efficiency and survival did not differ among shrimp fed different protein replacements. There was a negative linear trend for growth parameters and feed intake as protein replacement with soybean protein concentrate increased. Fish meal by-product can be replaced by up to 75% of soybean protein concentrate, with no harm to the growth of Pacific white shrimp.

    Cottonseed meal (CSM) is an alternative source of protein, and previous studies have been shown that it can replace soybean meal (SBM) without decrease animal performance. However, Brazilian CSM has a different chemical composition compared with the usual CSM reported in the literature. The objective of this experiment was to evaluate the effects of replacing SBM for Brazilian CSM on performance and energy balance of mid-lactating dairy cows. Forty-two Holstein cows were used in a replicate 3 × 3 Latin square design. Increasing contents of CSM (0, 15, and 30% of dry matter (DM)) were fed in diets to replace SBM. Milk yield and feed efficiency were linearly reduced with the replacement of CSM for SBM (P = 0.001). Milk fat content tended to increase quadratically (P = 0.07) with CSM addition. Replacing SBM for CSM affected milk protein content quadratically (P = 0.05). Milk urea nitrogen and plasma urea nitrogen (PUN) tended to respond quadratically (P = 0.06 and 0.10) when CSM replaced SBM to the diets. Variation in body weight (BW) also responded quadratically as CSM replaced SBM (P = 0.05). Altogether, the findings suggest better performance when cows receive SBM diet compared with the Brazilian CSM diet.

    The links between dietary patterns, the perception of one’s body weight and diet as well preparing meals are poorly recognised in the literature. In order to develop effective nutritional education and focused interventions, more of such information is thereby required to improve the nation’s health To identify dietary patterns based on declared food consumption rates and subject responses on whether dieting, perception of body weight and diet and preparing meals are linked to such dietary patterns The survey was conducted in 2016 on 344 consumers chosen for age (20-65 years) and their consent for study participation. Rates of eating the foods selected were measured using a 7-point scale. Cluster analysis was used to identify three dietary patterns of behaviour: ‘potentially beneficial to health’, ‘potentially unfavourable for health; deficient’ and ‘potentially unfavourable for health; excessive’. The analysis was performed using IBM SPSS Statistics version 23.0 There were significantly more subjects showing ‘potentially beneficial for health’ behaviour, normal body weight, those dieting (whether now or in the past) and those who evaluated their diet as being very good or good compared to other groups. They were also more involved in preparing their meals at home. Differences were found between the ‘unfavourable for health’ dietary patterns concerning subject’s involvement in meal preparation. The dietary pattern for ‘deficient’ behaviour found lower rates of those preparing their meals at home The pattern of potentially beneficial dietary habits was linked to weight control through a slimming diet and greater involvement in the preparation of food for consumption. The results show the need to develop food choice skills rather than just transferring knowledge in the nutrition education process

    Two experiments were conducted to investigate the effects of replacing soybean meal with gelatin extracted from cow skin and corn protein concentrate as a protein source in broiler diets. Experiments were carried out as a completely randomized design where each experiment involved 4 treatments of 6 replicates and 10 chicks in each pen. Soybean meal proteins in a corn-soy control diet were replaced with 15, 30, and 45% of cow skin gelatin (CSG) or corn protein concentrate (CPC), respectively, in experiments 1 and 2. BW and cumulative feed intake were measured at 7, 21, and 42 d of age. Blood characteristics, relative organs weight and length, ileal digesta viscosity, ileal morphology, and cecal coliform and Salmonella population were measured at 42 d of age. Apparent total tract digestibility of protein was determined during 35 to 42 d of age. Replacement of soybean meal with CSG severely inhibited BW gain, decreased feed intake, and increased FCR in broilers during the experimental period (P ≤ 0.01). The inclusion of CPC reduced BW and increased FCR significantly (P ≤ 0.05) at 21 and 42 d of age without any consequence in feed intake. Protein digestibility was reduced and ileal digesta viscosity was increased linearly by increasing the amount of CSG and CPC in the control diet (P ≤ 0.01). Replacement of soybean meal with CSG and CPC did not significantly alter blood cell profile and plasma phosphorus, creatinine, blood urea nitrogen, Aspartate transaminase, and HDL and LDL cholesterol concentration. The inclusion of CSG linearly (P ≤ 0.05) increased plasma uric acid concentration and alkaline phosphatase activity. Triglyceride and cholesterol levels were decreased significantly (P ≤ 0.05) when the amount of CSG replacement was 15%. The results of this experiment showed that using CSG and CPC negatively affects broiler performance and therefore is not a suitable alternative to soybean meal in commercial diets. © 2015 Poultry Science Association Inc.

    Antioxidative activity of protein hydrolysates was dependent on the raw material, condition of hydrolysis and lipid substrate used in model systems. Soybean meal hydrolysate was more active in lard and in linoleic acid emulsion than caseine hydrolysate, whereas caseine was more active in vegetable oils. Antioxidant activity of evaluated protein hydrolysates in all lipid systems, with or without oxidation catalysts, suggests them as natural food additives for lipid stabilization, thus for improvement of its nutritional value and sensory properties

    Soybean meal is a by-product of soybean oil extraction and contains approximately 44% protein. We performed solid-state fermentation by using Bacillus subtilis strain N-2 to produce a water-soluble fertilizer containing amino acids. Strain N-2 produced a high yield of protease, which transformed the proteins in soybean meal into peptide and free amino acids that were dissolved in the fermentation products. Based on the Plackett-Burman design, the initial pH of the fermentation substrate, number of days of fermentation, and the ratio of liquid to soybean meal exhibited significant effects on the recovery of proteins in the resulting water-soluble solution. According to the predicted results of the central composite design, the highest recovery of soluble proteins (99.072%) was achieved at the optimum conditions. Under these conditions, the resulting solution contained 50.42% small peptides and 7.9% poly-γ-glutamic acid (γ-PGA). The water-soluble fertilizer robustly increased the activity of the rapeseed root system, chlorophyll content, leaf area, shoot dry weight, root length, and root weight at a concentration of 0.25% (w/v). This methodology offers a value-added use of soybean meal. Copyright © 2014 Elsevier B.V. All rights reserved.

The supplements were provided in 6 g/kg of body weight/animal/day, consisting of sunflower crushed, corn, soybean meal and mineral. All the supplements was isonitrogenous and soybean meal was replaced in 0, 20, 40, and 60% for sunflower crushed. The determination of ruminal pH and ammonia was at 0, 2, 4, 6 and 8 h. after feeding and for short-chain fatty acids it was collected at 0 and 6 h. post-feeding. The dry matter intake was not affected (P>0.05 by inclusion of sunflower crushed (mean=6.59 kg/day. There was no significant effect (P>0.05 for pH for the inclusion of sunflower crushed (mean=6.41. For contents of ruminal NH3-N was a significant effect (P <0.05 only for collection time, and ammonia peaks occurred between 2 and 4 h after feeding, with values of 22.56 and 21.40 mg/dL. The total concentration of short chain fatty acids and the C2:C3 ratio was reduced in 9.6 and 15.43%. The ruminal degradability of NDF was not affected by the supplements. The supplementation with sunflower crushed to beef steers grazing, in partial replacement of soybean meal did not alter nutrition parameters.

    The present study aimed to assess the effect of dietary substitution of soybean meal (SBM) with dehulled-micronized faba bean (Vicia faba var. minor) in guinea fowl broilers on their growth traits, carcass quality, and meat fatty acids composition. In this trial, 120 day-old guinea fowl keets were randomly assigned to two treatments which were fed from hatch to 12 weeks of age. Birds were fed two wheat middlings-based diets comprising of a control treatment which contained SBM (78.3 g/kg) and a test diet containing dehulled-micronized faba bean (130 g/kg) as the main protein source. Substituting SBM with faba bean had no adverse effect on growth traits, dressing percentage, or breast and thigh muscles relative weight of the guinea fowls. Conversely, a decrease (pMeat from guinea fowls fed faba bean had less total lipids (pmeat and decreased the saturated fatty acid levels. Moreover, dietary faba bean improved the atherogenic and thrombogenic indexes in guinea fowl breast meat. Results indicated that substitution of SBM with faba bean meal in guinea fowl diet can improve carcass qualitative traits, enhancing also meat lipid profile without negatively affecting growth performance.

    2016-01-01

    Full Text Available Soybean meal was adulterated with melamine with the purpose of boosting the protein content for unlawful interests. In recent years, the near-infrared (NIR spectroscopy technique has been widely used for guaranteeing food and feed security for its fast, nondestructive, and pollution-free characteristics. However, there are problems with using near-infrared (NIR spectroscopy for detecting samples with low contaminant concentration because of instrument noise and sampling issues. In addition, methods based on NIR are indirect and depend on calibration models. NIR microscopy imaging offers the opportunity to investigate the chemical species present in food and feed at the microscale level (the minimum spot size is a few micrometers, thus avoiding the problem of the spectral features of contaminants being diluted by scanning. The aim of this work was to investigate the feasibility of using NIR microscopy imaging to identify melamine particles in soybean meal using only the pure component spectrum. The results presented indicate that using the classical least squares (CLS algorithm with the nonnegative least squares (NNLS algorithm, without needing first to develop a calibration model, could identify soybean meal that is both uncontaminated and contaminated with melamine particles at as low a level as 50 mg kg−1.

    Notoriously, the island of Mauritius has one of the highest prevalence of diabetes in the world. Management of the disease is very important and family meals are undoubtedly beneficial to patients as they promote the development of healthy eating behaviours and food choices. This study has aimed to probe into potential relationship(s) between family meal frequency and individual dietary intake among diabetic patients and to establish whether family cohesion may be a plausible mediator of this relationship. A cross-sectional survey was carried out with a random sample of 384 diabetic patients. The Family Adaptability and Cohesion Evaluation Scale III was used to obtain information on two general aspects of family functioning, that is, cohesiveness and adaptability. Chi-squared (χ (2)) tests, independent sample t-tests and one-way ANOVA were used to determine statistical significance. Pearson correlation was used to examine associations between family meal frequency, individual dietary intake and family cohesion. Hierarchical linear regression models were performed for the mediation analysis. Family meal frequency (breakfast, lunch and dinner) was observed to be positively associated with intake of fish, raw vegetables, dried and fresh fruits, low-fat milk, cheese, yogurt, nuts and light butter and negatively associated with intake of red meat, white rice, white bread, whole egg fried, chocolates, fried cakes, burgers, chips, and fried noodles/rice. Average mediation (52.6 %) was indicated by family cohesion for the association between family meal frequency and individual dietary intake among diabetic patients. Sobel's test further confirmed the trend towards complete mediation (z = 15.4; P relationship between family meal frequency and individual dietary intake among diabetic patients was recorded. The present study is one of the few studies that have examined family cohesion as a mediator of the relationship and to our best knowledge is the first work to

    The school canteen provides a substantial proportion of the daily nutritional intake for many children. There are nutritional standards for school meals, however, it is still difficult to assess the dietary quality. To design a questionnaire for assessing the dietary quality of school meals, quickly and easily. A dietary questionnaire (COMES) was designed on the basis of the current recommendations. COMES consist of 15 items related to the food-frequency and to other characteristics of school meals. Then, a longitudinal prospective study was performed in order to analyze, with COMES, 36 school meals of 4 catering companies from Castilla y León during the academic years 2006-2007 to 2010-2011. Differences in dietary quality menus according to the management system of catering companies (in situ vs. transported) were analyzed by using the Mann-Whitney and the Kruskal-Wallis tests. The significance was reached at p culinary techniques were appropriate. No significant differences were found in the COMES score according to the management system (p=0,87), although catering system provides higher dietary quality. A new tool to assess quickly and easily the nutritional quality of school meals has been proposed. The assessment of the frequency intake of the most problematic foods for schoolchildren with this scale is much more demanding than the current recommendations. Even so, menus analyzed showed an acceptable quality in terms of variety of foods and culinary techniques, although milk frequency in the menus was excessive at the expense of fresh fruit. On the other hand, the transported system (i.e. catering, both hot and cold-holding) provides menus more consistent with the dietary recommendations. Copyright AULA MEDICA EDICIONES 2014.

    Full Text Available Hypoallergenic antibacterial low-molecular-mass peptides were produced from defatted soybean meal in a membrane bioreactor. In the fi rst step, soybean meal proteins were digested with trypsin in the bioreactor, operated in batch mode. For the tryptic digestion of soybean meal protein, optimum initial soybean meal concentration of 75 g/L, temperature of 40 °C and pH=9.0 were determined. Aft er enzymatic digestion, low-molecular-mass peptides were purifi ed with cross-fl ow fl at sheet membrane (pore size 100 μm and then with tubular ceramic ultrafi ltration membrane (molecular mass cut-off 5 kDa. Eff ects of transmembrane pressure and the use of a static turbulence promoter to reduce the concentration polarization near the ultrafi ltration membrane surface were examined and their positive eff ects were proven. For the fi ltration with ultrafi ltration membrane, transmembrane pressure of 3•105 Pa with 3-stage discontinuous diafi ltration was found optimal. The molecular mass distribution of purifi ed peptides using ultrafi ltration membrane was determined by a liquid chromatography–electrospray ionization quadrupole time-of-fl ight mass spectrometry setup. More than 96 % of the peptides (calculated as relative frequency from the ultrafi ltration membrane permeate had the molecular mass M≤1.7 kDa and the highest molecular mass was found to be 3.1 kDa. The decrease of allergenic property due to the tryptic digestion and membrane fi ltration was determined by an enzyme-linked immunosorbent assay and it was found to exceed 99.9 %. It was also found that the peptides purifi ed in the ultrafi ltration membrane promoted the growth of Pediococcus acidilactici HA6111-2 and they possessed antibacterial activity against Bacillus cereus.

    Cottonseed meal (CSM) is commonly used in hens’ diets to replace soybean meal (SBM). However, the molecular consequences of this substitution remains unclear. To investigate the impact of this substitution at the molecular level, iTRAQ combined with biochemical analysis was performed in Hy-Line W-36 hens supplemented with a mixed diet of CSM and SBM. Egg weight, albumen height, and Haugh unit were significantly reduced in the CSM100 group (100% crude protein of SBM replaced by CSM) compared with the SBM group (Phen diet. PMID:28813468

    Feed ingredients used in swine diets are often processed to improve nutritional value. However, (over-)processing may result in chemical reactions with amino acids (AAs) that decrease their ileal digestibility. This study aimed to determine effects of (over-)processing of soybean meal (SBM) and rapeseed meal (RSM) on post-absorptive utilization of ileal digestible AAs for retention and on body AA composition of growing pigs. Soybean meal and RSM were processed by secondary toasting in the presence of lignosulfonate to obtain processed soybean meal (pSBM) and processed rapeseed meal (pRSM). Four diets contained SBM, pSBM, RSM or pRSM as sole protein source. Two additional diets contained pSBM or pRSM and were supplemented with crystalline AA to similar standardized ileal digestible (SID) AA level as the SBM or RSM diet. These diets were used to verify that processing affected AA retention by affecting ileal AA digestibility rather than post-absorptive AA utilization. The SID AA levels of the protein sources were determined in a previous study. In total, 59 pigs were used (initial BW of 15.6±0.7 kg) of which five were used to determine initial body composition at the start of the experiment. In total, 54 pigs were fed one of six experimental diets and were slaughtered at a BW of 40 kg. The organ fraction (i.e. empty organs plus blood) and carcass were analyzed separately for N and AA content. Post-absorptive AA utilization was calculated from AA retention and SID AA intake. An interaction between diet type, comprising effects of processing and supplementing crystalline AA, and protein source was observed for CP content in the organ fraction, carcass and empty body and for nutrient retention. Processing reduced CP content and nutrient retention more for SBM than for RSM. Moreover, processing reduced (P<0.001) the lysine content in the organ fraction for both protein sources. Supplementing crystalline AA ameliorated the effect of processing on these variables. Thus

    This study was designed to assess the effects of partial substitution of roasted soybean seed with sweet potato (Ipomoea batatas) leaf meal (SPLM) on growth performances and carcass components of broiler chickens. The experiment was a completely randomized design consisting of five dietary treatments replicated four times with ten chicks each. The control diet (treatment 1, T1) contained roasted soybean seed as the major protein source without SPLM and treatment diets containing SPLM at the levels of 30 g/kg (treatment 2, T2), 60 g/kg (treatment 3, T3), 90 g/kg (treatment 4, T4) and 120 g/kg (treatment 5, T5) by partially substituting the roasted soybean seed in the control diet. The results indicated that the body weight gain in chickens reared in T1 was (pchickens reared in T1 was (pchickens fed on T1 was (pChickens fed with T2 diet had numerically higher values of slaughter, dressed carcass and breast than those reared in T4 and T5 diets. It can be concluded that the partial substitution of roasted soybean seed with sweet potato leaf might be economically feasible feeding strategy of broiler chickens in smallholder poultry farm settings.

  1. Changes in leucine kinetics during meal absorption: effects of dietary leucine availability

    Whole-body leucine and α/-ketoisocaproate (KIC) metabolism were estimated in mature dogs fed a complete meal, a meal devoid of branched-chain amino acids, and a meal devoid of all amino acids. Using a constant infusion of [4,5- 3 H]leucine and α-[1- 14 C]ketoisocaproate (KIC), combined with dietary [5,5,5- 2 H 3 ]leucine, the rate of whole-body proteolysis, protein synthesis, leucine oxidation, and interconversion leucine and KIC were estimated along with the rate of leucine absorption. Digestion of the complete meal resulted in a decrease in the rate of endogenous proteolysis, a small increase in the estimated rate of leucine entering protein, and a twofold increase in the rate of leucine oxidation. Ingestion of either the meal devoid of branched-chain amino acids or devoid of all amino acids resulted in a decrease in estimates of whole-body rates of proteolysis and protein synthesis, decreased leucine oxidation, and a decrease in the interconversion of leucine and KIC. The decrease in whole-body proteolysis was closely associated with the rise in plasma insulin concentrations following meal ingestion. Together these data suggest that the transition from tissue metabolism to anabolism is the result, at least in part, of decreased whole-body proteolysis. This meal-related decrease in proteolysis is independent of the dietary amino acid composition or content. In contrast, the rate of protein synthesis was sustained only when the meal complete in all amino acids was provided, indicating an overriding control of protein synthesis by amino acid availability

    This study evaluated the effects of replacing soybean meal (SBM) with rubber seed meal (RSM) on growth, antioxidant capacity, non-specific immune response and resistance to Aeromonas hydrophila in tilapia (Oreochromis niloticus × Oreochromis aureus). Five experimental diets were formulated with 0 (control), 10, 20, 30, and 40% RSM replacing graded levels of SBM, respectively. Fish were fed one of the five experimental diets for eight weeks, and then challenged by A. hydrophila via intraperitoneal injection and kept for seven days. Dietary RSM inclusion level up to 30% did not affect the weight gain and daily growth coefficient, whereas these were depressed by a further inclusion. Fish fed diet with 40% RSM showed the lowest serum total antioxidant capacity, lysozyme, alternative complement pathway, respiratory burst and phagocytic activities. Dietary RSM inclusion gradually depressed the post-challenge survival rate, and that was significantly lower in fish fed diet with 40% RSM compared to fish fed the control diet. Conversely, the inclusion of RSM generally increased the serum total cholesterol level, the plasma alanine aminotransferase and aspartate aminotransferase activities, and these were significantly higher in fish fed diet with 40% RSM compared to fish fed the control diet. The results indicated that RSM can be included at level up to 30% in diet for tilapia without obvious adverse effects on the growth, antioxidant capacity, non-specific immune response and resistance to A. hydrophila infection, whereas these were depressed by a further inclusion.

    CC Pizzolante

    Full Text Available ABSTRACT Bovine meat and bone meal (MBM has been used as a low-cost protein source in corn- and soybean meal-based poultry diets. However, to date, no studies investigating the effect of the dietary inclusion of MBM on the performance of Japanese quails and on egg production costs were found in literature. In this study, 600 Japanese quails in lay were distributed in a completely randomized experimental design consisting of six treatments (replacement levels of soybean meal by MBM:0, 1, 2, 3, 4, and 5% with five replicates of 20 birds each to investigate if MBM is a viable alternative to maintain or to improve the live and economic performances of these birds. Treatments consisted of a control diet, based on corn and soybean meal, with no inclusion of MBM, and diets formulated with increasing levels (1, 2, 3, 4, and 5% of MBM inclusion at the expense of soybean meal. The studied parameters were evaluated in four periods of 28 days each. Live performance parameters (egg weight, g; average egg production, %; egg weight, g; feed intake, g; feed conversion ratio per egg mass, kg/kg and per dozen eggs, dz/kg; and livability, %; egg quality parameters (proportion of egg components, yolk, albumen, eggshell %; egg specific weight, g/cm3; and economic parameter (bio-economic nutritional index were determined. Only egg weight, egg specific weight, and eggshell percentage were affected (p<0.05 by the treatments. Our results show that inclusion of bovine meat and bone meal can be added to the diet of Japanese quails in lay, causing no performance losses and promoting feed cost savings up to 5.24%.

    Full Text Available The objective was to determine the requirement of digestible protein (DP for Nile tilapia fed with diets based on soybean meal and corn. Two hundred Nile tilapia juveniles, sexually reversed, were used for a trial period of 100 days. The animals were distributed in 20 boxes of 1000 L-1 in a random design with five treatments and four replications, the boxes were connected to a water recirculation system. Five isoenergetic diets were tested with different levels of digestible protein (DP: 20, 25, 30, 35 and 40%. At the end of the experimental period were evaluated the zootechnical performance data. A quadratic effect (p < 0.05 was shown to parameters of final weight, weight gain, final length, fillet yield and visceral fat with the best points that ranged from 28.3 to 29.9% of DP. The largest area of hepatocytes was found to the lowest levels of DP in the diet (20 and 25% compared to the other levels, which were similar. Thus, Nile tilapia has adequate performance for the consumption of diets based on soybean and corn meal and the recommended level is 28.3% of PD in these conditions.

    Inappropriate feeding practice increases risk of under nutrition, illness, and mortality amongst children less than 2 years of age. The objective of this study is to assess minimum dietary diversity, meal frequency and its associated factors among infant and young children aged 6-23 months in Dangila Town, Northwest Ethiopia. A community based cross sectional study was conducted. Simple random sampling technique was used to select study participants. Interviewer administered questionnaire were used. Bivariate and multivariable logistic regression analyses was employed to identify factors associated with minimum dietary diversity and meal frequency. A total of 920 children 6-23 months were included. Proportion of children who met the minimum dietary diversity and meal frequency was 12.6 and 50.4 %, respectively. Mothers education [AOR =2.52], age of a child [AOR = 2.05], birth order of index child [AOR = 2.08], living in urban area [AOR = 2.09], having home gardening [AOR = 2.03], and media exposure [AOR = 2.74] were positively associated with dietary diversity. Moreover, age of the child [AOR = 3.03], birth order of index child [AOR = 1.58], mothers involvement in decision making [AOR = 1.51], media exposure [AOR = 2.62], and having postnatal visit [AOR = 2.30] were positively associated with meal frequency. The proportion of children who received minimum dietary diversity and meal frequency was low. Being at younger age, first birth order, and lack of media exposure affect both dietary diversity and meal frequency. Increasing mother's education, home gardening, mass media promotion and empowering women in decision making are highly recommended to increase dietary diversity and meal frequency.

    The objective of this study was to determine the effects of gossypol from cottonseed meal (CSM) on growth performance, blood biochemical profiles, and liver histopathology of ducks. A total of 900 1-d-old ducks were randomly allocated to 5 treatments with 12 pens/treatment and 15 ducks/pen. The 5 experimental diets were formulated in such a way that 0% (a corn-soybean meal basal diet, diet 1), 25% (diet 2), 50% (diet 3), 75% (diet 4), and 100% (diet 5) of protein from soybean meal were replaced with that from CSM. All diets were formulated on a digestible amino acid basis. The experiment included 2 phases, the starter phase (1 to 3 wk) where the test diets contained graded levels of CSM and the growth phase (4 to 5 wk) where birds were fed a corn-soybean basal diet to examine the recovery of ducks after CSM withdrawal. Dietary CSM and gossypol linearly (P ducks among all treatments. These results suggest that meat ducks' dietary TG and FG concentration should be lower than 928.9 and 77.2 mg/kg, respectively, during d 1 to 21 of age and that a 2-wk withdrawal of diets containing gossypol should be considered. © Poultry Science Association Inc.

The SBM is the only source of P in diets without casein, and in the diet with added casein, 1.0 to 2.4 g/kg of total dietary P was supplied by SBM as dietary level of SBM increased. The experiment consisted of a 5-d adjustment period and a 5-d total collection period with ferric oxide as a maker to indicate the initiation and termination of fecal collection. There were interactive effects of casein supplementation and total dietary P level on the apparent total tract digestibility (ATTD and retention of P (p0.05. In summary, our results demonstrate that the estimates of TTTD of P in SBM for pigs were not affected by constant casein inclusion in the basal diets.

    To confirm previously reported associations between family meal frequency and dietary intake, and to examine family cohesion as a potential mediator of this relationship. Cross-sectional observational study. Data collected at baseline via questionnaire. Randomized, controlled household weight gain prevention trial. Participants were 152 adults and 75 adolescents from 90 community households. Family meal frequency assessed with a single question. Perceived family cohesion measured by the Family Adaptability and Cohesion Evaluation Scale-III. Usual intake of targeted food items assessed with modified food frequency questionnaire. Hierarchical linear regression with mediation analysis. Statistical significance set at α-level .05. Family meal frequency was associated with intake of fruits and vegetables in adults, and sweets and sugar-sweetened beverages in adolescents. Family meal frequency was positively correlated with perceived family cohesion (r = 0.41, P family cohesion was observed for family meal frequency and sweets intake in adolescents. Results suggest that family cohesion is not a consistent mediator of relationship between family meal frequency and individual dietary intake. Future studies should assess additional plausible mediators of this relationship in order to better understand the effect of family meals on dietary intake.

    Full Text Available The present study was carried out in order to investigate the effects of the mannanoligosaccharide (MOS and fructooligosaccharide (FOS on sharpsnout seabream, Diplodus puntazzo in the context of partial fish meal substitution by soybean meal. One-hundred-forty-four sharpsnout seabream of about 100 g initial body weight were randomly divided in 12 experimental tanks (180 litre each. Testing conditions included 12 fish per tank, with triplicate tanks for treatment. The experimental period lasted 114 days. Average water temperature was 21.9±1.6°C, salinity was 30.0‰ and pH ranged from 7 to 8. Four isonitrogenous-isolipidic diets were tested: a control diet (FM with fish meal as the sole protein source; a second diet (SBM with approximately 40% of the protein supplied by soybean meal. The remaining two diets were formulated adding 8 g of MOS and FOS per kg of the SBM diet respectively. Average final weight, specific growth rate, feed conversion ratio and protein efficiency ratio remained unaffected by partial fish meal substitution and by MOS or FOS supplementation. Also apparent digestibility coefficients values for organic matter, protein, lipid and energy were not significantly affected by dietary treatment.

    To summarize the research literature on associations between family meal frequency and dietary outcomes as well as weight status across the lifespan. Reviewed literature of family or shared meals with dietary and weight outcomes in youth, adults, and older adults. Across the lifespan, eating with others, particularly family, is associated with healthier dietary outcomes. Among children and adolescents, these findings appear to be consistent for both boys and girls, whereas mixed findings are seen by gender for adult men and women. The findings of associations between family or shared meals and weight outcomes across the lifespan are less consistent and more complicated than those of dietary outcomes. Now is the time for the field to improve understanding of the mechanisms involved in the positive associations seen with family meal frequency, and to move forward with implementing interventions aimed at increasing the frequency of, and improving the quality of, food served at family meals, and evaluating their impact. Given the more limited findings of associations between family or shared meals and weight outcomes, capitalizing on the positive benefits of family and shared meals while addressing the types of foods served, portion sizes, and other potential mechanisms may have a significant impact on obesity prevention and reduction. Future research recommendations are provided. Copyright © 2014 Society for Nutrition Education and Behavior. Published by Elsevier Inc. All rights reserved.

    Little is known about the healthfulness of foods offered at family meals or the relationship between the food's healthfulness and child overall dietary intake. This exploratory study uses a newly developed Healthfulness of Meal Index to examine the association between the healthfulness of foods served at family dinners and child dietary intake. Direct observational, cross-sectional study. Primarily low-income, minority families (n=120) video recorded 8 days of family dinners and completed a corresponding meal screener. Dietary recalls were completed on the target child (6 to 12 years old). The Healthfulness of Meal Index was used to measure meal healthfulness and included component scores for whole fruit, 100% juice, vegetables, dark green vegetables, dairy, protein, added sugars, and high-sodium foods. Child dietary intake measured by three 24-hour dietary recalls. Linear regression models estimated the association between the healthfulness of foods served at dinner meals and overall child HEI. The majority of coded meals included foods from protein and high-sodium components; more than half included foods from dairy and vegetable components. Nearly half of the meals had an added-sugar component food (eg, soda or dessert). Few meals served foods from fruit, 100% juice, or dark green vegetable components. Many components served at family dinner meals were significantly associated with child daily intake of those same foods (ie, dark green vegetable, non-dark green vegetables, dairy, and added sugars). The Healthfulness of Meal Index total score was significantly associated with child HEI score. This study represents the first report of a new methodology to collect data of foods served at family dinners. Results indicated a significant association between the majority of components served at family dinner meals and child overall dietary intake. Validation of the Healthfulness of Meal Index and video-recorded family meal methodology is needed to strengthen these

However, little is known about the structural characteristics and interpersonal dynamics of family meals that may help to inform why family meals are protective for youth. The current mixed methods, cross-sectional study conducted in 2010–2011 includes adolescents and parents who participated in two linked population-based studies. Participants included 40 parents (91.5% female) and adolescents (57.5% female) from the Minneapolis/St. Paul area participating in EAT 2010 and F-EAT. The structural (e.g. length of the meal, types of foods served) and interpersonal characteristics (e.g., communication, emotion/affect management) of family meals were described and associations between interpersonal dynamics at family meals and adolescent body mass index (BMI) and dietary intake were examined via direct observational methods. Families were video-recorded during two mealtimes in their homes. Results indicated that family meals were approximately 20 minutes in length, included multiple family members, were typically served family style (70%) and occurred in the kitchen 62% of the time and 38% of the time in another room (e.g., family room, office). Additionally, significant associations were found between positive interpersonal dynamics (i.e., communication, affect management, interpersonal involvement, overall family functioning) at family meals and lower adolescent BMI and higher vegetable intake. These findings add to the growing body of literature on family meals by providing a better understanding of what is happening at family meals in order to inform obesity prevention studies and recommendations for providers working with families of youth.

    Waste materials have a strong potential in the bioremediation of oil-contaminated sites, because of their richness in nutrients and their economical feasibility. We used sewage sludge, soybean meal, and wheat straw to biostimulate oil degradation in a heavily contaminated desert soil. While oil degradation was assessed by following the produced CO2 and by using gas chromatography–mass spectrometry (GC–MS), shifts in bacterial community composition were monitored using illumina MiSeq. The addition of sewage sludge and wheat straw to the desert soil stimulated the respiration activities to reach 3.2–3.4 times higher than in the untreated soil, whereas the addition of soybean meal resulted in an insignificant change in the produced CO2, given the high respiration activities of the soybean meal alone. GC–MS analysis revealed that the addition of sewage sludge and wheat straw resulted in 1.7–1.8 fold increase in the degraded C14 to C30 alkanes, compared to only 1.3 fold increase in the case of soybean meal addition. The degradation of ≥90% of the C14 to C30 alkanes was measured in the soils treated with sewage sludge and wheat straw. MiSeq sequencing revealed that the majority (76.5–86.4% of total sequences) of acquired sequences from the untreated soil belonged to Alphaproteobacteria, Gammaproteobacteria, and Firmicutes. Multivariate analysis of operational taxonomic units placed the bacterial communities of the soils after the treatments in separate clusters (ANOSIM R = 0.66, P = 0.0001). The most remarkable shift in bacterial communities was in the wheat straw treatment, where 95–98% of the total sequences were affiliated to Bacilli. We conclude that sewage sludge and wheat straw are useful biostimulating agents for the cleanup of oil-contaminated desert soils. PMID:26973618

    An experiment was conducted to measure the effect of adding soybean oil to soybean meal (SBM) and soy protein concentrate (SPC) on apparent (AID) and standardized (SID) ileal digestibility of CP and AA by growing pigs. A second objective was to compare AID and SID of AA in a new high-protein variety of full fat soybeans (FFSB) to values obtained in other soybean products. Commercial sources of FFSB (FFSB-CV), SBM, and SPC, and of a new high-protein variety of FFSB (FFSB-HP) were used in the experiment. Four diets were prepared using each soybean product as the sole source of CP and AA in 1 diet. Two additional diets were formulated by adding soybean oil (7.55 and 7.35%, respectively) to the diets containing SBM and SPC. A nitrogen-free diet was also used to measure basal endogenous losses of CP and AA. The 2 sources of FFSB were extruded at 150 degrees C before being used in the experiment. Seven growing barrows (initial BW = 26.2 kg) were prepared with a T-cannula in the distal ileum and allotted to a 7 x 7 Latin square design. Ileal digesta were collected from the pigs on d 6 and 7 of each period. All digesta samples were lyophilized and analyzed for DM, CP, AA, and chromium, and values for AID and SID of CP and AA were calculated. The addition of oil improved (P oil and SPC, but these values were lower (P oil. In conclusion, the addition of oil improved the SID of most AA in SBM and SPC fed to growing pigs, and the SID of AA in FFSB-HP were greater than in SBM and similar to the SID of AA in SBM with oil and in SPC.

    Background Little is known about the healthfulness of foods offered at family meals or the relationship between the food’s healthfulness and child overall dietary intake. Objective This exploratory study uses a newly-developed Healthfulness of Meal (HOM) index to examine the association between the healthfulness of foods served at family dinners and child dietary intake. Design Direct observational, cross-sectional study. Participants/setting Primarily low-income, minority families (n=120) video-recorded 8 days of family dinners and completed a corresponding meal screener. Dietary recalls were completed on the target child (6–12 years old). The HOM index was used to measure meal healthfulness and included component scores for whole fruit, 100% juice, vegetables, dark green vegetables, dairy, protein, added sugars, and high sodium foods. Main outcome measures Child dietary intake measured by three 24-hour dietary recalls. Statistical analyses performed Linear regression models estimated the association between the foods served at dinner meals and overall child dietary intake. Results The majority of coded meals included foods from protein and high sodium components; over half included foods from dairy and vegetable components. Nearly half of the meals had an added sugar component food (e.g., soda, dessert). Few meals served foods from fruit, 100% juice, or dark green vegetable components. Many components served at family dinner meals were significantly associated with child daily intake of those same foods (i.e., dark green, non-dark green vegetables, dairy, and added sugars). The HOM index total score was significantly associated with child HEI score. Conclusions This study represents the first report of a new methodology to collect data of foods served at family dinners. Results indicated a significant association between the majority of components served at family dinner meals and child overall dietary intake. Validation of the HOM index and video

    Following disparity of earlier results, this study tested the performance of African catfish Clarias gariepinus fed dried brewer's yeast slurry meal (DBYM) based diets. Fingerlings of C. gariepinus with pooled mean initial weight of 1.58 ± 0.01 g were stocked in hapas (1 m × 1 m × 1 m) immersed in an earthen pond at a density of 15 fish per cage. Five diets with increasing substitution of soybean meal with 25%, 50%, 75%, and 100% of dried brewer's yeast and a control without dried brewer's yeast (0% substitution) were evaluated for 8 weeks. Palatability of diets reduced with increasing levels of DBYM. Growth and utilization parameters such as weight gain, feed conversion ratio, protein efficiency ratio, and specific growth rate differed significantly ( p meal with DBYM in C. gariepinus feed is between 1% and 14% of dry matter.

    This study evaluated wheat grain which was treated with xylose in aqueous Ca-Mg lignosulphonate solution at elevated temperatures (WeiPass®) in order to reduce ruminal degradation of starch and crude protein. The two tested isoenergetic and isonitrogenous diets contained on dry matter (DM) basis either 16% maize grain and 6.4% soybean meal (Diet CON) or 17.8% xylose-treated wheat and 4.6% soybean meal (Diet Wheat). Thirty-six German Holstein dairy cows were assigned to one of the two groups according to parity, body weight after calving, and milk yield during the previous lactation. Data collection started at 21 d before the expected calving date until 120 d in milk. The average of DM intake, energy-corrected milk (ECM) yield, and milk fat and protein yields (all given as kg/d) were 18.9, 28.7, 1.25, and 1.02 for Diet CON and 19.3, 32.5, 1.36, and 1.11 for Diet Wheat, respectively. Only ECM and milk protein yields were greater (p < 0.05) for cows receiving Diet Wheat. In conclusion, the xylose-treated wheat grain can replace maize grain and part of soybean meal in diets for lactating dairy cows and may be an alternative feedstuff depending on overall ration composition and availability and costs of grain sources.

    Isoflavone in soybean and its products have numerous beneficial health effects. A number of clinical studies have demonstrated that dietary soy isoflavone can relieve menopausal symptoms, lower risks of breast cancer, and lower cholesterol and glucose. Among the various effects of isoflavone, the role of cholesterol and glucose reduction seems to be well documented; however, other effects such as reproductive hormones were inconclusive and inconsistent. The main objective of the present study was to investigate the effects of six-month dietary traditional fermented soybean intake on BMI, reproductive hormones, lipids, and glucose among postmenopausal women. Subjects were women with their last menstrual period occurring at least 12 months prior to selection by interview and health screening from Baan Tham Village, Phayao Province, Thailand. A total of 60 women were divided into 2 groups: experimental group (n=31) and reference group (n=29). The experimental group was permitted to continue their usual diet, and supplemented with fermented soybean for 6 months. The fermented soybean provided approximately 60 mg of isoflavone per day. The remarkable findings were that dietary fermented soybean had favorable effects on progesterone and cholesterol, but had no effects on estradiol, glucose, and triglycerides. Although estradiol and glucose in the experimental group did not change, a decrease of estradiol and an increase of glucose were found in the reference group. Our results, therefore, suggest that fermented soybean may have beneficial effects on reproductive hormones and cholesterol, and they would be warrant further detail investigations.

    To assess the effect of dietary fiber on glucose tolerance four different meals of varying fiber content but identical protein fat and carbohydrate content were fed to eight healthy men aged 22 to 45. Each meal provided 75 g of carbohydrate as liquid glucose formula, as brown rice, pinto beans, or All Bran. The mean plasma glucose and insulin responses were highest following the formula, and least for All Bran and pinto beans. Rice produced nearly as great a rise in insulin and glucose as did the formula. The rank of each meal by content of neutral detergent fiber was nearly the inverse of the rank by magnitude of the insulin response evoked, fiber content being greatest in All Bran (18 g) and pinto beans (16.2 g), low in rice (2.8 g) and absent from the formula. It was concluded that dietary fiber dampened the insulin response to a high carbohydrate meal.

    Insufficient quantities, frequencies, and inadequate quality of complementary feedings have a negative effect on child health and growth, especially in the first two years of life. Therefore, the aim of this study was to assess the minimum dietary diversity, meal frequency and its associated factors among infants and young children aged 6-23 months at Dabat District, northwest, Ethiopia. A community- based cross-sectional study was conducted from February 15 to March 10, 2016. The simple random sampling method was used to select study participants. An interviewer- administered structured questionnaire was used to collect data. Both Crude and Adjusted Odds Ratio with the corresponding 95% confidence interval were calculated to show the strength of association. In the multivariable analysis, variables with less than 0.05 P-value were considered statistically significant. The proportion of children who met the minimum dietary diversity and meal frequency were 17% (95% CI: 14.9, 19.4%) and 72.2% (95% CL: 69.3, 75%), respectively. Satisfactory media exposure (AOR = 2.79; 95% CI: 1.74, 4.47), postnatal care visits (AOR = 1.96; 95% CI: 1.32, 2.88), participation in child growth and monitoring follow ups (AOR = 1.65; 95% CI: 1.14, 2.39), age of children (AOR = 2.34; 95% CI: 1.33, 4.11) and age of mothers (AOR = 1.89; 95% CI: 1.09, 3.27) were positively associated with dietary diversity. Similarly, age of children (AOR = 2.38; 95% CI: 1.56, 3.65), household wealth status (AOR = 1.84; 95% CI: 1.27, 2.68), residence (AOR = 3.02; 95% CI: 1.41, 6.48), sources of information (AOR = 1.72; 95% CI:1.14, 2.59) and participation in child growth monitoring folow ups (AOR = 1.57; 95% CI: 1.13, 2.19) were significantly associated with meal frequency. In this study, the proportion of children who received the minimum dietary diversity and meal frequency were low.

    (i) To examine associations between young adults' meal routines and practices (e.g. food preparation, meal skipping, eating on the run) and key dietary indicators (fruit/vegetable, fast-food and sugar-sweetened beverage intakes) and (ii) to develop indices of protective and risky meal practices most strongly associated with diet. Cross-sectional survey. Minneapolis/St. Paul metropolitan area, Minnesota (USA). A diverse sample of community college and public university students (n 1013). Meal routines and practices most strongly associated with healthy dietary patterns were related to home food preparation (i.e. preparing meals at home, preparing meals with vegetables) and meal regularity (i.e. routine consumption of evening meals and breakfast). In contrast, factors most strongly associated with poor dietary patterns included eating on the run, using media while eating and purchasing foods/beverages on campus. A Protective Factors Index, summing selected protective meal routines and practices, was positively associated with fruit/vegetable consumption and negatively associated with fast-food and sugar-sweetened beverage consumption (PMeal routines and practices were significantly associated with young adults' dietary patterns, suggesting that ways in which individuals structure mealtimes and contextual characteristics of eating likely influence food choice. Thus, in addition to considering specific food choices, it also may be important to consider the context of mealtimes in developing dietary messaging and guidelines.

    Full Text Available A 77-day feeding trial was designed in order to assess the effect of partial or total replacement of soybean meal by hazelnut meal (HNM on feed intake, growth performance, nutrient utilization and body composition of rainbow trout (initial mean body weight: 80.0±3.5 g in seawater conditions. A control and three experimental diets were formulated in which soybean meal level (25.5% in the control diet was replaced by hazelnut meal at 39.2 (HN 39, 78.4 (HN 78 and 100% (HN 100 to provide 44% crude protein and 20% crude lipid diets. Diets were fed to 125 rainbow trout to apparent satiation by hand twice daily at 09.00 and 16.00 hours under natural photoperiod conditions. At the end of the feeding trial, fish of all groups almost tripled their body weight and no significant difference (P>0.05 was revealed in final weight or specific growth rate between treatments. However, feed conversion ratio (FCR of the HN100 group was significantly higher than other treatments (P<0.05. There was a slightly decreasing trend in protein efficiency ratio (PER and net protein utilization (NPU with increasing level of dietary hazelnut meal, but it was only significant in groups of fish fed HN100. All groups of fish displayed similar carcass and muscle compositions. According to the results of the present study, it can be stated that hazelnut meal can replace soybean meal at up to 200 g kg-1 in grow-out diets of rainbow trout without any detrimental effects on growth performance.

    Partial or complete replacement of fish meal (FM) with fermented soybean meal (FSM) was examined in Macrobrachium nipponense over an 8-week growth trial. Growth and immune characteristics were evaluated. Fermented soybean meal replaced 0 (FM, control), 25% (R25), 50% (R50), 75% (R75), or 100% of the FM (R100) in five isocaloric and isonitrogenous diets. Each diet was fed to juvenile prawns (mean weight, 0.103 ± 0.0009 g) twice daily to apparent satiation in five replicates. Weight gain and specific growth rate of M. nipponense were significantly higher in prawns fed the R25 diet than that of prawns fed the FM diet. No significant differences were observed among the other treatments. Total hemocyte count and hemolymph phagocytic activity decreased as the proportion of FSM increased. Total antioxidant activity competence and malondialdehyde level in the hepatopancreas were highest in prawns fed the R100 diet. mRNA levels of the antioxidant genes Cu-Zn superoxide dismutase and catalase, heat shock cognate protein 70, and heat shock protein 90 were significantly differentially regulated in the prawn hepatopancreas. In addition, percent mortality increased after challenge with live Aeromonas hydrophila. Percent mortality of prawns fed the R100 diet was significantly higher than that of prawns fed the FM and R25 diets. These findings demonstrate that (1) M. nipponense growth performance was not affected by including a high proportion of FSM in the diet, and the best growth performance was obtained when 25% of the FM was replaced with FSM; (2) nonspecific immunity was impaired when all of the FM was replaced with FSM.

    The potential of enzyme-treated soybean meal powder (HP310) as fish meal alternative in diets for rainbow trout weighing 1.17 ± 0.3 g was evaluated for 60 days. Fish meal was replaced with HP310 at 25%, 50%, 75% and 100% of experimental diets. A control group was also considered. The results showed that diets containing 75% and 100% HP310 had significantly higher feed conversion ratio and lower feed intake, weight gain and specific growth rate compared to fish feed diets containing higher levels of fish protein ingredients (p replacement levels of diet (p > 0.05). However increasing in level of HP310 in the diet caused a significant increase of the white blood cells (p replaced by HP310 showed the highest values of ash and moisture content among the diets and showed significantly different levels when compared with the control and other feeding treatments (p < 0.05).

    Full Text Available Changes in development and in physiological parameters of fingerlings of the pacu (Piaractus mesopotamicus fed on diets with high levels of integral crude, extruded, toasted soybean and soybean meal were assessed. The products were evaluated in practical diets for pacu, initially weighing 70 ± 2.19 g, during 82 days. Nine treatments were studied in a 2 × 4 + 1 factorial scheme which corresponded to two fish meal protein replacement levels (50 and 100% and four soybean products, plus control (100% of fish meal - FM. Development, organosomatic indexes and physiological parameters were evaluated. No differences were reported with regard to weight gain, food intake, food conversion, protein efficiency ratio and specific growth rate. A significant interaction was registered for plasma protein between the evaluated ingredients and replacement percentage of fish meal protein. Results showed that the ingredients assessed did not affect the development of the pacu when compared to fish fed on control diet. Protein retention was favored when toasted soybean and when 50% of the diet’s protein fraction from fish meal were employed.

    Full Text Available Quail egg production has experienced a steep rise in the last decade. Nutrition is the main factor affecting productive potential in the poultry industry, as appropriate nutritional management is necessary to ensure the maintenance of optimal physical conditions, growth and the production of high quality products. Meat and bone meal (MBM has often been used in the poultry industry as an alternative and cost-effective source of protein in partial replacement of corn and soybean meal. However, there have been no studies to date that have investigated the effect of dietary MBM on the performance of quail or on the costs of production in the starter phase. This is particularly important considering that this phase is characterized by large investments by producers, without immediate economic return. In this study, we investigated whether partial replacement of soybean meal (SBM by meat and bone meal (MBM in the diet of Japanese quail during the starter phase is a viable alternative that would maintain or improve their productive and economic performance. Our results show that the inclusion of MBM in the diet of quail reduces feeding costs by up to 6% without impairing productive performance.

    Full Text Available The present study aimed to assess the effect of dietary substitution of soybean meal (SBM with dehulled-micronized faba bean (Vicia faba var. minor in guinea fowl broilers on their growth traits, carcass quality, and meat fatty acids composition. In this trial, 120 day-old guinea fowl keets were randomly assigned to two treatments which were fed from hatch to 12 weeks of age. Birds were fed two wheat middlings-based diets comprising of a control treatment which contained SBM (78.3 g/kg and a test diet containing dehulled-micronized faba bean (130 g/kg as the main protein source. Substituting SBM with faba bean had no adverse effect on growth traits, dressing percentage, or breast and thigh muscles relative weight of the guinea fowls. Conversely, a decrease (p<0.05 of abdominal fat was found in guinea fowls fed the faba bean-diet. Breast muscle of birds fed faba bean had higher L* score (p<0.05 and water-holding capacity (p<0.05 than the SBM control diet. Meat from guinea fowls fed faba bean had less total lipids (p<0.05 and cholesterol (p<0.01, and higher concentrations of phospholipids (p<0.01. Feeding faba bean increased polyunsaturated fatty acid concentrations in breast meat and decreased the saturated fatty acid levels. Moreover, dietary faba bean improved the atherogenic and thrombogenic indexes in guinea fowl breast meat. Results indicated that substitution of SBM with faba bean meal in guinea fowl diet can improve carcass qualitative traits, enhancing also meat lipid profile without negatively affecting growth performance.

    Full Text Available This study was aimed to explore the nutrient content, relative feed values (RFV and in vitro true digestibilities (IVTD of wheat straw and soybean straw pellets produced with the addition of molasses, guar meal and sepiolite. In this experiment, 16 groups were created for 2 different straws (wheat/soybean straws, 2 different sepiolite applications (available/not available and 4 different applications (control, guar meal, molasses, guar meal+molasses in accordance with the 2×2×4 factorial design. A Daisy incubator was used to determine the IVTD of the feeds. According to the results, molasses and guar meal increased the RFV of soybean straws, while molasses and guar meal treatments and sepiolite did not affect the RFV of wheat straws. It was observed that sepiolite increased the RFV’s of soybean straw for guar meal and guar meal+molasses. The higher IVTD’s were found for guar meal (without sepiolite treatment of soybean straw and guar meal (with sepiolite treatment of wheat straw. Molasses and guar meal addition to wheat and soybean straws improved the crude protein contents. In conclusion, straw pelleting can be used as an alternative forage conservation method to close the gap in forage supply during the winter.

    Daily restricted access to food leads to the development of food anticipatory activity and metabolism, which depends upon an as yet unidentified food-entrainable oscillator(s). A premeal anticipatory peak in circulating hormones, including corticosterone is also elicited by daily restricted feeding. High-fat feeding is associated with elevated levels of corticosterone with disrupted circadian rhythms and a failure to develop robust meal anticipation. It is not clear whether the disrupted corticosterone rhythm, resulting from high-fat feeding contributes to attenuated meal anticipation in high-fat fed rats. Our aim was to better characterize meal anticipation in rats fed a low- or high-fat diet, and to better understand the role of corticosterone in this process. To this end, we utilized behavioral observations, hypothalamic c-Fos expression, and indirect calorimetry to assess meal entrainment. We also used the glucocorticoid receptor antagonist, RU486, to dissect out the role of corticosterone in meal anticipation in rats given daily access to a meal with different fat content. Restricted access to a low-fat diet led to robust meal anticipation, as well as entrainment of hypothalamic c-Fos expression, metabolism, and circulating corticosterone. These measures were significantly attenuated in response to a high-fat diet, and animals on this diet exhibited a postanticipatory rise in corticosterone. Interestingly, antagonism of glucocorticoid activity using RU486 attenuated meal anticipation in low-fat fed rats, but promoted meal anticipation in high-fat-fed rats. These findings suggest an important role for corticosterone in the regulation of meal anticipation in a manner dependent upon dietary fat content.

    Objective An experiment was conducted to evaluate effects of inclusion level of palm kernel meal (PKM) and adaptation duration on the digestible energy (DE) and apparent total tract digestibility (ATTD) of chemical constituents in diets fed to growing-finishing pigs. Methods Thirty crossbred barrows (Duroc×Landrace×Large White) with an average initial body weight of 85.0±2.1 kg were fed 5 diets in a completely randomized design. The diets included a corn-soybean meal basal diet and 4 additional diets in which corn and soybean meal were partly replaced by 10%, 20%, 30%, or 40% PKM. After 7 d of adaptation to the experimental diets, feces were collected from d 8 to 12, d 15 to 19, d 22 to 26, and d 29 to 33, respectively. Results The DE and ATTD of gross energy (GE), dry matter (DM), ash, organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), and crude protein (CP) in diets decreased linearly as the dietary PKM increased within each adaptation duration (p 0.05). Considering a stable determination, 21 days of adaptation to a diet containing 19.5% PKM is needed in pigs and a longer adaptation time is recommended as dietary PKM increases. PMID:28920411

    DP-3Ø5423-1 (305423) is a genetically modified soybean that was produced by biolistic insertion of the gm-fad2-1 gene fragment and gm-hra genes into the germline of soybean seeds. Expression of gm-fad2-1 results in greater concentrations of oleic acid (18:1) by suppressing expression of the endogenous FAD2-1 gene, which encodes an n-6 fatty acid desaturase enzyme that catalyzes desaturation of 18:1 to linoleic acid (18:2). The GM-HRA protein expressed by the gm-hra gene is a modified version of the soybean acetolactate synthase enzyme that is used as a selectable marker during transformation. A 42-d feeding trial was conducted with broiler chickens to compare the nutritional performance of 305423 soybeans with nontransgenic soybeans. Diets were prepared using processed fractions (meal, hulls, and oil) from 305423 soybean plants. For comparison, additional diets were produced with soybean fractions obtained from a nontransgenic near-isoline (control) and nontransgenic commercial Pioneer brand varieties (93B86, 93B15, and 93M40). Diets were fed to Ross x Cobb broilers (n = 120/group, 50% male and 50% female) in 3 phases. Starter, grower, and finisher diets contained 26.5, 23, and 21.5% soybean meal, respectively. Soybean hulls and oil were added at 1.0 and 0.5%, respectively, across all diets in each phase. No statistically significant differences were observed in growth performance (BW, mortality, feed efficiency), organ yield (liver and kidney), or carcass yield (breast, thigh, leg, wing, and abdominal fat) variables between broilers consuming diets prepared with isolated fractions from 305423 or near-isoline control soybean. Additionally, all performance and carcass variables from control and 305423 soybean treatment groups fell within tolerance intervals constructed for each response variable using data from broilers fed diets prepared with reference soybean fractions. Based on the results from this study, it was concluded that 305423 soybeans were nutritionally

    Full Text Available The objective was to study the effects of partial replacement of soybean meal (SBM with xylose-treated SBM (XSBM as a source of rumen undegradable protein (RUP in the starter concentrate of calves on performance, health status and selected blood metabolites. Twenty-one female Holstein dairy calves (body weight=39.6±2.3 kg were randomly assigned to 3 groups (n=7 each: i starter concentrate with 25% SBM [control (CTR]; ii starter concentrate with 17.5% SBM +7.5% XSBM (7.5XSBM; and iii starter concentrate with 12.5% SBM+12.5% XSBM (12.5XSBM. Calves received 2 L of milk twice daily, with ad libitum access to starter concentrates from d 4 until weaning (d 56. Performance and health status were recorded throughout the experiment. Blood samples collected on d 4, 35 and 56 were assayed for concentrations of glucose, total protein (TP, and plasma urea nitrogen (PUN. Starter intake (560, 400, and 420 g/d for CTR, 7.5XSBM, and 12.5XSBM, respectively, average daily gain (0.67, 0.6 and 0.57 kg/d, and feed to gain ratio (0.83, 0.67, and 0.74 were affected by treatments (P<0.05. Hearth girth, height at withers, body length, rectal temperature, faecal score, and respiratory score did not differ among treatments. Mean plasma glucose and TP were not affected by treatments, whereas PUN in the 12.5XSBM group was lower than in the other groups (P<0.05. In conclusion, the present results showed that partial replacement of SBM by XSBM may improve efficiency of dietary protein utilisation in pre-weaned calves, which warrants further studies.

Consumption of peanuts as a snack tended to strengthen dietary compensation compared to peanuts or other loads with a meal. Conclusions. Inclusion of an energy-dense food as a snack or meal component had comparable influence on AR and EI. Peanuts tended to elicit stronger dietary compensation when consumed as a snack versus with a meal. If substantiated, this latter observation suggests that properties other than those controlled here (energy, macronutrient content, and volume modify AR and EI.

    2003-06-01

    Full Text Available This article analyzes the effectiveness of hedging Brazilian soy oil, soy meal, and soybeans in the Chicago Board of Trade (CBOT and in the Brazilian Commodities and Futures Exchange (BM&F to reduce the risk of financial loss due to commodity price fluctuations. The econometric results show that a cross-hedging strategy using the BM&F soybean futures contract is an instrument of low effectiveness for managing soy oil and soy meal price risk. Despite low effectiveness, the estimates demonstrate total advantage for soy meal hedging operations using CBOT soy meal futures contracts rather than cross-hedging using BM&F soybean futures contracts. With some exceptions, the results are also more favorable for hedging soy oil with soy oil futures contracts at the CBOT rather than cross hedging with soybeans at the BM&F. Conversely, Brazilian traders hedging soybeans receive more effective risk protection by trading soybean futures contracts at the BM&F than by trading soybean futures contracts at the CBOT.

    Two hundred and sixteen 28-wk-old Hy-line laying hens were randomly distributed to three dietary treatments and fed 1of 3 diets containing 8% soybean oil, fish oil, or coconut oil from 28 to 47 wk of age to investigate comparative effect of dietary soybean oil, fish oil, and coconut oil on the performance, egg quality and blood malondialdehyde (MDA), aspartate transaminase (AST) and uric acid (UA). Hens fed fish oil showed poor performance compared with soybean oil or coconut oil, and especially egg weight throughout the trial was significantly and consistently decreased (P oil. Unexpectedly, shell reflectivity throughout the majority of the trial was consistently and significantly higher (P oil than that when fed soybean oil or coconut oil. Dietary treatments affected (P oil treatment was higher (P oil group. Albumen height, Haugh unit and yolk color were influenced by dietary treatments only at 1 or 2 time points. However, average albumen height and Haugh unit in fish oil treatment were higher (P soybean oil or coconut oil treatments and average yolk color in coconut oil treatment was higher (P soybean oil group. Serum MDA, AST and UA concentrations were increased (P oil during the majority of the first 2 mo of the trial. These data suggested that the inclusion of fish oil into feed may reduce the performance of laying hens, especially the egg weight, decrease the intensity of egg brown color and increase blood MDA, AST and UA levels compared with soybean oil or coconut oil. As a result, hens fed fish oil may lay smaller, longer and lighter-brown eggs whereas those fed coconut oil produce blunter and darker-brown eggs relative to soybean oil.

    Sixty rural women with age varying between 25 and 35 were selected randomly to determine the role of dietary factors on bioavailability of iron in their diets. Food samples of selected subjects were collected for three major meals i.e. breakfast, lunch and dinner for three consecutive days. The samples were analyzed for meal constituents associated with iron absorption as well as for total and dialyzable iron. Based on dietary characteristics, the diets of the farm women were in the class of intermediate diets as per FAO/WHO classification with iron bioavailability of 8.11 %. The statistical analysis revealed that the meal constituents which were found to influence iron absorption positively were ascorbic acid and β-carotene in breakfast and only β-carotene in dinner. The meal constituents which affected iron absorption negatively were zinc and calcium in breakfast as well as lunch and phytates and NDF in dinner, however, polyphenols present in the meals of the subjects did not show any relationship with iron absorption.

    Full Text Available The main purpose of this study is to evaluate the effect of total replacement of soybean meal and corn with triticale and faba bean or field pea on rumen fermentation, protozoa counts, and gas production of lactating ewes. A total of 30 Sicilo-Sarde ewes were randomly allocated into three groups and were fed 1.8 kg drymatter of oat hay plus 500 g of one of three concentrates: the first concentrate (CS was mainly composed of soybean meal, corn, and barley; the second (TFB was formed by triticale and faba bean; and the third (TFP was composed of triticale and field pea. The type of concentrate did not affect ruminal pH or ammonia nitrogen concentration (P  >  0.05. The individual concentrations of volatile fatty acids showed a significant interaction between the type of concentrate and sampling time (P  <  0.05, except for Butyric and Isobutyric acids. Within a post-feeding time, the pattern of evolution of total volatile fatty, acetic, and propionic acids differed significantly at 2 h post feeding (P  <  0.05, while butyric and valeric acid changed at 0 and 4 h post feeding. The type of concentrate affected the total number of ciliate protozoa and the Isotricha species (P  <  0.05, whereas Entodinium, Ophryoscolex, and Polyplastron were similar among concentrates (P  >  0.05. The cumulative gas production from the in vitro fermentation, the time of incubation, and their interaction was affected by concentrate (P  <  0.001. The substitution of soybean meal and corn in the concentrate with faba bean or field peas and triticale might maintain rumen parameters of dairy ewes.

    The last decade of research has suggested that family meals play an important role in promoting healthful dietary intake in youth. However, little is known about the structural characteristics and interpersonal dynamics of family meals that might help to inform why family meals are protective for youth. The current mixed methods, cross-sectional study conducted in 2010-2011 includes adolescents and parents who participated in two linked population-based studies. Participants included 40 parents (91.5% female) and adolescents (57.5% female) from the Minneapolis/St Paul, MN, area participating in EAT (Eating and Activity Among Teens) 2010 and F-EAT (Families and Eating and Activity Among Teens). The structural (eg, length of the meal, types of foods served) and interpersonal characteristics (eg, communication, emotion/affect management) of family meals were described, and associations between interpersonal dynamics at family meals and adolescent body mass index and dietary intake were examined via direct observational methods. Families were videorecorded during two mealtimes in their homes. Results indicated that family meals were approximately 20 minutes in length, included multiple family members, were typically served family style (70%), and occurred in the kitchen 62% of the time and 38% of the time in another room (eg, family room, office). In addition, significant associations were found between positive interpersonal dynamics (ie, communication, affect management, interpersonal involvement, overall family functioning) at family meals and lower adolescent body mass index and higher vegetable intake. These findings add to the growing body of literature on family meals by providing a better understanding of what is happening at family meals in order to inform obesity-prevention studies and recommendations for providers working with families of youth.

    The aim of this study was to evaluate daily menus at students' restaurants and to report dietary habits and other health-related behaviour of Croatian university students (n=2075) according to gender. A specially designed self-administered questionnaire was used. One hundred and twenty daily menus were chosen by random sampling, and the nutritive value was calculated using food composition tables. Daily menus on average provide an adequate amount of energy, protein and most micronutrients: 88.2% of daily menus provide a balanced intake of protein, fat and carbohydrates, 22.5% of daily menus provide more than 300 mg of cholesterol, and 58.8% have more than 25 g dietary fibre. On average, students had 2.4 meals and 1.3 snacks per day. Breakfast was the most often skipped meal. Red meat, cereals and fast food were consumed more often by males (Pconsumption it was vice versa: 88.9 and 84.8% of males and females, respectively. A total of 80.4% of students were well nourished. This study showed that meals offered at students' restaurants are adequate. Dietary and other health-related behaviour differed according to gender. Clustering of some behaviours was observed.

    Increasing demand, uncertain availability and high price of fish oil with the expansion of aquaculture made it essential to search alternative lipid sources. Vegetable oil has been proved to be the best candidate for the replacement of fish oil in aquafeeds. However, this replacement especially in high level potentially has some negative effects on fish. The present study was conducted to investigate the growth performance, anti-oxidative and inflammatory responses of large yellow croaker to replacement of dietary fish oil by soybean oil. Three isonitrogenous (46% crude protein) and isolipidic (13% crude lipids) diets were formulated to feed fish (initial body weight: 36.80 ± 0.39 g) for 12 weeks. The control diet was designed to contain 6.5% of fish oil, and named as FO. On the basis of the control diet, the fish oil was 50% and 100% replaced by soybean oil, and these two diets were named as FS and SO, respectively. Results showed that the specific growth rate significantly decreased in the SO group. Crude lipid contents in muscle and liver of fish fed SO diet were significantly higher than those in the FO group. The ratio of n-3 poly-unsaturated fatty acids (PUFAs) to identified fatty acids in liver decreased significantly, while n-6 PUFAs increased significantly with increasing dietary soybean oil inclusion. The levels of triacylglycerol, non-esterified fatty acid and tumour necrosis factor α, and the activity of aspartate aminotransferase in serum significantly increased in SO group. The total anti-oxidative capacity and expressions of the anti-oxidation-related genes (superoxide dismutase 1 and 2, catalase, glutathion peroxidase and nuclear factor erythroid 2-related factor 2) were significantly decreased by dietary soybean inclusion. Dietary soybean oil significantly decreased the gene expressions of the anti-inflammatory cytokines (arginase I and interleukin 10), and increased the pro-inflammatory cytokines (tumour necrosis factor α and interleukin

    Full Text Available Cost of conventional protein sources is on the increase recently; hence, there is the need for cheaper alternative sources that will not compromise the performance characteristics of broiler birds taking into consideration the cost of production. Moringa leaf meal has been reported to increase the performance of broiler birds due to its rich protein content. Two hundred day-old broiler chicks were used to assess the effects of partial replacement of soya bean meal with Moringa (Moringa oleifera leaf meal on broiler chickens in an 8-wk feeding trial. The birds were randomly assigned in equal numbers into five dietary treatments: 0, 5, 10, 15, and 20 % Moringa leaf meal (MOLM. Each treatment was replicated four times with 10 birds per replicate. The results showed that final weight, weight gain, daily weight gain, total feed intake, daily feed intake and feed conversion ratio were significantly (p0.05 effect on primal cut parts and relative organ weight. From the results of this study, replacement of soybean meal with MOLM up to 20% did not have any adverse effect on growth performance and carcass traits of broiler chickens.

    The aim of the study was to evaluate the effect of soybean meal enriched with Cu(II), Zn(II), Fe(II) and Cr(III) by biosorption on egg traits (egg weight, eggshell strength, eggshell thickness, yolk colour, albumen height) and performance of laying hens. Also, the effect of increased microelement doses in biological form on egg quality parameters and hens performance was investigated. A consumer questionnaire was undertaken to evaluate the organoleptic parameters of the eggs. Generally, our study showed that in the groups fed with the new biological supplement, egg quality parameters improved, including eggshell strength, eggshell thickness, albumen height and yolk colour. The biological form of microelements also improved the feed conversion rate, especially in the group fed with a biological form of Cr(III). Moreover, the new supplement improved organoleptic parameters of the eggs, in comparison to the inorganic form of microelements as well as to chelate. Enriched soybean meal could constitute an alternative for currently used feed additives with microelements. Copyright © 2013 Elsevier Ltd. All rights reserved.

    This study evaluated egg production and quality variables of caged and free-range Hy-Line Brown laying hens fed soybean meal (SBM) and soybean-meal-free (SBMF) diets. Hens were randomly assigned to the same 2 dietary treatments within 3 location blocks. SBM and SBMF diets with equivalent calculated nutrient content were prepared based on Hy-Line Brown rearing guidelines. The SBMF diets utilized cottonseed meal, corn distillers dried grains with solubles, corn gluten meal, and wheat middlings in place of dehulled soybean meal. The experiment was conducted between August 2015 and January of 2016 within the TAMU Poultry Research Center and data analyzed over 6 consecutive 28-day periods. Data were analyzed as a split-plot with rearing systems designated whole plots and diets designated as subplots. Hens reared in the free-range rearing system peaked a couple of wk later than those hens within the more conventional indoor caged system, and cumulative production data were considerably more variable for hens raised in the free-range environment. Cumulative egg production, feed per dozen eggs and feed conversion ratio (g feed/g egg) were 92 ± 1.23 and 86 ± 1.84%, 1.45 ± 0.02 and 1.89 ± 0.05 kg, and 2.14 ± 0.04 and 2.77 ± 0.08 (P free-range rearing systems.

    The present study examined longitudinal associations between four family meal patterns (i.e. never had regular family meals, started having regular family meals, stopped having regular family meals, maintained having regular family meals) and young adult parents' dietary intake, weight-related behaviours and psychosocial well-being. In addition, family meal patterns of parents were compared with those of non-parents. Analysis of data from the longitudinal Project EAT (Eating and Activity in Adolescents and Young Adults) study. Linear and logistic regressions were used to examine the associations between family meal patterns and parents' dietary intake, weight-related behaviours and psychosocial well-being. School and in-home settings. At baseline (1998; EAT-I), adolescents (n 4746) from socio-economically and racially/ethnically diverse households completed a survey and anthropometric measurements at school. At follow-up (2015; EAT-IV), participants who were parents (n 726) and who were non-parents with significant others (n 618) completed an online survey. Young adult parents who reported having regular family meals as an adolescent and as a parent ('maintainers'), or who started having regular family meals with their own families ('starters'), reported more healthful dietary, weight-related and psychosocial outcomes compared with young adults who never reported having regular family meals ('nevers'; Pfamily meal starters than non-parents. Results suggest that mental and physical health benefits of having regular family meals may be realized as a parent whether the routine of regular family meals is carried forward from adolescence into parenthood, or if the routine is started in parenthood.

    This study was designed to determine the effects on laying performance and egg quality resulting from partial substitution of soybean meal (SBM) with low-fiber alfalfa (LFA; Medicago sativa L.) meal in the diet of early-phase laying hens. ISA Brown layers, 18 wk of age, were randomly allocated to 2 dietary treatments and fed for 10 wk. The hens were fed 2 wheat middling-based diets: a control diet, which contained SBM (15% of diet), and a test diet containing LFA (15% of diet) as the main protein source. Low-fiber alfalfa meal was obtained by a combination of sieving and air-classification processes. Feed intake was recorded daily, and egg production was calculated on a hen-day basis; eggs from each group were weekly collected to evaluate egg components and quality. The partial substitution of SBM with LFA had no adverse effect on growth performance of early-phase laying hens. Egg production and none of the egg-quality traits examined were influenced by dietary treatment, except for yolk color (P alfalfa meal in the laying-hen diet can positively influence yolk quality without adversely affecting productive traits. © 2014 Poultry Science Association Inc.

    Cottonseed meal (CM) was used at up to 36.95% content in the diet (replacing 60% of dietary fish meal protein) without any negative eff ects on growth performance of pre-adult grass carp (initial body weight, 761 g) under outdoor conditions. A culture trial was conducted in net cages installed in a large concrete pond. Seven isonitrogenous and isoenergetic diets containing a gradient of CM concentrations (0, 12.2%, 24.4%, 36.6%, 48.8%, 54.8%, and 61.0%) as replacement for dietary fish meal protein (0, 20%, 40%, 60%, 80%, 90%, and 100%) were formulated. Dietary non-resistant starch (from maize) was inverse to dietary CM. Growth performance and feed utilization of fish fed the diets containing CM replacing 0-40% fishmeal protein were not aff ected after the 6-week feeding trial. Accumulation of hepatopancreatic total gossypol in the hepatopancreas was significantly correlated with free gossypol content in the diets (HTG=88.6+1.5×DFG, R 2=0.89, Preplacement). Increasing dietary CM content increased serum alanine aminotransferase levels but decreased serum alkaline phosphatase, cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, and albumin ( P<0.05).

    Full Text Available The objective of this experiment was to determine the concentration and digestibility of crude protein (CP and amino acid (AA in meat meal (MM, and to compare these values with the respective values in soybean meal (SBM. Six barrows (initial body weight = 66.9±3.8 kg surgically fitted with a T-cannula at the distal ileum were allotted to a replicated 3×3 balanced Latin square design with 3 diets and 3 periods. Two experimental diets containing test ingredients as the sole source of AA were prepared to estimate the apparent ileal digestibility (AID for CP and AA by the direct method. An N-free diet was also prepared to estimate basal endogenous losses of CP and AA. All experimental diets contained 5% chromic oxide as an indigestible index. Each period consisted of a 5-d adaptation period and a 2-d of ileal digesta collection period. Ileal digesta samples were collected from 0900 to 1700 on d 6 and 7 of each period. The concentrations of CP, Lys, Met, and Trp in MM and SBM were analyzed to be 64.1, 3.5, 1.1 and 0.6, and 45.6, 2.8, 0.8, and 0.3%, respectively. The AID of all AA except Gly in MM was less (p<0.05 than in SBM. The AID of Lys, Met, and Trp in MM was estimated to be 56.0, 71.7, and 47.1%, respectively. The SID of all AA in MM was less (p<0.05 than in SBM. The SID of Lys, Met, and Trp was 65.1, 79.2, and 78.5%, respectively. In conclusion, the CP and AA contents in MM were greater than those in SBM whereas the ileal digestibility of all AA in MM was less than in SBM.

    Involvement in meal preparation and eating meals with the family are associated with better dietary patterns in adolescents, however little research has included older children or longitudinal study designs. This 3-year longitudinal study examines cross-sectional and longitudinal associations between family food involvement, family dinner meal frequency and dietary patterns during late childhood. Questionnaires were completed by parents of 188 children from Greater Melbourne, Australia at baseline in 2002 (mean age=11.25years) and at follow-up in 2006 (mean age=14.16years). Principal components analysis (PCA) was used to identify dietary patterns. Factor analysis (FA) was used to determine the principal factors from six indicators of family food involvement. Multiple linear regression models were used to predict the dietary patterns of children and adolescents at baseline and at follow-up, 3years later, from baseline indicators of family food involvement and frequency of family dinner meals. PCA revealed two dietary patterns, labeled a healthful pattern and an energy-dense pattern. FA revealed one factor for family food involvement. Cross-sectionally among boys, family food involvement score (β=0.55, 95% CI: 0.02, 1.07) and eating family dinner meals daily (β=1.11, 95% CI: 0.27, 1.96) during late childhood were positively associated with the healthful pattern. Eating family dinner meals daily was inversely associated with the energy-dense pattern, cross-sectionally among boys (β=-0.56, 95% CI: -1.06, -0.06). No significant cross-sectional associations were found among girls and no significant longitudinal associations were found for either gender. Involvement in family food and eating dinner with the family during late childhood may have a positive influence on dietary patterns of boys. No evidence was found to suggest the effects on dietary patterns persist into adolescence. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Waste materials have a strong potential in the bioremediation of oil-contaminated sites, because of their richness in nutrients and their economical feasibility. We used sewage sludge, soybean meal and wheat straw to biostimulate oil degradation in a heavily contaminated desert soil. While oil degradation was assessed by following the produced CO2 and by using gas chromatography-mass spectrometry (GC-MS, shifts in bacterial community composition were monitored using illumina MiSeq. The addition of sewage sludge and wheat straw to the desert soil stimulated the respiration activities more than the addition of soybean meal. GC-MS analysis revealed that the addition of addition of sewage sludge and wheat straw resulted in 1.7 to 1.8 fold increase in the degraded C14 to C30 alkanes, compared to only 1.3 fold increase in the case of soybean meal addition. The degradation of ≥ 90% of the C14 to C30 alkanes were measured in the soils treated with sewage sludge and wheat straw. MiSeq sequencing revealed that the majority (76.5-86.4% of total sequences of acquired sequences from the original soil belonged to Alphaproteobacteria, Gammaproteobacteria and Firmicutes. Multivariate analysis of operational taxonomic units (OTUs placed the bacterial communities of the soils after the treatments in separate clusters (ANOSIM R=0.66, P=0.0001. The most remarkable shift in bacterial communities was in the wheat straw treatment, where 95-98% of the total sequences belonging to Bacilli. We conclude that sewage sludge and wheat straw are useful biostimulating agents for the cleanup of oil-contaminated desert soils.

    Full Text Available Abstract Background Obesity is a state of chronic low-grade inflammation. Chronic low-grade inflammation is associated with the pathophysiology of both type-2 diabetes and atherosclerosis. Prevention or reduction of chronic low-grade inflammation may be advantageous in relation to obesity related co-morbidity. In this study we investigated the acute effect of dietary protein sources on postprandial low-grade inflammatory markers after a high-fat meal in obese non-diabetic subjects. Methods We conducted a randomized, acute clinical intervention study in a crossover design. We supplemented a fat rich mixed meal with one of four dietary proteins - cod protein, whey isolate, gluten or casein. 11 obese non-diabetic subjects (age: 40-68, BMI: 30.3-42.0 kg/m2 participated and blood samples were drawn in the 4 h postprandial period. Adiponectin was estimated by ELISA methods and cytokines were analyzed by multiplex assay. Results MCP-1 and CCL5/RANTES displayed significant postprandial dynamics. CCL5/RANTES initially increased after all meals, but overall CCL5/RANTES incremental area under the curve (iAUC was significantly lower after the whey meal compared with the cod and casein meals (P = 0.0053. MCP-1 was initially suppressed after all protein meals. However, the iAUC was significantly higher after whey meal compared to the cod and gluten meals (P = 0.04. Conclusion We have demonstrated acute differential effects on postprandial low grade inflammation of four dietary proteins in obese non-diabetic subjects. CCL5/RANTES initially increased after all meals but the smallest overall postprandial increase was observed after the whey meal. MCP-1 was initially suppressed after all 4 protein meals and the whey meal caused the smallest overall postprandial suppression. Trial Registration ClinicalTrials.gov ID: NCT00863564

    This study investigated the effect of different timings of milk intake on body iron stores and improvement in the dietary habit of female collegiate rhythmic gymnasts. Subjects took iron tablets at both breakfast and dinner times during a weight-loss period. In addition, subjects ingested low-fat milk twice a day either at breakfast or dinner (group I; n = 7), or between meals (group II; n = 6) for 3 mo. Blood was collected four times. Red blood cell count, hemoglobin, serum iron, ferritin and erythropoietin concentrations were measured. Subjects completed a dietary survey for three consecutive days before each blood sampling. The mean body fat in both groups I and II was significantly lower after 3 mo than at the start of the study (p meals. In conclusion, iron-supplemented meals via milk ingestion did not decrease body iron stores and maintained higher body iron stores compared to a diet that included milk intake between meals. Further, milk intake with meals is related to keeping regular meal times and frequency.

Live weight gain percent (165% obtained in fish fed soybean meal based diet was not significantly different to that achieved (171% in fish fed Diet I. Specific growth rate percent, SGR (2.79%, feed conversion ratio FCR (1.40 and protein efficiency ratio PER (1.79 recorded in fish fed Diet II were also more less comparable to those fed control diet. Mortality was not recorded in the period of the feeding trial. Body composition of the fish fed soybean meal based diet (Diet II was also comparable to that fed control diet. Significantly higher fat content was noted in fish fed Diet II. However, the protein contents were not changed in fish fed Diet I and II. Similarly, no significant differences (P > 0.05 in protein productive value were noted between the two groups. However, ash content differed significantly (P < 0.05 in fish fed Diet I and II. Although soybean meal-based diet depressed growth and feed conversion efficiencies of the fish to some extent, inclusion of soybean meal was found to be cost-effective alternative to fish meal.

    Two experiments were conducted to determine the effects of phytate, phytase, fiber, and soybean oil on apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of Ca and on ATTD of P in fish meal fed to growing pigs. In Exp. 1, 40 growing pigs (initial average BW: 19.16 ± 2.04 kg) were randomly allotted to 1 of 5 diets with 8 pigs per treatment and placed in metabolism crates. Four diets were used in a 2 ´ 2 factorial design with 2 levels of phytate (0 or 0.7%) and 2 levels of microbial phytase (0 or 500 phytase units/kg). The diet containing no phytate was based on sucrose, cornstarch, fish meal, casein, and soybean oil, and the diet containing 0.7% phytate was based on corn, corn germ, fish meal, casein, and soybean oil. A Ca-free diet was used to determine basal endogenous losses of Ca. Feces were collected from d 6 to 13 after a 5-d adaptation period. Results indicated that the ATTD and STTD of Ca in fish meal and the ATTD of P increased ( phytase was used and were greater ( phytase and fiber increased the ATTD and STTD of Ca and the ATTD of P in fish meal, but inclusion of soybean oil did not affect digestibility of Ca or P. The observation that values for the ATTD and STTD of Ca and ATTD of P are greater in corn-based diets than in cornstarch-based diets indicates that values for the digestibility of Ca and P obtained in cornstarch-based diets may not always be representative for the digestibility in practical corn-based diets.

    Consumers have begun to awaken to the food on their plates with respect to human health and the environment, as well as animal welfare. They have become more demanding about what they buy or prefer in their food, such as soy-free, gluten-free, or organic products. The objective of this study was to evaluate consumer acceptance of eggs from hens fed soybean meal or soybean-free diets utilizing cottonseed meal and distillers' dried grains, using cage or free-range rearing systems. All eggs were stored at the sensory lab at Texas A&M University (TAMU) for a d prior to each test at 4°C. A panel of consumers (n = 60) made up of TAMU students, faculty, and staff, ages 18 to 50, were recruited to evaluate consumer acceptance based on 2 tests using scrambled and hard cooked eggs. Samples were placed in separate weigh boats labeled with 3-digit codes to avoid visual bias. Sensory ballots were based on overall like or dislike of flavor, texture, odor, and color using the 9-point hedonic scales. For scrambled eggs, flavor did not differ (P > 0.05), but texture liking was higher (P = 0.064) for scrambled eggs from the soybean-free diet (7.08) vs. scrambled eggs from the soybean meal diet (6.65). With respect to the hard cooked eggs, the consumer panel preferred the flavor of the eggs from the caged rearing system (7.11) vs. eggs from the free-range system (6.60; P = 0.014). Consumers liked the texture (P = 0.018) for eggs collected from hens fed soybean meal (6.91) vs. eggs from hens fed the soybean-free diet (6.30).

    Away from home (AFH) meals are known to be energy-dense and of poor diet quality. Both direct and indirect exposure (for example, neighborhood restaurant density) to AFH meals have been implicated as contributors to higher body weight and adverse health outcomes. To examine the association of frequency of eating AFH and fast-food meals with biomarkers of chronic disease and dietary intake. This cross-sectional study used frequency of AFH and fast-food meal and biomarker data from the NHANES 2005-2010. Information on weekly frequency of AFH and fast-food meals was collected via questionnaire during the household interview. The metabolic biomarkers examined included body mass index (BMI), serum cholesterol (total, high-density lipoprotein (HDL) and low-density lipoprotein (LDL)), triglycerides, glycohemoglobin and fasting glucose (n=8314, age⩾20, National Health and Nutrition Examination Surveys (NHANES) 2007-2010). Biomarkers of dietary exposure included serum concentrations of vitamins A, D, E, C, B-6, B-12, folate and carotenoids (n=4162; 2005-2006). Multiple linear and logistic regression methods adjusted for complex survey methodology and covariates. American adults reported a mean of 3.9 (95% confidence interval 3.7, 4.0) AFH and 1.8 (1.6, 1.9) fast-food meals/week. Over 50% of adults reported ⩾3 AFH and >35% reported ⩾2 fast-food meals/week. The mean BMI of more frequent AFH or fast-food meal reporters was higher (Ptrend⩽0.0004). Serum concentrations of total, LDL and HDL-cholesterol were related inversely with frequency of AFH meals (Pfast-food meals and serum HDL-cholesterol were also related inversely (P=0.0001). Serum concentrations of all examined micronutrients (except vitamin A and lycopene) declined with increasing frequency of AFH meals (Pfast-food meals had higher BMI and lower concentrations of HDL-cholesterol; however, profiles of other biomarkers did not indicate higher metabolic risk.

    The rise of obesity prevalence has been attributed in part to an increase in food and beverage portion sizes selected and consumed among overweight and obese consumers. Nevertheless, evidence from observations of adults is mixed and contradictory findings might reflect the use of small or unrepresentative samples. The objective of this study was i) to determine the extent to which BMI and dietary restraint predict self-selected portion sizes for a range of commercially available prepared savoury meals and ii) to consider the importance of these variables relative to two previously established predictors of portion selection, expected satiation and expected liking. A representative sample of female consumers (N = 300, range 18-55 years) evaluated 15 frozen savoury prepared meals. For each meal, participants rated their expected satiation and expected liking, and selected their ideal portion using a previously validated computer-based task. Dietary restraint was quantified using the Dutch Eating Behaviour Questionnaire (DEBQ-R). Hierarchical multiple regression was performed on self-selected portions with age, hunger level, and meal familiarity entered as control variables in the first step of the model, expected satiation and expected liking as predictor variables in the second step, and DEBQ-R and BMI as exploratory predictor variables in the third step. The second and third steps significantly explained variance in portion size selection (18% and 4%, respectively). Larger portion selections were significantly associated with lower dietary restraint and with lower expected satiation. There was a positive relationship between BMI and portion size selection (p = 0.06) and between expected liking and portion size selection (p = 0.06). Our discussion considers future research directions, the limited variance explained by our model, and the potential for portion size underreporting by overweight participants.

Twenty hybrid male piglets, averaging 15.4 ± 0.8 kg initial body weights were allotted to four experimental diets (five replicates per treatment based on soybean meal, cotton seed cake, cooked or roasted soybeans over a 98-day period. The rations containing the commonly used soybean meal and cotton seed cake were used as control diets. Results showed that the weight gain and feed conversion ratio obtained with diets containing roasted and cooked soybeans were significantly (P 0.05 compared to the soybean meal diet. Comparison of the two methods of heat treatment showed no significant difference on animal performances. Feed costs to produce one kilogram live weight, calculated as mean costs for both growth phases, although not significant between treatments, showed a slightly lower value in roasted soybean diets. These results show that the roasting method can be used with the same advantages as the cooking method.

    This study evaluated the nutritional value of 14 canola meals from new varieties of canola and compared them to conventional canola meal samples and soybean meals in chickens. Five experiments that included different sources of canola meals or soybean meals were conducted. For each experiment, a precision-fed rooster assay with conventional or cecectomized roosters was conducted to determine TMEn or amino acid digestibility. Analyzed nutritional composition of the canola meal samples indicated increases in crude protein and amino acids for all test canola meals (49.41 to 50.58% crude protein on a dry matter basis) compared to conventional canola meals (40.73 to 43.01%). All test canola meals also contained lower amounts of neutral detergent fiber and acid detergent fiber. Most test canola meals had significantly higher TMEn values than the conventional canola meals (P nutritional value of the canola meal from new varieties of canola was greater than conventional canola meal for poultry. © 2015 Poultry Science Association Inc.

    Artificial neural network models offer an alternative to linear regression analysis for predicting the amino acid content of feeds from their chemical composition. A group method of data handling-type neural network (GMDH-type NN), with an evolutionary method of genetic algorithm, was used to predict methionine (Met) and lysine (Lys) contents of soybean meal (SBM) and fish meal (FM) from their proximate analyses (i.e. crude protein, crude fat, crude fibre, ash and moisture). A data set with 119 data lines for Met and 116 lines for Lys was used to develop GMDH-type NN models with two hidden layers. The data lines were divided into two groups to produce training and validation sets. The data sets were imported into the GEvoM software for training the networks. The predictive capability of the constructed models was evaluated by their abilities to estimate the validation data sets accurately. A quantitative examination of goodness of fit for the predictive models was made using a number of precision, concordance and bias statistics. The statistical performance of the models developed revealed close agreement between observed and predicted Met and Lys contents for SBM and FM. The results of this study clearly illustrate the validity of GMDH-type NN models to estimate accurately the amino acid content of poultry feed ingredients from their chemical composition . (Author)

    To develop a worked example of product reformulation of a very popular 'junk food' to meet nutritional guidelines for public health in a ready meal. Indicative survey of popular Margherita pizzas, followed by product reformulation, applying dietary guidelines to generate a single-item pizza meal containing 30 % daily amounts of energy and all nutrients. An iterative process was used; first to optimize nutrient balance by adjusting the proportions of bread base, tomato-based sauce and mozzarella topping, then adding ingredients to provide specific nutrients and consumer tasting. Urban areas of contrasting socio-economic status. Untrained unselected adults (n 49) and children (n 63), assessing pizza at tasting stations. Most commercial pizzas provide insufficient information to assess all nutrients and traditional Margherita pizza ingredients provide insufficient Fe, Zn, iodine, and vitamins C and B12. Energy content of the portions currently sold as standard range from 837 to 2351 kJ (200 to 562 kcal), and most exceed 30 % Guideline Daily Amounts for saturated fat and Na when a 2510 kJ (600 kcal) notional meal is considered. The 'nutritionally balanced pizza' provides the required energy for a single-item meal (2510 kJ/600 kcal), with all nutrients within recommended ranges: Na (473 mg, ∼45 % below recommended level), saturated fat (<11 % energy) and dietary fibre (13·7 g). Most adults (77 %) and children (81 %) rated it 'as good as' or 'better than' their usual choice. Nutritional guidelines to reduce chronic diseases can be applied to reformulate 'junk food' ready meals, to improve public health through a health-by-stealth approach without requiring change in eating habits.

All the serum biochemistry parameters evaluated differs significantly (P≤0.05 except albumin and cholesterol (P>0.05 among the dietary treatments. The weight of the kidney, heart, pancrease, proventriculus and spleen were influenced by the dietary treatments (P≤0.05. The weights of breast and empty gizzard increased (P≤0.05 linearly with MOLM inclusion while the wings, thigh and drum stick compared (P≤0.05 with those fed the control diet. The villi length and muscle thickness were significantly (P≤0.05 influenced by MOLM inclusion. The MOLM supplemented birds had longer villi than birds in the control group. The result of the this study showed that replacement of soybean meal with MOLM up to 30% inclusion in the diets of Nera black cocks was not detrimental to organ weights, carcass characteristics, sensory attributes and villi morphometrics. However, some serum parameters were adversely affected.

    Natural laccase-mediator systems have been well recognized as an eco-friendly and energy-saving approach in environmental remediation, whose further application is however limited by the high cost of natural mediators and relatively long treatment time span. This study evaluated the water extract of soybean meal, a low-cost compound system, in mediating the laccase catalyzed degradation of a model contaminant of emerging concern, sulfadimethoxine (SDM), and demonstrated it as a promising alternative mediator for soil and water remediation. Removal of 73.3% and 65.6% was achieved in 9 h using soybean meal extract (SBE) as the mediating system for laccase-catalyzed degradation of sulfadimethoxine at the concentration of 1 ppm and 10 ppm, respectively. Further degradation of sulfadimethoxine was observed with multiple SBE additions. Using SBE as mediator increased the 9-h removal of SDM at 1 ppm initial concentration by 52.9%, 49.4%, and 36.3% in comparison to the system mediated by 1-Hydroxybenzotriazole (HBT), p-Coumaric acid (COU) and 2,2'-azinobis(3-ethylbenzthiazoline-6-sulfonate) (ABTS), respectively. With the detection of stable coupling products formed with radical scavenger (5,5-Dimethyl-1-pyrroline N-oxide, DMPO), three phenolic compounds (vanillin, apocynin, and daidzein) in SBE were confirmed to serve as mediators for Trametes versicolor laccase. Reaction pathways were proposed based on the results of High Resolution Mass Spectrometry. SO 2 excursion happened during SDM transformation, leading to elimination of antimicrobial activity. Therefore, as a natural, phenol rich, and affordable compound system, the future application of SBE in wastewater and soil remediation is worth exploring. Copyright © 2017 Elsevier Ltd.

    Full Text Available A study was conducted to evaluate effects of alfalfa meal on growth performance and gastrointestinal tract development of growing layer ducks to provide evidence for application of alfalfa meal in the duck industry. Two hundred and fifty-six healthy Shaoxing 7-wk old growing layer ducks were selected and randomly allocated to 1 of 4 dietary treatments based on corn and soybean meal and containing 0, 3, 6, and 9% of alfalfa meal for 8 wks. Each treatment consisted of 4 replicates of 16 ducks each. Briefly, birds were raised in separate compartments, and each compartment consisted of three parts: indoor floor house, adjacent open area and a connecting water area. The results showed: i Growing ducks fed alfalfa meal diet were not significantly different in average daily gain, feed intake and gain-to-feed ratio from those fed no alfalfa diet (p>0.05. ii Alfalfa meal increased the ratio crop, gizzard to live weight, caecum to live weight, the caecum index of growing ducks (p<0.05. iii Villus height in duodenum and jejunum of growing ducks increased significantly with the increase of alfalfa meal levels (p<0.05. Crypt depth in duodenum and jejunum of growing ducks decreased significantly with the increase of alfalfa meal levels (p<0.05. This experiment showed that feeding of alfalfa meal to growing layer ducks could improve gastrointestinal tract growth and small intestinal morphology without effect on performance. This experiment provides evidence that alfalfa meal is a very valuable feedstuff for growing layer ducks.

Twelve Holstein cows with an average milk yield of 22.0 ± 2.3 kg/day, and with 235 ± 40 days in milk were included in this study. The animals were grouped into three balanced and contemporary 4x4 Latin squares for an experimental period of 21 days. On the 15th day of each period, milk and urine samples were collected for microbial protein synthesis determination. Total excretion of urine (L/day, milk urea nitrogen (MUN and blood urea were higher for the diets with high CP, regardless of the nitrogen source. Nitrogen efficiency was higher for cows fed diets with low CP. Cows in the final third of lactation can be fed diets with reduced CP levels, regardless of the nitrogen source, soybean meal or urea, without influencing the synthesis of microbial protein or the composition of the nitrogen fraction of milk.

    A 120-day feeding experiment was conducted to investigate the effects of partial replacement of brown fish meal (BFM) by fermented soybean meal (FSBM) in diets of Chinese soft-shelled turtle ( Pelodiscus sinensis). The turtles (initial mean body weight, (115.52 ± 1.05) g) were fed with three experimental diets, in which 0%, 4.72% and 9.44% BFM protein was replaced by 0%, 3% and 6% FSBM, respectively. Results showed that the feeding rate (FR), specific growth rate (SGR) and feed efficiency ratio (FER) of turtles fed with the diet containing 3% FSBM were not significantly different from the control group (0% FSBM) ( P > 0.05). However, FR, SGR and FER of turtles fed with the diet containing 6% FSBM were significantly lower than those of the control group ( P 0.05). However, the uric acid concentration in turtles fed with the diet containing 3% or 6% FSBM was significantly lower than that in the control group ( P 0.05). The results suggested that FSBM could replace 4.72% BFM protein in turtle diets without exerting adverse effects on turtle growth, feed utilization and measured immune parameters.

    The aim of this study was to determine the effects of soybean meal (SBM) substitution by a mixture of rapeseed meal (RSM), white lupine seeds (WLS) and pea seeds (PS) on productivity, nutrient digestibility, nitrogen retention and gastrointestinal function in Hyplus rabbits. The Control diet (SBM 15 ) contained 15% SBM, whereas Diet SBM 7.5 contained 7.5% SBM, 5% RSM, 4% WLS and 3% PS. In Diet SBM 0, SBM was completely replaced by RSM, WLS and PS (10%, 8% and 6%, respectively). A production trial was performed on 90 Hyplus rabbits aged from 35 to 84 d (45 each sex; 953 ± 4.6 g). A digestion and balance trial was conducted on 30 rabbits. Additionally, several parameters of the gastrointestinal tracts from eight animals from each group were analysed, where special attention was paid to the enzymatic activity of microbiota and the short-chain fatty acids concentration in caecum and colon. The experimental diets did not cause significant differences regarding performance parameters evaluated in vivo and post-mortem, and in the nutrient and energy digestibility or nitrogen retention. The observed changes in the enzymatic activity of large gut microbiota, including the selective increase in secretion of glycoside hydrolases by bacterial cells, seem to be responsible for the unchanged growth performance of rabbits fed diets where SBM was substituted by a mixture of RSM, WLS and PS. The obtained results indicate that in rabbit diets SBM may be, partially or completely, successfully replaced by a feed mixture of RSM, WLS and PS.

    Objectives were to compare belly, bacon processing, bacon slice, and sensory characteristics from pigs fed high protein canola meal (CM-HP) or conventional canola meal (CM-CV). Soybean meal was replaced with 0 (control), 33, 66, or 100% of both types of canola meal. Left side bellies from 70 carcasses were randomly assigned to conventional or dry cure treatment and matching right side bellies were assigned the opposite treatment. Secondary objectives were to test the existence of bilateral symmetry on fresh belly characteristics and fatty acid profiles of right and left side bellies originating from the same carcass. Bellies from pigs fed CM-HP were slightly lighter and thinner than bellies from pigs fed CM-CV, yet bacon processing, bacon slice, and sensory characteristics were unaffected by dietary treatment and did not differ from the control. Furthermore, testing the existence of bilateral symmetry on fresh belly characteristics revealed that bellies originating from the right side of the carcasses were slightly (P≤0.05) wider, thicker, heavier and firmer than bellies from the left side of the carcass.

    The efficacy of an Escherichia coli 6-phytase supplementation (Quantum) on nutrient digestibility-retention and bone ash in laying hens fed corn-soybean meal (CSM) diets was investigated. White Leghorn hens (Shaver and Bovan strains) were fed CSM diets containing 0.35% (positive control, PC), 0.25% (negative control 1, NC1), or 0.15% (negative control 2, NC2) nonphytate P from 21 to 61 wk of age. Six more diets were manufactured by supplementing the negative control diets with 200, 400, and 600 units per kilogram of exogenous phytase resulting in a total of 9 treatments. Each dietary treatment x strain subclass was replicated twice with 6 hens per replication. Fecal and ileal digesta samples were collected at 42 wk of age to determine apparent nutrient digestibility or retention. Left tibiae were collected at 42 and 61 wk of age to determine bone ash. The coefficients for ileal digestibility and fecal retention for protein were higher (P ash percentage was higher (P < 0.05) in 61-wk-old hens fed 200 or 400 units per kilogram of phytase-supplemented NC2 diets. Significantly higher diet AME and fecal protein retention were demonstrated for Shaver hens in comparison to the Bovan hens. Overall, the Quantum phytase was not efficacious at improving nutrient digestibility-retention in laying hens fed CSM diets deficient in nonphytate P.

    2004-01-01

    In spite of a high prevalence of undernutrition among old nursing home residents, studies have generally reported a mean intake of energy sufficient to cover the mean estimated energy requirement. This discrepancy could be due to skipping of meals and hence periods of insufficient energy intake too intermittent to be identified, when mean results are presented. To examine the significance of skipping of (part of) meals on dietary intake and nutritional status of old (65+y) nursing home residents. Participants were 132 nursing home residents (84 (82-85) y). They were characterised according to activity of daily living-functions (ADL-functions), cognitive performance, intake of energy and protein (4-days dietary record), skipping of meals, energy and protein balance, and nutritional status (body mass index (BMI)). The participants had an energy intake, which was significantly higher than the estimated energy requirement (p eat or only had desert at one or more meals during the 4-day registration period. Participants who were skipping meals had a lower BMI, energy and protein intake (all p <0.001) and a higher prevalence of negative protein balance (p <0.01), than the other residents. More focus should be given to individualized nutritional assessment in order to discover the cause to this problem and target individuals who could be helped by nutritional intervention.

    Full Text Available Background. Appropriate complementary feeding practice is essential for growth and development of children. This study aimed to assess dietary diversity and meal frequency practice of infants and young children in Ethiopia. Methods. Data collected in the Ethiopian Demographic and Health Survey (EDHS from December 2010 to June 2011 were used for this study. Data collected were extracted, arranged, recoded, and analyzed by using SPSS version 17. A total of 2836 children aged 6–23 months were used for final analysis. Both bivariate and multivariate analysis were done to identify predictors of feeding practices. Result. Children with adequate dietary diversity score and meal frequency were 10.8% and 44.7%, respectively. Children born from the richest households showed better dietary diversity score (OR = 0.256. Number of children whose age less than five years was important predictor of dietary diversity (OR = 0.690. Mothers who had exposure to media were more likely to give adequate meal frequency to their children (OR = 0.707. Conclusion. Dietary diversity and meal frequency practices were inadequate in Ethiopia. Wealth quintile, exposure to media, and number of children were affecting feeding practices. Improving economic status, a habit of eating together, and exposure to media are important to improve infant feeding practices in Ethiopia.

    To examine behavioral and environmental factors that may be related to dietary behaviors among U.S. high school students. Data were obtained from the 2010 National Youth Physical Activity and Nutrition Study, a cross-sectional study. The study was school-based. Study subjects were a nationally representative sample of students in grades 9 to 12 (n = 11,458). Variables of interest included meal practices, in-home snack availability, and intakes of healthful foods/beverages (fruits, vegetables, water, and milk) and less healthful foods/beverages (fried potatoes, pizza, and sugar-sweetened beverages). Sex-stratified logistic regression models were used to examine associations of meal practices and snack availability with dietary intake. Odds ratios (ORs) were adjusted for race/ethnicity and grade. Eating breakfast daily, frequent family dinners, and bringing lunch from home were associated with higher odds of consuming at least three healthful foods or beverages. High fast-food intake was associated with lower odds of healthful dietary intake and higher odds of sugar-sweetened beverage intake (female OR = 3.73, male OR = 4.60). Students who mostly/always had fruits and vegetables available at home had increased odds of fruits (female OR = 3.04, male OR = 2.24), vegetables (female OR = 2.12, male OR = 1.65), water (female OR = 1.82, male OR = 1.85), and milk intake (female OR = 1.45, male OR = 1.64). Encouraging daily breakfast consumption, frequent family dinners, and fruit and vegetable availability at home may lead to higher intakes of healthful foods among high school students.

A control diet was used for comparison. Each treatment was replicated six times, with nine birds per replicate. The concentration of trypsin inhibitors (TIs) in the test diets was approximately 10,193.4 TIU/kg. Regardless of enzyme supplementation, feed intake (FI) and body weight gain (BWG) of birds in the control group were superior to those on the test diets. Birds that received the protease-free test diets had reduced FI and BWG, but when supplemented with protease, were similar to the control diet in BWG, FI (except 0-35 days) and feed conversion ratio (FCR). When the test diet was supplemented with elevated levels (extradose) of protease and phytase, the BWG was improved during 0-10 days (p = .05) and 0-24 days (p replace SBM in broiler diets, provided the diets are supplemented with elevated levels of protease and phytase. © 2018 Blackwell Verlag GmbH.

Experimental diets were a control containing 27.4 % alfalfa silage, 22.5% corn silage, and 50.1% concentrate, and four diets with either tallow, raw soybean, extruded soybean, or roasted soybean added to provide 1.93% supplemental fat. Dry matter and NEL intakes were similar among treatments, while cows fed fat diets had significantly (P<0.05 high NEL intakes when compared to control with no fat. Supplemental fat, whether tallow or full fat soybeans increased milk production (1.89-2.45 kg/d; P<0.01 and FCM production (1.05-2.79; P<0.01. Milk fat yield and percentage of cows fed fat-supplemented diets were significantly (P<0.01 and P<0.05 respectively higher than control. Between fat-supplemented diets, roasted soybean caused highest milk fat yield and extruded soybean caused lowest milk fat yield. There was no significant effect of supplemental fat on the milk protein and lactose content and yield. Feed efficiency of fat-supplemented diets was significantly (P<0.01 higher than control. Body weight, body weight change and BCS (body condition score of cows, as well as energy balance and energy efficiency were similar between treatments. In conclusion, while there was no significant effect of fat sources on production response of cows, fat originating from heat-treated soybean help to minimize imported RUP (rumen undegradable protein sources level as fish meal in comparison with tallow and raw soybean oil. In the Current study, there was no statistical significance among nutritional values of oil from extruded soybeans and roasted soybeans.

    The major impact of the livestock sector on the environment may be reduced by feeding agricultural co-products to animals. Since the last decade, co-products from biodiesel production, such as rapeseed meal (RSM), became increasingly available in Europe. Consequently, an increase in RSM content in livestock diets was observed at the expense of soybean meal (SBM) content. Cultivation of SBM is associated with high environmental impacts, especially when emissions related to land use change (LUC) are included. This study aims to assess the environmental impact of replacing SBM with RSM in finishing pig diets. As RSM has a lower nutritional value, we assessed the environmental impact of replacing SBM with RSM using scenarios that differed in handling changes in nutritional level. Scenario 1 (S1) was the basic scenario containing SBM. In scenario 2 (S2), RSM replaced SBM based on CP content, resulting in reduced energy and amino acid content, and hence an increased feed intake to realize the same growth rate. The diet of scenario 3 (S3) was identical to S2; however, we assumed that pigs were not able to increase their feed intake, leading to reduced growth performance. In scenario 4 (S4), the energy and amino acid content were increased to the same level of S1. Pig performances were simulated using a growth model. We analyzed the environmental impact of each scenario using life-cycle assessment, including processes of feed production, manure management, piglet production, enteric fermentation and housing. Results show that, expressed as per kg of BW, replacing SBM with RSM in finishing pig diets marginally decreased global warming potential (GWP) and energy use (EU) but decreased land use (LU) up to 12%. Between scenarios, S3 had the maximum potential to reduce the environmental impact, due to a lower impact per kg of feed and an increased body protein-to-lipid ratio of the pigs, resulting in a better feed conversion ratio. Optimization of the body protein

    Plant-based feed ingredients typically contain remnants of dietary fibres [DF; non-starch polysaccharides (NSP) and lignin] that have various antinutritive effects in carnivorous fish. Exogenous enzymes have been shown to improve the apparent digestibility coefficients (ADC) of plant-based diets...... presumably by assisting in the breakdown of NSP. This study examined the effects on NSP degradation when supplementing β-glucanase, xylanase, protease or a mix of the three enzymes to an extruded, juvenile rainbow trout (Oncorhynchus mykiss) diet containing 344 g kg−1 de-hulled, solvent-extracted soybean...... meal (SBM).

    This study was conducted to investigate the effects of dietary coconut oil as a medium-chain fatty acid (MCFA) source on performance, carcass composition and serum lipids in male broilers. A total of 540, one-day-old, male Arbor Acres broilers were randomly allotted to 1 of 5 treatments with each treatment being applied to 6 replicates of 18 chicks. The basal diet (i.e., R0) was based on corn and soybean meal and was supplemented with 1.5% soybean oil during the starter phase (d 0 to 21) and 3.0% soybean oil during the grower phase (d 22 to 42). Four experimental diets were formulated by replacing 25%, 50%, 75%, or 100% of the soybean oil with coconut oil (i.e., R25, R50, R75, and R100). Soybean oil and coconut oil were used as sources of long-chain fatty acid and MCFA, respectively. The feeding trial showed that dietary coconut oil had no effect on weight gain, feed intake or feed conversion. On d 42, serum levels of total cholesterol, low-density lipoprotein cholesterol, and low-density lipoprotein/high-density lipoprotein cholesterol were linearly decreased as the coconut oil level increased (pcoconut oil level increased (poil in diets with coconut oil is the optimum level to reduce fat deposition and favorably affect lipid profiles without impairing performance in broilers.

Camelina seeds and buckthorn meal were incorporated in the compound feeds for finishing broilers as natural source of vitamins (beta- carotene, vitamins C, B1, B2, E, F, calcium, phosphorus, magnesium, potassium, sodium, and iron. The experiment was conducted on 600 Hybro PN broilers during the age period 7 – 42 days. The broilers were assigned to 3 groups, a control group © and two experimental groups (E1 and E2, each with 200 broilers (3 groups  3 replicates  100 broilers. Three (phase-feeding compound feeds formulations were used. The control diet consisted mainly of corn, full fat soybean, soybean meal and corn gluten. Camelina seeds (10% replaced full fat soybean in the experimental groups, while additionally, in E2 the classical premix with synthetic vitamins and minerals was replaced by buckthorn meal. The partial results show that the use of Camelina seeds reduced significantly (P<0.05 the final live weight, but the liveability percentage was not influenced by the type of dietary compound feed throughout the experimental period. Carcass fat decreased by 61.44% and 30.72% in the experimental groups compared to the control group.

    Children's consumption of restaurant foods is associated with higher energy intake and lower nutritional quality compared to foods prepared at home. The aim of this pilot study was to test whether an in-restaurant intervention promoting healthy children's meals (i.e. two meals that met nutrition recommendations and were thus healthier than typical children's meal offerings across leading restaurants) affected children's meal selection and intake. Families with 4-to-8-year-old children were recruited from one location of Anderson's Frozen Custard, a regional quick-service restaurant chain. Families were randomly assigned to return to the restaurant during an intervention or control period and were blinded to group assignment. All families received free meals. During the intervention period families also received placemats featuring two healthy "Kids' Meals of the Day" upon restaurant entry. After families finished dining, researchers recorded children's orders and collected leftovers for quantifying dietary intake via weighed plate waste. Poisson regression and chi-square tests were used to compare children's orders between study groups, and t-tests were used to test for differences in dietary intake among children ordering a promoted healthy entrée (main dish) versus those who did not. Fifty-eight families participated. Children who were exposed to the study placemats prior to ordering ordered a significantly greater number of healthy food components compared to controls (p = 0.03). Overall, in the intervention group, 21% of children ordered a healthy entrée or side dish, versus 7% of controls. Children who ordered one of the promoted healthy entrées consumed less saturated fat across the total meal compared to those who did not (p = 0.04). Manipulating the prominence of healthy choices in restaurants may shift children's meal selections. Future research should build on these initial promising results, aiming to increase the potency of the intervention

    Effects of different dietary rumen undegradable (RUP) to degradable (RDP) protein ratios on ruminal nutrient degradation, feed intake, blood metabolites and milk production were determined in early lactation cows. Four multiparous (43 ± 5 days in milk) and four primiparous (40 ± 6 days in milk) tie-stall-housed Holstein cows were used in a duplicated 4 × 4 Latin square design with four 21-day periods. Each period had 14-day of adaptation and 7-day of sampling. Diets contained on a dry matter (DM) basis, 23.3% alfalfa hay, 20% corn silage and 56.7% concentrate. Cows were first offered alfalfa hay at 7:00, 15:00 and 23:00 hours, and 30 min after each alfalfa hay delivery were offered a mixture of corn silage and concentrate. Treatments were diets with RUP:RDP ratios of (i) 5.2:11.6 (control), (ii) 6.1:10.6, (iii) 7.1:9.5 and (iv) 8.1:8.5, on a dietary DM% basis. Different RUP:RDP ratios were obtained by partial and total replacement of untreated soybean meal (SBM) with xylose-treated SBM (XSBM). In situ study using three rumen-cannulated non-lactating cows showed that DM and crude protein (CP) of SBM had greater rapidly degradable fractions. The potentially degradable fractions were degraded more slowly in XSBM. Treatment cows produced greater milk, protein, lactose, solids-non-fat and total solids than control cows. Increasing RUP:RDP reduced blood urea linearly. Feed costs dropped at RUP:RDP ratios of 6.1:10.6 and 7.1:9.5, but not at 8.1:8.5, compared with the 5.2:11.6 ratio. Intake of DM and CP, rumen pH, blood glucose, albumin and total protein, faecal and urine pH, changes in body weight and body condition score, and milk lactose and solids-non-fat percentages did not differ among treatments. Results provide evidence that increasing dietary RUP:RDP ratio from 5.2:11.6 to 7.1:9.5 optimizes nitrogen metabolism and milk production and reduces feed costs in early lactation cows. Reduced blood urea suggests reprodutive benefits.

    The mature jackfruit (Artocarpus heterophyllus) is consumed in Sri Lanka either as a main meal or a meal accompaniment. However, there is no scientific data on the nutrient compositions of cooked jackfruit meals. Thus, the objective of the study was to carry out a nutritional assessment of a composite jackfruit breakfast meal comprising seeds and flesh. A jackfruit meal comprising of flesh (80% available carbohydrate) and seeds (20% available carbohydrate) was included in the study. The study was carried out in a random cross over design. Setting University of Sri Jayewardenepura. Study participants Healthy individuals (n=10, age: 20-30 yrs). The macronutrient contents, rapidly and slowly available glucose (SAG) contents, water solubility index of the jackfruit meal were determined according to standard methods. The GI of the meal was calculated according to FAO/WHO guidelines. The moisture content of the boiled jackfruit flesh was high (82% FW). Jack seeds contained 4.7% protein (FW), 11.1% total dietary fibre (FW) and 8% resistant starch (FW). Jackfruit meal elicited a GI of 75. The Glycaemic Load (GL) of the normal serving size of the meal is medium. The slowly available glucose (SAG) percentage of jackfruit meal (30%) was twice that of the standard. The boiled jackfruit flesh contained disintegrated starch granules while seeds contained intact swollen and disintegrated granules. The jackfruit seeds are a good source of starch (22%) and dietary fibre. The meal is categorized as a low GI meal. The low GI could be dueto the collective contributions from dietary fibre, slowly available glucose and un-gelatinised (intact) starch granules in the seeds.

    Genetic improvement of soybean protein meal is a complex process because of negative correlation with oil, yield, and temperature. This review describes the progress in mapping and genomics, identifies knowledge gaps, and highlights the need of integrated approaches. Meal protein derived from soybean [Glycine max (L) Merr.] seed is the primary source of protein in poultry and livestock feed. Protein is a key factor that determines the nutritional and economical value of soybean. Genetic improvement of soybean seed protein content is highly desirable, and major quantitative trait loci (QTL) for soybean protein have been detected and repeatedly mapped on chromosomes (Chr.) 20 (LG-I), and 15 (LG-E). However, practical breeding progress is challenging because of seed protein content's negative genetic correlation with seed yield, other seed components such as oil and sucrose, and interaction with environmental effects such as temperature during seed development. In this review, we discuss rate-limiting factors related to soybean protein content and nutritional quality, and potential control factors regulating seed storage protein. In addition, we describe advances in next-generation sequencing technologies for precise detection of natural variants and their integration with conventional and high-throughput genotyping technologies. A syntenic analysis of QTL on Chr. 15 and 20 was performed. Finally, we discuss comprehensive approaches for integrating protein and amino acid QTL, genome-wide association studies, whole-genome resequencing, and transcriptome data to accelerate identification of genomic hot spots for allele introgression and soybean meal protein improvement.

    The efficacy of using screwpress extraction for oil was studied with three Controlled Ecological Life-Support System (CELSS) candidate oilseed crops (soybean, peanut, and canola), since use of volatile organic solvents for oil extraction likely would be impractical in a closed system. Low oil yields from initial work indicated that a modification of the process is necessary to increase extraction efficiency. The extracted oil from each crop was tested for stability and sensory characteristics. When stored at 23 degC, canola oil and meal were least stable to oxidative rancidity, whereas peanut oil and meal were least stable to hydrolytic rancidity. When stored at 65 degC, soybean oil and canola meal were least stable to oxidative rancidity, whereas peanut oil and meal were least stable to hydrolytic rancidity. Sensory evaluation of the extracted oils used in bread and salad dressing indicated that flavor, odor intensity, acceptability, and overall preference may be of concern for screwpress-extracted canola oil when it is used in an unrefined form. Overall results with screwpress-extracted crude oils indicated that soybean oil may be more stable and acceptable than canola or peanut under typical storage conditions.

    Evidence has shown that soybean meal is perceived as more palatable than canola meal by dairy calves in short-term preference tests. This study evaluated the effect of protein source on longer-term dietary selection of dairy calves. In experiment 1, 40 Holstein bull calves (11.4 ± 4.3 d of age) were randomly assigned to 1 of 2 choice diets for 6 wk: base starter pellet (S; 12% crude protein; CP) and high-protein pellet (40% CP) containing either (1) soybean meal (SB) or (2) canola meal (CM). In wk 7 to 8, all calves were offered a single pelleted diet containing the protein source to which they were previously exposed. In experiment 2, 22 Holstein bull calves (9.9 ± 4.6d of age) were offered, for 6 wk, a choice of 2 mixed pelleted diets: (1) 70% S and 30% SB (SB mix), or (2) 70% S and 30% CM (CM mix). In wk 7 to 8, calves were randomly assigned to 1 of 2 choice diets, as in experiment 1: (1) SB + S, or (2) CM + S. All feeds were provided ad libitum. Calves received 6 L/d of milk replacer [0.75 kg/d of dry matter (DM)] for the duration of both experiments. Feed intake was recorded daily and calves were weighed every 14 d. Feeds were sampled weekly to analyze DM and nutrient intake. Mixed diets in experiment 2 were analyzed for CP in wk 4 and 6 to assess feed sorting (calculated as actual CP intake as a percentage of predicted intake). In experiment 1, calves offered SB + S in wk 1 to 6 consumed more high-protein pellet than calves offered CM + S [73 vs. 42% of DM intake (DMI)] and, consequently, more CP (168 vs. 117 g/d). Solid feed DMI and average daily gain were similar between treatments. When offered a single diet in wk 7 to 8, calves offered starter containing soybean meal increased intake to a greater extent than calves offered the starter containing canola meal. In experiment 2, calves preferred the SB mix to CM mix (preference ratio: 0.7). Calves consumed more CP than predicted from SB mix in wk 4 and 6 (108 ± 2.0%), indicating that they were sorting in

    The objective of this study was to investigate the responses of meat ducks of 15 to 35 d of age to free gossypol (FG) from cottonseed meal (CSM) and to establish the maximum limits of dietary FG concentration based on growth performance, blood parameters, and tissue residues of gossypol. Nine hundred 15-d-old ducks were randomly allocated to 5 treatments with 10 cages/treatment and 18 ducks/cage on the basis of BW. Five isonitrogenous and isocaloric experimental diets were formulated on a digestible amino acid basis to produce diets in which 0% (without FG), 25% (36 mg FG/kg), 50% (75 mg FG/kg), 75% (111 mg FG/kg), and 100% (153 mg FG/kg) of protein from soybean meal were replaced by that from CSM. Increasing dietary FG content, BW, and ADG decreased (linearly, PDucks fed 36 mg FG/kg (5.83% CSM of diet) diet had a normal histological structure of liver, and muscle (breast and leg) had no residue of gossypol. The maximum limit of dietary FG concentration was estimated to range from a low of 36 mg/kg to maximize serum globulin concentration to a high of 124 mg/kg to minimize feed intake for 22 to 28 d on the basis of a quadratic broken-line model. © The Author 2015.

MTT and comet assay were performed to evaluate SMP’s ability to prevent cell death and DNA damage induced by radiation. The results show that, X-ray radiation (30 KV, 10 mA, 8 min (4 Gy can significantly increase cell death and DNA fragmentation of mouse spleen lymphocytes. Pretreatment with SMP for 2 h before radiation could increase cell viability, moreover, the SMP can reduce X-ray radiation-induced DNA damage. The percentage of tail DNA and the tail moment of the SMP groups were significantly lower than those of the radiation alone group (p < 0.05. These results suggest SMP may be a good candidate as a radioprotective agent.

    Maintaining independence and continuing to live at home is one solution to manage the rising health care costs of aging populations in the United States; furthermore, seniors are at risk of malnutrition and food insecurity. Home-delivered meal programs are a tool to address food, nutrition, and well-being concerns of this population. Few studies have identified outcomes from these programs; this pilot study reviews the nutritional status, dietary intake, well-being, loneliness, and food security levels of seniors participating in a Meals on Wheels delivery service. Clients, new to the meal program, participated in pre- and postphone interviews, and 51 seniors completed the study. The survey was composed of five scales or questionnaires, and statistical analyses were conducted using SPSS. Improvements across all five measures were statistically significant after participating two months in the home-delivered meal program. Implications for further research, practice, and the Older Americans Act are discussed.

    Low linolenic acid soybean oil (LLSO) has been developed as a substitute for hydrogenated soybean oil to reduce intake of trans FA while improving stability and functionality in processed foods. We assessed the dietary impact of substitution of LLSO for hydrogenated soybean oil (HSBO) used in several food categories. All substitutions were done using an assumption of 100% market penetration. The impact of this substitution on the intake of five FA and trans FA was assessed. Substitution of LLSO for current versions of HSBO resulted in a 45% decrease in intake of trans FA. Impacts on other FA intakes were within the realm of typical dietary intakes. No decrease in intake of alpha-linolenic acid was associated with the use of LLSO in place of HSBO because LLSO substitutes for HSBO that are already low in alpha-linolenic acid.

    female quails at 29 weeks of age with an average weight of 186.1 ± 4.0 g distributed in a complete randomized experimental design, with 8 replicates, each one with 10 quails per experimental unit. Diets were isocaloric and isonutritives for crude protein, digestible lysine, digestible methionine + cystine, calcium, available phosphorus and sodium. Thus, it was evaluated a control diet based on corn and soybean meal, and three other diets with partial substitution of the soybean meal for roasted whole soybean, extruded or micronized, so the whole soybean supplied 50% of the crude protein provided by soybean meal in control diet. No differences were observed on egg production, egg mass, feed conversion, viability of the birds, percentage of commercial eggs, egg specific weight, percentage of yolk and albumen neither on egg shell percentage. Substitution of soybean meal for roasted whole soybean reduced feed intake. It was not observed any differences in the studied parameters when soybean meal was replaced by extruded whole soybean. Substitution of soybean meal for micronized whole soybean reduced body weight variation of the quails, resulting in weight loss of the birds. Soybean meal can be substituted, in 50% of the protein, by roasted or extruded whole soybean in diets for laying Japanese quails. However, substitution of the soybean meal for micronized whole soybean, in 50% of the protein, is not recommended, because it worsens the performance results, mainly causing weight loss of the birds.

    This study evaluated the interaction of RUP and fat levels on growth, rumen fermentation, and blood metabolites of Holstein calves. Forty 3-d-old calves (20 females and 20 males) with a starting BW of 40.6 ± 2.8 kg were used in a completely randomized design with a 2 × 2 factorial arrangement of treatments. Within sex treatments were: (1) high RUP and low fat (HRUP-LF); (2) low RUP and high fat (LRUP-HF); (3) high RUP and low fat (HRUP-LF); and high RUP and high fat (HRUP-HF). Low-RUP starter contained 21.5%, whereas high RUP starter contained 34.3% RUP as % of CP, whereas low fat starter contained 2.9% and high starter contained 5.8% crude fat based on DM. Isonitrogenous levels in the starter grain were maintained by replacing solvent soybean meal with heat treated soybean meal while fat levels were increased by the addition of prilled fatty acids. Calves were housed individually and had ad libitum access to water and calf starter throughout the study. All calves were weaned on d 60 of age but remained in the study until d 70 for final measurements. Overall, there was no interaction between RUP and fat levels for measured variables. Starter intake tended ( = 0.09) to be greater for calves fed low fat starter during the postweaning period, although over the whole experiment and during the preweaning period, differences in starter intake were not different. Although there were no differences for most VFA concentrations, the molar proportion of butyrate tended ( RUP ( RUP starter. However, feeding a calf starter with over 3% fat appeared to decrease starter intake as growth progressed.

    Full Text Available Discarded banana is a valuable feed ingredient for poultry feed formulations. However, due to the presence of resistant starches, inclusion of more than 10% banana meal in poultry rations reduces the growth performance. The objective of this study was to determine whether higher levels of banana meal could be included in broiler diets if raw banana is cooked before being processed into meal. Discarded banana (Cavendish collected at harvesting was processed into two types of banana meals. Cooked banana meal was prepared by cooking banana at 100oC for 15 minutes and subsequent drying. Uncooked banana meal was prepared by drying at 800C for three days. Giving a 2 x 4 factorial arrangement, 144 broiler chicks in 48 cages received one of the eight experimental diets containing either cooked or uncooked banana meal at 0, 10, 20 or 30% ad libitum from day 21-42. Birds fed cooked banana meal were significantly heavier on day 28 and 35. Live weight on day 42, weight gain, feed intake or feed conversion efficiency were not affected either by the type or level of banana meal and their interaction. Cooked banana meal increased the weights of the crop and liver significantly. Weight of the small intestine, proventriculus, gizzard abdominal fat pad and the fat free tibia ash contents were not affected by the dietary treatments. It was concluded that uncooked banana meal produced using peeled raw banana can be included up to 30% in nutritionally balanced broiler finisher diets without any adverse effects on performance.

    Meal pattern analysis can be complex because of the large variability in meal consumption. The use of aggregated, generic meal data may address some of these issues. The objective was to develop a meal coding system and use it to explore meal patterns. Dietary data were used from the National Adult Nutrition Survey (2008-2010), which collected 4-d food diary information from 1500 healthy adults. Self-recorded meal types were listed for each food item. Common food group combinations were identified to generate a number of generic meals for each meal type: breakfast, light meals, main meals, snacks, and beverages. Mean nutritional compositions of the generic meals were determined and substituted into the data set to produce a generic meal data set. Statistical comparisons were performed against the original National Adult Nutrition Survey data. Principal component analysis was carried out by using these generic meals to identify meal patterns. A total of 21,948 individual meals were reduced to 63 generic meals. Good agreement was seen for nutritional comparisons (original compared with generic data sets mean ± SD), such as fat (75.7 ± 29.4 and 71.7 ± 12.9 g, respectively, P = 0.243) and protein (83.3 ± 26.9 and 80.1 ± 13.4 g, respectively, P = 0.525). Similarly, Bland-Altman plots demonstrated good agreement (<5% outside limits of agreement) for many nutrients, including protein, saturated fat, and polyunsaturated fat. Twelve meal types were identified from the principal component analysis ranging in meal-type inclusion/exclusion, varying in energy-dense meals, and differing in the constituents of the meals. A novel meal coding system was developed; dietary intake data were recoded by using generic meal consumption data. Analysis revealed that the generic meal coding system may be appropriate when examining nutrient intakes in the population. Furthermore, such a coding system was shown to be suitable for use in determining meal-based dietary patterns. © 2015

    Full Text Available Twelve Holstein cows were given diets containing soybean supplied in different ways in order to identify possible changes in lactation performance and evaluate the economic feasibility of the diets. The diets included: soybean meal only (SM-control; raw soybean (RaS; roasted soybean (RoS and soybean meal plus 5% urea (SMU. The forage consisted of corn silage. We analyzed the dry matter intake, milk production and collected milk samples. To estimate digestibility, we collected six samples of feces over a period of six consecutive days. The intake of dry matter (DM, organic matter (OM, neutral detergent fiber (NDF and non-fiber carbohydrates (NFC did not differ among treatments. On the other hand, crude protein (CP intake was influenced by the diets, and the highest mean values of ether extract (EE were found with the RaS and RoS diets. The intake of total digestible nutrients (TDN was lower in the RaS and RoS diets compared to the control diet. DM, OM, CP, EE, and NDF digestibility were not affected by the different diets, while NFCs were reduced in the RoS diet and TDN decreased with both the RaS and RoS diets. There were also no differences observed across diets for total milk production, production corrected to 3.5% fat, diet efficiency, or milk per kilogram of dry matter and/or crude protein. We conclude that raw and roasted soybeans as well as concentrate plus 5% urea in dry matter may be used instead of soybean meal as feed for high-producing cows, without affecting milk production and composition. We also observed that the SMU diet was the least costly.

    Child feeding practices are multidimensional, and they change rapidly within short age intervals. Suboptimal complementary feeding practices contribute to a rapid increase in the prevalence of undernutrition in children in the age of 6-23 months. Information on child feeding practices among urban resident is limited in Ethiopia. The aim was to measure minimum meal frequency and dietary diversity and associated factors among children 6-23 months of age in Wolaita Sodo, Ethiopia. A community-based cross-sectional study was carried out to select 623 mothers/caregivers with 6-23 months of children reside in Wolaita Sodo town using systematic sampling from March 02 to 20, 2015. An interviewer-administered questionnaire was used to gather information on socio-demographic, child feeding practices and health-related characteristics. Data were entered to Epi-Data version 3.02 and transported to SPSS version 21 for further analysis. Binary logistic regression was used to see the association between the outcome variables and explanatory variables, and multivariable logistic regression was performed to identify independent predictors of minimum dietary diversity and meal frequency. The study revealed that the percentage of 6-23 months of children who meet the recommended level of minimum dietary diversity and meal frequency were 27.3 and 68.9%, respectively. Mothers/caregivers who were housewives and government employees feed their children more diversified foods as compared to mothers who were private workers. As compared to children 17-23 months of age, children in the age group of 6-8 and 9-11 months had better probability to meet minimum dietary diversity. Government-employed and illiterate mothers were less likely to feed their children to fulfil the minimum requirement of meal frequency. Children in the age of 9-11 months were also less likely to be fed frequently. Even though the study showed better progress as compared to the national prevalence of complementary

    Full Text Available ABSTRACT: The aim of this study was to evaluate the effect of total replacement of raw whole soybean (RAW for roastedwhole soybean (ROS on the production performance of Holstein cows. Two experiments were carried out usinga simple reversal design where RAW has been completely replaced by ROS. In experiment 1, 22 cows (175±60 days in milkwere used, and the dietary inclusion level of RAW or ROS was 3.7% of dry matter (DM. In experiment 2, 16 cows (130±50 days in milkwere used, and thedietary inclusion level of RAW or ROS was 11% of DM. In both experiments, ROS increased milk production by 1.1kgday-1 without changing fat and protein production. Dry matter intake or milk urea nitrogenwere not affected by dietary soy source. In experiment 2, plasma glucose concentration was decreased, and allantoin/creatinine ratio in urine tended to decreasein ROS. Experiment 2 also evaluated the nutrient digestibility and ruminal degradation kinetics of crude protein in two soybean sources. Roasting had no effect on the digestibility of DM, organic matter, and neutral detergent fiber. Roasted whole soybean hadgreater fraction B and lower protein degradation rate than did RAW; this showed that heat treatment was effective in increasing therumen undegradable amino acid flowto the animal, which suggesteda potential mechanism of action for improved performance observed in ROS.

    Full Text Available The objective of our study was to assess the effect of replacing soybean meal with the meal from whole white lupin seeds (Lupinus albus of the Zulika variety in diets on selected haematological indicators in 40-day-old fattened hybrid mallard ducks. A total of 180 Cherry Valley ducks were divided into three groups (E1, E2, and control. The control group was fed a diet containing soybean meal. Soybean meal replaced with 50% and 100% meal of white lupin seeds were used in group E1 and group E2, respectively. At the end of the fattening, 12 ducks (6 males and 6 females were randomly selected from each group for a haematological examination. From the result of this study, it is clear that the effect of the diet was found only on the slightly varying number of white blood cells and on the proportion of monocytes. Ducks of group E2 showed a slight increase in the total number of leukocytes which was accompanied by a decrease in the percentage share of monocytes (P < 0.05. Based on the results, it can be claimed that the replacement of soybean meal with meal from the Zulika variety of whole white lupin seeds in the diet did not have a negative effect on the determined blood indicators. Therefore, whole white lupin seeds were successfully used as the important protein component of the diet for fattening hybrid mallard ducks.

    Full Text Available The objective was to evaluate intake and digestibility of nutrients, as well as milk production and composition of the milk from F1 Holstein × Gyr cows kept on pasture, supplemented with sugarcane and concentrate (28% CP. Five cows with 150±14 lactation days and average milk production of 7.1±2.1 kg/day were distributed in a 5 × 5 Latin square design. The treatments were: soybean meal-based concentrate; soy bean-based concentrate; ground soybean-based concentrate; roasted soybean-based concentrate; and ground, roasted soybean-based concentrate. Dry matter (DM, organic matter, crude protein (CP, neutral detergent fiber (NDF, total carbohydrates and total digestible nutrients intakes were not affected by the diet, but ether extract intake was higher for the animals fed soy bean-based diets than those fed soybean meal. The digestibility of DM, NDF and CP did not differ. The corrected milk yield differed between treatments; animals on the treatment with soy bean-based concentrate had the lowest production in relation to the others, which did not differ from each other. There was no difference between treatments for milk composition. Thus, soybean meal can be replaced by ground soy beans or roasted soy beans (ground or whole in diets for low-yield cows reared on Brachiaria decumbens pastures with no harm to milkproduction or composition. Therefore, the use of these alternative raw materials is recommended whenever their inclusion represents lower feeding costs.

    Effective strategies to increase dietary intake in older persons with a poor appetite are needed. Previous studies have shown that increasing diet variety may increase dietary intake. This has not been tested in older adults with a poor appetite. We investigated if an increased variety of foods within a cooked meal results in a higher meal energy intake in older women with a poor appetite. This study was a randomized, controlled, cross-over trial among 19 older (>65 years) women with a poor appetite. Two cooked meals of similar weight and energy density (except starch) were served under standardized conditions on two weekdays: a test meal consisting of three different varieties of vegetables, meat or fish, and starch components, and a control meal without variety. Participants ate ad libitum and the actual consumed amounts and their nutritional content were calculated. Data were analyzed by mixed linear models. Average intake in energy was 427 kcal (SD 119) for the test meal with variety and 341 kcal (SD 115) for the control meal without variety. This resulted in a statistically significant (for period effects adjusted) mean difference of 79 kcal (95% CI = 25-134). Total meal intake in grams was also higher for the test meal with variety (48 g, 95% CI = 1-97) but protein intake (g) was not (3.7 g, 95% CI = -1.4 to 8.8). This was consistent for all meal components except starch and within each component three varieties were consumed equally. The results of the present study suggest that increasing meal variety may be an effective strategy to increase energy intake in older adults with a poor appetite. Copyright © 2015 Elsevier Ltd.

    Full Text Available This study investigated the effects of a multienzyme complex containing protease and carbohydrase enzymes on the performance and nutrient digestibility of broiler chickens under different rearing conditions from 1 to 42 d of age. Two experimental starter and finisher wheat-soybean meal based diets were used in a two-phase feeding programme, as follows: control diet (C; control diet plus 0.05% multienzyme complex of protease and carbohydrase enzymes (Allzyme Vegpro (VP. At location 1, broilers were raised in battery cages located in an experimental pen, without contact with litter. At location 2, broilers were raised in floor pens built in a commercial farm, and had contact with litter. At location 3, broilers were raised in commercial farms. In general, no differences in growth performance, feed intake or feed conversion ratio were observed in broiler chickens fed on the different diets at location 1. Only, the average daily feed intake from 22 to 42 d was significantly higher in the VP group compared with the C treatment (P<0.01. In addition, the final body weight of the VP group was numerically greater than that of the birds fed with the control diet, although the inclusion of the multienzyme complex did not cause significant effects. However, the ileal digestibilities of dry matter and crude protein were enhanced (P<0.05 by VP in the case of broilers in floor pens (+2.5% and +2.7% for DM and CP, respectively and in the commercial farm (+4.4% and +6% for the DM and CP, respectively at 42 d of age, as well as faecal digestibity of the VP diet in experimental pen. It seemed that the effectiveness of the multienzyme complex on digestibility was higher when conditions of hygiene were poorer and stress was frequent. Based on the results of this study it can be concluded that the multienzyme complex of protease and carbohydrase enzymes might be effective for improving nutrient digestibility in broilers fed with a wheat-soybean meal based diet under

Polyethylene glycol 4000 supplementation had no effect (P > 0.05) on nutrient intake of goats. However, a diet × PEG (P goat were optimized at PEG 4000 supplementation levels of 19.62, 19.62, 19.61 and 19.53 g/goat/day, respectively, for diets containing 20% A. karroo leaf meal. Polyethylene glycol 4000 supplementation had no effect (P > 0.05) on the apparent digestibility of all nutrients. The dietary inclusion level of A. karroo leaf meal at 20% improved (P goats. Crude protein digestibility was optimized at a PEG 4000 supplementation level of 15.78 g/goat/day. Dietary mixture level and PEG 4000 supplementation had no effect (P > 0.05) on final weights of Pedi goats. Similar results were observed for blood urea and glucose concentrations of yearling male Pedi goats. However, daily body weight gain was higher (P goats fed 50% A. karroo leaf meal than those on 20% inclusion level. Polyethylene glycol 4000 has potential to improve the feeding value of tanninifeorus A. karroo leaf meal.

    The objective of this study was to investigate the effects of extruded full-fat soybean (ESB) as a replacement for soybean meal (SBM) on nutrient intake, rumen fermentation, and growth performance of dairy calves. A total of 45 male Holstein dairy calves (42.0±0.5 kg of BW) were randomly assigned to one of three experimental diets: (1) 0% ESB (Control): 35.3% SBM no ESB; (2) 25% ESB: 27.0% SBM+9.0% ESB; and (3) 50% ESB: 19.0% SBM+19.0% ESB. All calves were weaned on day 56 of age and remained in the study until day 70 of age. During the pre-weaning and overall periods, substituting of SBM with ESB had no effect on intake of starter feed, metabolizable energy (ME), CP and non-fiber carbohydrate (NFC). Compared with the control, 50% ESB resulted in a decrease in starter feed intake, and intakes of other nutrients including CP, NFC and ME during the post-weaning period. Substituting SBM with ESB decreased intake of C16 : 0 and increased intakes of n-9 C18 : 1, n-6 C18 : 2 and n-3 C18 : 3 during the pre-weaning, post-weaning and overall periods. Using ESB as a replacement for SBM did not affect average daily gain, feed efficiency, rectal temperature and fecal score over the trial periods. Compared with control, the rumen concentration of NH3-N decreased for 50% ESB on days 35 and 56 of age but not when compared with 25% ESB. Rumen pH, total volatile fatty acids concentrations, and the molar proportions of ruminal acetate, propionate and butyrate were not different among treatments. Body measurements were not affected by the treatments. In conclusion, substitution of SBM with ESB may improve nitrogen utilization efficiency in dairy calves but slightly reduce post-weaning starter intake with no negative outcomes on growth performance and rumen fermentation.

    Peas are locally grown legumes being rich in protein and starch. However, the broad usage of peas as a feed component in poultry nutrition is limited to anti-nutritional factors, which might impair gut morphology and function. This study investigated the effect of feeding raw or differently processed peas compared with feeding a soybean meal-based control diet (C) on intestinal morphology and nutrient transport in broilers. A total of 360 day-old broiler chicks were fed with one of the following diets: The C diet, and 3 diets containing raw peas (RP), fermented peas (FP) and enzymatically pre-digested peas (EP), each supplying 30% of dietary crude protein. After 35 d, jejunal samples of broilers were taken for analyzing histomorphological parameters, active glucose transport in Ussing chambers and the expression of genes related to glucose absorption, intestinal permeability and cell maturation. Villus length (P = 0.017) and crypt depth (P = 0.009) of EP-fed broilers were shorter compared to birds received C. The villus surface area was larger in broilers fed C compared to those fed with the pea-containing feed (P = 0.005). Glucose transport was higher for broilers fed C in comparison to birds fed with the EP diet (P = 0.044). The sodium-dependent glucose co-transporter 1 (SGLT-1) expression was down-regulated in RP (P = 0.028) and FP (P = 0.015) fed broilers. Correlation analyses show that jejunal villus length negatively correlates with the previously published number of jejunal intraepithelial T cells (P = 0.014) and that jejunal glucose transport was negatively correlated with the occurrence of jejunal intraepithelial leukocytes (P = 0.041). To conclude, the feeding of raw and processed pea containing diets compared to a soybean based diet reduced the jejunal mucosal surface area of broilers, which on average was accompanied by lower glucose transport capacities. These morphological and functional alterations were associated with observed mucosal immune

    One hundred dry pregnant cows (1389 lb) and twenty-four pregnant heifers (1034 lb) were assigned by calving date and body condition to one of four dietary treatments for a wintering period during their late gestation. Dietary treatments consisted of supplementing crude protein (CP) at 100 % or 120 % of the recommended intake using either soybean meal or alfalfa leaf meal (ALM) as the supplemental protein source. Cows were group fed (two replicate pens/treatment) while heifers were individually fed for the duration of the study. The study lasted 70 (early) or 85 (late) days for cows and ended when the first cow in each replicate calved. For heifers, the study lasted for 100 days and ended accordingly when each heifer calved. Heifers fed ALM had consumed less (P < .05) hay and corn dry matter (DM). Overall diet DM intakes were unaffected (P > .05) by protein source. Feeding 120 % of recommended protein (2.38 vs 2.07 lb/day) to heifers increased (P < .05) their rate of gain by almost .5 lb/head/day. Cows fed ALM had faster (P < .05) rates of gain when gain was measured 22 days before calving. Once cows calved, weight change was similar (P > .05) for each protein source. However, cows fed alfalfa leaf meal consumed more (P = .054) total dry matter (DM). Calving traits were not affected by protein source or intake. Wintering heifers or cows on ALM-based supplements had no detrimental effect on performance of heifers or cows or their calves at birth. Additional protein may be required by heifers to ensure that they continue gaining weight during late gestation.

Marandu with 1.6 ha each incompletely randomized design with four animals and five supplements to assess the following supplements: 0CS, 25CS and 50CS corresponding to the level of 0,25 and 50% high energy cottonseed meal to replace the meal soybean, provided the amount of 2 kg/animal/day, which were compared to mineral mixture (MM. The supplement 25CS provided higher (P<0.0001 ADG (0.75kg/animal/day-1 compared to supplement 50CS (0.60kg/animal/day-1. The ADG of animals supplemented with 0CS (0.53kg/animal/day-1 did not differ (P<0.0001 of the ADG of the bulls receiving supplementation with 25CS (0.75k /animal/day-1 and 50CS (0,60kg / animal / day-1. The 25CS supplement showed a higher economic return on invested capital in the period. The use of cottonseed meal high energy level of 25% replacement of soybean meal in multiple supplements provided greater weight gain of cattle and improved economic viability.

    One hundred twenty pigs were used to determine effects of graded levels of microbial phytase on the apparent total tract digestibility (ATTD) of P and Ca and the standardized total tract digestibility (STTD) of P in 4 sources of canola meal and in 1 source of soybean meal (SBM) fed to growing pigs. The 4 sources of canola meal were produced from 1 source of high-protein canola seeds and 2 sources of conventional canola seeds with 1 of the conventional canola seeds being divided into 2 separate batches before crushing. Pigs (16.2 ± 5.3 kg initial BW) were individually housed in metabolism crates and were randomly allotted to 1 of 20 diets in a 5 × 4 factorial arrangement of treatments with 5 ingredients and 4 levels of phytase. There were 6 replicate pigs per diet. Five basal diets based on high-protein canola meal (CM-HP), high-temperature processed canola meal (CM-HT), low-temperature processed canola meal (CM-LT), conventional canola meal (CM-CV), or SBM were formulated. The basal diets contained no phytase. Fifteen additional diets were prepared by adding approximately 500, 1,500, or 2,500 phytase units/kg to each of the 5 basal diets. Feces were quantitatively collected for 5 d based on the marker-to-marker approach after a 7-d adaptation period. Results indicated that supplementation of microbial phytase increased (linear, phytase also increased (linear and quadratic, phytase was added, but no differences were observed in the ATTD and STTD of P in SBM, CM-HP, CM-HT, or CM-CV if the highest amount of phytase were added (interaction, phytase on the STTD of P in CM-HP, CM-HT, CM-LT, CM-CV, and SBM. In conclusion, inclusion of graded levels of microbial phytase increased the ATTD and STTD of P in CM-HP, CM-HT, CM-LT, CM-CV, and SBM and the response to microbial phytase added to each ingredient can be predicted by regression equations.

    US hospitals routinely provide food to hospitalized children. The nutritional content of provided foods has not been evaluated. We performed our study to examine meal orders of hospitalized youth and determine whether the nutritional contents of ordered meals meet dietary guidelines. We performed a cross-sectional evaluation among hospitalized youth ≥1 y receiving all nutritional intake by mouth and not on a clear liquid diet. Meal orders from hospitalized youth were analyzed for nutritional content. Daily calories, fiber, protein, fat content, and sugar-sweetened beverages ordered were determined and compared with published dietary recommendations. Distribution analyses and odds ratios for meeting v. not meeting dietary recommendations were calculated for select factors and adjusted for hospital length of stay. 969 meal orders from 247 patients [13 (1, 26) [median (min, max)] years, 50% male, 47% Hispanic] at a tertiary care pediatric hospital were reviewed. Forty-four percent of daily meals exceeded caloric recommendations, 9% met fiber recommendations, 36% met fat recommendations, all met protein requirements, and 53% included sugar-sweetened beverages. Overweight/obese boys <13 y hospitalized ≤7 d were more likely to place meal orders exceeding daily caloric recommendations while Hispanic overweight/obese youth hospitalized ≤7 d were more likely to order sugar-sweetened beverages than inpatient counterparts. Pediatric hospital meal orders commonly do not meet dietary guidelines. Hospitals should encourage youth and families to order within nutritional guidelines to prevent additional health risk.

    In order to provide better advice for prevention of obesity and eating disorders among children, there is a need to have more knowledge of their dietary patterns. This study examined meal and snacking patterns of primary school children in Tehran. A total of 761 male and female primary school children from all educational areas in Tehran were recruited in a cross-sectional survey. The data was collected by interviewing the students and their mothers or caregivers. Information on food consumption patterns was collected by one 24-h-recall and one snack-oriented food frequency questionnaire which covered a period of 1 month. Means, standard deviations, frequencies, percentages, energy and nutrient analyzes and nutrient densities were reported. All of the students snacked at least once on the day of the survey. Snacks provided 38% of total energy intake by the students. Fruits and sweet snacks were consumed by almost all of the students during a week. Energy and most nutrient intakes from meals were greater than those consumed from snacks. Snacks had a higher density of fiber, carbohydrate, calcium, iron, vitamin C, riboflavin and thiamin and had a lower density of protein, fat and niacin, compared with main meals. Salty snacks such as extruded cheese curls (Cheetos) and chips were not consumed so often. Results provide detailed information about dietary patterns, which in turn enable development of targeted messages and/or interventions to improve nutritional status of school children.

    Full Text Available Abatement of odour emissions has become an important consideration to agricultural industries, including poultry production. The link between diet and odour emissions was studied in two experiments using Ross 308 male meat chickens reared in specially designed chambers in a climate controlled room. In the first experiment, two treatments were compared using three replicates of two birds per chamber. Two wheat-soy based treatment diets were formulated with or without canola seed, an ingredient rich in sulfur amino acids. Treatment 1 (T1 had 13.39 MJ/kg ME (as fed and used 60 g/kg canola seed without corn while Treatment 2 (T2 contained 12.90 MJ/kg ME (as fed and used 150 g/kg corn without canola seed. In the second experiment, birds were assigned to three dietary treatments of five replicates with five birds per replicate (chamber. The basal starter, grower and finisher diets in the control group (SBM group contained soybean meal in the range of 227–291 g/kg (as fed as the main protein source. The other treatments (CM and MBM groups contained either high levels of canola meal (174–190 g/kg or meat meal (74–110 g/kg at the expense of soybean meal. In both experiments, diets were isocaloric, isonitrogenous and contained similar digestible amino acid contents as per 2007 Aviagen Ross 308 guidelines. Emissions of odour were measured using Fourier transform infrared (FTIR spectroscopy. In both experiments, major odorous compounds detected included 2,3-butanedione (diacetyl, 2-butanone, dimethyl disulfide, methyl mercaptan, ethyl mercaptan, 2-butanol, 3-methyl-butanal, phenol and m-cresol. In the first experiment, T1 (with canola seed produced higher concentration of methyl mercaptan (P < 0.05 and lower diacetyl (P < 0.01 than T2. In the second experiment, methyl mercaptan emission was higher in SBM group (P = 0.01 and total elemental sulfur were higher in SBM and CM groups up to day 24 (P < 0.01. Results of these experiments

  14. EFFECT OF HEAT TREATMENT ON SOYBEAN PROTEIN SOLUBILITY

    Directory of Open Access Journals (Sweden)

    RODICA CĂPRIŢĂ

    2007-05-01

    Full Text Available The use of soybean products in animal feeds is limited due to the presence of antinutritional factors (ANF. Proper heat processing is required to destroy ANF naturally present in raw soybeans and to remove solvent remaining from the oil extraction process. Over and under toasting of soybean causes lower nutritional value. Excessive heat treatment causes Maillard reaction which affects the availability of lysine in particular and produces changes to the chemical structure of proteins resulting in a decrease of the nutritive value. The objective of this study was to evaluate the effect of heating time on the protein solubility. The investigation of the heating time on protein solubility in soybean meal (SBM revealed a negative correlation (r = -0.9596. Since the urease index is suitable only for detecting under processed SBM, the protein solubility is an important index for monitoring SBM quality.

    This study evaluated the influence of diets containing mealworm (Tenebrio molitor) meal in partial substitution of fishmeal on growth performance and immune responses of juvenile yellow catfish (Pelteobagrus fulvidraco). Four diets were formulated to contain 0 (the control diet), 9, 18 and 27 g mealworm meal per 100 g diet with 0%, 25%, 50% and 75% of fishmeal replacement, respectively. Yellow catfish were randomly divided into 4 groups with 3 replicates in each group. The fish in each group were fed with one of the four experimental diets for 5 weeks. Growth performance, plasma parameters (SOD, MDA, IgM, C3, lysozyme) and immune related genes (MHC II, IL-1, CypA, IgM, HE) of yellow catfish were determined at the end of the feeding trial, as well as 24 h post bacterial (Edwardsiella ictaluri) challenge. The present results showed that dietary inclusion of mealworm meal (MW) had no negative effects on the growth performance of the juvenile yellow catfish, compared to the control group. At the end of the feeding trial, plasma MDA contents of MW supplemented groups were significant lower than the control group. Plasma SOD activities increased significantly with the increasing dietary MW contents at the end of feeding trial (pre-challenge) and 24 h post challenge with E. ictaluri. Significant increase of plasma lysozyme activity was found in MW supplemented groups compared to the control group 24 h post bacterial challenge. Plasma IgM levels increased significantly with the increasing dietary MW contents at the end of feeding trial. Compared with the control group, the immune related genes of MHC II, IL-1, IgM and HE of the fish in the MW supplemented groups significantly upregulated pre-challenge or 24 h post bacterial challenge. Finally, it was observed that the survival rate of the 27% MW group was significant higher (P < 0.05) than the control group but was not significantly differed from the 18% MW group. The present results indicated that dietary

    In this study, we chose a carnivorous fish, turbot (Scophthalmus maximus L.), to examine its nutrient-sensing and metabolic responses after ingestion of diets with fishmeal (FM), or 45% of FM replaced by soyabean meal (34·6% dry diet) balanced with or without essential amino acids (EAA) to match the amino acid profile of FM diet for 30 d. After a 1-month feeding trial, fish growth, feed efficiency and nutrient retention were markedly reduced by soyabean meal-incorporated (SMI) diets. Compared with the FM diet, SMI led to a reduction of postprandial influx of free amino acids, hypoactivated target of rapamycin signalling and a hyperactivated amino acid response pathway after refeeding, a status associated with reduced protein synthesis, impaired postprandial glycolysis and lipogenesis. These differential effects were not ameliorated by matching an EAA profile of soyabean meal to that of the FM diet through dietary amino acid supplementation. Therefore, this study demonstrated that the FM diet and SMI diets led to distinct nutrient-sensing responses, which in turn modulated metabolism and determined the utilisation efficiency of diets. Our results provide a new molecular explanation for the role of nutrient sensing in the inferior performance of aquafeeds in which FM is replaced by soyabean meal.

    Full Text Available The effect of partial substitution of corn (-20% and soybean meal (-10% with buckwheat bran (+30% (Fagopyrum esculentum Moench in the diet of ISA-Brown hens was investigated in sixteen 74-week old hens, housed in couple wire cages and submitted to a 16 h light:8 h dark photoperiod. The following traits were measured: body weight, egg production, egg mass, egg quality, feed intake, feed conversion, comparative palatability of ingredients and digestibility of diet. χ2 and non-parametric tests were used for production rate and yolk color score, respectively. ANOVA was used for all other parameters. Comparative choice of buckwheat, corn and soy was checked under different forms in 3 free choice tests. Results show that egg production rate (43.3% vs 50.5%; P<0.05 and feed intake (78.3±0.68 eggs/hen d vs 87.8±0.68 eggs/hen d; P<0.05 increased with the partial introduction of buckwheat bran in the diet. There was no difference in feed conversion between treatments. Nutrient balance confirmed that AMEn of diet was deeply lowered by the buckwheat bran use (6.5 MJ/kg vs 10.1 MJ/kg , due to the high fibre content of buckwheat bran (263 g/kg. Maize was always the most preferred ingredient, buckwheat bran was consumed more than expected in absence of any preference, and soybean was the food least chosen. Buckwheat bran can be used as an ingredient feed for low-producing laying hens; it induces a feed-intake increase, partially balanced by improved egg-production rates and a tendency to better albumen Haugh units.

    School meals contribute substantially to overall energy and nutrient intake adequacy of children, but also play an important role in the development of child food habits and the socialisation process. Evidence shows that school based environmental actions, which include changes in school meals and school food policies related to increased availability and access to healthy foods and drinks while in the school are effective to foster healthy eating practices among children. A growing number of children engage in school meals. Available information to date shows that the quality of the food on offer is not always consistent with dietary guidelines. Vegetables and fish are served less often than desirable and excess added fats are used in food preparations. Norms and regulations are very detailed regarding food safety issues and administrative management of the service, including subcontracting of catering providers and care staff.

    The objective of this study was to investigate the effect of 3 soybean sources differing in fatty acid profile and processing method on productivity, milk composition, digestibility, rumen fermentation, and enteric methane emission in lactating dairy cows. The soybean sources were conventional, high-linoleic-acid variety extruded soybean meal (ESBM; 8.7% ether extract with 15% oleic and 54% linoleic acids); extruded Plenish (DuPont Pioneer, Johnston, IA), high-oleic-acid variety soybean meal (EPSBM; 8.4% ether extract with 73% oleic and 8% linoleic acids); and whole, heated Plenish soybeans (WPSB; 20.2% ether extract). The study involved 15 Holstein cows in a replicated 3 × 3 Latin square design experiment with three 28-d periods. The inclusion rate of the soybean sources in the diet was (dry matter basis) 17.1, 17.1, and 7.4% for ESBM, EPSBM, and WPSB, respectively, which resulted in ether extract concentration of the diets of 3.99, 3.94, and 4.18%, respectively. Compared with ESBM, the Plenish diets tended to increase dry matter intake and decreased feed efficiency (but had no effect on energy-corrected milk feed efficiency). The Plenish diets increased milk fat concentration on average by 5.6% and tended to increase milk fat yield, compared with ESBM. The WPSB diet tended to increased milk true protein compared with the extruded soybean meal diets. Treatments had no effect on rumen fermentation and enteric methane or carbon dioxide emissions, except pH was higher for WPSB versus EPSBM. The Plenish diets decreased the prevalence of Ruminococcus and increased that of Eubacterium and Treponema in whole ruminal contents. Total-tract apparent digestibility of organic matter and crude protein were decreased by WPSB compared with ESBM and EPSBM. Compared with the other treatments, urinary N excretion was increased by EPSBM and fecal N excretion was greater for WPSB. Treatments had marked effects on milk fatty acid profile. Generally, the Plenish diets increased mono

    The main aim of this study was to investigate the feasibility of using soybean meal added with papain to replace half of the fishmeal used in the moist pellets (49% fishmeal and 45% trash fish) developed by the Hong Kong Agriculture, Fisheries and Conservation Department (AFCD) for culturing marine fish. Gold-lined seabream (Rhabdosargus sarba), brown spotted grouper (Epinephelus bleekeri) and pompano (Trachinotus blochii) were farmed at one of the research stations (Kat-O) of AFCD, for a period of 340 days. Results indicated that diets containing papain resulted in better fish growth (reflected by relative weight gain and feed conversion ratio) than diets without papain. In general, wet weight gain of fish depends on the amount of papain added in diet rather than the diet composition. Soybean used in conjunction with papain also contributed to a more effective growth than fish fed with the moist pellets alone. A laboratory experiment (using tanks) was conducted to study the effects of the diets on concentrations of ammonia, nitrite and nitrate in the tank water. Results showed that concentrations of ammonia and nitrate were significantly lower (p marine fish and lower the adverse impact of trash fish and fishmeal on water quality of the mariculture zones.

    Full Text Available Two experiments were conducted to evaluate the effects of dietary oxidized poultry offal fat on the performance of broilers and on the oxidative stability of dark chicken meat. One hundred and sixty male chicks were fed a corn-soybean meal diet containing 4% fresh or oxidized poultry fat from 10 to 47 days of age. Fresh fat was stored frozen until diets were produced, and oxidized fat was obtained by electrical heating (110 to 120 ºC. Birds were slaughtered at 47 days of age, and carcass characteristics were measured. Skinless and deboned thigh meat was stored chilled during 12 days, and samples were periodically collected to assess their quality and oxidative stability. Dietary oxidized fat did not affect bird performance or carcass characteristics. During chilled storage, meat color (L*, a* and b* was not affected by dietary treatments; however, TBARS (Thiobarbituric Acid Reactive Substances values were higher (P<0.05 in thigh meat from chickens fed the oxidized fat, indicating that oxidative stability was adversely affected.

    The aim of this study was to estimate the dietary intake and major food sources of polyphenols in the Mediterranean healthy Eating, Aging and Lifestyles (MEAL) study cohort. A total of 1937 individuals (18 + y) of urban population of Catania, Italy, completed a validated 110-item food frequency questionnaire; Phenol-Explorer database was used to estimate polyphenol intake. Mean intake of polyphenols was 663.7 mg/d; the most abundant classes were phenolic acids (362.7 mg/d) and flavonoids (258.7 mg/d). The main dietary sources of total polyphenols were nuts, followed by tea and coffee as source of flavanols and hydroxycinnamic acids, respectively, fruits (i.e. cherries were sources of anthocyanins and citrus fruits of flavanones) and vegetables (i.e. artichokes and olives were sources of flavones and spinach and beans of flavonols); chocolate, red wine and pasta contributed to flavanols and tyrosols, respectively. These findings will be useful to assess the potential benefits of foods with high polyphenol content.

    Soybean is a common alternative protein source of plant origin in aquafeeds as it has a reasonably balanced amino acid profile and is widely available. This study aimed to investigate the influence of partial substitution of fish meal with soy meal on cytoprotective pathways and apoptosis in the digestive system of common dentex ( Dentex dentex ), using the activation of Hsp70, p38 MAPK, Bcl-2 and caspase-3. The experimental approach involved feeding of common dentex with three isoprotein and isoenergetic diets that contained fish meal as a protein source (FM), partial replacement of fish meal by soy meal 25% (SM25) and 40% (SM40) for 3 months. The SM40 diet induced Hsp70 activation only in the middle part of intestine. On the other hand, both SM25 and SM40 diets diminished the phosphorylation of p38 MAPK in the anterior and the middle part of intestine, whereas only SM25 induced p38 MAPK phosphorylation in the stomach. Moreover, a decrease in the levels of caspase-3 activity was observed in the middle and posterior intestine, as well as in the stomach after feeding with SM25 diets. Furthermore, Bcl-2 levels were increased by SM40 in the anterior and by SM25 in the middle part of intestine. SM25 and SM40 diets elicited a tissue and soy concentration specific cellular and cell protective response in the different parts of the digestive tract in common dentex.

    Full Text Available Satun Coastal Fisheries Research and Development Center, Muang, Satun 3Feeding management is crucial for feed efficiency, nutrient utilization, growth of cultured aquatic species and the amount of organic waste produced. This study aimed at investigating effects of two levels offeeding at two feeding frequencies on growth performance, feed efficiency and nitrogen and phosphorus loss in Asian seabass when fed diets with defatted soybean meal (SBM replacing fish meal. Three diets were formulated to contain defatted SBM to replace fish meal at 0, 10 and 20% of fish meal protein. Each diet wasgiven to the fish at either 4% of body weight (BW or to satiation. At each feeding level, the fish were fed at two feeding frequencies, once and twice daily. Fish with an average initial weight of 2.04±0.06 g/fish werereared for twelve weeks in the flow through system. Growth of fish reduced with an increasing amount of defatted SBM incorporated in diets as observed in other carnivorous species. Within groups of fish fed thesame diet, different growth performance and feed efficiency differed due to both feeding level and frequency. Weight gain of fish that were fed diet with defatted SBM replacing 10% of fish meal protein (diet 2until satiation was not significantly different from fish fed fish meal based diet at 4% BW. Furthermore, feeding fish the former diet twice daily resulted in an improvement of FCR, PER and PPV of fish to those ofthe fish fed fish meal based diet at satiation twice daily. Nitrogen and phosphorus loss was affected by diet, feeding level and frequency. Fish fed diet 2 until satiation twice daily lost nitrogen and phosphorus in theamount similar to that of fish fed fish meal based diet until satiation.

    The objective was to determine the energy concentration of a diverse array of dietary fat sources and, from these data, develop regression equations that explain differences based on chemical composition. A total of 120 Genetiporc 6.0 × Genetiporc F25 (PIC, Inc., Hendersonville, TN) individually housed barrows were studied for 56 d. These barrows (initial BW of 9.9 ± 0.6 kg) were randomly allotted to 1 of 15 dietary treatments. Each experimental diet included 95% of a corn-soybean meal basal diet plus 5% either corn starch or 1 of 14 dietary fat sources. The 14 dietary fat sources (animal-vegetable blend, canola oil, choice white grease source A, choice white grease source B, coconut oil, corn oil source A, corn oil source B, fish oil, flaxseed oil, palm oil, poultry fat, soybean oil source A, soybean oil source B, and tallow) were selected to provide a diverse and robust range of unsaturated fatty acid:SFA ratios (U:S). Pigs were limit-fed experimental diets from d 0 to 10 and from d 46 to 56, providing a 7-d adaption for fecal collection on d 7 to 10 (13 kg BW) and d 53 to 56 (50 kg BW). At 13 kg BW, the average energy content of the 14 sources was 8.42 Mcal DE/kg, 8.26 Mcal ME/kg, and 7.27 Mcal NE/kg. At 50 kg BW, the average energy content was 8.45 Mcal DE/kg, 8.28 Mcal ME/kg, and 7.29 Mcal NE/kg. At 13 kg BW, the variation of dietary fat DE content was explained by DE (Mcal/kg) = 9.363 + [0.097 × (FFA, %)] - [0.016 × omega-6:omega-3 fatty acids ratio] - [1.240 × (arachidic acid, %)] - [5.054 × (insoluble impurities, %)] + [0.014 × (palmitic acid, %)] ( = 0.008, = 0.82). At 50 kg BW, the variation of dietary fat DE content was explained by DE (Mcal/kg) = 8.357 + [0.189 × U:S] - [0.195 × (FFA, %)] - [6.768 × (behenic acid, %)] + [0.024 × (PUFA, %)] ( = 0.002, = 0.81). In summary, the chemical composition of dietary fat explained a large degree of the variation observed in the energy content of dietary fat sources at both 13 and 50 kg BW.

Nine treatments of M. oleifera pods:soybean were evaluated (100:0, 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 20:80 and 0:100, with a completely randomized design and three replications per treatment. An increase was observed in gas production with the increase of the soybean inclusion percentage; the true digestibility had a similar performance. On the contrary, the production of microbial biomass reached its higher value with the inclusion of 10% soybean. The addition of soybean is concluded to improve the digestibility of the M. oleifera pods, and the optimum utilization efficiency of this diet is reached with the inclusion of 10% soybean.

    Feed intake and diet composition appear to affect the body temperature of pigs. Two trials were conducted to analyse the effect of feed intake level and dietary protein content on the intestinal temperature (IT) of pigs housed under thermo neutral conditions. Ten pigs (64.1 ± 1.3 kg initial body weight) fitted with an ileal cannula were used. A thermometer set to register the IT at 5-min intervals was implanted into the ileum through the cannula. In both trials, the ambient temperature ranged from 19.1 to 21.6°C and the pigs were fed at 07:00 and 19:00 hr (same amount each time). In trial 1, the pigs were fed daily 1.2 or 1.8 kg of a wheat-soybean meal diet. The IT followed a similar pattern along a 24-hr period regardless the feed intake level. The IT rapidly increased up to 0.61 and 0.74°C after the morning meal and up to 0.53 and 0.47°C after the evening meal in pigs fed 1.2 and 1.8 kg/d respectively. The postprandial IT was higher in pigs fed 1.8 kg after each meal (p level. The postprandial IT did not differ between pigs fed the low protein or the high protein (p > .10). The IT rapidly increased up to 0.66 and 0.62°C after the morning meal in pigs fed the high- and low-protein diet (p  .10).

    This study evaluated the effects on lamb growth, carcass traits and meat quality of replacing conventional soybean meal in the diet with alternative legume grains. Twenty-eight male lambs of Comisana breed weighing 16.9 ± 2.7 kg at weaning (66 ± 6 days old) were assigned to one of four diets. Until slaughter at 129 ± 6 days of age, each group received ad libitum pelleted alfalfa hay and concentrates differing in the source of protein: chickpea, faba bean, pea or soybean meal. Lambs fed chickpea showed higher dry matter and protein intakes from concentrate than those fed soybean. Lambs' growth, carcass weight and net dressing percentage did not vary by protein source, although chickpea lambs had more perirenal and pelvic fat than those in the soybean group. Diet did not affect chemical composition, colour, thawing and cooking losses, tenderness, and sensory properties of meat. Chickpea increased trans-vaccenic and linoleic acid, and chickpea and faba bean increased the isomers of conjugated linoleic acid. Legume grains can completely replace soybean meal in concentrate, resulting in lamb carcasses and meat of comparable quality. Chickpea leads to an increase in feed intake of lambs and in fat depots in the carcass, and a more beneficial fatty acid profile. Copyright © 2012 Society of Chemical Industry.

    Far more attention has been paid to the microbes in our feces than the microbes in our food. Research efforts dedicated to the microbes that we eat have historically been focused on a fairly narrow range of species, namely those which cause disease and those which are thought to confer some "probiotic" health benefit. Little is known about the effects of ingested microbial communities that are present in typical American diets, and even the basic questions of which microbes, how many of them, and how much they vary from diet to diet and meal to meal, have not been answered. We characterized the microbiota of three different dietary patterns in order to estimate: the average total amount of daily microbes ingested via food and beverages, and their composition in three daily meal plans representing three different dietary patterns. The three dietary patterns analyzed were: (1) the Average American (AMERICAN): focused on convenience foods, (2) USDA recommended (USDA): emphasizing fruits and vegetables, lean meat, dairy, and whole grains, and (3) Vegan (VEGAN): excluding all animal products. Meals were prepared in a home kitchen or purchased at restaurants and blended, followed by microbial analysis including aerobic, anaerobic, yeast and mold plate counts as well as 16S rRNA PCR survey analysis. Based on plate counts, the USDA meal plan had the highest total amount of microbes at 1.3 × 10(9) CFU per day, followed by the VEGAN meal plan and the AMERICAN meal plan at 6 × 10(6) and 1.4 × 10(6) CFU per day respectively. There was no significant difference in diversity among the three dietary patterns. Individual meals clustered based on taxonomic composition independent of dietary pattern. For example, meals that were abundant in Lactic Acid Bacteria were from all three dietary patterns. Some taxonomic groups were correlated with the nutritional content of the meals. Predictive metagenome analysis using PICRUSt indicated differences in some functional KEGG categories

    Soybean meal (SBM) is a product generated from the manufacture of soybean oil and has the potential for use as a source of fermentable sugars for ethanol production or as a protein source for animal feeds. Knowing the levels of nitrogen available from ammonium is a necessary element of the ethanolic fermentation process while identifying the levels of essential amino acids such as lysine is important in determining usage as a feed source. As such the purpose of this study was to quantify total nitrogen and ammonium in the liquid fraction of hydrolyzed SBM and to evaluate total and bioavailable lysine in the solid fraction of the hydrolyzed SBM. The effects of acid concentration, cellulase and β-glucosidase on total and ammonium nitrogen were studied with analysis indicating that higher acid concentrations increased nitrogen compounds with ammonium concentrations ranging from 0.20 to 1.24 g L -1 while enzymatic treatments did not significantly increase nitrogen levels. Total and bioavailable lysine was quantified by use of an auxotrophic gfpmut3 E.coli whole-cell bioassay organism incapable of lysine biosynthesis. Acid and enzymatic treatments were applied with lysine bioavailability increasing from a base of 82% for untreated SBM to up to 97%. Our results demonstrated that SBM has the potential to serve in ethanolic fermentation and as an optimal source essential amino acid lysine.

    A 70-day growth trial was conducted with postlarvae 12 (PL12) Pacific white shrimp (Litopenaeus vannamei) to study the suitability of soybean meal and oil originating from a single-celled microorganism (thraustochytrid) as fishmeal and fish oil substitutes in practical diets for L. vannamei. The growth, survival rate and immune characteristics were evaluated. Seven experimental diets were designed with soybean meal used as the primary protein source; each formulation contained 33% crude protein and 8% lipid. Fish oil was completely substituted with 3% soybean oil and meals originating from single-celled heterotrophs rich in docosahexaenoic acid (DHA) and arachidonic acid (ARA) were added at different concentrations. A commercial shrimp feed was used as the control diet. The final weights and survival rates of the shrimp were not significantly different among all treatments. However, shrimp raised on diets supplemented with marine algal meals rich in DHA and ARA showed significant improvement in immune parameters, such as total hemocyte count, phenoloxidase activity, superoxide dismutase activity, and bactericidal activity. Additionally, the survival rate after challenge with Vibrio harveyi was increased. These findings demonstrated that substitution of thraustochytrid-derived meals as an alternative to fish-based ingredients in shrimp diets provided similar growth rates while increasing the immune parameters and providing vibriosis resistance.

    Full Text Available OBJECTIVE: The aim of this study was to evaluate the quality of meals consumed by workers from São Paulo according to eating location. METHODS: This cross-sectional study used the 24-hour recall to collect dietary data from 815 workers, including where the meal was consumed, and then grouped the meals by eating location: home, workplace cafeteria, and restaurant. Meal quality was assessed according to energy content and density, fiber density, and proportion of macronutrients, 10 food groups, and from sugar-sweetened beverages. These indicators and their respective eating locations were then included in linear regression models adjusted for gender, age, and education level. RESULTS: Meals consumed at workplace cafeterias had lower energy density, higher fiber density, and higher proportions of vegetables, fruits, and beans than those consumed at home. However, away-from-home meals contain more sugars, sweets, fats, and oils. CONCLUSION: Eating location influences diet quality, so dietary surveys should assess meals consumed away from home more thoroughly since meal quality varies greatly by food service.

    Two studies were conducted to determine whether soybean meal (SBM) use in nursery pig diets can be increased by superdosing with phytase. In Exp. 1, 2,550 pigs (BW of 5.54 ± 0.09 kg) were used to evaluate the optimal level of phytase in low- or high-SBM diets. Two SBM levels (low and high) and 4 phytase doses (0, 1,250, 2,500, and 3,750 phytase units [FTU]/kg) were combined to create 8 dietary treatments in a 2 × 4 factorial arrangement. Pigs were fed a 3-phase feeding program, with each period being 10, 10, and 22 d, respectively. Inclusion of low and high SBM was 15.0 and 25.0%, respectively, for Phase 1; 19.0 and 29.0%, respectively, for Phase 2; and 32.5% for the common Phase 3 diet. Pigs fed diets with high SBM had improved G:F for Phase 1 and 2 and overall ( Phytase quadratically improved G:F during Phase 3 and overall ( phytase dose being 2,500 FTU/kg. High-SBM diets tended ( = 0.09) to decrease stool firmness (determined daily from d 1 to 10) only on d 2. In Exp. 2, 2,112 pigs (BW of 5.99 ± 0.10 kg) were used to evaluate the impact of high levels of SBM and phytase on performance, stool firmness, mortality, and morbidity in weaned pigs originating from a porcine reproductive and respiratory syndrome (PRRS) virus-positive sow farm. Pigs were fed a 3-phase feeding program as in Exp. 1. Three levels of SBM (low, medium, or high) and 2 phytase levels (600 or 2,600 FTU) were combined to create 6 dietary treatments in a 3 × 2 factorial arrangement. Inclusion of SBM was 15.0, 22.5, and 30.0% for Phase 1 and 20.0, 27.5, and 35.0% for Phase 2 for low, medium, and high SBM, respectively, and 29.0% for the common Phase 3 diet. Inclusion of SBM did not affect growth performance. The percentage of pigs removed for medical treatment linearly declined with increasing SBM levels ( = 0.04). High-SBM diets tended ( phytase tended ( phytase at superdose levels can improve growth performance independently from the level of SBM in the diet.

    Family meals have been associated with higher diet quality and reduced risk of obesity in children. Observational studies of the family meal have been employed with increasing frequency, yet there is currently no tool available for measuring the healthfulness of food served during the meal. Here we present the development and validation of the Healthy Meal Index (HMI), a novel tool for scoring the healthfulness of foods served to children during a meal, as well as sociodemographic predictors of meal scores. Parents of 233 children, aged 4-8 years, self-recorded three home dinners. A research assistant obtained a list of foods available during the meal (meal report) via phone call on the night of each video-recorded meal. This meal report was coded into component food groups. Subsequently, meals were scored based on the availability of more healthy "Adequacy foods" and the absence of "Moderation foods", (of which reduced consumption is recommended, according to pediatric dietary guidelines). Adjusted linear regression tested the association of sociodemographic characteristics with HMI scores. A validation study was conducted in a separate sample of 133 children with detailed meal data. In adjusted models, female children had higher HMI Moderation scores (p = 0.02), but did not differ in HMI Adequacy or Total scores. Parents with more education served meals with higher HMI Adequacy (p = 0.001) and Total scores (p = 0.001), though no significant difference was seen in HMI Moderation score (p = 0.21). The validation study demonstrated that the HMI was highly correlated with servings of foods and nutrients estimated from observations conducted by research staff. The HMI is a valuable tool for measuring the quality of meals served to children. Copyright © 2016. Published by Elsevier Ltd.

    Full Text Available Abstract Background Safe and effective weight control strategies are needed to stem the current obesity epidemic. The objective of this one-year study was to document and compare the macronutrient and micronutrient levels in the foods chosen by women following two different weight reduction interventions. Methods Ninety-six generally healthy overweight or obese women (ages 25–50 years; BMI 25–35 kg/m2 were randomized into a Traditional Food group (TFG or a Meal Replacement Group (MRG incorporating 1–2 meal replacement drinks or bars per day. Both groups had an energy-restricted goal of 5400 kJ/day. Dietary intake data was obtained using 3-Day Food records kept by the subjects at baseline, 6 months and one-year. For more uniform comparisons between groups, each diet intervention consisted of 18 small group sessions led by the same Registered Dietitian. Results Weight loss for the 73% (n = 70 completing this one-year study was not significantly different between the groups, but was significantly different (p ≤ .05 within each group with a mean (± standard deviation weight loss of -6.1 ± 6.7 kg (TFG, n = 35 vs -5.0 ± 4.9 kg (MRG, n = 35. Both groups had macronutrient (Carbohydrate:Protein:Fat ratios that were within the ranges recommended (50:19:31, TFG vs 55:16:29, MRG. Their reported reduced energy intake was similar (5729 ± 1424 kJ, TFG vs 5993 ± 2016 kJ, MRG. There was an improved dietary intake pattern in both groups as indicated by decreased intake of saturated fat (≤ 10%, cholesterol ( Conclusion In this one-year university-based intervention, both dietitian-led groups successfully lost weight while improving overall dietary adequacy. The group incorporating fortified meal replacements tended to have a more adequate essential nutrient intake compared to the group following a more traditional food group diet. This study supports the need to incorporate fortified foods and/or dietary supplements while following an energy

  14. The microbes we eat: abundance and taxonomy of microbes consumed in a day’s worth of meals for three diet types

    Full Text Available Far more attention has been paid to the microbes in our feces than the microbes in our food. Research efforts dedicated to the microbes that we eat have historically been focused on a fairly narrow range of species, namely those which cause disease and those which are thought to confer some “probiotic” health benefit. Little is known about the effects of ingested microbial communities that are present in typical American diets, and even the basic questions of which microbes, how many of them, and how much they vary from diet to diet and meal to meal, have not been answered.We characterized the microbiota of three different dietary patterns in order to estimate: the average total amount of daily microbes ingested via food and beverages, and their composition in three daily meal plans representing three different dietary patterns. The three dietary patterns analyzed were: (1 the Average American (AMERICAN: focused on convenience foods, (2 USDA recommended (USDA: emphasizing fruits and vegetables, lean meat, dairy, and whole grains, and (3 Vegan (VEGAN: excluding all animal products. Meals were prepared in a home kitchen or purchased at restaurants and blended, followed by microbial analysis including aerobic, anaerobic, yeast and mold plate counts as well as 16S rRNA PCR survey analysis.Based on plate counts, the USDA meal plan had the highest total amount of microbes at 1.3 × 109 CFU per day, followed by the VEGAN meal plan and the AMERICAN meal plan at 6 × 106 and 1.4 × 106 CFU per day respectively. There was no significant difference in diversity among the three dietary patterns. Individual meals clustered based on taxonomic composition independent of dietary pattern. For example, meals that were abundant in Lactic Acid Bacteria were from all three dietary patterns. Some taxonomic groups were correlated with the nutritional content of the meals. Predictive metagenome analysis using PICRUSt indicated differences in some functional KEGG

    Family meals have been associated with improved dietary quality in children and adolescents, and yet very little is known about family meals beyond their frequency. Specific aspects of the breakfast, lunch, and dinner meal environments were described and compared, and the associations with overall diet quality were investigated. Data on food intake and meal environments were obtained in northern Ontario, southern Ontario, and Nova Scotia grades six, seven, and eight classrooms over the 2005 to 2006 school year. Specific aspects of the meal environments described were where the meal was consumed, with whom participants consumed each meal, who prepared the meal, and where the food was originally purchased. Diet quality was assessed using the Canadian version of the Healthy Eating Index. Cluster K-means procedures were used to classify into groups observations about the four meal environment variables. Three, eight, and six clusters of meal environments were identified for breakfast, lunch, and dinner, respectively. Diet quality was negatively associated with consuming/ purchasing meals outside the home, and with skipping breakfast, lunch, and/or dinner. Results have immediate relevance for family-based and/or school programs and policies aimed at educating and feeding children and adolescents.

    The aim of the study was to evaluate the feasibility of replacing soybean meal (SBM) with Tenebrio molitor larvae (TML) meal in broiler diets. A total of 80 30-d-old male Shaver brown broilers were divided into two groups fed on two isoproteic and isoenergetic diets differing for protein source (SBM vs. TML). Up to 62 d of age, body weight and feed intake were recorded weekly and body weight gain, feed conversion ratio (FCR), protein efficiency ratio (PER) and European efficiency factor (EEF) were calculated. At 62 d, blood samples were collected from 16 birds/group for evaluation of blood profiles. Feed intake was not different between groups considering the entire period of the trial. The FCR was more favourable in the TML than SBM group from 46 d of age and in the entire period of the trial (4.13 vs. 3.62). The PER was higher in the SBM than in the TML group (1.92 vs. 1.37) while the EEF was higher in broilers fed on the TML diet (132.6 vs. 156.2). Albumin-to-globulin ratio was higher in broilers fed on SBM than in the other group (0.44 vs. 0.30). aspartate aminotransferase and alanine aminotransferase were higher in TML than SBM (195.1 vs. 178.6 U/l and 82.07 vs. 46.71 U/l, respectively). Uric acid was higher in broilers fed on SBM than TML (5.40 vs. 4.16 mg/dl). TML did not affect feed intake and growth rate of broilers from 30 to 62 d of age when compared to an isoproteic and isoenergetic SBM diet, but FCR of the TML group was more favourable than that of the SBM group. The lowest albumin-to-globulin ratio in broilers fed on TML suggests a higher immune response, probably due to the prebiotic effects of chitin.

    Two experiments were conducted to investigate the use of sorghum, cottonseed meal and millet in broiler diets and their interaction when they are used simultaneously. In Experiment 1, a corn-soybean meal control diet was compared with eight experimental treatments based on low tannin sorghum (S30, S45 and S60), cottonseed meal (CM15, CM40) or both ingredients included in the same diet (S30/CM40, S45/CM25 and S60CM15). Results showed that BW gain was not affected by the inclusion of sorghum or cottonseed meal. However, feed intake tended to be affected by the cereal type with the highest values with sorghum-based diets. Feed conversion ratio increased (Pdigestibility (%) of protein and energy with the cottonseed meal and sorghum/cottonseed meal-based diets having lower protein and energy digestibility compared with corn-based diets. In Experiment 2, a control diet was compared with six diets in which corn was substituted at 60%, 80% or 100% by either sorghum or millet and other three diets with simultaneous inclusion of these two ingredients (S30/M30, S40/M40, S50/M50). Single or combined inclusion of sorghum and millet resulted in similar feed intake and growth performance as the control diet. Apparent ileal digestibility of protein and energy was higher with millet-based diets (Pdigestibility of protein in sorghum and millet-based diets tended to decrease linearly with the increasing level of substitution. Sorghum-based diets resulted in lower total tract digestibility of fat compared with millet and sorghum/millet-based diets (Pdigestibility of starch were obtained with the control diet and millet-based diets compared with the sorghum-based treatments. Results of the two experiments suggest that broiler growth performance was not affected by the dietary level of sorghum, millet or cottonseed meal. Nutrient digestion can, however, be affected by these feed ingredients.

    An epizootic of salmonellosis in a dairy herd started 2 days after the feeding of a new shipment of medicinal-smelling soybean meal. Clinical findings consisted of diarrhea or fever (greater than 39 C), or both, and markedly decreased milk production. The attack rate was 73% in lactating cows, 3% in calves, and 0% in nonlactating cows. There were no deaths, but 1 cow aborted a late-term fetus. Salmonella anatum was isolated from feces, milk, pharynx, uterine fluid, haylage, and bird droppings from a hayfield. The epidemiologic findings suggested that haylage contaminated by wild birds and improperly stored in a silo was the source of infection and that the precipitating event was ingestion of spoiled soybean meal.

    A growth experiment was conducted on cobia ( Rachycentron canadum, initial weight 108.2 g ± 3.0 g) to investigate the effects of dietary corn gluten meal (CGM) levels on the fish growth, whole body composition and protein metabolism in relation to specific gene expression. Five isonitrogenous (crude protein 45%) and isoenergetic (gross energy 20 kJ g-1) practical diets were formulated by replacing 0% (the control), 17.5%, 35.0%, 52.5%, and 70.0% of fish meal (FM) protein with CGM protein. No significant differences were observed in the survival, feed intake (FI), specific growth rate (SGR), feed efficiency (FE) and protein productive value (PPV) among fish fed diets with 0%, 17.5%, 35.0%, and 52.5% of CGM protein. However, these indices were significantly lower in fish fed the diet with 70.0% of CGM protein than those in fish fed the control diet ( P cobia. The present results might be useful for developing cost effective and sustainable cobia dietary formulations.

    Full Text Available Abstract Background The impact of salmonella contaminated feed ingredients on the risk for spreading salmonella to pigs was assessed in response to two incidences when salmonella was spread by feed from two feed mills to 78 swine producing herds. Methods The assessment was based on results from the salmonella surveillance of feed ingredients before introduction to feed mills and from HACCP - based surveillance of the feed mills. Results from the mills of the Company (A that produced the salmonella contaminated feed, were by the Chi. Square test compared to the results from all the other (B - E feed producers registered in Sweden. Isolated serovars were compared to serovars from human cases of salmonellosis. Results Salmonella (28 serovars was frequently isolated from imported consignments of soybean meal (14.6% and rape seed meal (10.0%. Company A largely imported soybean meal from crushing plants with a history of unknown or frequent salmonella contamination. The risk for consignments of vegetable proteins to be salmonella contaminated was 2.4 times (P Conclusions Salmonella contaminated feed ingredients are an important source for introducing salmonella into the feed and food chain. Effective HACCP-based control and associated corrective actions are required to prevent salmonella contamination of feed. Efforts should be taken to prevent salmonella contamination already at the crushing plants. This is challenge for the EU - feed industry due to the fact that 98% of the use of soybean/meal, an essential feed ingredient, is imported from crushing plants of third countries usually with an unknown salmonella status.

Methods A total of 432 32-wk-old laying hens were randomly divided into 6 treatments with 6 replicates of 12 birds each. The birds were fed diets containing SBM, LCSM100, or DRM100 individually or in combination with an equal amount of crude protein (CP (LCSM50, DRM50, and LCSM50-DRM50. The experimental diets, which were isocaloric (metabolizable energy, 11.11 MJ/kg and isonitrogenous (CP, 16.5%, had similar digestible amino acid profile. The feeding trial lasted 12 weeks. Results The daily egg mass was decreased in the LCSM100 and LCSM50-DRM50 groups (p0.05 and showed increased yolk color at the end of the trial (p0.05. Conclusion Together, our results suggest that the LCSM100 or DRM100 diets may produce the adverse effects on laying performance and egg quality after feeding for 8 more weeks. The 100.0 g/kg LCSM diet or the148.7 g/kg DRM diet has no adverse effects on laying performance and egg quality.

    Many xeric organisms maintain water balance by relying on dietary and metabolic water rather than free water, even when free water may be available. For such organisms, hydric state may influence foraging decisions, since meal consumption is meeting both energy and water demands. To understand foraging decisions it is vital to understand the role of dietary water in maintaining water balance. We investigated whether meal consumption was sufficient to maintain water balance in captive Gila monsters (Heloderma suspectum) at varying levels of dehydration. Gila monsters could not maintain water balance over long time scales through meal consumption alone. Animals fed a single meal took no longer to dehydrate than controls when both groups were deprived of free water. Additionally, meal consumption imparts an acute short-term hydric cost regardless of hydration state. Meal consumption typically resulted in a significant elevation in osmolality at 6 h post-feeding, and plasma osmolality never fell below pre-feeding levels despite high water content (~70%) of meals. These results failed to support our hypothesis that dietary water is valuable to Gila monsters during seasonal drought. When considered in conjunction with previous research, these results demonstrate that Gila monsters, unlike many xeric species, are heavily reliant on seasonal rainfall and the resulting free-standing water to maintain water balance.

    In order to investigate the effect of dietary soybean phospholipid supplement on hepatic and serum indexes relevant to fatty liver hemorrhagic syndrome (FLHS) in layers, 135 300-day-old Hyline Brown layers were randomly divided into three groups (control, pathology and prevention), and each group had 45 layers with three replicates. Birds in the three groups were respectively fed the control diet, high-energy low-protein diet and high-energy high-protein diet affixed with 3% soybean phospholipid instead of maize. Results showed in the 30th day, birds' livers in the pathology group became yellowish, enlarged in size and had hemorrhagic spots, while the prevention and control groups' layers did not have such pathological changes.

    This systematic review aimed to synthesise information on indices developed to evaluate nutritional quality of meals. A strategy for systematic search of the literature was developed using keywords related to assessment of meal quality. Databases searched included ScienceDirect, PubMed, Lilacs, SciELO, Scopus, Cochrane, Embase and Google Scholar. The literature search resulted in seven different meal quality indices. Each article was analysed in order to identify the following items: authors, country, year, study design, population characteristics, type of meal evaluated, dietary assessment method, characteristics evaluated (nutrients or food items), score range, index components, nutritional references, correlations performed, validation and relationship with an outcome (if existing). Two studies developed instruments to assess the quality of breakfast, three analysed lunch, one evaluated dinner and one was applied to all types of meals and snacks. All meal quality indices reviewed were based on the evaluation of presence or absence of food groups and relative contributions of nutrients, according to food-based guidelines or nutrient references, adapting the daily dietary recommendations to one specific meal. Most of the indices included three items as components for meal quality assessment: (I) total fat or some specific type of fat, (II) fruits and vegetables and (III) cereals or whole grains. This systematic review indicates aspects that need further research, particularly the numerous approaches to assessing meals considering different foods and nutrients, and the need for validation studies of meal indices.

    Full Text Available Dietary protein sources can have profound effects on host-microbe interactions in the gut that are critically important for immune resilience. However more knowledge is needed to assess the impact of different protein sources on gut and animal health. Thirty-six wildtype male C57BL/6J mice of 35 d age (n = 6/group; mean ± SEM body weight 21.9 ± 0.25 g were randomly assigned to groups fed for four weeks with semi synthetic diets prepared with one of the following protein sources containing (300 g/kg as fed basis: soybean meal (SBM, casein, partially delactosed whey powder, spray dried plasma protein, wheat gluten meal and yellow meal worm. At the end of the experiment, mice were sacrificed to collect ileal tissue to acquire gene expression data, and mammalian (mechanistic target of rapamycin (mTOR activity, ileal digesta to study changes in microbiota and serum to measure cytokines and chemokines. By genome-wide transcriptome analysis, we identified fourteen high level regulatory genes that are strongly affected in SBM-fed mice compared to the other experimental groups. They mostly related to the mTOR pathway. In addition, an increased (P < 0.05 concentration of granulocyte colony-stimulating factor was observed in serum of SBM-fed mice compared to other dietary groups. Moreover, by 16S rRNA sequencing, we observed that SBM-fed mice had higher (P < 0.05 abundances of Bacteroidales family S24-7, compared to the other dietary groups. We showed that measurements of genome-wide expression and microbiota composition in the mouse ileum reveal divergent responses to diets containing different protein sources, in particular for a diet based on SBM.

    Full Text Available Abstract Background Several techniques are available to study gene function, but many are less than ideal for soybean. Reverse genetics, a relatively new approach, can be utilized to identify novel mutations in candidate genes; this technique has not produced an allelic variant with a confirmed phenotype in soybean. Soybean raffinose synthase genes and microsomal omega-6 fatty acid desaturase genes were screened for novel alleles in mutagenized soybean populations. Results Four mutations in independent lines were identified in the raffinose synthase gene RS2; two mutations resulted in amino acid mutations and one resulted in an altered seed oligosaccharide phenotype. The resulting phenotype was an increase in seed sucrose levels as well as a decrease in both raffinose and stachyose seed oligosaccharide levels. Three mutations in independent lines were identified in the omega-6 fatty acid desaturase gene FAD2-1A; all three mutations resulted in missense amino acid mutations and one resulted in an altered seed fatty acid profile that led to an increase in oleic acid and a decrease in linoleic acid in the seed oil. Conclusion The oligosaccharide phenotype controlled by the novel RS2 allele is similar to previously observed seed oligosaccharide phenotypes in RS2 mutant (PI 200508 allele-containing lines. Due to the anti-nutritional characteristics of raffinose and stachyose, this represents a positive change in seed composition. The fatty acid phenotype controlled by the novel FAD2-1A allele controls an increase in oleic acid in the seed oil, a phenotype also observed in a line previously characterized to have a null allele of the FAD2-1A gene. Molecular marker assays were developed to reliably detect the inheritance of the mutant alleles and can be used in efficient breeding for these desired seed phenotypes. Our results serve as the first demonstration of the identification of soybean mutants controlling seed phenotypes discovered through the

    A meta-analysis was conducted (i) to evaluate broiler response to partial or total substitution of corn by sorghum and millet and (ii) to determine the effect of soybean meal replacement by cottonseed meal in broiler diet. The database included 190 treatments from 29 experiments published from 1990 to 2013. Bird responses to an experimental diet were calculated relative to the control (Experimental-Control), and were submitted to mixed-effect models. Results showed that diets containing millet led to similar performance as the corn-based ones for all parameters, whereas sorghum-based diets decreased growth performance. No major effect of the level of substitution was observed with millet or cottonseed meal. No effect of the level of substitution of sorghum on feed intake was found; however, growth performance decreased when the level of substitution of corn by sorghum increased. Cottonseed meal was substituted to soybean meal up to 40% and found to increase feed intake while reducing growth performance. Young birds were not more sensitive to these ingredients than older birds since there was no negative effect of these ingredients on performance in the starter phase. Results obtained for sorghum pointed out the necessity to find technological improvements that will increase the utilization of these feedstuffs in broiler diet. An additional work is scheduled to validate these statistical results in vivo and to evaluate the interactions induced with the simultaneous inclusions of sorghum, millet and cottonseed meal in broiler feeding.

    Full Text Available Three experiments were carried out to determine the nutritional values and evaluate the performance of piglets fed on canola meal. In experiment I, a digestibility assay was conducted using fourteen barrow pigs, with an initial body weight of 20.62±3.30 kg. The evaluated feedstuff was canola meal, with a level of 250 g/kg in the basal diet (corn + soybean meal-based. The experimental unit consisted of one pig, with a total of seven experimental units per diet. The values as (fed basis of digestible (DE and metabolizable (ME energy of canola meal were 2,995 kcal/kg and 2,796 kcal/kg, respectively. In experiment II, ileal digestibility assays were carried out to determine the apparent and true ileal digestibility coefficient and digestible amino acids. Three crossbred pigs were used, with a BW of 38.6±1.98 kg. The treatments consisted of two diets, with a single source of protein (canola meal and one protein-free diet (OFD. The values of digestible amino acids in canola meal were as follows: lysine: 11.8 g/kg; methionine+cystine: 9.1 g/kg; threonine: 7.9 g/kg; tryptophan: 2.4 g/kg; leucine: 15.7 g/kg; and isoleucine: 8.7 g/kg. In experiment III, 60 piglets (BW= 15.08±0.72 kg to 30.26±2.78 kg were allotted in a completely randomized design. The treatments consisted of four diets with increasing levels of canola meal (50, 100, 150 and 200 g/kg, six replicates and experimental unit consisted of two pigs. Additionally, a control diet was formulated containing 0.0 g/kg CM. Regression analysis indicates that there was no effect (P?0.05 of the level of canola meal inclusion on pigs performance. The performance results suggest that it is feasible to use up to 200 g/kg of canola meal in starting pigs diet, without impairing performance and the feeding cost.

    The aim of this research was to study the effect of soybean meal (SBM) heat procedures on growth performance of broiler chickens. A trial was carried out using 200 male Ross 308 strain chickens during 3 feeding periods (starter, grower and finisher, 42 days). The experiment was based on a completely randomized design with 5 treatments giving 4 replications of 10 broilers per treatment. Treatments consisted on: T1 (control, un-processed SBM), T2 (autoclaved SBM: 121 degree centigrade, 20 min), T3 (autoclaved SBM: 121 degree centigrade, 30 min), T4 (roasted SBM: 120 degree centigrade, 20 min) and T5 (microwaved SBM: 46 degree centigrade, 540 watt, 7 min). Growth performance of animals was examined by determining body weight (BW), body weight grain (BWG), feed intake (FI) and feed conversion rate (FCR). Higher BW (p<0.05) and BWG (p<0.05) and lower FCR (p<0.05) were found in broiler chickens fed heat processed SBM diets compared to those fed a raw SBM diet, probably due to higher nutrient availability. However, no differences were found among heat SBM procedures (autoclaving, roasting and microwaving) on growth performance of animals for the starter, grower and finisher periods. From the results of this experiment, it is concluded that further research needs to be developed to establish the effect of temperature-time heat procedures on nutritive value of SBM in terms of levels of anti-nutritional factors (trypsin inhibitor activity and phytic acid) and amino acids profile and its influence on growth performance of broilers.

    Six hundred and forty one-day-old layer chicks were used to investigate the effect of replacing soybean meal with undecorticated sunflower seed meal protein for protein at 0, 25, 50, and 75% levels. Diets were without enzyme supplementation or with enzyme supplementation with four replications of twenty birds. Growth performance and nutrient utilization were determined. Proximate composition of the undecorticated sunflower seed meal used revealed that undecorticated sunflower seed meal contained 925.9, 204.5, 336.2, 215.1, 52.0 and 192.2g/kg dry matter, crude protein, ether extract, crude fibre, ash and soluble carbohydrates, respectively. Results showed that the final weight of 484.4 g/bird was obtained for birds on 75% undecorticated sunflower seed meal diet, while the lowest value of 472.2g/bird was obtained for birds on 25% undecorticated sunflower seed meal diet. Weight gain per bird per day was not significantly (P > 0.05) affected as the level of undecorticated sunflower seed meal increased in the diets. Feed intake per bird per day increased (P meal inclusion in the diet. However, enzyme supplementation of the diets showed marked (P meal inclusion in the diet while crude protein digestibility progressively reduced (P meal increased in the diet. Ash digestibility values were, however, increased (P meal increased in the diets. Birds on enzyme-supplemented diets consistently showed superior (P meal in the diets of layer chicks showed a similar body weight gain/bird/day with the control. Undecorticated sunflower seed meal used in this study is a good source of crude protein, ether extract, and amino acids and had the potential to serve as feeding stuffs as replacement for soybeans. The nutritive value of undecorticated sunflower seed meal was improved for layer chicks with exogenous enzyme supplementation. © 2015 Poultry Science Association Inc.

    To study how different meals contribute to intakes of fruits, vegetables, fish and whole grains in a group of Norwegian adults and in subgroups of this population. Moreover, to investigate the consequences of skipping the meal contributing most to the intake of each food group (main contributing meal). Cross-sectional dietary survey in Norwegian adults. Dietary data were collected using two non-consecutive telephone-administered 24 h recalls. The recorded meal types were breakfast, lunch, dinner, supper/evening meal and snacks. Nationwide, Norway (2010-2011). Adults aged 18-70 years (n 1787). Dinner was the main contributing meal for fish and vegetables, while snacks were the main contributing meal for fruit intake. For whole grains, breakfast was the main contributing meal. The main contributing meal did not change for any of the food groups when studying subgroups of the participants according to intake of each food group, educational level or age. A substantially lower intake of the food groups in question was found on days when the main contributing meal was skipped. Intakes of fruits, vegetables, fish and whole grains largely depend on one meal type. Inclusion of these foods in other meals in addition to the main contributing meal, preferably replacing energy-dense nutrient-poor foods, should be promoted.

    Iron absorption from adequate Filipino meals representing the three major island groups of the Philippines (Luzon, Visayas, and Mindanao) was studied using double isotope extrinsic tag method. Mean iron absorption of the one-day meal for Metro Manila was 6.6 +- 1.26%. Central Visayas, 6.3 +- 1.15% and Southern Mindanao, 6.4 +- 1.19%. Comparison between meals (breakfast, lunch, dinner) for each region as well as one-day meal for the three regions showed no significant differences (P>0.01). Correlation tests done between iron absorption and the following iron enhancers: ascorbic acid, amount of fish, meat or poultry; and inhibitors: phytic acid and tannic acid, did not give significant results. The overall average of 6.4 +- 1.20% may be used as the iron absorption level from an adequate Filipino meal. This value can be considered as one of the bases for arriving at recommended dietary allowances for iron among Filipinos instead of the 10% iron absorption assumed in 1976.

    Full Text Available ABSTRACT: This study evaluated the effects of millet and corn oil additions to sorghum-based diets on the performance, carcass yields and prime cuts (i.e., wings, breasts, thighs and drumsticks and the relative weights of edible offal (i.e., gizzard, heart, and liver of broiler chickens. A total of 684 Hubbard Flex chickens, including 342 broilers of each sex, were housed. The design was completely randomized, and the following diets were supplied: A sorghum and soybean meal + soybean oil (control; B sorghum and soybean meal + corn oil; and C sorghum and soybean meal + millet and soybean oil. Six replicates with 38 birds each (19 males and 19 females were evaluated regarding each experimental diet. At 14, 21, 35 and 42 days of age, the feed intake, weight gain, feed conversion and viability of the chickens were evaluated. At 42 days, the live weight, carcass yield, prime cuts and relative weight of the edible offal were measured. The dietary inclusion of either millet or corn oil did not affect any of the parameters. In conclusion, additions of millet and corn oil to sorghum-based diets of broilers do not compromise poultry performance.

    There are two kinds of iron in the diet with respect to the mechanism of absorption, heme-iron which is present as haemoglobin or myoglobin in meat and blood products, and, non-heme iron which is the main source of dietary iron. The bioavailability of the non-heme food iron is much lower than heme-iron. Vegetarian diets contain only non-heme iron. Iron intake from vegetarian meals are generally satisfied with the requirements, however, the bioavailabilities for non-heme iron is determined not only by iron content byt also the balance between different dietary factors enhancing and inhibiting iron absorption. The main enhancing factor in vegetarian meals is ascorbic acid in fruits and vegetables, inhibitors are phytate in cereals and grains, and tannins in some spices and vegetables. It has been reported that iron deficiency is one of the common micronutrient problems associated with unplanned vegetarian diets. In the present study the absorption of non-heme iron was measured from 2 vegetarian meals containing considerable amounts of phytate and tannin. The extrinsic tay method ( 59 Fe/ 55 Fe) was used to labelled the non-heme iron. The mean percentage absorption of non-heme iron from both meals was slightly different due to differences in their dietary contents. Their initial percentages iron absorption were apparent low (3.5% and 4.1%), however, the absorption progressively increased with increase in the level of ascorbic acid, 2-3 times with 100 mg and 4-5 times with 200 mg of ascorbic acid. The average amount of iron absorbed per 2000 kcal increased from 0.37 mg to 0.86 mg and 1.45 mg with the addition of 100 mg and 200 mg ascorbic acid respectively (p < 0.001). Considering the limited caloric intakes and the iron content in the meals, the amount of iron absorbed from vegetarian meals without ascorbic acid was not able to meet certain requirements for children, adolescents and menstruating women. The minimal requirement for dietary iron needed to be absorbed is

    The purpose of this quality improvement project was to redesign a hospital meal delivery process in order to shorten the time between blood glucose monitoring and corresponding insulin administration and improve glycemic control. This process change redesigned the workflow of the dietary and nursing departments. Modifications included nursing, rather than dietary, delivering meal trays to patients receiving insulin. Dietary marked the appropriate meal trays and phoned each unit prior to arrival on the unit. The process change was trialed on 2 acute care units prior to implementation hospital wide. Elapsed time between blood glucose monitoring and insulin administration was analyzed before and after process change as well as evaluation of glucometrics: percentage of patients with blood glucose between 70 and 180 mg/dL (percent perfect), blood glucose greater than 300 mg/dL (extreme hyperglycemia), and blood glucose less than 70 mg/dL (hypoglycemia). Percent perfect glucose results improved from 45% to 53%, extreme hyperglycemia (blood glucose >300 mg/dL) fell from 11.7% to 5%. Hypoglycemia demonstrated a downward trend line, demonstrating that with improving glycemic control hypoglycemia rates did not increase. Percentage of patients receiving meal insulin within 30 minutes of blood glucose check increased from 35% to 73%. In the hospital, numerous obstacles were present that interfered with on-time meal insulin delivery. Establishing a meal delivery process with the nurse performing the premeal blood glucose check, delivering the meal, and administering the insulin improves overall blood glucose control. Nurse-led process improvement of blood glucose monitoring, meal tray delivery, and insulin administration does lead to improved glycemic control for the inpatient population.

    The Smart-card-based Automatic Meal Record system for company cafeterias (AutoMealRecord system) was recently developed and used to monitor employee eating habits. The system could be a unique nutrition assessment tool for automatically monitoring the meal purchases of all employees, although it only focuses on company cafeterias and has never been validated. Before starting an interventional study, we tested the reliability of the data collected by the system using the data mining approach. The AutoMealRecord data were examined to determine if it could predict current obesity. All data used in this study (n = 899) were collected by a major electric company based in Tokyo, which has been operating the AutoMealRecord system for several years. We analyzed dietary patterns by principal component analysis using data from the system and extracted 5 major dietary patterns: healthy, traditional Japanese, Chinese, Japanese noodles, and pasta. The ability to predict current body mass index (BMI) with dietary preference was assessed with multiple linear regression analyses, and in the current study, BMI was positively correlated with male gender, preference for "Japanese noodles," mean energy intake, protein content, and frequency of body measurement at a body measurement booth in the cafeteria. There was a negative correlation with age, dietary fiber, and lunchtime cafeteria use (R(2) = 0.22). This regression model predicted "would-be obese" participants (BMI >or= 23) with 68.8% accuracy by leave-one-out cross validation. This shows that there was sufficient predictability of BMI based on data from the AutoMealRecord System. We conclude that the AutoMealRecord system is valuable for further consideration as a health care intervention tool. Copyright 2010 Elsevier Inc. All rights reserved.

    The traditionally classified nutritionally non-essential amino acids are now known to be insufficiently synthesized for maximal growth and optimal health in piglets. This study determined the effects of dietary supplementation with an amino acid blend (AAB; glutamate:glutamine:glycine:arginine:N-acetylcysteine = 5:2:2:1:0.5) on piglet growth performance and intestinal functions. Sixteen piglets (24-day-old) were randomly assigned to a corn and soybean meal-based diet supplemented with 0.99% alanine (isonitrogenous control) or 1% AAB. On day 20 of the trial, blood and intestinal tissue samples were obtained from piglets. Compared with the control, AAB supplementation reduced (P sodium-independent amino acid transporters (b 0,+ AT and y + LAT1), aquaporin (AQP) 3, AQP8, AQP10, nuclear factor erythroid 2-related factor 2 and glutathione S-transferase omega-2, and protein abundances of AQP3, AQP4, claudin-1, occludin and myxovirus resistance 1; and the numbers of Bifidobacterium genus and Lactobacillus genus in the colon digesta. Collectively, these comprehensive results indicate that dietary AAB supplementation plays an important role in improving piglet growth and intestinal function.

    The study evaluated the partial substitution of soybean meal by faba beans (18%) or peas (20%) as additional protein sources in diets destined for typical Italian heavy pig production. It compared animal performances, meat quality, the presence of residual anti-nutritional factors (ANF) and phytoestrogens in plasma and meat and the possible effects on pig health, by evaluating oxidative, inflammatory and pro-atherogenic markers. The results showed that the productive performances, expressed as body weight and feed conversion ratio, of pigs fed with faba bean and pea diets were similar to those of pigs fed only the soybean meal. Meat quality of pigs fed with the three diets was similar in colour, water-holding capacity, tenderness and chemical composition. Despite the higher levels of phytoestrogen in the plasma of pigs fed only the soybean meal, phytoestrogen concentration in the muscle was equivalent to that of animals fed diets with faba beans, whereas pigs fed a diet with peas showed a lower concentration. Inflammation and pro-atherogenic parameters did not show significant differences among the three diets. Overall, the partial substitution of soybean meal by faba beans appears more interesting than with peas, particularly in relation to the higher amount of polyphenols in the diet and the highest concentration of phytoestrogens found in the plasma and muscle of animals, while the pyrimidine anti-nutritional compounds present in the diet did not appear to accumulate and had no effect on the growth performance of animals.

Antigenotoxic activity of dietary coconut oil was very much greater than dietary soybean oil.Germ cell genotoxicity of each genotoxin was also reduced when male mice fed the 18 % coconut oil diet were used. When male mice treated with the genotoxin was mated with virgin females, fertility index was increased in the group fed with coconut oil diet. Percentage dead implants was reduced. The antigenotoxic activity of dietary coconut oil on germ cells far exceeds that of dietary soybean oil.Dietary restriction of coconut oil diets enhanced the antigenotoxic activity of coconut oil in bone marrow cells and germs cells.Among the triacylglycerols of coconut oil, trilaurin gave the best antigenotoxic activity in bone marrow cells. Trilaurin is the major triacylglycerol in coconut oil.

    Full Text Available The paper presents the results obtained in a study on the comparative evaluation of the effect of a diet with safflower oil and flax seeds compared to a control soybean oil diet given to layers on the bioproductive effects, egg characteristics and yolk fatty acids profile. The trial involved 32 Lowman Brown layers during the age period 23- 28 weeks (1 week of accommodation and 4 experimental weeks. The layers, assigned to 2 groups (16 layers/group, 4 layers/cage received diets based on corn, wheat and soybean meal. The diets differed by the source of fatty acids: soybean oil for the control group (SO; safflower oil and flax seeds for SSO+FS. The diets were supplemented with 250 ppm vitamin E. Twelve eggs per group were collected randomly 10 and 30 days, respectively, after the beginning of the experiment. The paper presents comparative data on the: average egg weight, egg component (egg shell, yolk, egg white weight, intensity of yolk colour (Hoffman – La Roche colour range, yolk protein, fat yolk pH (measured one week after collection, the eggs being kept at 50C and yolk fatty acids. All data show that the profile of yolk unsaturated fatty acids can be handled quite easily by the nature of the dietary fats, their level of inclusion and their dietary ratio.

    Two experiments using soybean meal (SBM) or canola meal (CM) were conducted to investigate whether the choice of digestibility marker influenced the apparent ileal digestibility (AID) or standardized ileal digestibility (SID) of N and AA in diets supplemented with phytase. In each experiment, 18 barrows fitted with T-cannulas at the ileocecal junction were assigned to 3 diets consisting of a N-free diet to determine endogenous losses of N and AA, a semipurified diet (SBM in Exp. 1 or CM in Exp. 2), and the semipurified diet supplemented with phytase at 1,000 phytase units/kg. Three digestibility markers including acid-insoluble ash (AIA), chromic oxide (Cr2O3), and titanium dioxide (TiO2) were added to each diet at 3 g/kg. Each diet was fed for 7 d, consisting of a 5-d adjustment and a 2-d collection of ileal digesta. In both studies, basal ileal endogenous losses determined with Cr2O3 as a digestibility marker were lower (Pdigestibility markers. Using SBM as the protein source in Exp. 1, there was no interaction between phytase and digestibility marker on AID or SID of AA. The AID of N and AA in SBM using AIA as a digestibility marker tended to be lower (Pdigestibility markers. Phytase supplementation increased (Pdigestibility marker tended to be associated with lower (Pdigestibility marker and phytase. Phytase supplementation had effects (Pdigestibility marker. With Cr2O3 or TiO2 as the digestibility marker in the CM diets, phytase supplementation increased (Pdigestibility marker. In contrast, there were no clear improvements in AA digestibility from phytase supplementation for SBM. Phytase effects on AID or SID of AA were dependent on the digestibility marker used in diets when CM was used as the protein source but not when SBM was used as the protein source. Therefore, AA digestibility response to phytase supplementation may depend on the protein being evaluated as well as the choice of digestibility marker.

    1. The effects of alfalfa meal on carcase quality and fat metabolism of Muscovy duck were evaluated. The objective of this research was to establish whether alfalfa meal can reduce fat content and improve carcase quality of Muscovy duck. Animal products with a high fat content present a risk factor for many diseases. Reducing fat content in poultry products is an important goal for the poultry industry. 2. A total of 240 14-d-old white Muscovy ducks were selected and randomly allocated to 1 of 4 dietary treatments containing 0, 3, 6, and 9% of alfalfa meal for 5 weeks. Growth performances were recorded and carcase characteristics and lipid parameters were analysed. 3. Results showed that 3, 6, and 9% alfalfa meal in diet had no significant effects on growth performance of Muscovy ducks from 14 to 49 d of age. Ducks given 3, 6, and 9% alfalfa meal had significantly higher dressing percentage and lower abdominal fat percentage compared with those given no alfalfa meal. Ducks given 9% alfalfa meal had higher breast meat percentage compared with those given no alfalfa meal. The concentrations of triglyceride, total cholesterol, low density lipoprotein (LDL), very low density lipoprotein (VLDL) and free fatty acid in serum of ducks fed on alfalfa meal decreased. Alfalfa meal in the diet decreased abdominal fat percentage and improved carcase traits of Muscovy duck. 4. The study showed that dietary alfalfa meal decreased abdominal fat percentage and improved carcase traits, without an adverse effect on performance.

    A commercial soy protein isolate (SPI) was further processed in an attempt to understand how a diet based on SPI can cause decreased iron retention by the rat from a separately administered casein-based test meal. Groups of eight rats were fed either a casein-based diet or a diet based on SPI. The acid-precipitated SPI was incorporated into diets as such, after neutralization, after 60% (v/v) ethanol extraction and neutralization, or after 60% ethanol exposure and neutralization. All dietary SPI was heat-treated by exposure to steam at 108 degrees C for 30 min. Rats were fed their respective diets, each containing 25 mg Fe/kg, for 13 d, and then all rats were fed a 59 Fe-radiolabeled 2.5-g casein test meal containing 64 micrograms of iron. Ingested radioactivity was determined following the meal, and retained radioactivity over the subsequent 10-d period. Absorption was not distinguishable for groups fed the casein-based (78.3 ± 3.6%) and the ethanol-extracted, SPI-based diet (80.2 ± 5.4%). Absorption was lower (P less than 0.01) for groups fed each of the other SPI-based diets: SPI as such (68.3 ± 8.9%), neutralized SPI (69.8 ± 5.0%) and ethanol-exposed SPI (67.6 ± 4.8%). An ethanol-extractable component of SPI may be responsible for decreased iron absorption by animals fed SPI prior to a radiolabeled test meal

The forced feeding method was utilized, by using 24 adult Leghorn roosters with means 2.35 ± 165 g. The rooster was considered as an experimental unit and each feed was given to 6 roosters (6 replicates, two replicates in each time. Simultaneously, 6 roosters were kept in fasting for determination of the endogenous and metabolic losses. Before the experimental period, each rooster was maintained without any feed for 24 hours for emptying of the digestive tract and then forced to ingest 30 grams of the test feed. For that reason, four collections of excreta were done every 12 hours, to avoid fermentation. At the end of this period, the feeds and also the excreta were homogenized for analysis of dry matter, nitrogen and gross energy and then calculated the values of energy. The values of EMVn calculated were then contrasted with values of EMVn estimated from the prediction equations presented in the national literature for groups of feeds similar to those of the present work. The values of EMVn of the soybean meals ranged from 2531 to 2730 Kcal/kg of DM and those of toasted and micronized whole soybean were 3732 and 4027 Kcal/kg of DM, respectively. For the whole soybeans and soybean meals, the equation which best estimated the values of energy were TMEn = 2690.62 - 40.87ADF + 19.96NDF + 63.09EE. In general, the equations tested in the present work shown not good estimates of the values of EMVn, so, they are not adequate to be utilized as a

    The purpose of this study was to determine the meal- and snack-eating frequency and the nutritional composition of each eating occasion of Canadian high-performance athletes during training. Athletes from 8 Canadian Sport Centres prospectively completed 3-d dietary records including all food, fluid, and supplements consumed. The time of consumption and whether the consumption was a meal or snack were also identified. The dietary records were analyzed for energy (kcal) and macronutrient intake (carbohydrate, protein, and fat) and compared based on gender, age, meal vs. snack, and training vs. rest days. Three hundred twenty-four athletic subjects (64% female and 36% male) completed the study. On average, the athletes ate 4.8 ± 0.8 times daily. Nearly all athletes consumed 3 daily meals of breakfast (98.9%), lunch (97.9%), and dinner (98.7%), with few having snacks: 57%, 71.6%, and 58.1% of athletes consumed an a.m., p.m., and evening snack, respectively. Training-day meal frequency did not differ from that during rest days; however, fewer snacks were consumed on rest days. A.m. and p.m. snacks were consumed significantly more often on training days than rest days. Overall, snacks contributed 24.3% of total daily energy intake. Few dietary variations were discovered between genders, while the youngest athletes (<18 yr) ate less often, especially their morning snack, than the older athletes. In conclusion, Canadian high-performance athletes self-adjusted their energy intakes on training vs. rest days primarily by snacking less and reducing their carbohydrate and protein intakes on rest days, yet they consistently ate regular meals.

    Few studies have looked at the relationship between family meals and adult weight and health behaviors. The current study investigates the association between frequency of family meals and mothers’ and fathers’ body mass index (BMI), dietary intake, dieting behaviors and binge eating. Data from Project F-EAT (Families and Eating and Activity in Teens) were used for the current analysis. Socio-economically and racially/ethnically diverse mothers and fathers (n = 3,488) of adolescents participating in a multi-level population-based study (EAT 2010) completed surveys mailed to their homes. Predicted means or probabilities were calculated for each outcome variable at each level of family meal frequency. Interactions between race/ethnicity and marital status with family meals were evaluated in all models. Overall, results indicated that having more frequent family meals was associated with increased consumption of fruits and vegetables for mothers and fathers, after adjusting for age, educational attainment, marital status and race/ethnicity. Other findings including less fast food intake for fathers and fewer dieting and binge eating behaviors for mothers were significantly associated with family meal frequency, but not consistently across all family meal categories or with BMI. Interactions by race/ethnicity and marital status were non-significant, indicating that family meals may be important for more healthful dietary intake across race and marital status. Future research should confirm findings in longitudinal analyses to identify temporality and strength of associations. PMID:22425759

    Two experiments were conducted to investigate using alfalfa leaf meal (ALM; 22% CP, DM basis) in beef cattle diets. In Exp. 1, a total of 24 late-gestation Angus heifers (initial BW 470 +/- 9 kg) were blocked by BW, calving date, and BCS to 1 of 4 dietary treatments in a randomized complete block design. All heifers were offered a basal hay diet (7.4% CP and 67.6% NDF, DM basis). Treatments were arranged as a 2 x 2 factorial consisting of CP supplied at 100 or 112.5% of the recommended daily intake using either soybean meal (SBM) or ALM as the supplemental protein source. Treatments were fed for an average of 100 d before calving. Total DMI was unaffected by supplemental protein source, although heifers consumed more (P Feeding 112.5% of recommended CP to heifers increased precalving rate of BW gain (P = 0.004) and DM digestibility (P = 0.003). Protein source did not affect DM digestibility (P = 0.17). Neither supplemental protein source nor protein amount affected changes in BCS or calving traits. In Exp. 2, replicates of treatments were conducted over 2 consecutive years at 2 locations in northern Minnesota to determine the effects of including ALM in creep-fed supplements on nursing calf performance, supplement BW gain efficiency (GF; BW gain over control/supplement intake), and cow performance. Treatments were control (no supplement), ALM supplement (58% ALM, as-fed basis), or a wheat middling- and soybean hull-based supplement (MIDD). Milk intake (estimated by the weigh-suckle-weigh technique) was similar among treatments. Creep-fed calves had greater (P creep feed DMI than those offered ALM (2.6 vs. 1.3 kg/d, respectively). A year x treatment interaction was noted for GF (P = 0.02). In yr 1, GF for calves offered ALM was greater (P = 0.006) than GF for calves offered MIDD, but in yr 2, there were no differences. Alfalfa leaf meal may substitute for SBM in beef heifer wintering diets and conventional creep feed ingredients. When included in creep feed diets

    An experiment was conducted to estimate the true ileal digestibility of P in wheat, sorghum, soybean meal, and corn distiller's dried grains with solubles (DDGS) in broiler chickens. Four semipurified diets were formulated from each ingredient (wheat and sorghum: 236.5, 473, 709.5, and 946 g/kg; soybean meal and corn DDGS: 135, 270, 405, and 540 g/kg) to contain graded concentrations of nonphytate P. The experiment was conducted as a randomized complete block design with 4 weight blocks of 16 cages each (5 birds per cage). A total of 320 21-d-old broilers (Ross 308) were assigned to the 16 test diets with 4 replicates per diet. Apparent ileal digestibility coefficients of P were determined by the indicator method and the linear regression method was used to determine the true P digestibility coefficients. The results showed that the apparent ileal P digestibility coefficients of wheat-based diets were not influenced (P>0.05) by increasing dietary P concentrations, whereas those of diets based on sorghum, soybean meal, and corn DDGS differed (Pdigestibility in broilers fed diets with soybean meal and corn DDGS linearly (Pdigestibility coefficients of wheat, sorghum, soybean meal, and corn DDGS were determined to be 0.464, 0.331, 0.798, and 0.727, respectively. Ileal endogenous P losses in birds fed diets with wheat, soybean meal, and corn DDGS were estimated to be 0.080, 0.609, and 0.418 g/kg DMI, respectively. In birds fed sorghum-based diets, endogenous P losses were estimated to be negative (-0.087 g/kg DMI). True digestible P contents of wheat, sorghum, soybean meal, and corn DDGS were determined to be 1.49, 0.78, 5.16, and 5.94 g/kg, respectively. The corresponding nonphytate P contents in wheat, sorghum, soybean meal, and corn DDGS were 1.11, 0.55, 2.15, and 4.36 g/kg, respectively. These differences between digestible P and nonphytate P contents may be suggestive, at least in part, of overestimation of P digestibility under the calcium-deficient conditions

    Full Text Available Seed phytate is a repository of P and minerals in soybean [ (L. Merr.] seeds that limits P and mineral bioavailability for monogastric animals (e.g., humans, swine [], and poultry [especially chicken, ] due to insufficient digestive tract phytase activity. We previously identified epistatic recessive mutations affecting two paralogous adenosine triphosphate-binding cassette phytic acid transporter genes (one a nonsense mutation in and the other a missense mutation in as the molecular genetic basis in the ethyl methanesulfonate (EMS-induced mutant low phytate soybean line M153. An additional mutant low phytate line, M766, contained one single nucleotide polymorphism within the ninth intron of the locus as well as a nonsense mutation in . The objectives of this research were to clarify the genetics underlying the low phytate phenotype in line M766 and to determine P partitioning in new combinations of mutant alleles from M766 and M153. Inheritance of nonsense alleles affecting both ( genes (one from M153 and one from M766 led to the production of viable seeds that contained transgressive reductions in total seed phytate and significantly higher levels of inorganic phosphate than has been reported for nontransgenic soybean material and will allow efficient molecular selection of soybeans with even greater reductions of phytate for improved quality soybean meal.

    Hydroponic cultivation allows the control of environmental conditions, saves irrigation water, increases productivity, and prevents plant infections. The use of this technique for large commodities such as soybean is not a relevant issue on fertile soils, but hydroponic soybean cultivation could provide proteins and oil in adverse environmental conditions. In this paper, the compositions of four cultivars of soybean seeds and their derivates, soy milk and okara, grown hydroponically were compared to that of the same cultivar obtained from soil cultivation in an open field. Besides proximal composition, the concentrations of phytic acid and isoflavones were monitored in the seeds, soy milk, and okara. Results demonstrated that, independent from the cultivar, hydroponic compared to soil cultivation promoted the accumulation of fats (from 17.37 to 21.94 g/100 g dry matter) and total dietary fiber (from 21.67 to 28.46 g/100 g dry matter) and reduced isoflavones concentration (from 17.04 to 7.66 mg/kg dry matter), whereas protein concentration was unaffected. The differences found in seed composition were confirmed in the respective okara products, but the effect of cultivation system was not significant looking at the soy milk composition. Data showed that hydroponic cultivation improved the nutritional quality of soybean seeds with regard to fats and dietary fiber. They also suggest that specific cultivars should be selected to obtain the desired nutritional features of the soybean raw material depending on its final destination.

    Full Text Available The aim of the study was to evaluate the frequency of breakfast and other meal consumption by adolescents and to assess the relationship between the first and the last meal consumption and sex, body mass index (BMI, and middle school and high school students’ education level. The study was conducted in 2013–2014 among 3009 students (1658 girls and 1351 boys from middle s and high schools in Krakow and Silesia (Poland. The data was obtained from questionnaires that were analyzed with a logistic regression model for measurable and dichotomous variables. Breakfast consumers were seen to eat other meals (second breakfast, lunch, dessert, supper significantly more often than breakfast skippers. The main meal consumption habits depend on sex and change as adolescents age. Being a girl and a high school student predisposed participants to skip breakfast and supper more often. The BMI of breakfast consumers does not differ significantly from the BMI of breakfast skippers, so BMI might thus not be a sufficient marker of breakfast consumption regularity and dietary habits in an adolescent group. The importance of regularly eaten meals, especially breakfast, together with adequate daily dietary energy intake are beneficial for physical and psychological development and cannot be overestimated in nutritional education and it is necessary to promote healthy eating behavior for well-being in later adult life.

    The aim of the study was to evaluate the frequency of breakfast and other meal consumption by adolescents and to assess the relationship between the first and the last meal consumption and sex, body mass index (BMI), and middle school and high school students' education level. The study was conducted in 2013-2014 among 3009 students (1658 girls and 1351 boys) from middle s and high schools in Krakow and Silesia (Poland). The data was obtained from questionnaires that were analyzed with a logistic regression model for measurable and dichotomous variables. Breakfast consumers were seen to eat other meals (second breakfast, lunch, dessert, supper) significantly more often than breakfast skippers. The main meal consumption habits depend on sex and change as adolescents age. Being a girl and a high school student predisposed participants to skip breakfast and supper more often. The BMI of breakfast consumers does not differ significantly from the BMI of breakfast skippers, so BMI might thus not be a sufficient marker of breakfast consumption regularity and dietary habits in an adolescent group.

    Insects are currently being considered as a novel protein source for animal feeds, because they contain a large amount of protein. The larvae of Tenebrio molitor (TM) have been shown to be an acceptable protein source for broiler chickens in terms of growth performance, but till now, no data on histological or intestinal morphometric features have been reported. This study has had the aim of evaluating the effects of dietary TM inclusion on the performance, welfare, intestinal morphology and histological features of free-range chickens. A total of 140 medium-growing hybrid female chickens were free-range reared and randomly allotted to two dietary treatments: (i) a control group and (ii) a TM group, in which TM meal was included at 75 g/kg. Each group consisted of five pens as replicates, with 14 chicks per pen. Growth performance, haematological and serum parameters and welfare indicators were evaluated, and the animals were slaughtered at the age of 97 days. Two birds per pen (10 birds/treatment) were submitted to histological (liver, spleen, thymus, bursa of Fabricius, kidney, heart, glandular stomach and gut) and morphometric (duodenum, jejunum and ileum) investigations. The inclusion of TM did not affect the growth performance, haematological or serum parameters. The morphometric and histological features were not significantly affected either, thus suggesting no influence on nutrient metabolization, performance or animal health. Glandular stomach alterations (chronic flogosis with epithelial squamous metaplasia) were considered paraphysiological in relation to free-range farming. The observed chronic intestinal flogosis, with concomitant activation of the lymphoid tissue, was probably due to previous parasitic infections, which are very frequently detected in free-range chickens. In conclusion, the findings of this study show that yellow mealworm inclusion does not affect the welfare, productive performances or morphological features of free-range chickens

    Full Text Available This study aimed to investigate the impact of dietary calcium (Ca and phosphorus (P, derived from bone meal, on the feline urine composition and the urinary pH, allowing a risk assessment for the formation of calcium oxalate (CaOx uroliths in cats. Eight healthy adult cats received 3 canned diets, containing 12.2 (A, 18.5 (B and 27.0 g Ca/kg dry matter (C and 16.1 (A, 17.6 (B and 21.1 g P/kg dry matter (C. Each diet was fed over 17 days. After a 7 dayś adaptation period, urine and faeces were collected over 2×4 days (with a two-day rest between, and blood samples were taken. Urinary and faecal minerals, urinary oxalate (Ox, the urinary pH and the concentrations of serum Ca, phosphate and parathyroid hormone (PTH were analyzed. Moreover, the urine was microscopically examined for CaOx uroliths. The results demonstrated that increasing levels of dietary Ca led to decreased serum PTH and Ca and increased faecal Ca and P concentrations, but did not affect the urinary Ca or Ox concentrations or the urinary fasting pH. The urinary postprandial pH slightly increased when the diet C was compared to the diet B. No CaOx crystals were detected in the urine of the cats. In conclusion, urinary Ca excretion in cats seems to be widely independent of the dietary Ca levels when Ca is added as bone meal to a typical canned diet, implicating that raw materials with higher contents of bones are of subordinate importance as risk factors for the formation of urinary CaOx crystals.

    Full Text Available Soybean [Glycine max (L. Merr.] is the number one oil and protein crop in the United States, but the seed contains several anti-nutritional factors that are toxic to both humans and livestock. RNA interference technology has become an increasingly popular technique in gene silencing because it allows for both temporal and spatial targeting of specific genes. The objective of this research is to use RNA-mediated gene silencing to down-regulate the soybean gene raffinose synthase 2 (RS2, to reduce total raffinose content in mature seed. Raffinose is a trisaccharide that is indigestible to humans and monogastric animals, and as monogastric animals are the largest consumers of soy products, reducing raffinose would improve the nutritional quality of soybean. An RNAi construct targeting RS2 was designed, cloned, and transformed to the soybean genome via Agrobacterium-mediated transformation. Resulting plants were analyzed for the presence and number of copies of the transgene by PCR and Southern blot. The efficiency of mRNA silencing was confirmed by real-time quantitative PCR. Total raffinose content was determined by HPLC analysis. Transgenic plant lines were recovered that exhibited dramatically reduced levels of raffinose in mature seed, and these lines were further analyzed for other phenotypes such as development and yield. Additionally, a precision-fed rooster assay was conducted to measure the true metabolizable energy (TME in full-fat soybean meal made from the wild-type or transgenic low-raffinose soybean lines. Transgenic low-raffinose soy had a measured TME of 2,703 kcal/kg, an increase as compared with 2,411 kcal/kg for wild-type. As low digestible energy is a major limiting factor in the percent of soybean meal that can be used in poultry diets, these results may substantiate the use of higher concentrations of low-raffinose, full-fat soy in formulated livestock diets.

    An experiment was conducted to determine protein quality in processed protein sources using the content of AA, -methylisourea (OMIU)-reactive Lys, Maillard reaction products (MRP), and cross-link products; the standardized ileal digestibility (SID) of CP and AA; and growth performance in growing pigs as criteria. Differences in protein quality were created by secondary toasting (at 95°C for 30 min) of soybean meal (SBM) and rapeseed meal (RSM) in the presence of lignosulfonate resulting in processed SBM (pSBM) and processed RSM (pRSM). The processing treatment was used as a model for overprocessed protein sources. Ten growing pigs were each fed 1 of the 4 diets containing SBM, pSBM, RSM, or pRSM in each of 3 periods. Ileal chyme was collected at the end of each period and analyzed for CP, AA, and OMIU-reactive Lys. Diets were analyzed for furosine and carboxymethyllysine (CML) as an indicator for MRP and lysinoalanine (LAL), which is a cross-link product. The SBM and RSM diets contained furosine, CML, and LAL, indicating that the Maillard reaction and cross-linking had taken place in SBM and RSM, presumably during the oil extraction/desolventizing process. The amounts of furosine, CML, and LAL were elevated in pSBM and pRSM due to further processing. Processing resulted in a reduction in total and OMIU-reactive Lys contents and a decrease in G:F from 0.52 to 0.42 for SBM and 0.46 to 0.39 for RSM ( = 0.006), SID of CP from 83.9 to 71.6% for SBM and 74.9 to 64.6% for RSM ( < 0.001), and SID of AA ( < 0.001), with the largest effects for total and OMIU-reactive Lys. The effects of processing could be substantial and should be taken into account when using processed protein sources in diets for growing pigs. The extent of protein damage may be assessed by additional analyses of MRP and cross-link products.

    Soybean is an important protein source for both humans and animals. However, soybean proteins are relatively poor in the sulfur-containing amino acids, cysteine and methionine. Improving the content of endogenous proteins rich in sulfur-containing amino acids could enhance the nutritive value of soybean meal. Leginsulin, a cysteine-rich peptide, predominantly accumulates in Asian soybean accessions but not in most North American cultivars. By screening diverse soybean accessions from the USDA Soybean Germplasm Collection, we were able to identify one plant introduction, PI 427138, as a high-protein line with relatively high amounts of both elemental sulfur and leginsulin. We introgressed these desirable traits from PI 427138 into an experimental line with the aim of improving the overall protein content and quality of seed proteins. Biochemical characterization of inbred progenies from the cross of LD00-3309 with PI 427138 grown at six locations revealed stable ingression of high protein, high elemental sulfur, and high leginsulin accumulation. Comparison of soybean seed proteins resolved by high-resolution 2-D gel electrophoresis in combination with Delta2D image analysis software revealed preferential accumulation of a few glycinin subunits contributed to the increased protein content in the introgressed lines. Amino acid analysis revealed that even though the leginsulin introgressed lines had higher protein, leginsulin, and elemental sulfur, the overall concentration of sulfur-containing amino acids was not significantly altered when compared with the parental lines. The experimental soybean lines developed during this study (Leg-3, Leg-7, and Leg-8) lack A5, A4, and B3 glycinin subunits and could be utilized in breeding programs to develop high-quality tofu cultivars.

    Changes in ftty acid patterns of lipids in serum and erythrocytes induced by dietary fats and in vitro incorporation of fatty acids into erythrocyte membranes were investigated with pigs. On feeding various diets, it was found that fatty acid composition of serum and erythrocytes could be modified and altered toward the fatty acid pattern of the diet. In vitro, the incorporation of labelled fatty acids into erythrocyte membranes was accelerated by the addition of cofactors such as lysolecithin, CoA and ATP. Dietary fats also had certain effects on the incorporation of fatty acids into erythrocyte membranes. Erythrocytes, collected from the blood of pigs fed corn oil, incorporated and also released more labelled linoleate than those of pigs fed hydrogenated soybean oil. Palmitic acid was more slowly incorporated into erythrocyte membranes than linoleic acid in the pigs fed both a commercial chow and scheduled meals, indicating selective esterification of fatty acids in the erythrocyte membranes.

    The establishment of a healthy gastrointestinal milieu may not only offer an opportunity to reduce swine production costs but could also open the way for a lifetime of human health improvement. This study investigates the effects of feeding soluble fibre from flaxseed meal-containing diet (FM) and insoluble fibre from oat hulls-containing diet (OH) on histomorphological characteristics, digesta- and mucosa-associated microbiota and their associations with metabolites in pig intestines. In comparison with the control (CON) and OH diets, the consumption of FM increased (P PERMANOVA analyses showed distinct (P < 0.05) microbial communities in ileal digesta and mucosa, and caecal mucosa in CON and FM-diets fed pigs compared to the OH diet-fed pigs. The predicted functional metagenomes indicated that amino acids and butanoate metabolism, lysine degradation, bile acids biosynthesis, and apoptosis were selectively enhanced at more than 2.2 log-folds in intestinal microbiota of pigs fed the FM diet. Taken together, flaxseed meal and oat hulls supplementation in growing pigs' diets altered the gastrointestinal development, as well as the composition and function of microbial communities, depending on the intestinal segment and physicochemical property of the dietary fibre source.

    2016-01-01

    Aquaculture is the most rapidly growing segment of global animal production that now surpasses wild-capture fisheries production and is continuing to grow 10% annually. Sustainable aquaculture needs to diminish, and progressively eliminate, its dependence on fishmeal-sourced feed from over-harvested fisheries. Sustainable aquafeed sources will need to be primarily of plant-origin. Soybean is currently the primary global vegetable-origin protein source for aquaculture. Direct exchange of soybean meal for fishmeal in aquafeed has resulted in reduced growth rates due in part to soybean's anti-nutritional proteins. To produce soybeans for use in aquaculture feeds a new conventional line has been bred termed Triple Null by stacking null alleles for the feed-relevant proteins Kunitz Trypsin Inhibitor, lectin, and P34 allergen. Triple Null is now being further enhanced as a platform to build additional transgene traits for vaccines, altered protein composition, and to produce high levels of β-carotene an intrinsic orange-colored aquafeed marker to distinguish the seeds from commodity beans and as the metabolic feedstock precursor of highly valued astaxanthin.

The maximum protease activity was 3028 U/mL using 1.5% (w/v of soybean meal as substrate. Soybean meal is an inexpensive and readily available, thus it can be used as the cost effective crude material for the production of an extracellular protease. Inorganic nitrogen sources proved to be less favorable, for protease production as strong catabolic repression was observed with ammonium ions. A maximum of 3208 U/mL of protease was produced in 18 h in a 10L bioreactor. The enzyme has temperature and pH optima of 60°C and 9.5 respectively. However, the temperature stability range is from 20-90 °C and pH stability range is from 6.0–12.0. The protease was completely inhibited by phenylmethylsulfonyl fluoride (PMSF and diodopropyl fluorophosphate (DFP, with little increase (10-15% in the production of upon addition of Ca++ and Mg++.

    We investigated the effect of the replacement of dietary fish oil with vegetable oils on the growth and flesh quality of large yellow croaker ( Larmichthys crocea). The basal diet (FO) was formulated to contain 66.5% fish meal and 6.4% menhaden fish oil; whereas the other 3 experimental diets were formulated by replacing the fish oil with 50% soybean oil (SO50), 100% soybean oil (SO100) and 100% palm oil (PO100), respectively. The 4 diets were randomly assigned to 4 floating sea cages (3.0 m × 3.0 m × 3.0 m), and each was stocked with 250 fish individuals with an initial average weight of 245.29 g ± 7.45 g. The fish were fed to apparent satiation twice a day at 5:00 and 17:00, respectively, for 12 weeks. Experimental analysis showed that the specific growth rate of fish fed SO50 or PO100 were significantly higher than that of fish fed FO or SO100 ( P0.05). Compared to FO diet, SO50, SO100 and PO100 diets led to substantial decreases in the liquid loss and water loss from fresh fillets (1 d, 4°C) ( Preplacement of fish oil with vegetable oils. These findings indicated that the growth performance and selected flesh quality properties (liquid holding capacity and TBARS value) of large yellow croaker were substantially improved by replacing dietary fish oil with vegetable oils.

In Phase 1, subjects consumed their normal diet on either 6 occasions per day (regular) or by following a variable meal frequency (3-9 meals/day, irregular). In Phase 2, subjects followed the alternative meal pattern to that followed in Phase 1, after a 2-week (wash-out) period. Subjects were asked to come to the laboratory after an overnight fast at the start and end of each phase. Blood samples were taken for measurement of circulating glucose, lipids, insulin and uric acid concentrations before and for 3 h after consumption of a high-carbohydrate test meal. Fasting glucose and insulin values were not affected by meal frequency, but peak insulin and AUC of insulin responses to the test meal were higher after the irregular compared to the regular eating patterns (P meal frequency was associated with higher fasting total (P meal frequency appears to produce a degree of insulin resistance and higher fasting lipid profiles, which may indicate a deleterious effect on these cardiovascular risk factors. : The Ministry of Health and Medical Education, IR Iran.

    Principal component analysis (PCA) is a widely used exploratory method in epidemiology to derive dietary patterns from habitual diet. Such dietary patterns seem to originate from intakes on multiple days and eating occasions. Therefore, analyzing food intake of study populations with different levels of food consumption can provide additional insights as to how habitual dietary patterns are formed. We analyzed the food intake data of German adults in terms of the relations among food groups from three 24-h dietary recalls (24hDRs) on the habitual, single-day, and main-meal levels, and investigated the contribution of each level to the formation of PCA-derived habitual dietary patterns. Three 24hDRs were collected in 2010-2012 from 816 adults for an European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam subcohort study. We identified PCA-derived habitual dietary patterns and compared cross-sectional food consumption data in terms of correlation (Spearman), consistency (intraclass correlation coefficient), and frequency of consumption across all days and main meals. Contribution to the formation of the dietary patterns was obtained through Spearman correlation of the dietary pattern scores. Among the meals, breakfast appeared to be the most consistent eating occasion within individuals. Dinner showed the strongest correlations with "Prudent" (Spearman correlation = 0.60), "Western" (Spearman correlation = 0.59), and "Traditional" (Spearman correlation = 0.60) dietary patterns identified on the habitual level, and lunch showed the strongest correlations with the "Cereals and legumes" (Spearman correlation = 0.60) habitual dietary pattern. Higher meal consistency was related to lower contributions to the formation of PCA-derived habitual dietary patterns. Absolute amounts of food consumption did not strongly conform to the habitual dietary patterns by meals, suggesting that these patterns are formed by complex combinations of variable food

    The objective of the study is to evaluate the nutritional quality of meals consumed away from home and its association with overall diet quality. Data was obtained from 834 participants of a Health Survey in São Paulo, Brazil. Food intake was measured by a 24-hour dietary recall applied telephonically using the Automated Multiple-Pass Method. Overall dietary quality was assessed by the Brazilian Healthy Eating Index Revised (B-HEIR) and the Meal Quality Index (MQI) was used to evaluate dietary quality of the main meals. The association between the B-HEIR and the MQI was assessed by linear regression analysis. The consumption of at least one of the three main meals away from home was reported for 32% of respondents (70 adolescents, 156 adults and 40 elderly). The average MQI score of lunch consumed away from home was lower than lunch consumed at home, with higher amounts of total and saturated fats. The average score of B-HEIR was 58 points and was associated with the MQI score, energy, meal consumption location and gender.

    Mannan oligosaccharides, as an alternative to an-tibiotics, show promising results related to bird perfor-mance, immunity stimulus and improvement of intestinal mucosa. Enzyme inclusion in diets containing mannan oli-gosaccharides could improve these results. Poultry diets consist of corn and soybean meal, and approximately 30% of the phosphorus (P in these ingredients is bound to phytic acid. Phytase is capable of release not only the P but also other nutrients that can be better used by the birds while corn is relatively free of viscosous nonstarch poly-saccharides (NSP, soybean has about 20% of NSP, whose digestibility is almost null. NSP`s insoluble component of corn and soybean encapsulate nutrients and are responsive to exogenous enzymes. Negative environmental and nutri-tional consequences of dietary phytic acid are reduced by phytase inclusion in monogastric diets. Additionally, the enzymatic complex supplementation improves the nutri-tional value of feedstuffs through higher digestibility in birds. Finally, the use of exogenous enzymes allows re-duction in feed costs.

    Strawberries are a dietary source of anthocyanins, particularly pelargonidin glycosides. Dietary anthocyanins have received increasing attention among researchers and consumers due to their health benefits. The oral bioavailability of anthocyanins is reported to be low and various dietary factors may influence their oral bioavailability further. Milk is suggested to reduce (poly)phenols' oral bioavailability. However, the effect of milk on anthocyanin oral bioavailability remains uncertain. Likewise, mixed nutrient meals may influence the oral bioavailability of anthocyanins. Therefore, the purpose of this study was to assess the effect of milk on the oral bioavailability and other pharmacokinetic (PK) variables of strawberry anthocyanins consumed with and without a meal. Nine healthy participants consumed a strawberry beverage prepared in milk or water with a standard meal on two occasions. On two additional occasions, the beverages were given to a subset (n = 4) of participants to determine the impact of the meal on anthocyanin PK variables, including oral bioavailability. Independent of the meal, beverages prepared in milk significantly reduced the peak plasma concentrations (C max ) of pelargonidin-3-O-glucoside (P-3-G), pelargonidin-glucuronide (PG) and pelargonidin-3-O-rutinoside (P-3-R), as well as the PG and P-3-R area under the curve (AUC) (p bioavailability of pelargonidin anthocyanins under meal conditions; however, the oral relative bioavailability of pelargonidin anthocyanins was reduced by ∼50% by milk under without meal conditions (p < 0.05). Consuming strawberry beverages made with milk and consuming those made with water with and without a meal influenced different aspects of strawberry anthocyanin PKs. The significance of this effect on clinical efficacy requires additional research.

    Patients with obesity, including morbid obesity, commit numerous dietary mistakes. They prefer high-energy diets, but of poor nutritional value. Patients qualified for bariatric procedures show deficiencies in vitamins and minerals due to insufficient intake of vegetables, fruit and whole grain products. Analysis of dietary habits in morbidly obese patients prepared for bariatric surgery, including assessment of eating style and frequency of consumption of certain products. The study group contained 39 people aged 18 - 65 years, who were surveyed with a questionnaire elaborated in the Department of Clinical Dietetics and Nutrition, Medical University of Bialystok. The following factors were assessed: number of meals, snacking between meals and eating at night, types of snacks eaten, and frequency of consumption of certain foods. Results were analyzed using Statistica 9.0. The majority of surveyed men (41.7%) ate three meals a day, whereas most women (40.7%) had at least 4 meals a day. Nearly 85% of the respondents admitted snacking between meals, mainly eating fruit, sweets and sandwiches. Whole grain cereal, milk and dairy products, fish, fruit, vegetables and pulses appeared in diet of patients qualified for treatment of obesity very rarely. Dietary habits of obese patients qualified for bariatric procedures are not consistent with recommendations. Therefore, these patients should receive nutritional education in order to foster proper eating habits that will help in the postoperative nutrition.

    A feeding trial was conducted to evaluate the effects of replacing fish meal with rubber seed meal (RSM) on growth, nutrient utilization, and cholesterol metabolism of tilapia (Oreochromis niloticus × Oreochromis aureus). Five experimental diets were formulated with 0, 150, 300, 450, and 600 g kg -1 RSM replacing graded levels of fish meal, respectively. Each diet was randomly assigned to triplicate groups of 25 fish (initial average weight 65.3 g) per aquarium in a rearing system maintained at 29 ± 1 °C for 8 weeks. Dietary 150 g kg -1 RSM inclusion did not affect the weight gain and daily growth coefficient, whereas these were depressed by a further inclusion. Additionally, feed efficiency ratio and protein efficiency ratio were not affected by dietary RSM inclusion regardless of inclusion level. However, the inclusion of 450 and 600 g kg -1 RSM decreased the mid-intestinal trypsin, lipase, and amylase activities; the hepatic acyl-CoA/cholesterol acyl transferase; low-density lipoprotein receptor; and 3-hydroxy-3-methyl-glutaryl-CoA reductase activities. Similarly, dietary 600 g kg -1 RSM inclusion inhibited the plasma catalase and hepatic glutathione peroxidase activities. These results indicated that 150 g kg -1 RSM can be included in tilapia diets, whereas higher inclusion of RSM inhibited the growth rate, digestive enzyme activity, antioxidant capacity, and cholesterol metabolism.

    Our aim was to examine the control of gastric emptying of the oil phase of a mixed solid and liquid meal. Previous studies had shown that liquid dietary fats normally leave the stomach at a slower rate than does water. We wished to determine whether the slower emptying of fats was due to the physical characteristics of food (lower density and greater viscosity than water), to retardation by duodenal feedback mechanisms, or whether both factors contributed. Thus, we quantified the emptying rates of water and sucrose polyester (a nonabsorbable analog of dietary fat) ingested by healthy volunteers as a mixed solid and liquid meal. Gastric emptying was quantified by an intubation-perfusion method incorporating an occlusive jejunal balloon to facilitate recovery. Four phase-specific, nonabsorbable markers were used. [14C[Sucrose octaoleate and polyethylene glycol were incorporated in the meal and traced the lipid and water phases, respectively; [3H]glycerol triether and phenolsulfonphthalein were used as duodenal recovery markers. Sucrose polyester (substituting for dietary fat) was emptied very rapidly, and at about the same rate as was water, in contrast to natural fat, which empties very slowly. Emptying of water was rapid and comparable to that observed after mixed meals containing natural fat. These results imply that gastric emptying of the oil phase is controlled by receptors sensitive to the hydrolytic products of fat digestion and that the slow emptying of dietary fat is not simply due to its lower density

    This experiment was conducted to evaluate the effects of different levels of Hatchery Wastes (HW) on performance, tibia ash, blood calcium and phosphorus concentrations in broiler chickens. Birds were fed a corn-soybean meal diet for 7 days. The experimental treatments included a corn soybean meal diet and 3 other treatments containing 1.5, 3.0 and 4.5% HW. five replicate groups of 15 Ross 308 broiler chicks were allocated to each dietary treatment. Data were analyzed in a completely randomized design. Results indicated that there were no significant differences in weight gains among different dietary treatments. Feed intake in the 4.5% treatment was significantly higher (p 0.05). Results of carcass analysis showed no significant differences between treatments. Also, there were no significant differences between blood calcium and phosphorous among treatments. The 4.5 and 3.0% hatchery wastes treatments had the highest tibia ash (p hatchery wastes as much as 3% can increase tibia strength without having adverse effect on broilers performance.

    To describe shared meal patterns and examine associations with dietary intake among young adults. Population-based, longitudinal cohort study (Project EAT: Eating and Activity in Teens and Young Adults). Participants completed surveys and FFQ in high-school classrooms in Minneapolis/St. Paul, MN, USA in 1998-1999 (mean age = 15·0 years, 'adolescence') and follow-up measures online or by mail in 2008-2009 (mean age = 25·3 years, 'young adulthood'). There were 2052 participants who responded to the 10-year follow-up survey and reported on frequency of having shared meals. Among young adults, the frequency of shared meals during the past week was as follows: never (9·9 %), one or two times (24·7 %), three to six times (39·1 %) and seven or more times (26·3 %). Having more frequent family meals during adolescence predicted a higher frequency of shared meals in young adulthood above and beyond other relevant sociodemographic factors such as household composition and parental status. Compared with young adults who never had family meals during adolescence, those young adults who reported seven or more family meals per week during adolescence had an average of one additional shared meal per week. Having more frequent shared meals in young adulthood was associated with greater intake of fruit among males and females, and with higher intakes of vegetables, milk products and some key nutrients among females. Nutrition professionals should encourage families of adolescents to share meals often and establish the tradition of eating together, and work with young adults to ensure that healthy food and beverage choices are offered at mealtimes.

    An in vitro method was used to evaluate the degradation of myo-inositol hexakisphosphate (InsP6) in non-heat-treated wheat (NHW), heat-treated wheat (HW), soybean meal (SBM) or rapeseed cake (RSC) soaked separately or in combination. The feedstuffs were soaked in water (20 °C) and samples were...... heat-treatment and soaking time (P≤0.001). This was mainly due to a smaller proportion of non-degraded InsP6-P at 24 h in HW compared with NHW (0.13 vs. 0.47) (P≤0.001) possibly caused by structural changes imposed by the heat-treatment. In SBM, RSC, SBM/NHW or RSC/NHW, the InsP6 degradation...... was affected by the interaction between phytase addition and soaking time (P≤0.001) as phytase reduced the proportion of non-degraded InsP6-P at 2, 4, 8 or 24 h. Soaking of NHW, SBM or RSC (without phytase) separately resulted in a limited InsP6 degradation, whereas a pronounced InsP6 degradation occurred when...

    To determine the prevalence and correlates of missing meals among adolescents. The 2010 National Youth Physical Activity and Nutrition Study, a cross-sectional study. School based. A nationally representative sample of 11 429 high school students. Breakfast, lunch, and dinner consumption; demographics; measured and perceived weight status; physical activity and sedentary behaviors; and fruit, vegetable, milk, sugar-sweetened beverage, and fast-food intake. Prevalence estimates for missing breakfast, lunch, or dinner on ≥1 day during the past 7 days were calculated. Associations between demographics and missing meals were tested. Associations of lifestyle and dietary behaviors with missing meals were examined using logistic regression controlling for sex, race/ethnicity, and grade. In 2010, 63.1% of students missed breakfast, 38.2% missed lunch, and 23.3% missed dinner; the prevalence was highest among female and non-Hispanic black students. Being overweight/obese, perceiving oneself to be overweight, and video game/computer use were associated with increased risk of missing meals. Physical activity behaviors were associated with reduced risk of missing meals. Students who missed breakfast were less likely to eat fruits and vegetables and more likely to consume sugar-sweetened beverages and fast food. Breakfast was the most frequently missed meal, and missing breakfast was associated with the greatest number of less healthy dietary practices. Intervention and education efforts might prioritize breakfast consumption.

    Full Text Available Objective: This study aimed to characterize away-from-home meals. Methods: This population-based, cross-sectional study measured dietary intake by administering 24-hour recalls by telephone. Away-from-home breakfast, lunch, and dinner were described and characterized according to the foods that contribute most to the intake of energy, fat, sodium, and added sugar per meal. Results: f the 834 respondents, 24% had had at least one meal away from home. The average energy intake per away-from-home meal was 628 kcal (±101 kcal, about 35% of the average daily intake for this population. Meals contained both healthy foods, such as rice, beans, and fish, and unhealthy foods, such as soft drinks, snacks, sandwiches, and pizza. Conclusion: Individuals who ate away from home had worse diets. However, the presence of healthy foods indicates a possibility of improvement if purposeful programmatic actions are taken.

    Male commercial broiler strain chickens were fed from hatching to 42 d of age either a control diet (based on corn and soybean meal) or the control diet supplemented with 250 mg copper/kg diet from cupric sulfate pentahydrate (for 35 or 42 d). Hypocholesterolemia (11.8% reduction) and decreased breast muscle cholesterol (20.4% reduction) were observed in copper-supplemented birds. There was a slight increase (P > .05) in breast muscle copper (14.5%), and all levels were very low (copper for 42 vs 35 d resulted in lower levels of cholesterol in the plasma (12.9 vs 10.8% reduction) and breast muscle (24.6 vs 16.2% reduction). Very similar results were found in two additional experiments in which hypocholesterolemia and reduced breast muscle cholesterol were associated with reduced plasma triglycerides and blood reduced glutathione. It is well known that hypercholesterolemia is a symptom of dietary copper deficiency. The data presented here indicate that blood and breast muscle cholesterol are inversely related to dietary copper in excess of the dietary requirement for maximal growth. The cholesterol content of the edible muscle tissue of broiler chickens can be reduced by approximately 25% after feeding a supranormal level of copper for 42 d without altering the growth of the chickens or substantially increasing the copper content of the edible meat.

    Sixty-four gilts were assigned to be bred at first or third observed estrus and fed gestation diets of pelleted wheat shorts with a free choice mineral-vitamin supplement or fortified corn-soybean meal. Only the dietary effects are included in this report. The gilts were fed their respective diets starting at 25 days after insemination. The experiment continued through three gestation-lactation cycles. Females fed the wheat shorts received less digestible energy during gestation and weighed less at day 109 of gestation and days 1, 7 and 21 of lactation in each of the three gestation-lactation periods. Females fed wheat shorts had lighter pigs at birth, weaned more pigs per litter in each parity and returned to estrus more slowly after weaning than females fed a corn-soybean meal diet. Results of a metabolism trial conducted with 12 barrows revealed that wheat shorts contained approximately 2.93 kcal digestible energy/kg dry matter and had an apparent protein digestibility of 72%, compared with values of 4.0 kcal and 86%, respectively, for the corn-soybean meal diets.

    The aim of this study was to examine differences in the validity of a visual estimation method for determining patients' meal intake between various meal types and supplied food items in hospitals and to find factors influencing the validity of a visual estimation method. There are two procedures by which we obtained the information on dietary intake of the patients in these hospitals. These are both by visual assessment from the meal trays at the time of their clearing, by the attending nursing staff and by weighing conducted by researchers. The following criteria are set for the target trays: A) standard or therapeutic meals, which are monitored by a doctor, for energy and/or protein and/or sodium; B) regular, bite-sized, minced and pureed meal texture, and C) half-portion meals. Visual assessment results were tested for their validity by comparing with the corresponding results of weighing. Differences between these two methods indicated the estimated and absolute values of nutrient intake. A total of 255 (76.1%) trays were included in the analysis out of the 335 possible trays and the results indicated that the energy consumption estimates by visual or weighing procedures are not significantly different (412 ± 173 kcal, p = 0.15). However, the mean protein consumption was significantly different (16.3 ± 6.7 g/tray, p food items were significantly misestimated for energy intake (66 ± 58 kcal/tray) compared to trays with no additions (32 ± 39 kcal/tray, p food items were significantly associated with increased odds of a difference between the two methods (OR: 3.84; 95% confidence interval [CI]: 1.07-13.85). There were high correlations between the visual estimation method and the weighing method measuring patients' dietary intake for various meal types and textures, except for meals with added supplied food items.

    Recent studies suggest that supplemental Ca (SC) increases the risk of cardiovascular events, whereas dietary Ca (DC) decreases the risk of cardiovascular events. Although frequently consumed with meals, it remains unclear whether Ca can mitigate or aggravate the deleterious effects of a high-fat meal on cardiovascular risk factors. This study aimed to evaluate the effects of SC or DC on blood pressure (BP) and microvascular function (MVF) in the postprandial period in obese women challenged with a high-fat meal. In this cross-over controlled trial, sixteen obese women aged 20-50 years were randomly assigned to receive three test meals (2908 kJ (695 kcal); 48 % fat): high DC (HDCM; 547 mg DC), high SC (HSCM; 500 mg SC-calcium carbonate) and low Ca (LCM; 42 mg DC). BP was continuously evaluated from 15 min before to 120 min after meals by digital photoplethysmography. Before and 120 min after meals, participants underwent evaluation of serum Ca and microvascular flow after postocclusive reactive hyperaemia (PORH) by laser speckle contrast imaging. Ionised serum Ca rose significantly only after HSCM. Systolic BP increased after the three meals, whereas diastolic BP increased after LCM and HDCM. Hyperaemia peak, hyperaemia amplitude and AUC evaluated after PORH decreased with LCM. After HDCM, there was a reduction in hyperaemia peak and hyperaemia amplitude, whereas HSCM decreased only hyperaemia peak. However, comparative analyses of the effects of three test meals on serum Ca, BP and MVF revealed no significant meal×time interaction. This study suggests that in obese women SC and DC do not interfere with the effects of a high-fat meal on BP and MVF.

    Full Text Available This study was carried out in order to assess commercial front and rear cuts of dairy-origin cattle fed mesquite pod meal. Twenty-five non-castrated male bovines (Holstein-Zebu, distributed according to a completely randomized design, with five animals per treatment, were used. The feed contained about 121.2 and 544.98 g kg-1 of crude protein and total digestible nutrients, respectively, and was composed of tifton grass hay, cornmeal, soybean meal, mesquite pod meal and mineral salt. The right half carcass of each animal was separated between the 5th and 6th ribs, in front and rear quarters, from which commercial cuts were obtained. There was no effect (p > 0.05 as to the replacement of corn for mesquite pod meal on the weights and yields of front cuts (shoulder, brisket, chuck, hump and flanks and rear cuts (tenderloin, shank, knuckle, thin flank, flat, eye round, rump tail, top side, cap of rump, rump, cut of rump, striploin, cap of cube roll. Mesquite pod meal can substitute cornmeal in 100% in the concentrate without changes in weight and yield of the commercial front and rear cuts of male bovines of dairy origin.

    Rumen degradabilities were determined for various proteins by incubation for 48 h in nylon bags. Values obtained were 37.3% for corn grain and feather meal, 59.6% for alfalfa meal, 63.4% for cottonseed meal, 66.8% for soybean meal and 68.0% for rice polishings. Fish meal protein degradability was less than 45%. Sheep given either cottonseed meal or fish meal as sources of 'bypass' protein did not show differences in daily gain or intake. Fish meal diets gave better feed/gain ratios. Fish meal or urea supplementation of a basal diet containing 4.6% crude protein increased feed intake, daily gain, the feed/gain ratio and wool staple length. Castrated sheep grazing native pastures of the Peruvian Andes (altitude approximately 3800 m) during either the rainy or dry season did not show significant improvement in growth rate with fish meal supplementation. Supplementation of ewes at first mating produced higher weights at the end of gestation, as well as an increase in the number and weight of lambs born, in the weaning rate and in wool weight from the ewes.

    We have previously shown that the postprandial experience includes cognitive sensations, such as satiety and fullness, with a hedonic dimension involving digestive well-being and mood. Preload conditioning has been shown to modulate appetite and food consumption under certain conditions, but its effects on the responses to meal ingestion are not clear. We hypothesized that appetite modulation by preload conditioning has differential effects on the cognitive and the emotive responses to meal ingestion. The effects of preload conditioning (ingestion of a low- vs a high-calorie breakfast) on appetite and on the cognitive and emotive responses to a comfort probe meal ingested 2 hours later (ham and cheese sandwich with orange juice; 300 mL, 425 Kcal) was tested in healthy subjects (n=12) in a cross-over design. Sensations were measured at regular intervals 15 minutes before and 60 minutes after the probe meal. As compared to the low-calorie breakfast, the high-calorie breakfast reduced basal hunger sensation and influenced the responses to the subsequent probe meal: it increased satiety (4.3±0.2 score vs 2.7±0.2 score; PAppetite modulation by preload conditioning has differential effects on the cognitive and emotive responses to a meal. Preload conditioning of the postprandial experience may be applicable to dietary planning and prevention of postprandial symptoms. © 2017 John Wiley & Sons Ltd.

    Employed parents’ work and family conditions provide behavioral contexts for their food choices. Relationships between employed parents’ food-choice coping strategies, behavioral contexts, and dietary quality were evaluated. Data on work and family conditions, sociodemographic characteristics, eating behavior, and dietary intake from two 24-hour dietary recalls were collected in a random sample cross-sectional pilot telephone survey in the fall of 2006. Black, white, and Latino employed mothers (n=25) and fathers (n=25) were recruited from a low/moderate income urban area in upstate New York. Hierarchical cluster analysis (Ward’s method) identified three clusters of parents differing in use of food-choice coping strategies (ie, Individualized Eating, Missing Meals, and Home Cooking). Cluster sociodemographic, work, and family characteristics were compared using χ2 and Fisher’s exact tests. Cluster differences in dietary quality (Healthy Eating Index 2005) were analyzed using analysis of variance. Clusters differed significantly (P≤0.05) on food-choice coping strategies, dietary quality, and behavioral contexts (ie, work schedule, marital status, partner’s employment, and number of children). Individualized Eating and Missing Meals clusters were characterized by nonstandard work hours, having a working partner, single parenthood and with family meals away from home, grabbing quick food instead of a meal, using convenience entrées at home, and missing meals or individualized eating. The Home Cooking cluster included considerably more married fathers with nonemployed spouses and more home-cooked family meals. Food-choice coping strategies affecting dietary quality reflect parents’ work and family conditions. Nutritional guidance and family policy needs to consider these important behavioral contexts for family nutrition and health. PMID:21338739

    Full Text Available In this experiment, 240 Cobb-500® broilers reared from1 to 49 days, and distributed according to a completely experimental randomized design with four treatments of four replicates each in order to evaluate the effect of the dietary inclusion of 0, 33, 66 or 100 g/kg of squash seed meal (SSM (Cucurbita moschata on the performance, carcass yield, serum lipid profile and sensory meat quality of broilers. Significant differences (p<0.05 were detected in performance, carcass weight, weight and breast yield, and leg weight. The best results were obtained with 33 and 66 g/kg as compared to the control diet and 100 g SSM /kg. Abdominal fat decreased with the inclusion of 66 and 100 g SSM / kg, but the sensory quality of breast and thighs was not affected by the inclusion of SSM. The serum levels of total cholesterol, very low density (VLDL and low density (LDL lipoproteins, triglycerides, glucose and atherogenic index decreased with the inclusion of 100 g/kg of SSM, except for high density lipoproteins (HDL, which increased. The inclusion of 0, 33, 66 and 100 g/kg of SSM in broiler diets, partially replacing soybean meal and vegetable oil, improved live performance and edible portions yield. In addition, abdominal fat and serum levels of harmful lipids were reduced, whereas serum levels of beneficial lipids increased. There was no effect on meat sensory quality.

  16. Digestibility and pricing of Chlorella sorokiniana meal for use in tilapia feeds

    Directory of Open Access Journals (Sweden)

    Rafael Simões Coelho Barone

    Full Text Available ABSTRACT: Several microalgae contain in excess of 50 % crude protein with amino acid profile comparable to that of fish meal. In addition, high polyunsaturated fatty acid contents encourage their use in animal feeding and nutrition, particularly in the formulation and processing of aquafeeds. This study aims at estimating the feasibility of Chlorella meal as feed ingredient for the feeding and nutrition of farmed tilapia based upon digestibility data. Juvenile tilapia were stocked in conical-bottomed tanks (200 L with superficial, continuous water flow, and fed to apparent satiation in three daily meals with a reference diet and a test diet containing 30 % lyophilized Chlorella sorokiniana added of an inert marker. Feces were collected overnight by sedimentation in refrigerated, plastic containers coupled to the tanks and analyzed for determination of chemical composition and inert marker contents to estimate apparent digestibility coefficients (ADCs of protein and energy of Chlorella meal; registered ADCs of Chlorella meal were 90.5 and 84.22, respectively. A pricing model considering the quantity of digestible nutrient was proposed based on ADCs of Chlorella and compared with the price of fishmeal (FM and soybean meal (SBM. The indicative prices to elicit the use of Chlorella as a protein source rather than FM or SBM for the feed and nutrition of tilapia were 2.65 USD kg−1 and 0.66 USD kg−1, respectively.

    Full Text Available An experiment was conducted to evaluate the effect of replacing fish meal with grasshopper meal on haematology, blood chemistry and carcass characteristics of growing rabbits. Forty rabbits of mixed breeds, aged 6-10 weeks, were randomly assigned to the dietary treatments in a complete randomized design with eight rabbits per treatment. The rabbits were fed with diets containing 0, 1.25, 2.50, 3.75 and 5% grasshopper meal in diets designated as T1 (control, T2, T3, T4 and T5, respectively. The experimental diets and clean drinking water were supplied ad libitum throughout the experimental period of nine weeks. At the end of the feeding trial, three rabbits per treatment were slaughtered for carcass evaluation, while blood samples were collected for analysis. The result of the experiment showed significant differences (P0.05 on haemoglobin and mean corpuscular haemoglobin concentration (MCHC. The results also revealed significant differences (P0.05 on serum albumin and total protein. The results of carcass characteristics showed significant differences among treatments (P<0.05 for slaughter weight, carcass weight, dressing percentage, skin pelt, tail, feet and abdominal fat. The slaughter weight and carcass weight were better in groups receiving 2.5% grass hopper meal (50% fish meal replacement. From the results, it can be concluded that inclusion of 2.50% grasshopper meal as a replacement for fish meal (50% replacement has no adverse effects on the haematological parameters, serum biochemistry and carcass characteristics of rabbits.

    Objective The objective of this experiment was to determine apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of crude protein (CP) and amino acid (AA) in 15 sources of soybean meal (SBM) produced from soybeans from different countries and subsequently to establish equations for predicting the AID and SID in SBM based on their chemical composition. Methods Eighteen barrows (57.9±6.1 kg) fitted with a simple T-cannula were allotted into three 6×6 Latin square designs. Each period comprised a 6-d adaption period followed by a 2-d collection of ileal digesta. The 15 test diets included SBM as a sole source of AA in the diet. Another nitrogen-free diet was used to measure basal endogenous losses of CP and AA. Chromic oxide (0.3%) was used as an inert marker in each diet. Results The AID of lysine in SBM from China and USA tended to be greater than in SBM from Brazil (p<0.10). The SID of valine and proline in SBM from China was greater than in SBM from Brazil (p<0.05). The SID of lysine, threonine, cysteine and glycine in SBM from China tended to be greater than in SBM from Brazil (p<0.10). From a stepwise regression analysis, a series of AID and SID prediction equations were generated. The best fit equations for lysine in SBM were: AID lysine = 1.16 sucrose−1.81 raffinose+82.10 (R2 = 0.69, p<0.01) and SID lysine = 1.14 sucrose−1.93 raffinose−0.99 ether extract (EE)+85.26 (R2 = 0.77, p<0.01). Conclusion It was concluded that under the conditions of this experiment, the oligosaccharides (such as sucrose and raffinose) can be used to predict the AID and SID of AA in SBM with reasonable accuracy.

    This study was carried out to compare the physicochemical and sensory properties of chicken thigh muscles from broilers fed different levels of garlic bulb (GB) and garlic husk (GH). Two hundred male Arbor Acre broiler chickens were fed either a control diet (based on corn and soybean meal) or the control diet supplemented with 2 and 4% of GB and GH powder for 5 wk. There were no differences among diets in moisture and ash contents. However, dietary supplementation with GB and GH resulted in significantly greater protein content and lower fat content in chicken thigh muscle compared with muscle from birds fed nonsupplemented diets (Pchicken diets with garlic can produce chicken meat with favorable lipid profiles and can enhance eating quality because sensory panels found that thigh meat from chickens fed a garlic-supplemented diet had better texture and flavor. Therefore, the treatment with the most significant effects in this study was that with the high level of garlic husk.

    Chickens can hepatically synthesize eicosapentaenoic acid (20:5 n-3) and docosahexaenoic acid (22:6 n-3) from α-linolenic acid (ALA; 18:3 n-3); however, the process is inefficient and competitively inhibited by dietary linoleic acid (LNA; 18:2 n-6). In the present study, the influence of dietary high-oleic acid (OLA; 18:1 n-9) soybean oil (HOSO) on egg and tissue deposition of ALA and n-3 polyunsaturated fatty acids (PUFA) synthesized from dietary ALA was investigated in laying hens fed a reduced-LNA base diet supplemented with high-ALA flaxseed oil (FLAX). We hypothesized that reducing the dietary level of LNA would promote greater hepatic conversion of ALA to very long-chain (VLC; >20C) n-3 PUFA, while supplemental dietary HOSO would simultaneously further enrich eggs with OLA without influencing egg n-3 PUFA contents. Nine 51-week-old hens each were fed 0, 10, 20, or 40 g HOSO/kg diet for 12 weeks. Within each group, supplemental dietary FLAX was increased every 3 weeks from 0 to 10 to 20 to 40 g/kg diet. Compared to controls, dietary FLAX maximally enriched the total n-3 and VLC n-3 PUFA contents in egg yolk by 9.4-fold and 2.2-fold, respectively, while feeding hens 40 g HOSO/kg diet maximally attenuated the yolk deposition of ALA, VLC n-3 PUFA, and total n-3 PUFA by 37, 15, and 32%, respectively. These results suggest that dietary OLA is not neutral with regard to the overall process by which dietary ALA is absorbed, metabolized, and deposited into egg yolk, either intact or in the form of longer-chain/more unsaturated n-3 PUFA derivatives. © 2018 AOCS.

    This study aimed to evaluate the effect of micronized pea seeds introduced into feed mixes for broilers on the slaughter yield, blood lipid parameters, content of fatty acids in selected tissues, and meat quality. The studies involved 150 1-day-old Ross 308 chicks split into three groups (for 42 days). The feed rations differed in terms of the source of proteins: in the control group (C), it was post-extraction soybean meal (SBM) 100%; in group I, SBM 50% and micronized peas 50%; and in group II, micronized peas only, 100%. Irradiated pea seeds added to the feed ration for chicks reduced the fattening grade of carcasses (P seeds in feed mixes decreased the share of saturated fatty acids in the muscles and abdominal fat and had a positive effect on the n-6/n-3 ratio, hypocholesterolemic / hypercholesterolemic ratio, as well as the atherogenic and thrombogenic indices (P < 0.05). © 2016 Japanese Society of Animal Science.

    1. The apparent ileal nitrogen (N) and amino acid digestibilities in chaya leaf meal (CLM) (Cnidoscolus aconitifolius) with added enzymes, and the same variables in diets containing different amounts of CLM were studied in chickens. 2. In the first experiment pectinase, beta-glucanase, and pectinase + beta-glucanase were added to CLM. In the second experiment, there were three diets based on maize and soybean: 0, 150 and 250 g/kg CLM. 3. Pectinase significantly increased both lysine and overall amino acid digestibilities in CLM. 4. In experiment 2, the amino acid digestibility in birds fed on CLM250 was lower than that from birds fed on either control or CLM150. Only the digestibilities of alanine, arginine and proline were lower in birds fed on CLM150 than in those fed on the control diet. Nitrogen digestibility was lower in birds fed on the CLM250 diet than on either control or CLM150 diets. These findings were attributed to the increasing concentration of fibre with increasing dietary CLM.

    Full Text Available Maintenance of proper health and prevention of diseases of civilization are now significant public health problems. Nutrition is an important factor in the development of youth, as well as the current and future state of health. The aim of the study was to show the benefits of the application of cluster analysis to assess the dietary habits of high school students. The survey was carried out on 1,631 eighteen-year-old students in seven randomly selected secondary schools in Bialystok using a self-prepared anonymous questionnaire. An evaluation of the time of day meals were eaten and the number of meals consumed was made for the surveyed students. The cluster analysis allowed distinguishing characteristic structures of dietary habits in the observed population. Four clusters were identified, which were characterized by relative internal homogeneity and substantial variation in terms of the number of meals during the day and the time of their consumption. The most important characteristics of cluster 1 were cumulated food ration in 2 or 3 meals and long intervals between meals. Cluster 2 was characterized by eating the recommended number of 4 or 5 meals a day. In the 3rd cluster, students ate 3 meals a day with large intervals between them, and in the 4th they had four meals a day while maintaining proper intervals between them. In all clusters dietary mistakes occurred, but most of them were related to clusters 1 and 3. Cluster analysis allowed for the identification of major flaws in nutrition, which may include irregular eating and skipping meals, and indicated possible connections between eating patterns and disturbances of body weight in the examined population.

    Since the beginning of 1970, there has been a great breakthrough in the popularization of soy-bean-based food in Nigeria and in many parts of the developing world, especially for use in the prevention of kwashiorkor. Since 1975, soy bean has become a main source of daily dietary protein in many parts of Nigeria as a result of the successful incorporation of soy-bean products into almost all traditional Nigerian foods. This is a review of previous work in Nigeria on eliminating the beany flavour, bitter taste, and flatus factors in soy-bean milk and cooked soy-bean paste preparations.

    Responses to stocking density (SD), dietary biotin concentration and litter condition were evaluated on 2016 Ross 308 male broilers in the fattening period (day 22-day 42). The birds were placed in 48 pens with either dry or wet litter to simulate the final stocking density of 30 kg (12 broilers/m 2 ; normal stocking density, NSD) and 40 kg (16 broilers/m 2 ; high stocking density, HSD) of body weight (BW)/m 2 floor space. A corn-soybean meal-based diet was supplemented with biotin to provide a normal (NB; 155 μg/kg) or high (HB, 1521 μg/kg) level of dietary biotin. There were six repetitions per treatment. The inappropriate moisture content of litter associated with HSD was avoided (p  0.05) for growth and processing yield. In HSD, the biotin effect (gains, FCR) was significantly higher (p chickens, and a significant interaction (p density, biotin supplementation and litter condition existed from 35 to 42 days of age.

In this study, we evaluated the effects of consuming yellow soybeans, black soybeans (Glycine max), or sword beans (Canavalia gladiate) on lipid and oxidative stress levels in an ovariectomized rat model. Forty-seven nine-week-old female rats were ovariectomized, randomly divided into four groups, and fed one of the following diets for 10 weeks: a diet supplemented with casein (NC, n = 12), a diet supplemented with yellow soybean (YS, n = 12), a diet supplemented with black soybean (BS, n = 12), or a diet supplemented with sword bean (SB, n = 11). Plasma triglyceride (TG) levels in the BS and SB groups were significantly lower than that in the NC group. Notably, the BS group had significantly lower plasma total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels than the other groups. Hepatic total lipid levels were significantly lower in the YS and SB groups, and cholesterol levels were significantly lower in the SB group than in the NC group. Superoxide dismutase (SOD) and catalase (CAT) activities were significantly higher in the groups fed beans compared to the NC group. Hepatic thiobarbituric acid reactive substances (TBARS) levels were also significantly lower in the BS and SB groups than the NC group. In conclusion, our results suggest that consumption of various types of beans may inhibit oxidative stress in postmenopausal women by increasing antioxidant activity and improving lipid profiles. Notably, intake of black soybean resulted in the greatest improvement in risk factors associated with cardiovascular disease.

    Findings from few studies that investigated the relation between dietary behaviors and obesity are inconsistent. We aimed to assess the relation between patterns of dietary habits, identified by latent class analysis (LCA), and obesity in a large sample of Iranian adults. In a cross-sectional study on 7958 adults, dietary behaviors were assessed in five domains (meal patterns, eating rate, intra-meal fluid intake, meal-to-sleep interval, and fatty foods intake) using a pretested questionnaire. LCA was applied to identify classes of diet-related practices. Anthropometric measures were assessed through the use of a validated self-reported questionnaire. General and abdominal obesity were defined as a body mass index ≥ 30 kg/m(2), and a waist circumference ≥ 88 cm for women and ≥ 102 cm for men. General and abdominal obesity were prevalent in 9.7 and 27.7 % of the study population, respectively. We identified three distinct classes of eating rates (moderate, moderate to slow, and moderate to fast), two classes of meal patterns (regular and irregular), two classes of intra-meal fluid intake (moderate and more intra-meal drinking), three classes of meal-to-sleep interval (short, moderate, and long meal-to-sleep interval), and three classes of fatty food intake (low to moderate, moderate to high, and low intake of fatty foods). After adjustment for potential confounders, individuals with 'irregular meal pattern' were 21, 24, and 22 % more likely to be overweight/obese, abdominally overweight/obese, and abdominally obese, compared with those who had a 'regular meal pattern.' Individuals with 'more intra-meal drinking' had greater odds of overweight (OR 1.37; 1.19-1.458) and obesity (OR 1.51; 1.16-1.97) than those with 'moderate intra-meal drinking.' Moderate-to-high intake of fatty foods was inversely associated with abdominally overweight/obese (OR 0.85; 0.73-1.00) and abdominally obesity (OR 0.80; 0.68-0.96) compared with 'low-to-moderate intake of fatty foods

    Full Text Available In Atlantic salmon (Salmo salar L., and also in other fish species, certain plant protein ingredients can increase fecal water content creating a diarrhea-like condition which may impair gut function and reduce fish growth. The present study aimed to strengthen understanding of the underlying mechanisms by observing effects of various alternative plant protein sources when replacing fish meal on expression of genes encoding proteins playing key roles in regulation of water transport across the mucosa of the distal intestine (DI. A 48-day feeding trial was conducted with five diets: A reference diet (FM in which fish meal (72% was the only protein source; Diet SBMWG with a mix of soybean meal (30% and wheat gluten (22%; Diet SPCPM with a mix of soy protein concentrate (30% and poultry meal (6%; Diet GMWG with guar meal (30% and wheat gluten (14.5%; Diet PM with 58% poultry meal. Compared to fish fed the FM reference diet, fish fed the soybean meal containing diet (SBMWG showed signs of enteritis in the DI, increased fecal water content of DI chyme and higher plasma osmolality. Altered DI expression of a battery of genes encoding aquaporins, ion transporters, tight junction and adherens junction proteins suggested reduced transcellular transport of water as well as a tightening of the junction barrier in fish fed the SBMWG diet, which may explain the observed higher fecal water content and plasma osmolality. DI structure was not altered for fish fed the other experimental diets but alterations in target gene expression and fecal water content were observed, indicating that alterations in water transport components may take place without clear effects on intestinal structure.

    The diversity of thermophilic bacteria was not significantly altered while growing in a defatted soybean meal (DFSM) slurry at 60 °C for 10, 20, and 30 days. Five species of thermophilic bacteria, which belong to the genera Aeribacillus (temperature gradient gel electrophoresis [TGGE] band no. 1), Saccharococcus (TGGE band no. 2), Geobacillus (TGGE band no. 3), Bacillus (TGGE band no. 4), and Anoxybacillus (TGGE band no. 5), were detected in the fermenting DFSM slurry. The cell-free culture fluid obtained from the fermenting DFSM slurry on day 14 hydrolyzed starch and soy protein at 60 °C but not at 30 °C. Soy sauce (test soy sauce) was prepared from the fermented DFSM slurry after a 30 day cultivation at 60 °C and a 60 day ripening at 45 °C. Free amino acid (AA) and organic acid contents in the soy sauce increased in proportion to the fermentation period, whereas ammonium decreased proportionally. Mg and Ca contained in the soy sauce decreased proportionally during fermentation and were lower than those in the non-fermented DFSM extract (control). Spectral absorbance of soy sauce prepared from the fermented DFSM slurry was maximal at 430 nm and increased slightly in proportion to the fermentation period. The aroma and flavor of the test soy sauce were significantly different from those of traditional Korean soy sauce. Conclusively, soy sauce may be prepared directly from the fermented DFSM slurry without meju-preparing process and fermentation period may be a factor for control of soy sauce quality.

    Full Text Available Pullulan, with its excellent characteristics of film-forming, water solubility, and biodegradability, is attracting more and more attention in agricultural products preservation. However, high pullulan production cost largely restricts its widely application due to its low production. In order to improve pullulan production by Aureobasidium pullulans NCPS2016, the medium was optimized using single factor experiment and response surface methodology. Based on the single factor experiments, the contents of soybean meal hydrolysates (SMHs, (NH42SO4, and K2HPO4·3H2O were considered to be main factors influencing the extracellular polysaccharide (EPS production, and were further optimized by Box–Behnken design. The optimal content of SMHs of 7.71 g/L, (NH42SO4 of 0.35 g/L, and K2HPO4·3H2O of 8.83 g/L were defined. Finally, EPS production of 59.8 g/L was obtained, 39% higher in comparison with the production in the basal medium. The purified EPS produced by NCPS2016 was confirmed to be pullulan. This is the first time fructose is reported to be the optimal carbon source for pullulan production by Aureobasidium pullulans, which is of great significance for the further study of the mechanism of the synthesis of pullulan by NCPS2016. Also, the results here have laid a foundation for reducing the industrial production cost of pullulan.

    Full Text Available Soybean, Glycine max (L. Merr. (Leguminoseae, is known as golden bean. It contains vegetable protein, oligosaccharide, dietary fiber, vitamins, isoflavones and minerals. Earlier studies have demonstrated a cholesterol lowering, skin protective, antitumour, antidiabetic and antioxidative potential of soybean. Soy isoflavones are also utilized as estrogen replacement therapy in postmenopausal women. The present study was undertaken to investigate the effect of soybean on memory of mice when consumed along with diet. Soybean was administered chronically for 60 consecutive days as three soybean diets viz. Soy2, Soy5, Soy10. These diet contains soybean in normal diet at concentration of 2%, 5%, 10% w/w respectively. Passive avoidance paradigm and elevated plus maze served as exteroceptive behavioral models for testing memory. Alprazolam (0.5 mg/kg; i.p. induced amnesia served as interoceptive behavioral model. The administration of soybean significantly reversed alprazolam-induced amnesia in a dose-dependent manner as indicated by the increased step down latency of mice using passive avoidance paradigm and increased transfer latency using elevated plus maze. Theses results suggest that consumption of soybean in diet may not only improve memory but also reverse the memory deficits, owing to its multifarious activities. It would be worthwhile to explore the potential of this nutrient in the management of Alzheimer′s disease.

    Poor infant and young child feeding (IYCF) practices in the first 2 years of age are among major causes of childhood malnutrition, in developing countries including Ethiopia. It results in irreversible outcomes of stunting, poor cognitive development, and significantly increases risks of many chronic and infectious diseases. This study was intended to assess factors associated with minimum meal frequency and minimum dietary diversity practice among children aged 6-23 months in the predominantly agrarian society of Bale zone, Southeast Ethiopia. A community based cross sectional study was employed from January to June 2016. An interviewer administered, pretested and structured questionnaire was used to collect data. Multi-stage sampling followed by a systematic random sampling technique was used to include study subjects. Data was entered using Epi info version 3.5.3 and analyzed by SPSS version 20. In the logistic regression, both bivariate and multivariate analyses were carried out to identify factors associated with minimum meal frequency and minimum dietary diversity scores.

    Full Text Available Prebiotic fructans are nondigestible carbohydrates with numerous health benefits. Soybean is a rich source of phytonutrients such as isoflavones. The objective of this study was to evaluate the chemopreventive effects of prebiotics (Synergy1 and soybean meal (SM at 5% and 10% levels alone and in combination on azoxymethane- (AOM- induced colon carcinogenesis. After one wk of acclimatization, Fisher 344 male rats (N=90 were randomly assigned to 9 groups (n=10. Control rats (C were fed AIN-93G/M. Two s/c injections of AOM were administered to rats at 7 and 8 wk of age at 16 mg/kg body weight. Rats were killed by CO2 asphyxiation at 45 wk. Tumor incidence (% in treatment groups ranged from 40 to 75 compared to 100 in C. Results indicate that feeding prebiotics and soybean in combination significantly reduced incidence of AOM-induced colon tumors with implications for food industry in the food-product development.

    Full Text Available Background & objectives: Iron deficiency (ID affects a large number of women in India. An inverse relationship exists between iron (Fe status and Fe absorption. Dietary inhibitory and enhancing factors exert a profound influence on bioavailability of Fe. Although the current recommended dietary allowance (RDA for Fe is based on 8 per cent bioavailability, it is not clear if this holds good for the usual highly inhibitory Indian diet matrix. This study was aimed to determine Fe absorption from several habitually consumed south Indian food and to evaluate the interaction of Fe status with absorption. Methods: Four Fe absorption studies were performed on 60 apparently healthy young women, aged 18-35 years. Based on blood biochemistry, 45 of them were ID and 15 were iron replete (IR. The habitual meals assessed were rice, millet and wheat based meals in the ID subjects and rice based meal alone in the IR subjects. Each subject received the test meal labelled with 3 mg of [57] Fe and Fe absorption was measured based on erythrocyte incorporation of isotope label 14 days following administration. Results: Mean fractional Fe absorption from the rice, wheat and millet based meals in the ID subjects were 8.3, 11.2 and 4.6 per cent, respectively. Fe absorption from the rice-based meals was 2.5 per cent in IR subjects. Interpretation & conclusions: Fe absorption is dictated by Fe status from low bioavailability meals. Millet based meals have the lowest bioavailability, while the rice and wheat based meals had moderate to good bioavailability. In millet based meals, it is prudent to consider ways to improve Fe absorption.

    The content of sulfur amino acid (SAA) in a meal affects postprandial plasma cysteine concentrations and the redox potential of cysteine/cystine. Because such changes can affect enzyme, transporter, and receptor activities, meal content of SAA could have unrecognized effects on metabolism during the postprandial period. This pilot study used proton NMR (1H-NMR) spectroscopy of human plasma to test the hypothesis that dietary SAA content changes macronutrient metabolism. Healthy participants (...

    The purpose of this pilot study was to determine whether macronutrient content (low-fat v. high-fat diet) influences an indicator of advanced glycation end products (AGE), N(ε) carboxymethyl-lysine (CML), in the context of a 1-d, high-AGE diet. The effect of the diets on inflammatory markers was also assessed. A total of nineteen overweight and obese adults (nine men and ten women) without known disease were recruited to participate in a crossover challenge of a high-fat, high-AGE (HFHA) and low-fat, high-AGE (LFHA) diet. In each phase patients had fasting blood drawn, followed by consumption of a high-fat or low-fat breakfast test meal, then three postprandial blood draws at 1, 2 and 3 h after consuming the test meal. After consuming high-AGE meals for the remainder of the day, participants returned the next day for a follow-up analysis. A different pattern in the 3-h post-meal CML and soluble receptor for AGE response to the two diets was observed (P=0·01 and 0·05, respectively). No change in serum CML was observed following consumption of a LFHA breakfast (535 (25th-75th percentile 451-790) to 495 (25th-75th percentile 391-682) ng/ml; P=0·36), whereas a rise in CML occurred after the HFHA breakfast (463 (25th-75th percentile 428-664) to 578 (25th-75th percentile 474-865) ng/ml; P=0·05). High sensitivity C-reactive protein and high molecular weight adiponectin were not affected by either diet. These findings suggest that dietary CML may not be as important in influencing serum CML as other dietary factors. In addition, acute exposure to dietary CML may not influence inflammation in adults without diabetes or kidney disease. This is contrary to previous findings.

    Young male Wistar rats (86.9 +- 0.96 g) were fasted for 24 hours and then offered a single meal (intake of 1 to 2.5 g) of 15 N-labelled barley (5.34 atom% 15 N excess). The test meal also contained Cr 2 O 3 (20 mg/g). Groups of five animals were killed 0.5; 1; 1.5; 2; 2.5; 4; 6 and 8 hours after removal of food. The contents of different regions of the digestive tract (stomach, proximal, middle and distal third of small intestine, large intestine) and feces were analyzed for Cr 2 O 3 and for N and 15 N abundance in both a TCA soluble and a TCA precipitable fraction. The distribution patterns of Cr 2 O 3 and 15 N along the digestive tract were very similar. If the disappearance of 15 N from the contents of the small and of the large intestines was expressed as a proportion of the gastric outflow of 15 N, a disappearance rate of 90% was found. On the basis of isotopic dilution the proportion of dietary nitrogen in digesta was calculated. The results illustrated the intensive dilution of dietary nitrogen by endogenous secretions in all regions of the digestive tract. In the distal small intestine endogenous nitrogen accounted for 70% of total nitrogen. 17 mg endogenous N were produced by the stomach within 8 hours after the single meal. The results show the value of the method in determining the true digestibility of nitrogen in 15 N-labelled feedstuffs more accurately than with classical methods and in providing an insight into the dynamics of nitrogen absorption and secretion in the digestive tract.

    To examine how different definitions of meals and snacks can affect the associations of meal frequency (MF) and snack frequency (SF) with dietary intake and adiposity measures. Based on 7 d weighed dietary record data, all eating occasions providing ≥210 kJ of energy were divided into meals or snacks based on contribution to energy intake (≥15 % or snacks, SF was associated with higher intakes of confectionery and alcohol, lower intakes of cereals, protein, fat and dietary fibre, and lower HDI (except for SF based on energy contribution in women) and MDS. After adjustment for potential confounders, MF based on time, but not MF based on energy contribution, was positively associated with BMI and waist circumference in men only. SF was positively associated with BMI and waist circumference, irrespective of the definition of snacks. Higher SF was consistently associated with lower diet quality and higher adiposity measures, while associations with MF varied depending on the definition of meals and sex.

    An experiment was conducted to determine the effects of processing of soybean meal (SBM) and 00-rapeseed meal (RSM) on N solubilization in chyme, CP digestibility along the small intestine, metabolic load as determined by organ weight, body composition, and growth performance in growing pigs. The SBM and RSM were processed by secondary toasting (at 95°C for 30 min) in the presence of lignosulfonate, resulting in processed SBM (pSBM) and processed RSM (pRSM) as a model for overprocessed protein sources. Fifty-four growing pigs were each fed 1 of the 6 experimental diets. Four of the diets contained SBM, pSBM, RSM, or pRSM as the sole protein source. The remaining 2 experimental diets contained pSBM or pRSM and were supplemented with crystalline AA to the same standardized ileal digestible AA levels as the SBM or RSM diet. Pigs were slaughtered at 40 kg, and organ weights were recorded. The organs plus blood and empty carcass were analyzed for CP content. The small intestine was divided into 3 segments, and chyme samples were taken from the last meter of each segment. Chyme of the SBM, pSBM, RSM, and pRSM diets was centrifuged to separate the soluble and insoluble fractions, and N content was determined in the latter. The amount of insoluble N as a fraction of N in chyme at each small intestinal segment was not affected by processing. Diet type, comprising effects of processing and supplementing crystalline AA, affected ( < 0.05) the G:F and standardized ileal digestibility (SID) of CP. Processing reduced G:F from 0.56 to 0.38 for SBM and 0.49 to 0.40 for RSM, whereas supplementing crystalline AA increased G:F to the level of the SBM and RSM diets. Processing reduced the SID of CP from 87.2% to 69.2% for SBM and 71.0% to 52.2% for RSM. Diet type affected ( < 0.05) the CP content in the empty body, with processing reducing this content from 170 to 144 g/kg empty BW for SBM and 157 to 149 g/kg empty BW for RSM and supplementing crystalline AA restoring this content

    Understanding different patterns of fish consumption is an important component of the assessment of risk from contaminants in fish. While there have been extensive studies of fish consumption in Western cultures, less attention has been devoted to the role of fish and meat in the diets of people in other cultures. A survey of 212 people living in Singapore was conducted to examine the relative importance of fish, shellfish, and other meat in their diets and to ascertain whether there were differences as a function of age, income, education or gender. As expected, fish and shellfish played an important role in their daily diets. On average, people ate fish in about 10 meals a week, chicken for eight meals, and shrimp and pork for about six meals each. While nearly 8% never ate fish, 18% ate fish at all 21 meals a week and over 20% ate shellfish for all 21 meals. Income explained about 14% of the variation in the number of fish meals consumed, and age explained about 8% of the variation in number of chicken meals per week. There were no gender differences in the number of meals of each type. People less than 26 years old ate significantly more pork, chicken, and other meat meals and fewer shellfish meals than older people. People with higher incomes ate significantly more fish meals than those with lower incomes. Chinese individuals ate significantly more meals of pork, chicken, and other meat than other ethnic groups, and they ate only 26% of their meals at home, while others ate 33% of their meals at home. The data indicate a great deal of variation in the number of meals of fish, shellfish, and other meats eaten by the people interviewed, making dietary and risk assessments challenging

    Meal planning could be a potential tool to offset time scarcity and therefore encourage home meal preparation, which has been linked with an improved diet quality. However, to date, meal planning has received little attention in the scientific literature. The aim of our cross-sectional study was to investigate the association between meal planning and diet quality, including adherence to nutritional guidelines and food variety, as well as weight status. Meal planning, i.e. planning ahead the foods that will be eaten for the next few days, was assessed in 40,554 participants of the web-based observational NutriNet-Santé study. Dietary measurements included intakes of energy, nutrients, food groups, and adherence to the French nutritional guidelines (mPNNS-GS) estimated through repeated 24-h dietary records. A food variety score was also calculated using Food Frequency Questionnaire. Weight and height were self-reported. Association between meal planning and dietary intakes were assessed using ANCOVAs, while associations with quartiles of mPNNS-GS scores, quartiles of food variety score and weight status categories (overweight, obesity) were evaluated using logistic regression models. A total of 57% of the participants declared to plan meals at least occasionally. Meal planners were more likely to have a higher mPNNS-GS (OR quartile 4 vs. 1 = 1.13, 95% CI: [1.07-1.20]), higher overall food variety (OR quartile 4 vs. 1 = 1.25, 95% CI: [1.18-1.32]). In women, meal planning was associated with lower odds of being overweight (OR = 0.92 [0.87-0.98]) and obese (OR = 0.79 [0.73-0.86]). In men, the association was significant for obesity only (OR = 0.81 [0.69-0.94]). Meal planning was associated with a healthier diet and less obesity. Although no causality can be inferred from the reported associations, these data suggest that meal planning could potentially be relevant for obesity prevention.

    Full Text Available Dietary fat plays a major role in obesity, lipid metabolism, and cardiovascular diseases. To determine whether the intake of different types of dietary fats affect the muscle fiber types that govern the metabolic and contractile properties of the skeletal muscle, we fed male Wistar rats with a 15% fat diet derived from different fat sources. Diets composed of soybean oil (n-6 polyunsaturated fatty acids (PUFA-rich, fish oil (n-3 PUFA-rich, or lard (low in PUFAs were administered to the rats for 4 weeks. Myosin heavy chain (MyHC isoforms were used as biomarkers to delineate the skeletal muscle fiber types. Compared with soybean oil intake, fish oil intake showed significantly lower levels of the fast-type MyHC2B and higher levels of the intermediate-type MyHC2X composition in the extensor digitorum longus (EDL muscle, which is a fast-type dominant muscle. Concomitantly, MyHC2X mRNA levels in fish oil-fed rats were significantly higher than those observed in the soybean oil-fed rats. The MyHC isoform composition in the lard-fed rats was an intermediate between that of the fish oil and soybean oil-fed rats. Mitochondrial uncoupling protein 3, pyruvate dehydrogenase kinase 4, and porin mRNA showed significantly upregulated levels in the EDL of fish oil-fed rats compared to those observed in soybean oil-fed and lard-fed rats, implying an activation of oxidative metabolism. In contrast, no changes in the composition of MyHC isoforms was observed in the soleus muscle, which is a slow-type dominant muscle. Fatty acid composition in the serum and the muscle was significantly influenced by the type of dietary fat consumed. In conclusion, dietary fat affects the expression of genes related to the contractile and metabolic properties in the fast-type dominant skeletal muscle, where the activation of oxidative metabolism is more pronounced after fish oil intake than that after soybean oil intake.

    The current study aimed to assess Uruguayan consumers' accounts of their own need to change their dietary patterns, their intended changes and the barriers related to doing so, and to compare the intentions and barriers with the recommendations of the national dietary guidelines. An online survey with 2381 Uruguayan employed adults, aged between 18 and 65 years, 65 % females, was conducted. Participants had to answer two open-ended questions related to changes they could make in the foods they eat and/or the way in which they eat to improve the quality of their diet and the reasons why they had not implemented those changes yet. Content analysis using inductive coding by two researchers was used to analyse the responses. Consumers mainly intended to change consumption of types of foods, particularly eating more fruits, vegetables and legumes and consuming less flour, but also intended to alter their eating patterns. Lack of time and the fact that healthy foods are perceived as being more expensive than unhealthy foods were major barriers to behaviour change. Some of the recommendations of the dietary guidelines, particularly those related to enjoying cooking and meals and engaging in it as a social activity, were not represented in consumer accounts. Accompanying policies to the dietary guidelines need to underline the importance of changes in dietary patterns, including greater enjoyment and sharing food preparation and meals in the company with others, address misconceptions about flour, and provide concrete, consumer-derived recommendations on how to enact the guidelines.

    To identify sociodemographic characteristics associated with frequency of consuming home-cooked meals and meals from out-of-home sources. Cross-sectional analysis of a population-based cohort study. Frequency of consuming home-cooked meals, ready meals, takeaways and meals out were derived from a participant questionnaire. Sociodemographic characteristics regarding sex, age, ethnicity, working overtime and socio-economic status (SES; measured by household income, educational attainment, occupational status and employment status) were self-reported. Sociodemographic differences in higher v. lower meal consumption frequency were explored using logistic regression, adjusted for other key sociodemographic variables. Cambridgeshire, UK. Fenland Study participants (n 11 326), aged 29-64 years at baseline. Eating home-cooked meals more frequently was associated with being female, older, of higher SES (measured by greater educational attainment and household income) and not working overtime. Being male was associated with a higher frequency of consumption for all out-of-home meal types. Consuming takeaways more frequently was associated with lower SES (measured by lower educational attainment and household income), whereas eating out more frequently was associated with higher SES (measured by greater educational attainment and household income) and working overtime. Sociodemographic characteristics associated with frequency of eating meals from different out-of-home sources varied according to meal source. Findings may be used to target public health policies and interventions for promoting healthier diets and dietary-related health towards people consuming home-cooked meals less frequently, such as men, those with lower educational attainment and household income, and overtime workers.

    Full Text Available The aim of this paper is to trace genetically modified soybean in food and feed products present on the Romanian market by using molecular extraction, identification and quantification methodologies. Nine samples (3 food samples, 5 soybean samples and 1 soybean meal were analysed using the classical and real-time polymerase chain reaction (PCR method. DNA-genetically modified organism (GMO was not detected in two of the three analysed samples (food products. However, it could be found in four samples ranging below the limit of 0.9%, and in three samples, above the limit of 0.9%. The results obtained through real-time PCR quantification show that DNA-RRS was detectable in different amounts in different samples: ranging between 0.27% and 9.36% in soy beans, and reaching 50.98% in soybean meal. The current research focuses on how products containing GMO above the limit (it is common knowledge that it is necessary to label the products containing more than 0.9% Genetically Modified DNA are differentiated on the market with a view to labeling food and feed products in terms of the accidental presence of approved genetically modified plants. The benefits brought by genetic engineering in obtaining genetically modified organisms can be balanced with their public acceptance and with certain known or unknown risks that they can bring.

    The associations between eating frequency and diet quality are inconclusive, which might be a result of different effects of meal frequency and snack frequency. This cross-sectional study examined the associations of eating frequency, meal frequency, and snack frequency with diet quality, based on data from the National Health and Nutrition Examination Survey 2003-2012. Dietary intake was assessed in 19,427 US adults aged 20 years or older, using two 24-hour dietary recalls. All eating occasions providing ≥50 kcal were divided into either meals or snacks on the basis of contribution to daily energy intake (≥15% or snack frequency (independent variables) with dietary intake variables (dependent variables). Higher eating frequency was modestly and positively associated with higher HEI-2010 in both men and women; one additional eating occasion per day increased HEI-2010 by 1.77 points in men and 2.22 points in women (both Psnack frequency were also modestly and positively associated with HEI-2010 in both sexes, irrespective of the definition of meals and snacks. However, the associations were stronger for meal frequency than for snack frequency; one additional meal per day increased HEI-2010 by 2.14 to 5.35 points, and one additional snack per day increased HEI-2010 by 1.25 to 1.97 points (all Psnack frequency were modestly associated with better diet quality.

    To examine the associations of meal frequency (MF) and snack frequency (SF) with diet quality. Dietary intake was assessed using two 24 h dietary recalls. All eating occasions providing ≥210 kJ of energy were divided into meals or snacks on the basis of contribution to energy intake (≥15 % or snack, respectively), there were no associations for SF based on self-report or time. In analyses in which only plausible energy reporters (3425 children and 3753 adolescents) were included, similar results were obtained. In a representative sample of US children and adolescents, MF was associated with better diet quality, while the associations for SF varied depending on the definition of snacks. The findings highlight the importance of applying different definitions of meals and snacks when assessing the impact of dietary patterns on health.

    Meal and snack patterns are associated with energy and nutrient intakes and consequently health and nutritional status. The aim of this paper is to describe the percentage of daily energy intake from meals and afternoon snack among Malaysian adults. The study included a representative sample of adults aged 18-59 years (n=7349) from a nationwide Food Consumption Survey conducted by the Ministry of Health. Information on dietary intake was obtained using a one day 24-hour diet recall (24-HDR). Dietary data on 6886 adults were analysed using Nutritionist ProTM and statistical analysis was carried out using the SPSS 13.0. The median percentage of daily energy intake is reported only for adults consuming meals and afternoon tea and by socio-demographic characteristics as well as body mass index (BMI) status. More than 80% of Malaysian adults consumed morning meals, lunch and dinner and 54% reported having afternoon tea. The median percentage of energy intake from morning meals, lunch, dinner and afternoon tea was 29.9%, 30.5%, 32.4% and 17%, respectively. There were variations in the median percentage of energy from meals and snacks according to the socio-demographic variables and BMI status. It is important to understand the eating patterns of Malaysians as the information can assist in efforts to address obesity and diet-related chronic diseases among adults.

    We have recently noted that ingestion of dietary lipid (in the form of heavy whipping cream) leads to greater oxidative stress than dietary carbohydrate (in the form of dextrose), when consumed in isocaloric amounts. In the present investigation we attempted to replicate our work and also to determine the oxidative stress response to dextrose and lipid meals of two different kilocalorie (kcal) amounts. Nine young (22 +/- 2 years), healthy men consumed in a random order, cross-over design one of four meals/drinks: dextrose at 75 g (300 kcals), dextrose at 150 g (600 kcals), lipid at 33 g (300 kcals), lipid at 66 g (600 kcals). Blood samples were collected Pre meal, and at 30 min, 60 min, 120 min, and 180 min post meal. Samples were assayed for glucose, triglycerides (TAG), malondialdehyde (MDA), and hydrogen peroxide (H2O2). Area under the curve (AUC) was calculated for each variable, and a 4 x 5 ANOVA was utilized to further analyze data. A meal x time effect (p = 0.0002) and a time effect was noted for glucose (p Pre, 1 hr, 2 hr, and 3 hr). The dextrose meals primarily contributed to this time effect. No other effects were noted for glucose (p > 0.05). A meal effect was noted for TAG (p = 0.01; 66 g lipid meal > 75 g and 150 g dextrose meals). No other effects were noted for TAG (p > 0.05).

Control diet contained fish meal (20%, soybean meal (40%, wheat flour (27%, corn gluten meal (5%, fish oil (2% and soy oil (2% as main ingredients. Following a 24 h fasting, 540 fish with a mean body weight of 11.8 g were randomly allotted to 6 groups in triplicate, whereby 18 tanks (0.4×0.6×0.36 cm, water volume of 66 L were prepared. The feeding experiment lasted for 8 weeks. Fish group fed the control diet showed the lowest weight gain (WG and feed efficiency (FE among treatments. The WG was, however, not significantly different (p>0.05 from that of fish group fed MHP0.5. Fish group fed MHP2.0 showed the highest WG and FE of which values were not significantly different from those of fish groups fed diets MHP1.0 and MHP1.5 as well as MCP (p>0.05 except fish groups fed control and MHP0.5. Aspartate aminotransferase was significantly decreased with an increase in available P, while alanine aminotransferase did not show a significant difference among treatment. The highest inorganic P in plasma was observed in fish fed MHP2.0. From the present results, a second-order regression analysis revealed that the optimal dietary MHP level and the AP requirement were found to be 1.62% and 0.7%, respectively.

    The objectives of this study were to evaluate the effect of different dietary levels of tropical marine brown macroalgae, Sargassum cristaefolium meal (SCM) on growth performance and feed utilization efficiency of juvenile white shrimp, Litopenaeus vannamei (mean initial weight 2.65±0.1 g). The algae were collected from Bandengan Coast, Jepara, Indonesia. The study used a completely randomized design with 5 treatments of dietary different S. cristaefolium meal levels (0, 10, 20, 30, and 40 g algae meal/kg feed) in triplicates. The results showed that the different levels of dietary SCM did not significantly affect (P>0.05) average daily growth (ADG;.204-224 mg/day) and survival (80-97%) of the shrimp after a 42-day feeding period. However, the test diets significantly affected (P<0.05) feed intake (FI), feed conversion ratio (FCR), and protein efficiency ratio (PER). Better FCR (2.13) and PER (1.34) was found by the diet with 2% SCM compared to the control diet (no SCM) (FCR 3.42 and PER 0.81). This finding indicates that the supplement of dietary 2% SCM (20 g/kg feed) can increase the feed utilization efficiency up to 62% or reduce the FCR up to 38% without any adverse in growth performance.

    Full Text Available Trade liberalization is closely related to the opening of market access for Indonesian products to the world and vice versa. Since the soybean trade out of BULOG control began in 1998, soybean imports increased very rapidly (Sudaryanto and Swastika, 2007. This research aims to determine the general picture of soybean economy, factors analyses that influence the economic performance of Indonesian soybean and findings the alternative of policies that can reduce soybean imports in Indonesia. Methods of data analysis are descriptive analysis, 2SLS simultaneous equations, and simulation of policy alternatives. Results of the analysis of the factors that affect the economic performance of Indonesian soybean, consists of 1 The area of soybean harvest is influenced significantly by the price of domestic soybean and domestic prices of corn, 2 Productivity soybean influenced significantly by the domestic prices of soybean and fertilizer prices, 3 soybean demand influenced significantly by population, domestic prices of soybean, 4 domestic prices of soybean significantly affected by world prices of soybean, exchange rates, and soybean supply, 5 Imports of soybean influenced significantly by the domestic demand of soybean and soybean production. Therefore, policy scenarios should be made to reduce soybean imports, including by carrying out the expansion of soybean harvest policy, the policy of increasing the productivity of soybean, the policy of subsidizing the price of fertilizer.

    Nutrition transition to high energy-dense foods has been implicated as the major causes of diet related diseases. Plantain-based dough meals supplemented with soybean cake and cassava fibre were developed by combining them in different proportions using response surface methodology. The flour blends were analyzed for the nutritional composition while the glycaemic index, antidiabetic potentials and protein digestibility of the dough meals were determined in wistar rats. The nutritional and essential amino acid contents of the flour blends were comparable to that of cerolina (a commercially available food product commonly recommended for diabetic patients). The rats fed with the formulated dough meals had lower glycaemic index and glycaemic load, and the blood glucose was significantly reduced compared to cerolina and metformin (a synthetic antidiabetic drug). All the plantain-based dough meals were comparable to cerolina and metformin in terms of nutritional quality and blood glycaemic control activities, respectively. Hence, the formulated plantain-based dough meals have potential to be used for the prevention and management of diabetes mellitus.

    Phosphorus of plant-based feedstuffs for monogastric animals is mainly in the form of phytic P, which has a very low bioavailability. The nondigested phytic P may contribute to P pollution. Furthermore, phytic acid may reduce digestibility of other minerals and protein. This study evaluated effects of the microbial 6-phytase RONOZYME HiPhos on apparent ileal digestibility of P, phytic acid, Ca, CP, energy, and AA in six 60-d-old ileorectal anastomosed pigs. In a duplicated 3 × 3 Latin square design, pigs had free access to alternatively a corn (Zea mays)-soybean (Glycine max) meal-barley (Hordeum vulgare)-based diet or this diet supplemented with RONOZYME HiPhos at either 500 units/kg (RH500) or 1000 units/kg (RH1000). Pigs fed diets supplemented with RH500 or RH1000 increased (P phytase increased apparent ileal digestibility of these indispensable minerals and phytate. The phytase increased digestibility of CP and indispensable AA indicating a better availability of plant-based proteins.

    The influences of zinc in a meal and usual zinc intake on zinc retention and turnover were investigated in 7-wk-old male rats fed diets containing 12-151 mg Zn/kg for 3 wk before and after consuming a 65 Zn-labeled meal containing ZnCl 2 . Retention corrected to zero time and turnover rate were determined by whole-body counting. Percent zinc retention was inversely proportional to the natural logarithm of the meal zinc, between 0.09 and 26 mumol. In comparison to lower doses, higher doses resulted in lower percent retention but greater amounts of zinc retained. Although the latter relationship was slightly curvilinear, there was no indication of a limited capacity for zinc retention with high doses. However, doses above 4 mumol resulted in higher turnover rates in rats accustomed to lower zinc intakes. Percent retention and the reciprocal of the turnover rate were proportional to the reciprocal of the dietary zinc concentration. The greatest differences in retention and turnover occurred between 12 and 26 mg Zn/kg diet. The zinc dose in a meal and the usual dietary zinc separately influenced percent zinc retention. These factors also interacted, such that greater dose effects were observed at lower zinc intakes and greater dietary zinc effects were observed at lower doses

    Full Text Available A four-month growth trial was carried out in order to evaluate performance and quality traits of juvenile shi drum fedwith two isonitrogenous and isoenergetic diets having different amounts of vegetable products (Vegetable diet vs. Controldiet. Compared to the Control diet, the Vegetable diet was formulated by increasing the replacement of fish meal (14%with soybean and cereal products, and fish oil (12% with a mixture of vegetable oil. On June, 4 groups of 225 fish (2replicates per dietary treatment were sorted according to live weight and reared in fibreglass tanks over a four- monthlong experimental period. Fish were hand fed to apparent satiety. Offered feed, growth parameters and feed efficiencywere recorded as productive performance. At the end of the trial (October biometric, chemical and reological traits wereexamined to assess fish quality. The dietary treatments showed similar productive performance. The relatively high inclusionof vegetable sources led to a significant modification of body shape, mesenteric fat and viscera weight. Among qualitytraits, Vegetable diet-fed fish demonstrated a significantly lower whole body and fillet crude protein content.Yellowness value of the cooked fillet was significantly lower in the Control diet-fed fish, whereas fillet texture was similar.The results of this research showed that shi drum is a suitable candidate for Mediterranean marine aquaculture andits dietary formulation might include at least the amount of vegetable sources used in this trial.

Cobb 500 broilers (n=400, assigned to 2 groups, were fed with isocaloric and isonitrogenous corn-soybean meal control diets (C or corn-WS-soybean meal diets (WS, where corn was partially replaced (50% with WS. At 35 d, sixteen broilers per group were selected for blood sampling, gastrointestinal (GIT measurements, digesta pH and ileum microflora analysis. There was no effect (P>0.05 of the dietary WS inclusion on blood biochemistry parameters, GIT development and digesta pH of broilers. In our study, dietary WS significantly reduced the ileal population of Enterobacteriaceae (-1.38%; P<0.0001 and E. coli (-1.16%; P=0.020, and increased the Lactobacillus spp. (+1.07%; P=0.014 compared with the C diet. In conclusion, feeding white sorghum, as partial substitute of corn in broiler diets, did not affect blood parameters, digestive organ size and digesta pH, that support the obtained performance. In addition, sorghum had a positive effect of the ileal microflora increasing the beneficial bacterial Lactobacillus spp.

    Full Text Available The effect of replacing of 0; 0.33; 0.67 and 1.0 (kg/kg of soybean meal (SBM by undecorticated castor seed meal treated with calcium oxide (CMT - 60 g/kg was evaluated on performance and efficiency of nutrient utilization in dairy cows. Sixteen Holstein and crossbred cows were distributed in four 4 × 4 latin squares. Animals received concentrated feed at a ratio of 1 kg for 3 kg of milk produced, in the natural matter. The diets had the same amount of nitrogen (150.4 g crude protein/kg DM, containing 325.6 g of concentrated feed/kg DM. There was no effect on the serum concentration of transaminase and the animals showed no clinical symptoms of intoxication by ricin. The intake of DM, crude protein (CP and non-fibrous carbohydrates (NFC reduced from 0.67 replacement of SBM by CMT. The intake of neutral detergent fibers corrected for ash and protein (NDFap increased from 0.33 replacement of SBM with CMT. Although the digestibility of dietary components decreased from 0.33 replacement, the intake of digestible components only reduced from 0.67 replacement. Because of the reduction of digestible energy, the synthesis of microbial CP and the utilization efficiency of rumen-degradable protein for the synthesis of microbial CP reduced with full replacement of SBM by CMT. Milk yield, milk composition, daily variation of body weight and the efficiency of utilization of the nutrients for the synthesis of N in milk reduced from 0.67 replacement of SBM by CMT. Castor seed meal treated with calcium oxide can replace up to 0.33 of SBM (50 g/kg DM diet DM in the diet of dairy cows with an average milk production of 20 kg/day.

Hyperinsulinemia, insulin resistance, androgen excess, ovulatory dysfunction, polycystic ovaries, gonadotropin abnormalities, obesity, adipose tissue dysfunction, difficulty to conceive and high-risk pregnancy are the most common PCOS-associated complications. The aim of this review was to describe and evaluate the effects of dietary interventions on PCOS-associated outcomes and to provide some evidence-based dietary advice for use in clinical practice. There is no optimal diet or macronutrient composition for PCOS. However, lifestyle modification, including a small-to-moderate weight loss of 5–10% (combined diet with regular physical activity with any dietary pattern of choice, depending on the individuals’ preferences, culture, habits and metabolic needs (ie, Mediterranean diet, Dietary Approaches to Stop Hypertension [DASH] diet or moderately low-carbohydrate diets [30–45% of energy], as well as alternative dietary interventions, including small, frequent meal (five to six meals daily consumption at regular times, with the majority of carbohydrates consumed at lunch time or equally distributed throughout the day, seems to offer the evidence-based first-line strategy for the management of PCOS symptoms and insulin resistance. No conclusions can be drawn at this time for high protein diets, polyunsaturated fatty acids or micronutrient supplementation.

    Soy protein regulates adiponectin and peroxisome proliferator-activated receptor alpha (PPARalpha) in some species, but the effect of dietary soy protein on adiponectin and PPARalpha in the pig has not been studied. Therefore, the objective of this study was to determine whether soya bean meal reduction or replacement influences serum adiponectin, adiponectin mRNA, serum metabolites and the expression of PPARalpha and other genes involved in lipid deposition. Thirty-three pigs (11 pigs per treatment) were subjected to one of three dietary treatments: (i) reduced crude protein (CP) diet containing soya bean meal (RCP-Soy), (ii) high CP diet containing soya bean meal (HCP-Soy) or (iii) high CP diet with corn gluten meal replacing soya bean meal (HCP-CGM) for 35 days. Dietary treatment had no effect on overall growth performance, feed intake or measures of body composition. There was no effect of dietary treatment on serum adiponectin or leptin. Dietary treatment did not affect the abundance of the mRNAs for adiponectin, PPARalpha, PPARgamma2, lipoprotein lipase or fatty acid synthase in adipose tissue. The mRNA expression of PPARalpha, PPARgamma2, lipoprotein lipase or fatty acid synthetase in loin muscle was not affected by dietary treatment. In liver tissue, the relative abundance of PPARalpha mRNA was greater (p Soy diets when compared to pigs fed RCP-Soy or HCP-CGM diets. Hepatic mRNA expression of acyl-CoA oxidase or fatty acid synthase was not affected by dietary treatment. Western blot analysis indicated that hepatic PPARalpha protein levels were decreased (p Soy diets when compared to pigs fed the HCP-Soy diets. These data suggest that increasing the soy protein content of swine diets increases hepatic expression of PPARalpha without associated changes in body composition.

    Full Text Available ABSTRACT The 4-week study was conducted with 180 Lohmann Brown layers (52 weeks of age. The layers were assigned to three groups (C, E1 and E2. The basal diet (group C consisted mainly of corn, soybean meal and corn gluten, and contained 19% crude protein and 11.58 MJ/kg metabolizable energy. The diets for groups E1 and E2 differed from group C by the inclusion of 5% flax meal and of dietary antioxidants. The concentration of α-linolenic acid in the fat of E1 and E2 diets was almost 10 times higher than in group C. E1 diet was supplemented with vitamin E (100 mg/kg feed, DM, while E2 diet was supplemented with 2% grape seed meal (polyphenols: 630.890 µg gallic acid equivalents/g sample; flavonoids: 5.065 µg rutin equivalents/g sample; antioxidant capacity: 28.468 mM trolox equivalents/g sample. The antioxidant capacity of E2 was higher than in C, but lower than in E1. Haugh units of the eggs (18 eggs/group harvested during the last experimental week were not significantly different among groups. The ω-6/ω-3 polyunsaturated fatty acids (PUFAs ratio in the fat from the eggs was 4.46 ± 0.11 (E1 and 4.52 ± 0.21 (E2, three times lower (p<0.05 than the control group (14.70 ± 0.43.

    The objective of this study was to evaluate changes in ruminal microorganisms and fermentation parameters due to dietary supplementation of soybean and linseed oil alone or in combination. Four dietary treatments were tested in a Latin square designed experiment using four primiparous rumen-cannulated dairy cows. Treatments were control (C, 60 : 40 forage to concentrate) or C with 4% soybean oil (S), 4% linseed oil (L) or 2% soybean oil plus 2% linseed oil (SL) in a 4 × 4 Latin square with four periods of 21 days. Forage and concentrate mixtures were fed at 0800 and 2000 h daily. Ruminal fluid was collected every 2 h over a 12-h period on day 19 of each experimental period and pH was measured immediately. Samples were prepared for analyses of concentrations of volatile fatty acids (VFA) by GLC and ammonia. Counts of total and individual bacterial groups (cellulolytic, proteolytic, amylolytic bacteria and total viable bacteria) were performed using the roll-tube technique, and protozoa counts were measured via microscopy in ruminal fluid collected at 0, 4 and 8 h after the morning feeding. Content of ruminal digesta was obtained via the rumen cannula before the morning feeding and used immediately for DNA extraction and quantity of specific bacterial species was obtained using real- time PCR. Ruminal pH did not differ but total VFA (110 v. 105 mmol/l) were lower (P ruminal NH3-N (4.4 v. 5.6 mmol/l) was greater (P ruminal fluid was substantially lower (P ruminal microorganisms, except proteolytic bacteria, are highly susceptible to dietary unsaturated fatty acids supplementation, particularly when linolenic acid rich oils were fed. Dietary oil effects on ruminal fermentation parameters seemed associated with the profile of ruminal microorganisms.

  9. The potential for eEngineering enhanced functional-feed soybeans for sustainable aquaculture feed

    Full Text Available Aquaculture is the most rapidly growing segment of global animal production that now surpasses wild-capture fisheries production and is continuing to grow 10% annually. Sustainable aquaculture needs to diminish, and progressively eliminate, its dependence on fishmeal-sourced feed from over-harvestedallocated fisheries. Sustainable aquafeed sources will need to be primarily of plant-origin. Soybean is currently the primary global vegetable-origin protein source for aquaculture. Direct exchange of soybean meal for fishmeal in aquafeed has resulted in reduced growth rates due in part to soybean’s anti-nutritional proteins. To produce an aquaculture soybeans for use in aquaculture feeds a new conventional line has been bred termed Triple Null by stacking null alleles for the feed-relevant proteins Kunitz Trypsin Inhibitor, lectin, and P34 allergen. Triple Null is now being further enhanced as a platform to build additional transgene traits for production disease vaccines, altered protein composition, and to produce high levels of -carotene an intrinsic orange-colored aquafeed marker to distinguish the seeds from commodity beans and as the metabolic feedstock precursor of highly valued astaxanthin.

    Whole-grain foods and cereal dietary fiber intake is associated with lower body weight. This may partly result from lower energy utilization of high-fiber diets. In the present study, the impact on ileal excretion of energy and macronutrients in response to a rye bread high-fiber diet compared to a refined wheat low-fiber diet was investigated. Furthermore, the effect of meal frequency on apparent absorption of nutrients was studied for the first time. Ten participants that had undergone ileostomy consumed standardized iso-caloric diets, including low-fiber wheat bread (20 g dietary fiber per day) for 2 weeks followed by high-fiber rye bread (52 g dietary fiber per day) for 2 weeks. The diets were consumed in an ordinary (three meals per day) and a nibbling (seven meals per day) meal frequency in a cross-over design. Ileal effluents were collected during 24 h at the third day of each of the four dietary periods and analyzed for gross energy and nutrient contents. The results showed that intake of rye bread high-fiber diet compared to the refined wheat low-fiber diet caused an increase in ileal excretion of energy and macronutrients. The effect was independent of meal frequency. This suggests that a high intake of rye may result in lower availability of macronutrients for small intestinal digestion and absorption. A regular intake of rye may therefore have implications for weight management.

    Low physical activity has been identified as a major risk factor for the development of feline obesity and diabetes. This study aimed to evaluate the effects of increased meal frequency and dietary water content on voluntary physical activity in cats fed to maintain BW. Ten adult lean neutered male cats were used in 2 tests, both crossover studies composed of a 14-d adaptation period, followed by a 7-d measurement of physical activity from d 15 to d 22 using Actical activity collars. Cats were group housed for most of the day, except for times when they were individually housed in cages to access their diet under a 16:8 h light:dark cycle. In Exp. 1, the difference in voluntary physical activity among cats fed 1, 2, 4, or a random number of meals per day were tested in a 4 × 4 Latin square design in 4 individual rooms. In Exp. 2, the effect of increasing dietary water content on voluntary physical activity was tested in a crossover design including a 5-d phase for fecal and urine collection from d 22 to 27. Cats were randomly assigned to 2 rooms and fed a dry commercial diet with or without added water (70% hydrated) twice daily. Activity levels were expressed as "activity counts" per epoch (15 s). In Exp. 1, average daily activity level for 1-meal-fed cats was lower than 4-meal-fed (P = 0.004) and random-meal-fed (P = 0.02) cats, especially during the light period. The activity level of cats during the dark period was greater in 1-meal-fed cats compared with cats fed 2 meals (P = 0.008) or 4 meals (P = 0.007) daily. Two-hour food anticipatory activity (FAA) before scheduled meal times for 1-meal-fed cats was lower (P meal-fed cats. In Exp. 2, average daily activity level of cats fed the 70% hydrated diet tended to be higher (P = 0.06) than cats fed the dry diet, especially during the dark period (P = 0.007).

    Data from the ongoing, open-cohort Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study were used to describe warm family lunch meals and the association of the lunch composition with total diet quality. 2,095 three-day weighed dietary records, collected between 2004 and 2009, from a 4- to 18-year-old DONALD study subgroup were used. Warm lunch (eating occasions between 11.30 a.m. and 2.29 p.m. including at least one course that is typically consumed warm) was eaten on 68.8% of all record days. Meat lunch (>50%) was predominant, followed by vegetarian (25%), fish (13%) and sweet lunch meals (3%). The prevalence of desserts at lunch was high and beverages were drunk at 80% of lunch meals. A meat lunch was associated with a higher protein (+1.4% energy intake, %E) and fat intake (+1.7%E) than a sweet lunch; also densities of vitamin A, folate and iron were higher. A dessert at lunch decreased protein intake slightly (-0.2%E), but increased carbohydrate (+0.7%E) and added sugar intake (+1.4%E) as well as density of calcium (+18 mg/MJ). Our study proves the impact of lunch on daily dietary quality and yields valuable insights on the development of food and meal-based dietary guidelines. Copyright © 2012 S. Karger AG, Basel.

    Diets based either on casein or soy products and containing about 25 ppm iron were fed to weanling rats for 13 days. Rats were fasted overnight and fed a 59 Fe-radiolabeled casein test meal the morning of day 14. On day 21 less 59 Fe was retained by rats fed various diets based on selected soy products than by rats fed the casein-based diet. A similar adverse effect of diet components on 59 Fe retention from a casein test meal was observed for lactalbumin and for psyllium husk. No adverse effect of diet on 59 Fe retention was observed for the fiber of soy cotyledons or for rapeseed protein concentrate. For a commercial soy protein isolated (SPI) fed throughout the 21-day experiment, the adverse effect of diet on 59 Fe retention was observed to the sum of the effect of dietary SPI previous to the 59 Fe-radiolabeled casein test meal fed on day 14 and the effect of dietary SPI subsequent to the casein test meal. An effect of dietary soy products on 59 Fe retention from a casein test meal was not observed with diets containing higher iron levels (83 ppm) or when diets were fed for a longer period prior to the test meal (56 days). The present work shows that in some circumstances the concept of iron bioavailability must be expanded to include not only the influence of meal composition, but also the influence of diet previous to and subsequent to a meal

    Full Text Available Três ensaios biológicos foram realizados com o objetivo de determinar o conteúdo de energia metabolizável e do coeficientes de digestibilidade do extrato etéreo da soja integral processada por diferentes métodos (extrusão e tostagem e do farelo de soja reconstituído com óleo. No primeiro e segundo ensaios, foram utilizadas a metodologia tradicional de coleta total de excretas, utilizando pintos no primeiro ensaio e galos no segundo. No terceiro ensaio, empregou-se a metodologia de alimentação forçada (Sibbald, 1976 com galos adultos. De acordo com os resultados obtidos, as sojas testadas apresentaram composições bromatológicas semelhantes. Os processamentos usados para a soja integral conferiram diferenças na digestibilidade dos nutrientes da soja e os coeficientes de digestibilidade do extrato etéreo obtidos para a soja extrusada e para o farelo de soja com adição de óleo foram superiores aos obtidos para soja tostada pelo vapor. Os valores de energia metabolizável obtidos para a soja extrusada foram superiores aos encontrados para a soja tostada pelo vapor e para o farelo de soja com adição de óleo, que foram semelhantes entre si.Three-assay birds were conducted to evaluate the contents of metabolizable energy and ether extract digestibility of processed full-fat soybeans by extrusion, by toast and of the soybean meal plus oil. Two assays were carried out by using the traditional total excreta collection by chicks and by rooster, and the other assay was developed by using the force-feeding adult rooster method (Sibbald, 1976. The results showed that the feed composition of the soybean-tested were similar. The different processing caused differences on digestibility of the nutrients of the soybeans tested and the value of coefficients of the nutrients in extruded soybean and soybean meal plus oil were higher than that heated soybean. The value of metabolizable energy was superior in extruded soybean.

    Full Text Available The aim of this study was to compare the effects of two levels of crude protein using poultry by-product meals (PBPM fed during late gestation on the performance, blood metabolites, and colostrum composition of Holstein dairy cows. Sixteen multiparous cows 26±6 d before expected calving were assigned randomly to two treatments containing 1 14% and 2 16% crude protein. The cow’s BCS was 3.56 ± 0.5 on average, at the beginning of the trial. Yields of milk, protein, lactose, fat, and SNF were not affected by prepartum dietary CP level. Colostrum composition (fat, CP and Total solids, blood metabolites (Ca, Glucose, Total protein, Albumin, Globulin and Urea N, and metabolic diseases incidence were not influenced by prepartum dietary CP level. There was no significant difference between treatments in body weight and BCS changes. As expected, blood urea N before calving was higher in the cows fed 16% CP diets. Serum cholesterol during prepartum and postpartum periods was significantly decreased as the CP increased in the diet. In general, although postpartum glucose level increased in cows which received 16% CP in the diet, it seems that no other obvious advantages over feeding the 14% CP diet are apparent. So feeding this last diet is recommended to close up cows.

  19. Effect of corn- and soybean hull-based creep feed and backgrounding diets on lifelong performance and carcass traits of calves from pasture and rangeland conditions

    Science.gov (United States)

    Three separate studies were conducted to investigate the life-long effect of creep feeding, creep feeding energy source (soybean hulls, SC, or corn, CC) and interactive effects of creep feed with backgrounding dietary energy source (soybean hulls, SBR, or corn, CBR) on calf growth performance, carca...

    Full Text Available The development of easy-to-use and accurate methods to assess the intake of energy, foods and nutrients in pre-school children is needed. KidMeal-Q is an online food frequency questionnaire developed for the LifeGene prospective cohort study in Sweden. The aims of this study were to compare: (i energy intake (EI obtained using KidMeal-Q to total energy expenditure (TEE measured via doubly labelled water and (ii the intake of certain foods measured using KidMeal-Q to intakes acquired by means of 24 h dietary recalls in 38 children aged 5.5 years. The mean EI calculated using KidMeal-Q was statistically different (p < 0.001 from TEE (4670 ± 1430 kJ/24 h and 6070 ± 690 kJ/24 h, respectively. Significant correlations were observed for vegetables, fruit juice and candy between KidMeal-Q and 24 h dietary recalls. Only sweetened beverage consumption was significantly different in mean intake (p < 0.001, as measured by KidMeal-Q and 24 h dietary recalls. In conclusion, KidMeal-Q had a relatively short answering time and comparative validity to other food frequency questionnaires. However, its accuracy needs to be improved before it can be used in studies in pre-school children.
