  1. GOAT MILK PRODUCTION UNDER ORGANIC FARMING STANDARS

    Gerold Hartmut Rahmann

    2009-02-01

    Full Text Available Organic farming has emerged from its niche. This holds true for organic goat milk, yoghurt and cheese as well. Particularly in the EU many dairy goat farms have converted or want to convert towards organic farming to profit from the positive image and the good prices for milk (+100% in Western Europe and Alpine regions. High performance dairy goats demand excellent feedstuffs, a sound environment and top management. It was not clear how organic farming can fulfil these demands. The restrictive factors influencing the productivity of the animals in organic farming are as follows: limited concentrate feeding (

  2. The Production of Goat Milk under Organic Requests

    2011-10-01

    Full Text Available Organic farming has turned into a very important subject who consists in a food production label and it has become very popular. That is because, especially in the EU the majority of the dairy goat farms want or have already applied the organic farming in order to benefit not only from the good price of milk but also from the given positive image. The main issue of this study is the high production of goat milk using organic farming under specific regulations. Therefore, the organic farming is based on a safe environment, 100% organic feedstuffs, healthy animals (by prevention of diseases, natural mating, reduced stress in animal rearing, modern stables and milking equipment. A few feeding rations were established to improve the quantity and quality of goat milk.

    Goat production concentrated in developing countries (tropics, dry areas), contributes largely to the livelihoods of low and medium income farmers. Farming systems in these areas have evolved to cope with the formidable constraints imposed by harsh natural and economic conditions by adapting integrated crop/livestock production strategies. In Asia, Africa and Latin America, due to its almost exclusive extensive nature, goat production relies mainly on grazing on communal lands that hardly provide the minimum nutrient requirements due to overstocking and degradation. While some of these production systems are becoming semi-intensive, appropriate breeding strategies should be designed to promote conservation and improvement of their unique attributes, such as adaptability, water use efficiency and suitability under harsh climatic conditions. In Europe, dairy goat production is more common around the Mediterranean basin, where it is important from an economic, environmental and sociological perspective to the Mediterranean countries: Spain, France, Italy and Greece. Europe owns only 5.1 % of the world's dairy goat herds, but produces 15.6 % of the world's goat milk; this is the only continent where goat milk has such an economic importance and organization. In developing countries the dairy goat sector requires a systemic approach, whereby nutrition, animal health, breeding, know-how, inputs and technologies must be assembled. This would allow the optimization of natural and local resources and would promote the transition from a risk reduction strategy towards an increased productivity strategy. Such an increase would privilege production efficiency based on clean, green and ethical practices for responsible innovation.

    This study evaluated patterns and species composition of parasitic infections detected over a 1-year period at an organic goat farm. As a result of coprological examination, the overall prevalence of observed strongylids (99%), coccidia of the genus Eimeria (98%), and Muellerius capillaris lungworms (93%) was calculated. The most prevalent strongylids recovered from incubated fecal samples were Haemonchus contortus (42%), genera Trichostrongylus (23%), Oesophagostomum columbianum (13%), and Teladorsagia circumcincta (11%). A maximum intensity of coccidia infection 5150 oocysts per gram, strongylids infection 9900 eggs per gram and lungworm infection 867.26 larvae per gram were detected. The various effects (including environment, host, and parasites) on milk yield, lactose, protein, and fat were evaluated using generalized linear mixed models. Milk yield (P goat. With the intensity of infection detected in our study, only protein content was affected (P goat itself can substantially decrease protein content but has much less of an effect on fat, milk yield, and lactose. Based on our results, we can conclude that a low intensity of parasitic infections does not significantly affect milk yield and the qualitative parameters of milk.

    Full Text Available Aim: This study was carried out to investigate the effect of incorporation of different level of walnut cake in concentrate mixture on in vitro dry matter degradation in order to determine its level of supplementation in ruminant ration. Materials and Methods: Walnut cake was used @ 0, 10, 15, 20, 25 and 30% level to formulate an iso-nitrogenous concentrate mixtures and designated as T1, T2, T3, T4, T5 and T6 respectively. The different formulae of concentrate mixtures were used for in vitro gas production studies using goat rumen liquor with wheat straw in 40:60 ratio. Proximate composition, fiber fractionation and calcium and phosphrous content of walnut cake were estimated. Result: The per cent IVDMD value of T1 and T2 diets was 68.42 ± 1.20 and 67.25 ± 1.37 respectively which was found highest (P<0.05 T3, T4, T5 and T6. Similar trend was also found for TDOM and MBP. Inclusion of walnut cake at 10% level in the concentrate mixture does not affect in vitro dry matter digestibility (IVDMD, truly degradable organic matter (TDOM, mg/200 mg DM, total gas production, microbial biomass production (MBP and efficiency of microbial biomass production (EMP. Conclusion: It is concluded that walnut cake incorporation up to 10% level in the iso -nitrogenous concentrate mixture has no any negative effect on in vitro digestibility of dry matter (DM, TDOM, MBP, EMP and total gas production in goat.

  11. An economic analysis of communal goat production.

    The economic impact of different extension messages used was calculated using enterprise budgeting (gross margin analysis). Input data were gleaned from the literature, from participatory appraisals, as well as a field study, spanning 12 months, of small-scale communal goat farming systems in Jericho in the Odi District of North West Province. The number of offspring weaned per annum, as a proportion of does owned, was selected as the desired output for analysis. This study has shown that small-scale communal goat farmers are not adopting or implementing extension messages to improve production capacity. In South Africa the majority of goats are slaughtered in the informal sector. If the informal sector is to be persuaded to market goats commercially through formal channels, then knowledge of the economics of goat farming on communal lands should be provided. The economic aspects of extension messages are probably an important factor in determining acceptance and sustainability yet appear to be seldom investigated. The probable reason for lack of adoption of standard extension messages, which promote improved nutrition, parasite control, vaccination and treatment of goats, was economic. In other words, the so-called 'poor management practices' used by communal farmers appeared to be economically more profitable than the 'good management practices' suggested to increase production. The price of communal goats was not related to their mass. A higher level of inputs would probably have resulted in a heavier kid, however it was established that this would not have influenced the price received as a majority of the goats were slaughtered for ritual purposes where age, colour and sex were more important to the purchaser than body mass. It is standard practice in commercial farming systems to evaluate the economic benefits of all management practices before they are implemented.

    Full Text Available A study to evaluate the productivity of Boer and Kacang goats dam was carried out for 2 years atResearch Institute for Goat Production, Sungei Putih-North Sumatera. The materials used were goatsowned by the institute. The parameters observed were total birth and weaning weights of kid, litter size,parity of dam, pre-weaning mortality and kidding interval. The rate of reproduction and productivity ofthe dam were estimated using Amir and Knipscheer methods and were statistically analyzed usingGeneral Linear Model. The results showed that the total birth and weaning weight of Boer goats werehigher (P<0.05 than that of Kacang goats, while litter size of Boer goats were higher (P<0.05 than thatof Kacang goats. The pre-weaning mortality of Boer goat 15.1 ± 6.02% was lower than that ofKacang. The kidding interval of Boer goats was higher (P<0.05 than that of Kacang. Parity of dam hadsignificant effect on all production traits (P<0.05 except for pre-weaning mortality. Dam reproductionrate of Boer (1.81 was higher than that of Kacang (1.78, while productivity of Boer goat (37.12kg/head/year was higher than that of Kacang (18.12. It can be concluded that the reproductivity ofBoer and Kacang goats were similar, however the productivity of Boer goat had better than Kacang.

  16. Communal goat production in Southern Africa: a review.

    Rumosa Gwaze, F; Chimonyo, M; Dzama, K

    2009-10-01

    Despite the fact that about 64% of goats in sub-Saharan Africa (SSA) are located in rural arid (38%) and semi-arid (26%) agro-ecological zones and that more than 90% of goats in these zones are indigenous, information on indigenous breeds is inadequate. This paper reviews the social and economic importance of goats to the communal farmer and assesses the potential of using goats in rural development in Southern Africa. Farmers in Southern Africa largely use the village goat management system. There are various goat breeds in Southern Africa, of which the Mashona, Matabele, Tswana, Nguni and the Landim are the dominant ones. It is, however, not clear if these breeds are distinct. Major constraints to goat production include high disease and parasite prevalence, low levels of management, limited forage availability and poor marketing management. Potential research areas that are required to ensure that goats are vehicles for rural development include evaluation of constraints to goat production, assessing the contribution of goats to household economies and food securities throughout the year, genetic and phenotypic characterisation of the indigenous breeds to identify appropriate strains and sustainable methods of goat improvement through either selection or crossbreeding.

  17. Differences in sheep and goats milk fatty acid profile between conventional and organic farming systems.

    Tsiplakou, Eleni; Kotrotsios, Vaios; Hadjigeorgiou, Ioannis; Zervas, George

    2010-08-01

    The objective of this study was to investigate whether there is a difference in chemical composition and particularly in fatty acid (FA) profile, with emphasis on cis-9, trans-11 CLA, of milk obtained from conventional and organic dairy sheep and goats farms under the farming conditions practiced in Greece. Four dairy sheep and four dairy goat farms, representing common conventional production systems and another four dairy sheep and four dairy goat farms, organically certified, representing organic production and feeding systems were selected from all over Greece. One hundred and sixty two individual milk samples were collected from those farms in January-February 2009, about three months after parturition. The milk samples were analyzed for their main chemical constituents and their FA profile. The results showed that the production system affected milk chemical composition: in particular fat content was lower in the organic sheep and goats milk compared with the corresponding conventional. Milk from organic sheep had higher content in MUFA, PUFA, alpha-LNA, cis-9, trans-11 CLA, and omega-3 FA, whereas in milk from organic goats alpha-LNA and omega-3 FA content was higher than that in conventional one. These differences are, mainly, attributed to different feeding practices used by the two production systems. The results of this study show that the organic milk produced under the farming conditions practiced in Greece has higher nutritional value, due to its FA profile, compared with the respective conventional milk.

    This study evaluated the effects of replacing ground corn with buriti oil ( L.) on feed intake and digestibility and on the production, composition, fatty acid profile and sensory characteristics of goat milk. A double Latin square (4 × 4) was used; eight goats were distributed in a completely randomized design. The square comprised four periods and four buriti oil concentration (0.00; 1.50; 3.00 and 4.50% of total DM) replacing corn. Intakes of DM, CP, NDF, ADF, non-fibrous carboydrates (NFC) and TDN were not affected by the replacement of corn with oil in the diet. However, lipids intake was increased ( goats with 4.50% oil inclusion, as total DM. DM and CP digestibility were similar between the buriti oil concentrations. However, lipid digestibility increased linearly ( = 0.01) and may have contributed to a quadratic reduction in NDF digestibility ( = 0.01) and a linear reduction of NFC ( = 0.04) with buriti oil content in the goat feed. Goat milk production, corrected production and chemical composition were not influenced by the concentration of buriti oil replacement; however, milk fat concentration ( = 0.04) and feed efficiency ( goat's diet. In contrast, the fatty acids C18:0 ( goats that were fed with buriti oil. However, CLA ( 0.05) by the replacement of corn with buriti oil in the goats' diet. It is recommended to replace corn with buriti oil in goat feed by up to 4.5% of total DM, resulting in improved feed efficiency and milk fat without affecting production; this recommendation satisfies the minimum requirements of the industry and preserves the organoleptic characteristics of the milk and its acceptability for human consumption. In addition, buriti oil replacing ground corn by up to 4.5% DM in the diet of lactating goats decrease medium-chain SFA which are hypercholesterolemic and increase the concentrations of the C18:19, CLA and DFA in goat milk fat, helping to protect against cardiovascular disease.

    2005-06-01

    Full Text Available In order to determine the safety of milk produced by smallholder dairy goat farms, a farm-based research study was conducted on commercial dairy goat farms to compare the microbiological quality of milk produced using 3 different types of dairy goat production systems (intensive, semi-intensive and extensive. A survey of dairy goat farms in and around Pretoria carried out by means of a questionnaire revealed that most of the smallholder dairy goat farms surveyed used an extensive type of production system. The method of milking varied with the type of production system, i.e. machine milking; bucket system machine milking and hand-milking, respectively. Udder half milk samples (n=270 were analysed, of which 31.1 % were infected with bacteria. The lowest intra-mammary infection was found amongst goats in the herd under the extensive system (13.3 %, compared with 43.3 % and 36.7 % infection rates under the intensive and semi-intensive production systems, respectively. Staphylococcus intermedius (coagulase positive, Staphylococcus epidermidis and Staphylococcus simulans (both coagulase negative, were the most common cause of intramammary infection with a prevalence of 85.7 % of the infected udder halves. The remaining 14.3 % of the infection was due to Staphylococcus aureus. Bacteriology of bulk milk samples on the other hand, showed that raw milk obtained by the bucket system milking machine had the lowest total bacterial count (16 450 colony forming units (CFU/mℓ compared to that by pipeline milking machine (36 300 CFU/mℓ or handmilking (48 000 CFU/mℓ. No significant relationship was found between the somatic cell counts (SCC and presence of bacterial infection in goat milk. In comparison with the herds under the other 2 production systems, it was shown that dairy goat farming under the extensive production system, where hand-milking was used, can be adequate for the production of safe raw goat milk.

  10. Carbon footprint of dairy goat milk production in New Zealand.

    Robertson, Kimberly; Symes, Wymond; Garnham, Malcolm

    2015-07-01

    The aim of this study was to assess the cradle-to-farm gate carbon footprint of indoor and outdoor dairy goat farming systems in New Zealand, identifying hotspots and discussing variability and methodology. Our study was based on the International Organization for Standardization standards for life cycle assessment, although only results for greenhouse gas emissions are presented. Two functional units were included: tonnes of CO2-equivalents (CO2e) per hectare (ha) and kilograms of CO2e per kilogram of fat- and protein-corrected milk (FPCM). The study covered 5 farms, 2 farming systems, and 3yr. Two methods for the calculation of enteric methane emissions were assessed. The Lassey method, as used in the New Zealand greenhouse gas inventory, provided a more robust estimate of emissions from enteric fermentation and was used in the final calculations. The alternative dry matter intake method was shown to overestimate emissions due to use of anecdotal assumptions around actual consumption of feed. Economic allocation was applied to milk and co-products. Scenario analysis was performed on the allocation method, nitrogen content of manure, manure management, and supplementary feed choice. The average carbon footprint for the indoor farms (n=3) was 11.05 t of CO2e/ha and 0.81kg of CO2e/kg of FPCM. For the outdoor farms (n=2), the average was 5.38 t of CO2e/ha and 1.03kg of CO2e/kg of FPCM. The average for all 5 farms was 8.78 t of CO2e/ha and 0.90kg of CO2e/kg of FPCM. The results showed relatively high variability due to differences in management practices between farms. The 5 farms covered 10% of the total dairy goat farms but may not be representative of an average farm. Methane from enteric fermentation was a major emission source. The use of supplementary feed was highly variable but an important contributor to the carbon footprint. Nitrous oxide can contribute up to 18% of emissions. Indoor goat farming systems produced milk with a significantly higher carbon

    1997-01-01

    The paper contains results of determinations of protein, fat, carbohydrates, water and minerals (Ca, P, Fe, Mn, Cu, Zn, Na, K) in 12 goat milk products. The nutrient components were determined by general approved analytical methods. Minerals like Ca, Fe, Mn, Cu, Zn, Na and K were determined by the flame ASA method. Phosphorus was determined as phosphates by colorimetric method with ammonium molybdate. Mean percentage content of protein, fat, carbohydrates and water were: 9.7-25.7; 1.4-33.5; 2.2-70.2; and 3.0-77.4 respectively. The content of minerals according to the products of goat milk were as follow: 86-1113 mg% Ca; 96-846 mg% P; 0.2-2.4 mg% Fe; 6-148 mg% Mg; 0.002-0.284 mg% Mn; 0.071-0.754 mg% Cu; 1.1-3.9 mg% Zn; 63-1281 mg% K and 27-407 mg% Na. The levels of nutrients and mineral composition of the examined goat milk products were similar to that of the cows milk products.

    Developmental competence of oocytes from prepubertal females is lower than those from adult females. Oocyte development competence is positively related to follicular diameter. Most of the follicles of prepubertal goat ovaries are smaller than 3 mm. The aim of this study was to compare oocytes of two follicle sizes (goats with oocytes from adult goats in relation to their in vitro production and quality of blastocysts. Oocytes from prepubertal goats were obtained from slaughterhouse ovaries and selected according to the follicle diameter whereas oocytes from adult goats were recovered in vivo by LOPU technique without prior selection of follicle size. COCs were IVM for 27 h, IVF at the conventional conditions with fresh semen and presumptive zygotes were cultured in SOF medium for 8 days. Blastocysts obtained were vitrified and after warming their blastocoele re-expansion and the ploidy by FISH technique were assessed. We found significant differences between blastocysts yield of oocytes recovered from follicles smaller than 3 mm of prepubertal goats compared to those from adult goats (5.45% vs 20. 83%, respectively) however, these differences disappear if oocytes were recovered form large follicles (18.07%). A total of 28 blastocysts were analysed and 96.43% showed mixoploidy. Age did not affect the number of embryos with abnormal ploidy or blastocyst re-expansion after warming. Furthermore, the percentage of diploid blastomeres per embryo was similar in the 3 groups studied, adult, prepubertal from follicles ≥ 3 mm and goats 45 days old were not different to the blastocysts produced from adult goats, both in terms of quantity and quality.

  14. Niclosamide residues in milk and organs of lactating goats

    El Hindi, A.M.; Sidra, M.S.

    1986-01-01

    14 C-Niclosamide was administered to two groups of lactating goats at levels of 2ppm for five consecutive days and 10ppm as a single dose. Residues of the molluscicide in milk, if at all present, did not exceed 0.001 ppm at any time. About 50% of the administered activity was excreted in faeces, while 30% excreted through urine in animals surviving 6 days after withdrawal. The unchanged molluscicide is present only in relatively trace amounts. The highest residues in organs were found in the liver of both groups (0.01-0.04 ppm). From the results it could be concluded that absorbed niclosamide is completely metabolised and rapidly eliminated through urine, leaving little or no residues of the unchanged molluscicide. Little or no residues were detected in lean muscles and milk which are consumed by humans. There is no preferential deposition of the molluscicide or its metabolites in fat

    The Creole goat is a local meat breed well adapted to the tropical environment of Guadeloupe, a French island in the Caribbean. A survey of 47 goat farmers was conducted in May 2008 to describe the Guadeloupean goat farming systems. It was the preliminary step for the implementation of a breeding programme for Creole goats. Farmers had 31 does on average. A small number (4%) kept only Creole goats. Most of them (62%) had a mixed herd of Creole and crossbreds. One-third of them (34%) reared only crossbred goats. Farmers appreciate the rusticity and resistance of the Creole goat but consider its growth as too slow. The most desired traits for goat selection were conformation and growth for males (77% of the answers). These traits were also important for females (30% of the answers). Maternal qualities were also frequently cited (maternal behaviour 23%, reproduction 20% and milk production 17%). Disease resistance was not seen as an important trait (10% and 7% of the answers for bucks and does, respectively). A typology constituted of five groups of farmers was also created. Farmers of three groups were retained to participate at a selection programme. They kept Creole goats and have expressed a strong willingness to join a selection programme. The results of the survey suggest that a breeding programme should mostly focus on the Creole goat as a maternal breed. Real consideration should be given to disease resistance. The Creole goat has indeed a key role to play in the sustainability of local farming systems.

    2016-02-01

    The aim of this study was to identify the differences between the main macro and micronutrients including proteins, fat, minerals and vitamins in cow and goat dehydrated fermented milks. Fermented goat milk had higher protein and lower ash content. All amino acids (except for Ala), were higher in fermented goat milk than in fermented cow milk. Except for the values of C11:0, C13:0, C16:0, C18:0, C20:5, C22:5 and the total quantity of saturated and monounsaturated fatty acids, all the other fatty acid studied were significantly different in both fermented milks. Ca, Mg, Zn, Fe, Cu and Se were higher in fermented goat milk. Fermented goat milk had lower amounts of folic acid, vitamin E and C, and higher values of vitamin A, D3, B6 and B12. The current study demonstrates the better nutritional characteristics of fermented goat milk, suggesting a potential role of this dairy product as a high nutritional value food.

  1. A survey analysis of indigenous goat production in communal farming systems of Botswana.

    Monau, P I; Visser, C; Nsoso, S J; Van Marle-Köster, E

    2017-08-01

    A total of 153 communal farmers in four agro-ecological regions of Botswana were interviewed using a structured questionnaire. The aims of the survey were to characterise existing communal goat production systems, evaluate the importance of goats to farmers and identify breeding practices and constraints encountered in goat production in Botswana. Data was collected on socio-economic parameters, general and breeding management practices and major constraints limiting goat production in Botswana. All respondents were small-scale communal farmers with 63% respondents practising mixed crop-livestock farming and 37% keeping livestock as their primary activity. The majority (33%) of respondents were older than 60 years. Over 80% of the farmers kept goats for cash required for tuition, school uniforms and household commodities as well as re-stocking of animals. Most farmers (62%) kept indigenous crossed genotypes. Generally, uncontrolled mating was practised with the majority of farmers (41%) using on-farm reared bucks for more than two years of breeding and communal bucks (36%) as an alternative. The major constraints limiting goat productivity in communal areas included uncontrolled breeding, predators, theft and diseases. Issues raised by farmers should be considered in designing and implementing effective breeding programs for goats to improve their overall productivity and contribution to poverty alleviation in these communities.

  2. Productive and Reproductive Performances of Female Etawah Crossbred Goats in Indonesia

    I Ketut Sutama

    2009-03-01

    Full Text Available Although Etawah Crossbred (PE goat is considered to be dual purpose (meat and milk goat, it is mainly raised for meat production. Since early 1990, there has been a growing interest of the farmer in some places to raise PE goat for milk production without sacrificing its role to produce kids for meat. The average birth weight of PE kids varied widely (2.8 – 5 kg, resulted in a high variation in weaning weight (9 – 14 kg. A high pre-weaning mortality of 10 – 50% was a major source of lost in goat production in Indonesia, partly due to low birth weight and/or miss mothering ability. Young female PE goat reached puberty at 8 – 12 months of age and at body weight of about 18 – 22 kg or about 53 – 60% of mature body weight. Gestation length varied between 142 – 156 days, and first post partum estrous occurred at 3 – 5 months after parturition took place, resulted in 8 – 10 months of kidding intervals. Lactation period lasted for 5 – 8 months with total milk yield of 177 – 203 kg/lactation (average 0.85 kg/day. Although milk yield of PE goat was not as high as milk yield of some other dairy goats, the ability of PE goat to cope with harsh local environment, particularly climate and feed conditions, was an advantage. Therefore, raising PE goat would still be an important part of farmer activities in the rural areas in Indonesia.

In this study, stockmanship competence (SC is defined as the capacity of the stockperson to ensure the welfare of his animals by providing his animals’ needs. The study was conducted to evaluate the SC of backyard goat raisers and examine its relationship to goat productivity and economic profitability. There were 101 respondents for this study who have all undertaken farmer livestock school on integrated goat management (FLS-IGM. Interview was conducted in Region I, Philippines on September 3 to 30, 2012 and March 4 to 17, 2013. Data on SC, goat productivity and farmer’s income were gathered. Questions regarding SC were formulated based on the Philippine Recommendations for Goat Production and from other scientific literature. Housing, feeding, breeding and health and husbandry management were the indicators used in computing stockmanship competence index score (SCIS. Pearson correlation using Statistical Package for Social Science (SPSS was carried out to analyse the relationship between SCIS, productivity and income. Based from the results of the study, a majority of the respondents raised native and upgraded goats. The computed mean SCIS before and after undergoing FLS-IGM were 38.52% and 75.81% respectively, a percentage difference of 65.23%. Both index scores resulted in significant differences in productivity and income. The median mature weight and mortality rate of goats before FLS-IGM was 14 kg and 30% respectively. After FLS-IGM, median mature weight was 19 kg and mortality rate decreased from 30% to 11.11%. Likewise, fewer goat diseases were observed by farmers who were able to undergo FLS-IGM. With regard to income, there was a 127.34% difference on the median net income derived by farmers. Result implies that improved SC could lead not only to increased productivity and income of backyard goat

  6. Influence of farming system and production purpose on the morpho structure of Spanish goat breeds

    Gonzalez-Martinez, A.; Herrera, M.; Luque, M.; Rodero, E.

    2014-06-01

    The aim of this study was to examine the possible influence of farming systems, based on the morpho structure of 1,571 female goats drawn from 40 flocks containing seven Spanish breeds (Blanca Andaluza, Blanca Celtiberica, Negra Serrana, Pirenaica, Payoya, Murciano-Granadina and Malaguena) raised under four different farming systems. Analysis of morphometric variables showed that the morphostructure of native Spanish goat breeds was linked to the farming system used and thus to the production purpose. The morphostructure of grazing breeds may be more influenced by natural selection within the physical environment and less by human selection. That of stall-fed breeds, by contrast, reflects intense artificial selection aimed at achieving a highly-productive dairy type. For this reason, morphological evaluation systems used in breeding programmes for meat or dual-purpose goat breeds farmed extensively or semiextensively should be specific, and should reflect the influence of the environment in which these goats are farmed.

  7. Development and application of a crossbreeding simulation model for goat production systems in tropical regions.

    Tsukahara, Y; Oishi, K; Hirooka, H

    2011-12-01

    A deterministic simulation model was developed to estimate biological production efficiency and to evaluate goat crossbreeding systems under tropical conditions. The model involves 5 production systems: pure indigenous, first filial generations (F1), backcross (BC), composite breeds of F1 (CMP(F1)), and BC (CMP(BC)). The model first simulates growth, reproduction, lactation, and energy intakes of a doe and a kid on a 1-d time step at the individual level and thereafter the outputs are integrated into the herd dynamics program. The ability of the model to simulate individual performances was tested under a base situation. The simulation results represented daily BW changes, ME requirements, and milk yield and the estimates were within the range of published data. Two conventional goat production scenarios (an intensive milk production scenario and an integrated goat and oil palm production scenario) in Malaysia were examined. The simulation results of the intensive milk production scenario showed the greater production efficiency of the CMP(BC) and CMP(F1) systems and decreased production efficiency of the F1 and BC systems. The results of the integrated goat and oil palm production scenario showed that the production efficiency and stocking rate were greater for the indigenous goats than for the crossbreeding systems.

    2007-01-01

    Full Text Available The purpose of the work is to study the efficiency of the diet therapy against atopic dermatitis by means of the goat's milk based products among children at different age. The researchers observed 188 children aged between 3 months and 18 years, suffering from atopic dermatitis aggravated by the mycotic infection. Patients of the main group (102 children under 3 received goat's milk based products within the hypo allergic diet — «Nanny» and «Nanny — Zolotaya Kozochka» adapted milk formulas, while children over 3 received «Amal Tea» instant goat's milk. The research findings have showed that the introduction of the goat's milk based products into the food ration leads not only to the positive short term results — achievement of the clinical remission on 12th–20th day from the moment the therapy starts, but also to the positive long term effect — remission extension, reduction of the disease recurrences, reduction of the general IgE level in blood serum and offending IgE allergens to the cow milk proteins and casein. Thus, the replacement of the cow milk based products within the ration of patients for «Nanny» and «Nanny — Zolotaya Kozochka» adapted milk formulas and «Amal Tea» instant goat's milk allows for optimization of the atopic dermatitis diet therapy among children at different age.Key words: atopic dermatitis, diet therapy, goat's milk.

    Fermentative capacity among ruminants can differ depending on the type of ruminant species and the substrate fermented. The aim was to compare in vitro cow and goat rumen inocula in terms of methane (CH 4 ) and gas production (GP), fermentation kinetics and 72 h volatile fatty acids (VFA) production using the browse species Acacia etbaica, Capparis tomentosa, Dichrostachys cinerea, Rhus natalensis, freeze-dried maize silage and grass silage, and a concentrate as substrates. Total GP, CH 4 and VFA were higher (P ≤ 0.008) in goat inoculum than cows across substrates. The half-time for asymptotic GP was lower (P goats compared to cows. Methane production and as a percentage of total GP was higher (P goats compared to cows. Goat inoculum showed higher fermentative activity with a concomitant higher CH 4 production compared to cows. This difference highlights the ability of goats to better utilise browse species and other roughage types. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Dairy small ruminants account for approximately 21% of all sheep and goats in the world, produce around 3.5% of the world's milk, and are mainly located in subtropical-temperate areas of Asia, Europe, and Africa. Dairy sheep are concentrated around the Mediterranean and Black Sea regions, where their dairy products are typical ingredients of the human diet. Dairy goats are concentrated in low-income, food-deficit countries of the Indian subcontinent, where their products are a key food source, but are also present in high-income, technologically developed countries. This review evaluates the status of the dairy sheep and goat sectors in the world, with special focus on the commercially and technically developed industries in France, Greece, Italy, and Spain (FGIS). Dairy small ruminants account for a minor part of the total agricultural output in France, Italy, and Spain (0.9 to 1.8%) and a larger part in Greece (8.8%). In FGIS, the dairy sheep industry is based on local breeds and crossbreeds raised under semi-intensive and intensive systems and is concentrated in a few regions in these countries. Average flock size varies from small to medium (140 to 333 ewes/farm), and milk yield from low to medium (85 to 216 L/ewe), showing substantial room for improvement. Most sheep milk is sold to industries and processed into traditional cheese types, many of which are Protected Denomination of Origin (PDO) cheeses for gourmet and export markets (e.g., Pecorino, Manchego, and Roquefort). By comparing break-even milk price among FGIS countries, we observed the following: (1) most Greek and French dairy sheep farms were unprofitable, with the exception of the intensive Chios farms of Greece; (2) milk price was aligned with cost of production in Italy; and (3) profitable farms coexisted with unprofitable farms in Spain. In FGIS, dairy goat production is based on local breeds raised under more extensive systems than sheep. Compared with sheep, average dairy goat herds are

    Goat milk yogurts were manufactured with the fortification of 2% (wt/vol) skim goat milk powder (SGMP), sodium caseinate (NaCn), whey protein concentrate (WPC), whey protein isolate (WPI), or yogurt texture improver (YTI). Yogurts were characterized based on compositional, microbiological, and textural properties; volatile flavor components (with gas chromatography); and sensory analyses during storage (21d at 5 °C). Compared with goat milk yogurt made by using SGMP, the other goat milk yogurt variants had higher protein content and lower acidity values. Goat milk yogurts with NaCn and WPC, in particular, had better physical characteristics. Using WPI caused the hardest structure in yogurt, leading to higher syneresis values. Acetaldehyde and ethanol formation increased with the incorporation of WPI, WPC, or YTI to yogurt milk. The tyrosine value especially was higher in the samples with NaCn and YTI than in the samples with WPC and WPI. Counts of Streptococcus thermophilus were higher than the counts of Lactobacillus delbrueckii ssp. bulgaricus, possibly due to a stimulatory effect of milk protein-based ingredients other than SGMP on the growth of S. thermophilus. Yogurt with NaCn was the best accepted among the yogurts. For the parameters used, milk protein-based products such as NaCn or WPC have promising features as suitable ingredients for goat milk yogurt manufacture.

    2018-01-01

    Aim: Assessment of the status of subclinical mastitis (SCM) in Jamunapari and Barbari goats in Indian organized farms, the involvement of bacterial pathogens and their sensitivity to antibiotics. Materials and Methods: A total of 181 composite milk samples were aseptically collected from the apparently healthy Barbari (n=95) and Jamunapari (n=86) goats. The California mastitis test (CMT) and somatic cell count (SCC) were used to diagnose SCM. The milk samples with CMT scores of 0 and +1 were considered as negative, while the samples with the score of +2 or +3 were taken as positive, and further, the positive samples were used for the bacteriological examination. An antibiotic sensitivity test was performed by disk diffusion method using seven commercially available antibiotic discs. Results: All the samples having CMT score of +2 or +3 demonstrated SCC more than 1 million. Overall, the prevalence of SCM in the goats was assessed as 19.89% (36/181). The prevalence of SCM in Barbari and Jamunapari goats was found as 24.21% (23/95) and 15.12% (13/86), respectively. Out of 11 isolates of Staphylococci, 9 isolates were identified as coagulase-negative Staphylococci (CNS), whereas 2 isolates were found as Staphylococcus aureus. The identified bacterial isolates (n=30) did not show antibiotic resistance. Conclusion: The current investigation showed the considerable prevalence of SCM among Jamunapari and Barbari goats which may have a negative impact on quantity and quality of the milk. CNS was found as the most prevalent cause of SCM in the goats. Negligible antibiotic resistance was found among the identified udder pathogens. PMID:29479152

    Full Text Available Forty-five wether goat kids (BW of 21.76 + 0.76 were randomly assigned to one of three production systems for 14 weeks to evaluate intake, digestibility and goat performance. Production systems were: 1 feedlot (FL, housed in individual pens and fed 40% protein pellets, 40% soybean hulls and 20% bermudagrass hay; 2 grazing continuously on 1 hectare bahiagrass pasture (BP supplemented daily with 150 g of protein pellets/hd; and 3 browsing rotationally on 4, 0.5 hectare mimosa (MB supplemented daily with 100 g cracked corn/hd. Body weights were recorded every two weeks. Feed intake and digestibility were measured on eight goats from each treatment groups. Goats were fitted with canvas fecal collection bags, allowed for 3 days of adjustments followed by 5 days of fecal collection. Feces, feed offered, pasture and browse samples were analyzed for acid insoluble ash to determine digestibility and predict intake. Rumen fluid and blood samples were collected to measure volatile fatty acids and blood urea nitrogen (BUN. Total feed and medication costs also were recorded. Goats on FL system gained faster (P 0.10 in butyrate and valerate. However, acetate: propionate was lower (P 0.10 BUN. Numerically, browse system was most cost effective and bahaigrass pasture was most expensive in terms of animal production.

    Full Text Available The main objectives of this study were to assess the influence of environmental (non-genetic factors on kid production traits of Kacang goat under smallholders production system. The study was conducted at the Kacang goat smallholders, located at the centre of Kacang goat in Gundi subdistric, Purwodadi regency, Central Java. The kid production traits evaluated are birth weight, weaning weight, and growth rate till weaning. The environmental factors assessed were: sex (male, female, type of birth (singles, twins, triplets and dam’s parity (1-7. Data were analysed statistically according to the analysis of variance procedure using the General Linear Model (GLM. Least squares analysis revealed that dam’s parity, birth type, and sex of kid were significant sources of variation for birth and weaning weight and pre weaning growth in Kacang kids. The average birth weight, weaning weight and pre weaning growth of males (2.07±0.02 kg; 10.457±0.1 kg; 69.35±0.73 g/d were found to be higher than females (1.95±0.02 kg; 9.15±0.09 kg; 60.73±0.71 g/d. Kid production traits increased with parity, with the largest values at the fourth parity and then slightly decreased thereafter. The average male and female birth weight (2.18+0.03 kg; 2.02+0.03 kg, weaning weight (10.72+0.11 and 9.39+0.13 kg and pre weaning growth (71.63+0.79 and 62.21+0.96 g/d of single kids were heavier than twins, and triplets indicating the influence of the mothering ability of doe.

    The aim of this work was to determine the adaptability of Saanen and ½Saanen × ½Anglo-Nubian (½S½AN) goats bred in tropical climates. The study included 30 goats, 15 Saanen and 15 ½S½AN. The data was collected during the rainy and dry seasons. During the whole experimental period, the environment variables were recorded, as well as rectal temperature (RT), superficial temperature (ST), respiratory rate (RR) and heart rate (HR) and milk production (MP). The adaptability coefficient (AC) was calculated for both genotypes. The averages were evaluated by ANOVA at 5 % probability. There was a genotype and period of year effect, as well as the interaction genotype × period of year. Pearson's simple correlation analysis was then carried out between milk production and physiological and environment variables. There was a statistical difference ( p goats, regardless of the season. MP was greater in the dry season ( p goats. Under the conditions of the present study, it is concluded that the goats were influenced by climatic factors, where the rainy period was more likely to cause thermal stress in the animals.

    Full Text Available The study was conducted to describe sheep and goat production practice in three Agro-ecological Woredas of Gedio zone, southern Ethiopia. A set of semi-structured questionnaire was used to collect information from 120 sheep and goat owners based on single-visit-interviews. 32.6% of them participate in crop production, 56.5% of them involved in both animal and crop production and 5% of them involved in crop production, animal production and off farm activity. Sheep flock in the study sites were significantly different; and were 5.63, 6.97 and 3.4 in Wenago, Dilla and Kochera sites, respectively. Major feed resources were grazing (33.5%. The highest mortality rate occurred in suckling flock (16.24% lambs; 16.3% kids, young flock (9.64% lambs; 13.24% kids and breeding females (ewes 12.06% and does 14.1% in all study sites. Sheep and goat production in the studied areas was constrained by different problems; where the major ones are availability and cost of feeds, limitation of land for the expansion of production and poor extension services. Sheep and goats are very important smallholder producers due to their biological factors such as short generation interval, twinning, have short growth periods and do not require much space.

    In livestock, breed assignment may play a key role in the certification of products linked to specific breeds. Traceability of farm animals and authentication of their products can contribute to improve breed profitability and sustainability of animal productions with significant impact on the rural economy of particular geographic areas and on breed and biodiversity conservation. With the goal of developing a breed genetic traceability system for Girgentana dairy products, the aim of this study was to identify specific microsatellite markers able to discriminate among the most important Sicilian dairy goat breeds, in order to detect possible adulteration in Girgentana dairy products. A total of 20 microsatellite markers were analyzed on 338 individual samples from Girgentana, Maltese, and Derivata di Siria goat breeds. Specific microsatellite markers useful for traceability of dairy products were identified. Eight microsatellite markers showed alleles present at the same time in Maltese and Derivata di Siria and absent in Girgentana and, therefore, they were tested on DNA pools of the three breeds. Considering the electropherograms' results, only FCB20, SRCRSP5, and TGLA122 markers were tested on DNA samples extracted from cheeses of Girgentana goat breed. These three microsatellite markers could be applied in a breed genetic traceability system of Girgentana dairy products in order to detect adulteration due to Maltese and Derivata di Siria goat breeds.

    Full Text Available About 950,000 goats, farmed mostly in hilly and mountainous areas of Albania, contribute about 8% of the country’s total milk production. In order to increase milk production, farmers are currently using crosses of the local goat breed with exotic breeds, mainly the Alpine breed from France. This study examines milk production data of first lactation from 45 goats of the local breed, 82 goats of the Alpine breed and 58 F1 crosses (♂Alpine breed x ♀local breed. The goats were kept on small-scale farms according to the traditional Albanian system. Milking was carried out in the morning and evening. Kids were weaned at 65 days of age after which milking started. Milk yield was recorded twice with a 15-day interval between the two readings. Total milk yield was calculated using the Fleischmann method. The F1 goats produced 37.8 kg more milk than local breed goats although the lactation length (P<0.05 of F1 goats was six days shorter compared to that of local breed goats (P<0.05. Analysis of variance showed a highly significant effect (P<0.01 of the genotype factor on milk production. The average Cappio-Borlino curves of three genotypes indicated that the lactation curves of local breed and F1 crosses were similar. Although the F1 cross goats had 50% of their genomes from a genetically improved breed they were still able to deal with the difficult conditions that characterize the traditional extensive farming systems in Albania. Breeding pure Alpine breed or its crosses with the local goat breed improved milk production in an extensive traditional system.

    2010-04-01

    Full Text Available Aim of this study was to test the effect of raw sunflower seeds on goat milk production. Two farms with different farming systems (intensive and semi-intensive participated to the trial. In each farm about 60 mid-lactation Alpine goats were divided in two groups during spring-summer time. A diet containing 5-6% of sunflower seeds on DM basis was compared with a control diet in a change-over design. In the semi-intensive farm milk yield of goats fed sunflower was 3.46 kg/d compared to 3.58 kg/d of goats fed control diet, whereas in the intensive farm milk yield was 4.60 kg/d vs 4.66 kg/d. Fat content increased significantly from 2.99% to 3.23% only in the intensive farm. The research in the intensive farm investigated also milk and cheese fatty acids composition. Medium and short chain fatty acids (C8-C16 content dropped and long chain fatty acids content increased when sunflower was added. In conclusion raw sunflower seed inclusion in dairy goat diets can be useful, in order to limit the inversion of fat and protein percentages in milk.

    Small ruminants' production contributes to livelihood of pastoral communities, but this faces myriad constraints. This study aimed at identifying challenges facing producers of small ruminants, prioritizing diseases and their control measures and documenting opportunities for improvement. Sixteen focus group discussions with livestock owners and 13 key informant interviews were done in selected areas in Mandera County, Northern Kenya, and both quantitative and qualitative data collected using a questionnaire guide. Occurrences of diseases (27.4%) and drought (25%) were consistently ranked high in all groups. Other production challenges included increased predation of livestock, inadequate delivery of veterinary services, and increased livestock mortalities. Peste des Petit ruminants was ranked high with a median rank of 21.5%, while contagious caprine pleuropneumonia and sheep and goat pox were ranked second and third, respectively. Other diseases included tick-borne diseases, helminthosis, and pneumonia. Vaccination was ranked as the most effective control strategy for infectious diseases. Other control measures included recitation of Quran and cauterization. However, several opportunities exist for support of small ruminants' production: increased budgetary allocation for disease control by government, initiation of projects that enhance livestock production in the region by government and its development partners. These findings are useful for policy makers for disease control and organizations that are working on projects that focuses on enhancement of pastoralists' resilience, while future research could also identify appropriate technologies that reduces these impacts.

    2014-01-01

    Full Text Available The aim of this study was to compare Bacillus cereus growth rates and diarrhoeal enterotoxin production in raw and pasteurized goat, sheep, and cow milk in terms of storage conditions. Milk samples were inoculated with B. cereus (CCM 2010, which produces diarrhoeal enterotoxins. Enterotoxin production was tested by ELISA (Enzyme-Linked Immunosorbent Assay, and the count of B. cereus was determined by the plate method. With raw cow milk, B. cereus growth and enterotoxin production can be completely suppressed; in raw goat and sheep milk, enterotoxin was produced at 22 °C. In pasteurized cow, goat, and sheep milk, the B. cereus count increased under all storage conditions, with more rapid growth being observed at 15 °C (sheep milk and 22 °C (cow and goat milk. Enterotoxin presence was detected at 15 °C and 22 °C, and with pasteurized cow milk also at 8 °C. Our model experiments have determined that B. cereus multiplication and subsequent enterotoxin production depend on storage temperature and milk type.

    The question of whether the adaptability and production performance in goats may be enhanced using a crossbreeding program between bucks of a native and heat-tolerant breed and does of an exotic and dual-purpose breed was approached and examined herein by comparing purebred Aardi and Damascus goats and their crossbred lines (i.e., 1/2 Aardi 1/2 Damascus (½A½D) and 1/4 Aardi 3/4 Damascus (¼A¾D)) reared in a region characterized by dry and hot bioclimatic conditions. Twenty-four male 6-month-old kids randomly segregated into four groups (six replicates/group) were used for the experiment. Climatic, thermo-physiological, biophysiological, metabolic, blood hematological, and biochemical measurements were all determined. The obtained results indicated that such a program was proven to be successful. This conclusion was demonstrated by the findings that crossbred goats (i.e., 1/2A1/2D and 1/4A3/4D) under such bioclimatic conditions were able to show ( P goats as well as manifested ( P goats. Accordingly, these evidences could emphasize that the crossbreeding may enable these animals to display a simultaneous improvement of both traits by the possible benefits that could arise from heterosis and breed complementarity. Researches dealing with this aspect may very well improve our understanding of goat's production and welfare under harsh environmental conditions. Future studies should include an economic analysis of traits that have the potential to impact the overall profitability to a vertically coordinated system.

    Full Text Available The study was carried out with the aim to asses the synchrony of organic matter and crude protein degradation in the rumen of diets selected by range goats through two years. Five esophageal cannulated adult male goats were used to collect extrusa samples during summer (August 9–13 and autumn (November 29 –December 3 of 2006, winter (February 20 – 24, spring (April 29 –May 5, summer (September 10–15 and autumn (December 4–8 of 2007 and winter (February 20 – 25 and spring (May 9 –13 of 2008. Extrusa samples were subjected to chemical analysis to determine organic matter (OM, crude protein (CP in situ and in vitro true digestibility of dry matter. OM and CP intake were estimated by total fecal collection. Effective extent of degradation of the OM and CP was calculated hourly and total 24 hours. From the hourly quantity of OM and CP degraded, a synchrony index of CP to OM was calculated, and from the total 24 hours degradation, degraded organic matter intake and crude protein intake were also estimated. Sampling date was the main effect that determined the variation of diet OM and CP degradation parameters. Degraded crude protein intake as a proportion of degraded OM was affected by sampling date and was correlated to rainfall. During winter of the first year degraded crude protein intake was below the requirements for maintenance or to promote growth for range goats weighing 40 kg. Even though, synchrony index between OM and CP degradation was affected by sampling date goats maintained a high synchrony index throughout the years.

    2013-06-01

    Full Text Available Sixteen goats fitted with a rumen cannula were used in completely randomized block design to test the effects of dietary crude palm oil (PO, palm kernel cake (PKC and decanter cake (DC on rumen total protozoa counts, rumen fermentation, and digestibility. Goats received once daily (1.5% of BW one of four concentrate diets: reference diet (RD, DC diet (DCD, PKC diet (PKCD and RD plus 5% PO diet (CPOD. The RD was based on corn grain and soybean meal and was fed to all goats for 28 days before the start of a 30-day experiment. Organic matter (OM digestibility was reduced (P < 0.05 by feeding DCD, whereas digestibility of acid detergent fiber (ADF was higher (P < 0.0001 in the goats fed PKCD. The digestibility of neutral detergent fiber (NDF was higher (P < 0001 in goats fed PKCD followed by those fed DCD, CPOD and CD. Ammonia–N concentration was lower (P < 0.001 for treatments DCD, PKCD and CPOD than for treatment RD. Volatile fatty acid (VFA concentrations were lower (P < 0.05 for treatments PKCD and CPOD than for treatments RD and DCD. Total protozoa counts were higher (P < 0.001 for treatment CD than for other treatments. It was concluded that the dietary DC, and PKC could be included in the diet of goats up to 80% without any adverse effects on dry matter intake; however, rumen fermentation parameters and total protozoa counts were changed.

    During yogurt manufacture, the lactose fermentation and organic acid production can be used to monitor the fermentation process by starter cultures and probiotic bacteria. In the present work, a simple, sensitive and reproducible high-performance liquid chromatography with dual detectors, diode array detector and refractive index was validated by simultaneous analysis of carbohydrates and organic acids in goat milk yogurts. In addition, pH and bacterial analysis were performed. Separation of all the compounds was performed on an Aminex HPX-87H column (300×7.8 mm, 9 µm) utilizing a 3 mmol L(-1) sulfuric acid aqueous mobile phase under isocratic conditions. Lactose, glucose, galactose, citric, lactic and formic acids were used to evaluate the following performance parameters: selectivity, linearity, precision, limit of detection (LOD), limit of quantification (LOQ), decision limits (CCα), detection capabilities (CCβ), recovery and robustness. For the method application a six goat milk yogurts were elaborated: natural, probiotic, prebiotic, symbiotic, cupuassu fruit pulp, and probiotic with cupuassu fruit pulp. The validated method presented an excellent selectivity with no significant matrix effect, and a broad linear study range with coefficients of determination higher than 0.995. The relative standard deviation was lower than 10% under repeatability and within-laboratory reproducibility conditions for the studied analytes. The LOD of the method was defined from 0.001 to 0.003 µg g(-1), and the LOQ from 0.003 to 0.013 µg g(-1). The CCα was ranged from 0.032 to 0.943 µg g(-1), and the CCβ from 0.053 to 1.604 µg g(-1). The obtained recovery values were from 78% to 119%. In addition, the method exhibited an appropriate robustness for all parameter evaluated. Base in our data, it was concluded that the performance parameters demonstrated total method adequacy for the detection and quantification of carbohydrates and organic acids in goat milk yogurts.

    Full Text Available Our research activities are designed to support increased economic opportunities and improved quality of life for rural American farmers.  The objective of this paper is to examine our research efforts and determine where we can be more productive and sustainable.  Goat research activities using  Tennessee Stiff-legged (TS, Spanish (SP, Nubian (NU and Boer (BR breeds in different production systems at the International Goat Research Center at Prairie View A&M University,  located on the northeastern corridor of the Gulf Coast region of Texas, approximately 45 miles from Houston, have been examined.  From a diallel crossing experiment we recommended the use of terminal sire TS on the cross of NUxSP females. Goats that were fed at intermediate level of a ration (70% of ad libitum were significantly more efficient (P< 0.05 in converting feed to gain. Comparison of intensive and pasture rearing systems indicated that pasture raised SP kids were significantly heavier (P< 0.05 than intensively raised SP kids, while the opposite was true for TS and BR kids. It would appear that on pasture, the SP kids grew faster than the TS kids. Between breeds, growth performance was higher for the BR and TS breeds in the intensive system, while growth performance was higher for the SP in the pasture system.  It would appear that the SP breed is more adapted to production under pasture (or extensive production system. Even though the TS breed is smaller, under intensive system it grows more efficiently (P< 0.05 than the SP, an intermediate size breed. Under conditions existing in the Gulf Coast region of Texas, breeds that are adapted to the environment are recommended for use in initiating goat production programs. Tremendous potential exist to make a living with goats in this region.

    Goat research in the United States has increased but at a rate less than that in production. Research on goat meat includes nutritional quality, packaging, color, sensory characteristics, and preslaughter management. Goat skins have value for leather, but quality of goat leather has not been extensively studied. Research in the production, quality, antibiotic residues, and sensory characteristics of goat milk and its products has aided development of the US dairy goat industry. Limited progress has been made in genetic improvement of milk or meat production. There is need to explore applications of genomics and proteomics and improve consistency in texture and functionality of goat cheeses. New goat meat and milk products are needed to increase demand and meet the diverse tastes of the American public. Despite research progress in control of mohair and cashmere growth, erratic prices and sale of raw materials have contributed to further declines in US production. Innovative and cooperative ventures are needed for profit sharing up to the consumer level. Internal parasites pose the greatest challenge to goat production in humid areas largely because of anthelmintic resistance. Study of alternative controls is required, including immunity enhancement via nutrition, vaccination, pasture management such as co-grazing with cattle, and genetic resistance. Similarly, the importance of health management is increasing related in part to a lack of effective vaccines for many diseases. Nutrition research should address requirements for vitamins and minerals, efficiencies of protein utilization, adjusting energy requirements for nutritional plane, acclimatization, and grazing conditions, feed intake prediction, and management practices for rapid-growth production systems. Moreover, efficient technology transfer methods are needed to disseminate current knowledge and that gained in future research.

Fifteen male Kacang goats weighing 14.28 ± 3.36 kg (CV = 23.55% weredivided into 5 groups based on body weight. The experimental design used in this study wasRandomized Block Design (RBD with 3 treatments of dietary protein and total digestible (TDNcontents (T1= diet with 9.20% protein and 54.67% TDN; T2= diet with 11.6% protein and 58.61%TDN; T3= diet with 18.33% protein and 65.23% TDN. Parameters observed were feed intake, drymatter intake, crude protein intake, TDN intake, live weight gain (LWG and body composition ofKacang goat. The results showed that feed quality did not significantly affect (P>0.05 dry matter intakeand body composition, but significantly affect (P<0.05 protein intake, TDN intake and LWG. It can beconcluded that the higher quality diet resulted in higher productivity, but the higher quality diet was notaffect body composition of Kacang goat, except body fat gain (%.

  12. Influence of farming system and production purpose on the morphostructure of Spanish goat breeds

    Ana Gonzalez-Martinez

    2014-02-01

    Full Text Available The aim of this study was to examine the possible influence of farming systems, based on the morphostructure of 1,571 female goats drawn from 40 flocks containing seven Spanish breeds (Blanca Andaluza, Blanca Celtiberica, Negra Serrana, Pirenaica, Payoya, Murciano-Granadina and Malagueña raised under four different farming systems. Analysis of morphometric variables showed that the morphostructure of native Spanish goat breeds was linked to the farming system used and thus to the production purpose. The morphostructure of grazing breeds may be more influenced by natural selection within the physical environment and less by human selection. That of stall-fed breeds, by contrast, reflects intense artificial selection aimed at achieving a highly-productive dairy type. For this reason, morphological evaluation systems used in breeding programmes for meat or dual-purpose goat breeds farmed extensively or semi-extensively should be specific, and should reflect the influence of the environment in which these goats are farmed.

    Full Text Available The aim of this study was to identify the effect of zinc-enriched diet fed to goats and their kids on the number of Coccidia oocysts shed by kids, on clinical signs of coccidiosis, weight gains, and kids’ blood plasma concentration of zinc. A total of 22 goat kids were divided into 4 groups of 5 or 6 animals. Goats and kids from the control group did not receive any additional zinc, the second group was supplemented with inorganic zinc (zinc oxide, the third group was given zinc lactate, and the fourth group received chelated zinc. Samples of kids’ faeces were taken weekly from 3 to 9 weeks of their age (a total of 7 samples were taken. Samples of faeces were examined by a quantitative method to detect the number of oocysts. Kids were weighed weekly and their blood was taken in order to determine zinc concentrations in blood plasma. Animals from the group supplemented with zinc chelate and zinc lactate shed a significantly (p ≤ 0.05 lower number of oocysts (13.4% and 11.9%, respectively compared to the number of oocyst shed by control and zinc oxide supplemented groups (25% and 49.7%, respectively. Shedding of oocysts was not accompanied by clinical symptoms of coccidiosis in any of the groups. Kids supplemented with zinc chelate showed significantly highest weight gains and blood plasma concentration of zinc (p ≤ 0.05 as compared to control and inorganic zinc supplemented groups. Organic zinc is to be recommended to be used as a prophylaxis against coccidiosis in goat kids.

    Dairy goat farming is practiced worldwide, within a range of different farming systems. Here we investigated the effects of environmental factors and morphology on milk traits of the Sardinian goat population. Sardinian goats are currently reared in Sardinia (Italy) in a low-input context, similar to many goat farming systems, especially in developing countries. Milk and morphological traits from 1,050 Sardinian goats from 42 farms were recorded. We observed a high variability regarding morphological traits, such as coat color, ear length and direction, horn presence, and udder shape. Such variability derived partly from the unplanned repeated crossbreeding of the native Sardinian goats with exotic breeds, especially Maltese goats. The farms located in the mountains were characterized by the traditional farming system and the lowest percentage of crossbred goats. Explanatory factors analysis was used to summarize the interrelated measured milk variables. The explanatory factor related to fat, protein, and energy content of milk (the "Quality" latent variable) explained about 30% of the variance of the whole data set of measured milk traits followed by the "Hygiene" (19%), "Production" (19%), and "Acidity" (11%) factors. The "Quality" and "Hygiene" factors were not affected by any of the farm classification items, whereas "Production" and "Acidity" were affected only by altitude and size of herds, respectively, indicating the adaptation of the local goat population to different environmental conditions. The use of latent explanatory factor analysis allowed us to clearly explain the large variability of milk traits, revealing that the Sardinian goat population cannot be divided into subpopulations based on milk attitude The factors, properly integrated with genetic data, may be useful tools in future selection programs.

    The aim of this experiment was to study the effects of substituting dietary barley grain with orange pulp or soybean hulls on energy, nitrogen and carbon balance, methane emission and milk performance in dairy goats. Twelve Murciano-Granadina dairy goats in midlactation were selected and divided into three groups based on similar body weight (42.1 ± 1.2 kg) and milk yield (2.16 ± 0.060 kg/goat/day). The experiment was conducted in an incomplete crossover design where one group of four goats was fed a mixed ration of barley grain (BRL), another group of four goats replaced barley grain with orange pulp (OP) and the last group of four goats with soybean hulls (SH). After adaptation to diets, the goats were allocated to individual metabolism cages and intake, faeces, urine and milk were recorded and analysed. Then, gas exchange measurements were recorded by a mobile open-circuit indirect calorimetry system using a head box. Dry matter intake was similar for all three groups (2.03 kg/d, on average). No influence of the diet was observed for energy balance and the efficiency of use of metabolizable energy for milk production was 0.61. The OP and SH diets showed greater (P goats than BRL suggest a negative impact of these diets on rumen bacterial metabolism; probably linked to the lower nitrogen supply of diet OP to synthesize microbial protein and greater content of fat in diet SH. Replacement of cereal grain with fibrous by-products did not increased enteric methane emissions (54.7 L/goat per day, on average). Therefore, lactating goats could utilize dry orange pulp and soybean hulls diets with no detrimental effect on milk performance.

    Haemonchosis caused by Haemonchus contortus causes great economic losses in terms of weight loss, poor quality meat and loss of wool in sheep and goats. Therapeutical trials were conducted by using various allopathic, homeopathic, herbal and biological products. For this purpose total of 120 sheep and goats were randomly divided into groups A, B, C, D, E and F and animals in group A, B, C and D were treated with Ivermectin, Azedarachta indica (neem Leaves) Powder, Trematox (a homeopathic drug), EM-Biovet (Effective micro-organisms) respectively. Whereas E and F were kept as infected untreated and control respectively. Efficacy of drugs was measured based on reduction in EPG count, it was found that ivermectin at recommended dose rate is found more effective; Azedarachta Indica (Neem) found second and Trematox third drug of choice in combating the infection against haemonchosis, whereas EM Biovet was inferior to other drugs. In these studies it was found that Azedarachta Indica (Neem) is cheapest and easily available drug than others. Comparison based on reduction in EPG count indicated that Azedarachta indica and Trematox were fairly affective in combating haemonchosis but EM Bio-vet fail to cure all cases of haemonchosis. It was also noted that all drugs were more affective at two-dose level as compared to one dose level. Ivermectin proved to be best drug against haemonchosis. Efficacy of Azedarachta indica (neem) found to be closer to Ivermectin and EM Bio-vet was inferior as compared to Ivermectin. (author)

    Full Text Available The availability of feed and their efficiency of use throughout the year represent the most important constraint affecting the productivity of animals in any agro-ecosystems. Beside being the largest contributor to the total production cost, logistically feeds need to be available on a daily basis across the animal’s life time. In order to be competitive, goat production system must be directed toward the optimum utilization of inconventional feedstuffs such as crop residues and agro-industrial by-products. The horticulture crops provide various crop-residues and by products from the processing of its main products. These biomass are potential feedstuffs that could be used to support the production of goats. The processing of passion fruits (Passiflora edulis yield by products such as fruit shells and seeds. These products are good energy and protein sources for growing goats. Oriental radish (Raphanus sativus by-products composed by damaged root parts and culls have high digestible energy and low ether extract content, but have very high moisture content. The pineapple by-products composed by the peel and bagasse of the fruit could be used as energy source for goats. Other horticulture by-products or residues such as citrus pulp, abandoned citrus fruit, forages from Ipomea batatas are of great potential as feeds for goat production. Preserving technology like ensiling could be implemented in utilising those biomass categorized as wet by-products such as pineapple and oriental radish by-products. The technology of complete feed is an effective means in utilizing some of those products with relatively low palatability or to increase its inclusion level in diets. Introducing shade-tolerant forage species as intercrops such as Stenotaphrum secundatum, Brachiaria humidicola and Arachis pintoi in the citrus plantation should increase feed capacity of the area. The multi-purpose trees such as Indigofera sp. and Calliandra calothyrsus both are

    2016-04-01

    Full Text Available Dates fruit waste (DFW is a by-product of dates juice industry that contains high energy. So, it is suitable for an energy source in dairy goat ration. This study was conducted to observe the effect of DFW utilization in the ration on energy partition and productivity of lactating dairy goats. The experimental design was randomized block design using 9 primiparous lactating dairy goats. There were three types of ration as treatments used in this study, i.e. R0= 35% forage + 65% concentrate, R1= 35% forage + 55% concentrate + 10% DFW, and R2= 35% forage + 45% concentrate + 20% DFW. Data were analyzed using ANOVA and polynomial orthogonal test. The evaluated variables were dry matter intake (DMI, energy partition including energy intake, digestible and metabolizable energy, fecal and urine energy, energy in methane gas, and energy in milk, milk production and quality. The results showed that the linear decreased of DMI, energy intake, digestible energy, metabolizable energy, and urine energy with the increased of DFW level in the rations. The use of 10% DFW (R1 showed the lowest energy loss through feces and methane gas of all treatments about 1089.57 kcal/head/d and 2.36 kcal/head/d, respectively. The use of DFW did not affect energy retention in milk. The utilization of DFW in ration did not significantly prevent the decline of milk production and milk quality. It can be concluded that DFW can be used as an alternative feed for the lactating dairy goat up to 10% in the ration.

    Two trials were performed to assess the meat fatty acid profile of goat kids from different genotypes, production systems and sex. In the first trial, genotype effect was determined in 24 suckling male kids from Turkish Saanen, Maltese and Gokceada breeds. In the second trial, male and female Gokceada Goat kids were used to compare the effect of extensive and semi-intensive production systems on fatty acid composition of meat. Significant genotype effect was observed in the percentages of myristic acid (C14:0), palmitic acid (C16:0), oleic acid (C18:1 n-9), linolenic acid (C18:3 n-3), arachidonic acid (C20:4 n-6) and docosahexaenoic acid (C22:6 n-3), despite no differences on the ratios of polyunsaturated fatty acids to saturated fatty acids (PUFA/SFA) and n-6/n-3 (P > 0.05). The effect of production system had also significant effects on fatty acids, but sex only influenced significantly stearic acid (C18:0), C18:1 n-9 and C18:3 n-3 fatty acids and total PUFA level and PUFA/SFA ratio. This study confirms that dairy breeds are prone to produce higher levels of unsaturated fatty acids in their muscle. Meanwhile, meat from Gokceada goat kids, which is one of the indigenous breeds in Turkey, had similar PUFA/SFA and n-6/n-3 ratios to Turkish Saanen and Maltase. © 2014 Japanese Society of Animal Science.

    Microalgae might be considered as an alternative source of fat and/or protein for ruminant's diets. However, changes in populations of ruminal micro-organisms associated with biohydrogenation process, methane and ammonia production in response to microalgae dietary supplementation have not been well characterized. Thus, 16 cross-bred goats were divided into two groups. Each goat of both groups was fed individually with alfalfa hay and concentrates separately. The concentrates of the control group had no microalgae while those of the treated group were supplemented with 10 g lyophilized Chlorella vulgaris/kg concentrate (chlor). On the 30th experimental day, samples of rumen fluid were collected for microbial DNA extraction, fatty acid profile and enzyme activity analyses. The results showed that the chlor diet compared with the control increased significantly the populations of Methanosphaera stadtmanae, Methanobrevibacter ruminantium and Methanogens bacteria and protozoa in the rumen of goats. A significant reduction in the cellulase activity and in the abundance of Ruminococcus albus, and a significant increase in the protease activity and in the abundance of Clostridium sticklandii in the rumen liquid of goats fed with the chlor diet, compared with the control, were found. Chlorella vulgaris supplementation promoted the formation of trans C 18:1 , trans-11 C 18:1 and monounsaturated fatty acids (MUFA), while the proportions of C 18:0 and long-chain fatty acids (LCFA) reduced significantly in the rumen liquid of goats. This shift in ruminal biohydrogenation pathway was accompanied by a significant increase in Butyrivibrio fibrisolvens trans C 18:1 -producing bacteria. In conclusion, the supplementation of diets with microalgae needs further investigation because it enhances the populations of methane-producing bacteria and protozoa.

    The aim of this study was to examine differences in the microbiological profile and antimicrobial resistance of bacteria isolated from milk from organic and conventional sheep and goat farms. Twenty-five organic and 25 conventional sheep and goat farms in the region of Thessaly, Greece participated in this study. A standardised detailed questionnaire was used to describe farming practices. A total of 50 samples were collected and analysed for total viable count (TVC), total coliform count (TCC) and somatic cell count (SCC), while Staphylococcus aureus and Escherichia coli were isolated using standard methods. Isolates were identified at species level by Api-test and Matrix-Assisted Laser Desorption/Ionisation-Time of Flight Mass Spectrometry (MALDI-TOF MS). Susceptibility to a panel of 20 for E. coli and 16 for S. aureus antimicrobials was determined by the agar dilution method. Pulsed Field Gel Electrophoresis (PFGE) was performed for S. aureus and E. coli isolates to determine predominant clones. Lower counts of TVC, TCC and SCC were identified in milk from the organic farms, possibly due to differences in the hygienic farming practices found on those farms. API-tests and MALDI-TOF MS showed no significant differences in the S. aureus and E. coli isolates. Overall, antimicrobial resistance rates were low, while a statistically higher percentage was estimated among strains originating from conventional farms in comparison with organic farms, possibly due to the restriction of antibiotic use in organic farming. PFGE revealed diversity among S. aureus and E. coli populations in both organic and conventional farms indicating circulation of 2-3 main clones changing slightly during their evolution. Consequently, there is evidence that milk from the organic farms presents a better microbiological profile when compared with milk from conventional farms.

    Progressing economic development in Southeast Asia has increased regional demand for goat meat, leading to expanding production by smallholders and recently, development of commercial farms. In Laos, an emerging export market for goats into Vietnam has led to increased goat numbers, with potential increases in risk of disease, particularly endoparasitism. A cross-sectional survey investigated the prevalence of gastrointestinal parasites in indigenous Kambing-Katjang goats on smallholder farms (n = 389) in 8 villages where no anthelmintic treatments were in use, providing comparisons with a case study of imported Boer crossbred goats (n = 45) on a commercial farm where intensive anthelmintic treatments were required to manage mortalities attributable to Haemonchosis. Clinical examinations, collection of faecal samples, and pathological examination on the commercial farm, accompanied collection of information on animal gender, age and body weight, with data analyses performed in Genstat. Faecal samples contained eggs of multiple endoparasitic species, with Strongyles spp. and coccidian oocysts of Eimeria spp. most prevalent. Significant associations between the presence of endoparasites and the farm type (smallholder versus commercial; p commercial farm having Stronglyes spp. and Eimeria spp. of 1.3 (CI = 0.6-2.9) and 4.8 (CI = 2.5-9.1). Mortalities from endoparasitism were only recorded at the commercial farm, with the loss of 24 goats in the final 3 months of the dry season (Feb-April). This study identified a moderate prevalence of multiple endoparasitic species in smallholder goat farms that appeared well-tolerated, whereas in the developing commercial system, endoparasites posed significant risks to enterprise viability, even with use of anthelmintics. Further studies on endoparasite control are required if commercial tropical goat meat production is to prove sustainable and assist in addressing regional food security, plus provide a pathway to

    The effect of fermentation with Lactobacillus rhamnosus GG on the product quality of goat milk yogurt using traditional yogurt starter was studied through single-factor experiments and orthogonal experiments. The optimum fermentation condition was evaluated by the titratable acidity of goat milk yogurt, water-retaining capability, sensory score, and texture properties; the fatty acids of the fermented goat milk were determined by a gas chromatograph. Results indicate that high product quality of goat milk yogurt can be obtained and the content of short-chain and medium-chain fatty acids can be decreased significantly when amount of sugar added was 7%, inoculation amount was 3%, the ratio of 3 lactic acid bacteria--Lactobacillus delbrueckii ssp. bulgaricus, Streptococcus thermophilus, and L. rhamnosus GG--was 1:1:3, and fermentation temperature was 42°C.

    Full Text Available The relationship between the quality of goat milk and the feeding management in organic farms located in the Veneto Region was evaluated. Five organic dairy goat farms with Alpine and Saanen breeds were considered. Samples of bulk milk and feeds were collected monthly and analysed for chemical composition. Milk fatty acids profile was also determined. All data were submitted by ANCOVA analysis using breed (B, time of sampling (ST and B x ST as fixed effects and dry matter intake (DMI, dietary concentrations of crude protein (CPc, NDF (NDFc, starch (starchc, and use of grazing as linear covariates. Milk urea N was positively affected by DMI (r=3.64; P<0.05 and negatively by starchc (r=-5.91; P<0.05 and total bacterial count increased significantly (P<0.05 with the increase of CPc and starchc. DMI affected positively the milk fatty acid (FA profile by increasing of PUFA (P<0.01, n-3 (P<0.001 and n-6 (P<0.05 acids and decreasing of SFA (P<0.05 levels in milk. Opposite effects on FA profile were observed by CPc, NDFc and starchc. The use of grazing only caused a significant increase (P<0.05 in the content of CLA in milk.

    Mixed grazing systems combining sheep and cattle have shown better growth performance for one or both species. This observation has been attributed to their complementary feeding behaviour and the reduced host infection by gastrointestinal nematodes. Less attention has been paid to mixed grazing systems combining goats and cattle. Here, continuously grazing goats mixed with cattle (M) were compared with control goats reared alone (C) under tropical conditions. The comparison was conducted with gastrointestinal nematode-infected (I) and non-infected (nI) goats. Thus, the four treatments were cattle with gastrointestinal nematode-infected goats (MI), gastrointestinal nematode-infected goats alone (CI), cattle with non-infected goats (MnI) and non-infected goats (CnI). Average daily gain (ADG, g/day) and grass production were measured for the four groups of animals (six goats and two heifers treated with MI or MnI) grazing for 3 months on 4 subplots. Monthly measurements were performed over 5-day periods. This pattern was replicated in space for a second set of four subplots and in time for six successive cohorts of animals (bands 1 to 6). The ADG of goats in mixed grazing conditions was higher than controls irrespective of the infection status (32.6 v. 18.4 g/day for MI v. CI; 44.2 v. 33.5 g/day for MnI v. CnI). Concomitantly, the average biomass was lower for mixed grazing animals compared with controls (174 v. 170 for MI and MnI; 235 v. 208 for CI and CnI, respectively), suggesting better use of the sward. For daily BW gain (g/kg DM), mixed grazing also yielded better results than the control (1.88 v. 0.52 g BW/kg DM per day for MI v. CI; 2.08 v. 1.47 g BW/kg DM per day for MnI and CnI). Mixed grazing of goats and heifers offers a promising alternative for increasing goat and overall animal production as well as improving the management of pastures.

    Full Text Available A total of 1021 randomly selected serum samples of adult male goats that had been screened for trypanosome infection were assayed for sperm antibodies using the immunoperoxidase staining technique. The result of the trypanosome screening revealed that 586(57.39% goats were positive for trypanosome infection, while 435(42.61% were negative. The assay for sperm antibodies showed that 482(47.21% animals were positive, while 539(52.79% were negative. In the group that was positive for trypanosome infection, 364(62.12% animals were positive, whereas 222(37.88% were negative for sperm antibodies (P<0.001. The group that was negative for trypanosome infection, had a significantly lower number and proportion 118(27.13% of positive compared to 317(72.87% negative for sperm antibodies. Out of a total 482 goats that were positive for sperm antibodies, a significantly higher number, 364(75.52%, were positive than 118(24.48% that were negative for trypanosome infection (P<0.001. In the group that was found negative for sperm antibodies, a significantly lower proportion, 222(41.19%, was positive compared to 317(58.81% that were negative for trypanosome infection (P<0.001. Seropositivity to sperm antibodies was positively correlated to trypanosome infection (P<0.001. Further work on the pathogenesis of sperm antibody production in trypanosome infection is advocated.

    Expansion of goat improvement programs requires exploration of the factors that influence the production system and breeding initiatives. Characterization of goat breeds or populations is crucial in providing information on prevalent goat types and their attributes and may suffice as a guideline on conservation, development, and selection for improved productivity. This study investigated the existing village goat production system and phenotypic diversity of the different village populations from four South African provinces. The study further investigated the use of phenotypic attributes to classify goats to breeds or populations. Data was collected from 142 households in 26 villages of the Eastern Cape (n = 2 villages), KwaZulu-Natal (n = 6 villages), Limpopo (n = 13 villages), and North West (n = 5 villages) provinces through a survey. Individual interviews and focus group discussions revealed that the mean goat herd size per household was least in Limpopo at 13.2 ± 12.40 and highest in Eastern Cape (34.18 ± 28.36). Flocks had more (p Goats were kept mainly for meat, for selling, and for ritual ceremonies. The goat production system was mainly scavenging. Goat health was a major challenge across households and villages. Qualitative traits such coat, horn, ears, and wattle characteristics were recorded for populations of village goats (n = 319) and a feral Tankwa breed (n = 50). The dominant coat pattern was plain (74.53%) with black as the most common coat color (31.98%). Across breeds, a majority (88.08%) of the goats had horns, and 7.59% had wattles while 56.64% had beard. Adult goats (goats formed their own cluster separated from commercial meat type breeds and the Venda and Zulu ecotypes. The discriminant function analysis correctly classified 90.41% of the Zulu goats and 82.93% of the Xhosa village populations. None of the Savanna goats were correctly classified. The study demonstrated diversity in village goat

    Digestibility trials were conducted on Murrah buffaloes and Barbari goats with rumen cannulae in the rumen to determine the digestibility of the feed constituents and the production rates of bacteria and total VFA were estimated in the rumen by isotope dilution technique. The bacterial cells growth in the rumen was more in goats than buffaloes when fed ad libitum and calculated on equal feed intake, where as, in buffaloes fed on restricted diet equal to the goats the production of bacteria and VFA were higher. Goats converted 54.04 percent of their dietary nitrogen into microbial nitrogen which was more than twice of buffaloes. (author)

  14. Murciano-Granadina Goat Performance and Methane Emission after Replacing Barley Grain with Fibrous By-Products.

    Carla Ibáñez

    Full Text Available The aim of this experiment was to study the effects of substituting dietary barley grain with orange pulp or soybean hulls on energy, nitrogen and carbon balance, methane emission and milk performance in dairy goats. Twelve Murciano-Granadina dairy goats in midlactation were selected and divided into three groups based on similar body weight (42.1 ± 1.2 kg and milk yield (2.16 ± 0.060 kg/goat/day. The experiment was conducted in an incomplete crossover design where one group of four goats was fed a mixed ration of barley grain (BRL, another group of four goats replaced barley grain with orange pulp (OP and the last group of four goats with soybean hulls (SH. After adaptation to diets, the goats were allocated to individual metabolism cages and intake, faeces, urine and milk were recorded and analysed. Then, gas exchange measurements were recorded by a mobile open-circuit indirect calorimetry system using a head box. Dry matter intake was similar for all three groups (2.03 kg/d, on average. No influence of the diet was observed for energy balance and the efficiency of use of metabolizable energy for milk production was 0.61. The OP and SH diets showed greater (P < 0.05 fat mobilization (-42.8 kJ/kg of BW0.75, on average than BRL (19.2 kJ/kg of BW0.75. Pentadecanoic acid (15:0 and heptadecanoic acid (17:0 were potential biomarkers of rumen function because the higher contents found in the milk of OP and SH goats than BRL suggest a negative impact of these diets on rumen bacterial metabolism; probably linked to the lower nitrogen supply of diet OP to synthesize microbial protein and greater content of fat in diet SH. Replacement of cereal grain with fibrous by-products did not increased enteric methane emissions (54.7 L/goat per day, on average. Therefore, lactating goats could utilize dry orange pulp and soybean hulls diets with no detrimental effect on milk performance.

  15. The Prospect of Using Complete Feed in Goat Production: A Review on its Utility and Physical Form and Animal Responses

    Simon P Ginting

    2009-06-01

    Full Text Available Complete feed is a strategic feeding system that has been widely adopted by the dairy cattle industry, but it has been rarely practised in goat enterprises. The prospect of using complete feed for goat production could be considered from two aspects, namely 1 its relevancy to the goat metabolic requirement, and 2 its potential as an effective means for maximal utilization of crop residues and agro-industrial byproducts as alternative feeds. Metabolically, the higher energy requirement and the lower gut capacity of goats due to its relatively smaller body size make this animal more adapted to feedstuffs with denser nutrient contents as typified by the complete feed. As complete feed is characteristically dry, it has potential to cause hypovolemia and induce later a lower feed consumption when fed to goats. But, this event occurs only during the initial meal and the condition returns to the normal state thereafter. Total saliva secretion tend to decrease by consuming dry feed which can cause parakeratosis, laminitis or acidosis. However, these metabolic disorder could be prevented by formulating complete feed with optimal roughage/concentrate ratio. Review from literatures showed that, when used in complete feed, the inclusion rate of several low palatability crop residues or agro-industrial ranged from 15 to 60%. The roughage/concentrate ratio was in the range of 0.25 to 3.0. Some physical characteristics are important for effective complete feed such as the particle size of roughage, the content of physically effective fibre and the form of the complete feed. Complete feed processed into pellet generally resulted in better performances. The ME and CP content of complete feed used ranged from 1800 to 2800 kcal/kg DM and from 15 to 20%, respectively. The rate of feed intake by goats receiving complete feed ranged from 2.0 to 4.9% BW, the ADG ranged from 40 to 145 g, FCR ranged from 5.2 to 13.0 and DM digestibility ranged from 62 to 81%. These

    Jyoti Lakhanpal

    2017-07-01

    Full Text Available The present study was carried out to characterize and compare the production potential and antibiotic susceptibility of probiotics isolated from goat, cow and buffalo milk. The probiotics isolated from milk fermented curd were compared with regard to their number, morphology, gram staining, motility, bile salt tolerance, pH-resistance, catalase activity, oxidase production and antibiotic resistance. We demonstrated that the probiotics isolated from milk fermented curd of all three species were gram positive, motile, catalase negative, and oxidase negative and were able to produce lactic acid. Further, we observed that buffalo milk is more potent in forming curd with the highest count of probiotics per ml (3.53 × 10!5 as compared to cow (5.8 × 10!6 and goat milk (7×10!7; moreover, goat milk bacterial isolates were more tolerant to acidic pH but were less bile-salt tolerant than cow milk. Also, probiotics isolated from goat milk curd were more resistant to antibiotics (resistant to 12 out of 15 screened antibiotics than those from cow and buffalo milk (resistant to 8-9 antibiotics. This report shows that goat milk fermented products possess the highest antibacterial potential and are highly acid-tolerant.

    Stirred yogurt manufactured using probiotic culture which usually called Rayeb milk in the Middle East region is one of the most important functional fermented milk products. To increase the health and functionality properties to this product, some ingredients like fruits, cereal, and whey protein are used in production. This study was carried out to prepare functional Rayeb milk from goat's milk, barley flour (15%) and honey (4%) mixtures using ABT culture. Also, vanilla and cocoa powder were used as flavorings. Adding barley flour and honey to goat's milk increased curd tension and water-holding capacity and decreased coagulation time and susceptibility to syneresis. The values of carbohydrate, total solids, dietary fiber, ash, total protein, water soluble nitrogen, total volatile fatty acids, unsaturated fatty acids, oleic, linoleic, α-linolenic acids, and antioxidant activity were higher in Rayeb milk supplemented with barley flour and honey than control. The viabilities of Lactobacillus acidophilus and Bifidobacterium lactis Bb12 (Chr. Hansen's Lab A/S) increased in fortified Rayeb milk. The recommended level of 10 7  cfu g -1 of bifidobacteria as a probiotic was exceeded for these samples. Addition of vanilla (0.1%) or cocoa powder (0.5%) improved the sensory properties of fortified Rayeb milk.

    Full Text Available Methanogenesis in the rumen is thought to represent 2-12% loss of energy intake. The energy loss as methane can decrease animal productivity and feed efficiency. In addition, methane is potentially involves in global warming that affects the atmosphere adversely. A research to improve PE dairy goat productivity and reduce enteric methane emission by supplementation of calliandra and complete rumen modifier (CRM was conducted for 6 months. In this experiment 20 PE dairy goats were divided into five blocks according to body weight. The experimental design used was a randomized block design that consisted of four treatments, A. Elephant grass 50% + concentrate 50% (control, B. Elephant grass 40% + concentrate 40% + calliandra 20%, C. Elephant grass 50% + concentrate 48% + CRM 2% and D. Elephant grass 40% + concentrate 38% + calliandra 20% + CRM 2%. Data were analyzed statistically using ANOVA and Duncan test. The result showed that calliandra and CRM did not affect nutrient consumption, except that protein consumption increased (P < 0.05 in calliandra treatments (B and D. Nutrient digestibility increased in CRM (C treatment, while other treatments did not differ from control. CRM also increased total bacteria (36.84%, milk production (67.21%, milk fat (25.0%, and reduced enteric methane production (65.71%. The improvement of milk production in CRM treatment (C was followed by better feed efficiency than other treatments. In conclusion, CRM was more effective than calliandra in improving milk production of PE dairy goats and reduced enteric methane emission, but its effectivity was reduced in combination with calliandra.

    Goat "sarapatel" is a product made from blood and viscera. For the first time, the microbiological and nutritional quality of "sarapatel" samples (n=48) sold under different conditions (in street markets, butcher shops, and supermarkets under refrigeration, frozen or at room temperature) was evaluated. Goat "sarapatel" is a nutritive food, with each 100 g providing, on average, 72 g of moisture, 2 g of ash, 18 g of protein, 9 g of lipids, 2 g of carbohydrates, 282 mg of cholesterol, and high amounts of unsaturated fatty acids and essential amino acids. The analysis of the "sarapatel" samples shows that none of them contain Salmonella spp. or L. monocytogenes. High counts (>104) of total coliforms, thermotolerant coliforms, and sulfite-reducing Clostridium were detected, and coagulase-positive Staphylococcus was found in 31.25% of samples. The storage conditions evaluated (refrigeration, frozen or at room temperature) did not affect the physicochemical quality of the "sarapatel"; however, the unsatisfactory microbiological quality indicates that it is necessary to improve the health-sanitary aspects of the processing and sale of this product.

    2013-03-01

    Eight Merino sheep (49.4 ± 4.23 kg BW) and 8 Alpine goats (53.2 ± 2.51 kg BW) were used to study the effect of ingestion of quebracho tannins on salivation. Four sheep and 4 goats were individually fed a daily allotment of 20 g DM of alfalfa hay/kg BW (Control). Another 4 sheep and 4 goats were also given 20 g DM of alfalfa hay/kg BW supplemented with 50 g of quebracho/kg DM (Tannin) for a period of 64 d. The saliva secretion from the left parotid gland was collected by insertion of a polyvinyl chloride catheter into the parotid duct and the amount of parotid saliva produced recorded over three 48-h periods on d 1 and 2 (P1), d 31 and 32 (P2), and d 61 and 62 (P3) after the tannin feeding was initiated. The total amount of saliva produced was estimated from rumen water kinetics determined on d 4, d 34, and d 64 of the experiment. Experimental design was completely randomized, with repeated measures on each experimental unit, performing separate analysis for sheep and goats. Parotid saliva production was not affected by the sampling period in either animal species receiving the Control diet. Corresponding values for sheep were 2.04, 2.12, and 2.27 L/d (P = 0.89) and for goats 1.65, 1.79, and 1.86 L/d (P = 0.95). Sheep fed the Tannin diet produced 55, 73, and 107% of the amount of saliva recorded in sheep fed the Control diet on P1, P2, or P3, respectively. Corresponding values in goats were 88, 130, and 134% on P1, P2, or P3, respectively. Estimated total saliva production was not affected (P = 0.50 for sheep and P = 0.97 for goats) by the ingestion of quebracho. There was no difference (P > 0.10) in osmotic pressure, P, Mg, Ca, urea, and protein concentrations in parotid saliva. There were, however, differences in Na and K concentrations in response to the ingestion of quebracho tannins, with Na concentrations increasing (P = 0.05) and K concentrations decreasing (P = 0.04) in sheep saliva and pH increasing (P = 0.05) in goat saliva. In conclusion, the inclusion

    In order to determine the nutritional value and hygienic quality of Lebanese traditional dairy products, a survey was conducted amongst 43 goat keepers. Chemical (pH, acidity, DM, protein and fat) and microbiological (pathogenic bacteria) analyses were carried out on samples from goat milk products in different regions of Lebanon (8 different products). The main products were labneh darfieh from the South, ambarise from Bekaa, serdalli from Chouf and darfieh cheese from the North. The fermented products (laban, labneh, ambarise, serdalli, darfieh cheese and labneh darfieh) had an average pH of 4.02±1.4 and an average lactic acidity of 2.01% ±1.5. As for the non-fermented products (milk and baladi cheese), the average pH was 6.86±0.26, and the average lactic acidity 0.11%±0.04. The dry matter (DM) rate varied from 9.55% to 42.53% (milk and darfieh cheese respectively) while the rate of protein, calculated on DM basis, showed values between 17.82% (laban from the South) and 34.76% (milk). As for the fat, also calculated on DM basis, a minimum value of 6.57% (serdalli) and a maximum of 52.35% (milk) were recorded. All samples were tested and found free of Salmonella and Listeria. Only baladi cheese showed S. aureus counts (47x10 3 CFU.mL-1) exceeding the standard values. Twenty five percent of the samples were found to be contaminated by fecal coliforms and E. coli, with counts of the latter ranging from 102CFU.mL-1 to 33.88 x 10 3 CFU.mL-1 thus making these products inappropriate for consumption. Fifty eight percent of the samples were contaminated with fecal streptococcus with values exceeding 50 CFU.mL-1. (author)

    2003-06-01

    Three experiments were conducted at the farm of the Universiti Putra Malaysia, Serdang, Selangor, Malaysia, to establish a model as an index for estimating rumen microbial protein production. In Experiment 1, six Ferral male goats (wt. 40.2±4.6 kg) were used to determine the endogenous purine derivatives (PD) excreted in the urine by fasting. In Experiment 2, four Ferral male goats (wt. 39.6±1.8 kg) were used to measure the proportion of plasma PD excreted in the urine by using [ 14 C]-uric acid as a marker at two levels of feed intake (40% and 80% voluntary intake), using an incomplete 2x4 Latin square experimental design. The feed consisted of 40% oil palm frond and 60% concentrate (OPFC). In Experiment 3, four Ferral male goats fed (OPFC)) were slaughtered and rumen contents were taken for measurements of purine and total nitrogen contents of mixed rumen microbes. The results showed that endogenous PD (allantoin, uric acid, xanthine and hypoxanthine) excreted in the urine obtained by the fasting trial was 202±17 μmol/kg BW 0 . 75 d - 1. The average percentage recovery of plasma PD excretion in the urine by using [ 14 C)-uric acid as a marker was 83±2.0% (cv=6.88, ranged 76.3-91.4%, n=8). Percentage recovery was not affected by levels of feed intake. The ratio of purine N: total N in the mixed rumen liquid associated bacteria (LAB) was 0.085. In this study, a preliminary model for goats was established by using the information from the recovery of labeled PD [ 14 C]-uric acid and the fasting PD excretion. The model obtained was Y 0.83X + 0.202 x BW 0 . 75 , where Y = PD excretion in the urine (mmol/d) X PD absorption at small intestine (mmol/d) BW 0 . 75 = Metabolic body weight (kg) Thus the microbial nitrogen based on total PD (MNpd) can be calculated as follows: MNpd = 70 x X = 0.992 x X (g/d) 0.085 x 0.83 x 1000 where 0.085 is the ratio of purine-N: total N in mixed rumen microbes, 0.83 is the average of digestibility of microbial purine from published

    Full Text Available Goats show marked progressive seasonal reproduction at latitude > 25° and reproductive management should be adapted to market demands. The present review aimed to discuss the synchronization of ovulation for timed artificial insemination concerning new insights regarding a clean, green and ethical meat and milk production. Today, the induction of ovulation during breeding season or transitions periods is mainly based on progestagens/ progesterone (P4 devices intravaginally inserted on females, at least during 11 days, plus equine chorionic gonadotropin (eCG and prostaglandin F2 alfa administration. In last years a reduction to 20 mg of fluorogestone acetate was made and the successful reutilization of devices containing 0.3 g of P4 indicates a possible reduction of their levels. Shortening the period of exogenous progestagens/P4 priming (5 to 7 days is critical for a rational use of hormones. Moreover, the eCG exchange by socio-sexual cues (male effect seems to see a great advance, even if a previous photoperiod treatment, or equivalent method, being necessary in high latitudes. Research trends on these subjects are expected in future using different goats breeds in distinct regions of world.

    This study was designed to assess the effectiveness of dietary cellulase (243 U/g, derived from Neocallimastix patriciarum) and a Saccharomyces cerevisiae fermentation product (yeast product) on ruminal fermentation characteristics, enteric methane (CH4) emissions and methanogenic community in growing goats. The experiment was conducted in a 5 × 5 Latin square design using five Xiangdong black wether goats. The treatments included a Control and two levels of cellulase (0.8 g and 1.6 g/kg dry matter intake (DMI), i.e. 194 U/kg and 389 U/kg DMI, respectively) crossed over with two levels (6 g or 12 g/kg DMI) of the yeast product. There were no significant differences regarding feed intake, apparent digestibility of organic matter, neutral detergent fibre and acid detergent fibre among all the treatments. In comparison with the Control, the ruminal ammonia N concentration was decreased (p = 0.001) by cellulase and yeast product addition. The activities of carboxymethylcellulase and xylanase were decreased after cellulase addition. Moreover, dietary cellulase and yeast product addition led to a significant reduction (p cellulase and yeast fermentation product can reduce the production of CH4 energy and mitigate the enteric CH4 emissions to a certain degree.

    Full Text Available Effects of freezing and packaging methods on organic acid content of goat cheese during 12 weeks of storage were determined. Goat cheese milk curds were divided into two batches; one of the batches was directly processed in to goat cheese while the other was frozen at -18 °C and stored for six months and processed into cheese after being thawed. Cheese samples were packed in three parts and stored at 4 °C refrigerated control sample and at -18 °C for six months frozen experimental samples. Cheese samples were packed in three different packaging methods: aerobic, vacuum or modified atmosphere. Citric, malic, fumaric, acetic, lactic, pyruvic and propionic acids were analyzed using HPLC method after 1st, 3rd, 6th, 9th and 12th week of storage period. Lactic acid was the main organic acids while pyruvic acid had the lowest content in all cheese samples. Citric and fumaric acid levels of frozen samples increased during storage whereas malic, acetic, pyruvic and propionic acid amounts were decreased compared to the beginning of storage. Packaging methods and freezing process also effected lactic acid levels statistically (p<0.05. Fumaric, acetic and lactic acid concentration of refrigerated samples were increased but citric, malic and propionic acids decreased during storage. Pyruvic acid level did not change significantly. It was determined that organic acid concentrations were effected by freezing process, storage time and packaging methods significantly (p<0.05.

    Full Text Available Abstract Background The effect of choline chloride supplementation through forced drinking combined with concentrate diets containing Ca-fish oil on milk production and milk composition of Etawah Grade goats was evaluated. Choline chloride is an essential component in ruminant diets as it is required for fat metabolism. Method The experiment was conducted in a completely randomized block design with three types of treatments and eight replications. The trial had two successive experimental periods; the first, during the eight weeks of late pregnancy, and the second, during the first 12 weeks of lactation. Twenty-four Etawah Grade does in the second gestation period were divided into three treatment groups. Commercial choline chloride 60 % in corncobs-based powder was used as a source of choline chloride. The treatments were no supplementation (control and supplemented with either 4 g or 8 g/2days of choline chloride. Choline chloride was given to the animals through a forced drinking technique, after dissolving it in 60 ml drinking water. The initial body weight of does was 38.81 ± 3.66 kg. The does were penned individually, and were given fresh chopped King Grass ad libitum and 700 g/day of concentrate diets containing Ca-fish oil, starting eight weeks prior to expecting kidding and continuing for 12 weeks of parturition. Results All nutrient intakes were not significantly different (p > 0.05 among the treatments during the late pregnancy and the lactation periods. Supplementation did not affect (p > 0.05 the average daily gains and feed conversion ratio during pregnancy but gave effects (p < 0.05 on the average daily gains, feed conversion ratio and income over feed cost during lactation. The highest average daily milk yields and 4 % fat corrected milk yields were found in goats supplemented with 4 g/2days of choline chloride and increased by 17.00 % and 24.67 %, respectively, compared to the control.

  17. ORGANIC PRODUCTION OF SHEEP MILK

    Juan Carlos Ángeles Hernández

    2014-04-01

    Full Text Available Organic production systems are based on natural processes, leveraging local resources and decreasing in soil degradation. Effectiveness of milk production of organic systems vs. conventional production systems is a subject open to debate. There are various studies in which there is a positive effect of organic systems in relation to the welfare and animal health, product quality and environmental impact. However, some authors report lower milk yields production and increased susceptibility to environmental conditions compared with those obtained in conventional systems. The lower milk yields in organic systems in Dairy sheep's production, are related to the limited nutritional value, low genetic potential, and the changing environmental conditions. These systems are mainly a production method for a specific market with premium quality products and high standards in their production processes. Thus, a company organic Dairy sheep production should be considered viable when present a positive global sustainability level, that is socially beneficial, economically viable and environmentally responsible.

Molding and mycotoxin formation in organic feeds is one of the most important problems since they adversly affect animal health and toxines pass through the products. Since any chemical method cannot be applied to the organic feedstuffs especially in the struggle with mycotoxin in organic animal production, this should be considered in the measures to be taken and in the systems to be applied and the system should be planned to include organic agriculture. Countries that have established HACCP and ISO 22000 food safety management systems are able to avoid the problem of mycotoxin pollution in organic animal foods. The establishment of the feed safety system based on HACCP principles and its application in production have been made compulsory by Feed Hygiene Regulation issued in Turkey since 2011. In this review, the relationship between organic animal production and mycotoxin, and the precautions to be taken are discussed.

    The objective of this study was to evaluate the effects of the inclusion of palm kernel (Elaeis guineensis) cake in diets for goats on feeding behaviors, rectal temperature, and cardiac and respiratory frequencies. Forty crossbred Boer male, non-castrated goats (ten animals per treatment), with an average age of 90 days and an initial body weight of 15.01 ± 1.76 kg, were used. The goats were fed Tifton 85 (Cynodon spp.) hay and palm kernel supplemented at the rates of 0, 7, 14, and 21% of dry matter (DM). The feeding behaviors (rumination, feeding, and idling times) were observed for three 24-h periods. DM and neutral detergent fiber (NDF) intake values were estimated as the difference between the total DM and NDF contents of the feed offered and the total DM and NDF contents of the orts. There was no effect of palm kernel cake inclusion in goat diets on DM intake (P > 0.05). However, palm kernel cake promoted a linear increase (P kernel cakes had no effects (P > 0.05) on the chewing, feeding, and rumination efficiency (DM and NDF) or on physiological variables. The use up to 21% palm kernel cake in the diet of crossbred Boer goats maintained the feeding behaviors and did not change the physiological parameters of goats; therefore, its use is recommended in the diet of these animals.

    2012-10-01

    Full Text Available Goat milk whey is a byproduct of low economic value, and is perceived within Colombia as industrial waste with a negative environmental impact on ecosystems (BOD and COD of 60,000 ppm and 80,000 ppm respectively. Therefore this paper seeks to characterize this whey, and evaluate the effectiveness of the Lactobacillus Helveticus (LH strain from 0 to 0.91 for the production of lactic acid from whey goat milk enriched with three nutrients. The variables studied follow a Greco-Latin model. To this effect, 16 kinetics were conducted in an intermittent bio-fermenter containing 250 milliliters of goat milk whey wherein the highest production of lactic acid, 17.72 grams per liter, is achieved after 50 hours for a medium containing 2.5% yeast, 0.6% riboflavin, 0.45% ammonium sulfate, and the bio-fermenter operating at 42 ° C. The study concludes that apart from producing lactic acid, LH is an alternative towards avoiding contamination of ecosystems in as much as it would generate an added value to the cheese industry

    Full Text Available Abstract. Previous studies reported that the improvement of endogenous estrogen and progesterone secretions during gestation improved fetal prenatal growth, birth weight, mammary gland growth and development, milk production, litter size, pre- and post-weaning growths. An experiment was conducted to apply the improvement of endogenous secretion of pregnant hormones during pregnancy to increase goat productivity. Thirty-six female ettawah-cross does were divided into 2 groups. Group 1 (control: 18 does included does without improvement of endogenous secretion of pregnant hormones and Group 2 (treatment: 18 does included does with improvement of endogenous secretion of pregnant hormones using follicle stimulating hormones to stimulate super ovulation. The application of this technology increased total offspring born (control: 25 offspring; treatment: 42 offspring, average litter size (control: 1.88; treatment: 2.33, offspring birth weight (control: 2.85±0.50 kg; treatment: 3.82±0.40 kg, and does milk production (control: 1.36±0.34 L/does/day; treatment: 2.10±0.21 L/does/day. Offspring born to does with improved endogenous secretion of pregnant hormones had better weaning weight (control: 11.17±1.99 kg/offspring; treatment: 14.5±1.11 kg/offspring. At weaning period, does with improved endogenous secretion of pregnant hormones produced offspring with total weaning weight twice as heavy as control does (control: 189.9 kg; treatment: 403.6 kg. By a simple calculation of economic analysis, this technology application could increase gross revenue per does until weaning by Rp. 432.888,89. It was concluded that this technology is economically feasible to be applied in small-scale farm. Key Words: follicle stimulating hormone, pregnant hormones, endogenous secretion, super ovulation, ettawah-cross does

  2. Productivity of Bedouin goats: Coping with shortages of water and adequate food

    1988-01-01

    The study was carried out under outdoor summer conditions on goats that were watered only once every four days and goats that were watered once daily. Under each of the watering regimes the goats were fed on alfalfa hay (a high quality roughage), and Rhodes grass and wheat straw, medium and low quality feed respectively. In all trials except one, the goats maintained constant body weights. When goats were watered infrequently they gulped down volumes of water that often caused the osmolarity of the rumen fluid to drop from 360 mosm/kg to about 80 mosm/kg. Over this entire range of osmotic concentration the bacterial populations in the goats' rumen maintained their viability. By reducing the fluid flow through the gut, infrequent drinking helped to extend the time the digesta were retained along the digestive tract. As a result, digestibility of the roughage, particularly that of the low quality feed, was improved. Infrequent drinking was found to reduce the animals' demand for metabolizable energy and, as a result, enabled the goat to balance its energy metabolism on a low energy intake. It also improved the balance in the utilization of dietary protein while not interfering with the ability to recycle urea. It is concluded that the effects of the two deficiencies dealt with in this study are by no means additive. Frequent watering of ruminants in the desert is likely to increase their demand for food, lower their gain in digestible energy, increase their demand for metabolizable energy and make it more difficult for them to balance their energy budget. Improving feed quality for animals grazing in the desert, when water availability declines, is also not advantageous. It may only increase the animals' needs for water, render them dependent on frequent drinking and restrict their grazing area to the close vicinity of water sources. 30 refs, 10 figs, 6 tabs

    Full Text Available Background: The vomeronasal organ (Jacobson’s organ is a chemosensory paired tubular organ located on both sides of the nasal septum at its base. It plays an essential role in reproduction process and social behaviors. Objective: The current study investigated both anatomical and histological structure of the vomeronasal organ (VNO in Egyptian native breeds of goats using cross sectional anatomy, histological techniques and computed tomography (CT. Methodology: A total of thirty heads obtained from adult and apparently healthy goats of both sexes were collected from Beni-Suef slaughterhouse in Beni-Suef province, Egypt then subjected to anatomical, histological and computed topographical studies. Results: Grossly, the VNO appeared as two blind ducts on the either sides of the nasal septum at the floor of nasal cavity extending from the nasal opening of incisive papilla rostrally to the upper 2nd premolar teeth caudally. It connected with mouth by two nasopalatine ducts. The histological examinations revealed two types of lining epithelium; non sensory type lining the cranial portion and the lateral wall of the middle portion of the vomeronasal duct (VND, whereas an olfactory type was the lining epithelium of the medial wall of the middle and the whole caudal portions. The lamina propria submucosa exhibited vascular loose connective tissues, serous glands, nerve bundles and encapsulated by hyaline cartilage. Conclusion: The obtaining olfactory epithelium in VNO may indicate an essential role of this organ in sexual relationships and sociosexual behaviors through perception of pheromones.

    This study aimed to determine the effect of dietary cation and anion difference (DCAD) on milk production and body fluid distribution in lactating dairy goats. Ten dairy goats were selected and divided into two groups, five animals each. Animals received either control DCAD (control, 22.81 mEq/100 g dry matter (DM)) or high DCAD (DCAD, 39.08 mEq/100 g DM). The results indicated that rectal temperature (Tr), respiration rate, milk yield and compositions did not differ between groups. But the percentage change of Tr from the DCAD group was lower than the control group between 09.00 and 13.00 hours. DM intake tended to increase in the DCAD group. Dairy goats in the DCAD group drank more water, but urinary excretion and plasma antidiuretic hormone concentration remained unchanged. Apparent water balance was higher from the DCAD group over 24 h. There was no effect of DCAD on plasma and blood volumes, but tended to increase in extracellular fluid and thereby increased total body water. The present results indicate that animals supplemented with high DCAD increase their total body water and apparent water balance. These results have contributed to the process of adaptation for evaporative cooling and would be useful in slowing down the elevation in Tr. © 2017 Japanese Society of Animal Science.

    The aim was to determine the effect of substituting pumpkin seed cake (PSC) or extruded linseed (ELS) for soya bean meal in goats' diets on milk yield, milk composition and fatty acids profile of milk fat. In total, 28 dairy goats were divided into three groups. They were fed with concentrate mixtures containing soya bean meal (Control; n=9), ELS (n=10) or PSC (n=9) as main protein sources in the trial lasting 75 days. Addition of ELS or PSC did not influence milk yield and milk gross composition in contrast to fatty acid profile compared with Control. Supplementation of ELS resulted in greater branched-chain fatty acids (BCFA) and total n-3 fatty acids compared with Control and PSC (PLA, C18:2n-6; 2.10 and 2.28 g/100 g fatty acids, respectively) proportions compared with Control (2.80 g/100 g fatty acids; PLA/ALA ratio (3.81 v. 7.44 or 6.92, respectively; Psoya bean meal with ELS in hay-based diets may increase beneficial n-3 fatty acids and BCFA accompanied by lowering LA/ALA ratio and increased C18:0. Pumpkin seed cake completely substituted soya bean meal in the diet of dairy goats without any decrease in milk production or sharp changes in fatty acid profile that may have a commercial or a human health relevancy.

    This study aimed to investigate the effect of sunflower seeds, either as whole or as oil, on rumen fermentation, milk production, milk composition and fatty acids profile in dairy goats. Fifteen lactating Damascus goats were divided randomly into three groups (n = 5) fed a basal diet of concentrate feed mixture and fresh Trifolium alexandrinum at 50:50 on dry matter basis (Control) in addition to 50 g/head/d sunflower seeds whole (SS) or 20 mL/head/d sunflower seeds oil (SO) in a complete randomized design. Milk was sampled every two weeks during 90 days of experimental period for chemical analysis and rumen was sampled at 30, 60, and 90 days of the experiment for ruminal pH, volatile fatty acids (tVFA), and ammonia-N determination. Addition of SO decreased (p = 0.017) ruminal pH, whereas SO and SS increased tVFA (pcontent (p = 0.002). Moreover, SO increased milk lactose content (p = 0.048) and feed efficiency (p = 0.046) compared to Control. Both of SS and SO increased (pcontent specially conjugated linolenic acid (CLA) vs Control. Addition of SS and SO increased (p = 0. 021) C18:3N3 fatty acid compared to Control diet. Data suggested that addition of either SS or SO to lactating goats ration had beneficial effects on milk yield and milk composition with enhancing milk content of healthy fatty acids (CLA and omega 3), without detrimental effects on animal performance.

    2013-08-01

    Full Text Available A community mapping procedure was developed to identify and characterize communal land area used for a traditional goat production system. Participatory cartography indicated that producers have good knowledge of their territory; more than 80% of the spatial distribution and localization of the elements and shapes present in the community map agreed with the map constructed with GIS. All flocks were mainly grazed on communal rangelands where the most important native forage plants were Opuntia spp. Yucca filifera, Condalia mexicana, Dalea spp. and Euphorbia cinerasiens, and corn stover the main crop by-product supplement used during dry season.

    It is often inappropriately assumed that the contributions of goats to household economies are similar across flock sizes. A monthly questionnaire was administered to 19, 21, and 13 farmers in Matatiele and Qawukeni and Mankone. Entries and exits to and from each flock were assessed. Most (P < 0.05) kids were born in August (4.92 +/- 0.362 and 2.03 +/- 0.329 for large and small flocks, respectively). Total entries were higher (P < 0.05) in August, September, and October than in the other months. Kid mortality peaked in May and September at 21%. Most (P < 0.05) goats were sold in December (1.06 +/- 0.127 for large flocks and 0.23 +/- 0.135 for small flocks). Goat production efficiency (GPE) was affected (P < 0.05) by month and flock size. The GPE was higher (P < 0.05) in small than in large flocks. The low GPE values obtained in this study indicates the need to devise other indices that factor in the neglected functions of goats when measuring goat production efficiency in communities where the main function of goats is not for sale or consumption.

    2015-08-01

    The objective of this study was to investigate the effects of pistachio by-products (PBP) on nutrient digestibility, blood metabolites and milk fatty acid (FA) profile in Saanen dairy goats. Nine multiparous lactating Saanen goats (on day 90 post-partum, 45 ± 2/kg BW) were randomly assigned to a 3 × 3 Latin square design with three treatment diets: 1) control diet (alfalfa hay based), 2) 32% PBP and 3) 32% PBP + polyethylene glycol (PEG-4000; 1 g/kg dry matter). Each period lasted 21 days, including 14 day for treatment adaptation and 7 day for data collection. Pistachio by-products significantly decreased (p < 0.01) crude protein (CP) digestibility compared with the control diet (64.4% vs. 58.7%), but PEG addition did not differ for CP digestibility of goats fed 32% PBP + PEG and those fed the two other diets. The digestibility of NDF tended (p = 0.06) to decrease for goats fed PBP compared with those fed the control diet. Yields of milk and 4% fat-corrected milk were not affected by dietary treatments. Compared with the control diet, PBP supplementation appreciably changed the proportions of almost all the milk FA measured; the main effects were decreases (p < 0.01) in FA from 8:0 to 16:0 and increases (p < 0.01) proportions of cis-9, trans-11 18:2 and trans-11 18:1, monounsaturated FA, polyunsaturated FA and long-chain FA. The saturated FA, short-chain FA and medium-chain FA proportions were lower (p < 0.01) in goats fed the two PBP supplemented diet than in those fed the control diet and PEG addition led to intermediate proportions of saturated FA, unsaturated and monounsaturated FA. Inclusion of PBP in the diet decreased (p < 0.01) plasma concentrations of glucose and urea nitrogen compared with the control diet. It was concluded that PBP can be used as forage in the diet of dairy goats without interfering with milk yield. Inclusion of 32% PBP in the diet of dairy goats had beneficial effects on milk FA profile but PEG addition to PBP

    1988-01-01

    A heat tolerance index previously developed in cattle was verified in two breeds of goats to identify young heat tolerant animals capable of maintaining liveweight and milk yield on exposure to high environmental temperatures. Twelve Baladi and Bedouin goats were divided into two equal groups and offered either river or salt water (1.8% Mediterranean sea salt). The animals were maintained in climatic chambers at 18 deg. C and 70% RH for an initial four day period followed by another four days at 38 deg. C and 50% RH for seven hours per day. On the second day of each period, each animal was injected intravenously with tritiated water and total body water (TBW) determined. The percentage increase in TBW induced by the high temperature treatment was subtracted from 100 and the TBW heat tolerance index (HTI) was calculated. TBW-HTI correlated significantly with the percentage increase in live body weight (LBW) in goats over a three month exposure to heat stress and with the percentage decrease in daily milk yield over a seven day heat exposure period. TBW-HTI averages of Baladi and Bedouin goats drinking river water were 81 and 88 respectively while those drinking salt water were 86 and 92 respectively. The equations for the predicted percentage increase in liveweight (Y) in a hot environment for Baladi and Bedouin goats were Y = -38.56 + 0.728X and Y = -45.27 + 0.622X respectively, where X is the TBW-HTI index; the predicted percentage decrease in milk yield in a hot environment Y for all goats was Y = 142.28-1.339X.

  13. Developing a predictive model for the energy content of goat milk as the basis for a functional unit formulation to be used in the life cycle assessment of dairy goat production systems.

    Danieli, P P; Ronchi, B

    2018-02-01

    Recent reports on livestock environmental impact based on life cycle assessment (LCA) did not fully consider the case of the dairy goat. Assignment of an environmental impact (e.g. global warming potential) to a specific product needs to be related to the appropriate 'unitary amount' or functional unit (FU). For milk, the energy content may provide a common basis for a definition of the FU. To date, no ad hoc formulations for the FU of goat milk have been proposed. For these reasons, this study aimed to develop and test one or more predictive models (DPMs) for the gross energy (GE) content of goat milk, based on published compositional data, such as fat (F), protein, total solids (TS), solid non-fat matter (SNF), lactose (Lac) and ash. The DPMs were developed, selected and tested using a linear regression approach, as a meta-analysis (i.e. meta-regression) was not applicable. However, in the final stage, a control procedure for spurious findings was carried out using a Monte Carlo permutation test. Because several published predictive models (PPMs) for GE in cow milk and goat milk were found in the literature, they were tested on the same data set with which the DPMs were developed. The best-performing DPMs and PPMs were compared directly with a subset of the individual data retrieved from the literature. Overall, the paucity of direct measurements of the GE in goat milk was a limiting factor in collecting data from the literature; thus, only a small data set (n=26) was established, even though it was considered sufficiently representative of milks from different goat breeds. The three best PPMs based on F alone gave more biased estimates of the GE content of the goat milk than the three new DPMs based on F, F and SNF and F and TS, respectively. Accordingly, three different formulations of FU are proposed, depending on the availability of data including both F and TS (or F and SNF) or F alone. Even though several metrics can be used in defining the FU for milk to

  14. THE FAMILY AGRICULTURE IN THE PRODUCTIVE CHAIN OF SHEEP AND GOAT MEAT IN THE SEMI-ARID OF BRAZIL

    João Virgínio Emerenciano Neto

    2011-12-01

    Full Text Available Given the importance of family farming in food production in Brazil, this review aims to highlight the peculiarities of this productive sector. The labor used in family farming is still not qualified, preventing the application of new technologies in rural activities. This factor is still impressive with regard to management of farms, which is empirically, without sufficient knowledge for entering the market. The meat from sheep sold in Brazil has a large share of the foreign market. The production chain of meat from goat and sheep is dismantled and disorganized, where there is no integration between the chain links. The lack of standard, seasonality of production and low quality products are the limiting factors to the development of this activity in Rio Grande do Norte and the Northeast. Family farming is a palpable alternative to increase the rates of agricultural productivity, take upon them the responsibility to increase food production.

  15. Biogas Production by Co-Digestion of Goat Manure with Three Crop Residues

    Zhang, Tong; Liu, Linlin; Song, Zilin; Ren, Guangxin; Feng, Yongzhong; Han, Xinhui; Yang, Gaihe

    2013-01-01

    Goat manure (GM) is an excellent raw material for anaerobic digestion because of its high total nitrogen content and fermentation stability. Several comparative assays were conducted on the anaerobic co-digestion of GM with three crop residues (CRs), namely, wheat straw (WS), corn stalks (CS) and rice straw (RS), under different mixing ratios. All digesters were implemented simultaneously under mesophilic temperature at 35±1 °C with a total solid concentration of 8%. Result showed that the combination of GM with CS or RS significantly improved biogas production at all carbon-to-nitrogen (C/N) ratios. GM/CS (30:70), GM/CS (70:30), GM/RS (30:70) and GM/RS (50:50) produced the highest biogas yields from different co-substrates (14840, 16023, 15608 and 15698 mL, respectively) after 55 d of fermentation. Biogas yields of GM/WS 30:70 (C/N 35.61), GM/CS 70:30 (C/N 21.19) and GM/RS 50:50 (C/N 26.23) were 1.62, 2.11 and 1.83 times higher than that of CRs, respectively. These values were determined to be the optimal C/N ratios for co-digestion. However, compared with treatments of GM/CS and GM/RS treatments, biogas generated from GM/WS was only slightly higher than the single digestion of GM or WS. This result was caused by the high total carbon content (35.83%) and lignin content (24.34%) in WS, which inhibited biodegradation. PMID:23825574

    The effects of air temperature and relative humidity on thermal equilibrium of goats in a tropical region was evaluated. Nine non-pregnant Anglo Nubian nanny goats were used in the study. An indirect calorimeter was designed and developed to measure oxygen consumption, carbon dioxide production, methane production and water vapour pressure of the air exhaled from goats. Physiological parameters: rectal temperature, skin temperature, hair-coat temperature, expired air temperature and respiratory rate and volume as well as environmental parameters: air temperature, relative humidity and mean radiant temperature were measured. The results show that respiratory and volume rates and latent heat loss did not change significantly for air temperature between 22 and 26°C. In this temperature range, metabolic heat was lost mainly by convection and long-wave radiation. For temperature greater than 30°C, the goats maintained thermal equilibrium mainly by evaporative heat loss. At the higher air temperature, the respiratory and ventilation rates as well as body temperatures were significantly elevated. It can be concluded that for Anglo Nubian goats, the upper limit of air temperature for comfort is around 26°C when the goats are protected from direct solar radiation. Copyright © 2016 Elsevier Ltd.

    Organic producers, traders, and consumers must address 2 issues related to milk: authentication of the production system and nutritional differentiation. The presence of hippuric acid (HA) in goat milk samples has been proposed as a possible marker to differentiate the feeding regimen of goats. The objective of this work is to check the hypothesis that HA could be a marker for the type of feeding regimen of goats by studying the influence of production system (conventional or organic) and feeding regimen (with or without grazing fodder). With this purpose, commercial cow and goat milk samples (n=27) and raw goat milk samples (n=185; collected from different breeds, localizations, and dates) were analyzed. Samples were grouped according to breed, feeding regimen, production system, and origin to compare HA content by ANOVA and honestly significant difference Tukey test at a confidence level of ≥95%. Hippuric acid content was obtained by analyzing milk samples with capillary electrophoresis. This method was validated by analyzing part of the samples with HPLC as a reference technique. Sixty-nine raw goat milk samples (of the total 158 samples analyzed in this work) were quantified by capillary electrophoresis. In these samples, the lowest average content for HA was 7±3 mg/L. This value corresponds to a group of conventional raw milk samples from goats fed with compound feed. The highest value of this group was 28±10 mg/L, corresponding to goats fed compound feed plus grass. Conversely, for organic raw goat milk samples, the highest concentration was 67±14 mg/L, which corresponds to goats fed grass. By contrast, the lowest value of this organic group was 26±10 mg/L, which belongs to goats fed organic compounds. Notice that the highest HA average content was found in samples from grazing animals corresponding to the organic group. This result suggests that HA is a good marker to determine the type of goats feeding regimen; a high content of HA represents a diet

    Here the authors report the objective veterinary clinical measurement of productivity in a representative south Indian Malabari goat herd. The authors show failure to meet pragmatic production targets that are commensurate with the animals' genetic potential or adequate to meet the demands of global food security. The authors suggest that this situation may have arisen as a consequence of animal husbandry constraints and protein undernutrition and imply the involvement of nematode parasitism. Benzimidazole resistance was detected in Haemonchus species, showing the need for better understanding of the principles of sustainable helminth parasite control within the southern Indian context. This study highlights the need to understand the true costs of goat production in seasonally resource-poor environments, while also considering its impact on the overall ecosystem in which the animals are placed. They conclude that pragmatic opportunities for improvements in goat production efficiency lie in the development of problem-focused planned animal health and nutrition management.

    2007-03-01

    The structure and chemical composition of the accessory olfactory bulb (AOB) were examined in male and female goats. Sections were subjected to either Nissl staining, Klüver-Barrera staining, lectin histochemistry, or immunohistochemistry for nitric oxide synthase (NOS), neuropeptide Y (NPY), tyrosine hydroxylase (TH), dopamine beta-hydroxylase (DBH), and glutamic acid decarboxylase (GAD). The goat AOB was divided into four layers: the vomeronasal nerve layer (VNL), glomerular layer (GL), mitral/tufted (M/T) cell layer (MTL), and granule cell layer (GRL). Quantitative and morphometric analyses indicated that a single AOB contained 5,000-8,000 putative M/T cells with no sex differences, whereas the AOB was slightly larger in males. Of the 21 lectins examined, 7 specifically bound to the VNL and GL, and 1 bound not only to the VNL, but also to the MTL and GRL. In either of these cases, no heterogeneity of lectin staining was observed in the rostrocaudal direction. NOS-, TH-, DBH-, and GAD-immunoreactivity (ir) were observed in the MTL and GRL, whereas NPY-ir was present only in the GRL. In the GL, periglomerular cells with GAD-ir were found in abundance, and a subset of periglomerular cells containing TH-ir was also found. Double-labeling immunohistochemistry revealed that virtually all periglomerular cells containing TH-ir were colocalized with GAD-ir.

    Full Text Available A sample of dried fermented goat milk product (Oggtt obtained from the local market of Riyadh city in The Kingdom of Saudi Arabia, was stored for 6 months at 4 °C and subjected to chemical composition analysis before and after storage. The result showed that the sample moisture increased significantly (P ⩽ 0.05 after storage from 7% to 10%, total ash decreased non-significantly (P ⩽ 0.05 from 8% to 7.6%, total carbohydrates decreased non-significantly (P ⩽ 0.05 from 35.5% to 33.8%, protein increased non-significantly (P ⩽ 0.05 from 16 to 16.1 g/l, fat content was found to have the same values in all samples before and after storage at 5%, lactose increased (P ⩽ 0.05 non-significantly from 28.4% to 29%, acidity decreased (P ⩽ 0.05 significantly from 0.45% to 0.39%, and pH decreased (P ⩽ 0.05 non-significantly from 4.3% to 4%. On the other hand, mineral composition showed (P ⩽ 0.05 non-significant results before and after storage. Ca concentration decreased from 118 to 1149 mg/kg and K concentration increased from 185.8 to 1888 mg/kg. While Mg increased from 105 to 123 mg/kg, Zn increased from 8.3 to 8.6 mg/kg, Mn and Fe were found to have the same values of concentrations before and after storage which were 0.2 and 0.1 mg/kg, respectively. Accordingly, we can conclude that Oggtt is a stable product and have a good nutritional value in comparison to daily required amounts for healthy human life.

  9. Spatialization of climate, physical and socioeconomic factors that affect the dairy goat production in Brazil and their impact on animal breeding decisions

    Fernando B. Lopes

    2012-11-01

    Full Text Available Brazil has high climate, soil and environmental diversity, as well as distinct socioeconomic and political realities, what results in differences among the political administrative regions of the country. The objective of this study was to determine spatial distribution of the physical, climatic and socioeconomic aspects that best characterize the production of dairy goats in Brazil. Production indices of milk per goat, goat production, milk production, as well as temperature range, mean temperature, precipitation, normalized difference vegetation index, relative humidity, altitude, agricultural farms; farms with native pasture, farms with good quality pasture, farms with water resources, farms that receive technical guidance, family farming properties, non-familiar farms and the human development index were evaluated. The multivariate analyses were carried out to spatialize climatic, physical and socioeconomic variables and so differenciate the Brazilian States and Regions. The highest yields of milk and goat production were observed in the Northeast. The Southeast Region had the second highest production of milk, followed by the South, Midwest and North. Multivariate analysis revealed distinctions between clusters of political-administrative regions of Brazil. The climatic variables were most important to discriminate between regions of Brazil. Therefore, it is necessary to implement animal breeding programs to meet the needs of each region.

    2009-08-01

    The aim of study was to investigate the effect of genotype on carcass measurements and meat quality characteristics of purebred Hair Goat, Saanen x Hair Goat (F(1) and B(1)) kids under an intensive production system. In total, 24 kids were slaughtered at the age of approximately 133 days. Kids were fattened for 56 days immediately after weaning. Hot carcass weights were 6.78, 7.61 and 7.02 kg and dressing percentages were 49.71, 49.27 and 48.78%, respectively (P > 0.05). Differences between genotypes for carcass measurements and indexes were not significant. Effect of genotype on pH measurements, drip loss, water holding capacity, cooking loss and Warner Bratzler shear force values were not significant. Meat lightness values at 0 h, 1 h and 1 day after cutting were higher in crossbred kids than Hair Goat kids (P meat samples of Hair goat kids at 0 h, 1 h and 1 day measurements (P meat sensory characteristics, except tenderness. Panelists gave lower scores for meat tenderness to F(1) and B(1) crosses compared to purebred Hair Goat kids. In conclusion, higher meat lightness values of crossbred kids, at particularly B(1) level, might have a positive effect on the consumer choices.

    Ahmed, S T; Lee, J-W; Mun, H-S; Yang, C-J

    2015-12-01

    Forty-eight castrated male goats were used to determine the effects of feeding green tea by-products (GTB) on growth performance, meat quality, blood metabolites and immune cell proliferation. Experimental treatments consisted of basal diets supplemented with four levels of GTB (0%, 0.5%, 1.0% or 2.0%). Four replicate pens were assigned to each treatment with three goats per replicate. Increasing dietary GTB tended to linearly increase the overall average weight gain and feed intake (p = 0.09). Water holding capacity, pH and sensory attributes of meat were not affected by GTB supplementation, while cooking loss was reduced both linearly and quadratically (p goat meat were improved by GTB supplementation. Increasing dietary GTB quadratically increased protein and decreased crude fat (p goat meat. The proportions of monounsaturated fatty acid, polyunsaturated fatty acid (PUFA) and n-6 PUFA increased linearly (p meat were lower in the 2.0% GTB-supplemented group in all storage periods (p meat quality, blood metabolites and immune cell proliferation when supplemented as a feed additive in goat diet.

    Full Text Available The objectives of this research are to study the effects of different types of milk and enzymes toward the yield and quality (moisture, ash, protein, fat content, and texture of cheddar cheese and the interaction between those two variables during the process. The types of milk are cow, goat, and soya milk, while the types of enzymes are rennet, papain, and bromelain enzymes. Regarding the procedure, the milk is first pasteurized before CaCl2 and Lactobacillus lactis that acts as the acidifier starter as much as 0.2% (w/v and 0.5% of the milk volume are added respectively. The amount of enzyme added is appropriate for the determination of enzyme dose. The curd is separated from the whey and then 2.5 grams of salt is added to 100 grams of curd. Afterwards, the curd is pressed until the water content decreases (cheese, then ripened for 1 month. The analyses conducted are moisture, ash, protein, fat content, and texture (hardness. The conclusion is the goat milk and the rennet enzyme are the suitable raw material for cheddar cheese production. Furthermore, different types of milk and enzymes affect the yield. However, there is no interaction between the types of milk and enzymes to the yield.

    2014-01-01

    The aim was to compare the carcass and meat quality characteristics of male and female Gokceada Goat kids produced in extensive (n=20) and semi-intensive (n=20) systems. In extensive and semi-intensive produced kids pre-slaughter weights were 17.44 and 12.51 kg; cold carcass weights were 8.66 and 5.35 kg and cold dressing percentages were 54.9 and 49.28%, respectively. The effect of kid sex was not significant on hot and cold dressing percentages, back fat thickness, M. longissimus dorsi section area, carcass fatness and conformation scores, and carcass measurements, while female kids had higher omental and mesenteric fat and kidney knob and channel fat percentages than male kids. Extensive produced kids had lower meat lightness. Panellists evaluated extensive system kids with higher scores of kid odour intensity, flavour intensity and overall acceptability. It was concluded that it would be more appropriate to use an extensive system in Gokceada Goat breeding for kid meat production. © 2013.

    2017-07-01

    Full Text Available Objective Two experiments were conducted to determine the effects of forage-to-concentrate (F:C ratio on the nutrient digestibility and enteric methane (CH4 emission in growing goats and Sika deer. Methods Three male growing goats (body weight [BW] = 19.0±0.7 kg and three male growing deer (BW = 19.3±1.2 kg were respectively allotted to a 3×3 Latin square design with an adaptation period of 7 d and a data collection period of 3 d. Respiration-metabolism chambers were used for measuring the enteric CH4 emission. Treatments of low (25:75, moderate (50:50, and high (73:27 F:C ratios were given to both goats and Sika deer. Results Dry matter (DM and organic matter (OM digestibility decreased linearly with increasing F:C ratio in both goats and Sika deer. In both goats and Sika deer, the CH4 emissions expressed as g/d, g/kg BW0.75, % of gross energy intake, g/kg DM intake (DMI, and g/kg OM intake (OMI decreased linearly as the F:C ratio increased, however, the CH4 emissions expressed as g/kg digested DMI and OMI were not affected by the F:C ratio. Eight equations were derived for predicting the enteric CH4 emission from goats and Sika deer. For goat, equation 1 was found to be of the highest accuracy: CH4 (g/d = 3.36+4.71×DMI (kg/d−0.0036×neutral detergent fiber concentrate (NDFC, g/kg+0.01563×dry matter digestibility (DMD, g/kg−0.0108×neutral detergent fiber digestibility (NDFD, g/kg. For Sika deer, equation 5 was found to be of the highest accuracy: CH4 (g/d = 66.3+27.7×DMI (kg/d−5.91×NDFC (g/kg−7.11× DMD (g/kg+0.0809×NDFD (g/kg. Conclusion Digested nutrient intake could be considered when determining the CH4 generation factor in goats and Sika deer. Finally, the enteric CH4 prediction model for goats and Sika deer were estimated.

  16. Effects of cholesterol on progesterone production by goat luteal cell subpopulations at two different stages of the luteal phase.

    Arikan, Ş; Kalender, H; Simsek, O

    2010-12-01

    The aim of the present study was to evaluate the effects of cholesterol on progesterone production during long-term culturing of luteal cell subpopulations at early and late luteal stages of the goat corpora lutea. Corpora lutea were collected from Angora goats on days 5 and 15 of the oestrous cycle. Luteal cells were isolated by collagenase digestion. The cells were separated into two distinct subpopulations by Percoll density-gradient centrifugation. Both subpopulations of luteal cells staining positively for 3β-HSD activities (5 × 10(4)  cell/well) were cultured with or without 22(R)-hydroxycholesterol (22R-HC) in serum-free culture medium for periods of up to 7 days. Cells were incubated with serum (10%) for the first 18 h of incubation followed by serum-free medium. Cell treatment (10 and 20 μg/ml) was performed on days 1, 3 and 5. Treatment of cells with both concentrations of 22R-HC resulted in significant (p  0.05) on progesterone production in both fractions of cells throughout 7 days of incubation. Treatment of the cells with cholesterol resulted in 2.5- and 9.0-fold increases in progesterone accumulation on day 3 of incubation. Steroid production was maintained throughout the incubations when cells are incubated in serum-free media treated with cholesterol and ITS premix. Cells collected from higher density of percoll layers produced 2.82 and 2.32 times more progesterone, in comparison to the lover density percoll layer, on days 5 and 15 of the oestrous cycle in untreated cell groups, respectively. Progesterone accumulation was decreased as incubation time advanced in all groups of untreated cells. These results demonstrated that goat luteal cell subpopulations secrete substantial amounts of progesterone in response to cholesterol treatment at least for 7 days, and cholesterol is required as progesterone precursor for maintaining a high-level steroidogenesis during long-life culturing of both cell subpopulations. © 2010 Blackwell

  17. Direct duplex real-time loop mediated isothermal amplification assay for the simultaneous detection of cow and goat species origin of milk and yogurt products for field use.

    Kim, Mi-Ju; Kim, Hae-Yeong

    2018-04-25

    A multiple loop-mediated isothermal amplification (LAMP) method was developed to detect cow and goat milk in the field using a portable fluorescence device. For rapid on-site detection, this duplex LAMP assay was used in combination with direct amplification, without DNA extraction. The cow- and goat-specific LAMP primer sets were designed based on the mitochondrial cytochrome b gene, and showed specificity against 13 other animal species in the reactions. The sensitivity of the duplex LAMP assay for cow and goat was 0.1 and 1 pg, respectively. The detection limit for both target species in milk mixtures was 2%. This assay successfully amplified and identified the two target species in 24 samples of commercial milk and yogurt products, with 30 min sampling-to-result analysis time. Therefore, this direct duplex real-time LAMP assay is useful for on-site simultaneous detection of cow and goat milk in commercial products, a capability needed to confirm accurate labeling.

    2012-12-01

    Full Text Available The objective of this study was to produce milk powder from Ettawa-crossbred goat milk and subsequently evaluate the quality of the products. The raw material used was Ettawa-crossbred goat fresh milk with total solid, lactose, fat, and protein content of 15.93%, 4.2%, 4.8% and 4.7%, respectively. Milk with final total solid of 17.5% and 20% were prepared for spray drying by adding skim milk powder. Drying was carried out using a spray dryer type Lamp having nozzle size of 0.05 mm with an inlet temperature of 90°C and an outlet temperature of 45°C. Parameters observed were chemical, physical and microbiological qualities. The data showed that milk powder produced from Ettawa-crossbred goat milk had water content of 1.5-1.7%. Further analysis showed that the acidity, proteins, lactose, and fat content were 0.90%, 28.4%, 21.7%, and 22.5%, respectively. The physical analysis showed that milk powder produced from Ettawa-crossbred goat milk had a higher wettability score (143 seconds as compared to that of commercial products (29 seconds, a higher sieve test score (0.6 g vs 0.004 g, but similar index of insolubility (1.4 ml vs.1.6 ml. The microbiological analysis showed that the Total Plate Count (TPC, Enterobacteriaceae (EB and presumptive coliforms increased during storage either in refrigerator or room temperature. The increase in TPC, EB and coliforms was substantially higher when products were kept at room temperature than in refrigerator. In conclusion, Ettawa-crossbred goat milk powder had a good nutrition quality, but still need improvement for the physicochemical characteristic including wettability and nutritional enrichment for vitamins and minerals by means of fortification.

    Monica Battini

    2015-09-01

    Full Text Available Within the European AWIN project, a protocol for assessing dairy goats’ welfareon the farm was developed. Starting from a literature review, a prototype includinganimal-based indicators covering four welfare principles and 12 welfare criteria was set up.The prototype was tested in 60 farms for validity, reliability, and feasibility. After testing theprototype, a two-level assessment protocol was proposed in order to increase acceptabilityamong stakeholders. The first level offers a more general overview of the welfare status,based on group assessment of a few indicators (e.g., hair coat condition, latency to thefirst contact test, severe lameness, Qualitative Behavior Assessment, with no or minimalhandling of goats and short assessment time required. The second level starts if welfareAnimals 2015, 5 935problems are encountered in the first level and adds a comprehensive and detailed individualevaluation (e.g., Body Condition Score, udder asymmetry, overgrown claws, supported byan effective sampling strategy. The assessment can be carried out using the AWIN Goatapp. The app results in a clear visual output, which provides positive feedback on welfareconditions in comparison with a benchmark of a reference population. The protocol maybe a valuable tool for both veterinarians and technicians and a self-assessment instrumentfor farmers.

    The distribution and quantification of tetracycline, sulfonamide and beta-lactam resistance genes were assessed in slaughterhouse zones throughout meat chain production and the meat products; this study represents the first to report quantitatively monitor antibiotic resistance genes (ARG) in goat and lamb slaughterhouse using a culture independent approach, since most studies focused on individual bacterial species and their specific resistance types. Quantitative PCR (qPCR) revealed a high prevalence of tetracycline resistance genes tetA and tetB in almost all slaughterhouse zones. Sulfonamide resistance genes were largely distributed, while beta-lactam resistance genes were less predominant. Statistical analysis revealed that resistant bacteria, in most cases, were spread by the same route in almost all slaughterhouse zones, except for tetB, blaCTX and blaTEM genes, which occurred in few zones as isolated 'hot spots.'

    Mokhtarpour, A; Naserian, A A; Pourmollae, F; Ghaffari, M H

    2016-08-01

    A lactation experiment was conducted to determine the influence of addition of pistachio by-products extract (PBE) to alfalfa silage (AS) on performance, rumen fermentation, milk yield and composition, and microbial nitrogen synthesis. Eight multiparous dairy goats (1.8 ± 0.25 kg of milk yield) were used in a replicated 4 × 4 Latin square design with a 2 × 2 factorial arrangement of treatments to compare two types of AS (supplemented with or without PBE) with two levels of dietary crude protein (14% vs. 16% CP). Dietary treatments were (i) AS with 14% CP of DM diet without PBE (14%CP-PBE), (ii) AS with 14% CP of DM diet with PBE (14%CP + PBE), (iii) AS with 16% CP of DM diet without PBE (16%CP-PBE) and (iv) AS with 16% CP of DM diet with PBE (16%CP + PBE). PBE was sprayed on fresh alfalfa at a ratio of 500 ml/kg alfalfa DM to get the final concentration of 1% tannin as tannic acid equivalent on DM basis. Intake of CP was greater (p pistachio by-products tannins. Journal of Animal Physiology and Animal Nutrition © 2015 Blackwell Verlag GmbH.

  11. Measurement of the 234U/238U activity ratios in the organs and internal tissues of a domestic goat kid (Capra aegagrus hircus)

    Francesco De Santis; Massimo Esposito

    2015-01-01

    In this paper, we compare the 234 U/ 238 U activity ratios (ARs) in various internal tissues and organs of a goat kid with the ingested 234 U/ 238 U AR to assess isotopic fractionation. The results obtained from soft tissues (i.e., the kidneys, liver, lung, and bladder) that undergo indirect assimilation of uranium from the feed through the bloodstream suggest an increase in the 234 U/ 238 U AR. In contrast, the intestine, bones and feces had the same AR values as the feed. Finally, we broadly assess uranium transfer from the feed to the animal based on the concentration ratio and the feed transfer coefficient. (author)

  14. Virtual Nitrogen Losses from Organic Food Production

    Cattell Noll, L.; Galloway, J. N.; Leach, A. M.; Seufert, V.; Atwell, B.; Shade, J.

    2015-12-01

    Reactive nitrogen (Nr) is necessary for crop and animal production, but when it is lost to the environment, it creates a cascade of detrimental environmental impacts. The nitrogen challenge is to maximize the food production benefits of Nr, while minimizing losses to the environment. The first nitrogen footprint tool was created in 2012 to help consumers learn about the Nr losses to the environment that result from an individual's lifestyle choices. The nitrogen lost during food production was estimated with virtual nitrogen factors (VNFs) that quantify the amount of nitrogen lost to the environment per unit nitrogen consumed. Alternative agricultural systems, such as USDA certified organic farms, utilize practices that diverge from conventional production. In order to evaluate the potential sustainability of these alternative agricultural systems, our team calculated VNFs that reflect organic production. Initial data indicate that VNFs for organic grains and organic starchy roots are comparable to, but slightly higher than conventional (+10% and +20% respectively). In contrast, the VNF for organic vegetables is significantly higher (+90%) and the VNF for organic legumes is significantly lower (-90%). Initial data on organic meat production shows that organic poultry and organic pigmeat are comparable to conventional production (both <5% difference), but that the organic beef VNF is significantly higher (+30%). These data show that in some cases organic and conventional production are comparable in terms of nitrogen efficiency. However, since conventional production relies heavily on the creation of new reactive nitrogen (Haber-Bosch, biological nitrogen fixation) and organic production primarily utilizes already existing reactive nitrogen (manure, crop residue, compost), the data also show that organic production contributes less new reactive nitrogen to the environment than conventional production (approximately 70% less). Therefore, we conclude that on a local

  15. Effect of salt, kinnow and pomegranate fruit by-product powders on color and oxidative stability of raw ground goat meat during refrigerated storage.

    Devatkal, Suresh K; Naveena, B M

    2010-06-01

    Effects of salt, kinnow and pomegranate fruit by-product powders on color and oxidative stability of raw ground goat meat stored at 4+/-1 degrees C was evaluated. Five treatments evaluated include: control (only meat), MS (meat+2% salt), KRP (meat+2% salt+2% kinnow rind powder), PRP (meat+2% salt+2% pomegranate rind powder) and PSP (meat+2% salt+2% pomegranate seed powder). Addition of salt resulted in reduction of redness scores. Lightness increased in control and unchanged in others during storage. Redness scores declined and yellowness showed inconsistent changes during storage. Thiobarbituric acid reactive substances (TBARS) values were higher (PPRP>KRP>control>MS. Therefore, these powders have potential to be used as natural antioxidants to minimize the auto-oxidation and salt induced lipid oxidation in raw ground goat meat. Crown Copyright 2010.

  16. Use of spineless cactus (Opuntia ficus indica f. inermis) for dairy goats and growing kids: impacts on milk production, kid's growth, and meat quality.

    Mahouachi, M; Atti, N; Hajji, H

    2012-01-01

    The objective of this study was to determine the effect of spineless cactus incorporation in food of dairy goats and growing kids on milk production and composition and on kid's growth and meat characteristics. Two experiments were conducted on Tunisian local goats. In the first, 30 females were divided into two groups; goats of Control group were reared on grazing pasture receiving indoor 0.5 kg of hay and 0.4 kg of concentrate. Goats for the second group (Cac-FL) were kept in feedlot and fed cactus ad libitum more 0.5 kg of hay and 0.4 kg of concentrate. In the second experiment, 14 kids were divided into 2 groups receiving 600 g of hay. The Control group received ad libitum a concentrate containing 130 g crude protein (CP) per kg of dry matter. The second group received cactus ad-libitum plus the half concentrate quantity of control one with 260 g CP/kg DM (Cactus). The daily milk production averaged 485 ml for Control group and 407 ml for Cac-FL one. The milk fat content was significantly higher for Control than Cac-FL group. In the second experiment, animals in Control and Cactus groups had similar growth rate. Carcass fat was significantly lower in Cactus than in the Control group. Cactus in the diet was associated with more C18:2 and conjugated linoleic acid as well as a higher proportion of PUFA than Control ones.

    2018-01-01

    In rumen fermentation, fumaric acid (FA) could competitively utilize hydrogen with methanogenesis to enhance propionate production and suppress methane emission, but both effects were diet-dependent. This study aimed to explore the effects of FA supplementation on methanogenesis and rumen fermentation in goats fed diets varying in forage and concentrate particle size. Four rumen-cannulated goats were used in a 4 × 4 Latin square design with a 2 × 2 factorial arrangement of treatments: low or high ratio of forage particle size: concentrate particle size (Fps:Cps), without or with FA supplementation (24 g/d). Fps:Cps was higher in the diet with chopped alfalfa hay plus ground corn than in that with ground alfalfa hay plus crushed corn. Both increasing dietary Fps:Cps and FA supplementation shifted ruminal volatile fatty acid (VFA) patterns toward more propionate and less acetate in goats. An interaction between dietary Fps:Cps and FA supplementation was observed for the ratio of acetate to propionate (A:P), which was more predominant when FA was supplemented in the low-Fps:Cps diet. Methane production was reduced by FA, and the reduction was larger in the low-Fps:Cps diet (31.72%) than in the high-Fps:Cps diet (17.91%). Fumaric acid decreased ruminal total VFA concentration and increased ruminal pH. No difference was found in ruminal DM degradation of concentrate or alfalfa hay by dietary Fps:Cps or FA. Goats presented a lower ruminal methanogen abundance with FA supplementation and a higher B. fibrisolvens abundance with high dietary Fps:Cps. Adjusting dietary Fps:Cps is an alternative dietary model for studying diet-dependent effects without changing dietary chemical composition. Fumaric acid supplementation in the low-Fps:Cps diet showed greater responses in methane mitigation and propionate increase.

  18. Intensification of biodiesel production from waste goat tallow using infrared radiation: Process evaluation through response surface methodology and artificial neural network

    Chakraborty, R.; Sahu, H.

    2014-01-01

    Highlights: • Enhanced and significantly accelerated biodiesel synthesis from waste goat tallow by infrared radiation. • In situ water removal by adsorbent profoundly promotes achieving high free fatty acids (FFAs) conversion. • Process optimization and parametric interaction-effects assessment by response surface method. • Artificial Neural Network Modeling for prediction of triglycerides and FFA conversion. • At optimal conditions, product biodiesel contains 98.5 wt.% FAME. - Abstract: For the first time, an efficient simultaneous trans/esterification process for biodiesel synthesis from waste goat tallow with considerable free fatty acids (FFAs) content has been explored employing an infrared radiation assisted reactor (IRAR). The impacts of methanol to tallow molar ratio, IRAR temperature and H 2 SO 4 concentration on goat tallow conversion were evaluated by response surface methodology (RSM). Under optimal conditions, 96.7% FFA conversion was achieved within 2.5 h at 59.93 wt.% H 2 SO 4 , 69.97 °C IRAR temperature and 31.88:1 methanol to tallow molar ratio. The experimental results were also modeled using artificial neural network (ANN) and marginal improvement in modeling efficiency was observed in comparison with RSM. The infrared radiation strategy could significantly accelerate the conversion process as demonstrated through a substantial reduction in reaction time compared to conventionally heated reactor while providing appreciably high biodiesel yield. Moreover, the in situ water removal using silica-gel adsorbent could also facilitate achieving higher FFA conversion to fatty acid methyl ester (FAME). Owing to the occurrence of simultaneous transesterification of triglycerides present in goat tallow, overall 98.5 wt.% FAME content was determined at optimal conditions in the product biodiesel which conformed to ASTM and EN biodiesel specifications

  19. Organic agricultural products in Europe and USA

    Skrodzka Violetta

    2017-12-01

    Full Text Available In the most developed countries of Western Europe and North America, the share of organic farming in the food market is between 2% and 6%. The share of organic products on the Polish food market is only 0.33% (Dryjańska E. 2017. The aim of this article is to compare organic agricultural products in the US and EU. The scope of the comparison was covered by the legal regulations for organic production in the mentioned regions and the availability of organic products for customers. In order to highlight differences between the organic product and their traditional counterpart, selected meta-analyzes were conducted by authors in the field of medical and natural sciences. The possibilities of buying organic products are described on the basis of personal experiences of the author as a consumer. The offer of organic products was analyzed on the example of one European country (Poland and the example of several states of America (Colorado, Virginia, New York. The rules for producing organic food in the US are more rigorous than in the EU. The offer of organic and conventional food targeted to the American consumer is comparable. Although Polish consumers have a positive perception of organic food, its supply is significantly different from the US market. The main differences are in distribution channels, product range, price and visual design of organic products.

  3. Milk production and physiological traits of ewes and goats housed indoor or grazing at different daily timing in summer

    Massimo Todaro

    2010-01-01

    Full Text Available During a 6 week trial in summer, 3 homogeneous groups, each consisting of 5 Comisana ewes and 5 Rossa Mediterranea goats, grazed watered forage resources during day (D or night (N, or were housed indoor and supplied with mowed herbage(H. Maximum THI peaked at 94 at the end of July, and was almost constantly higher of 80. Milk yield was higher in N than in D and H goats, whereas N ewes produced more milk than H group, but their milk yield was higher than D ewes only in the period with the highest THI values. The lower urea in N goat milk, and the higher casein in N ewe milk, seem to indicate a better efficiency in dietary nitrogen utilization of night grazing animals. N ewes showed lower SCC in milk, and higher incidence of clotting milk samples, in comparison to other ewes. N goats and ewes showed lower rectal temperature and pulse rate in the afternoon and, among metabolic parameters, higher hematic level of sodium. Night grazing was confirmed to be a management practice for increasing heat tolerance, to which goats appeared to be more sensitive in terms of milk yield.

  4. Spoilage potential of Pseudomonas species isolated from goat milk.

    2015-02-01

    Pseudomonas spp. are usually associated with spoilage microflora of dairy products due to their proteolytic potential. This is of particular concern for protein-based products, such as goat milk cheeses and fermented milks. Therefore, the goal of the present study was to characterize the proteolytic activity of Pseudomonas spp. isolated from goat milk. Goat milk samples (n=61) were obtained directly from bulk tanks on dairy goat farms (n=12), and subjected to a modified International Organization for Standardization (ISO) protocol to determine the number and proteolytic activity of Pseudomonas spp. Isolates (n=82) were obtained, identified by PCR, and subjected to pulsed-field gel electrophoresis with XbaI macro-restriction. Then, the isolates were subjected to PCR to detect the alkaline protease gene (apr), and phenotypic tests were performed to check proteolytic activity at 7°C, 25°C, and 35°C. Mean Pseudomonas spp. counts ranged from 2.9 to 4.8 log cfu/mL, and proteolytic Pseudomonas spp. counts ranged from 1.9 to 4.6 log cfu/mL. All isolates were confirmed to be Pseudomonas spp., and 41 were identified as Pseudomonas fluorescens, which clustered into 5 groups sharing approximately 82% similarity. Thirty-six isolates (46.9%) were positive for the apr gene; and 57 (69.5%) isolates presented proteolytic activity at 7°C, 82 (100%) at 25°C, and 64 (78%) at 35°C. The isolates were distributed ubiquitously in the goat farms, and no relationship among isolates was observed when the goat farms, presence of apr, pulsotypes, and proteolytic activity were taken into account. We demonstrated proteolytic activity of Pseudomonas spp. present in goat milk by phenotypic and genotypic tests and indicated their spoilage potential at distinct temperatures. Based on these findings and the ubiquity of Pseudomonas spp. in goat farm environments, proper monitoring and control of Pseudomonas spp. during production are critical.

    2013-02-01

    The aim of the study was to compare chemical composition and quality attributes of meat between male long fat tailed sheep (n = 17) and Small East African goats (n = 17) existing in Tanzania. Animals of 1.5 to 2 yrs in age and live body weight of 22.59±0.50 kg were purchased from livestock auction markets. Animals were fasted for 18 h and slaughtered according to standard halal procedure. Left carcasses were dissected into muscles, fat and bone and the muscle and fat were mixed together and chemically analysed. Meat quality attributes were measured based on Muscle longissimus thoracis et lumborum excised from right sides of carcasses. Goat carcasses had significant higher (p = 0.0302) moisture content (70.65% vs 66.96%) and lower (p = 0.0027) ether extract (2.49% vs 5.82%) than sheep but there was no significant species differences in protein and ash content. Sheep had lower (p = 0.0157) ultimate pH (5.74 vs 5.88) and higher (p = 0.0307) temperature (3.77°C vs 3.15°C) than goat carcasses. Sheep meat had lower (p = 0.0021) shear force values (29.83 N vs 34.07 N) than goat. Within species, at day 9 of ageing, meat tenderness improved (p = 0.0001) by 44.63% and 34.18% for sheep and goat. Pooled data showed that at d 9 of ageing, meat tenderness improved (p = 0.0001) by 39.25% (from 39.54 N to 24.02 N) compared to tenderness of meat which was not aged at day one of slaughter. The present study demonstrated the differences in chemical composition and quality attributes of meat existing between sheep and goats originated from East Africa.

    2012-12-01

    this new manure system we observed great decrease in the occurrence of typical confined kids diseases, like diarrhea, pneumonia and omphalophlebitis, and lower overall mortality rate until slaughter when compared with goats reared in pens with dirt and litter. The investment for installation of the system was assessed $ 722.50 (U.S. $ 48.16/m². Considering the potential use of the stall, placing 10 adult animals (1.5 m²/head, with average production of the adult animal of 600 kg of manure/year, can be obtained easily, 6000 kg of manure, with average price of $ 0.13/kg., which could revert to $ 780.00/production cycle, this feature would pay the investment in about two years. In order to improve the investment cost it can be used in the construction of treated pine wooden pallets, in view of durability, ease of working wood and the lowest price. In order to facilitate a return on investment, can be treated pine used in the construction of wooden pallets, in view of its durability, workability and lower price, which can replace other more expensive types of wood, with the same efficiency and advantage of being lighter, which facilitates the management and operational cleaning of pallets. Furthermore, the capture system can be strong allies on the aggregation of producers of small ruminants, increasing the production of humus, energy source for anaerobic digesters, manure crops and organic manure use in integrated agriculture systems, pastures and forest. The validated system made possible the manpower needed to maintain the stall tested, improving the management and performance of goats, other income generating activities for productive and sustainable.

    The study evaluated replacement of Egyptian berseem clover (BC, Trifolium alexandrinum) with spent rice straw (SRS) of Pleurotus ostreatus basidiomycete in diets of lactating Baladi goats. Nine lactating homo-parity Baladi goats (average BW 23.8±0.4 kg) at 7 d postpartum were used in a triplicate 3×3 Latin square design with 30 d experimental periods. Goats were fed a basal diet containing 0 (Control), 0.25 (SRS25) and 0.45 (SRS45) (w/w, DM basis) of SRS. The Control diet was berseem clover and concentrate mixture (1:1 DM basis). The SRS45 had lowered total feed intake and forages intake compared to Control. The SRS25 and SRS45 rations had the highest digestibilities of DM (p = 0.0241) and hemicellulose (p = 0.0021) compared to Control which had higher (p<0.01) digestibilities of OM (p = 0.0002) and CP (p = 0.0005) than SRS25 and SRS45. Ruminal pH and microbial protein synthesis were higher (p<0.0001) for SRS25 and SRS45 than Control, which also had the highest (p<0.0001) concentration of TVFA, total proteins, non-protein N, and ammonia-N. All values of serum constituents were within normal ranges. The Control ration had higher serum globulin (p = 0.0148), creatinine (p = 0.0150), glucose (p = 0.0002) and cholesterol (p = 0.0016). Both Control and SRS25 groups had the highest (p<0.05) milk (p = 0.0330) and energy corrected milk (p = 0.0290) yields. Fat content was higher (p = 0.0373) with SRS45 and SRS25 groups compared with Control. Replacement of BC with SRS in goat rations increased milk levels of conjugated linoleic acid and unsaturated fatty acids compared with Control. It was concluded that replacing 50% of Egyptian berseem clover with SRS in goat rations improved their productive performance without marked effects on metabolic indicators health.

    Aboulnaga, A.I.; Kamal, T.H.; Abusinna, G.; Amer, M.M.

    1992-01-01

    Nine lactating baladi goats (2.5 years old and 17 Kg b. wt.) were maintained in the climatic chamber for 3 successive experimental periods of 7 days each. The first was mild climate exposure (15 - 20 degree C and 50 - 25% R.H.) . The second was heat exposure of 35 degree C and 25% R.H. from 7 a.m. to 15 p.m. and about 20 degree C and 28% R.H. during the remaining 16 hours. The third was the same previous hot climate exposure but the goats were injected daily with 30 mg/Kg B.wt./day with metamizol ( novalgin ) . Under heat stress conditions, goats injected with novalgin tended to restore the heat-induced changes in most biological parameters studied to their initial levels. There were significant increases in RBC; plasma T 4 , Na, Ca, P, Mg, and cholesterol; body weight ( B.wt. ), milk yield ( M.Y.) and significant decreases in rectal temperature (RT), respiration rate (RR) and pulse rate (PR), as compared with the corresponding parameters of the same heat-stressed goats prior to novalgin administration.1 tab

    Full Text Available The aim of the pilot study was to evaluate slaughter characteristics and carcass composition of indigenous long fat tailed sheep and Small East African goats purchased from the auction markets slaughtered at 1.5 to 2 yrs of age and 20 kg to 25 kg live weight. The animals were slaughtered according to halal standard procedures. The left half carcasses were jointed into eight wholesale joints, and dissected into muscles, fat and bone, which were weighed separately. Sheep had greater (p<0.05 slaughter BW (22.29 kg vs 20.50 kg and empty BW (20.17 kg vs 18.67 kg than goats (p<0.05. Dressing percentages were lower (p<0.001 in sheep than goats when carcass weight was expressed as percentage of slaughter BW (42.31% and 47.15% and empty BW (46.75% and 51.79%. Sheep carcasses had lower (p<0.001 proportion (66.18% vs 71.64% of muscles and higher (p<0.001 proportion of fat (7.41% vs 3.44% than goat carcasses. Sheep had proportionally lighter (p<0.001 shoulder (18.89% vs 22.68% and heavier (p<0.05 proportion of chump (7.916% vs 6.76% and main rib (8.12% vs 7.07%. Sheep had more (p<0.001 muscles in the leg (28.83% vs 27.08% and main rib (7.62% vs 6.36% than goats. Sheep had less (p<0.001 muscles (20.28% vs 23.56% in shoulder joints when expressed as percentage of total muscle of carcasses. It is concluded that there are differences in sheep and goat both in terms of carcass and joint yields and composition. The present study also implies that there is need to consider setting different meat cuts and prices for these cuts when one takes into account the differences in muscle distribution within joints in sheep and goats.

    2011-07-01

    Growth, carcass quality, and meat quality data from Murciano-Granadina kids (n=61) raised under three different systems were collected. Canonical discriminatory analysis and cluster analysis of the entire meat production process and its stages were performed using the rearing systems as grouping criteria. All comparisons resulted in significant differences and indicated the existence of three products with different quality characteristics as a result of the three rearing systems. Differences among groups were greater when comparing carcass and meat qualities as compared with growth differences. The paired analyses of canonical correlations among groups of variables integrated in growth, carcass and meat quality, resulted in all being statistically significant, pointing out the canonical correlation coefficient between carcass quality and meat quality.

    for conventional production into land for organic production, a period of two years must pass before the land being transformed can be used for organic production. During that time, the land is counted as land of the organic industry, but it can only produce the conventional product. To handle this rule, we make......Concerns about the impact of modern agriculture on the environment have in recent years led to an interest in supporting the development of organic farming. In addition to environmental benefits, the aim is to encourage the provision of other “multifunctional” properties of organic farming...... such as rural amenities and rural development that are spillover benefit additional to the supply of food. In this paper we further develop an existing dynamic general equilibrium model of the Danish economy to specifically incorporate organic farming. In the model and input-output data each primary...

    Full Text Available The Caprine Arthritis Encephalitis (CAE is a disease who cause considerable economic losses, including loss in the milk production and reduction of the useful life of the animal. In the diagnosis of this disease the agar gel immunodifusion test (AGID is used worldwide as the selection test. The objective of thid work was to test three different concentrations of bovine fetal serum (BFS in the production of the antigen (Ag for the diagnosis of the CAE virus (CAEV, to verify amongst the three methods the most efficient concentration and which the antigen concentration of the antigen produced is appropriate for the test. The method of the AMICON and the concentration of the Ag for dialysis was indicated, however the system AMICON, despite the implantation costs, promoted minor loss of antigen, little time expense in the processing and greater simplicity. With relation to the amount of BFS placed after the viral inoculation it was verified that 5% of BFS the amount that presented better resulted. The antigen concentration 100 times was more indicated, therefore it allowed the diagnosis of the CAEV for two proteins (gp 135 and p28. The concentration of the Ag for precipitation/ultracentrifugation, used for imunoenzimatic tests, did not present resulted satisfactory used in the AGID.

    Sheeppox and goatpox outbreaks occur often in India incurring huge economic loss to the small ruminant industry. This paper describes two sheeppox outbreaks, of which one occurred in an organized sheep breeding farm at Makhdoom (Uttar Pradesh), India, during 2007 and another in goats at the Central Institute of Research on Goats, Makhdoom (Uttar Pradesh), India during 2008. In the first outbreak, a local Muzaffarnagari sheep breed was affected (n=477) with morbidity and mortality rates, respectively, of 100% and 53.9% accompanied by significant productivity losses. In the 2008 outbreaks, a small number of goats were affected without any mortality. The tissue and swabs collected from both the outbreaks were processed and inoculated onto Vero cells, and the causative agent of the outbreaks, capripox virus (CaPV), was isolated. The identity of the virus was confirmed as CaPV based on electron microscopy, experimental pathogenesis in sheep, capripox-specific conventional and real-time PCRs. Sequence analysis of the P32 envelope protein gene revealed that the causative agent of both outbreaks was confirmed as sheeppox virus (SPPV) implying SPPV infection not only in sheep but also goats in India. © 2010 Blackwell Verlag GmbH.

    Full Text Available One of the major current challenges in the livestock industry is meeting the demand for livestock products of a growing world population. Bio-economic models integrate animal biology and rural enterprise management, which allows for the study of complex animal production systems. This paper aims at simulating the productive performance of a herd grazing under different management conditions. To do so, a simple simulation model of a goat herd (MSSRC, rangeland forage growth, and the dynamics of animal population in the semi-arid region of Southwestern Tamaulipas under three rainfall scenarios (300, 500, and 700 mm. of average annual precipitation was built. The objective was to evaluate the sustainability of extensive grazing under different animal loads. Nine different scenarios were evaluated, corresponding to the different combinations of the three rainfall scenarios and three levels of initial loads (Hi and nannies maximum load (HMAX. Evaluated variables are: kids sales (C; total number of nannies (female goats, HT; sales of replacement nannies (VREE; sales of scrap goats (CDS; rangeland condition (CA; voluntary consumption (CV; mortality rate (M; abortion rate (A;  and average annual profits (UPA. Simulation was performed on a 1,000 hectares plot, and three 10-year periods were used as time framework. Analysis of Variance (ANOVA revealed statistically significant (P < 0.05 differences between scenarios for all studied variables. Biomass primary net production under the 300, 500, and 700 mm of rainfall was found to be 1,132.2 ± 362.9, 2,244.2 ± 517.0, and 3,113.3 ± 598.7 kg DM ha-1 per year, and the average annual production of kids was 36 ± 17, 90 ± 31, and 132 ±37, respectively. The low loads scenarios showed a stable behavior, with a constant rate of kids production over the three simulation periods (0-30 years, which resulted in a higher average annual profit, and a more sustainable profile than those with heavier

    2009-06-01

    Full Text Available Abstract Leadership development has been a primary objective of Extension educators directing Ohio Meat Goat Task Force efforts. Producer members have been instrumental in the formation of the Ohio Meat Goat Marketing Alliance. This group has developed by-laws and articles of incorporation for the purpose of promoting and marketing commercial meat goat producers in Ohio. Nationwide market centers have been accessed through the establishment of graded pool sales. Cooperation between producer networks, industry, and the Department of Agriculture were responsible for establishing a certified livestock grader position. Producers have enhanced the effectiveness of their efforts by partnering with agencies such as the Ohio Cooperative Development Center, Somalia and East African Organization, Jewish Family Services and Institute for Social and Economic Development. Extension educators have developed the Ohio Meat Goat Production and Budgeting Fact Sheet as a guide for establishing this value added enterprise. Extension has designed and conducted regional workshops, seminars, and on-farm tours to transfer knowledge to over 2100 participants. Education, production, and marketing topics are discussed in the Buckeye Meat Goat Newsletter. The website http://www.ohiomarketgoat.com has been developed to enhance the exchange of production and marketing information. The task force has received $63,000 in Research and Extension grants to conduct on going feasibility studies of ethnic markets, Ohio’s processing infrastructure, and development of farmer/consumer cooperatives. On-farm meat goat research encompasses breed comparisons, forage utilization, and developing benchmark data. Progress continues in the ability to market fresh and safe chevon products directly to emerging ethnic and faith based consumer populations to capture the most value. This task force is taking a unique approach to building industry infrastructure by utilizing a social approach

    Full Text Available The article presents an outline of the issue concerning formulation of a marketing strategy and the possibility of using the knowledge on consumers' preferences for organic development of farms and their products on the example of southern Poland. The paper analyses the distribution process of organic food in the aspect of developing innovative marketing strategies. The studies were performed in 50 organic farms and on the example of 100 respondents from the region of southern Poland. In the opinion of the surveyed representatives of the organic food producers, a competitive advantage of their offer depends the most on the health values, brand, reputation, and taste. Moreover, information on products and the form and place of their sale are significant. The analysis shows that the knowledge is the most eagerly obtained from the Internet. Thus, producers should publish their profiles and pages on social media and business portals.

  14. Biogas and bioethanol production in organic farming

    Oleskowicz-Popiel, P

    2010-08-15

    The consumer demand for environmentally friendly, chemical free and healthy products, as well as concern regarding industrial agriculture's effect on the environment has led to a significant growth of organic farming. On the other hand, organic farmers are becoming interested in direct on-farm energy production which would lead them to independency from fossil fuels and decrease the greenhouse gas emissions from the farm. In the presented work, the idea of biogas and bioenergy production at the organic farm is investigated. This thesis is devoted to evaluate such a possibility, starting from the characterization of raw materials, through optimizing new processes and solutions and finally evaluating the whole on-farm biorefinery concept with the help of a simulation software.

    2012-10-01

    Corynebacterium pseudotuberculosis is the causative agent of caseous lymphadenitis (CL), a chronic debilitating disease of goats. In the present study, a total of 575 goats of Sirohi breed on an organized farm situated in the semi-arid tropical region of Rajasthan, India were clinically examined. Pus samples from superficial lymph nodes of 27 (4.7%) adult goats presenting clinical lesions suggestive of CL were collected for bacteriological and molecular analyses. Of these goats, 51.9% yielded C. pseudotuberculosis on the basis of morphological, cultural and biochemical characteristics. A polymerase chain reaction (PCR) assay targeting proline iminopeptidase gene specific to C. pseudotuberculosis was developed that confirmed all 14 bacterial isolates. The specificity of the PCR product was confirmed by sequencing of the 551-bp amplicon in both senses, showing 98-100% homology with published sequences. Thus, overall prevalence rate based on clinical, bacterial culture and PCR assay were found to be 4.7%, 2.4% and 2.4%, respectively. The PCR assay developed in this study was found to be specific and rapid, and could be used for confirmation of CL in goats as an alternative method to generally cumbersome, time-consuming and less reliable conventional methods.

  3. Health and Welfare in Organic Poultry Production

    Berg C

    2002-03-01

    Full Text Available This review paper deals with the major health and welfare aspects of organic poultry production. The differences between organic and conventional egg and poultry meat production are discussed, with the main emphasis on housing and management requirements, feed composition and the use of veterinary prophylactic and therapeutic drugs. The effects of the legislation and statutes for organic farming on the health and welfare of the birds are also discussed, especially in relation to the biosecurity problems associated with free-range systems, the occurrence of behavioural disturbances in loose housed flocks and the use of veterinary drugs and vaccinations in general. The results from a questionnaire sent out to all Swedish organic egg producers, where questions about the farmer's perception of the birds' health status were included, are presented at the end of the paper. It is concluded that most of the health and welfare problems seen in conventional poultry systems for loose housed or free ranging birds can also been found on organic poultry farms. It is also concluded that there is a need for information about biosecurity, disease detection and disease prevention on organic poultry farms.

    Full Text Available Normal 0 21 false false false MicrosoftInternetExplorer4 The market of organic products around the world increased its volume in Central and Eastern Europe with organic food market has a number of shared features, which include the relatively low demand for organic food, low share of regular customers, the problems of producers marketing, the lack of enterprises which process organic products. Consumer behavior purchasing organic foods is influenced by several factors, among which is dominated consumer personality, income, finances and lifestyle, as well as psychological factors such as perception, motivation, learning, cognition and attitudes. Cultural and social factors in consumer behavior exhibit a lesser degree. Organic fruit and organic vegetables quality is generally higher for content of biologically active substances such as vitamins, polyphenols and flavonoids. The content of pesticide residues in organic food is significantly lower than conventional production. Regular monitoring of chemical and microbiological safety of organic products already in the primary production occurring in the raw state and after working in various sectors of food, an intensification of awareness raising and targeted increased support for organic agriculture. Multifunctional sector and increased support for family farms oriented for sectors with higher added value than the home sale, production processing on the farm and so on. By support of the sale of high quality domestic production by the state will be possible to persuade more people to personal health status and greater consumption of organic food  affects the health and prevent the occurrence of various diseases.doi:10.5219/96  

  7. Tunnel production enhances quality in organic carrot seed production

    Deleuran, L C; Boelt, B

    2009-01-01

    production of open-pollinated carrot varieties increased the yield and germination percentages when compared with normal field conditions. Yield was in the range of 100-250 g and 2-17 g seeds m-2 respectively, and germination percentage was 84-95 and 43-55, respectively. However, hybrid carrot seed...... production showed lower yields than did their open-pollinated counterparts. Yields ranging from 60-123 g seeds m-2 can be obtained, but the production needs to be carefully planned and monitored. Different growing systems in tunnels have been studied in both open-pollinated and hybrid carrot (Daucus carota L......In Denmark, organic vegetable seed production is possible for some of the late-maturing species when the maturing is performed in lightweight tunnels which are also relevant for the isolation of small-scale production. The tunnel system offers several advantages, e.g., it is possible to control...

  8. Modelling the behaviour of organic degradation products

    Cross, J.E.; Ewart, F.T.; Greenfield, B.F.

    1989-03-01

    Results are presented from recent studies at Harwell which show that the degradation products which are formed when certain organic waste materials are exposed to the alkaline conditions typical of a cementitious environment, can enhance the solubility of plutonium, even at pH values as high as 12, by significant factors. Characterisation of the degradation products has been undertaken but the solubility enhancement does not appear to be related to the concentration of any of the major organic species that have been identified in the solutions. While it has not been possible to identify by analysis the organic ligand responsible for the increased solubility of plutonium, the behaviour of D-Saccharic acid does approach the behaviour of the degradation products. The PHREEQE code has been used to simulate the solubility of plutonium in the presence of D-Saccharic acid and other model degradation products, in order to explain the solubility enhancement. The extrapolation of the experimental conditions to the repository is the major objective, but in this work the ability of a model to predict the behaviour of plutonium over a range of experimental conditions has been tested.

  9. Postharvest Practices for Organically Grown Products

    Ilić Zoran S.

    2018-03-01

    Full Text Available Quality of produce cannot be improved after harvest, only maintained. Postharvest handling depends on the specific conditions of production, season, method of handling, and distance to market. Under organic production, growers harvest and market their produce at or near the peak ripeness more commonly than in many conventional systems. Organic production often includes more specialty varieties whose shelf life and shipping traits are reduced or even inherently poor. Harvesting and handling techniques that minimize injury to the commodity, as well as increased care with field and packinghouse sanitation, (chlorine, ozone, calcium hypochlorite, sodium hypochlorite and chlorine dioxide, acetic acid, peroxyacetic acid, vinegar, ethyl alcohol, hydrogen peroxide, etc. during postharvest processes are vital components of a postharvest management plan for organic products. Sodium carbonate, sodium bicarbonate, and physical treatments such as heat treatments (as hot water treatment or dips, short hot water rinsing and brushing or hot air can significantly lower the disease pressure on the harvested commodities. These sanitation practices are very easy to implement in the organic food production chain. They start in the field and continue during harvesting, sorting, packing, and transportation and continue even in the consumer’s home. All those treatments reduce rot development, provide quarantine security, and preserve fruit quality during cold storage and shelf life. In addition, the use chitosan, propolis, methyl jasmonate, essential oils, carnuba wax, biocontrol agents and modified atmosphere packaging can also reduce decay development during prolonged storage. All these treatments can be applied alone or in combination with each other in order to improve decay control after harvest and provide a healthy and safe product to the consumer. The aim of this chapter is to shed more light on the latest information on permitted treatments for organic

    Ornella Corazza

    2014-01-01

    Full Text Available Introduction. The use of unlicensed food and herbal supplements to enhance sexual functions is drastically increasing. This phenomenon, combined with the availability of these products over the Internet, represents a challenge from a clinical and a public health perspective. Methods. A comprehensive multilingual assessment of websites, drug fora, and other online resources was carried out between February and July 2013 with exploratory qualitative searches including 203 websites. Additional searches were conducted using the Global Public Health Intelligence Network (GPHIN. Once the active constitutes of the products were identified, a comprehensive literature search was carried out using PsycInfo and PubMed. Results. The most common sexual enhancement products available on the Internet were identified. Their active ingredients included yohimbine, maca, horny goat weed and Ginkgo biloba. These four substances were reported with the occurrence of adverse events and the induction of psychological symptoms, such as mood changes, anxiety, and hallucinations as well as addictive behaviours. Conclusions. Uncontrolled availability of sexual enhancement products that contain potentially harmful substances is a major public health concern. The possible impact on population health, particularly among subjects with psychiatric disorders, usually at risk for sexual dysfunction, may be significant. This new trend needs to be extensively studied and monitored.

  11. Cow's milk and goat's milk.

    Turck, Dominique

    2013-01-01

    Cow's milk is increasingly suggested to play a role in the development of chronic degenerative, non-communicable disorders whereas goat's milk is advocated as having several health benefits. Cow's milk is a rich and cheap source of protein and calcium, and a valuable food for bone health. Despite their high content in saturated fats, consumption of full-fat dairy products does not seem to cause significant changes in cardiovascular disease risk variables. Early introduction of cow's milk is a strong negative determinant of iron status. Unmodified cow's milk does not meet nutritional requirements of infants although it is acceptable to add small volumes of cow's milk to complementary foods. Cow's milk protein allergy has a prevalence ranging from 2 to 7%, and the age of recovery is usually around 2-3 years. The evidence linking cow's milk intake to a later risk of type 1 diabetes or chronic degenerative, non-communicable disorders (obesity, metabolic syndrome, type 2 diabetes, hypertension) is not convincing. Milk probably protects against colorectal cancer, diets high in calcium are a probable cause of prostate cancer, and there is limited evidence suggesting that high consumption of milk and dairy products increases the risk for prostate cancer. There is no evidence to support the use of a cow's milk-free diet as a primary treatment for individuals with autistic spectrum disorders. Unmodified goat's milk is not suitable for infants because of the high protein and minerals content and of a low folate content. Goat's milk has no clear nutritional advantage over cow's milk and is not less allergenic. The European Food Safety Authority recently stated that proteins from goat's milk can be suitable as a protein source for infant and follow-on formula, provided the final product complies with the compositional criteria laid down in Directive 2006/141/EC.

    A. Gaviraghi

    2011-03-01

    Full Text Available Summering on alpine pastures from June to October has long been the traditional management of goat flocks in the mountain areas of Lombardy. At present most of the 50.000 goats farmed in Lombardy are still summered, even though only a few thousands - belonging to local breed - are regularly milked. For these goats summering appears to be fundamental not only to allow milk production but also to restore body reserves. The increasing interest in commercial goat milk production in Lombardy involves mainly intensive farming with zero or minimum grazing. However, semi-extensive goat milk production, including summering, could respond to social and environmental goals (Citterio et al., 2002 being able to exploit some economic opportunities...

    2017-01-01

    Domestic goats are raised for meat, milk and hair production, in herds for rangeland weed control, and as pack animals. Domestic sheep, goats and wild bighorn sheep are all susceptible to a multifactorial pneumonia. We sampled 43 herd goats from 7 herds and 48 pack goats from 11 herds for viral and bacterial serology, parasitology, and Pasteurellaceae microbiology. The goats in this study were in generally good health, although most goats did harbor various pathogens and parasites including several bacteria, specifically Pasteurellaceae, which have been associated with pneumonia in free-ranging bighorn sheep. It is not known if domestic goats can transmit the Pasteurellaceae or other pathogens found in this study readily to wild bighorn sheep. However, due the possibility of transmission, domestic goats in areas in or near bighorn sheep habitat should be managed to minimize the risk of spreading disease agents to bighorn sheep.

It is not known if domestic goats can transmit the Pasteurellaceae or other pathogens found in this study readily to wild bighorn sheep. However, due the possibility of transmission, domestic goats in areas in or near bighorn sheep habitat should be managed to minimize the risk of spreading disease agents to bighorn sheep.

    Domestic goats are raised for meat, milk and hair production, in herds for rangeland weed control, and as pack animals. Domestic sheep, goats and wild bighorn sheep are all susceptible to a multifactorial pneumonia. We sampled 43 herd goats from 7 herds and 48 pack goats from 11 herds for viral and bacterial serology, parasitology, and Pasteurellaceae microbiology. The goats in this study were in generally good health, although most goats did harbor various pathogens and parasites including several bacteria, specifically Pasteurellaceae, which have been associated with pneumonia in free-ranging bighorn sheep. It is not known if domestic goats can transmit the Pasteurellaceae or other pathogens found in this study readily to wild bighorn sheep. However, due the possibility of transmission, domestic goats in areas in or near bighorn sheep habitat should be managed to minimize the risk of spreading disease agents to bighorn sheep.

    Full Text Available Functional foods represented an important element of a balanced, healthy diet. They play an important role in improving the structure of the diet of the population, are a means of prevention, correction and prevention of early transition premorbid conditions and various diseases. Meat and meat products based on it can be considered as a promising raw material for functional foods. Goat has certain dietary properties and can be used in manufacturing, but the production of high-grade products from goat meat, capable of long-term storage is not well developed. The chemical composition of the new raw meat - goat meat, on the example of the longissimus muscle of back is rich in protein, moisture, ash, and low-fat compared with other types of raw meat, which lets you create based on goat meat sector wide functional meat products. Therefore investigated the possibility of using goat meat in the production technology of functional foods. Showing the prospects for the development of goat in Russia. Investigated character of autolysis goat meat electro-physical methods and histological analysis. In the process of autolysis of goat meat are changing the electrical properties of raw meat, which are correlated with the morphological characteristics. Basic autolytic changes occurring in muscle tissue in the early stages of ripening, were reduced to a small extent the political process involving varying degrees of muscle structure in the early stages. In the later stages of maturation revealed changing widespread. Revealed that autolysis has characteristic periods and develops within 12 hours, further changes are irreversible. Shows the change in pH, carbohydrate fractions in the longissimus muscle of back goat. Results of the study of dynamics of change in pH, carbohydrate fractions in the longissimus muscle of back goat show compliance with the laws of classical autolysis noted in other sources, but differ in the time period.

    Tests were carried out to determine the effect of manufacturing procedures for a Camembert-type cheese from raw goats' milk on the growth and survival of Staphylococcus aureus organisms added to milk at the start of the process, and to study the possible presence of staphylococcal enterotoxin A in these cheeses. The initial staphylococcal counts were, respectively, 2, 3, 4, 5 and 6 log cfu ml-1. Cheese was prepared following the industrial specifications and ripened for 41 d. Detection of enterotoxins was done by the Vidas SET test and by an indirect double-sandwich ELISA technique using antienterotoxin monoclonal antibodies. Generally, numbers of microbes increased at a similar rate during manufacture in all cheeses until salting. During the ripening period, the aerobic plate count population and Staph. aureus levels remained stable and high. There was an approximately 1 log reduction of Staph. aureus in cheeses made with an initial inoculum of Staph. aureus greater than 10(3) cfu ml-1 at the end of the ripening period (41 d) compared with the count at 22 h. The level of staphylococcal enterotoxin A recovered varied from 1 to 3.2 ng g-1 of cheese made with an initial population of 10(3)-10(6) cfu ml-1. No trace of enterotoxin A was detected in cheeses made with the lowest Staph. aureus inoculum used in this study.

  8. Evaluation of targeted drenching using Famacha method in Creole goat: reduction of anthelmintic use, and effects on kid production and pasture contamination.

    2007-05-15

    Haemonchus infection was monitored for 2 years (six kidding periods) in a Creole goat flock grazing under oceanic-tropical climate. Two hundred and thirty individual does were involved from late pregnancy to weaning. Anaemia diagnoses using Famacha method and packed cell volume (PCV) were compared. The best agreement (Kappa=0.33) was found if anaemia was declared when PCV values fell to 16 or below and Famacha score was 4 or 5. Drenching policy according to Famacha method was compared to systematic drenching policy. Using the Famacha method allowed a dramatic decrease in anthelmintic use during the periparturient period (0.57 individual dose instead of three doses for the control). The proportion of the nematode population on the pasture not derived from previously-treated goats (in refugia) was estimated to about 79% (65-90%) of the pasture contamination derived from the Famacha group. On the average, goats which needed to be drenched produced less than the control or undrenched goats (kid average daily gain was decreased by about 15%). The repeatability of the need for drenching individual does was estimated to 0.41. The older goats or the goats in poorer body condition at kidding needed more drenching than the younger animals and the animals in good body condition. Consequently the Famacha method may be used as an additional tool for the culling management.

  9. Organic vs. Non-Organic Food Products: Credence and Price Competition

    Yi Wang

    2017-04-01

    Full Text Available We analyze the organic and non-organic production choices of two firms by considering customers’ trust in organic food products. In the context of customers’ possible willingness to pay a premium price and their mistrust in organic food products, two firms first make choices on offering organic and non-organic food products. If offering organic products, a firm can further invest in the credence system to increase customers’ trust in their organic products. At the final stage, two firms determine prices. We provide serval insights. First, we characterize the market conditions in which only one firm, both firms or neither firm will choose to offer organic food products. We find that the higher the production costs or credence investment costs for organic food products are, the more likely firms are to choose to produce non-organic food products. Second, if it is expensive enough to invest in organic credence, offering organic food products may still be uncompetitive, even if organic production cost appears to have no disadvantage compared to non-organic food products. Third, we highlight how the prices of organic food products in equilibrium are affected by market parameters. We show that when only one firm offers organic food products, this firm tends to offer a relatively low price if organic credence investment is expensive. Fourth, we highlight how one firm’s credence investment decision in equilibrium can be affected by the product type choice of the other firm. We find that the investment in organic credence is lower when both firms offer organic food products compared with the case when only one firm offers organic food products.

  12. Genetic characterization of Istrian goat: the key-point for a long-term conservation

    Ante Ivanković

    Full Text Available Istrian goat is an autochthonous Croatian breed which inhabited Istrian peninsula and was important in milk production and human nutrition, especially for poor people. For centuries Istrian goat was a recognizable heraldic symbol of Istria, but in her real form almost disappeared from the breeding area. The revitalization and reaffirmation of Istrian goat began with several dozen remaining breeding animals, after a decade-long breeding ban. Genetic characterization of the Istrian goat population is necessary for providing insight into the state of genetically preserved structure within population as well as positioning Istrian goats within phylogenetically related breeds. Microsatellite and mtDNA analysis of reproductive individuals of Istrian goat and related breeds, Croatian White goat and Saanen goat was carried out. In the population of Istrian goat, higher allelic variability (nA = 9.7; AR = 7.4 were found as well as significant genetic distance (FST = 0.068 - 0.086 in relation to other two breeds. Such results indicated that Istrian goat constitutes a separate genetic identity. The observed ten haplotype sequences of the D-loop mtDNA also confirm the significant genetic richness of the maternal hereditary component. The observed haplotypes in the population of Istrian goat belong to lineage A. A smaller number of haplotypes shows similarity to the group of “white” goats, indicating traces of earlier limited but targeted crossing of Istrian goats. The genetic profile analysis of Istrian goats indicates a high level of genetic variability and provides guidelines for a long-term conservation program. The preserved genetic and promising potential of milk production of Istrian goat makes a significant basis for her economic reaffirmation. Orientation of the breed towards milk production could be an efficient strategy for its effective preservation.

    2015-01-01

    The present study assessed the accumulation of selected heavy metals (Cd, Cr, Pb and Cu) indifferent organs including brain, heart, lungs, liver, stomach, kidney and flesh (muscles) of several animals commercially available in the market of Lahore, Pakistan. The concentrations found in different organs of chicken, goat and cow ranged between 0.132-2.165 mg/g for Cd, 0.768-2.335 mg/g for Cr, 0.260-1.411 mg/g for Pb and 0.092-1.195 mg/g for Cu. In the absence of national safety standards in respect to the content of heavy metals in foodstuffs, the results obtained were compared with international guidelines and found concentrations considerably higher than the prescribed safe limits. Therefore, immediate attention must be paid to prevent public health risks associated with the presence of toxic heavy metals in the commercially available meat products. (author)

    Organic livestock farming is based on a low input production method, aiming to provide products of a high product and process quality rather than maximizing production. The production of a high meat quality corresponds to the expectations of consumers who are both seeking a premium product and who are willing to pay premium prices. This review focuses on the question of whether organic pork and beef production currently meet consumer demands, and it elaborates the potentials and limitations f...

  20. Production and organization of neocortical interneurons

    Khadeejah T Sultan

    2013-11-01

    Full Text Available Inhibitory GABA (γ-aminobutyric acid-ergic interneurons are a vital component of the neocortex responsible for shaping its output through a variety of inhibitions. Consisting of many flavors, interneuron subtypes are predominantly defined by their morphological, physiological, and neurochemical properties that help to determine their functional role within the neocortex. During development, these cells are born in the subpallium where they then tangentially migrate over long distances before being radially positioned to their final location in the cortical laminae. As development progresses into adolescence, these cells mature and form chemical and electrical connections with both glutamatergic excitatory neurons and other interneurons ultimately establishing the cortical network. The production, migration, and organization of these cells are determined by vast array of extrinsic and intrinsic factors that work in concert in order to assemble a proper functioning cortical inhibitory network. Failure of these cells to undergo these processes results in abnormal positioning and cortical function. In humans, this can bring about several neurological disorders including schizophrenia, epilepsy and autism spectrum disorders. In this article, we will review previous literature that has revealed the framework for interneuron neurogenesis and migratory behavior as well as discuss recent findings that aim to elucidate the spatial and functional organization of interneurons within the neocortex.

    2007-04-01

    Full Text Available In Croatia, goats are primarily bred for meat production. However, for the past twenty years the interest in goat milk production was based on imported breeds such as Alpine-French, Saanen and German Improved Fawn goat. The purpose of this paper is to establish litter size of the principal goat breeds in Croatia and the indicators related to milk yield and chemical composition. The largest average litter size has been determined on the German Improved Fawn (1.72, then with the Boer (1.54, the Saanen (1.53 and the Croatian coloured goat (1.51, while the Alpine-French goat was the smallest (1.31. The longest lactation period (259 days has been determined on the Alpine-French goat, while the largest milk yield during lactation (724.4 kg and the largest milk fat yield (20.16 kg and protein yield (18.64 kg have been determined on the Saanen goat. However, it has been established that the Alpine-French goat milk has the highest average fat content (3.55 %, while the German Improved Fawn’s milk has the highest protein content (3.23 %. The Saanen goat had the longest milking period (222 days and the shortest suckling period (32 days, while the Alpine-French and the German Improved Fawn had the longest suckling period (51 and 45 days, respectively. The lowest quantity of milk during the suckling period (102.97 kg, i.e. 14 % was suckled by Saanen kids, while the Alpine-French (122.08 kg, i.e. 22 % and the German Improved Fawn kids suckled the greatest quantity (116.31 kg, i.e. 22 %.

    2009-06-01

    Full Text Available Six focus groups were conducted with each having ten people who attend different Islamic Centers in Ohio. The objective of the focus groups was to understand Halal meat purchase patterns and consumption patterns of the Moslem population with special attention to goat. The Ohio State University Extension personnel are utilizing these results to work with meat goat producers to understand and meet the requirements of the Halal meat market.  Participants discussed the Zabiha approach to slaughtering animals as the most merciful by causing the least pain. Many participants noted they had no way of knowing where the animal  came from and this held tremendous concerns relative to the feeding of animal by-products, use of hormones, and adulteration with pork. These trust concerns led to decisions about where to purchase their meat with 72% purchasing from a Moslem owned retail store. Only 13% purchased from a large grocery and 8% direct from a farmer.   Participants indicated their consumption patterns according to weekly, seasonal, and holiday use in addition to variations according to their personal geographic origin. The average meat purchase was 23 pounds with an average occurrence of 12.5 times per annum.  Purchasing trends indicated that 78% prefer lean over marbled cuts. Nearly 86% prefer fresh over frozen goat meat and nearly a third responded that they would pay more for fresh. Intact males were preferred by 42% of the respondents. Preferences for meat goat cuts were: Leg (71%, Chops (42%, Shoulder (24%, Breast (7%. Nearly a third indicated they also want the kidneys, heart, or head. Demographic shifts in the United States indicate that there are almost 53 million people who have a preference for goat meat. There are 2.4 million goats in the US according to the 2007 Agricultural Statistics. Based on consumption trends of this study, goat demand exceeds inventory by 160%. Meat goat consumer trends are changing regarding

  3. Body live weight and milk production parameters in the Majorera and Palmera goat breeds from the Canary Islands: influence of weight loss.

    Seasonal weight loss (SWL), caused by poor quality pastures during the dry season, is the major limitation to animal production in the tropics. One of the ways to counter this problem is to breed animals that show tolerance to SWL. The objective of this study was to understand the effect of feed restriction in milk production and live weight (LW) evolution in two goat breeds, with different levels of adaptation to nutritional stress: the Majorera (considered to be tolerant) and the Palmera (considered to be susceptible). A total of ten animals per breed were used. Animals were divided in four groups (two for each breed): a restricted group (restricted diet) and a control group. LW and milk yield parameters were recorded through a trial that lasted 23 days in total. Overall, there were no significant differences between both restricted groups, regarding neither LW nor milk yield reductions (LW reduction 13 % and milk yield reduction of 87 % for both restricted groups). In what concerns control groups, there were no significant differences between breeds, thought there were different increments at the end of the trial for both breeds regarding LW (6 and 4 %, for Majorera and Palmera, respectively) and milk yield (28 and 8 %, respectively for Majorera and Palmera). The lack of statistically significant differences between Palmera and Majorera LW and milk yields in restricted groups may be due to the fact that the controlled trial does not replicate harsh field conditions, in which Majorera would excel, and the stress induced by those differences.

    Notwithstanding the solar radiation is recognized as a detrimental factor to the thermal balance and responses of animals on the range in tropical conditions, studies on the amount of thermal radiation absorbed by goats therein associated with data on their production and heat exchange are still lacking. Metabolic heat production and the heat exchange of goats in the sun and in the shade were measured simultaneously, aiming to observe its thermal equilibrium. The results showed that black goats absorb twice as much as the white goats under intense solar radiation (higher than 800 W m-2). This observation leads to a higher surface temperature of black goats, but it must not be seen as a disadvantage, because they increase their sensible heat flow in the coat-air interface, especially the convection heat flow at high wind speeds. In the shade, no difference between the coat colours was observed and both presented a lower absorption of heat and a lower sensible heat flow gain. When solar radiation levels increases from 300 to 1000 W m-2, we observed an increase of the heat losses through latent flow in both respiratory and cutaneous surface. Cutaneous evaporation was responsible for almost 90 % of the latent heat losses, independently of the coat colour. Goats decrease the metabolic heat production under solar radiation levels up to 800 W m-2, and increase in levels higher than this, because there is an increase of the respiratory rate and of the respiratory flow, but the fractions of consumed oxygen and produced carbon dioxide are maintained stable. The respiratory rate of black goats was higher than the white ones, under 300 W m-2 (55 and 45 resp min-1) and 1000 W m-2 (120 and 95 resp min-1, respectively). It was concluded that shade or any protection against solar radiation levels above 800 Wm-2 is critical to guarantee goat's thermal equilibrium. Strategies concerning the grazing period in accordance with the time of the day alone are not appropriate, because the

Farm management practices have been identified as risk factors associated with Brucella sero-positivity in many studies. Our finding in this study should be considered in order to strengthen the system of biosecurity control in farm animals as one health approach. The objectives of the study were to describe the distribution of potential risk factors by types of goat farms and to document the prevalence of human Brucella sero-positivity among goat keepers and livestock officers in Nakhon Si Thammarat, Thailand. A cross-sectional study was conducted from September to December 2012. The study population included three types of goat farms: standard, community enterprise and private goat farms that were located in Nakhon Si Thammmarat Province in southern Thailand. Information on whether the farm had any Brucella sero-positivity goats since 2011 was retrieved from the local livestock office records. Information on farming management was also traced back to 2011. Field researchers collected information from goat keepers of the selected farms using a structured questionnaire. Goat keepers on all farms pre-identified (January to June 2012) as having had at least one positive goat were considered to have been exposed. Goat keepers on a random sample of farms having all goats with negative results were considered to be unexposed. Venous blood samples were collected from goat keepers exposed and unexposed and from livestock officers and the samples were tested by IgG ELISA. Statistical analysis was done under the complex survey design in R software. Fourteen standard farms, 66 community enterprise farms and 68 private farms participated in the study; 82.4% (122/148) used public pasture and 53.4% (79/148) shared breeder goats with other farms.

    2016-06-01

    Full Text Available ABSTRACT This study estimates the technical efficiency of goat rearing in the province of Isparta in Turkey using Data Envelopment Analysis (DEA. The data used were collected from 92 goat farmers using the stratified sampling method by means of a questionnaire. The technical efficiency of the goat farming varied widely between 0.13 and 1.00. The mean efficiency of 92 goat farms was calculated to be 0.44 and 0.66 for constant and variable returns to scale assumptions, respectively. The greatest slacks were in feedstuff concentrates and labour used. The most significant factors affecting efficiency of goat production were farmer experience, cooperative membership, milk yield per goat, and family and hired labour. Technical efficiency should be improved by providing farmers with well-organised education, an extension program, and research and development programs on goat rearing.

    Full Text Available Among calcium sensitive caseins, β-casein is the most abundant in goat milk, representing up to 50% of total casein content. The goat β-casein locus has been widely investigated and at least ten alleles have been identified in different goat breeds. The aim of this work was to investigate the polymorphisms of β-casein gene in Girgentana dairy goat breed in order to assess the genotype distribution and evaluate how frequencies have changed during the last 10 years, as genotype is known to influence technological and nutritional milk properties. Sequencing analysis and alignment of the obtained sequences of β-casein exon 7, showed the presence of C, C1, and A strong alleles, and 0' null allele, with frequencies of 0.597, 0.326, 0.023, and 0.054, respectively. Seven genotypic classes were found in Girgentana goat breed and the most frequent genotype was CC1 (0.423 followed by CC (0.326, C1C1 (0.110, and C0' (0.096. No AA nor 0'0' homozygous individuals were found. The presence of strong alleles at CSN2 gene in Girgentana goat breed could be useful for the production of milk with high protein content and good cheese-making properties. Moreover, food business operators should consider the possibility of reviving interest in Girgentana goat milk using weak and null genotypes at CSN2 locus to make peculiar food products, such as drinking milk.

  12. The Effect of C. burnetii Infection on the Cytokine Response of PBMCs from Pregnant Goats

    In humans, infection with Coxiella burnetii, the causative agent of Q fever, leads to acute or chronic infection, both associated with specific clinical symptoms. In contrast, no symptoms are observed in goats during C. burnetii infection, although infection of the placenta eventually leads to premature delivery, stillbirth and abortion. It is unknown whether these differences in clinical outcome are due to the early immune responses of the goats. Therefore, peripheral blood mononuclear cells (PBMCs) were isolated from pregnant goats. In total, 17 goats were included in the study. Six goats remained naive, while eleven goats were infected with C. burnetii. Toll-like receptor (TLR) and cytokine mRNA expression were measured after in vitro stimulation with heat-killed C. burnetii at different time points (prior infection, day 7, 35 and 56 after infection). In naive goats an increased expression of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-10 and interferon (IFN)-γ mRNA upon C. burnetii stimulation was detected. In addition, TLR2 expression was strongly up-regulated. In goats infected with C. burnetii, PBMCs re-stimulated in vitro with C. burnetii, expressed significantly more TNF-α mRNA and IFN-γ mRNA compared to naive goats. In contrast, IL-10 mRNA production capacity was down-regulated during C. burnetii infection. Interestingly, at day 7 after inoculation a decreased IFN-γ protein level was observed in stimulated leukocytes in whole blood from infected goats, whereas at other time-points increased production of IFN-γ protein was seen. Our study shows that goats initiate a robust pro-inflammatory immune response against C. burnetii in vitro. Furthermore, PBMCs from C. burnetii infected goats show augmented pro-inflammatory cytokine responses compared to PBMCs from non-infected goats. However, despite this pro-inflammatory response, goats are not capable of clearing the C. burnetii infection. PMID:25279829

    Full Text Available The aim of our study was to perform repeated determination of specific antibody levels in mothers and their kids in order to assess indirectly the possibility of vertical transmission of toxoplasmosis in goats. Twenty-eight goats with their kids were included in the study. The following variables were assessed: number of born kids in relation to antibody titres of goats; levels of specific antibodies in the blood of goats and kids; and concentrations of immunoglobulins (Ig, total protein (TP and total globulins (G in order to define the end of colostral immunity and the start of active production of antibodies in kids under 69 days of age. Specific antibodies against Toxoplasma gondii in goats were detected by IFAT in titres ranging from 0 to 1 280. Out of a total of 28 animals, 5 goats were negative (17.9% and 23 goats were seropositive (82.1%. The goats delivered 42 kids. A total ratio of number of kids to number of mothers was 1.5. Partial evaluation of results in goats without positive titre against T. gondii before parturition and goats with positive titre showed that negative goats tended to have more kids (p p < 0.01 of monitored non-specific immunity indicators. During this period, we observed increased titres of specific antibodies against toxoplasmosis in 20 kids (5 kids 41 days old, 5 kids 55 days old, and 10 kids 69 days old and thus we could assume the possibility of vertical transmission of toxoplasmosis.

    2013-10-01

    Full Text Available The paper purpose was to identify the main trends in the Romanian sheep and goat meat market based on the analysis of the specific indicators regarding sheep and goat livestock and production at country level and by region, using the data provided by National Institute of Statistic for the period 1990-2009. About 198,729 farmers are raising sheep and goats and the average farm size is about 16 heads. The sheep and goat livestock declined by 34 % in the analyzed period accounting for 10,058 thousand heads in 2009. Sheep/goat ratio changed from 14/1 in 1990 to 9.96/1 in 2009, in the advantage of goats. Sheep and goats are mainly grown in Central, North-Eastern and South-Western Romania. Mutton and goat meat production accounted for 1,443 thousand tons in 2009, being by 40 % lower than in 1990  because of  livestock  decline.  About 23 % mutton and sheep meat is produced in the South-Eastern Romania, 18 % in the Central part and 14 % in North-East. The share of mutton and goat meat declined from 8.38 % in 1990 to 7.21 % in 2009 in total meat production in the country. As a conclusion,  mutton  and goat meat market registered a decline during the last decades, in favour of pork and poultry meat.

    An adult goat was examined because of behavioral changes and circling. Results of neurologic examination, CSF analysis, hematologic evaluation, and computed tomography of the brain were suggestive of an intra-axial mass. The goat was euthanatized because of worsening neurologic condition and poor prognosis. Necropsy revealed a large mass in the right cerebral hemisphere and caudal brain herniation through the foramen magnum. The mass was diagnosed as a glioma, with oligodendrocyte differentiation. Results of immunohistochemical evaluation were compatible with a malignant, poorly differentiated tumor

    Full Text Available Apesar dos caprinos serem considerados animais rústicos, do ponto de vista bioclimático, a associação entre elevadas temperaturas, umidade e radiação solar pode acarretar alterações fisiológicas, hematológicas, hormonais, reprodutivas e produtivas. Portanto, informações que possam esclarecer o impacto do estresse térmico sobre a eficiência desses aspectos em caprinos, analisando o ambiente em que estão inseridos, e como se comportam frente às adversidades impostas pelo clima, darão uma grande contribuição para a caprinocultura e o fortalecimento de sua cadeia produtiva. Assim, para aumentar a produtividade nas regiões tropicais, deve ser ressaltada a criação de raças que apresentem maior potencial genético de adaptabilidade para uma condição climática adversa, sendo capazes de sobreviver, reproduzir e produzir em situações de estresse térmico.Even though goats are considered rustic animals, regarding the bioclimatic aspect, the association of high temperature, humidity and solar radiation may cause physiological, hematological, hormonal, reproductive and productive changes. Therefore, information explaining the impact of heat stress on the efficiency of these aspects on goats by analyzing the surrounding environment and how these animals behave themselves before the adversities imposed by the climate, will give a great contribution to goat breeding and the strengthening of this productive chain. Thus, to increase the productivity in tropical regions, the breed of animals presenting a major genetic potential of adaptability to adverse climatic conditions must be emphasized breeds that may be able to survive, reproduce and produce efficiently in a situation of heat stress.

  1. Organic livestock production in Uganda: potentials, challenges and prospects.

    Nalubwama, Sylvia Muwanga; Mugisha, Anthony; Vaarst, Mette

    2011-04-01

    Development in organic farming has been stimulated by farmers and consumers becoming interested in healthy food products and sustainable environment. Organic agriculture is a holistic production management system which is based on the principles of health, ecology, care, and fairness. Organic development in Uganda has focused more on the crop sector than livestock sector and has primarily involved the private sector, like organic products export companies and non-governmental organizations. Agriculture in Uganda and many African countries is predominantly traditional, less mechanized, and is usually associated with minimum use of chemical fertilizers, pesticides, and drugs. This low external input agriculture also referred to as "organic by default" can create basis for organic farming where agroecological methods are introduced and present an alternative in terms of intensification to the current low-input/low-output systems. Traditional farming should not be confused with organic farming because in some cases, the existing traditional practices have consequences like overstocking and less attention to soil improvement as well as to animal health and welfare, which is contrary to organic principles of ecology, fairness, health, and care. Challenges of implementing sustainable organic practices in the Ugandan livestock sector threaten its future development, such as vectors and vector-borne diseases, organic feed insufficiency, limited education, research, and support to organic livestock production. The prospects of organic livestock development in Uganda can be enhanced with more scientific research in organic livestock production under local conditions and strengthening institutional support.

Kuntze ex Merr. in the diet of lactating dairy goats arranged in a 5 × 5 Latin square. The diets were composed of 40% of concentrate and 60% of roughage, and the dietary treatments were defined by the level of Flemingia hay inclusion (0%, 8%, 16%, 24%, and 32% in the diet dry matter replacing Cynodon dactyloncv. Tifton 85 hay. The diets were isonitrogenous, with 14% crude protein. Feed intake, nutrient digestibility, feeding behavior, and ruminal pH and ammonia nitrogen were evaluated. There was no difference in dry matter intake with the inclusion of Flemingia hay in the diet. The digestibility of dry matter, organic matter, crude protein, neutral detergent fiber, and total carbohydrates decreased with the inclusion of Flemingia in the diet. The diet did not change rumen ammonia nitrogen concentration or ruminal pH. There were no differences in the feeding behavior or feed and rumination efficiencies. Flemingia macrophylla can be used up to the level of 32% in the dry matter in diets for lactating goats.

    1989-01-01

    The metabolic fate of [phenyl- 14 C]cinmethylin (1), a novel cineole herbicide, in a lactating goat was examined. The test animal was administered four consecutive daily doses equivalent to approximately 100 ppm cinmethylin in the daily diet. The animal was sacrificed 6 h after the last dosing. A rapid and extensive metabolism of cinmethylin was observed. The major route of elimination was via urine: 40% of the administered dose and feces (20%). [ 14 C]Carbon dioxide or radioactive material in the respired air and residual radioactivity in the digestive tract were not monitored. A complex degradation pattern in the excreta and liver tissue was observed. In addition to the undegraded cinmethylin, recovered only in the feces, at least 25 metabolites were isolated and identified as both organic-extractable and conjugated products. They were classified as mono-, di-, trihydroxylated, dehydrated, carboxylated, methoxylated, and ether linkage cleavage products. The level of 14 C residues in the milk and tissues was low and combined to account for less than 1% of the administered radioactivity

    Blastocystis is one of the most common parasites inhabiting in small intestines of human and animals. Although its pathogenicity has been remaining controversial, the possibility of zoonotic transmission between human and animals was recognized. The goat was one of the most important economic animals supplying people with cashmere, meat, and dairy products. However, few studies were to investigate Blastocystis infection in goats. A total of 789 faecal specimens of goats (including 362 of dairy, 193 of meat and 234 of cashmere goats) were collected from multiple regions of Shaanxi province in northwestern China to investigate the colonization frequency and subtypes of Blastocystis, and to assess the zoonotic potential of these goats. The respective colonization frequencies of Blastocystis in dairy, meat and cashmere goats were 54.1% (196/362), 40.4% (78/193) and 78.6% (184/234). The prevalence of Blastocystis in pre-weaned (0-2-month) goats was significantly lower than that in goats of other age groups, and the highest colonization was observed in goats of 7-11-month age group. Sequence analysis of Blastocystis positive samples indicated the presence of seven subtypes in these goats, including six known subtypes (STs1, 3, 4, 5, 10, 14) and one possible novel subtype (isolate Sd26), with the subtype 10 as the predominant one. Additionally, zoonotic subtypes were found in dairy (ST1, ST3 and ST5) and cashmere (ST4 and ST5) goats, but not detected in meat goats. These results showed that Blastocystis is highly prevalent, widely distributed and genetically diverse in goats in Shaanxi province, northwestern China, and zoonotic potential of dairy and cashmere goats to transmit Blastocystis.

    2017-01-01

    The Sultanate of Oman has a complex mosaic of livestock species and production systems, but the genetic diversity, demographic history or origins of these Omani animals has not been expensively studied. Goats might constitute one of the most abundant and important domestic livestock species since the Neolithic transition. Here, we examined the genetic diversity, origin, population structure and demographic history of Omani goats. Specifically, we analyzed a 525-bp fragment of the first hypervariable region of the mitochondrial DNA (mtDNA) control region from 69 Omani individuals and compared this fragment with 17 mtDNA sequences from Somalia and Yemen as well as 18 wild goat species and 1,198 previously published goat sequences from neighboring countries. The studied goat breeds show substantial diversity. The haplotype and nucleotide diversities of Omani goats were found equal to 0.983 ± 0.006 and 0.0284 ± 0.014, respectively. The phylogenetic analyses allowed us to classify Omani goats into three mtDNA haplogroups (A, B and G): haplogroup A was found to be predominant and widely distributed and accounted for 80% of all samples, and haplogroups B and G exhibited low frequencies. Phylogenetic comparisons with wild goats revealed that five of the native Omani goat populations originate from Capra aegagrus. Furthermore, most comparisons of pairwise population FST values within and between these five Omani goat breeds as well as between Omani goats and nine populations from nearby countries were not significant. These results suggest strong gene flow among goat populations caused by the extensive transport of goats and the frequent movements of human populations in ancient Arabia. The findings improve our understanding of the migration routes of modern goats from their region of domestication into southeastern Arabia and thereby shed light on human migratory and commercial networks during historical times.

    2012-01-01

    Full Text Available The effects of inactive dry yeast (Saccharomyces cerevisiae from sugar cane were studied in 18 primiparus Saanen dairy goats (51.07±1.43 on dry matter intake and digestibility, milk production and quality. Animals were distributed in a completely randomized design during 90 days (from day 60 of milking. Diets were composed of soybean meal; soybean meal + dry yeast; or dry yeast, as protein sources, and ground corn, mineral supplement and corn silage (40%. Animals fed the dry yeast diet showed lower intake of dry matter (DM, organic matter (OM, crude protein, ether extract and neutral detergent fiber. Diets did not influence milk yield; however the milk production efficiency (kg of milk produced/kg of crude protein ingested was better in goats fed the dry yeast diet. Acidity, somatic cell counts and milk urea nitrogen values were not affected by treatments. Animals fed the soybean + dry yeast diet had higher fat and total solids than those fed the dry yeast diet. The digestibility of DM, OM and total carbohydrate was lower for soybean only and soybean + dry yeast diets. Total digestible nutrients were higher for dry yeast and soy bean diets than soybean + dry yeast diet. Dry yeast from sugar cane is a good alternative protein source for feeding lactating dairy goats and can be recommended because it maintains the production performance.

  13. Effect of organic fertilizers on maize production in Eastern Georgia

    Jolokhava, Tamar; Kenchiashvili, Naira; Tarkhnishvili, Maia; Ghambashidze, Giorgi

    2016-04-01

    Maize remains to be the most important cereal crop in Georgia. Total area of arable land under cereal crops production equals to 184 thousands hectares (FAO statistical yearbook, 2014), from which maize takes the biggest share. Leading position of maize among other cereal crops is caused by its dual purpose as food and feed product. In Spite of a relatively high production of maize to other cereals there is still a high demand on it, especially as feed for animal husbandry. The same tendency is seen in organic production, where producers of livestock and poultry products require organically grown maize, the average yield of which is much less than those produced conventionally. Therefore, it is important to increase productivity of maize in organic farms. Current study aimed to improve maize yield using locally produced organic fertilizers and to compare them to the effect of mineral fertilizers. The study was carried out in Eastern Georgia under dry subtropical climate conditions on local hybrid of maize. This is the first attempt to use hybrid maize (developed with organic plant breeding method) in organic field trials in Georgia. The results shown, that grain yield from two different types of organic fertilizers reached 70% of the yields achieved with industrial mineral fertilizers. As on farm level differences between organic and conventional maize production are much severe, the results from the field trials seems to be promising for future improvement of organic cereal crop production.

    R. Gasigwa Sabimana

    2018-03-01

    Full Text Available Prospects for the development of goat breeding in the Democratic Republic of Congo seem favorable. Knowledge of the characteristics of local goat farming by breeders is a very important factor to control and promote goat production. The objective of this study was to improve the productivity of Mbanza-Ngungu’s local goat by increasing the knowledge of its reproductive performance. To achieve this objective, data were collected by direct observation of the goats. These data were used to simulate reproductive and population dynamics parameters over a five-year period. The study showed the relevance of the model to simulate the reproduction traits of Mbanza-Ngungu’s goats and that it is useless to keep them beyond five years.

  16. New ways of organizing product introductions.

    Berglund, Martina; Harlin, Ulrika; Gustavsson, Maria; Säfsten, Kristina

    2012-01-01

    The aim of this paper is to describe and reflect on an interactive research approach used to address the challenges on how to improve product introductions, the part of the product realization process associated with the transfer of a product from product development to serial production. In the interactive research approach, research results as well as improvement of practice are given equal importance. The collaboration between researchers and practitioners therefore addresses both the focus and the process of the change. The approach includes four main iterative steps: 1) mapping/diagnosis, 2) feedback of results, 3) participation in development activities, and 4) follow-up/evaluation. The paper reports findings from interactive research in one company within office product industry and one company group, consisting of three company units within the engine industry. Preliminary findings indicate that the participating companies afterwards work in a more structured way with product introductions and that the employees have gained deeper knowledge about product introductions as well as experienced the advantages of working across functional boundaries. Furthermore, the interactive research approach is suitable to run projects from an ergonomics perspective as it focuses on developing both practice and theory, it is human-centered, and it emphasizes broad participation from practitioners.

    Full Text Available The recent statistical data and market studies have shown that the organic products market is on a continuouslyupward trend in Europe and globally. For Romania, organic agriculture represents a market niche that is stillinsufficiently exploited, with a definite and real development potential of the agricultural sector. The role of theconsumer is decisive for the evolution trends and future prospects of any market. A questionnaire based quantitativeresearch was done to find out the Romanian consumers’ behaviour related to organic products, which allowed theestablishment of the weight of organic products consumers within the population interviewed, the extent to whichthe characteristics of organic products, brands and categories known and consumed are acknowledged. The studyalso pursued the evaluation of motivational factors which determine the purchase, market appraisal between thealleged favourable attitude towards organic products and product consumption, the evaluation of the way in whichthe Romanian organic products’ quality is perceived in relation with their price.The study shows an increase in consumer interest for “healthy” products, so that the change according to theirbehaviour shall generate an increase in the organic products market in Romania.

    Goat milk is only limited to the processing of goat milk powder and liquid milk, the products are mainly about milk powder and a few of them are made as milk tablet. Therefore, the study of probiotic goat milk will have great significance in the full use of goats and the development of the goat milk industry in China. The effect of fermentation temperature (35°C, 37°C, 39°C), strain ratio (1:1:1, 2:1:1, 3:1:1) and inoculum size (4%, 5%, 6%) on viable counts of L. acidophilus and B. bifidum, total bacteria and sensory value during fermentation process of L. acidophilus and B. bifidum goat yogurt (AB-goat yogurt) was investigated. The optimum fermentation conditions for AB-goat yogurt were: fermentation temperature 38°C, the strain ratio 2:1:1, inoculum size 6%. Under the optimum conditions, the viable counts of B. bifidum, L. acidophilus, total bacteria and sensory value reached (4.30 ±0.11)×107  cfu/mL, (1.39 ±0.09)×108  cfu/mL, (1.82±0.06)×109  cfu/mL and 7.90 ±0.14, respectively. The fermentation temperature, the strain ratio and inoculum size had a significant effect on the fermentation of AB-goat yogurt and these results are beneficial for developing AB-goat yogurt.

  7. Goat for Azazel

    Sylwester Jędrzejewski

    2007-03-01

    Full Text Available The rite included in Leviticus 16 belongs to penitential rites of purification. It may be a reminiscence of antic religious medical-magic rites, practiced in multiple regions of ancient world. The rites contained the idea of substitution, “magic elimination.” Sending the goat represents rejection of anything that should not and can not exist among the people of Israel. The desert as an “infertile” place, the theological idea of separating the good from the evil as well as the ancient idea of substitution point at the theology of penance expressed in the rite of separation. The text of Leviticus 16 applies the term sa‘ir for the goat. The same term is also applied in priestly text to describe demons relating to the misshapen form of Israel religion. There is an undoubted connection with the idea of Convenant that constitutes the basic background and point of reference for the rite of Leviticus 16.

  10. Comparing the profitability of organic and conventional broiler production

    F Cobanoglu

    2014-03-01

    Full Text Available Recently, organic broiler chicken production has received more attention worldwide. This study has carried out an economic analysis to compare the profitability of organic versus conventional growing systems per unit of broiler meat production. To achieve this goal, 400 slow-growing broiler chickens (Hubbard Red-JA were reared in an organic production system, and the same number of fast-growing birds (Ross-308 in a conventional system. The profitability was deduced with an economic analysis that compared total costs and net income. Results showed that organic broiler meat can cost from 70% to 86% more with respect to variable and fixed costs when compared with conventional production. The main reasons for the higher cost of organic broiler meat were feed, labor, certification, and outdoor area maintenance. The proportion of fixed costs in total costs was 1.54% in the conventional system and 7.48% in the organic system. The net income per kg of chicken meat in the organic system was € 0.75, which is 180% higher than chicken meat grown in a conventional system (€ 0.27; however, the price of organic broiler meat sold in the present study was twice as high as that obtained for conventional broilers. In conclusion, organic broiler meat production was more profitable than conventional rearing.

  12. The social organization of agricultural biogas production and use

    Bluemling, Bettina; Mol, Arthur P.J.; Tu, Qin

    2013-01-01

    While for wind, solar energy or hydropower, energy supply happens directly from the source to the wind wheels, hydropower turbines or solar panels, in the case of biogas, energy production cannot directly take from the energy source, organic matter, but depends on the institutional structures and farmers′ practices involved for making energy available. With the production of bioenergy in rural areas, practices within agriculture are transformed, requiring new ways of organizing production processes. Research has left the question largely unanswered of how agricultural biogas production and use are – and can best be – organized within rural society. Which kinds of social organization exist, how are these embedded in existing agricultural institutions and practices, and how do these systems function? Under which conditions may the different kinds of social organization of biogas production and use work sustainably? This introduction article to the Special Issue “The social organization of agricultural biogas production and use” presents a framework for analysing the different kinds of social organization of biogas production and use presented hereafter. Analysis parameters are the supply network, distribution network, distribution of benefits, social boundaries of the system (accessibility) and scale. Using these parameters, the Special Issue articles are outlined. - Highlights: • Through agricultural institutions and farmers′ practices, biogas is made available. • Scale, supply and delivery network distinguish biogas infrastructural systems. • Access and benefit distribution are key for a biogas system′s sustainability

  13. PRODUCTION AND MARKETABILITY OF CONVENTIONAL, SUSTAINABLE AND ORGANIC PRODUCED TOMATOES

    2007-07-01

    Full Text Available Conventional agricultural production is denoted by high levels of chemisation, strait specialised production, high yields and low costs per production unit, however this production causes risky interventions, which could affect negatively on environment and human health Research results indicate possibilities for growing vegetables in alternative systems, less risky for environment with satisfying economic success. The aim of this research was to determine economic success of organic, sustainable and conventional production of tomato in the Mediterranean area of Republic Croatia. Bianual research was conducted during 2002/2003. During vegetation we examined parameters of growth, marketable yields and costs for materials, work and machinery which are used in economic analysis. Economical analysis of tomatoes production indicate worst results in organic production system. Loses in tomatoes organic production were consequences of two main factors: lower marketed yield and equal product price for all three production types. Lower yields in organic production were expected, therefore bad financial results were caused by mainly low market prices, which do not validate quality and food safety. Therefore financial success is preconditioned by higher market validation, which can be obtained through market analysis and product development. Consumer awareness about organic agriculture is still very weak and this point requires further attention. The link between organic agriculture and the environment/nature protection is missing too. The purchase of organic food is influenced by the level of information and knowledge of consumers with reference to these products. Doubts about the truthfulness and significance of some data were raised by main places where organic food is purchased, since an excessive greatest limitations are high prices and a low level of information to consumers. Current standard of life of most Croatian consumers does not permit them to

  14. Comparison of the Fecal Microbiota in Feral and Domestic Goats

    María G. Domínguez-Bello

    2011-12-01

    Full Text Available Animals have co-evolved with mutualistic microbial communities, known as the microbiota, which are essential for organ development and function. We hypothesize that modern animal husbandry practices exert an impact on the intestinal microbiota. In this study, we compared the structure of the fecal microbiota between feral and domestic goats using the G2 PhyloChip and assessed the presence of five tetracycline resistance genes [tet(M, tet(S, tet(O, tet(Q and tet(W] by PCR. Feces were collected from 10 goats: 5 domestic from a farm in the main island of Puerto Rico and 5 feral from the remote dry island of Mona. There were 42 bacterial phyla from 153 families detected in the goats’ feces. A total of 84 PhyloChip-OTUs were different in the fecal microbiota of feral and domestic goat. Both feral and domestic goats carried antibiotic resistance genes tet(O and tet(W, but domestic goats additionally carried tet(Q. Diet, host genetics and antibiotic exposure are likely determinant factors in shaping the intestinal microbiota and may explain the differences observed between feral and domestic goats fecal microbiota.

  15. Ultrasonography of the omasum in 30 Saanen goats

    Jacquat Désirée

    2011-02-01

    Full Text Available Abstract Background Primary diseases of the omasum are uncommon in goats, although the omasum may be involved in various gastrointestinal disorders. Examination of the caprine omasum via ultrasonography requires a good understanding of the normal appearance of the organ. However, in contrast to cattle, there is a lack of reference information on this topic in goats. Thus, the goal of the present study was to describe the results of ultrasonography of the omasum in 30 healthy Saanen goats. Results Ultrasonography was carried out in standing, non-sedated goats using a 5.0 MHz linear transducer. The location and size of the omasum, thickness of the omasal wall and visualisation of the abomasal laminae, contents and contractions were assessed. The omasum was visible from the 9th intercostal space (ICS in all the goats, and from the 8th and 10th ICSs in 29 and 24 goats, respectively. The omasum was seen medial to the liver, but only the omasal wall closest to the transducer was visible. The dorsal omasal limit formed a dorsally convex curve running from cranioventral to caudodorsal and was furthest from the dorsal midline in the 6th ICS. The ventral omasal limit formed a ventrally convex curve. The size of the omasum was largest (10.2 ± 3.1 cm in the 9th ICS and decreased cranially and caudally from this position. Active omasal motility was recorded in 20 goats with 0.3 to 2.0 contractions per minute. Conclusions The findings of this study provide reference ranges for the interpretation of the location and size of the omasum in goats with suspected omasal abnormalities. Ultrasonography is an ideal diagnostic tool for evaluation of the omasum, which is not accessible to conventional examination techniques, such as inspection, palpation, percussion and auscultation.

  16. Evolution of chemical-physical parameters and rheological characteristics of Sarda and Maltese goat dry hams

    Rina Mazzette

    2012-10-01

    Full Text Available In Sardinia, goat farming is a very important resource. Sarda and Maltese breed are reared mainly for milk production and for suckling kids meat, while meat from adult goats is undervalued. The use of adult goat meat to obtain ripened ham will contribute to safeguard the Sardinian goat supply chain. The aim of the present study was to characterize Sarda and Maltese goat dry ham in order to evaluate the quality of autochthonous goat breed meat. Chemical-physical characteristics were determined dur-ing the production stages, while the rheological and colour parameters and the composition of the goat ham were determined at the end of ripening. The pH evolution during processing were similar to other cured meat products, e.g. sheep hams, even though the values were high, especially in the products from Sarda breed. The aw value regularly decreased during processing. Colour parameters (L*, a*, b* in the hams from Maltese goat breed were significantly (P<0.05 higher than in those from Sarda. The Sarda goat ham showed a significantly lower percentage of moisture (42% vs 52%, an higher protein content (44.35% vs 34.19%, while no differences were pointed out in the total fat content. Among the ham rheological properties, hardness parameters showed higher levels (13850.22±7589.92 vs 11073.99±6481.31, respectively in Sarda and Maltese hams in comparison to similar products from pork and sheep, while adhesiveness value was lower. The results show that the quality parameters of goat ripened hams are affected mainly by the charac-teristics of the goat meat, in relation on the breed and the breeding system, and, less, by the traditional technology.

    Full Text Available In order to study the efficiency resulting from optimization of energy consumptionin organic farming, the amount of consumption and production inputs and their costs, obtained profit, cultivated area and … was estimated in conjuction with the three crop of wheat, canola and tomato in Iran over a five year period 2006-2011. Using the objective function and constraints, the DEA method was used to analyze the data. All the processes of models estimation was performed using DEAP software. To calculate the energy amount in external inputs consumption in conventional and organic farming were used coefficients to convert the amount of energy input consumption, too. Finally, the energy consumptions were compared in the two cultures. According to these results, the use of organic fertilizers and biological inputs (in consequence of more energy consumption in organic specific inputs leads to lower productivity growth in organic products. These results were significant in the 5 and 1 percent levels, respectively. Due to the type of used inputs in the inorganic products, in fuel inputs, nitrogen fertilizer, phosphate fertilizer, insecticide and fungicide, inorganic products had more consumption and hence the amount of energy inputs for organic products was higher. In the case of biofertilizer and biocontrol were also used in organic production, input energy in this part was more than input energy of inorganic products. Organic farms with lower energy consumption of imports and inputs, led to production of more energy in output. Thus the efficiency besides saving of energy consumption occurred in organic products.

  20. Sustainability of organic food production: challenges and innovations.

    Niggli, Urs

    2015-02-01

    The greatest challenge for agriculture is to reduce the trade-offs between productivity and long-term sustainability. Therefore, it is interesting to analyse organic agriculture which is a given set of farm practices that emphasise ecological sustainability. Organic agriculture can be characterised as being less driven by off-farm inputs and being better embedded in ecosystem functions. The literature on public goods and non-commodity outputs of organic farms is overwhelming. Most publications address the positive effects of organic farming on soil fertility, biodiversity maintenance and protection of the natural resources of soil, water and air. As a consequence of focusing on public goods, organic agriculture is less productive. Meta-analyses show that organic agriculture yields range between 0·75 and 0·8 of conventional agriculture. Best practice examples from disadvantaged sites and climate conditions show equal or, in the case of subsistence farming in Sub-Saharan Africa, higher productivity of organic agriculture. Hence, organic agriculture is likely to be a good model for productive and sustainable food production. Underfunding in R&D addressing specific bottlenecks of organic agriculture are the main cause for both crop and livestock yield gaps. Therefore, the potential for improving the performance of organic agriculture through agricultural research is huge. Although organic farming is a niche in most countries, it is at the verge of becoming mainstream in leading European countries. Consumer demand has grown over the past two decades and does not seem to be a limiting factor for the future development of organic agriculture.

  1. Morphometric and Phylogenic Analysis of Six Population Indonesian Local Goats

    2011-12-01

    Full Text Available The research objectives were to characterize morphometric and genetic distance between populations of Indonesian local goats. The morphological discriminant and canonical analysis were carried out to estimate the phylogenic relationship and determine the discriminant variable between Benggala goats (n= 96, Marica (n= 60, Jawarandu (n= 94, (Kacang (n= 217, Muara (n= 30 and Samosir (n= 42. Discriminant analysis used to clasify body weight and body measurements. In the analysis of variance showed that body weight and body measurement (body length, height at withers, thorax width, thorax height, hert girth, skull width and height, tail length and width, ear length and width of Muara goats was higher (P<0.05 compared to the other groups, and the lowest was in Marica goats. The smallest genetic distance was between Marica and Samosir (11.207 and the highest were between Muara and Benggala (255.110. The highest similarity between individual within population was found in Kacang (99.28% and the lowest in Samosir (82.50%. The canonical analysis showed high correlation on canon circumference, body weight, skull width, skull height, and tail width variables so these six variables can be used as distinguishing variables among population. The result from Mahalonobis distance for phenogram tree and canonical analysis showed that six populations of Indonesian local goats were divided into six breed of goats: the first was Muara, the second was Jawarandu, the third was Kacang, the fourth was Benggala, the fifth was Samosir and the sixth was Marica goats. The diversity of body size and body weight of goats was observed quite large, so the chances of increasing productivity could be made through selection and mating programs.

  4. The Organic Products in the Green Marketing Laboratory

    Victor Danciu

    2008-01-01

    Full Text Available A healthy way of life requires green products which protect the environment and the quality of life. Organic products have relevant green characteristics and particular benefits for the consumers, the producers and the environment. The benefits support the rapidly growing world market of organic food in both developed and developing countries. Green issues and products have a growing importance in Romania. Even if the Romanians have not become fans of the green products yet, a growing number of consumers prefer organic food. More important, Romanian organic food has success on the export markets. Supporting and promoting organic products on both domestic and international markets requires significant efforts, including those in the green marketing area. The requirements of the green marketing imply new thinking and acting towards new responsibilities and solutions. The task of the marketing is to bring on the market the green problems under the form of new products, the change of the existing products through ecological improvement and abandoning the ecologically obsolete products.

    1991-09-20

    The US Department of Energy's Office of Health and Environmental Research (OHER) has supported work in our laboratory since 1977. The general theme of this program has been the identification of potentially toxic organic compounds associated with various combustion effluents, following the fates of these compounds in the environment, and improving the analytical methodology for making these measurements. The projects currently investigation include: an improved sampler for semi-volatile compounds in the atmosphere; the wet and dry deposition of dioxins and furans from the atmosphere; the photodegradation and mobile sources of dioxins and furans; and the bioaccumulation of PAH by tree bark. These projects are all responsive to OHER's interest in the pathways and mechanisms by which energy-related agents move through and are modified by the atmosphere''. The projects on gas chromatographic and liquid chromatographic tandem mass spectrometry are both responsive to OHER's interest in new and more sensitive technologies for chemical measurements''. 35 refs., 9 figs.

  8. Bone turnover markers in sheep and goat: A review of the scientific literature

    JOSÉ A. CAMASSA

    Full Text Available ABSTRACT Bone turnover markers (BTMs are product of bone cell activity and are generally divided in bone formation and bone resorption markers. The purpose of this review was to structure the available information on the use of BTMs in studies on small ruminants, especially for monitoring their variations related to diet, exercise, gestation and metabolic lactation state, circadian and seasonal variations, and also during skeletal growth. Pre-clinical and translational studies using BTMs with sheep and goats as animal models in orthopaedic research studies to help in the evaluation of the fracture healing process and osteoporosis research are also described in this review. The available information from the reviewed studies was systematically organized in order to highlight the most promising BTMs in small ruminant research, as well as provide a wide view of the use of sheep and goat as animal models in orthopaedic research, type of markers and commercial assay kits with cross-reactivity in sheep and goat, method of sample and storage of serum and urine for bone turnover markers determination and the usefulness and limitations of bone turnover markers in the different studies, therefore an effective tool for researchers that seek answers to different questions while using BTMs in small ruminants.

  9. ORGANIZATION OF INFORMATION INTERACTION OF AIRPORT PRODUCTION PROCESSES

    2017-01-01

    Full Text Available The organization of service production attributed to airports activity is analyzed. The importance and the actuality of information interaction problem solution between productive processes as a problem of organization of modern produc- tion are shown.Possibilities and features of information interaction system construction in form of multi-level hierarchical struc- ture have been shown. The airport is considered as an enterprise aimed at service production where it is necessary to analyze much in- formation in a limited time-frame. The production schedule often changes under the influence of many factors. This leads to the increase of the role of computerization and informatization of production processes what predetermines automation of production, creation of information environment and organization of information interaction needed for realization of production processes. The integrated organization form is proposed because it is oriented to the integration of different processes into a universal production system and it allows to conduct the coordination of local goals of particular processes in the context of the global purpose aimed at the improvement of the effectiveness of the airport activity. The main conditions needed for organization of information interaction between production processes and techno- logical operations are considered, and the list of the following problems is determined. The attention is paid to the necessity of compatibility of structure and organization of interaction system in the conditions of the airline and the necessity of be- ing its reflection in the information space of the airline. The usefulness of the intergrated organization form of information interaction based on information exchange between processes and service customers according to the network structure is explained. Multi-level character of this structure confirms its advantage over other items, however it also has a series of features presented

  17. A comparative analysis of acceptance by Japanese females and price of goat milk from different sources.

    Ozawa, Takeyuki; Takada, Ruriko; Nishitani, Jiro; Fujita, Masaru; Blair, Hugh T

    2010-04-01

    A sensory survey was carried out using 4 different types of whole goat milk among middle-class females to investigate consumer acceptability of goat milk and whether there is an opportunity to expand the sale of goat milk products in Japan. Four different types of whole milk powder (domestic concentrate-fed, domestic pasture-fed, USA commercially canned, and New Zealand commercially canned) were used. Fresh cow milk was served as a control. Thirty-one housewives evaluated the 5 liquid milk samples for smell, taste and overall characteristics on a scale of 1 (low) to 3 (high). Chi-square analyses were carried out to detect significant differences between the milk types in each category. The goat milk from the USA was the most preferred goat milk with respect to smell and overall evaluation. Domestic pasture-fed milk received the lowest grade in the evaluation for its 'grassy and goaty' smell. This result shows us that pasture intake affects the taste and smell of powdered milk which gives the lowest evaluation by the participants. If Japanese goat milk producers want to be successful in the domestic goat milk market and compete against goat milk products from other countries, they should improve production methods and flavor of their products.

  19. Study of organic waste for production of hydrogen in reactor

    Guzmán Chinea, Jesús Manuel; Guzmán Marrero, Elizabeth; Pérez Ponce, Alejandro

    2015-01-01

    Biological processes have long been used for the treatment of organic waste makes, especially our study is based on the anaerobic process in reactors, using residual organic industry. Without excluding other non-industrial we have studied. Fundamental objectives treating organic waste is to reduce the pollutant load to the environment, another aim is to recover the waste recovering the energy contained in it. In this context, the biological hydrogen production from organic waste is an interesting alternative because it has low operating costs and raw material is being used as a residue in any way should be treated before final disposal. Hydrogen can be produced sustainable by anaerobic bacteria that grow in the dark with rich carbohydrate substrates giving as final products H 2 , CO 2 and volatile fatty acids. The whey byproduct from cheese production, has great potential to be used for the generation of hydrogen as it has a high carbohydrate content and a high organic load. The main advantages of using anaerobic processes in biological treatment of organic waste, are the low operating costs, low power consumption, the ability to degrade high organic loads, resistance biomass to stay long in the absence of substrate, without lose their metabolic activity, and low nutritional requirements and increase the performance of 0.9 mol H2 / mol lactose.

  20. Fate and metabolism of radiolabelled insecticide Coumaphos in egyptian lactating goats

    Osman, A.Z.; Zayed, S.M.A.D.; Hazzaa, N.I.

    1986-01-01

    Our study was initiated to determine the residues of 14 C-coumaphos and its metabolites which might appear in milk, meat and other different organs of lactating goats subjected to coumaphos treatment. 14 C-coumaohos (Asunto) was synthesized and applied dermally on two lactating goats. Two equal dermal applications, with 2 weeks interval, were applied on each goat. One goat was sacrificed 24 hours after the second application, and the second animal after a withdrawal period of two weeks. The results indicate that coumaphos has a slow absorption rate when dermally applied to lactating goats. After the withdrawal period, liver, kidney, skin and subcutaneous fat were found to contain considerable amounts of coumaphos residues in comparison with other different organs and milk. Thin layer chromatography showed the presence of coumaphos, its oxygen analogue, and two unknown metabolites.3 fig.,2 tab

    Rumen microorganisms are responsible for digestion and utilization of dietary feeds by host ruminants. Unconventional feed resources could be used as alternatives in tropical areas where feed resources are insufficient in terms of quality and quantity. The objective of the present experiment was to evaluate the effect of diets based on palm oil (PO), decanter cake (DC) or palm kernel cake (PKC) on rumen total bacteria, selected cellulolytic bacteria, and methanogenic archaea. Four diets: control diet (CD), decanter cake diet (DCD), palm kernel cake diet (PKCD) and CD plus 5% PO diet (CPOD) were fed to rumen cannulated goats and rumen samples were collected at the start of the experimental diets (day 0) and on days 4, 6, 8, 12, 18, 24 and 30 post dietary treatments. Feeding DCD and PKCD resulted in significantly higher (Pgoats fed PKCD and CPOD and the trend showed a severe reduction on days 4 and 6 post experimental diets. In conclusion, results indicated that feeding DCD and PKC increased the populations of cellulolytic bacteria and decreased the density of methanogenic archaea in the rumen of goats.

    Full Text Available To make better the life, it is required safety foods for health. The health foods can be satisfied by organic farming. Organic farming is farming system based on biomass recycling or eliminating the use of materials as a synthetic agrochemical inputs. To determine whether the result of rice called as an organic product needs to be certified by the Organic Certification Board (OCB. According to the Indonesian National Standard (INS 6729: 2013, organic farming systems (OFS are not only limited to not use material agrochemical synthetic, but must meet the requirements of OFS in rice production ranging from cultivating, handling, storage, processing, transportation, labeling, marketing, production facilities and other materials that are allowed start on farm to off farm should be separated from conventional agriculture. The farm is just a negate the use of synthetic agrochemicals without regard to the cultivation process and the system of post-harvest organic results are said to be premium food which is not as organic food, because organic food is food produced from OFS by applying processing practices to preserve the ecosystem of sustainable, control of weeds, pests, diseases, selection and crop rotation, water management, land preparation and planting and the use of biological materials. Thus the system of organic agriculture is a holistic management system to improve and develop the agro-ecosystem health, including biodiversity, biological cycles and soil biological activity. The first step that must be done is the conversion of land for food crops from anorganic to organic farming for 2 years did not get the requisite amount of agrochemical applied to the soil for annual crop and 3 years for perennial crops. If agriculture in paddy soil can control the conventional farms into OFS, then the resulting rice is as an organic product.

  6. Factors of welfare reduction in dairy sheep and goats

    Antonio Pazzona

    2010-01-01

    Full Text Available Scientific research on factors causing the reduction of well-being in sheep and goats is rather recent, as are studies of strategies to minimize the adverse effects of environmental challenges and improper management practices on flock welfare. Sheep and goats, considered very rustic animals, are reared prevalently under extensive production systems and are widespread mainly in marginal areas. For these reasons, only few studies on the welfare of these species have been carried out in the past. More recently, the scenario has changed, due to a gradual diffusion of intensive and semi-intensive production systems, especially in dairy sheep and goat breeds, to the growing concern of consumers about the life conditions of farmed animals, and to the issuing of a number of rules and laws on the safety of animal products and well-being of farmed livestock. As a consequence, several research groups have turned their attention to the welfare of sheep and goats. Nevertheless, information on this topic is still scarce. This paper reviews major critical points regarding the endangerment of welfare in farmed sheep and goats. Climatic extremes and seasonal fluctuations in herbage amount and quality are discussed as important causes of the reduction of well-being in extensive production systems, which can impair production efficiency of grazing animals and dramatically affect the welfare and health status of sheep and goats. Space allowance and structures of sheep and goat houses are described as the main potential sources of discomfort for housed flocks, together with inadequate control of micro-environment, and inappropriate milking procedures and human-animal interactions. Recent studies on the impact of high ambient temperature, different ventilation regimes, high stocking densities, reduced airspace and poor litter management on behaviour, immune and endocrine response, and on performance of sheep and goats are discussed. The effects of inadequate milking

    HACCP provides an effective, logical and structured means of assuring food safety. Although first used in food manufacturing operations, HACCP can be – and, increasingly is – applied to food production and handling operations at all stages in the food chain. This includes the primary production sector. The purpose of this paper is to illustrate how the principles of HACCP can be applied to organic production with special reference to the primary sector.

  8. MODELLING CONSUMERS' DEMAND FOR ORGANIC FOOD PRODUCTS: THE SWEDISH EXPERIENCE

    Manuchehr Irandoust

    2016-07-01

    Full Text Available This paper attempts to examine a few factors characterizing consumer preferences and behavior towards organic food products in the south of Sweden using a proportional odds model which captures the natural ordering of dependent variables and any inherent nonlinearities. The findings show that consumer's choice for organic food depends on perceived benefits of organic food (environment, health, and quality and consumer's perception and attitudes towards labelling system, message framing, and local origin. In addition, high willingness to pay and income level will increase the probability to buy organic food, while the cultural differences and socio-demographic characteristics have no effect on consumer behaviour and attitudes towards organic food products. Policy implications are offered.

  9. Bio-hydrogen production from renewable organic wastes

    Shihwu Sung

    2004-04-30

    Methane fermentation has been in practice over a century for the stabilization of high strength organic waste/wastewater. Although methanogenesis is a well established process and methane--the end-product of methanogenesis is a useful energy source; it is a low value end product with relatively less energy content (about 56 kJ energy/g CH{sub 4}). Besides, methane and its combustion by-product are powerful greenhouse gases, and responsible for global climate change. So there is a pressing need to explore alternative environmental technologies that not only stabilize the waste/wastewater but also generate benign high value end products. From this perspective, anaerobic bioconversion of organic wastes to hydrogen gas is an attractive option that achieves both goals. From energy security stand point, generation of hydrogen energy from renewable organic waste/wastewater could substitute non-renewable fossil fuels, over two-third of which is imported from politically unstable countries. Thus, biological hydrogen production from renewable organic waste through dark fermentation represents a critically important area of bioenergy production. This study evaluated both process engineering and microbial physiology of biohydrogen production.

  12. Norwegian farmers ceasing certified organic production: characteristics and reasons.

    Flaten, Ola; Lien, Gudbrand; Koesling, Matthias; Løes, Anne-Kristin

    2010-12-01

    This article examines the characteristics of and reasons for Norwegian farmers' ceasing or planning to cease certified organic production. We gathered cross-sectional survey data in late 2007 from organic farmers deregistering between January 2004 and September 2007 (n=220), and similar data from a random sample of farmers with certified organic management in 2006 (n=407). Of the respondents deregistering by November 2007, 17% had quit farming altogether, 61% now farmed conventionally, and 21% were still farming by organic principles, but without certification. Nearly one in four organic farmers in 2007 indicated that they planned to cease certification within the next 5-10 years. From the two survey samples, we categorised farmers who expect to be deregistered in 5-10 years into three groups: conventional practices (n=139), continuing to farm using organic principles (uncertified organic deregistrants, n=105), and stopped farming (n=33). Of the numerous differences among these groups, two were most striking: the superior sales of uncertified organic deregistrants through consumer-direct marketing and the lowest shares of organic land among conventional deregistrants. We summarised a large number of reasons for deregistering into five factors through factor analysis: economics, regulations, knowledge-exchange, production, and market access. Items relating to economics and regulations were the primary reasons offered for opting out. The regression analysis showed that the various factors were associated with several explanatory variables. Regulations, for example, figured more highly among livestock farmers than crop farmers. The economic factor strongly reflected just a few years of organic management. Policy recommendations for reducing the number of dropouts are to focus on economics, environmental attitudes, and the regulatory issues surrounding certified organic production.

  13. SELECTING ANGORA GOATS TO CONSUME MORE JUNIPER

    Christopher John Lupton

    2009-02-01

    Full Text Available This research project was initiated in 2003 to develop a more effective tool for biological management of invading juniper species on rangelands through herbivory by Angora goats.  After we had established that juniper consumption in free-ranging goats has a genetic component (heritability = 13%, male and female goats were bred selectively for above- (high and below-average (low juniper consumption that was estimated by fecal near-infrared reflectance spectroscopy. Divergent lines are being produced to facilitate the identification of physiological mechanisms that permit some goats to consume considerably more juniper than others as a regular component of their diet.  Because diet is known to affect growth and fiber production, another objective of the project is to establish the effects of the selection protocol on body weights, fleece weights, and fiber characteristics.  Mature females (age > 1.5 yr and kids were maintained on rangeland and shorn twice a year.  Extreme high- and low-consuming yearling males (10 of each per year were evaluated annually in a central performance test.  The selection protocol resulted in average EBV for percentage juniper consumption of 3.9 and -0.4 (P 0.1 in body weight, mohair production and properties between high and low consumers.  However, the adult data for the extreme males indicated that high consuming males have lower body weights than low consumers (53.8 vs. 57.9 kg, P = 0.01. Differences in body weight and several mohair production and quality traits have also been detected in the mature females but at this early stage of the selection program, no substantial differences have been observed and certainly none that would have an economic impact for producers.  Ultimately, we expect to demonstrate that the high-consuming line controls juniper more effectively than either the low-consuming line or unselected Angora goats.  Subsequently, we plan to release high juniper

  14. CONVERSION PRODUCT STRUCTURE AS TOOL TO INCREASE YIELD PROCESSING ORGANIZATIONS

    A. I. Khorev

    2014-01-01

    Full Text Available The authors' analysis of the performance of organizations, processing raw materials of agricultural origin, in particular, dealing with meat processing, identified the need to develop tools to increase their profitability. Unlike common approaches to assessing the profitability of the processing organizations, taking into account only the interests of the organization's leadership and buyers of products, the authors proposed and implemented a concept based on the interests of participants in the triune balance business activities: owners of capital, management organizations and consumers. As one of the tools for improving the yield of processing organizations are invited to transform their product mix of economic evaluations of profitability of each product line positions. Russian researchers income from product sales are traditionally measured by indicators such as net income, income from sales, profit margins and profitability level - in terms of return on sales. The disadvantage of using these indicators, according to the authors, is their lack of objectivity in the evaluation of the effectiveness of investment business owners. In this work was used unconventional and non-proliferation in the Russian practice, the rate of economic value added (EVA, a built - in system of profitability assortment positions. As indicators, the production of a particular product line units proposed and used two quantitative indicators - EVA level per unit of production and profitability of production (for EVA, as well as a quality parameter - the level of demand. Developed by the evaluation program transformation product structure represented as a matrix management capabilities, allowing to achieve a balance of interests of the triune main participants in business activity.

  16. Altered lipid and salt taste responsivity in ghrelin and GOAT null mice.

    Huan Cai

    Full Text Available Taste perception plays an important role in regulating food preference, eating behavior and energy homeostasis. Taste perception is modulated by a variety of factors, including gastric hormones such as ghrelin. Ghrelin can regulate growth hormone release, food intake, adiposity, and energy metabolism. Octanoylation of ghrelin by ghrelin O-acyltransferase (GOAT is a specific post-translational modification which is essential for many biological activities of ghrelin. Ghrelin and GOAT are both widely expressed in many organs including the gustatory system. In the current study, overall metabolic profiles were assessed in wild-type (WT, ghrelin knockout (ghrelin(-/-, and GOAT knockout (GOAT(-/- mice. Ghrelin(-/- mice exhibited decreased food intake, increased plasma triglycerides and increased ketone bodies compared to WT mice while demonstrating WT-like body weight, fat composition and glucose control. In contrast GOAT(-/- mice exhibited reduced body weight, adiposity, resting glucose and insulin levels compared to WT mice. Brief access taste behavioral tests were performed to determine taste responsivity in WT, ghrelin(-/- and GOAT(-/- mice. Ghrelin and GOAT null mice possessed reduced lipid taste responsivity. Furthermore, we found that salty taste responsivity was attenuated in ghrelin(-/- mice, yet potentiated in GOAT(-/- mice compared to WT mice. Expression of the potential lipid taste regulators Cd36 and Gpr120 were reduced in the taste buds of ghrelin and GOAT null mice, while the salt-sensitive ENaC subunit was increased in GOAT(-/- mice compared with WT mice. The altered expression of Cd36, Gpr120 and ENaC may be responsible for the altered lipid and salt taste perception in ghrelin(-/- and GOAT(-/- mice. The data presented in the current study potentially implicates ghrelin signaling activity in the modulation of both lipid and salt taste modalities.

    Goat and sheep milks have long been used to produce a range of dairy products due to their nutritional value and health benefits. Information about the microstructure and rheology of goat and sheep yoghurts, however, is scarce. In this study, the microstructure, texture and rheological properties of cow, goat and sheep yoghurts were investigated and compared. The results show that a longer fermentation and gelation time was required for goat yoghurt with a lower storage modulus compared to cow and sheep yoghurts. Cooling resulted in an increase in the storage modulus at different magnitudes for cow, goat and sheep yoghurts. Goat yoghurt had a smaller particle size and a softer gel, which is linked with a more porous microstructure. The results obtained here demonstrate the effect of different milk types on the properties of yoghurts and provide a better understanding into the link between the microstructure and physical properties of the product.

  19. Biodiesel production by various oleaginous microorganisms from organic wastes.

    Cho, Hyun Uk; Park, Jong Moon

    2018-05-01

    Biodiesel is a biodegradable and renewable fuel. A large amount of research has considered microbial oil production using oleaginous microorganisms, but the commercialization of microbial lipids produced in this way remains uncertain due to the high cost of feedstock or low lipid yield. Microbial lipids can be typically produced by microalgae, yeasts, and bacteria; the lipid yields of these microorganisms can be improved by using sufficient concentrations of organic carbon sources. Therefore, combining low-cost organic compounds contained in organic wastes with cultivation of oleaginous microorganisms can be a promising approach to obtain commercial viability. However, to achieve effective bioconversion of low-cost substrates to microbial lipids, the characteristics of each microorganism and each substrate should be considered simultaneously. This article discusses recent approaches to developing cost-effective microbial lipid production processes that use various oleaginous microorganisms and organic wastes.

  20. Factors affecting somatic cell count in dairy goats: a review

    Jimenez-Granda, R.; Sanchez-Rodriguez, M.; Arce, C.; Rodriguez-Estevez, V.

    2014-06-01

    Somatic cell count (SCC) in monitoring udder health has been described in numerous studies as a useful method for the diagnosis of intramammary infection (IMI), and it is considered in standards of quality and hygiene of cows milk in many countries. However, several authors have questioned the validity of SCC as a reliable IMI diagnosis tool in dairy goats. This review attempts to reflect the importance of different infectious and non-infectious factors that can modify SCC values in goat milk, and must, therefore, be taken into account when using the SCC as a tool in the improvement of udder health and the quality of milk in this species. In dairy goats, some investigations have shown that mammary bacterial infections are a major cause of increased SCC and loss of production. In goats however, the relationship between bacterial infections and SCC values is not as simple as in dairy cattle, since non-infectious factors also have a big impact on SCC. Intrinsic factors are those that depend directly on the animal: time and number of lactation (higher SCC late in lactation and in aged goats), prolificity (higher SCC in multiple births), milking time (higher SCC in evening compared to morning milking) and number of milkings per day, among others. Extrinsic factors include: milking routine (lower SCC in machine than in manual milking), seasonality and food. In addition, milk secretion in goats is mostly apocrine and therefore characterized by the presence of epithelial debris or cytoplasmic particles, which makes the use of DNA specific counters mandatory. All this information is of interest in order to correctly interpret the SCC in goat milk and to establish differential SCC standards. (Author)

  4. Organic Substances from Unconventional Oil and Gas Production in Shale

    Orem, W. H.; Varonka, M.; Crosby, L.; Schell, T.; Bates, A.; Engle, M.

    2014-12-01

    Unconventional oil and gas (UOG) production has emerged as an important element in the US and world energy mix. Technological innovations in the oil and gas industry, especially horizontal drilling and hydraulic fracturing, allow for the enhanced release of oil and natural gas from shale compared to conventional oil and gas production. This has made commercial exploitation possible on a large scale. Although UOG is enormously successful, there is surprisingly little known about the effects of this technology on the targeted shale formation and on environmental impacts of oil and gas production at the surface. We examined water samples from both conventional and UOG shale wells to determine the composition, source and fate of organic substances present. Extraction of hydrocarbon from shale plays involves the creation and expansion of fractures through the hydraulic fracturing process. This process involves the injection of large volumes of a water-sand mix treated with organic and inorganic chemicals to assist the process and prop open the fractures created. Formation water from a well in the New Albany Shale that was not hydraulically fractured (no injected chemicals) had total organic carbon (TOC) levels that averaged 8 mg/L, and organic substances that included: long-chain fatty acids, alkanes, polycyclic aromatic hydrocarbons, heterocyclic compounds, alkyl benzenes, and alkyl phenols. In contrast, water from UOG production in the Marcellus Shale had TOC levels as high as 5,500 mg/L, and contained a range of organic chemicals including, solvents, biocides, scale inhibitors, and other organic chemicals at thousands of μg/L for individual compounds. These chemicals and TOC decreased rapidly over the first 20 days of water recovery as injected fluids were recovered, but residual organic compounds (some naturally-occurring) remained up to 250 days after the start of water recovery (TOC 10-30 mg/L). Results show how hydraulic fracturing changes the organic

    2009-01-01

    A model of consumer decision-making and behaviour with regard to organic food is developed and applied on survey data from eight European countries. It is found that the reasons given and the reasoning behind choosing organic products are quite similar across countries and are independent...... on the processing level of the product. However, whereas behavioural intentions are predictive of behaviour in the North, this is to a much lesser extend the case in the South of Europe. Policy implications and possible reasons for the difference between North and South are discussed....

  6. Extinction of Harrington's mountain goat

    Keratinous horn sheaths of the extinct Harrington's mountain goat, Oreamnos harringtoni, were recovered at or near the surface of dry caves of the Grand Canyon, Arizona. Twenty-three separate specimens from two caves were dated nondestructively by the tandem accelerator mass spectrometer (TAMS). Both the TAMS and the conventional dates indicate that Harrington's mountain goat occupied the Grand Canyon for at least 19,000 years prior to becoming extinct by 11,160 +/- 125 radiocarbon years before present. The youngest average radiocarbon dates on Shasta ground sloths, Nothrotheriops shastensis, from the region are not significantly younger than those on extinct mountain goats. Rather than sequential extinction with Harrington's mountain goat disappearing from the Grand Canyon before the ground sloths, as one might predict in view of evidence of climatic warming at the time, the losses were concurrent. Both extinctions coincide with the regional arrival of Clovis hunters

  7. Commercialization channels of organic products in Brazil: analysis at the first level of the production chain

    Andréa Rossi Scalco

    2017-10-01

    Full Text Available Abstract Specialized literature on organic production highlights the presence and concentration of retail, especially supermarkets, in the organic enhancement chain. This presents enormous obstacles for the entrance of small farmers in the production of organic products due to administrative barriers, in addition to pressure for lower prices by the supermarket retail network. This paper investigates the commercialization channels of organic production in Brazil. The survey was undertaken in 2013; questionnaires were sent to 900 out of approximately 11.200 farmers producing organic products; 216 answers were received. Analysis showed that approximately 90% of farmers provided for the internal market and 60% of the products were fresh fruits and vegetables. The distribution of organic products in Brazil is highly fragmented at the local, regional and national levels. The presence of supermarkets and intermediaries in the commercialization of fruits and vegetables is relevant, regardless of the size of the farm. There is a great dispersion of channels in the case of small farmers, although supermarkets rank second. However, direct commercialization (farmers markets is the main form of commercialization of the produce. Commercialization triggered by social programs has guaranteed a considerable part of the income on small production units or small farms. It seems that high involvement of retail networks and agents in the agribusiness segment causes low development rates in small agricultural units and in local development due to the latter’s low profit margins.

    Full Text Available Dietary energy level is a limiting factor of milk production mainly in early lactation goats. Energy intake may be increased by incorporation of fat in ration. Currently, rumen protected fat is mainly adopted in goats nutrition, since the several studies have clearly confirmed that supplies of protected fat markedly improved the fat percentage of goat milk (Schmidely and Sauvant, 2001; Chilliard et al., 2003.

  9. Cassava dreg as replacement of corn in goat kid diets.

    2018-02-01

    The effects of corn replacement by cassava dreg in diets of crossbred goat kids were evaluated. We tested the impacts of 0, 33, 66 and 100% replacement on intake, digestibility, feeding behaviour, performance and carcass characteristics. Thirty-six goat kids, aged between 4 and 5 months and with initial body weights of 17.61 ± 1.98 kg, were used in a completely randomised design. Analysis of regression revealed a negative linear effect on neutral detergent fibre (NDF) intake and a positive linear effect on non-fibrous carbohydrates (NFC) and hydrocyanic acids (HCN) intake. Cassava dreg use had a positive linear effect on organic matter digestibility and non-fibrous carbohydrates. Based on our results, cassava dreg use did not negatively impact animal performance, feeding behaviour and carcass characteristics, suggesting that it may replace corn up to 100% in the diets of confined goat kids.

  10. Q Fever in Pregnant Goats: Pathogenesis and Excretion of Coxiella burnetii

    Roest, Hendrik-Jan; van Gelderen, Betty; Dinkla, Annemieke; Frangoulidis, Dimitrios; van Zijderveld, Fred; Rebel, Johanna; van Keulen, Lucien

    Coxiella burnetii is an intracellular bacterial pathogen that causes Q fever. Infected pregnant goats are a major source of human infection. However, the tissue dissemination and excretion pathway of the pathogen in goats are still poorly understood. To better understand Q fever pathogenesis, we inoculated groups of pregnant goats via the intranasal route with a recent Dutch outbreak C. burnetii isolate. Tissue dissemination and excretion of the pathogen were followed for up to 95 days after parturition. Goats were successfully infected via the intranasal route. PCR and immunohistochemistry showed strong tropism of C. burnetii towards the placenta at two to four weeks after inoculation. Bacterial replication seemed to occur predominantly in the trophoblasts of the placenta and not in other organs of goats and kids. The amount of C. burnetii DNA in the organs of goats and kids increased towards parturition. After parturition it decreased to undetectable levels: after 81 days post-parturition in goats and after 28 days post-parturition in kids. Infected goats gave birth to live or dead kids. High numbers of C. burnetii were excreted during abortion, but also during parturition of liveborn kids. C. burnetii was not detected in faeces or vaginal mucus before parturition. Our results are the first to demonstrate that pregnant goats can be infected via the intranasal route. C. burnetii has a strong tropism for the trophoblasts of the placenta and is not excreted before parturition; pathogen excretion occurs during birth of dead as well as healthy animals. Besides abortions, normal deliveries in C. burnetii-infected goats should be considered as a major zoonotic risk for Q fever in humans. PMID:23152826

  11. Consumer perception, health information, and instrumental parameters of cupuassu (Theobroma grandiflorum) goat milk yogurts.

    Although the demand for goat milk products has been growing, they have lower consumer acceptability than products derived from cow milk. However, the addition of cupuassu pulp can be used to improve the formulation of these products. For this reason, the aim of this study was to investigate the influence of new goat milk yogurt manufactured with cupuassu pulp on physicochemical properties, consumers' perceptions, and overall consumer acceptance. In addition, the effect of antioxidant health information on consumer acceptance and purchase intention of cupuassu goat milk yogurts was evaluated. The results demonstrated a positive expectation regarding linking and familiarity to goat milk products and products with cupuassu pulp. The pH, total phenolic content, lightness, redness, yellowness, and apparent viscosity were potentially affected by the addition of cupuassu, with the highest concentration of cupuassu (10%) exhibiting the greatest changes in parameters. Based on principal component analysis, partial least squares regression, and just-about-right and penalty analysis, the addition of cupuassu pulp improved some sensory attributes of goat milk yogurt, such as cupuassu aroma, cupuassu flavor, yellow color, consistency, and viscosity, which positively influenced product acceptance. In addition, antioxidant health information increased the acceptance and purchase intention of cupuassu goat milk yogurts. Taking into account the parameters investigated in this study, the best scoring formulation was goat milk yogurt with 10% cupuassu pulp. Our results suggest that cupuassu pulp can be considered a potential ingredient to improve the sensory and texture properties of goat milk yogurt. Furthermore, the antioxidant health information could be a sensory strategy to increase the acceptance of cupuassu goat milk yogurts. Copyright © 2017 American Dairy Science Association.

    1980-01-01

    The influence of primary and secondary degradation products from TBP - dodecane on zirconium extraction is studied. The presence of radiolytical degradation at organic phase, in systems of initial concentration of HNO 3 1 and 4M, and absorbed γ radiation doses from 0,5 to 4,5 Wh/l, lead to an increase of zirconium extraction, being the HDBP the main product of degradation responsable by this effect. The influence of secondary degradation products is significative in systems of HNO 3 1M initial concentration. The formation of precipitator in extractions of Zr in HNO 3 1M with irradiated TBP-dodecane was observed. (M.C.K.) [pt

    The objective of the study was to compare factors influencing water scarcity for goats in areas where there are seasonal and perennial rivers under resource-limited communal farming environments. Data were collected using a structured questionnaire (n = 285) administered randomly to smallholder goat farmers from areas with seasonal and perennial rivers. Ceremonies was ranked as the major reason for keeping goats. Water scarcity was ranked the major constraint to goat production in areas with seasonal rivers when compared to areas with perennial rivers (P goat drinking in areas with seasonal and perennial river systems during cool dry and rainy seasons. Rivers were ranked as an important water source for goat drinking where there are seasonal and perennial river systems during the cool dry season. Households located close (≤ 3 km) to the nearest water source reported drinking water for goats a scarce resource. These results show that river systems, season and distance to the nearest water source from a household were factors perceived by farmers to influence water scarcity for goats in resource-limited communal farming environments. Farmers should explore water-saving strategies such as recycling wastewater from kitchens and bathrooms as an alternative water source. The government may assist farmers through sinking boreholes to supply water for both humans and livestock.

  2. Acidic organic compounds in beverage, food, and feed production.

    Quitmann, Hendrich; Fan, Rong; Czermak, Peter

    2014-01-01

    Organic acids and their derivatives are frequently used in beverage, food, and feed production. Acidic additives may act as buffers to regulate acidity, antioxidants, preservatives, flavor enhancers, and sequestrants. Beneficial effects on animal health and growth performance have been observed when using acidic substances as feed additives. Organic acids could be classified in groups according to their chemical structure. Each group of organic acids has its own specific properties and is used for different applications. Organic acids with low molecular weight (e.g. acetic acid, lactic acid, and citric acid), which are part of the primary metabolism, are often produced by fermentation. Others are produced more economically by chemical synthesis based on petrochemical raw materials on an industrial scale (e.g. formic acid, propionic and benzoic acid). Biotechnology-based production is of interest due to legislation, consumer demand for natural ingredients, and increasing environmental awareness. In the United States, for example, biocatalytically produced esters for food applications can be labeled as "natural," whereas identical conventional acid catalyst-based molecules cannot. Natural esters command a price several times that of non-natural esters. Biotechnological routes need to be optimized regarding raw materials and yield, microorganisms, and recovery methods. New bioprocesses are being developed for organic acids, which are at this time commercially produced by chemical synthesis. Moreover, new organic acids that could be produced with biotechnological methods are under investigation for food applications.

  3. Organizing product innovation: hierarchy, market or triple-helix networks?

    Fitjar, Rune Dahl; Gjelsvik, Martin; Rodríguez-Pose, Andrés

    This paper assesses the extent to which the organization of the innovation effort in firms, as well as the geographical scale at which this effort is pursued, affects the capacity to benefit from product innovations. Three alternative modes of organization are studied: hierarchy, market and triple-helix-type networks. Furthermore, we consider triple-helix networks at three geographical scales: local, national and international. These relationships are tested on a random sample of 763 firms located in five urban regions of Norway which reported having introduced new products or services during the preceding 3 years. The analysis shows that firms exploiting internal hierarchy or triple-helix networks with a wide range of partners managed to derive a significantly higher share of their income from new products, compared to those that mainly relied on outsourcing within the market. In addition, the analysis shows that the geographical scale of cooperation in networks, as well as the type of partner used, matters for the capacity of firms to benefit from product innovation. In particular, firms that collaborate in international triple-helix-type networks involving suppliers, customers and R&D institutions extract a higher share of their income from product innovations, regardless of whether they organize the processes internally or through the network.

  4. Production of bioethanol from organic whey using Kluyveromyces marxianus

    Christensen, A.D.; Kádár, Zsófia; Oleskowicz-Popiel, Piotr

    2011-01-01

    Ethanol production by K. marxianus in whey from organic cheese production was examined in batch and continuous mode. The results showed that no pasteurization or freezing of the whey was necessary and that K. marxianus was able to compete with the lactic acid bacteria added during cheese production...... ethanol yield (~0.50 g ethanol/g lactose) at both 30°C and 40°C using low pH (4.5) or no pH control. Continuous fermentation of nonsterilized whey was performed using Ca-alginate-immobilized K. marxianus. High ethanol productivity (2.5-4.5 g/l/h) was achieved at dilution rate of 0.2/h......, and it was concluded that K. marxianus is very suitable for industrial ethanol production from whey. © 2010 Society for Industrial Microbiology....

  5. Depletion of long-acting ampicillin in goat milk following intramuscular administration.

    Ferrini, Anna Maria; Trenta, Simona; Mannoni, Veruscka; Rosati, Remo; Coni, Ettore

    2010-12-08

    Although goat milk production represents today a very small percentage of the world milk market, this percentage has been growing continuously during the past 20 years. Goat milk is the basic milk supply in many developing countries and provides tasteful derivative products in developed countries. Goats, as well as all milk-producing animals, can be affected by mastitis, but goats being considered a minor species, few drugs are specifically registered for these animals; most, at least for mastitis treatment, are usually tested and registered for use in cows. This situation leads often to the adoption for goat milk of withdrawal periods defined for cows even if these extrapolations prove almost never valid for goats. In the present study, the elimination of the β-lactam antibacterial agent ampicillin in goat milk was investigated. Ampicillin was chosen because it is one of the most common antibiotics used by goat farmers against mastitis due to the fact that it is well tolerated and has short elimination times in cows. Goats were treated with long-acting ampicillin at 15 mg (kg of body weight)(-1) by double intramuscular injection at 72 h interval. Milk was collected in a 12 h milking scheme. The method used to determine the levels of ampicillin in goat milk was based on a liquid-liquid extraction of this drug from the matrix, successive derivatization with formaldehyde, and final separation by HPLC with fluorescence detection. The results point out a slow depletion of ampicillin and, consequently, a withdrawal period (13 milkings) longer than that extrapolated and authorized for cows and sheep.

  6. Gamma ray irradiated goat milk: comparative sensorial analysis with pasteurized goat milk

    Gurgel, Maria Sylvia de C.C. do Amaral; Domarco, Rachel E.; Spoto, Marta H.F.

    2002-01-01

    Goat milk consumption has increased in the last years, due to its better digestibility and for constituting a good alternative to cow milk for intolerant people. Brazil has over 10 millions goats, mainly in the Northeast area. Considering that it is very important to increase the shelf-life for this product, this work was done to test the gamma-radiation as a preservation method, evaluating acceptability by sensorial analysis compared with pasteurized milk. The goat milk was bought in the Animal Production Department/ESALQ/USP, Piracicaba, and irradiated with 3,5 kGy in the Food Irradiation Laboratory/CENA/USP, using a cobalt-60 irradiator, type Gammabeam-650, from Nordion, Canada. After irradiation, the samples were maintained under refrigeration at 5 deg C and submitted to sensorial analysis at 1 st , 7 th and 15 th days by 30 untrained tasters. The results indicated, by Tukey test, a significant preference for the pasteurized milk in comparison to the irradiated one, because a hard caprine flavor was developed by the irradiation. (author)

  7. Botanical alternatives to antibiotics for use in organic poultry production.

    Diaz-Sanchez, Sandra; D'Souza, Doris; Biswas, Debrabrata; Hanning, Irene

    2015-06-01

    The development of antibiotic resistant pathogens has resulted from the use of sub-therapeutic concentrations of antibiotics delivered in poultry feed. Furthermore, there are a number of consumer concerns regarding the use of antibiotics in food animals including residue contamination of poultry products and antibiotic resistant bacterial pathogens. These issues have resulted in recommendations to reduce the use of antibiotics as growth promoters in livestock in the United States. Unlike conventional production, organic systems are not permitted to use antibiotics. Thus, both conventional and organic poultry production need alternative methods to improve growth and performance of poultry. Herbs, spices, and various other plant extracts are being evaluated as alternatives to antibiotics and some do have growth promoting effects, antimicrobial properties, and other health-related benefits. This review aims to provide an overview of herbs, spices, and plant extracts, currently defined as phytobiotics as potential feed additives. © 2015 Poultry Science Association Inc.

    Cryptosporidiosis, microsporidiosis, and giardiasis contribute significantly to the high burden of zoonotic diarrhea worldwide. Goats constitute an important species in animal agriculture by providing cashmere wool, meat, and dairy products for human consumption. However, zoonotic pathogens with the potential to cause morbidity and to degrade production have been reported frequently in goats recently. The present study examined 629 fecal specimens from goats, including 315 cashmere goats, 170 dairy goats and 144 meat goats, in multiple cities of Shaanxi and Henan provinces, northwestern and central China, to investigate the infection rate and species/assemblages/genotypes of Giardia duodenalis, Cryptosporidium spp. and Enterocytozoon bieneusi. Of these samples, 274 (43.6%) were positive for three zoonotic pathogens, including 80 (12.7%), 104 (16.5%) and 179 (28.5%) for G. duodenalis, Cryptosporidium spp. and E. bieneusi, respectively. Infections with G. duodenalis, Cryptosporidium spp. and E. bieneusi existed in meat, dairy and cashmere goats, with the highest infection rate of each pathogen being observed in meat goats. DNA sequencing of the SSU rRNA gene from 104 Cryptosporidium-positive specimens revealed existence of Cryptosporidium xiaoi, and the zoonotic parasites Cryptosporidium parvum and Cryptosporidium ubiquitum. Genotyping of G. duodenalis based on the triosephosphate isomerase (TPI) gene identified parasites from zoonotic assemblage A in four cashmere goats and the animal-adapted assemblage E in a group of 76 goats that included cashmere, dairy and meat animals. Polymorphisms in the ribosomal internal transcribed spacer characterized E. bieneusi genotype CHG1 and a novel genotype named as SX1 in both dairy and cashmere goats, genotypes CHS7 and COSI in meat goats, the genotype CHG2 in dairy goats, and the human-pathogenic genotype BEB6 in dairy and meat goats. This is the first detailed study to compare infection rate of the zoonotic protozoan pathogens

  14. Planning organization and productivity simulation tool for maritime container terminals

    B. Beškovnik

    2010-09-01

    Full Text Available The article describes a proposed planning organization and productivity simulation tool, with a special emphasis on orientations to the optimization of operations in a maritime container terminal. With the application of an adequate model frame for traffic and technical-technologic forecasting, infrastructure and manpower planning and productivity simulation are possible to measure and increase the productivity in the whole subsystem of the maritime container terminal. The emphasis is mainly put on setting up planning organization in order to collect important information and consequently to raise productivity. This is the main task and goal of terminal management that must develop elements and strategies for optimal operational and financial production. An adequate planning structure must use simplified but efficient simulation tools enabling owners and management to take a vast number of adequate financial and operational decisions. Considering all important and very dynamic facts in container and shipping industry, the proposed simulation tool gives a helpful instrument for checking productivity and its time variation and monitoring a competitive position of a certain maritime terminal with the terminals from the same group. Therefore, the management of every maritime container terminal must establish an appropriate internal planning system as a mechanism for strategic decision support relating basically to the assessment of the best development and optimization solutions for the infrastructure and suprastructure of the entire system.

  15. Fertilization management in bean crop under organic production system

    2015-03-01

    Full Text Available Nowadays the food production systems tend to include the sustainable management of soil and water. One of the main obstacles to the organic cultivation of common bean is the fertilization management. This study aimed to evaluate doses of organic fertilizer containing slaughterhouse residues (1.0 t ha-1, 1.5 t ha-1, 2.0 t ha-1 and 2.5 t ha-1. The experimental design was randomized blocks in a 4x2x2 factorial scheme, with 16 treatments and 4 replications. Plant dry weight; foliar diagnose; initial and final plant population; number of pods per plant, grains per plant and grains per pod; 1000-grain weight; and grain yield were evaluated. It was concluded that the methods and time of organic fertilizer application do not affect the production components and yield in common bean. The dose of 2.5 t ha-1 of organic fertilizer provided the highest common bean yield in 2012, but it did not express its maximum production capacity.

  16. Effect of Feeding Oxidized Soybean Oil against Antioxidant role of Pomegranate Seed on Physiology and Metabolism of Periparturient Saanen Goats

    2016-08-01

    Full Text Available Introduction Oxidative stress is metabolic and physiologic status caused by imbalance between free radical production and antioxidant defense of body. In some physiological status such as rapid growth, parturition, disease and high production rate that imbalance would occur. High producing dairy animals are suspected to oxidative stress and require to antioxidant supplementation. Negative energy balance in early lactation force the nutrition specialist to apply oil and high NFC diet to exceed the requirement of high producing dairy animals such as Holstein cows and Saanen goats. In recent years, the attention to the use of herbal or organic antioxidant in animal nutrition has increased. This study was carried out to investigate the effects of feeding oxidized soybean oil (OSO plus pomegranate seed (PS as a natural antioxidant, on metabolism and physiology of Preparturient Saanen Goats. Materials and Methods Eighteen Saanen dairy goats with initial body weight of 47 ± 9 kg were assigned to three dietary treatments in a completely randomized design with repeated measurements for 21 days before anticipated parturition. Experimental treatments including: 1 base diet and 4% fresh soybean oil (FSO, 2 base diet and 4% oxidized soybean oil (DM basis respectively, and 3 base diet plus 4% OSO and 8% Pomegranate seed (OSO-PS. After 2 weeks of feeding trial diets, goats were sampled for blood, rumen liquor, faeces and urine for measuring parameters of blood glucose, BHBA, lipid and nitrogen profile, rumen liquor ammonia nitrogen, urine pH and volume, faeces qualitative and quantitative variables and other responses such as nutrients digestibility. The GLM procedure of SAS software v.9.2 were used for statistical analysis. Initial body weight and metabolic variables were used as covariate in the model. Results and discussion All nutrients digestibility, Ruminal ammonia nitrogen and voluntary feed intake were decreased by OSO (p

  17. Production and efficiency of organic compost generated by millipede activity

    2016-05-01

    Full Text Available ABSTRACT: The putrefactive activity of organisms such as diplopods in the edaphic macrof auna can be leveraged to promote the transformation of agricultural and urban waste into a low-cost substrate for the production of vegetable seedlings. This research aimed to evaluate: (1 the quantity of Gervais millipedes ( Trigoniulus corallinus needed to produce an acceptable quantity of organic compost; (2 the main physical and chemical characteristics of different compost types; and (3 compost efficiency in the production of lettuce seedlings. The first experiment lasted 90 days and was conducted using 6.5L of Gliricidia, 6.5L of Flemingia, 13.5L of grass cuttings, 4.5L of cardboard, 4.5L of coconut husk, and 4.5L of corncob. Treatments consisting of 0, 0.10, 0.30, 0.50, and 0.90L of millipedes were applied. This experiment compared millicompost and vermicompost, using four repetitions. After 23 days, the heights of grown lettuce plants and the weights of the fresh and dry mass of above ground lettuce and of the roots were assessed. A millipede volume of 0.1L proved to be sufficient for the production of an acceptable volume of organic compost. However, the addition of greater volumes leads to increased calcium, magnesium, and phosphorous content. Millicompost has similar physicochemical characteristics those of vermicompost, and both are equally efficient as a substrate for the production of lettuce seedlings.

    2015-06-01

    Full Text Available The volumes of waste generated in the fishing activity are increasing due to the increase in demand for these products. This implies the need for fast processing and cycling of these materials. Thus, the aim of this study was to evaluate the use of waste generated in the fishing activity as a source of organic fertilizers in agricultural production systems familiar ecological basis. The experiment was conducted at the Experimental Station Cascade / Embrapa Temperate Climate was assessed throughout the composting process and the fermentation of fish waste, identifying the main points that enable the use of these fertilizers in farming systems ecological base. The composting process of rice husk revealed be incomplete during the experiment. The compound prepared with fish waste and exhausted bark of acacia presents itself as a good source of nutrients for crops, which may be suitable as organic fertilizer for production of ecologically-based systems. For liquid organic fertilizer, the conditions under which the experiment was conducted, it is concluded that the compound resulting from aerobic or anaerobic fermentation of fish waste, present themselves as a viable source of nutrients for productive systems of ecological base. However, further studies need to be conducted to better understanding and qualification of both processes.

  19. Production of Valuables Organic Acids from Organic Wastes with Hydrothermal Treatment Process

    2009-06-01

    Full Text Available This article reports production of valuables organic acids from the hydrothermal treatment of representative organic wastes and compounds (i. e. domestic sludge, proteinaceous, cellulosic and plastic wastes with or without oxidant (H2O2. Organic acids such as acetic, formic, propionic, succinic and lactic acids were obtained in significant amounts. At 623 K (16.5 MPa, acetic acid of about 26 mg/g-dry waste fish entrails was obtained. This increased to 42 mg/g dry waste fish entrails in the presence of H2O2. Experiments on glucose to represent cellulosic wastes were also carried out, getting acetic acid of about 29 mg/g-glucose. The study was extended to terephthalic acid and glyceraldehyde, reaction intermediates of hydrothermal treatment of PET plastic wastes and glucose, respectively. Studies on temperature dependence of formation of organic acids showed thermal stability of acetic acid, whereas, formic acid decomposed readily under hydrothermal conditions. In general, results demonstrated that the presence of oxidants favored formation of organic acids with acetic acid being the major product.

  20. Evaluation of Organic Proxies for Quantifying Past Primary Productivity

    Raja, M.; Rosell-Melé, A.; Galbraith, E.

    2017-12-01

    Ocean primary productivity is a key element of the marine carbon cycle. However, its quantitative reconstruction in the past relies on the use of biogeochemical models as the available proxy approaches are qualitative at best. Here, we present an approach that evaluates the use of phytoplanktonic biomarkers (i.e. chlorins and alkenones) as quantitative proxies to reconstruct past changes in marine productivity. We compare biomarkers contents in a global suite of core-top sediments to sea-surface chlorophyll-a abundance estimated by satellites over the last 20 years, and the results are compared to total organic carbon (TOC). We also assess satellite data and detect satellite limitations and biases due to the complexity of optical properties and the actual defined algorithms. Our findings show that sedimentary chlorins can be used to track total sea-surface chlorophyll-a abundance as an indicator for past primary productivity. However, degradation processes restrict the application of this proxy to concentrations below a threshold value (1µg/g). Below this threshold, chlorins are a useful tool to identify reducing conditions when used as part of a multiproxy approach to assess redox sedimentary conditions (e.g. using Re, U). This is based on the link between anoxic/disoxic conditions and the flux of organic matter from the sea-surface to the sediments. We also show that TOC is less accurate than chlorins for estimating sea-surface chlorophyll-a due to the contribution of terrigenous organic matter, and the different degradation pathways of all organic compounds that TOC includes. Alkenones concentration also relates to primary productivity, but they are constrained by different processes in different regions. In conclusion, as lons as specific constraints are taken into account, our study evaluates the use of chlorins and alkenones as quantitative proxies of past primary productivity, with more accuracy than by using TOC.

    Hermann, Theron; Reinhardt, James; Yu, Xiaohui; Udani, Russell; Staples, Lauren

    2018-05-01

    This invention relates to improvements in the fermentation process used in the production of organic acids from biological feedstock using bacterial catalysts. The improvements in the fermentation process involve providing a fermentation medium comprising an appropriate form of inorganic carbon, an appropriate amount of aeration and a biocatalyst with an enhanced ability to uptake and assimilate the inorganic carbon into the organic acids. This invention also provides, as a part of an integrated fermentation facility, a novel process for producing a solid source of inorganic carbon by sequestering carbon released from the fermentation in an alkali solution.

    2014-01-01

    Abstract Even though most consumers hold positive attitudes towards organic food, attitudes appear to translate into respective behaviour to the same extent. It has been found that the high and availability are major reasons for this attitude–behaviour gap, especially among young consumers....... In Denmark, supermarkets offer a comparatively broad organic foodrange at relatively small price premiums; however, even in Denmark, market growth ratesare moderate. To explore in detail young consumer’s barriers to act upon their attitudes, we aimed at researching their thoughts and product associations...

  4. Haemonchotolerance in West African Dwarf goats: contribution to sustainable, anthelmintics-free helminth control in traditionally managed Nigerian dwarf goats

    Chiejina, Samuel N.; Behnke, Jerzy M.; Fakae, Barineme B.

    2015-01-01

    West African Dwarf (WAD) goats are extremely important in the rural village economy of West Africa, but still little is known about their biology, ecology and capacity to cope with gastrointestinal nematode (GIN) infections. Here, we summarise the history of this breed and explain its economic importance in rural West Africa. We review recent work showing that Nigerian WAD goats are highly trypanotolerant and resist infections with Haemonchus contortus more effectively than other breeds of domestic goat (haemonchotolerance). We believe that haemonchotolerance is largely responsible for the generally low level GIN infections and absence of clinical haemonchosis in WADs under field conditions, and has contributed to the relatively successful and sustainable, anthelmintics-free, small-scale system of goat husbandry in Nigeria’s humid zone, and is immunologically based and genetically controlled. If haemonchotolerance can be shown to be genetically controlled, it should be possible to exploit the underlying genes to improve GIN resistance among productive fibre and milk producing breeds of goats, most of which are highly susceptible to nematode infections. Genetic resistance to GIN and trypanosome infections would obviate the need for expensive chemotherapy, mostly unaffordable to small-holder farmers in Africa, and a significant cost of goat husbandry in more developed countries. Either introgression of resistance alleles into susceptible breeds by conventional breeding, or transgenesis could be used to develop novel parasite-resistant, but highly productive breeds, or to improve the resistance of existing breeds, benefitting the local West African rural economy as well as global caprine livestock agriculture.

  6. Product differentiation among health maintenance organizations: causes and consequences of offering open-ended products.

    Wholey, D R; Christianson, J B

    1994-01-01

    Open-ended products that allow an HMO enrollee to use providers who are not affiliated with the HMO have become an important component of the Clinton administration's health reform proposal, because these products maintain consumer freedom of choice of any provider. However, little is known about the consequences of offering an open-ended product from an organizational standpoint. This paper uses a theory of "spatial competition" to examine the decisions of health maintenance organizations to offer an open-ended product and the effect of offering an open-ended product on their enrollment.

    2018-10-30

    An authentication procedure for differentiating between organic and non-organic cattle production on the basis of analysis of serum samples has been developed. For this purpose, the concentrations of fourteen mineral elements (As, Cd, Co, Cr, Cu, Fe, Hg, I, Mn, Mo, Ni, Pb, Se and Zn) in 522 serum samples from cows (341 from organic farms and 181 from non-organic farms), determined by inductively coupled plasma spectrometry, were used. The chemical information provided by serum analysis was employed to construct different pattern recognition classification models that predict the origin of each sample: organic or non-organic class. Among all classification procedures considered, the best results were obtained with the decision tree C5.0, Random Forest and AdaBoost neural networks, with hit levels close to 90% for both production types. The proposed method, involving analysis of serum samples, provided rapid, accurate in vivo classification of cattle according to organic and non-organic production type.

    Full Text Available Aim: The study was conducted to isolate and identify Dermatophilus congolensis (DC using conventional and molecular diagnostic techniques in scab materials collected from skin infections of sheep and goats in the Delta region of Tamil Nadu. Materials and Methods: A total of 20 scab samples collected from 18 goats and 2 sheep from Nagapattinam, Thanjavur, and Tiruvarur districts of Tamil Nadu. Smears were made from softened scab materials and stained by either Gram's or Giemsa staining. Isolation was attempted on blood agar plates, and colonies were stained by Gram's staining for morphological identification. Identification was also done by biochemical tests and confirmed by 16S rRNA polymerase chain reaction (PCR, followed by sequencing and phylogenetic analysis of the amplified product. Results: The peculiar laddering arrangement of coccoid forms in stained smears prepared from scab materials revealed the presence of DC. Isolated colonies from scab materials of sheep and goats on bovine blood agar plate were small, hemolytic, rough, adherent, and bright orange-yellow in color, but some colonies were white to cream color. Gram-staining of cultured organisms revealed Gram-positive branching filaments with various disintegration stages of organisms. 16S rRNA PCR yielded 500 bp amplicon specific for DC. Sequence analysis of a sheep DC isolate showed 99-100% sequence homology with other DC isolates available in NCBI database, and phylogenetic tree showed a close cluster with DC isolates of Congo, Nigeria, and Angola of Africa. Genes for virulence factors such as serine protease and alkaline ceramidase could not be detected by PCR in any of the DC strains isolated of this study." Conclusion: The presence of dermatophilosis in Tamil Nadu was established from this study.

  10. The Efficiency of Supplementing Mondia Whytei, Maize Germ, Lucerne and Dairy Meal on Feed Intake, milk Production and body Weight Changes in Dual Purpose goats fed on Basal Diet of Rhodes Grass Hay

    Wekesa, F.M.

    2002-01-01

    In order to exploit the productive potential of milk producing animal, supplementation is a prerequisite. However due to low purchasing power of most small scale dairy farmers some farmers use what is locally available as supplements of Mondia whytei, maize germ, lucerne and dairy meal were fed to dual purpose lactating goats in a completely randomised design. The basal diet was Rhodes grass hay. Chemical composition of feeds was done. Crude protein, CP in Mondia leaves was 187 g kg -1 DM while calcium was 69.1 g kg -1 DM. Mondia whytei is a plant which mainly grows in forests and has many valuable uses including its use as a livestock feed. It has been claimed that when farmers in western Kenya feed Mondia roots to their lactating cows there is an increase in milk production. It is against this background that this work was undertaken to compare the potential of Mondia whytei roots and leaves with other conventional feed supplements. Response to Mondia roots was quite low. There was no significant difference in rumen pH levels over time between treatments. It is recommended that more work be done on Mondia whytei to determine its potential as a feed supplement and to continue monitoring its use on-farm including its feeding methods used by farmers in western Kenya

    2010-01-01

    Full Text Available Secondary organic aerosol (SOA production was observed at significant levels in a series of modern diesel exhaust (DE aging experiments conducted at the European Outdoor Photoreactor/Simulation Chamber (EUPHORE. The greatest production occurred in DE with toluene addition experiments (>40%, followed by DE with HCHO (for OH radical generation experiments. A small amount of SOA (3% was observed for DE in dark with N2O5 (for NO3 radical production experiments. The analysis for a limited number (54 of polar organic compounds (POC was conducted to assess the composition of modern DE and the formation of photochemical transformation products. Distinct POC formation in light versus dark experiments suggests the role of OH initiated reactions in these chamber atmospheres. A trend of increasing concentrations of dicarboxylic acids in light versus dark experiments was observed when evaluated on a compound group basis. The four toluene addition experiments in this study were performed at different [tol]o/[NOx]o ratios and displayed an average SOA %yield (in relation to toluene of 5.3±1.6%, which is compared to past chamber studies that evaluated the impact of [tol]o/[NOx]o on SOA production in more simplified mixtures.

    Previous work has shown that products from the chemical degradation of cellulosic matter can significantly reduce sorption of uranium(VI) and plutonium(IV) on geological materials. Uranium(IV) batch sorption experiments have now been performed to study the effect of organic degradation products in a reducing environment. Thorium(IV) sorption has also been studied since thorium is an important radioelement in its own right and has potential use as a simulant for other tetravalent actinides. Sorption onto London clay, Caithness flagstones and St. Bees sandstone was investigated. Experimental conditions were chosen to simulate both those expected close to cementitious repository (pH ∝ 11) and at the edge of the zone of migration of the alkaline plume (pH ∝ 8). Work was carried out with both authentic degradation products and with gluconate, acting as a well-characterized simulant for cellulosic degradation products. The results show that the presence of organic species can cause a reduction in sorption. This is especially so in the presence of a high concentration of gluconate ions, but the reduction is significantly less with authentic degradation products. (orig.)

    Little is known about the production of fluorescent dissolved organic matter (FDOM) in the anoxic oceanic sediments. In this study, sediment pore waters were sampled from four different sites in the Chukchi-East Siberian Seas area to examine the bulk dissolved organic carbon (DOC) and their optical properties. The production of FDOM, coupled with the increase of nutrients, was observed above the sulfate-methane-transition-zone (SMTZ). The presence of FDOM was concurrent with sulfate reduction and increased alkalinity (R2 > 0.96, p  0.95, p CDOM and FDOM to the overlying water column, unearthing a channel of generally bio-refractory and pre-aged DOM to the oceans.

    2009-06-01

    Full Text Available Breeding programs in dairy goats are mainly based on milk production and composition. Murciano-Granadina goats are located principally in the central and southern regions of Spain. This study is focused in Valencia Community (Spain and the objective is to study the Murciano-Granadina livestock based on the database from Murciano-Granadina Goat Breeders Association of Valencia (AMURVAL.  The aim of this study is to analyze the relationship among different variables related with milk production; milk yield, fat, protein, lactose, SCC, the number of births, lactation number and season. This analysis is carried out by using the Self Organizing Map. This tool allows mapping high-dimensional input spaces into much lower-dimensional spaces, thus making much more straightforward to understand any representation of data.

    Full Text Available Sunflower (Helianthus annuus L. is an annual plant native to the Americas. Is a grain-producing species with a high oil content, which can be used as a source of biodiesel as well as fodder. The cassava is a liquid derived from the cassava flour production. This organic waste can be used in agriculture due to its high content of nutrients such as, K, N, P, Ca, Mg and S and also avoiding harm the environment. The objective of this study was to evaluate the productivity of sunflower using organic fertilization with cassava. The experiment was conducted under field conditions at Lagoa Seca, PB State, and were analyzed the total production (PS, dry mass of the inflorescence (FCA, dry mass of seeds and inflorescence (FSC and total dry biomass (FT. The highest yield (934.52 kg ha-1 was obtained with no applied cassava. The dosage of 250 mL of cassava yielded maximum values for dry mass of the inflorescence (2,380 kg ha-1 and dry matter of the seeds and inflorescence (3,432 kg ha-1, promoting a increase of 32.03% and 132.55% respectively when compared to the control treatment. The higher value of total biomass was 28,017 kg ha-1 when applied 375 mL of manipueria. The cassava as a source of organic fertilizer favors the dry matter accumulation of sunflower without raising the grain yield.

    cannot be adjusted in the short run. However, land, labor, and organic fertilizer can neither be traded on a perfect market nor are their quantities completely fixed for cotton production, but these input quantities can be adjusted by adjusting their use for other activities of the household. Hence......Cotton is known as the “white gold” of Africa since it is the only export crop in which the continent’s share in the world market has increased over the past decades. Total cotton production as well as productivity grew particularly in Western and Central Africa. In contrast, cotton production grew...... and output, as well as socio-economic and agronomic factors, but also on the shadow prices of all sparsely traded inputs, i.e. land, labor, and organic fertilizer.

    2006-10-01

    The bacteriocinogenic Enterococcus faecium F58 strain, a natural goat's jben cheese isolate, lacks decarboxylase activity involved in most biogenic amine formation. It was also sensitive to 13 antibiotics assayed and free of virulence and vancomycin resistance genes. The F58 strain reached the stationary phase after 12 h of growth in sterile goat's milk, and the production of enterocin F-58 (Ent L50) was first detected after 48 h (400 AU/ml), thereafter remaining stable up to 5 days. The effectiveness of the F58 strain in controlling Listeria monocytogenes serovar 4b in reduced fat and whole goat's milk, and in goat's jben has been examined. Coculture experiments of F58-L. monocytogenes in both types of milk demonstrated that listeriae were not eliminated, although reductions by 1 to 4 log units were found. Nevertheless, when the F58 strain was previously inoculated in whole milk and left to grow for 12 h before contamination, the pathogen was completely eliminated after 130 h of coculture. Production of jben cheese contaminated with L. monocytogenes prior to packaging, using preparations of F58-producer strain, caused a significant decrease in the number of viable listeriae, which were undetectable after 1 week of cheese storage at 22 degrees C. Altogether, results from this study suggest that E. faecium F58 strain may be used as an adjunct culture in cheese to control contamination and growth of L. monocytogenes by in situ enterocin production, thus providing an additional hurdle to enhance control of this pathogen.

    Full Text Available Seven out of 25 goats from a southern Brazilian flock developed nutritional fibrous osteodystrophy. Affected animals were younger than 1 year of age and were confined in stalls and fed a concentrate ration containing 1:6 calcium:phosphorus ratio. The remaining flock (35 goats was managed at pasture and showed no disease. Clinical signs were characterized by mandibular and maxillary enlargements, varying degrees of mouth opening and protruding tongue, dyspnea, apart of abnormalities of prehension and mastication. Affected animals had increased seric levels of phosphorus and parathormone, as well as higher alkaline phosphatase activity. Postmortem examination on three succumbed goats revealed bilateral enlargement of the maxilla and mandibula, and loose teeth, apart of multiple incomplete rib fractures in one of them. Severe diffuse proliferation of loose connective tissue surrounded the osteoid trabeculae, many of which were partially or completely non-mineralized. Mineralized osteoid trabeculae showed osteoclasts in the Howship's lacunae.

  3. Rice farming in Bali: organic production and marketing challenges.

    MacRae, Graeme

    2011-01-01

    All is not well with agriculture in Southeast Asia. The productivity gains of the Green Revolution have slowed and even reversed and environmental problems and shortages of water and land are evident. At the same time changing world markets are shifting the dynamics of national agricultural economies. But from the point of view of farmers themselves, it is their season-to-season economic survival that is at stake. Bali is in some ways typical of other agricultural areas in the region, but it is also a special case because of its distinctive economic and cultural environment dominated by tourism. In this environment, farmers are doubly marginalized. At the same time the island offers them unique market opportunities for premium and organic produce. This article examines the ways in which these opportunities have been approached and describes their varying degrees of success. It focuses especially on one project that has been successful in reducing production costs by conversion to organic production, but less so in marketing its produce. It argues finally for the need for integrated studies of the entire rice production/marketing complex, especially from the bottom-up point of view of farmers.

  4. Agrobiodiversity Genetic Variability Utilization in Organic Food Production

    2018-03-01

    Full Text Available The food production at the global level is about to meet its border. Industrialization of agriculture correlates with an explosive enlargement of human population, during XX and at the beginning of XXI centuries. An ongoing process of environmental erosion has been speeding up during that period, not only in our physical surrounding, but also in biodiversity. A new direction in agricultural food production is in demand. Organic food production has been recognized as the way of providing safety and quality food, preserving the environment in the same time. In the other hand new land areas have to be explored for agricultural use, in order to enhance food quantity to meeting the increasing demand for food. These targets set new requirements in plant breeding. To fulfill these requirements the genetic variability harbored in genetic resources has to be preserved, examined and put to good use.

    Annual demand for radiopharmaceuticals in Ukraine is about 50.000 GBq and expenses for their purchase are about 1 - 2 mln US dollars per year. It determines expediency of their production in Ukraine. Taking into consideration the fact that one of the aftereffects of the accident at Chernobyl Atomic Power Station is inevitable increase of the number of oncological diseases (including malignant growths of the thyroid gland) the demand for radionuclides will be increasing steadily. Therefore, it is clear that organization of the centre for radiopharmaceuticals production will not solve the problem of providing radiological departments with them. One of the possible ways to solve the problem is creation of a network of regional centres for radioactive isotopes production. Realisation of the suggested program will allow to solve the problem of providing the medical establishments of Ukraine with medical radionuclides. Performed technical and economical evaluation shows that the expenses will be compensated in 2.9 years

    Parasitic infection is recognized worldwide as a limiting factor in the production of goats, and various control methods are used to reduce economic losses, often without considering the epidemiology of the parasites. This has led to the development of highly tolerant parasite populations and the presence of chemical residues in the beef and milk. The objective of this study was to determine the level of knowledge of goat farmers about parasitic diseases and to correlate this with the epidemiology of endoparasites and parasite control practices in goat farms in the state of Minas Gerais, Brazil. The analysis was based on a questionnaire applied by trained veterinarians. The sample was homogeneous throughout the state, covering 18.4% (157/853) of municipalities. Eighty-four dairy goat farms in 81 municipalities and 200 properties with beef goats in 76 municipalities were evaluated. The herd size per goat farm ranged from 4 to 57 (average 24) for beef herds and from 2 to 308 (average 63) for dairy farms. The majority of the beef herd production was extensive and semi-extensive (98.5%), while the dairy herds were maintained under intensive farming (98.8%). The mixed production of goats and sheep was reported by 36.5% of beef goat farmers and by 20.2% of dairy goat farmers. Among the beef goats farms on which the technological level was determined, 2.0% were categorized as having high technological level, 34.5% as medium, and 63.5% as low. Of the 84 dairy farms, 30% operated at a high, 47% at a medium, and 23% at a low technological level. The adoption of practices to reduce parasitism, such as the quarantine of animals, treatment of newly arrived animals, regular cleaning of the floor, and technical assistance, was significantly higher on dairy farms than on beef farms. Although 85.7% of dairy farmers and 83% of beef farmers medicate their animals, the treatments were performed without technical criteria, and deworming intervals ranged from 30 to 120 days or more.

    2014-01-01

    Full Text Available The comparative pharmacokinetic profile of cefquinome was studied in sheep and goats following repeated intramuscular (IM administrations of 2 mg/kg body weight. Cefquinome concentrations in serum were determined by microbiological assay technique using Micrococcus luteus (ATCC 9341 as test organism. Following intramuscular injection of cefquinome in sheep and goats, the disposition curves were best described by two-compartment open model in both sheep and goats. The pharmacokinetics of cefquinome did not differ significantly between sheep and goats; similar intramuscular dose rate of cefquinome should therefore be applicable to both species. On comparing the data of serum levels of repeated intramuscular injections with first intramuscular injection, it was revealed that repeated intramuscular injections of cefquinome have cumulative effect in both species sheep and goats. The in vitro serum protein-binding tendency was 15.65% in sheep and 14.42% in goats. The serum concentrations of cefquinome along 24 h after injection in this study were exceeding the MICs of different susceptible microorganisms responsible for serious disease problems. These findings indicate successful use of cefquinome in sheep and goats.

Esta revisão tem como objetivo avaliar as variações referentes à composição química e propriedades físicoquímicas do leite, que ocorrem em função de alguns fatores, tais como: climáticos, raça, indivíduo, estágio de lactação e alimentação. O manejo alimentar tem sido considerado um fator preponderante na manipulação dos componentes do leite. Há um entendimento dominante que a gordura é o componente do leite que mais sofre influência dos alimentos. O uso de técnicas biológicas moleculares poderá contribuir para o entendimento do mecanismo de utilização do alimento no rúmen, estabelecendo um novo cenário para a microbiologia ruminal, que pode ser diferente do que tem sido estudado até o momento.Goat milk is considered one of the most complete foods, since it holds several elements which are important for human nutrition, and necessary for the constitution of tissues and blood. This revision aims to assess the variations of the chemical composition and physical-chemical properties of the milk which occur due to some factors, such as: climate, breed, the individual, lactation stage and food. Feed management has been considered a key factor in the manipulation of milk components. There is a general understanding that among the components of the milk fat is the most influenced by food. The use of molecular biological techniques might contribute to the understanding of the mechanism of utilization of food in rumen, establishing a new possibility for ruminal microbiology, which can be different from what has been studied so far.

    This study was conducted to determine the physical and chemical composition of goat milk produced by eight local farms located in the central region of Malaysia. Farms 1 to 4 (F1-SC, F2-SP, F3-SP, F4-SBC) reared Saanen-type goats while farms 5 to 8 (F5-JK, F6-JPEC, F7-JTC, F8-JC), Jamnapari-type goats. The common feedstuffs used in all farms comprised of fresh or silage from Napier grass, feed pellets, and brans while two farms, F5-JK and F6-JPEC supplemented the feeds with soybean-based product. The total solid content, dry matter, and proximate composition of goat milk and feedstuffs from the different farms were determined and the results analysed using principal component analysis. Total solid content of goat milk from the Jamnapari crossbreed had the highest solid content ranging from 11.81% to 17.54% compared to milk from farms with Saanen and Saanen crossbreed (10.95% to 14.63%). Jamnapari-type goats from F5-JK, F6-JPEC, and F8-JC had significantly higher ( p milk fat and protein contents (7.36%, 7.14%, and 6.59% fat; 5.08%, 6.19%, and 4.23% protein, respectively) than milk from other farms but, milk produced by Saanen-type goats from F4-SBC contained similar protein content (4.34%) to that from F8-JC. Total ash and carbohydrate contents in milk ranged between 0.67% to 0.86% and 3.26% to 4.71%, respectively, regardless of goat breed. Feeding soybean-based products appear to have a positive influence on milk fat and protein content in Jamnaparitype goats.

  13. GOATS - Orbitology Component

    Haber, Benjamin M.; Green, Joseph J.

    2010-01-01

    The GOATS Orbitology Component software was developed to specifically address the concerns presented by orbit analysis tools that are often written as stand-alone applications. These applications do not easily interface with standard JPL first-principles analysis tools, and have a steep learning curve due to their complicated nature. This toolset is written as a series of MATLAB functions, allowing seamless integration into existing JPL optical systems engineering modeling and analysis modules. The functions are completely open, and allow for advanced users to delve into and modify the underlying physics being modeled. Additionally, this software module fills an analysis gap, allowing for quick, high-level mission analysis trades without the need for detailed and complicated orbit analysis using commercial stand-alone tools. This software consists of a series of MATLAB functions to provide for geometric orbit-related analysis. This includes propagation of orbits to varying levels of generalization. In the simplest case, geosynchronous orbits can be modeled by specifying a subset of three orbit elements. The next case is a circular orbit, which can be specified by a subset of four orbit elements. The most general case is an arbitrary elliptical orbit specified by all six orbit elements. These orbits are all solved geometrically, under the basic problem of an object in circular (or elliptical) orbit around a rotating spheroid. The orbit functions output time series ground tracks, which serve as the basis for more detailed orbit analysis. This software module also includes functions to track the positions of the Sun, Moon, and arbitrary celestial bodies specified by right ascension and declination. Also included are functions to calculate line-of-sight geometries to ground-based targets, angular rotations and decompositions, and other line-of-site calculations. The toolset allows for the rapid execution of orbit trade studies at the level of detail required for the

    Full Text Available Background: Obesity and cardiovascular heart diseases are growing problems in the United States. This is partially due to the consumption of the primary red meats such as pork and beef. Goat meat has the potential to replace these traditionally consumed meats. Rice bran is a rich source of antioxidants such as vitamin E and can be utilized as a binder in meat and meat products. Methods: Goat meat/beef sausages were formulated to contain either 50/50, 75/25 or 100/0 percent goat meat/beef, with either no added rice bran (NRB or 3 percent stabilized rice bran (RB. Proximate analysis, fatty acids, -tocopherol and cholesterol concentrations of the six cooked formulations were determined. The six sausage formulations were compared in a consumer acceptability taste test. Results: The fat concentration of the NRB and RB formulations decreased linearly with increasing percentages of goat meat (p < 0.001. The sum of the saturated fatty acids decreased linearly with increasing percentages of goat meat (p < 0.01. Polyunsaturated fatty acids, omega-3 and omega-6 fatty acid and conjugated linoleic acid concentrations increased linearly (p < 0.05 with increasing percentages of goat meat in both the NRB and RB sausage formulations. The α-tocopherol concentration of the NRB formulations did not change across the goat meat percentages, but in the RB formulations it increased linearly with increasing percentages of goat meat (p < 0.001. The cholesterol concentration decreased linearly with increasing percentages of goat meat in both the NRB and RB formulations (p <0.01, < 0.05 respectively. The tasters preferred the NRB with higher goat meat percentage to the RB formulations. Conclusions: The NRB and RB sausage formulations with higher percentages of goat meat had higher concentrations of -tocopherol, CLA (18:2 cis 9 Trans 11, total n-3, total PUFA, total n-3/total n-6 ratio, and a lower cholesterol concentration.

  18. Soil biota and agriculture production in conventional and organic farming

    Schrama, Maarten; de Haan, Joj; Carvalho, Sabrina; Kroonen, Mark; Verstegen, Harry; Van der Putten, Wim

    2015-04-01

    Sustainable food production for a growing world population requires a healthy soil that can buffer environmental extremes and minimize its losses. There are currently two views on how to achieve this: by intensifying conventional agriculture or by developing organically based agriculture. It has been established that yields of conventional agriculture can be 20% higher than of organic agriculture. However, high yields of intensified conventional agriculture trade off with loss of soil biodiversity, leaching of nutrients, and other unwanted ecosystem dis-services. One of the key explanations for the loss of nutrients and GHG from intensive agriculture is that it results in high dynamics of nutrient losses, and policy has aimed at reducing temporal variation. However, little is known about how different agricultural practices affect spatial variation, and it is unknown how soil fauna acts this. In this study we compare the spatial and temporal variation of physical, chemical and biological parameters in a long term (13-year) field experiment with two conventional farming systems (low and medium organic matter input) and one organic farming system (high organic matter input) and we evaluate the impact on ecosystem services that these farming systems provide. Soil chemical (N availability, N mineralization, pH) and soil biological parameters (nematode abundance, bacterial and fungal biomass) show considerably higher spatial variation under conventional farming than under organic farming. Higher variation in soil chemical and biological parameters coincides with the presence of 'leaky' spots (high nitrate leaching) in conventional farming systems, which shift unpredictably over the course of one season. Although variation in soil physical factors (soil organic matter, soil aggregation, soil moisture) was similar between treatments, but averages were higher under organic farming, indicating more buffered conditions for nutrient cycling. All these changes coincide with

  19. Production of Dissolved Organic Matter During Doliolid Feeding

    Castellane, N. J.; Paffenhofer, G. A.; Stubbins, A.

    2016-02-01

    The biological carbon pump (BCP) draws carbon dioxide out of the atmosphere and buries it at the seafloor. The efficiency of the BCP is determined in part by the sinking rates of particulate organic carbon (POC) from ocean surface waters. Zooplankton can package POC into fecal pellets with higher sinking rates than their food source (e.g. phytoplankton), increasing the efficiency of the BCP. However, dissolved organic carbon (DOC) is also produced as zooplankton ingest and egest food, reducing the efficiency of BCP. The pelagic tunicate Dolioletta gegenbauri (doliolid) is a gelatinous zooplankton found at high concentrations in shelf waters, including our study site: the South Atlantic Bight. Doliolids are efficient grazers capable of stripping large quantities of phytoplankton from the water column. To determine the balance between pellet formation and DOC production during feeding, doliolids (6-7 mm gonozooids) were placed in natural seawater amended with a live phytoplankton food source and incubated on a plankton wheel. Dissolved organic matter (DOM) released directly to the water as well as the water soluble fraction of pellet organic matter were quantified and optically characterized. Colored dissolved organic matter (CDOM) absorbance and fluorescence spectra revealed that doliolid feeding produces DOM with optical properties that are commonly indicative of newly produced, highly biolabile DOM of microbial origin. Based upon these optical characteristics, doliolid-produced DOM is expected to be highly bio-labile in the environment and therefore rapidly degraded by surface ocean microbes shunting phytoplankton-derived organic carbon out of the BCP and back to dissolved inorganic carbon.

  20. Analysis of weed flora in conventional and organic potato production

    Nikolić, Lj.

    2013-12-01

    Full Text Available Composition of weed flora is highly dynamic and depends upon great number of factors, of which cultural practices that are applied by humans in certain crops are the most important. One of the most frequently grown plants in the world and in our country is potato (Solanum tuberosum L., Solanaceae, due to its high biological and nutritive value. Therefore, in the paper was presented taxonomic analysis of weed flora in potato grown conventionally and according to the principles of organic agricultural production, with the intention to point out to eventual differences between present weeds. Of the total number of identified species, from phylum Equisetophyta and class Equisetopsida, in organic potato crop, was determined only one, Equisetum arvense. Of remaining 38 weeds from phylum Magnoliophyta., classified into two classes, Magnoliopsida and Liliopsida. On both of potato growing systems, 39 weed species were found, classified into 16 families and 32 genus. Of the total number, 31 species was identified in conventional potato crop, and only 23 species in potato crop grown according to organic principles, which is for about quarter less. Biological spectrum of weed flora in both potato growing systems is pronouncedly of terrophytic – geophytic type. In the spectrum of area types were recorded differences, i.e. in the conventional potato crop represented are only widely distributed species, while in the organic crop, beside species of wide distribution are also present elements of Pontic group.

    Full Text Available A study was conducted in order to evaluate the contamination by Brucella spp. of meat from animals slaughtered because they had resulted positive for brucellosis at some time during their life. After slaughter and before delivery to market outlets, swab samples were taken from 307 carcasses of infected animals: 40 cattle, 60 sheep and 207 goats. The swabs were subsequently analysed by means of polymerase chain reaction (PCR tests. In addition, bacteriological tests were carried out on the lymph nodes and internal organs of the same animals. Brucella spp. was detected by means of PCR in 25/307 carcasses (8%: 1 bovine (2.5%, 9 sheep (15% and 15 goats (7.2% and was isolated by means of a cultural method in 136/307 carcasses (44%. Moreover, additional analysis, performed on lymph nodes from the same carcasses that had proved positive by PCR, allowed highlighting type 3 Brucella abortus in the bovine carcass and type 3 Brucella melitensis in the sheep and goat carcasses. The study shows that cattle, sheep and goats meat of animals slaughtered because they had tested positive for brucellosis may be contaminated by Brucella spp. As this could constitute a real risk of transmission to both butchery personnel and consumers, the meat of animals infected by Brucella spp. should be analysed before being marketed. In this respect, PCR technique performed on swabs proved to be more useful, practical and faster than the traditional bacteriological method.

    Examine the effects of supplementing bahiagrass hay (BG) with potentially anthelmintic quantities of hays of perennial peanut (PEA) or sericea lespedeza (LES) or seeds of velvet bean ( Mucuna pruriens L.; MUC) or papaya (PAP) on the intake and nutritive value (Experiment 1), and the performance and parasite burden (Experiment 2) of goats. In Experiment 1, 38 male goats (27.4±5.7 kg body weight) were randomly assigned to each of 5 treatments: i) BG alone and BG plus; ii) PEA; iii) LES; iv) MUC; and v) PAP. Goats were fed for ad libitum consumption and adapted to the diets for 14 d followed by 7 d of measurement. The PEA, LES, MUC (50%, 50%, and 10% of the diet dry matter [DM], respectively), and PAP (forced-fed at 10 g/d) were fed at rates that would elicit anthelmintic effects. In Experiment 2, goats remained in the same treatments but were allocated to 15 pens (3 pens per treatment) from d 22 to 63. All goats were infected with parasites by grazing an infected bahiagrass pasture from 0800 to 1500 h daily and then returned to the pens. Dry matter intake tended to be greater in goats fed PEA and LES than those fed BG (757 and 745 vs 612 g/d, respectively). Digestibility of DM (59.5% vs 54.9%) and organic matter (60.8% vs 56.0%) were greater in goats fed MUC vs BG, respectively. In Experiment 2, feeding PAP, LES, and PEA to goats reduced nematode fecal egg counts by 72%, 52%, and 32%, reduced abomasal adult worm counts by 78%, 52%, and 42%, and decreased plasma haptoglobin concentrations by 42%, 40%, and 45% relative to feeding BG alone, respectively. Supplementation with PEA, LES, and PAP decreased the parasite burden of goats but did not increase their performance. PAP was the most effective anthelmintic supplement.

  4. Organic livestock production: an emerging opportunity with new challenges for producers in tropical countries.

    Chander, M; Subrahmanyeswari, B; Mukherjee, R; Kumar, S

    2011-12-01

    Agrochemicals, veterinary drugs, antibiotics and improved feeds can increase the food supply while minimising production costs in various livestock production systems around the world. However, these days, quality-conscious consumers are increasingly seeking environmentally safe, chemical-residue-free healthy foods, along with product traceability and a high standard of animal welfare, which organic production methods are said to ensure. Organic production is not only a challenge for producers in developing countries, it offers new export opportunities as well. Organic agriculture is practised by 1.8 million producers in 160 countries, and production of organically grown food continues to increase steadily by 15% per year. Most tropical countries are now exporting organic agricultural products but, apart from organic beef from Brazil and Argentina, organic livestock products are yetto take off. Most trade in organic livestock products is restricted to the European Union and other developed nations. Nevertheless, tropical countries cannot afford to neglect this emerging system of animal production. Organic production is knowledge- and management-intensive. Producers must be well versed in organic production standards, principles and practices, which require a high degree of knowledge and skill. In organic production, it is not simply the final product but the whole production process that must be inspected and approved by the accredited certification bodies. Organic livestock farming is still evolving, and further research is needed to make it sustainable. In this paper, the authors review the prospects of organic animal husbandry and its possible constraints in developing and tropical countries.

  7. Leadership and productivity in planning organizations: a case study.

    Whitcomb, G R; Williams, E G

    1978-01-01

    This paper presents the findings of a case study dealing mainly with the effects of two divergent leadership styles on the productivity of a planning organization. Changes in various kinds of participation in the agency's activities--an important side effect--are also linked to the two leadership patterns. The agency studied, a private health and welfare council in a medium-sized American city, varied considerably in its output of planning activities and decision making depending on whether it had a participative or a directive leader. The results indicated that there was a trade-off between such highly revered social values as leadership and the extent of participation by staff, board members, and local agency administrators. Implications focus on ways to achieve diversity in communication style among managers and the role of productivity measures in determining the overall effectiveness of planning agencies.

    Mdladla, Khanyisile; Dzomba, Edgar F; Muchadeyi, Farai C

    2016-03-01

    The present study investigated the seroprevalence of antibodies to Ehrlichia ruminantium and the associated risk factors in goats from five different farming provinces of South Africa. Sera collected from 686 goats of the commercial meat type (n=179), mohair type (n=9), non-descript indigenous goats from Eastern Cape (n=56), KwaZulu-Natal (n=209), Limpopo (n=111), North West (n=61) and Northern Cape (n=11) provinces and a feral Tankwa goat (n=50) were tested for the presence of immunoglobulin G (IgG) antibodies to antigens of E. ruminantium using the indirect fluorescent-antibody test (IFAT). Fifty two percent of these goats had ticks. The overall seroprevalence of antibodies to E. ruminantium was 64.87% (445/686) with the highest seroprevalence reported for Limpopo (95.50%) and lowest for Northern Cape (20.29%). Highest seroprevalence for antibodies to E. ruminantium was observed in goats from endemic regions (76.09%), and from smallholder production systems (89.54%). High seroprevalence was also observed in non-descript indigenous goats (85.04%), adult goat (69.62%), in does (67.46%) and goats infested with ticks (85.79%). The logistic model showed a gradient of increasing risk for commercial meat type Savanna (OR=3.681; CI=1.335-10.149) and non-descript indigenous (OR=3.466; CI=1.57-7.645) compared to Boer goats and for goats from the smallholder production system (OR=2.582; CI=1.182-5.639) and those with ticks (OR=3.587; CI=2.105-6.112). Results from this study showed that E. ruminantium infections were prevalent but were widely and unevenly distributed throughout South Africa. Findings from the study facilitate identification and mapping of risk areas for heartwater and its endeminicity in South Africa and should be taken into consideration for future disease control strategies and local goat improvement programs.

  11. Production of volatile organic compounds by cyanobacteria Synechococcus sp.

    Hiraiwa, M.; Abe, M.; Hashimoto, S.

    2014-12-01

    Phytoplankton are known to produce volatile organic compounds (VOCs), which contribute to environmental problems such as global warming and decomposition of stratospheric ozone. For example, picophytoplankton, such as Prochlorococcus and Synechococcus, are distributed in freshwater and oceans worldwide, accounting for a large proportion of biomass and primary production in the open ocean. However, to date, little is known about the production of VOCs by picophytoplankton. In this study, VOCs production by cyanobacteria Synechococcus sp. (NIES-981) was investigated. Synechococcus sp. was obtained from the National Institute for Environmental Studies (NIES), Japan, and cultured at 24°C in autoclaved f/2-Si medium under 54 ± 3 µE m-2 s-1 (1 E = 1 mol of photons) with a 12-h light and 12-h dark cycle. VOCs concentrations were determined using a purge-and-trap gas chromatograph-mass spectrometer (Agilent 5973). The concentrations of chlorophyll a (Chl a) were also determined using a fluorometer (Turner TD-700). Bromomethane (CH3Br) and isoprene were produced by Synechococcus sp. Isoprene production was similar to those of other phytoplankton species reported earlier. Isoprene was produced when Chl a was increasing in the early stage of the incubation period (5-15 days of incubation time, exponential phase), but CH3Br was produced when Chl a was reduced in the late stage of the incubation period (30-40 days of incubation time, death phase).

  12. An evolutionary sensor approach for self-organizing production chains

    Mocan, M.; Gillich, E. V.; Mituletu, I. C.; Korka, Z. I.

    2018-01-01

    Industry 4.0 is the actual great step in industrial progress. Convergence of industrial equipment with the power of advanced computing and analysis, low-cost sensing, and new connecting technologies are presumed to bring unexpected advancements in automation, flexibility, and efficiency. In this context, sensors ensure information regarding three essential areas: the number of processed elements, the quality of production and the condition of tools and equipment. To obtain this valuable information, the data resulted from a sensor has to be firstly processed and afterward used by the different stakeholders. If machines are linked together, this information can be employed to organize the production chain with few or without human intervention. We describe here the implementation of a sensor in a milling machine that is part of a simple production chain, capable of providing information regarding the number of manufactured pieces. It is used by the other machines in the production chain, in order to define the type and number of pieces to be manufactured by them and/or to set optimal parameters for their working regime. Secondly, the information achieved by monitoring the machine and manufactured piece dynamic behavior is used to evaluate the product quality. This information is used to warn about the need of maintenance, being transmitted to the specialized department. It is also transmitted to the central unit, in order to reorganize the production by involving other machines or by reconsidering the manufacturing regime of the existing machines. A special attention is drawn on analyzing and classifying the signals acquired via optical sensor from simulated processes.

    The composition of bioactive components in dairy products depends on their content in raw milk and the processing conditions. The experimental material consisted of the milk of dairy goats supplemented with 120 g d(-1) per head of false flax cake. The aim of the study was to evaluate the quality of kefir produced from goat's milk with a higher content of bioactive components resulting from supplementation of the goats' diet with false flax cake. The administration of false flax cake to goats had a positive effect on the fatty acid profile of the raw milk, causing an increase in the proportion of polyunsaturated fatty acids (PUFA), including conjugated linoleic acid (CLA) and n-3 fatty acids. Their increased percentage was detected in the kefir after production as well as after storage. The processing value of the harvested milk did not differ from the qualitative characteristics of milk from goats of the control group. Increasing the proportion of bioactive components in goat's milk did not result in changes in the acidity, texture, colour, flavour, aroma or consistency of the kefir obtained. Milk and kefir obtained after the administration of false flax cake to goats contain bioactive components (PUFA including CLA, n-3 and monoenic trans fatty acids) in significant amounts. Kefir from experimental goat's milk did not differ in quality from kefir made from the milk of the control group. © 2014 Society of Chemical Industry.

  14. Reference Gene Screening for Analyzing Gene Expression Across Goat Tissue

    2013-12-01

    Full Text Available Real-time quantitative PCR (qRT-PCR is one of the important methods for investigating the changes in mRNA expression levels in cells and tissues. Selection of the proper reference genes is very important when calibrating the results of real-time quantitative PCR. Studies on the selection of reference genes in goat tissues are limited, despite the economic importance of their meat and dairy products. We used real-time quantitative PCR to detect the expression levels of eight reference gene candidates (18S, TBP, HMBS, YWHAZ, ACTB, HPRT1, GAPDH and EEF1A2 in ten tissues types sourced from Boer goats. The optimal reference gene combination was selected according to the results determined by geNorm, NormFinder and Bestkeeper software packages. The analyses showed that tissue is an important variability factor in genes expression stability. When all tissues were considered, 18S, TBP and HMBS is the optimal reference combination for calibrating quantitative PCR analysis of gene expression from goat tissues. Dividing data set by tissues, ACTB was the most stable in stomach, small intestine and ovary, 18S in heart and spleen, HMBS in uterus and lung, TBP in liver, HPRT1 in kidney and GAPDH in muscle. Overall, this study provided valuable information about the goat reference genes that can be used in order to perform a proper normalisation when relative quantification by qRT-PCR studies is undertaken.

    Anthelmintic resistance against commonly used anthelmintic fenbendazole was evaluated by employing faecal egg count reduction test (FECRT) in naturally occurring gastrointestinal (GI) nematodes in the semi organized sheep and goat farms of Ludhiana and Amritsar districts. A total of 80 animals (20 each for sheep and goat in both districts) were randomly selected and their faecal samples were examined by qualitative and quantitative parasitological techniques. Results indicate presence of high level of resistance against fenbendazole in both sheep and goat population of Ludhiana and Amritsar districts. More resistance was observed in the GI nematodes from animals reared in Amritsar district as compared to Ludhiana district. The level of anthelmintic resistance observed was apparently more in sheep than goats.

  1. Prevalence and risk factors associated with gastrointestinal nematode infection in goats raised in Baybay city, Leyte, Philippines

    Ariel Paul M. Rupa

    2016-07-01

    Full Text Available Aim: Gastrointestinal parasitism is a serious constraint affecting goat production in the Philippines. This study aimed to determine the prevalence and associated risk factors of gastrointestinal nematode infection in goat-populated barangays of Baybay City, Leyte. Materials and Methods: A total of 81 households or farms were interviewed, and 450 goats were sampled for fecalysis. Fecal egg count along with egg morphological identification and coproculture for third stage larvae identification were conducted. Descriptive statistics and logistic regression analyses were carried out to determine the farm- and animal-level prevalence and risk factors. Results: Fecalysis revealed the presence of strongyle and Trichuris spp. with a farm-level prevalence of 100% and 4.94%, respectively; and animal-level prevalence of 96.22% and 4.44%, respectively. The identified strongyle genera per barangay were Haemonchus spp. (34.79%, Trichostrongylus spp. (33.29%, Oesophagostomum spp. (24.21%, Cooperia spp. (6.93%, and Chabertia spp. (0.79%. Goats older than 12 months were four times more likely to present high strongyle burden when compared to goats <6 months. With each month increase in goat’s age, the odds of acquiring strongyle infection also increased by 1.07 times. Animals kept in goat house with cemented flooring have lower odds of acquiring strongyle (odds ratio=0.12. Goats raised for leisure purposes and fed with carabao grass (Paspalum conjugatum were 8.12 and 5.52 times more likely to acquire Trichuris, respectively. Conclusion: Most of the backyard goat raisers in Baybay City, Leyte, do not practice sound helminth control measures as shown by the high prevalence of gastrointestinal nematodes. The most relevant risk factors for gastrointestinal nematode infection were the age of the goat, type of goat house’s flooring, purpose of raising goats, and feeding practices.

  2. Production of fungal volatile organic compounds in bedding materials

    2008-12-01

    Full Text Available The high relative humidity of the air and many potential growth media, such as bedding materials, hay and grains in the horse stable, for example, provide suitable conditions for fungal growth. Metabolic activity of four common agricultural fungi incubated in peat and wood shavings at 25°C and 4°C was characterized in this study using previously specified volatile metabolites of micro-organisms and CO 2 production as indicators. The volatile organic compounds were collected into Tenax resin and analysed by gas chromatography. Several microbial volatile organic compounds (MVOCs, e.g. 1-butanol, 2-hexanone, 2-heptanone, 3-octanone, 1-octen-3-ol and 1-octanol were detected in laboratory experiments; however, these accounted for only 0.08-1.5% of total volatile organic com-pounds (TVOCs. Emission rates of MVOCs were 0.001-0.176 mg/kg of bedding materials per hour. Despite some limitations of the analytical method, certain individual MVOCs, 2-hexanone, 2-hep-tanone and 3-octanone, were also detected in concentrations of less than 4.6 mg/m 3 (0.07-0.31% of TVOC in a horse stable where peat and shavings were used as bedding materials. MVOC emission rate was estimated to be 0.2-2.0 mg/kg ´ h -1 from bedding materials in the stable, being about ten times higher than the rates found in the laboratory experiments. Some compounds, e.g. 3-octanone and 1-octen-3-ol, can be assumed to originate mainly from microbial metabolisms.;

    Mohammadabadi, Tahereh; Jolazadeh, Alireza

    2017-08-01

    This study investigated the effect of replacing alfalfa hay by subabul leaf meal (SLM) on digestion, fermentation parameters and rumen bacteria and fungi activity of Najdi goats. Six Najdi goats (150 ± 15 days of age and initial body weight of 35 ± 1.1 kg) were randomly assigned to one of two dietary treatments in a balanced completely randomized design (three goats per treatment) for 56 days. Experimental treatments included alfalfa hay as control group and diet containing SLM (SLM replacing alfalfa hay at 50% level). Bacterial and fungi activity and rumen fermentation parameters of animals fed experimental diets were determined. Dry matter disappearance (DMD) was unaffected by replacing SLM with alfalfa hay for both rumen bacteria and fungi in different incubation times, except for 48 h of incubation in specific culture medium of mixed rumen bacteria, which decreased for SLM group (P > 0.05). NDF disappearance (NDFD) and ADF disappearance (ADFD) after 24 and 48 h of incubation in specific culture medium of mixed rumen bacteria was not affected by experimental diets (P > 0.05). However, 72 h after incubation, NDFD in SLM treatment decreased (P > 0.05). Gas production parameters of rumen bacteria were similar for both experimental diets, but partitioning factor (PF), efficiency microbial biomass production (EMBP), microbial protein production (MP), and organic matter truly digested (OMTD) decreased (p alfalfa hay by SLM had no major effect on rumen microorganisms' activity of Najdi goats, so it may be used as an alternative for alfalfa (at 50% level) in susceptible areas.

  4. Farm Organization, Ownership and Food Productivity in Nigeria

    2012-06-01

    Full Text Available African food production is in crisis. Today, despite Africa’s vast physical and climatic potentials to produce food, most African States depend on food importation. Africa’s capacity to deal with its food battles is severely constrained by its political instability, its early stage of scientific and institutional development, and a rapidly changing and complex global environment. In Nigeria and in most developing economies, there is a fundamental lack of political commitment to come grips with poverty, malnutrition and access to food. Because of these barriers, traditional economics is a rather limited tool to understand food production and other related variables. Poverty, hunger, malnutrition, famine and starvation in developing economies are just as much a function of political, macroeconomic, and institutional barriers as lack of technology. Illustrations from the agrarian chaos in Sudan, Ethiopia, Somalia, Chad and others are too numerous to conclude otherwise. The aim of this paper is to determine and analyze economics incentives and strategies, which could stimulate commercial agriculture in Nigeria. The analysis is based on the premise that the form of production organization in Nigerian agriculture is the major constraint to commercialization. The paper concludes that output price subsidy is the over-riding factor in the commercialization of agriculture in Nigeria.

    Full Text Available The usage of locally available forages such as agricultural by-products and native trees is the crucial thing for goat farmers to obtain good quality feed and to reduce cost of feeding. A study was conducted to investigate the performance of crossbred goats fed urea treated rice straw supplemented with different levels of Klienhovia hospita foliage, in particular to determine the nutrient feeding value of experimental feed diets, evaluate the growth performance, feed intake and digestibility of the diets by goats. The feeding trial conducted was divided into two sections: digestibility and animal performance. The digestibility test was performed using total faecal collection method. The treatment diets were based on urea treated rice straw (RS supplemented with commercial concentrate (C and Klienhovia hospita (KH herbage: T1 with 85% RS and 15% C, T2 with 85% RS and 5% KH and 10% C, T3 with 85% RS, 10% KH and 5% C, and T4 with 85% RS and 15% KH. The feeding trial used 12 6-mo old crossbred male goats divided into 4 groups with the diets offered ad libitum and had access to clean drinking water. The left over feed was removed and weighed daily to determine voluntary DM intake. The initial average body weight of goats used ranged between 20.14�1.03 kg and 20.29�0.18 kg. The animals were placed in individual metabolic crates on slatted floor of 0.8 m above ground for 100 consecutive d. The results showed that there was no significant difference observed on body weight of goats among the treatments. ADG of goats was significantly higher in goats on diets T3 and T4 than those on control diet. Significant higher feed intake was observed in goats fed diet containing KH foliage than those fed with diet T1. Results for ASH, CP and ADF digestibility among different treatments were not significantly different whereas NDF digestibility was significantly higher in T2 treatment in comparison with T1, T3 and T4. The dry matter digestibility values of T1

    Sustainable meat goat production begins with the identification and use of maternal breeds that demonstrate relatively enhanced levels of fitness under less-than-optimal conditions. The Myotonic goat is a heritage breed that is lacking in comparative assessment for female fitness. In this study, Boer ( = 73), Kiko ( = 115), Myotonic ( = 80), and Spanish ( = 114) meat goat does were compared for traits associated with health and reproduction. The herd was semi-intensively managed on humid subtropical pasture for 6 yr. The study included 838 doe-year matings and over 2,000 records for BW, fecal egg count (FEC), and packed cell volume (PCV). Body weights of Boer and Kiko does were heavier ( meat goat doe performance under limited-input management conditions. Myotonic does maintained the lowest FEC among all doe breeds and warrant further evaluation as a genetic resource for controlling gastrointestinal parasitism.

  7. Morphological measurements and body indices for Cuban Creole goats and their crossbreds

    Edilberto Chacón

    2011-08-01

    Full Text Available In this work, linear body measures were taken and production indices calculated for 100 Cuban Creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in Cuba. Low variation was found for all indices of the Creole goats, showing homogeneity between the groups of animals studied. Most of the functional indices are related to the milk biotype which is in agreement the possible origin of the breed from animals of the Iberian Peninsula and Canary Islands. The crossbreds were more varied, mostly due to undesigned disorganized crossing. These data may help in identifying a commercial niche for the breed and contribute to in situ conservation of the Cuban Creole goat.

    The prevalence of Campylobacter jejuni and Campylobacter coli was determined in goat and goat meat sold at retail outlets in Lubumbashi, Democratic Republic of Congo (DR Congo). A total of 644 samples, including 177 goat meat, 86 goat stomachs, 139 ready to eat (RTE) goat skewers, and 242 goat faecal samples were examined for the presence of Campylobacter jejuni and Campylobacter coli using polymerase chain reaction. Overall, Campylobacter spp. were found in 34.6% of the examined samples. C. jejuni was isolated in 10.1% and C. coli in 26.7% of samples. Only 2.2% of all samples were positive for both species. There was a significant association between the prevalence of C. coli and the type of sample (p goat meat, goat stomachs, RTE goat skewers, and goat faecal samples, respectively. There was no significant difference (p > 0.05) between the prevalence observed in the rainy season (16.7%) and the dry season (20.0%). Moreover, the overall prevalence of Campylobacter in slaughter sites, open-air markets, warehouses, and semi-open-air markets was 28.2%, 34.2%, 35.4%, and 42.9%, respectively. Statistically, there was no influence of the sample collection site on the frequency of isolation of Campylobacter (p > 0.05). This study shows that, considering the relatively high prevalence of this pathogen, live goat and goat meat are major sources of human and environmental contamination by Campylobacter spp. in Lubumbashi.

    Full Text Available Production systems influence crops differently, mainly in terms of yield. However, there are few studies that have evaluated different bushing snap bean genotypes in different systems. Thus, this study aimed to evaluate the production components and yield of bushing snap beans in conventional and organic production systems. The experimental design was a randomized complete block, in a factorial 6 × 2 arrangement, corresponding to six genotypes and two production systems, with three replications. The genotypes Isla Manteiga Baixo®, Isla Macarrão Baixo®, Feltrin Vicenza Amarelo Baixo®, and Feltrin Macarrão Napoli®, UEL 1, and UEL 2 were submitted to the following determinations: days to flowering; plant height; medium number of pods per plant; average pod mass, length, and diameter; and yield of commercial pods. A joint analysis of variance was conducted by applying the F test, with mean comparison performed using the Tukey’s test (p < 0.05. Anthesis of the genotypes Feltrin Vicenza Amarelo Baixo, UEL 2, Isla Macarrão Baixo, and Feltrin Macarrão Napoli is anticipated in the conventional production system. The genotype UEL 2 shows higher precocity in anthesis within the conventional system. The genotypes Isla Manteiga Baixo and UEL 1 produce more pods per plant in the conventional system. In the organic system, the genotype Feltrin Macarrão Napoli produces double the number of pods per plant compared with Isla Manteiga Baixo. The organic system leads to greater plant height and average mass, length, and diameter of pods in relation to the conventional system. The commercial pod yield of bushing snap bean is not altered by differences in the production system or genotype.

    2010-07-01

    The patent-pending system comprises a novel biohydrogen reactor with a gravity settler for decoupling of SRT from HRT. Two biohydrogenators were operated for 220 days at 37 C, hydraulic retention time 8 h and solids retention time ranged from 1.4 to 2 days under four different glucose concentrations of 2, 8, 16, 32, 48 and 64 g/L, corresponding to organic loading rates of 6.5-206 kg COD/m{sup 3}-d, and started up using anaerobically-digested sludge from the St. Marys wastewater treatment plant (St.Mary, Ontario, Canada) as the seed. The system steadily produced hydrogen with no methane. A maximum hydrogen yield of 3.1 mol H{sub 2} /mol glucose was achieved in the system for all the organic loading rates with an average of 2.8mol H{sub 2} /mol glucose. Acetate and butyrate were the main effluent liquid products at concentrations ranging from 640-7400 mg/L and 400-4600 mg/l, respectively, with no lactate detection. Microbial community analysis using denaturing gradient gel electrophoresis (DGGE) confirmed the absence of lactate producing bacteria Lactobacillus fermentum and other non-hydrogen producing species, and the predominance of various Clostridium species. Biomass concentrations in the biohydrogenators were steady, during the runs, varying form 1500 mg/L at the OLR of 6.5 kg COD/m{sup 3}-d to 14000 mg/L at the 104 kg COD/m{sup 3}-d, thus emphasizing the potential of this novel system for sustained stable hydrogen production and prevention of biomass washout.

    Organic aerosol (OA, i.e., the organic fraction of particles) accounts for 10–90% of the fine aerosol mass globally and is a key determinant of aerosol radiative forcing. But atmospheric OA is poorly characterized and its life cycle insufficiently represented in models. As a result, current models are unable to simulate OA concentrations and properties accurately. This deficiency represents a large source of uncertainty in quantification of aerosol effects and prediction of future climate change. Evaluation and development of aerosol models require data products generated from field observations. Real-time, quantitative data acquired with aerosol mass spectrometers (AMS) (Canagaratna et al. 2007) are critical to this need. The AMS determines size-resolved concentrations of non-refractory (NR) species in submicrometer particles (PM1) with fast time resolution suitable for both ground-based and aircraft deployments. The high-resolution AMS (HR-AMS), which is equipped with a high mass resolution time-of-flight mass spectrometer, can be used to determine the elemental composition and oxidation degrees of OA (DeCarlo et al. 2006).

    Biogenic Volatile Organic Compounds (BVOC) are important precursors in photochemical O3 and secondary organic aerosol (SOA) formation. We conducted a series of laboratory experiments with OH-induced oxidation of monoterpenes to elucidate pathways and efficiencies of O3 and SOA formation. At high NOx conditions ([BVOC] / [NOx] monoterpene mixes emitted from different plant species we observed increasing ozone formation with increasing [NOX]. Between 2 and 3 O3-molecules were formed from 1 monoterpene when ozone formation was BVOC limited. Under such high NOX conditions, new particle formation was suppressed. Increasing [BVOC] / [NOX] ratios caused increasing efficiency of new particle formation indicating that peroxy radicals are the key intermediates in both, photochemical ozone- and new particle formation. The classical chemistry of peroxy radicals is well established (e.g. Master Chemical Mechanism). Peroxy radicals are produced by addition of molecular oxygen to the alkyl radical formed after OH attack at the BVOC. They either react with NO which leads to ozone formation or they react with other peroxy radicals and form chemically stable products (hydroperoxides, alkoholes and ketones). Much less knowledge exists on such reactions for Highly Oxidized Peroxy Radicals, (HOPR). Such HOPR were observed during ozonolysis of several volatiles and, in case of monoterpenes as precursors, they can contain more than 12 Oxygen atoms (Mentel et al., 2015). Although the OH-initiated formation of HOPR is yet not fully understood, their basic gas phase reactions seem to follow classical photochemical rules. In reactions with NO they can act as precursor for O3 and in reactions with other HOPR or with classical less oxidized peroxy radicals they can form highly oxidized stable products and alkoxy radicals. In addition, HOPR-HOPR reactions lead to the formation of dimers that, in case of monoterpenes as reactants, consist of a skeleton with 20 carbon atoms. These dimers seem to

    Peste des petits ruminants (PPR) is a viral disease which primarily affects small ruminants, causing significant economic losses for the livestock industry in developing countries. It is endemic in Saharan and sub-Saharan Africa, the Middle East and the Indian sub-continent. The primary hosts for peste des petits ruminants virus (PPRV) are goats and sheep; however recent models studying the pathology, disease progression and viremia of PPRV have focused primarily on goat models. This study evaluates the tissue tropism and pathogenesis of PPR following experimental infection of sheep and goats using a quantitative time-course study. Upon infection with a virulent strain of PPRV, both sheep and goats developed clinical signs and lesions typical of PPR, although sheep displayed milder clinical disease compared to goats. Tissue tropism of PPRV was evaluated by real-time RT-PCR and immunohistochemistry. Lymph nodes, lymphoid tissue and digestive tract organs were the predominant sites of virus replication. The results presented in this study provide models for the comparative evaluation of PPRV pathogenesis and tissue tropism in both sheep and goats. These models are suitable for the establishment of experimental parameters necessary for the evaluation of vaccines, as well as further studies into PPRV-host interactions. PMID:24498032

    In this study, the V3 and V4 regions of the 16S rRNA gene from metagenomic DNA were sequenced to identify differences in microbial diversity in raw milk of Saanen and Guanzhong goats from the Guanzhong area of China. The results showed that Proteobacteria was the predominant phylum, accounting for 71.31% of all phyla identified in milk from the 2 breeds, and Enterobacter was the predominant genus (24.69%) within the microbial community. Microbial alpha diversity from Saanen goat milk was significantly higher than that of Guanzhong goat milk based on bioinformatic analysis of indices of Chao1, Shannon, Simpson, observed species, and the abundance-based coverage estimator. Functional genes and their likely metabolic pathways were predicted, which demonstrated that the functional genes present in the bacteria in goat milk were enriched in pathways for amino acid metabolism and carbohydrate metabolism, which represented 11.93 and 11.23% of functional genes, respectively. Physicochemical properties such as pH, protein, fat, and AA levels were also determined and correlations made with microbial diversity. We detected a significant difference in the content of lactose and 6 AA, which were higher in Saanen milk than in Guanzhong milk, and positively correlated with microbial carbohydrate metabolism and AA metabolism. Lactococcus, Lactobacillus, Bifidobacterium, Enterococcus, and Streptococcus, which are lactose-utilizing genera, were more abundant in Saanen milk than in Guanzhong milk. Higher levels of lactose in Saanen goat milk may explain its greater microbial diversity. We also demonstrated that most of the AA metabolism-related bacterial genera (e.g., Massilia, Bacteroides, Lysobacter) were enriched in Saanen goat milk. In this research, both probiotic and pathogenic bacteria were identified in goat milk, which provided the microbial information necessary to direct the utilization of beneficial microbial resources and prevent the development of harmful organisms in
