Full Text Available In the year 2007 there was price jump at world milk market. In the middle of the year 2008 the market was temporarily stabilized, because European Commission introduced Common Agricultural Policy modernization suggestion to the members of the European Parliament as the answer to an increasing food demand. The main elements of this suggestion were to abolish obligation to keep some agricultural areas set aside, milk quota removal, and abolition of subvention rate - production quantity link. When East and Central European countries entered in the European Union, they faced agricultural tax and milk price decrease. Today in new member states, the protection taxes are lower then before entering the Union (exceptions are Poland and Romania. The production costs in new member states are higher then in the Union, so there is higher market pressure at milk producers to increase their capacity (Livestock unit, to increase capacity utilization (milk per animal, and to produce at lower cost price. One part of smaller producers could not react to this pressure, so they decided to leave the dairy business. The consequence is decreased export of milk and dairy products in the new member states. Today milk market production in Croatia is around 650 million liters. In the production, there are around 32 thousand producers with 177 thousand of dairy cows. In the last 5 years of Croatian dairy, there was important shift in the production and redemption. Help to dairy sector through annual high investments as state subsidies and credit loans, and dairy industry subsidies at basic price, made redemption increase of more then 150 million liters, but also milk producer’s decrease. To stay at present production and redemption level, the only one that counts as Quota I, with around 90 % standard milk, there is a need to increase standard milk for 119 million liters. This increase in production quality, in the negotiation period and just after planned Croatian

Peri-urban dairy production systems in developing countries: Characteristics, potential and opportunities for improvement

International Nuclear Information System (INIS)

Devendra, C.

Full text: Peri-urban dairy production systems in developing countries are discussed with reference to type of systems, their characteristics, potential, and opportunities for improvement. Three types of dairy systems are identified and described: smallholder systems, smallholder co-perative dairy production systems, and intensive dairy production systems. The first two systems are by far the most important, and are associated with increasing intensification. Buffaloes are especially important in South Asia, but elsewhere dairy production mainly involves Holstein-Friesian cross-bred cattle. Dairy goats are important in some countries, but are generally neglected in development programmes. The expansion and intensification of peri-urban dairy production is fuelled by increased demand for milk with associated problems of milk handling and distribution, hygiene and environmental pollution. The major constraints to production are inter alia, choice of species, breeds and availability of animals; feed resources and improved feeding systems; improved breeding, reproduction, and animal health care; management of animal manure, and organised marketing, and market outlets. These constraints provide major opportunities and challenges for research and development to increase dairy production, efficient management of natural resources, and improved livelihoods of poor farmers. Specific areas for research are identified, as also the need of a holistic focus involving interdisciplinary research and integrated natural resource management, in a shared partnership between farmers and scientists that can demonstrate increased productivity and sustainable production systems. Suggestions for performance indicators for such systems are indicated. (author)

Full Text Available Tanzania is primarily an agro-based economy, characterized by subsistence agricultural production that employs more than 80% of the population and contributes up to 45% of the GDP (2005. This country is endowed with a cattle population of 21.3 M, composed mainly of indigenous Zebu breeds and about 680 000 improved dairy animals. About 70% of the milk produced comes from the traditional sector (indigenous cattle kept in rural areas, while the remaining 30% comes from improved cattle, mainly kept by smallholder producers. In Northern Tanzania and particularly in Hai district of Kilimanjaro Region, some dairy farmers organize themselves into small producer groups for the purpose of milk collecting, marketing and general promotion of the dairy sector in their community. Nronga Women Dairy Cooperative Society (NWDCS Limited is one of such organizations dedicated to improve the well-being of the Nronga village community through promoting small-scale dairy farming and its flow-on benefits. Milk flows out of the village, and services for investment and dairy production flow into the village, ensuring a sustainable financial circulation necessary for poverty reduction, rural development and better life for the rural community. In 2001 NWDCS introduced a school milk feeding program that has attracted Australian donors since 2005. Guided by Global Development Group, a multi-faceted project, integrating micro-enterprises, business, education and child health/nutrition, was proposed and initiated by building a dairy plant in Hai District headquarters, the Boma plant. In March 2013, the Australian High Commission to East Africa approved Direct Aid Program funding of AUD 30 000 towards the NWDCS - Biogas Pilot Project in Tanzania, which included the renovation of zero-grazing cow shade units, the construction of 6-m3 biodigester plants on each farm, and encouragement of the use of bioslurry for pasture production and home gardens.

Wicked problems: a value chain approach from Vietnam's dairy product.

2013-12-01

In the past few years, dairy industry has become one of the fastest growing sectors in the packaged food industry of Vietnam. However, the value-added creation among different activities in the value chain of Vietnam dairy sector is distributed unequally. In the production activities, the dairy farmers gain low value-added rate due to high input cost. Whereas the processing activities, which managed by big companies, generates high profitability and Vietnamese consumers seem to have few choices due to the lack of dairy companies in the market. These wicked problems caused an unsustainable development to the dairy value chain of Vietnam. This paper, therefore, will map and analyze the value chain of the dairy industry in Vietnam. It will also assess the value created in each activity in order to imply solutions for a sustainable development of Vietnam's dairy industry. M10, M11.

Aline dos Santos Neutzling

2017-12-01

Full Text Available Milk production is a socio-economically relevant activity for many small-scale family farms in southern Brazil. The objective of this study was to analyse their production and marketing strategies. A questionnaire was administered to 199 farm households in Rio Grande do Sul State to collect information on farm assets and activities, and particularly on the contribution of milk sale to farm income. Through categorical principal component analysis and two-step clustering, farmers were classified into three types: farmers selling only milk (M; farmers selling cash crops and milk (CM; farmers selling cash crops and surplus milk (Cm. Cattle herd (heads and size of pasture land were larger on M farms (114 ±71.9; 51 ±49.4 ha than on CM (31 ±13.4; 9 ±8.9 ha and Cm (12 ±7.5; 5 ±8.1 ha farms. Livestock husbandry contributed 71, 59 and 16 % to family income on M, CM and Cm farms, respectively. Daily milk production of the individual cow depended on the area cultivated with fodder maize (ha per cow; p ≤ 0.001, on sale of milk to cooperatives or to private companies (p ≤ 0.01, on summer pasture area (ha per cow; p = 0.001 and on daily amount of concentrates offered (kg per cow; p ≤ 0.01. These results indicate that the area available for fodder cultivation is a key factor for milk production on small-scale dairy farms in southern Brazil, while concentrate feeding plays a less important role even for highly market-oriented farms. This must be accounted for when exploring options for strengthening the regional small-scale milk production, in which dairy cooperatives do play an important role.

The global dairy industry is composed of a multitude of countries with unique production practices and consumer markets. The global average number of cows per farm is about 1-2 cows; however, as a farm business model transitions from sustenance to market production, the average herd size, and subsequent labor force increases. Dairy production is unique as an agricultural commodity because milk is produced daily, for 365 days per year. With the introduction of new technology such as the milking parlor, the global industry trend is one of increasing farm sizes. The farm sizes are the largest in the United States; however, the European Union produces the most milk compared with other global producers. Dairy production is essential for economic development and sustainable communities in rural areas. However, the required capital investment and availability of local markets and labor are continued challenges. Due to farm expansion, international producers are faced with new challenges related to assuring food safety and a safe working environment for their workforce. These challenges exist in addition to the cultural and language barriers related to an increasing dependence on immigrant labor in many regions of the world. Continued success of the global dairy industry is vital. Therefore, research should continue to address the identification of occupational risk factors associated with injuries and illnesses, as well as develop cost-effective interventions and practices that lead to the minimization or elimination of these injuries and illnesses on a global scale, among our valuable population of dairy producers and workers.

Full Text Available This paper aims to investigate factors influencing the purchasing behavior of Palestinian customers towards domestic and imported dairy products (Israeli and foreign. The secondary data were obtained from the competent authorities. On the other hand, primary data were gathered by utilizing personal interviews and questionnaires. 450 questionnaires were distributed to all governorates of the West Bank. It has been concluded from statistical results that middle-income households concern mainly about quality, image and product validity period. In contrast, low-income households consider mainly product price. The consumer was satisfied with Israeli products that meet his needs. On the other hand, local consumer highly considered price and personal knowledge when purchasing local dairy products. Advertising negatively affected the consumer purchasing behavior of Israeli and foreign dairy products, in contrast it positively affected his behavior when purchasing local dairy products. Period of validity was the most influential factor on the purchasing decision for domestic and imported dairy products. It has been found that consumer expenditures on Israeli dairy products were the highest followed by local and foreign products. Recommendations are as follows: i producers should develop products that could meet the needs and desires of consumers, ii draw effective marketing policies, depending on technologists specialized in dairy industry, iii take into account consumer awareness when developing advertising strategy, and iv quality control should be adjusted in accordance with product specifications and standards.

Much has been published on the nutritional and health benefits of fermented dairy products, especially those containing probiotic microorganisms. However, consumers may not be familiar with the term "fermented dairy products," and therefore may not take full advantage of them. University students' knowledge and consumption patterns of fermented dairy products were assessed. University students (n=223) completed a survey consisting of a section on demographics and another on knowledge and consumption patterns. The majority of respondents (62%) were not familiar with the term "fermented dairy products." Most respondents consumed yogourt a few times a week (40%) or a few times a month (30%). Almost all respondents (92%) were unable to identify the difference between regular and probiotic yogourt. Most respondents (93%) had not heard of acidophilus milk, but the majority (65%) would be willing to try it. Most respondents were unsure whether sour cream (65%), yogourt beverages (74%), and cheddar cheese (61%) were fermented dairy products. Sixty percent of respondents never consumed yogourt drinks. Education is needed about fermented dairy products, especially probiotics, and their nutritional and health benefits. Such education may increase their acceptability and consumption.

The answer to the question posed in the title is arguably, yes. U.S. firms appear to be well positioned to profitably expand exports of highly differentiated dairy products and selected dairy ingredients, especially dried whey products. However, U.S. bulk cheese, butter and nonfat dry milk (NFDM) are, for the most part, priced out of foreign markets by U.S. border protection and the dairy price support program. If, as claimed by a former Nestle CEO, the U.S. dairy-food market is "flat and fie...

Dairy products, yogurts, and bone health.

Rizzoli, René

2014-05-01

Fracture risk is determined by bone mass, geometry, and microstructure, which result from peak bone mass (the amount attained at the end of pubertal growth) and from the amount of bone lost subsequently. Nutritional intakes are an important environmental factor that influence both bone mass accumulation during childhood and adolescence and bone loss that occurs in later life. Bone growth is influenced by dietary intake, particularly of calcium and protein. Adequate dietary calcium and protein are essential to achieve optimal peak bone mass during skeletal growth and to prevent bone loss in the elderly. Dairy products are rich in nutrients that are essential for good bone health, including calcium, protein, vitamin D, potassium, phosphorus, and other micronutrients and macronutrients. Studies supporting the beneficial effects of milk or dairy products on bone health show a significant inverse association between dairy food intake and bone turnover markers and a positive association with bone mineral content. Fortified dairy products induce more favorable changes in biochemical indexes of bone metabolism than does calcium supplementation alone. The associations between the consumption of dairy products and the risk of hip fracture are less well established, although yogurt intake shows a weakly positive protective trend for hip fracture. By consuming 3 servings of dairy products per day, the recommended daily intakes of nutrients essential for good bone health may be readily achieved. Dairy products could therefore improve bone health and reduce the risk of fractures in later life.

Full Text Available Buffalo husbandry is an important source of income for a number of small-scale producers in Romania that is why an assessment of its products quality is much needed for improvement and evaluation of their vulnerability to international competition. In order to ascertain possible developments in the buffalo dairy sector and to broadly identify areas of intervention that favor small-scale dairy producers, the study examined the potential to improve buffalo milk production by evaluating its authenticity and hygienic quality. The methods used involved the molecular testing (PCR-technique for identifying cow, sheep or goat DNA in the dairy products samples collected from the small-scale producers market. The hygienic quality of these samples was determined through classical microbiology methods, highly developed techniques (Trek System and PCR for bacterial species confirmation. The results showed that a high percent (65%, from the products found were adulterated with other species milk, mostly cow milk. The most commonly falsified buffalo dairy products were the cheese and the traditional product telemea. The prevalence of the bacterial species identified belonged to Listeria innocua and Listeria welshmeri. The conclusion of this study is the need of a durable development system in this particular dairy chain to improve and assure the authenticity and quality of the small-scale producers products and their reliability for the consumers.

Non-Dairy Probiotic Foods

Full Text Available Probiotic products available in the markets today, are usually in the form of fermented milk products. Dairy consumption have been limited by lactose intolerance and the cholesterol content in dairy products. Besides, traditions and economic reasons that limit the use of dairy fermented products in some developing countries promote the idea of using of alternative raw materials as vehicles for the probiotic agents. For these reasons meat products, cereals, legumes, fruits and vegetables may be potential substrates, where the healthy probiotic bacteria will make their mark, amongst consumers. To develop of these products is a key research priority for food design and a challenge for both industry and science sectors. In this study, information’s were given about non-dairy probiotic foods and highlighting the researches done in this field.

Full Text Available Establishment of dairy cattle development region needs to be conducted in accordance with the national dairy industry development plan. Dairy cattle regions have been designed and equipped with infrastructure supplies, supporting facilities, technologies, finance, processing, marketing, institutional and human resources. Dairy cooperative is one of the marketing channels of milk and milk products which have strategic roles to support the national dairy industry. Collaborations between dairy cooperatives and smallholder farmers within a district region have to be done based on agricultural ecosystems, agribusiness system, integrated farming and participatory approach. This may improve dairy cooperatives as an independent and competitive institution. Strengthening dairy cooperatives in national region dairy cattle was carried out through institutional inventory and dairy cooperatives performance; requirement of capital access, market and networks as well as education and managerial training; certification and accreditation feasibility analysis and information and technology utilization. Establishment of emerging dairy cooperatives towards small and micro enterprises is carried out by directing them to establish cooperatives which have legal certainty and business development opportunities. The impact of strengthening dairy cooperative may support dairy cattle development through increase population and milk production. Sustainable dairy cattle development needs to be supported by regional and national government policies.

Full Text Available This study was specifically conducted in the four districts of Punjab province of Pakistan. The principal objective was to identify major explanatory variables that might influence dairy farmers’ market participation decisions regarding the selection of traditional and modern channels of milk marketing. Data was collected from field survey and the sample size comprised of 320 dairy farmers, randomly selected from study area. Multinomial logit model was used an econometric tool to estimate the impacts of fourteen independent variables on the dependent variable (selection of milk marketing channel. Model results showed that eight factors like gender, old aged farmers, long distance between dairy farm and urban market, easy milk selling at door step, advance cash payment, lack of quality inspection, strong social relationship with milk collectors, and better milk price were important predictors influencing milk producers to choose traditional channels for the sale of their milk produce. Impacts of these variables were significant at 5% of significance level except long distance which was significant at 1%. Conversely to this, fourfactors such as high education level of dairy farmers, large herd size, provision of extension services, and purchase of evening milk were motivating dairy farmers to sell milk through modern channels. Traditional milk channels were preferred by majority of milk producers but these channels were lacking in delivering the quality milk to consumers. Policy implication for sustainable milk marketing might be the provision of dairy advisory services, advance payment framework, improving logistic infrastructure, and enforcement of milk quality inspection could ensure milk safety along sustainable milk supply.

Greenhouse gas emissions in milk and dairy product chains: Improving the carbon footprint of dairy products

Energy Technology Data Exchange (ETDEWEB)

Flysjoe, A.M.

2012-11-01

The present PhD project has focused on some of the most critical methodological aspects influencing GHG emission estimates of milk and dairy products and how the methodology can be improved. In addition, the Carbon Footprint (CF) for different types of dairy products has been analysed. Based on these results, mitigation options have been identified along the entire dairy value chain. The key methodological challenges analysed in the present study are: estimation of CH{sub 4} and N{sub 2}O emissions, assessment of CO{sub 2} emissions from land use change (LUC), co-product handling, and definition of the functional unit. Estimates of the biogenic emissions CH{sub 4} and N{sub 2}O are associated with large uncertainties due to the complexity and natural variation in biological processes. Accounting for these variations resulted in a {+-}30-50% variation in the CF for milk in Sweden and New Zealand (excluding emissions from LUC). The inclusion of emissions from LUC can drastically affect the CF of dairy products, and different models can even provide contradictory results. Thus, it is suggested that emissions associated with LUC are reported separately and that underlying assumptions are clearly explained. Accounting for the by-product beef is decisive for the CF of milk, and when designing future strategies for the dairy sector, milk and meat production needs to be addressed in an integrated approach. It is shown that an increase in milk yield per cow does not necessarily result in a lower CF of milk, when taking into account the alternative production of the by-product beef. This demonstrates that it is important to investigate interactions between different product chains, i.e. to apply system thinking. The CF of dairy products from Arla Foods analysed in the present study range from: 1.2-5.5 kg CO{sub 2}e per kg fresh dairy products, 7.3-10.9 kg CO{sub 2}e per kg butter and butter blends, 4.5-9.9 kg CO{sub 2}e per kg cheese, and 1.0-17.4 kg CO{sub 2}e per kg milk

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

Full Text Available Buffalo husbandry is an important source of income for a number of small-scale producers in Romania that is why an assessment of its� product�s quality is much needed for improvement and evaluation of their vulnerability to international competition. In order to ascertain possible developments in the buffalo dairy sector and to broadly identify areas of intervention that favor small-scale dairy producers, the study examined the potential to improve buffalo milk production by evaluating its authenticity and hygienic quality. The methods used involved the molecular testing (PCR-technique for identifying cow, sheep or goat DNA in the dairy products� samples collected from the small-scale producers market. The hygienic quality of these samples was determined through classical microbiology methods, highly developed techniques (Trek System and PCR for bacterial species confirmation. The results showed that a high percent (65%, from the products found were adulterated with other species milk, mostly cow milk. The most commonly falsified buffalo dairy products were the cheese and the traditional product �telemea�. The prevalence of the bacterial species identified belonged to Listeria innocua and Listeria welshmeri. The conclusion of this study is the need of a durable development system in this particular dairy chain to improve and assure the authenticity and quality of the small-scale producers� products and their reliability for the consumers.

Dairy products and plasma cholesterol levels

Directory of Open Access Journals (Sweden)

Lena Ohlsson

Full Text Available Cholesterol synthesized in the body or ingested is an essential lipid component for human survival from our earliest life. Newborns ingest about 3–4 times the amount per body weight through mother's milk compared to the dietary intake of adults. A birth level of 1.7 mmol/L plasma total cholesterol will increase to 4–4.5 mmol/L during the nursing period and continue to increase from adulthood around 40% throughout life. Coronary artery disease and other metabolic disorders are strongly associated with low-density lipoprotein (LDL and high-density lipoprotein (HDL cholesterol as well as triacylglycerol concentration. Milk fat contains a broad range of fatty acids and some have a negative impact on the cholesterol rich lipoproteins. The saturated fatty acids (SFAs, such as palmitic acid (C16:0, myristic acid (C14:0, and lauric acid (C12:0, increase total plasma cholesterol, especially LDL, and constitute 11.3 g/L of bovine milk, which is 44.8% of total fatty acid in milk fat. Replacement of dairy SFA and trans-fatty acids with polyunsaturated fatty acids decreases plasma cholesterol, especially LDL cholesterol, and is associated with a reduced risk of cardiovascular disease. Available data shows different effects on lipoproteins for different dairy products and there is uncertainty as to the impact a reasonable intake amount of dairy items has on cardiovascular risk. The aim of this review is to elucidate the effect of milk components and dairy products on total cholesterol, LDL, HDL, and the LDL/HDL quotients. Based on eight recent randomized controlled trials of parallel or cross-over design and recent reviews it can be concluded that replacement of saturated fat mainly (but not exclusively derived from high-fat dairy products with low-fat dairy products lowers LDL/HDL cholesterol and total/HDL cholesterol ratios. Whey, dairy fractions enriched in polar lipids, and techniques such as fermentation, or fortification of cows feeding can be used

Allergens in food are a great health risk, because of the ratio of severity of problems compared to small amounts of ingested allergen. Since 2014, Serbian producers and importers of food have been obliged to declare allergens from the list of Codex Alimentarius on the product packaging. Surveillance of different meat, diary, and cereal product took place in 2016, with aim of checking if the Serbian regulatory requirements for labelling of allergens in food are being fulfilled. Out of 68 different meat products, 20 were not labelled for allergens. Thirty-six labels of various dairy products were examined revealing that allergen information was included on 27 of them. Only one of eight examined cereal products did not have allergen labelling.

Impacts of the Doha Round framework agreements on dairy policies.

Suzuki, N; Kaiser, H M

2005-05-01

Dairy is highly regulated in many countries for several reasons. Perishability, seasonal imbalances, and inelastic supply and demand for milk can cause inherent market instability. Milk buyers typically have had more market power than dairy farmers. Comparative production advantages in some countries have led to regulations and policies to protect local dairy farmers by maintaining domestic prices higher than world prices. A worldwide consensus on reduction of border measures for protecting dairy products is unlikely, and dairy will probably be an exception in ongoing World Trade Organization (WTO) negotiations. Under the Doha Round framework agreements, countries may name some products such as dairy as "sensitive," thereby excluding them from further reforms. However, new Doha Round framework agreements depart from the current WTO rule and call for product-specific spending caps. Such caps will greatly affect the dairy sector because dairy accounts for much of the aggregate measure of support (AMS) in several countries, including the United States and Canada. Also, the amounts of dairy AMS in several countries may be recalculated relative to an international reference price. In addition, all export subsidies are targeted for elimination in the Doha Round, including export credit programs and state trading enterprises, which will limit options for disposing of surplus dairy products in foreign markets. Currently, with higher domestic prices, measures for cutting or disposing of surpluses have been used in many countries. Supply control, which is not regulated by WTO rules, remains as an option. Although explicit export subsidies are restricted by WTO rules, many countries use esoteric measures to promote dairy exports. If countries agree to eliminate "consumer financed" export subsidies using a theoretical definition and measurements proposed herein as Export Subsidy Equivalents (ESE), dairy exports in many countries may be affected. Although domestic supports and

Full Text Available Milk and dairy products constitute an important source of energy and nutrients for humans. Food preferences may significantly influence the actual consumption (and thus nutrition of people at the population level. The objective of the present large-scale survey was to specify current preferences for milk and dairy products with regard to age and sex. The study was conducted across the Moravia region, Czech Republic, on a sample of 451 individuals divided into 4 age groups: children, adolescents, young adults, and elderly people. A graphic scale questionnaire was administered, with respondents rating their degree of preference for each food item by drawing a mark on a 35 mm line. Out of the 115 items in the questionnaire, 11 items represented dairy products. Data was analysed by means of a general linear model using IBM SPSS Statistics software. Preference for milk was lower in the elderly group than the other groups (P P < 0.01. The overall preference for dairy products (21.6 was lower than the average preference for all foods on the list (22.5. The cross-sectional study revealed intergenerational differences in preferences for specific dairy products, which were most marked in case of cream, processed cheese, blue cheese, and buttermilk. The knowledge of these differences might help promote more focused action at the community level directed at increasing the overall consumption of dairy products in the population.

MYCOBACTERIUM AVIUM SUSP. PARATUBERCULOSIS IN DAIRY PRODUCTION

Full Text Available Mycobacterium avium subsp. paratuberculosis (MAP is the etiologic agent of paratuberculosis. The disease affects cows and other ruminants and causes high economic losses, mainly for dairy production. MAP may also have a role in the development of Crohn’s disease in humans. Infected animals shed viable MAP with milk and faeces and humans may assume MAP via the consumption of contaminated milk and dairy products. Current methods of milk pasteurization are not sufficient to kill all MAP cells present in milk and MAP has been found in raw or pasteurized milk and isolated from cheese. The aim of this paper is to review the current knowledge about MAP in dairy production. We analyzed studies on milk contamination, effect of pasteurization and methods for identification of MAP that can be applied to dairy products.

Full Text Available An intensive development in Indonesian dairy industry has expanded over two decades. During this period, the structure of the national dairy industry has progressed completely. The capacity of the national fresh milk production, however, has been able to supply only 35% of domestic milk demand. The milk domestic demand is predicted to be continous due to the increases in the national population and their welfare. Raising temperate dairy breed (Holstein-Friesian under tropical climate has resulted many deteriorates in productivity. More inferiority has been found under a semi-intensive management at small dairy farms. The existence of various changes in the global trade regulation for agriculture commodities has been a considerable factor directly affecting the future development of the national dairy industry. Increasing efficiency of various determinant components of the national dairy industry is required to produce domestic fresh milk in a good quality at a competitive price. This paper is dealing with the status of various determined factors especially for dairy livestock components to improve the future national dairy industry prospectively, involving for the national dairy cattle population, domestic milk yield, productivity of dairy cattle, breeding system and supporting reproduction technology. More over, other essential factors providing for dairy institution as well as distribution and marketing domestic milk production are also described.

The number of dairy productivity performance within the normal. Shortages as well as high cost of feed, occurrence of disease, scarce information about feeding and high medicament cost were the main constraints which might have contributed considerably to delayed age at first service, late age at first calving, long calving interval, short lactation length and low milk production. Therefore, strategies designed to solve the existing problem should be important by involving all stakeholders in the formulation and implementation of improvement strategiesor dairy development policy was being implemented and necessary respect to environmental factors affecting agricultural activities such as a constraint on land use and access to water resources.

The perceived value of dairy product traceability in modern society: An exploratory study.

Charlebois, Sylvain; Haratifar, Sanaz

2015-05-01

The current study assessed the perceived value of food traceability in modern society by young consumers. After experiencing numerous recalls and food safety-related incidences, consumers are increasingly aware of the tools available to mitigate risks. Food traceability has been associated with food safety procedures for many years, but recent high-profile cases of food fraud around the world have given traceability a different strategic purpose. Focusing solely on dairy products, our survey results offer a glimpse of consumer perceptions of traceability as a means to preserve food integrity and authenticity. This study explored the various influences that market-oriented traceability has had on dairy consumers. For example, results show that if the dairy sector could guarantee that their product is in fact organic, 53.8% of respondents who often purchase organic milk would consider always purchasing traceable organic milk. This research produced a quantitative set of information related to the perceived value of food traceability, which could be useful for the creation and development of improved guidelines and better education for consumers. We discuss limitations and suggest areas for new research. Copyright © 2015 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

A 100-Year Review: The production of fluid (market) milk.

Science.gov (United States)

Barbano, David M

2017-12-01

During the first 100 years of the Journal of Dairy Science, dairy foods and dairy production dairy scientists have partnered to publish new data and research results that have fostered the development of new knowledge. This knowledge has been the underpinning of both the commercial development of the fluid milk processing industry and regulations and marketing policies for the benefit of dairy farmers, processors, and consumers. During the first 50 years, most of the focus was on producing and delivering high-quality raw milk to factories and improving the shelf life of pasteurized fluid milk. During the second 50 years, raw milk quality was further improved through the use of milk quality payment incentives. Due to changing demographics and lifestyle, whole fluid milk consumption declined and processing technologies were developed to increase the range of fluid milk products (skim and low-fat milks, flavored milks, lactose-reduced milk, long-shelf-life milks, and milks with higher protein and calcium contents) offered to the consumer. In addition, technology to produce specialty high-protein sports beverages was developed, which expanded the milk-based beverage offerings to the consumer.

been involved from then on in research, particularly in mastitis surveys, has trained stakeholders and has provided analytical support to stations of the Animal Production Division. Over the years, DCD expanded its services to cover the various stake­holders of the dairy sector. From 1986 until closure of the three Government stations, DCD monitored, weekly, the morning and afternoon milk quality of these stations. DCD also monitored the quality of dairy products manufactured locally by performing chemical and microbiological analyses at the request of major local food manufacturers, importers and micro-entrepreneurs. Technical assistance was provided to other governmental and non-governmental organizations such as the Mauritius Standards Bureau, the Food and Agricultural Research and Extension Institute, the Mauritius Livestock Marketing Cooperative Federation, and the Ministry of Health and Quality of Life. Figure 1 shows the change in the number of samples submitted at DCD from 1999 to 2014. Years 2004 to 2007 were marked by investments in staff training, purchase of new equipment, and culminated with the transfer to new premises. Figure 2 shows the trend (2004–2007 in the monthly average fat content in raw milk submitted by the Agricultural Marketing Board. In 2006, DCD moved to its new location and added to its usual activities at the Food Technology Laboratory new responsibilities in the fields of microbiological testing, product development, and activities pertaining to the operation of the Codex Contact Point. Following integration of the Food Hygiene Laboratory of the Veterinary Services under the Food Technology Laboratory complex in 2006, the scope of activities has broadened. The different units have been fully equipped with state-of-the-art equipment and the personnel have been regularly trained to meet the growing requirements of the local agro-business sec­tor.

2011-04-01

Full Text Available Clean milk production is one important aspect in enhancing the quality of milk. It is important to know farmers' perception about it. With this view, present study was undertaken with the objective of understanding perception of dairy farmers about clean milk production. The study was conducted in six villages of Gadag district of Karnataka state. A total of 180 respondents were interviewed. Perceptions of the farmers regarding family manpower involved in dairy farming, personnel involved in milking, dairy income, intention to produce clean milk, price dependence for following clean milk production, reasons for following cleanliness measures in milk production, sale price received for milk and satisfaction for the price they received for milk were studied. Most of the dairy farmers expressed their willingness to follow clean milk production measures. Further, most of them were ready to follow such measures even if they were not paid more price for milk. Farmers practiced clean milk production measures mainly to follow regulations at the dairy co-operative society followed by to avoid spoilage of milk. Dairy farmers largely neglected impact of cleanliness on animals' udder and health, about milk contamination causing health hazards. Milking was mainly a domain of women. For over 80 % farmers, dairy farming provided a moderate income as portion of their total family income. Majority of the producers were not satisfied with price they were getting for milk. Hence, the study recommends, requisite facilities and guidelines from the agencies concerned are needed to be provided to the dairy farmers to adopt clean milk production practices. Proper education to the farmers regarding importance of clean milk production from health, marketing and animal health point of views needs to be given. There is need to give more importance to women in dairy farmers' trainings. The study also suggests offering satisfactory price for milk to hasten the process of

Consumption of dairy products in the UAE: A comparison of nationals and expatriates

Kamaleldin Ali Bashir

2011-06-01

Full Text Available The variables: age, income, education, number of children, and a dichotomous dummy variable for nationality were used to explain the consumption behavior of dairy products: fresh milk, butter, cheese, yoghurt, powdered milk, condensed milk, cream, and ice cream in the urban centers of Al-ain, Dubai, and Abu Dhabi. Results suggest different determinants for consumption behaviors of nationals and expatriates as well as different determinants along the income range of the sample. Estimates for the expenditure elasticity were relatively higher for lower income groups when unreported income is taken into consideration in interpreting the results. Differences in consumption behavior bear an important implication to marketing and promotion of dairy products: different strategies that incorporate the different consumption determinants are perhaps necessary for the different ethnic groups.

2002-01-01

Full Text Available This paper presents the evaluation of economic efficiency of dairyproduction on a family farm with 14 dairy cows in the breeding stock, and with average production from 3.206 to 3.407 lit. of milk annually. On the basis of survey data for three-year period from 1998 to 2000, economic indicators were calculated, as well as the cost price of milk, income and the revenue of total production and per production head. In the family farm with an average annual sale from 2.827 to 2.972 lit. of milk per head, total revenue has been realized from 44.884 to 47.695 kuna and the profit from 606 to 8.515 kuna. Revenues per production head were from 5.655 to 6.495 kuna and the profitfrom 177 to 726 kuna. The milk cost price in the analyzed period was 1.71, 1.66 and 1.69 kn. per lit, and the profit per liter of milk was 0.06, and 0.21 kn. Basic economic indicators point out on efficiency of dairy production for the investigated farm on the stated production level. The biggest influence on the dairy production efficiency on the farm, regarding the cost price structure, has been registered from the costs of fodder production, while the favorable parity of the cost price and producer-sale price of milk determines the increase in dairy production efficiency and income from dairy production in the analyzed period.

Market orientation of the Hungarian SMEs working in the meat processing and dairy industries

2016-12-01

Full Text Available We are looking for the answer as to what tendencies were indicative of the future development of required marketing activity of the SMEs in the article dealing with the marketing activity of the SMEs working in the food industry. The article is based on a nationwide survey among 200 SMEs working in the food processing industry. In this article, we focus on the SMEs working in the dairy and meat processing industries. The results of the nationwide research and some domestic references refer to that there is a latent demand of effective marketing activity among small and medium-sized enterprises. It manifests itself in specifying marketing-related fields to be improved in the future. The marketing itself is believed not to be an important field at the same time. This apparent opposition is the small enterprise marketing paradox in the background of which is the lack of knowledge about the marketing instruments. It can be stated that these small businesses collect mainly general market information and have no information about particular products. Therefore, the presence of marketing planning is really rare and where there is some kind of planning it is not connected to available funds and follow-up control. The marketing strategy can be characterized by products processed mainly at low or medium level. Therefore, market position is deffned by “lower price-good quality”. They mainly use the traditional distribution channels and their communication is accidental and has a low level.

The Spatial Patterns of Dairy Farming In Molise

Ievoli Corrado

2017-12-01

Full Text Available The greater market orientation of European dairy production, caused by the end of quota regime, is likely to have consequences on less favoured areas, where breeding of dairy cattle plays both a crucial socio-economic and environmental role. Within this new framework, endogenous factors determining spatial reorganisation of the sector are becoming of increasing relevance. Based on these considerations, this study analyses the impact of the three broader classes of location determinants suggested by economic theory - factor endowment, market potential, and spatial agglomeration externalities - on the spatial pattern of milk production in Molise, a rural region in the south of Italy. Milk production is measured in term of dairy cows per hectare. The truncated distribution of this variable and its high degree of spatial autocorrelation prompted us to apply a Spatial Autoregressive Tobit model. Estimation results reveal that all three categories have a positive effect on the location of milk production, even if the influence of factor endowment (intended as forage area, and market potential (measured in term of proximity of dairy companies is quite limited. On the contrary, the impact of spatial externalities (related variety on the regional localisation of milk production is strongly significant. These results cast some doubts on the current measures of intervention and might suggest a new policy framework both at firm and spatial level

Gammaspectroscopic measurements are taken as an example to describe the monitoring programme of the FRG for monitoring of milk and dairy products. A table shows the number of milk samples taken every year in the FRG in the general environment, and in the vicinity of nuclear installations, together with the radioactivity data obtained by gammaspectroscopy. Due to the decreasing radioactivity as a result of the nuclear weapons tests fallout, the number of samples taken in the general environment has been cut down to half over the period under review. The monitoring capacity set free by this decision has been used during this period for enhanced monitoring of milk and dairy products in regions where nuclear installations such as nuclear power plants have been operating. The nuclides of interest are Sr-90, Cs-137, J-131. (orig./DG) [de

A total of 200 samples of milk and dairy products as well as 120 samples of dairy handlers were randomly collected from different dairy farms and supermarkets in Dakahlia Governorate, Egypt. The conventional cultural and serotyping methods for detection of Salmonella in dairy products were applied and the results were compared with those obtained by molecular screening assay using (ttr sequence). The obtained results revealed that 21% of milk and dairy products (42/200) were positive for Salmonella species using enrichment culture-based PCR method, while 12% of different dairy samples (24/200) were found to be positive for Salmonella species by using the conventional culture methods. Two stool specimens out of 40 apparently healthy dairy handlers were positive by the PCR method. Serotyping of Salmonella isolates revealed that 58.3% (14/24) from different dairy products were contaminated with Salmonella Typhimurium. We conclude that the enrichment culture-based PCR assay has high sensitivity and specificity for detection of Salmonella species in dairy products and handlers. High incidence of Salmonella Typhimurium in the examined dairy samples highlights the important role played by milk and dairy products as a vehicle in disease prevalence. Great effort should be applied for reducing foodborne risk for consumers.

Vaughn, Alexandra R; Sivamani, Raja K

2015-07-01

Fermented dairy products, such as yogurt, have been proposed as a natural source of probiotics to promote intestinal health. Growing evidence shows that modulation of the gastrointestinal tract microbiota can modulate skin disease as well. This systematic review was conducted to examine the evidence for the use of ingested fermented dairy products to modulate skin health and function. We also sought to review the effects of the topical application of dairy products. The PubMed and Embase databases were systematically searched for clinical studies involving humans only that examined the relationship between fermented dairy products and skin health. A total of 312 articles were found and a total of 4 studies met inclusion criteria. Three studies evaluated the effects of ingestion, while one evaluated the effects of topical application. All studies noted improvement with the use of fermented dairy. Overall, there is early and limited evidence that fermented dairy products, used both topically and orally, may provide benefits for skin health. However, existing studies are limited and further studies will be important to better assess efficacy and the mechanisms involved.

Little is known about consumers' behavior especially their choice behavior toward purchasing and consuming dairy products in developing countries. Hence, the aim of the present work is understanding the factors that affect on consumers' choice behavior toward dairy products in Iran. The study applies the theory of consumption values, which includes the functional values (taste, price, health, and body weight), social value, emotional value, conditional value and epistemic value. The sample were 1420 people (men and women). The data was collected using face to face survey in summer and fall 2015. Chi-square, confirmatory factor analysis, and structural equation modelling is used to assess data collected. The results indicate that functional values, social value, emotional value and epistemic value have a positive impact on choosing dairy products and conditional value didn't have a positive impact. It was concluded that the main influential factors for consumers' choice behavior toward dairy products included consumers experience positive emotion (e.g. enjoyment, pleasure, comfort and feeling relaxed) and functional value-health. This study emphasized the proper pricing of dairy products by producers and sellers. Copyright © 2016 Elsevier Ltd. All rights reserved.

Microbiological Spoilage of Dairy Products

Science.gov (United States)

Ledenbach, Loralyn H.; Marshall, Robert T.

The wide array of available dairy foods challenges the microbiologist, engineer, and technologist to find the best ways to prevent the entry of microorganisms, destroy those that do get in along with their enzymes, and prevent the growth and activities of those that escape processing treatments. Troublesome spoilage microorganisms include aerobic psychrotrophic Gram-negative bacteria, yeasts, molds, heterofermentative lactobacilli, and spore-forming bacteria. Psychrotrophic bacteria can produce large amounts of extracellular hydrolytic enzymes, and the extent of recontamination of pasteurized fluid milk products with these bacteria is a major determinant of their shelf life. Fungal spoilage of dairy foods is manifested by the presence of a wide variety of metabolic by-products, causing off-odors and flavors, in addition to visible changes in color or texture.

Teo Vujčić

2005-01-01

Full Text Available Croatia today is in the economy transition process that also includes agriculture aiming to increase production and achieving competitive standard with international and European markets. Currently, domestic cow milk production ensures 80% of annual milk and dairy products requirements with the 20% import. In the period from 1990-1992, during the patriot war, 103000 cows and heifers were destroyed. Since then, Croatia started the gradual process of reorganization of the agricultural private sector including dairy business in order to increase production insensitivity.The agricultural structure of dairy segment is unsatisfactory with only 23.39% of farms holding four or more heifers. Households with 3 cows per farm dominate with average real estate of 0.10-3.0 acres.Changes in milk production (1990-2003 are reflected in the decrease of the number of breeding cattle – index 56.13%, and decrease of milk market producers from 65 000 to 65 151. Never the less, positive trends towards stabilization in milk production (2003 – 642 mil litres and annual milk intake increased from 342 mil litres in 1990 to 472 mil litres in 2003 (index 138.08% can be noticed. Changes in the structure of milk producers show certain positive movements as 23.39% of producers have 53.40% cows and respectively participation in milk production and buy off. Until 2008, with determined development conditions, cow milk production can increase for 42% and from 2703 litres to average of 4000 litres per dairy cow.

Céspedes, Mario; Cárdenas, Pamela; Staffolani, Martín; Ciappini, María C; Vinderola, Gabriel

2013-05-01

The increase in vegetarianism as dietary habit and the increased allergy episodes against dairy proteins fuel the demand for probiotics in nondairy products. Lactose intolerance and the cholesterol content of dairy products can also be considered two additional reasons why some consumers are looking for probiotics in other foods. We aimed at determining cell viability in nondairy drinks and resistance to simulated gastric digestion of commercial probiotic lactobacilli commonly used in dairy products. Lactobacillus casei LC-01 and L. casei BGP 93 were added to different commercial nondairy drinks and viability and resistance to simulated gastric digestion (pH 2.5, 90 min, 37 °C) were monitored along storage (5 and 20 °C). For both strains, at least one nondairy drink was found to offer cell counts around 7 log orders until the end of the storage period. Changes in resistance to simulated gastric digestion were observed as well. Commercial probiotic cultures of L. casei can be added to commercial fruit juices after a carefull selection of the product that warrants cell viability. The resistance to simulated gastric digestion is an easy-to-apply in vitro tool that may contribute to product characterization and may help in the choice of the food matrix when no changes in cell viability are observed along storage. Sensorial evaluation is mandatory before marketing since the product type and storage conditions might influence the sensorial properties of the product due to the possibility of growth and lactic acid production by probiotic bacteria. © 2013 Institute of Food Technologists®

Carbon footprint of Canadian dairy products: calculations and issues.

Vergé, X P C; Maxime, D; Dyer, J A; Desjardins, R L; Arcand, Y; Vanderzaag, A

2013-09-01

The Canadian dairy sector is a major industry with about 1 million cows. This industry emits about 20% of the total greenhouse gas (GHG) emissions from the main livestock sectors (beef, dairy, swine, and poultry). In 2006, the Canadian dairy herd produced about 7.7 Mt of raw milk, resulting in about 4.4 Mt of dairy products (notably 64% fluid milk and 12% cheese). An integrated cradle-to-gate model (field to processing plant) has been developed to estimate the carbon footprint (CF) of 11 Canadian dairy products. The on-farm part of the model is the Unified Livestock Industry and Crop Emissions Estimation System (ULICEES). It considers all GHG emissions associated with livestock production but, for this study, it was run for the dairy sector specifically. Off-farm GHG emissions were estimated using the Canadian Food Carbon Footprint calculator, (cafoo)(2)-milk. It considers GHG emissions from the farm gate to the exit gate of the processing plants. The CF of the raw milk has been found lower in western provinces [0.93 kg of CO2 equivalents (CO2e)/L of milk] than in eastern provinces (1.12 kg of CO2e/L of milk) because of differences in climate conditions and dairy herd management. Most of the CF estimates of dairy products ranged between 1 and 3 kg of CO2e/kg of product. Three products were, however, significantly higher: cheese (5.3 kg of CO2e/kg), butter (7.3 kg of CO2e/kg), and milk powder (10.1 kg of CO2e/kg). The CF results depend on the milk volume needed, the co-product allocation process (based on milk solids content), and the amount of energy used to manufacture each product. The GHG emissions per kilogram of protein ranged from 13 to 40 kg of CO2e. Two products had higher values: cream and sour cream, at 83 and 78 kg of CO2e/kg, respectively. Finally, the highest CF value was for butter, at about 730 kg of CO2e/kg. This extremely high value is due to the fact that the intensity indicator per kilogram of product is high and that butter is almost exclusively

Some non-thermal microbial inactivation methods in dairy products

International Nuclear Information System (INIS)

Yangilar, F.; Kabil, E.

2013-01-01

During the production of dairy products, some thermal processes such as pasteurization and sterilization are used commonly to inactive microorganisms. But as a result of thermal processes, loss of nutrient and aroma, non-enzymatic browning and organoleptic differentiation especially in dairy products are seen. Because of this, alternative methods are needed to provide microbial inactivation and as major problems are caused by high temperatures, non-thermal processes are focused on. For this purpose, some methods such as high pressure (HP), pulsed light (PL), ultraviolet radiation (UV), supercritical carbon dioxide (SC-CO2) or pulsed electric field (PEF) are used in food. These methods products are processed in ambient temperature and so not only mentioned losses are minimized but also freshness and naturality of products can be preserved. In this work, we will try to be given information about methods of non-thermal microbial inactivation of dairy products. (author) [tr

Processing Challenges and Opportunities of Camel Dairy Products

Directory of Open Access Journals (Sweden)

Tesfemariam Berhe

2017-01-01

Full Text Available A review on the challenges and opportunities of processing camel milk into dairy products is provided with an objective of exploring the challenges of processing and assessing the opportunities for developing functional products from camel milk. The gross composition of camel milk is similar to bovine milk. Nonetheless, the relative composition, distribution, and the molecular structure of the milk components are reported to be different. Consequently, manufacturing of camel dairy products such as cheese, yoghurt, or butter using the same technology as for dairy products from bovine milk can result in processing difficulties and products of inferior quality. However, scientific evidence points to the possibility of transforming camel milk into products by optimization of the processing parameters. Additionally, camel milk has traditionally been used for its medicinal values and recent scientific studies confirm that it is a rich source of bioactive, antimicrobial, and antioxidant substances. The current literature concerning product design and functional potential of camel milk is fragmented in terms of time, place, and depth of the research. Therefore, it is essential to understand the fundamental features of camel milk and initiate detailed multidisciplinary research to fully explore and utilize its functional and technological properties.

Association of trypanosomosis risk with dairy cattle production in western Kenya

Directory of Open Access Journals (Sweden)

G.L. Mugunieri

2005-09-01

Full Text Available Dairy cattle reared in western Kenya are exposed to medium to high levels of trypanosomosis risk. The social background, farm characteristics and dairy cattle productivity of 90 and 30 randomly selected farmers from medium- and high-risk trypanosomosis areas, respectively, were compared. All the 120 farmers were visited between July and August 2002. Data analysis was performed using descriptive statistics and analysis of variance. The results showed that increased trypanosomosis risk represented by an increase in disease prevalence in cattle of 1% to 20 % decreased the density of dairy cattle by 53 % and increased the calving interval from 14 to 25 months. The increased risk was also associated with a significant increase in cattle mortalities and in a lactation period of 257 to 300 days. It was concluded that removal of the trypanosomosis constraint on dairy production would lead to expansion of dairying since the domestic demand for dairy products is expected to increase.

A method to define breeding goals for sustainable dairy cattle production.

Science.gov (United States)

Nielsen, H M; Christensen, L G; Odegård, J

2006-09-01

The objective of this study was to present a method to define breeding goals for sustainable dairy cattle production by adding nonmarket values to market economic values for functional traits in the breeding goal. A nonmarket value can represent the value of improved animal welfare or societal influences for animal production. The nonmarket value for mastitis resistance, conception rate, and stillbirth were derived based on how much farmers or breeding companies were willing to lose in selection response for milk yield to improve functional traits. The desired response for milk yield corresponding to a given percent loss was obtained using desired gain indices. By allowing a 5% loss in the selection response for milk yield, the nonmarket value was found to be 40.4 euro for mastitis resistance, 16.1 euro for conception rate, and 9.7 euro for stillbirth. The nonmarket value increased proportionally with increasing loss in the selection response for milk yield, but the selection response was lower for conception rate than for mastitis resistance because of differences in market economic value and heritability. To increase the response for conception rate, the nonmarket value was also derived for 2 situations, in which the desired responses for milk yield, mastitis resistance, and conception rate were specified. The method can be used to define breeding goals for sustainable production and to increase the response for traits that are at critically low levels. When defining breeding goals for sustainable production, breeding organizations should predict the selection response based on market economic value and add non-market value for traits with unacceptable selection responses.

2018-01-29

In the present population-based study including 70-year-old men and women, total dairy product intake was associated with a weak positive association with tibia trabecular and cortical cross-sectional areas. Milk consumption has recently been suggested to increase fracture risk. Therefore, we aimed to investigate associations between dairy product consumption and peripheral bone properties. Furthermore, we explored whether consumption of milk and fermented dairy products affected bone properties differently. The Healthy Aging Initiative is a population-based, cross-sectional study investigating the health of 70-year-old men and women. Out of the 2904 individuals who met the inclusion criteria, data on self-reported daily dairy product consumption (dl/day), peripheral quantitative computed tomography (pQCT) examinations at the 4 and 66% scan sites of the tibia and radius, and dual-energy X-ray absorptiometry (DXA) scans were collected from 2040 participants. Associations between dairy product consumption and bone properties were examined using multiple linear regression models adjusted for sex, muscle area, meal size, dietary protein proportion, current smoking status, and objectively measured physical activity. Total dairy product intake was associated with larger trabecular (2.296 (95% CI, 0.552-4.039) mm 2 , per dl/day increase, p = 0.01) and cortical cross-sectional areas (CSAs) in the tibia (1.757 (95% CI, 0.683-2.830 mm 2 , p = 0.001) as measured by pQCT and higher areal bone mineral density (aBMD) of the radius (3.231 (95% CI, 0.764-5.698) mg/cm 2 , p = 0.01) as measured by DXA. No other measurement in the tibia, radius, femoral neck, or lower spine was associated significantly with dairy product intake. Bone properties did not differ according to the type of dairy product consumed. No evidence of a negative association between dairy product consumption and bone health was found. Furthermore, total dairy product consumption was associated with

Kim, Kyungwon; Reicks, Marla; Sjoberg, Sara

2003-01-01

The purpose of this study was to explain intention to consume dairy products and consumption of dairy products by older adults using the Theory of Planned Behavior (TPB). The factors examined were attitudes, subjective norms, and perceived behavioral control. A cross-sectional questionnaire was administered. Community centers with congregate dining programs, group classes, and recreational events for older adults. One hundred and sixty-two older adults (mean age 75 years) completed the questionnaire. Subjects were mostly women (76%) and white (65%), with about half having less than a high school education or completing high school. Variables based on the TPB were assessed through questionnaire items that were constructed to form scales measuring attitudes, subjective norms, perceived behavioral control, and intention to consume dairy products. Dairy product consumption was measured using a food frequency questionnaire. Regression analyses were used to determine the association between the scales for the 3 variables proposed in the TPB and intention to consume and consumption of dairy products; the alpha level was set at.05 to determine the statistical significance of results. Attitudes toward eating dairy products and perceived behavioral control contributed to the model for predicting intention, whereas subjective norms did not. Attitudes toward eating dairy products were slightly more important than perceived behavioral control in predicting intention. In turn, intention was strongly related to dairy product consumption, and perceived behavioral control was independently associated with dairy product consumption. These results suggest the utility of the TPB in explaining dairy product consumption for older adults. Nutrition education should focus on improving attitudes and removing barriers to consumption of dairy products for older adults.

A 100-Year Review: Yogurt and other cultured dairy products.

Aryana, Kayanush J; Olson, Douglas W

2017-12-01

The history of the last 100 years of the science and technology of yogurt, sour cream, cultured butter, cultured buttermilk, kefir, and acidophilus milk has been one of continuous development and improvement. Yogurt leads the cultured dairy product category in terms of volume of production in the United States and recent research activity. Legal definitions of yogurt, sour cream and acidified sour cream, and cultured milk, including cultured buttermilk, are presented in the United States Code of Federal Regulations and summarized here. A tremendous amount of research has been done on traditional and novel ingredients, starter cultures and probiotics, mix processing, packaging, chemical aspects, physical and sensory properties, microstructure, specialized products, composition, quality and safety of yogurt and various manufacturing methods, addition of flavorings, viscosity measurements, and probiotic use for sour cream. Over time, there have arisen alternative manufacturing methods, flavor problems, addition of flavorings, and use of probiotics for cultured buttermilk. Many health benefits are provided by yogurt and other cultured dairy products. One hundred years of testing and development have led to wider uses of cultured dairy products and new processing methods for enhanced shelf life and safety. Future research directions will likely include investigating the effects of probiotic dairy products on gut microbiota and overall health. Copyright © 2017 American Dairy Science Association.

Kariuki, C M; van Arendonk, J A M; Kahi, A K; Komen, H

2017-06-01

Dairy cattle industries contribute to food and nutrition security and are a source of income for numerous households in many developing countries. Selective breeding can enhance efficiency in these industries. Developing dairy industries are characterized by diverse production and marketing systems. In this paper, we use weighted goal aggregating procedure to derive consensus trait preferences for different producer categories and processors. We based the study on the dairy industry in Kenya. The analytic hierarchy process was used to derive individual preferences for milk yield (MY), calving interval (CIN), production lifetime (PLT), mature body weight (MBW), and fat yield (FY). Results show that classical classification of production systems into large-scale and smallholder systems does not capture all differences in trait preferences. These differences became apparent when classification was based on productivity at the individual animal level, with high and low intensity producers and processors as the most important groups. High intensity producers had highest preferences for PLT and MY, whereas low intensity producers had highest preference for CIN and PLT; processors preferred MY and FY the most. The highest disagreements between the groups were observed for FY, PLT, and MY. Individual and group preferences were aggregated into consensus preferences using weighted goal programming. Desired gains were obtained as a product of consensus preferences and percentage genetic gains (G%). These were 2.42, 0.22, 2.51, 0.15, and 0.87 for MY, CIN, PLT, MBW, and FY, respectively. Consensus preferences can be used to derive a single compromise breeding objective for situations where the same genetic resources are used in diverse production and marketing circumstances.

Yogurts, fermented milk beverages, and fermented milks have great similarity and are widely accepted by Brazilian population, but the factors that influence their choice and consumption are unknown. In this sense, the present study aimed to identify the main aspects involved in consumers' perception of 3 different products, comparing the findings by using the 2 fast qualitative methods, word association and projective mapping, and a standard method, focus group. The tasks were performed by different participants through graphic stimuli (word association and projective mapping) and focus interviews (focus group). Results showed that all the 3 methodologies identified numerous intrinsic and extrinsic factors that influence the consumer choices regarding fermented dairy products. Major dimensions were closely related to the sensory aspects, emotional factors, perception of benefits, and composition, among others. It is noteworthy that the stimuli related to fermented milk beverages evoked rejecting responses, possibly due to the dissociation between information and consumers' expectation. Although minor differences were observed between the number and type of dimensions that were obtained, similar conclusions can be drawn from all 3 sensory methods, which shows the relevance of qualitative and projective methods for investigation of consumers' perception. These findings can help dairy companies to provide subsidies and guidelines for the reformulation of their products, marketing strategies, and improvement in the communication between producers and consumers from different fermented dairy products.

Full Text Available This paper presents a comparative analysis of the intensity of the production organization between dairy farms conducting agricultural activity in organic and conventional production systems. Study groups of farms were located in the southern (fifteen organic farms, central and eastern part of Poland (fifteen conventional farms. The study was conducted in the form of a directed interview in the marketing year 2010/2011. Area, structure of land use and crop, livestock and the size of plant and animal in the production global and commodity were specified. The analysis showed a lot of differences between the two systems of production, from the area of farm and structure of land use and finally the production outputs. Basic statistical analysis was also conducted. It showed a significant negative correlation between the area of agricultural land and a positive correlation between the livestock and intensity of organisation of production. However, the correlation coefficients between the studied variables in the analysed farm groups differed from each other.

An assessment of the association between the intake of milk or dairy products and bone density or the risk of fractures on the basis of epidemiological studies revealed the following findings:(1)a sufficient prepubertal intake of milk or dairy products could contribute to the increased bone growth and maximized peal bone mass because the intake of calcium in the corresponding stage in Japan is inadequate;(2)adequate milk intake could contribute to the maintenance of peal bone mass among menstruating adult females and the decrease of bone loss in postmenopausal females. Adequate milk intake could contribute to the decrease of aging-induced bone loss in elderly males, though there is no sufficient scientific evidence;and(3)a meta-analysis indicated no correlation between the increased milk intake and decreased risks of hip fractures in the elderly. As the intake of milk or dairy products in the Japanese elderly is rather less than that reported by the meta-analysis, the minimal intake of milk or dairy products is anticipated to elevate the risk of fractures in middle-aged or elderly males and females although the scientific evidence is inadequate.

Šimun Zamberlin

2012-06-01

Full Text Available The characteristics of bacterial populations in raw milk at the time of processing has a significant influence on shelf-life, organoleptic quality, spoilage and yields of raw milk, processed milk as well as on the other dairy products. Unfortunately, cold and extended storage of raw milk, as a common practice in dairy sector today, favour the growth of psychrotrophic bacteria. Therefore, their count in the refrigerated milk is more than the ideal limit of 10 % of the mesophilic count. Psychrotrophic bacteria are generally able to form extracellular or intracellular thermo-resistant enzymes (proteases, lipases, phospolipases which can contribute to milk and dairy products spoilage. In addition, besides exhibiting spoilage features, some species belonging to the psychrotrops are considered as emerging pathogens that carry innate resistance to antibiotics or produce toxins. In sense of quality, psychrotrophic bacteria have become major problem for today’s dairy industry as leading cause in spoilage of cold-storage milk and dairy products. This review article focuses on the impact of psychrotrops on quality problems associated with raw milk as well as on th final dairy products. Means of controlling the dominant psychrotrophic species responsible for undesirable activities in milk and dairy products were also discussed.

2017-12-01

A resilient US dairy industry will be underpinned by forage and crop production systems that are economically, environmentally, and socially sustainable. Land use for production of perennial and annual forages and grains for dairy cattle must evolve in response to multiple food security and environmental sustainability issues. These include increasing global populations; higher incomes and demand for dairy and other animal products; climate change with associated temperature and moisture changes; necessary reductions in carbon and water footprints; maintenance of soil quality and soil nutrient concerns; and competition for land. Likewise, maintaining producer profitability and utilizing practices accepted by consumers and society generally must also be considered. Predicted changes in climate and water availability will likely challenge current feed and dairy production systems and their national spatial distribution, particularly the western migration of dairy production in the late 20th century. To maintain and stabilize profitability while reducing carbon footprint, particularly reductions in methane emission and enhancements in soil carbon sequestration, dairy production will need to capitalize on genetic and management innovations that enhance forage and grain production and nutritive value. Improved regional and on-farm integration of feed production and manure utilization is needed to reduce environmental nitrogen and phosphorus losses and mitigate greenhouse gas emissions. Resilient and flexible feed production strategies are needed to address each of these challenges and opportunities to ensure profitable feeding of dairy cattle and a sustainable dairy industry.

A qualitative risk assessment approach for Swiss dairy products: opportunities and limitations.

Science.gov (United States)

Menéndez González, S; Hartnack, S; Berger, T; Doherr, M; Breidenbach, E

2011-05-01

Switzerland implemented a risk-based monitoring of Swiss dairy products in 2002 based on a risk assessment (RA) that considered the probability of exceeding a microbiological limit value set by law. A new RA was launched in 2007 to review and further develop the previous assessment, and to make recommendations for future risk-based monitoring according to current risks. The resulting qualitative RA was designed to ascertain the risk to human health from the consumption of Swiss dairy products. The products and microbial hazards to be considered in the RA were determined based on a risk profile. The hazards included Campylobacter spp., Listeria monocytogenes, Salmonella spp., Shiga toxin-producing Escherichia coli, coagulase-positive staphylococci and Staphylococcus aureus enterotoxin. The release assessment considered the prevalence of the hazards in bulk milk samples, the influence of the process parameters on the microorganisms, and the influence of the type of dairy. The exposure assessment was linked to the production volume. An overall probability was estimated combining the probabilities of release and exposure for each combination of hazard, dairy product and type of dairy. This overall probability represents the likelihood of a product from a certain type of dairy exceeding the microbiological limit value and being passed on to the consumer. The consequences could not be fully assessed due to lack of detailed information on the number of disease cases caused by the consumption of dairy products. The results were expressed as a ranking of overall probabilities. Finally, recommendations for the design of the risk-based monitoring programme and for filling the identified data gaps were given. The aims of this work were (i) to present the qualitative RA approach for Swiss dairy products, which could be adapted to other settings and (ii) to discuss the opportunities and limitations of the qualitative method. © 2010 Blackwell Verlag GmbH.

The economics of optimal health and productivity in the commercial dairy.

Science.gov (United States)

Galligan, D T

1999-08-01

Dairy production practices are changing; in order to remain viable, producers must optimise the health and productivity of dairy herds in economic terms. Health care is important in economic terms because disease can substantially reduce the productivity of individual animals. Preventive disease control programmes can thus result in economic gains for the dairy producer. The author describes new approaches to preventing postpartum diseases and dealing with fertility problems which can result from these diseases. Other aspects of dairy production are also changing, employing new technologies where these are judged to be profitable. Innovations include: the use of bovine somatotropin; systematic breeding/culling programmes; new mathematical modelling techniques to determine optimum feed composition and to define optimal growth levels for accelerated heifer-rearing programmes; the use of computers to collect, store and analyse data on animal production and health; and semen selection programmes. Increasing awareness of bio-security is also vital, not least because of the large investment present in dairy herds. Whatever practices are employed, they must offer economic returns to producers that compete with alternative uses of capital. Optimal levels of disease control must be determined for a particular production situation, taking into account not only the economic health of the producer, but also the well-being of the animals.

2003-01-01

Full Text Available Nutritive quality and variety of food intake are the most important issues for young people growing and developing. Nutritional habits of each individual are also very important. High values of proteins, mineral matters and vitamins in milk show the importance of milk consumption in meals for children and young people.In order to gain a precise insight into nutritive status of young people in Croatian boarding schools, a "closed type group" was selected. The examined groups included girls and boys at the age of 14-18 years, accommodated in 39 boarding schools. The questionnaires, organised in order to determine preferences in consumption of different food groups including milk and dairy products, are conducted as well. From the meals analysed one can recommend the improvements in meal preferences. Average values per day showed that 52 % of girls and 63 % of boys consume milk and dairy products only if includedin boarding school meals. Only 27 % of girls and 21 % of boys consumed milk or dairy products on daily basis. Results of milk and dairy product preferences are different with regards to different regions of Croatia. Region 3, Lika and Gorski Kotar, shows the highest values of dairy products consumption. The aim of the work is to determine quality of the energy and nutritive intake by nutrition analysis, and to determine nutritional irregularities with a special reference to milk and dairy products consumption. Furthermore, nutritional improvements, by including the results of meal preferences in accordance with the needs and DRI recommendations considering gender and age, are proposed.

Across the world, more dairy producers are considering on-farm dairy processing to add value to the milk produced on their farms. Dairy producers may bottle milk or process their milk into cheese, ice cream, butter, yogurt, or cream. The primary objective of this research was to establish a series of sound factors or indicators of success for those considering on-farm processing. A survey was employed to collect opinions and advice from managers of on-farm processing enterprises. Surveys were distributed online (n=120), with 31 surveys returned, accounting for a 25.8% response rate. Most (64%) respondents had been involved in on-farm dairy processing for less than 10 yr. Sixty-one percent of respondents attained a positive cash flow in 1 to 3 yr. The primary products manufactured were cheese (69%), milk (59%), ice cream (31%), yogurt (25%), and butter (21%). Factors influencing the decision to start an on-farm dairy processing enterprise included commodity milk prices (61%), desire to work with the public (41%), an opportunity to promote the dairy industry (39%), a desire to maintain or expand a small family operation (29%), and product differentiation (16%). Respondents cited dealing with regulations (26%), product marketing (19%), manufacturing technicalities (19%), and securing funding (17%) as the most difficult parts of starting the business. Open-ended responses provided by the respondents of this survey were also documented to give future dairy producers advice. The most common advice to future on-farm processors was to work on realistic business plans, develop and follow realistic budgets, and observe and use market surveys within the industry. These results provide a useful array of information for future on-farm dairy processing enterprises. Copyright © 2013 American Dairy Science Association. Published by Elsevier Inc.

Mäkinen, Outi Elina; Wanhalinna, Viivi; Zannini, Emanuele; Arendt, Elke Karin

2016-01-01

A growing number of consumers opt for plant-based milk substitutes for medical reasons or as a lifestyle choice. Medical reasons include lactose intolerance, with a worldwide prevalence of 75%, and cow's milk allergy. Also, in countries where mammal milk is scarce and expensive, plant milk substitutes serve as a more affordable option. However, many of these products have sensory characteristics objectionable to the mainstream western palate. Technologically, plant milk substitutes are suspensions of dissolved and disintegrated plant material in water, resembling cow's milk in appearance. They are manufactured by extracting the plant material in water, separating the liquid, and formulating the final product. Homogenization and thermal treatments are necessary to improve the suspension and microbial stabilities of commercial products that can be consumed as such or be further processed into fermented dairy-type products. The nutritional properties depend on the plant source, processing, and fortification. As some products have extremely low protein and calcium contents, consumer awareness is important when plant milk substitutes are used to replace cow's milk in the diet, e.g. in the case of dairy intolerances. If formulated into palatable and nutritionally adequate products, plant-based substitutes can offer a sustainable alternative to dairy products.

Diversity and Control of Spoilage Fungi in Dairy Products: An Update

Science.gov (United States)

Valence, Florence; Mounier, Jérôme

2017-01-01

Fungi are common contaminants of dairy products, which provide a favorable niche for their growth. They are responsible for visible or non-visible defects, such as off-odor and -flavor, and lead to significant food waste and losses as well as important economic losses. Control of fungal spoilage is a major concern for industrials and scientists that are looking for efficient solutions to prevent and/or limit fungal spoilage in dairy products. Several traditional methods also called traditional hurdle technologies are implemented and combined to prevent and control such contaminations. Prevention methods include good manufacturing and hygiene practices, air filtration, and decontamination systems, while control methods include inactivation treatments, temperature control, and modified atmosphere packaging. However, despite technology advances in existing preservation methods, fungal spoilage is still an issue for dairy manufacturers and in recent years, new (bio) preservation technologies are being developed such as the use of bioprotective cultures. This review summarizes our current knowledge on the diversity of spoilage fungi in dairy products and the traditional and (potentially) new hurdle technologies to control their occurrence in dairy foods.

2015-01-01

Full Text Available Description of the subject. Due to the potential hazards caused by pathogenic bacteria, farm dairy production remains a challenge from the point of view of food safety. As part of a public program to support farm diversification and short food supply chains, farm dairy product samples including yogurt, ice cream, raw-milk butter and cheese samples were collected from 318 Walloon farm producers between 2006 and 2014. Objectives. Investigation of the microbiological quality of the Belgian dairy products using the guidelines provided by the European food safety standards. Method. The samples were collected within the framework of the self-checking regulation. In accordance with the European Regulation EC 2073/2005, microbiological analyses were performed to detect and count Enterobacteriaceae, Listeria monocytogenes, Salmonella spp., Escherichia coli and Staphylococcus aureus. Results. Even when results met the microbiological safety standards, hygienic indicator microorganisms like E. coli and S. aureus exceeded the defined limits in 35% and 4% of butter and cheese samples, respectively. Unsatisfactory levels observed for soft cheeses remained higher (10% and 2% for S. aureus and L. monocytogenes respectively than those observed for pressed cheeses (3% and 1% and fresh cheeses (3% and 0% (P ≥ 0.05. Furthermore, the percentages of samples outside legal limits were not significantly higher in the summer months than in winter months for all mentioned bacteria. Conclusions. This survey showed that most farm dairy products investigated were microbiologically safe. However, high levels of hygiene indicators (e.g., E. coli in some products, like butter, remind us of applying good hygienic practices at every stage of the dairy production process to ensure consumer safety.

Full Text Available The aim of this work was to determine the portion of milk and dairyproducts as a source of macronutrients, energy, vitamins and minerals in average hotel menus for some category of hotel guests. For this purpose the evaluation of 66 whole day meals (breakfast, lunch and supper on daily menus was made. Meals were therefore mathematically and statistically analysed and compared with recommendations (RDA and DRI for middle aged and elderly guests, both genders. The obtained results indicated that the meals should be balanced according to nutritional principles, because of too high energy share derived from fats (average 47.95% while just about 37.57% of daily energy was from carbohydrates origin. The energy values were much higher than recommendations for both genders, respectively. The energy share from milk and dairy products origin was 11% of total energy what should be considered as a suitable. The most served dairy product was milk while the ice-cream took the second place. It is necessary to increase the yogurt and similar fermented products consumption, especially for the elderly guests. With milk and dairy products consumption males and females fulfill 92% RDA for calcium, and 61.80 % DRI for elderly, respectively.

Dairy in a sustainable diet: a question of balance.

Science.gov (United States)

van Hooijdonk, Toon; Hettinga, Kasper

2015-08-01

The demand for dairy products is growing rapidly, especially in emerging markets. Dairy products are nutrient rich and, therefore, an important food group for ensuring nutrient security in the future. In many countries, dairy contributes significantly to nutrient intake. Meta-analyses have shown that consumption of dairy may reduce the risk of chronic diseases and thereby lower healthcare costs. Milk production and processing contribute to greenhouse gas emissions, estimated at 2.7% (cradle-to-retail) of the world's total. Evaluating the position of dairy in the diet should take into account the impact of both nutritional and environmental factors. Local conditions are also important; in many parts of the world, the cow is an efficient converter of human-inedible resources into nutrient-dense food. Increased productivity of cows is a decisive factor in realizing sufficient milk production with optimal resource efficiency and minimal greenhouse gas emission. Models that optimize total diets, rather than individual food products, for their nutritional and environmental impact are the preferred approach for developing realistic alternative consumption strategies. © The Author(s) 2015.

2017-12-01

Full Text Available Dairy industry is one of the essential global industries with considerably important implications for world economy where the dairy supply chains (DSC cover every stage of the food system starting from the milk production at farmer level to final consumption. For achieving success in the dairy supply chain, it is needed to focus on critical factors (CFs that are necessary for an organization to achieve its corporate goals with continually improving the operational performance. In this context, the current study is an attempt to identify the critical factors causing low-productivity in dairy supply chains. After comprehensive literature review and pilot studies in some dairy industries located in northern region of India, a total of 32 critical factors have been identified. A structured questionnaire consisting of 32 CFs have been circulated and the data has been collected from select cooperative dairy units. Further, only eight major critical factors have been carried forward for AHP analysis based on the data collected. The factor having higher weightage score is considered as major CF. The findings of this study indicate that the poor logistics and transportation facilities is the most critical factor as productivity barrier in the context of coop. milk processing units in northern India. This research study would be useful for the dairy professionals & managers of milk processing units to manage their production operations effectively by considering the identified CFs.

Katla, A K; Kruse, H; Johnsen, G; Herikstad, H

2001-07-20

Commercial starter culture bacteria are widely used in the production of dairy products and could represent a potential source for spread of genes encoding resistance to antimicrobial agents. To learn more about the antimicrobial susceptibility of starter culture bacteria used in Norwegian dairy products, a total of 189 isolates of lactic acid bacteria were examined for susceptibility to ampicillin, penicillin G, cephalothin, vancomycin, bacitracin, gentamicin, streptomycin, erythromycin, tetracycline, chloramphenicol, quinupristin/dalfopristin, ciprofloxacin, trimethoprim and sulphadiazine using Etest for MIC determination. Most of the isolates (140) originated from 39 dairy products (yoghurt, sour cream, fermented milk and cheese), while 49 were isolated directly from nine commercial cultures. The bacteria belonged to the genera Lactobacillus, Lactococcus, Leuconostoc and Streptococcus. Only one of the 189 isolates was classified as resistant to an antimicrobial agent included in the study. This isolate, a lactobacillus, was classified as high level resistant to streptomycin. The remaining isolates were not classified as resistant to the antimicrobial agents included other than to those they are known to have a natural reduced susceptibility to. Thus, starter culture bacteria in Norwegian dairy products do not seem to represent a source for spread of genes encoding resistance to antimicrobial agents.

Full Text Available Fermented dairy products provide nutrients in our diet, some of which are produced by the action of microorganisms during fermentation. These products can be populated by a diverse microbiota that impacts the organoleptic and physicochemical characteristics foods as well as human health. Acidification is carried out by starter lactic acid bacteria (LAB whereas other LAB, moulds, and yeasts become dominant during ripening and contribute to the development of aroma and texture in dairy products. Probiotics are generally part of the nonstarter microbiota, and their use has been extended in recent years. Fermented dairy products can contain beneficial compounds, which are produced by the metabolic activity of their microbiota (vitamins, conjugated linoleic acid, bioactive peptides, and gamma-aminobutyric acid, among others. Some microorganisms can also release toxic compounds, the most notorious being biogenic amines and aflatoxins. Though generally considered safe, fermented dairy products can be contaminated by pathogens. If proliferation occurs during manufacture or storage, they can cause sporadic cases or outbreaks of disease. This paper provides an overview on the current state of different aspects of the research on microorganisms present in dairy products in the light of their positive or negative impact on human health.

Dairy products consumption and risk of type 2 diabetes: systematic review and dose-response meta-analysis.

Directory of Open Access Journals (Sweden)

Dengfeng Gao

Full Text Available BACKGROUND: The consumption of dairy products may influence the risk of type 2 diabetes mellitus (T2DM, but inconsistent findings have been reported. Moreover, large variation in the types of dairy intake has not yet been fully explored. METHODS AND RESULTS: We conducted a systematic review and meta-analysis to clarify the dose-response association of dairy products intake and T2DM risk. We searched PubMed, EMBASE and Scopus for studies of dairy products intake and T2DM risk published up to the end of October 2012. Random-effects models were used to estimate summary relative risk (RR statistics. Dose-response relations were evaluated using data from different dairy products in each study. We included 14 articles of cohort studies that reported RR estimates and 95% confidence intervals (95% CIs of T2DM with dairy products intake. We found an inverse linear association of consumption of total dairy products (13 studies, low-fat dairy products (8 studies, cheese (7 studies and yogurt (7 studies and risk of T2DM. The pooled RRs were 0.94 (95% CI 0.91-0.97 and 0.88 (0.84-0.93 for 200 g/day total and low-fat dairy consumption, respectively. The pooled RRs were 0.80 (0.69-0.93 and 0.91 (0.82-1.00 for 30 g/d cheese and 50 g/d yogurt consumption, respectively. We also found a nonlinear association of total and low-fat dairy intake and T2DM risk, and the inverse association appeared to be strongest within 200 g/d intake. CONCLUSION: A modest increase in daily intake of dairy products such as low fat dairy, cheese and yogurt may contribute to the prevention of T2DM, which needs confirmation in randomized controlled trials.

Prospective studies have reported an inverse association between the consumption of total dairy products and milk and the risk of colorectal cancer (CRC). Nonetheless, there is little and inconsistent evidence regarding subtypes of dairy product and CRC risk. We assessed the associations between the consumption of total dairy products, their different subtypes and CRC risk in older Mediterranean individuals at high cardiovascular risk. We analyzed data from 7,216 men and women (55-80 years) without CRC at baseline from the PREvención con DIeta MEDiterránea study. Individuals were recruited between 2003 and 2009 and followed up until December 2012. At baseline and yearly thereafter, consumption of total and specific dairy products was assessed using a validated 137-item food-frequency questionnaire. Cox proportional hazards ratios (HRs) of CRC incidence were estimated for tertiles of mean consumption of dairy products during the follow-up. During a median [interquartile range] follow-up of 6.0 [4.4-7.3] years, we documented 101 incident CRC cases. In the multivariable-adjusted models, HRs and 95% confidence intervals (CIs) of CRC for the comparison of extreme tertiles of total dairy product and low-fat milk consumption were 0.55 (95% CI: 0.31-0.99; p-trend = 0.037) and 0.54 (95% CI: 0.32-0.92; p-trend = 0.022), respectively. No significant associations with other dairy products (whole-fat and low-fat dairy products; total, low-fat and whole-fat yogurt; cheese; total, low-fat and whole-fat milk; concentrated full-fat dairy products, sugar-enriched dairy products and fermented dairy products) were found. A high consumption of total dairy products and low-fat milk was significantly associated with a reduced CRC risk. © 2018 UICC.

Foodborne pathogens are a major threat to food safety, especially in developing countries where hygiene and sanitation facilities are often poor. Salmonella enterica, Escherichia coli O157:H7 and Shigella spp. are among the major causes of outbreaks of foodborne diseases. This large-scale study investigated the prevalence of these foodborne pathogens in meat (beef and chicken) and dairy products collected from street vendors, butchers, retail markets and slaughterhouses in Egypt. A total of 1600 food samples (800 meat products and 800 dairy products) were analyzed using culture and PCR based methods. S. enterica, E. coli O157:H7 and Shigella spp. were detected in 69 (4.3%), 54 (3.4%) and 27 (1.7%) samples respectively. S. enterica serovar Typhimurium, S. enterica serovar Enteritidis, S. enterica serovar Infantis and non-typable serovars were detected in 28 (1.8%), 22 (1.4%), 16 (1.0%) and 3 (0.1%) samples respectively. All E. coli O157:H7 isolates were positive for stx1 and/or stx2 virulence toxin genes. Shigella flexneri, Shigella sonnei and Shigella dysenteriae were detected in 18 (1.2%), 7 (0.4%) and 2 (0.1%) samples respectively. The incidences of S. enterica and Shigella spp. were higher in meat products (53; 6.6% and 16; 2.0%, respectively) than in dairy products (16; 2.0% and 11; 1.4%, respectively), while, E. coli O157:H7 was higher in dairy products (29; 3.6%) than in meat products (25; 3.1%). The incidence of foodborne pathogens in meat and dairy products was determined in a large-scale survey in Africa. © 2013.

Production of selenium-enriched milk and dairy products

Directory of Open Access Journals (Sweden)

Csapó J.

2015-01-01

Full Text Available Until the middle of the last century, selenium was considered to be toxic, but recently it turned out to be a micronutrient with important physiological effects, whose lack impedes the functioning of several enzymes, while in the case of a prolonged deficiency, disease processes can also occur in the body. Hungary belongs to the selenium-deficient regions in Europe; therefore, our aim was to contribute to the improvement of selenium supply of the population through increasing the selenium content of milk and dairy products. A daily supplementation of 1-6 mg organic selenium to the feed of dairy cows increases the selenium content of milk from the value of 18 μg/kg to 94 μg/kg in 8 weeks, decreasing again to the initial value in 6 weeks after stopping the supplementation.

Factors influencing Adoption of Napier Grass in Smallholder Dairy Farming in Kiambu District, Kenya

Irungu, P.; Mbogoh, S.; Staai, S.; Thorpe, W.; Njubi, D.

1999-01-01

Smallholder dairy farming in Kenya accounts for over 70% of the total marketed milk, which amounts to US$400 million at the current exchange rate. Milk production on smallholder dairy farms is usually low. This is mainly attributed to poor nutrition. Planting forages may improve the level of feeding and nutrition and thus raise both farm productivity and overall supply of milk to the growing urban markets. Data from 365 households in Kiambu District were gathered through questionnaire interviews with farmers between June and July 1996 and economic models used to quantitatively evaluate socio-economic and institutional factors postulated to influence the adoption of Napier grass as a forage in the experience and-or channeling interventions thorough dairy co-operative societies and farmer organisations may result in higher adoption rates of dairy cattle fodder. Thus, efforts aimed at promoting planted fodder in other highland areas of Kenya could utilise the results obtained in the present study

The Halal status of additives in milk and dairy products

Directory of Open Access Journals (Sweden)

Midhat Jašić

2007-06-01

Full Text Available The market of halal products in the world keeps growing and there are more and more requests for certifying and proving the halal status of a food product. Halal in Islamic regulations means allowed for eating. Islamic laws related to the food, strictly forbid the use of food originating from pork, alcohol, blood and other products that are not in accordance with Islamic rules. In order to get the halal status, dairy products have to prove that they do not contain raw mater and additives that are forbidden. Level of allowance is related with their status which can be Halal (permitted, Haram (forbidden and Mashbuh (suspected. In establishing the system for Halal foodprocessing, proactive preventive process approach is used. In validation of the process there are analytical methods to prove the origin of the food. Specially difficult is to prove the presence of additives which during the process experience chemical transformations. The ELISA PCR, HLPC methods are used for the validation. This paper presents additives that are the most common in milk processing and can have Haram (forbidden by Islamic rules and Mashbuh (suspected origin.

Full Text Available Aim: The study aimed to assess the prevalence of Listeria spp. in raw milk and traditional non-pasteurized dairy products in Isfahan, Iran. Materials and Methods: A total of 292 samples of raw milk and traditional dairy were examined for the presence of Listeria spp. using a two-step selective enrichment recommended by the United States Department of Agriculture. All isolates were subjected to standard biochemical tests. L. monocytogenes strains were further confirmed by polymerase chain reaction (PCR amplification. Results: Of 292 samples, 21 (7.14% and 4 (1.47% were positive for Listeria spp. and pathogenic L. monocytogenes, respectively. The prevalence of Listeria spp. in raw milk, ice cream, cream, and freni were 5.91 (5.49%, 12.63 (19.04%, 3.27 (11.11% and 1.25 (4%, respectively. Listeria was not detected from yogurt, butter, Kashk, and cheese. Listeria innocua at 16.21 (5.44% was the most prevalent species isolated, followed by L. monocytogenes at 4.21 (19% and L. seeligeri at 1.21 (4.7%. All strains of L. monocytogenes identified by biochemical tests were also confirmed by PCR. Conclusion: The study shows the prevalence of L. monocytogenes in raw milk and traditional dairy products sold in the market. Consumption of raw milk with mild heat treatment or its usage in traditional dishes could pose serious health problems due to lack of appropriate control measures. The lack of knowledge on the risks of listeriosis transmission indicates the need for implementation of a food safety education program. In addition, the Iranian food safety authorities should urgently set up an effective standard to screen all susceptible food products for the presence of Listeria.

Harlia, E.; Rahmah, KN; Suryanto, D.

2018-01-01

Food safety of milk and dairy products is a prerequisite for consumption, which must be free from physical, biological and chemical contamination. Chemical contamination of heavy metals Pb (Plumbum/Lead) and Cd (Cadmium) is generally derived from the environment such as from water, grass, feed additives, medicines and farm equipment. The contamination of milk and dairy products can affect quality and food safety for human consumption. The aim of this research is to investigate contamination of heavy metals Pb and Cd on fresh milk, pasteurized milk, and dodol milk compared with the Maximum Residue Limits (MRL). The methods of this researched was through case study and data obtained analyzed descriptively. Milk samples were obtained from Bandung and surrounding areas. The number of samples used was 30 samples for each product: 30 samples of fresh milk directly obtained from dairy farm, 30 samples of pasteurized milk obtained from street vendors and 30 samples of dodol milk obtained from home industry. Parameters observed were heavy metal residues of Pb and Cd. The results showed that: 1) approximately 83% of fresh milk samples were contaminated by Pb which 57% samples were above MRL and 90% samples were contaminated by Cd above MRL; 2) 67% of pasteurized milk samples were contaminated by Pb below MRL; 3) 60% of dodol milk samples were contaminated by Pb and Cd above MRL.

This survey consisted of data collected from 23 beef harvest plants to document transportation procedures, management practices, and health assessments of market beef and dairy cows and bulls (about n ≅ 7,000 animals). Gooseneck/bumper-pulled trailers were used more often to transport dairy cattle than beef cattle to market whereas tractor-trailers were used more often to transport beef cattle than dairy cattle. All loads (n = 103) met the American Meat Institute Foundation guidelines for spacing. Loads where more than 3% of the cattle slipped during unloading were observed in 27.3% of beef loads and 29.0% of the dairy loads. Beef loads had numerically greater usage of electrical prods (32.4%) versus dairy loads (15.4%) during unloading and were more likely to have a variety of driving aids used more aggressively on them. Fewer cattle had horns, brands, and mud/manure contamination on hides than in the previous survey in 1999. The predominant hide color for beef cows was black (44.2%) whereas the predominant color for dairy cows was the Holstein pattern (92.9%). Fewer cattle displayed evidence of bovine ocular neoplasia (2.9%) than in previous surveys in 1994 (8.5%) and 1999 (4.3%). Knots on live cattle were found less in the round (0.5%) and more in the shoulder region (4.6%) than in 1999 (1.4% and 0.4%, respectively). Dairy cows were more frequently lame in 2007 (48.7%) than 1999 (39.2%) whereas beef cows had numerically less lameness (16.3% vs. 26.6%, respectively). Most beef cows (62.3%) and dairy cows (68.9%) received midpoint body condition scores (3, 4, and 5 for beef; 2 and 3 for dairy). Beef cows had higher numerical percentages of no defects present (72.0%) versus dairy cows (63.0%) when evaluated for a variety of reproductive, health, or management conditions. Continued improvements in several key factors related to transportation, management, and health were observed in this survey, which could result in increased value in market beef and dairy cows

NAFTA Renegotiations: An opportunity for Canadian Dairy?

Directory of Open Access Journals (Sweden)

Eugene Beaulieu

2018-03-01

Full Text Available What are the implications of a renegotiated NAFTA for Canadian dairy producers? Many observers dread the prospect of even the slightest liberalization in the dairy sector. This paper takes a different perspective, arguing that opening Canada’s dairy sector would come with benefits not just for consumers, which is undeniable, but could also transform the industry and lead to a more productive dairy sector in Canada. Canadian dairy producers have been protected domestically through supply management and internationally through import-restricting border controls for over 40 years. This combination of domestic and foreign policies keeps Canadian dairy prices artificially high and allows producers to gain enormously from the system while hitting dairy consumers directly in the pocketbook. These policies are extremely costly for Canadian consumers and benefit the protected domestic dairy producers. Canadian international trade policies result in 200-percent tariffs on imports of many dairy products and almost 300-percent tariffs on over-quota imports of cheese. The OECD estimates that from 2010 to 2016, Canadian trade policy with respect to dairy and the “supply management system” annually transfers over US$2.9 billion from Canadian consumers and taxpayers to milk producers. This is extremely expensive for Canadian consumers and this transfer to Canadian dairy producers underscores why our trade partners have focused on the exorbitant tariffs that support this system. We argue that it is not only consumers that are hurt by the status quo, but that the industry itself can evolve and thrive from increased competition. According to standard trade theory, liberalizing trade in an industry like this leads the least productive producers to exit the industry as the most-productive producers increase market share and expand. These dynamics generate a more competitive and productive industry. We present evidence that these dynamics played out in Canada

Effects of switching between production systems in dairy farming

Directory of Open Access Journals (Sweden)

Antonio Alvarez

2015-05-01

Full Text Available The increasing intensification of dairy farming in Europe has sparked an interest in studying the economic consequences of this process. However, empirically classifying farms as extensive or intensive is not a straightforward task. In recent papers, Latent Class Models (LCM have been used to avoid an ad-hoc split of the sample into intensive and extensive dairy farms. A limitation of current specifications of LCM is that they do not allow farms to switch between different productive systems over time. This feature of the model is at odds with the process of intensification of the European dairy industry in recent decades. We allow for changes of production system over time by estimating a single LCM model but splitting the original panel into two periods, and find that the probability of using the intensive technology increases over time. Our estimation proposal opens up the possibility of studying the effects of intensification not only across farms but also over time.

The overall goal of the project is to develop a computer-based benchmarking and energy and water savings tool (BEST-Dairy) for use in the California dairy industry - including four dairy processes - cheese, fluid milk, butter, and milk powder. BEST-Dairy tool developed in this project provides three options for the user to benchmark each of the dairy product included in the tool, with each option differentiated based on specific detail level of process or plant, i.e., 1) plant level; 2) process-group level, and 3) process-step level. For each detail level, the tool accounts for differences in production and other variables affecting energy use in dairy processes. The dairy products include cheese, fluid milk, butter, milk powder, etc. The BEST-Dairy tool can be applied to a wide range of dairy facilities to provide energy and water savings estimates, which are based upon the comparisons with the best available reference cases that were established through reviewing information from international and national samples. We have performed and completed alpha- and beta-testing (field testing) of the BEST-Dairy tool, through which feedback from voluntary users in the U.S. dairy industry was gathered to validate and improve the tool's functionality. BEST-Dairy v1.2 was formally published in May 2011, and has been made available for free downloads from the internet (i.e., http://best-dairy.lbl.gov).

2016-02-27

Many epidemiologic studies have explored the association between dairy product consumption and the risk of non-Hodgkin lymphoma (NHL), but the results remain controversial. A literature search was performed in PubMed, Web of Science and Embase for relevant articles published up to October 2015. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated with a random-effects model. The dose-response relationship was assessed by restricted cubic spline. A total of 16 articles were eligible for this meta-analysis. The pooled RRs (95% CIs) of NHL for the highest vs. lowest category of the consumption of total dairy product, milk, butter, cheese, ice cream and yogurt were 1.20 (1.02, 1.42), 1.41 (1.08, 1.84), 1.31 (1.04, 1.65), 1.14 (0.96, 1.34), 1.57 (1.11, 2.20) and 0.78 (0.54, 1.12), respectively. In subgroup analyses, the positive association between total dairy product consumption and the risk of NHL was found among case-control studies (RR = 1.41, 95% CI: 1.17-1.70) but not among cohort studies (RR = 1.02, 95% CI: 0.88-1.17). The pooled RRs (95% CIs) of NHL were 1.21 (1.01, 1.46) for milk consumption in studies conducted in North America, and 1.24 (1.09, 1.40) for cheese consumption in studies that adopted validated food frequency questionnaires. In further analysis of NHL subtypes, we found statistically significant associations between the consumption of total dairy product (RR = 1.73, 95% CI: 1.22-2.45) and milk (RR = 1.49, 95% CI: 1.08-2.06) and the risk of diffuse large B-cell lymphoma. The dose-response analysis suggested that the risk of NHL increased by 5% (1.05 (1.00-1.10)) and 6% (1.06 (0.99-1.13)) for each 200 g/day increment of total dairy product and milk consumption, respectively. This meta-analysis suggested that dairy product consumption, but not yogurt, may increase the risk of NHL. More prospective cohort studies that investigate specific types of dairy product consumption are needed to confirm this conclusion.

Full Text Available Summary. The article discusses the construction of algorithms for automated processing of microphotos of dairy products. Automated processing of micro photos of dairy products relevant in the study of the degree of homogenization. Microphotos of dairy products contain information about the distribution of fat globules in the mass fractions. Today, there are some of software products, offering image processing and relieving researchers from routine operations manual data processing. But it need to be adapted for performing the processing of microphotos of dairy products. In this paper we propose to use for processing the application package ImageJ for processing image files taken with digital microscope, and to calculate the statistical characteristics of the proposed use of the software package Statistica. Processing algorithm consists of successive stages of conversion to gray scale, scaling, filtering, binarization, object recognition and statistical processing of the results of recognition. The result of the implemented data processing algorithms is the distribution function of the fat globules in terms of volume or mass fraction, as well as the statistical parameters of the distribution (the mathematical expectation, variance, skewness and kurtosis coefficients. For the inspection of the algorithm and its debugging experimental studieswere carried out. Carries out the homogenization of farm milk at different pressures of homogenization. For each sample were made microphoto sand image processing carried out in accordance with the proposed algorithm. Studies have shown the effectiveness and feasibility of the proposed algorithm in the form of java script for ImageJ and then send the data to a file for the software package Statistica.

Dairy foods represent an important sector of the food market for their nutritional qualities and their organoleptic characteristics, which are often linked to tradition and to region. These products are typically protected by labels such as PDO (Protected Designation of Origin) and PGI (Protected Geographical Indication). Real-time PCR (qPCR) is a fundamental tool in "Food Genomics;" a discipline concerned with the residual DNA in food, which, alongside traditional physical and chemical methods, is frequently used to determine product safety, quality and authenticity. Compared to conventional or "end-point" PCR, qPCR incorporates continuous monitoring of reaction progress, thereby enabling quantification of target DNA. This review describes qPCR applications to the analysis of microbiota, and to the identification of the animal species source of milk from which dairy products have been made. These are important aspects for ensuring safety and authenticity. The various applications of qPCR are discussed, as well as advantages and disadvantages in comparison with other analytical methods.

Full Text Available Prevention of foodborne diseases is a priority for the world health system. In the process of manufacturing milk and dairy products, the most important factor compromising their safety is seeding with a conditionally pathogenic and pathogenic microflora. Salmonella, Escherichia coli, Listeria and other microorganisms that reproduce in dairy products without changing their organoleptic properties are a particular danger. Staphylococcus aureus is an opportunistic, conditionally pathogenic microorganism that often contaminates raw milk and dairy products. The aim of the research presented in this article was to determine the dissemination of S. aureus in milk and milk products of household production in the western regions of Ukraine, to identify the biotypes of S. aureus, production of enterotoxins and the presence of methicillin-resistant strains. S. aureus was isolated on BD Baird-Parker Agar. The biotypes of S. aureus were determined according to Meer. The determination of MRSA was carried out on the chromogenic Agar chromID MRSA ("Biomerioux", Russia. The mecA gene was determined using the LightCycler MRSA Advanced Test with LightCycler 2.0 primer (Roche Molecular Biochemicals, Germany. To determine staphylococcal enterotoxins, the test system RIDASCREENSET A, B, C, D, E (R-Biopharm AG, Darmstadt, Germany was used. We isolated saprophyte staphylococci from milk of raw and dairy products in western regions of Ukraine in 82.7–97.4% of samples. S. aureus is much more rarely isolated from these dairy products, so it was isolated from sour cream at 62.8 ± 0.9%, from milk at 35.5 ± 1.3% and cottage cheese at 23.0 ± 1.6%. Of the most well known biotypes of S. aureus present in milk of raw and dairy products of domestic production, two ecological types were distinguished: human and cattle. In this case S. aureus var. hominis was isolated more often than in S. aureus var. bovis. This gives grounds to believe that the main source of

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.

Land Use Change under Biofuel Policies and a Tax on Meat and Dairy Products: Considering Complexity in Agricultural Production Chains Matters

Directory of Open Access Journals (Sweden)

Ruth Delzeit

2018-02-01

Full Text Available Growing demand for meat and dairy products (MDP, biofuels, and scarcity of agricultural land are drivers of global land use competition. Impacts of policies targeting demand for MDP or biofuels have only been analysed separately. We use the computable general equilibrium model DART-BIO to investigate combined effects, since MDP and biofuel production are closely related via feestock use and co-production of animal feed. We implement four scenarios: (a a baseline scenario; (b halving MDP consumption in industrialised countries by a tax; (c abolishing current biofuel policies; and (d no exogenous land use change. We find that a MDP tax and exogenous land use change have larger effects on land use and food markets than biofuel policies. International trade is affected in all scenarios. With respect to combined effects of a MDP tax and biofuel policies, we find decreasing biodiesel but increasing bioethanol production. In addition, the MDP tax decreases the impact of biofuel policies on agricultural markets and land use. Our results highlight the importance of a detailed representation of different vegetable oils used in biodiesel production and related by-products. Finally, since the MDP tax increases the use of fossil fuels, the net climate mitigation potentials of such a tax should be investigated further.

Full Text Available In recent years, the development of dairy industry in Inner Mongolia has accelerated its economic growth, and its grassland culture has become appealing to the public. As an important support industry for the economic development in tourism area of Inner Mongolia, dairy industry can create economic value for the development of tourism. In view of the importance of dairy products-the habitat of lactic acid bacteria, this study aims to reveal the composition of lactic acid bacteria in dairy products and isolate lactic acid bacteria resources. Firstly, we selected 60 traditional dairy product samples (from the pasture in scenic area of Inner Mongolia as the research objects. Based on the 16S rRNA gene sequence analysis, lactic acid bacteria in the samples were isolated and identified; Real-time quantitative polymerase chain reaction (q-PCR technology was applied to the comparative analysis on the population of dominant bacteria in samples. It was found that there were significant differences in the numbers of dominant bacteria in different dairy products. With the advantages of improving nutritional value and extending storage time of dairy products, lactic acid bacteria is contributive to the development of dairy industry, which further promotes the prosperity of economy and tourism. Therefore, it is of great importance to study the composition of lactic acid bacteria in dairy products.

This systematic review was conducted to explain the association between dairy products and colorectal cancer (CRC) risk in Middle Eastern and North African countries (MENA). The database consulted were PubMed, Clinical Trials, and Cochrane to extract the relevant studies published till the 31stof December 2016, using inclusion and exclusion criteria according to Prisma Protocol. The characteristics of these studies comprised the consumption of all types of dairy products in relation to CRC risk. Seven studies were included in this review. For dairy products overall, no significant association was found. Regarding modern dairy products, included studies found controversial results with OR = 9.88 (95% CI: 3.80-24.65) and OR a  = 0.14 (95% CI: 0.02-0.71). A positive association was reported between traditional dairy products and CRC risk, to OR = 18.66 (95% CI: 3.06-113.86) to OR = 24 (95% CI: 1.74-330.82) to ORa = 1.42 (95% CI: 0.62-3.25), p trend  = 0.03. Calcium was inversely associated with the CRC risk with OR a  = 0.08 (95% CI: 0.04-0.17). This is the first systematic review which illustrated the association between dairy consumption and CRC risk in MENA region. The results were inconsistent and not always homogeneous. Further specified studies may be warranted to address the questions about the association between CRC and dairy products in a specific context of MENA region.

Lactic acid bacteria (LAB) could synthesize cell envelope proteinase with weak activity, which primarily degrades casein. In addition to its crucial role in the rapid growth of LAB in milk, LAB proteinases are also of industrial importance due to their contribution to the formation of texture and flavor of many fermented dairy products. The proteolytic system, properties of proteinase, the degradation product of casein and its effect on the quality of fermented dairy products were reviewed in this manuscript.

The demand for low lactose dairy products is increasing and more different lactose free food is commercially available. The level of lactose in these products decreased during the last years and nowadays a concentration of lactose free". For the determination of the lactose concentrations in these dairy products a sensitive analysis method is needed. We developed a method for the determination of low concentrations of lactose in a wide range of dairy products. A simple sample preparation with dilution, centrifugation and ultrafiltration is efficient for the isolation of lactose from the sample matrix. In this paper, a new HPAEC-PAD analysis on a CarboPac PA100 column gives a good separation of lactose from the other saccharides. This separation in combination with the PAD detector yields a selective and sensitive method for the quantification at the desired concentrations of lactose in low lactose dairy products.

Caja, Gerardo; Castro-Costa, Andreia; Knight, Christopher H

Current trends in the global milk market and the recent abolition of milk quotas have accelerated the trend of the European dairy industry towards larger farm sizes and higher-yielding animals. Dairy cows remain in focus, but there is a growing interest in other dairy species, whose milk is often directed to traditional and protected designation of origin and gourmet dairy products. The challenge for dairy farms in general is to achieve the best possible standards of animal health and welfare, together with high lactational performance and minimal environmental impact. For larger farms, this may need to be done with a much lower ratio of husbandry staff to animals. Recent engineering advances and the decreasing cost of electronic technologies has allowed the development of 'sensing solutions' that automatically collect data, such as physiological parameters, production measures and behavioural traits. Such data can potentially help the decision making process, enabling early detection of health or wellbeing problems in individual animals and hence the application of appropriate corrective husbandry practices. This review focuses on new knowledge and emerging developments in welfare biomarkers (e.g. stress and metabolic diseases), activity-based welfare assessment (e.g. oestrus and lameness detection) and sensors of temperature and pH (e.g. calving alert and rumen function) and their combination and integration into 'smart' husbandry support systems that will ensure optimum wellbeing for dairy animals and thereby maximise farm profitability. Use of novel sensors combined with new technologies for information handling and communication are expected to produce dramatic changes in traditional dairy farming systems.

Listeria monocytogenes can cause listeriosis, a severe foodborne disease. In Brazil, despite very few reported cases of listeriosis, the pathogen has been repeatedly isolated from dairies. This has led the government to implement specific legislation to reduce the hazard. Here, we determined the incidence of L. monocytogenes in five dairies and retail products in the Southeast and Midwest regions of Brazil over eight months. Of 437 samples, three samples (0.7%) from retail and only one sample (0.2%) from the dairies were positive for L. monocytogenes. Thus, the contamination rate was significantly reduced as compared to previous studies. MultiLocus Sequence Typing (MLST) was used to determine if contamination was caused by new or persistent clones leading to the first MLST profile of L. monocytogenes from the Brazilian dairy industry. The processing environment isolate is of concern being a sequence-type (ST) 2, belonging to the lineage I responsible for the majority of listeriosis outbreaks. Also, ST3 and ST8 found in commercialized cheese have previously been reported in outbreaks. Despite the lower incidence, dairy products still pose a potential health risk and the occurrence of L. monocytogenes in dairies and retail products emphasize the need for continuous surveillance of this pathogen in the Brazilian dairy industry.

Full Text Available Background Listeria monocytogenes is a foodborne pathogen and a serious threat to the public health in the world. Consumption of traditional foods such as dairy and meat products can be a major reason for relative abundance and isolation of these bacteria. Objectives The purpose of this study was to determine the phenotypic and genotypic characteristics of L. monocytogenes strains isolated from dairy and meat products. Materials and Methods A total of 317 dairy products and meat-processed samples were collected. Antibiotic susceptibility test was performed on each sample by the disk diffusion method (Kirby Bauer. Five reference loci were used for typing of L. monocytogenes strains by MLVA (Multiple Locus VNTR Analysis Technique. Results A total of 24 L. monocytogenes isolates were collected from the dairy and meat products. Resistance of isolated L. monocytogenes strains to penicillin G were 54.54% (from dairy products and 46.15% (from processed meat. Genetic relatedness of isolates were assessed by MLVA. Out of 13 different types, type 2 with 6 strains and type 3 with 4 strains, were the most common types. Conclusions MLVA analysis showed that samples obtained from different sources could have similar genetic profile. As a result, administration of penicillin in patients with listeriosis (especially pregnant women and antibiotic susceptibility test are recommended. The fast and accurate methods such as MLVA for tracking of pollution sources of L. monocytogenes are recommended during outbreaks.

Dairy products are rich in nutrients that positively influence bone health and hence fracture risk, and have therefore been recommended and used for fracture prevention. To help decision makers to efficiently allocate scare resources, it is further important to assess the public health and economic impact of any health intervention. In recent years, several studies have been conducted to estimate the public health and/or economic impact of dairy products but no overview is currently available. This article aims therefore to summarize evidence and review articles that estimated the public health and/or economic impact of vitamin D-fortified dairy products for fracture prevention. A literature review was conducted using PubMed to identify original studies that assessed the public health and/or economic impact of dairy products (or of calcium/vitamin D supplementation) for fracture prevention up to January 15, 2017. Seven articles were identified. Different strategies were used by the authors to model the economic/public health impact of dairy products. The four studies assessing the public health impact of dairy products revealed a substantial benefit in terms of fracture prevented, life years, disability-adjusted life years and/or quality-adjusted life years gained. Studies assessing the cost-effectiveness revealed that the use of dairy products is generally cost-effective in the general population aged above 70 years, and from the age of 60 years in populations at high risk of fractures. This systematic review suggests that the use of dairy products could substantially reduce the burden of osteoporotic fractures and seem to be an economically beneficial strategy.

New Zealand Dairy Farming: Milking Our Environment for All Its Worth

Foote, Kyleisha J.; Joy, Michael K.; Death, Russell G.

2015-09-01

Over the past two decades there have been major increases in dairy production in New Zealand. This increase in intensity has required increased use of external inputs, in particular fertilizer, feed, and water. Intensified dairy farming thus incurs considerable environmental externalities: impacts that are not paid for directly by the dairy farmer. These externalities are left for the wider New Zealand populace to deal with, both economically and environmentally. This is counter-intuitive given the dairy industry itself relies on a `clean green' image to maximize returns. This is the first nationwide assessment of some of the environmental costs of the recent increase of dairy intensification in New Zealand. Significant costs arise from nitrate contamination of drinking water, nutrient pollution to lakes, soil compaction, and greenhouse gas emissions. At the higher end, the estimated cost of some environmental externalities surpasses the 2012 dairy export revenue of NZ11.6 billion and almost reaches the combined export revenue and dairy's contribution to Gross Domestic Product in 2010 of NZ5 billion. For the dairy industry to accurately report on its profitability and maintain its sustainable marketing label, these external costs should be reported. This assessment is in fact extremely conservative as many impacts have not been valued, thus, the total negative external impact of intensified dairying is probably grossly underestimated.

The recommended intake of vitamin D-fortified dairy products can substantially decrease the burden of osteoporotic fractures and seems an economically beneficial strategy in the general French population aged over 60 years. This study aims to assess the public health and economic impact of vitamin D-fortified dairy products in the general French population aged over 60 years. We estimated the lifetime health impacts expressed in number of fractures prevented, life years gained, and quality-adjusted life years (QALY) gained of the recommended intake of dairy products in the general French population over 60 years for 1 year (2015). A validated microsimulation model was used to simulate three age cohorts for both women and men (60-69, 70-79, and >80 years). The incremental cost per QALY gained of vitamin D-fortified dairy products compared to the absence of appropriate intake was estimated in different populations, assuming the cost of two dairy products per day in base case. The total lifetime number of fractures decreased by 64,932 for the recommended intake of dairy products in the general population over 60 years, of which 46,472 and 18,460 occurred in women and men, respectively. In particular, 15,087 and 4413 hip fractures could be prevented in women and men. Vitamin D-fortified dairy products also resulted in 32,569 QALYs and 29,169 life years gained. The cost per QALY gained of appropriate dairy intake was estimated at €58,244 and fall below a threshold of €30,000 per QALY gained in women over 70 years and in men over 80 years. Vitamin D-fortified dairy products have the potential to substantially reduce the burden of osteoporotic fractures in France and seem an economically beneficial strategy, especially in the general population aged above 70 years.

Full Text Available The angiotensin-converting enzyme (ACE regulates the levels of blood pressure through generation of angiotensin-II from angiotensin-I. It is of great importance to have a reliable and yet simple method for a quantitative determination ACE inhibitory peptides in whey of milk products. A rapid, simple, sensitive and accurate spectrophotometric kinetic method has been developed for determination of ACE inhibitory peptides, using competitive inhibition. Samples of dairy product from the market were used for the determination of ACE inhibitory peptides in whey. Holmquist’s kinetic method was used for determining ACE inhibitory activity in blood serum and Ronca-Testoni method was used for the determination of ACE inhibitory activity in whey. Enzymatic inhibition activity was determined using 0.8 mmol/L FAPGG (N-[3-(Furyl –Acryloyl]-L-Phenylalanyl Glycyl Glycyne as the substrate in 50 mmol/L Tris buffer at pH 8.2 at 37°C and a standard serum containing ACE. First, a solution of whey was mixed in a 1 to 10 ratio with serum (elevation containing high ACE activity. The enzymatic activity was determined by monitoring the decrease in absorbance at 340 nm as result of hydrolysis of the substrate. The concentration of ACE inhibitory peptides was determined from a standard curve of inhibitor concentration versus percent of ACE inhibition. The study suggests that the method possesses good reproducibility and accuracy. The linear range enabled determination of high enzymatic activity of ACE and all ACE inhibitory peptides from dairy products act as competitive inhibitors.

In this study, the antibiotic resistance (AR) of lactic acid bacteria (LAB) isolated from traditional Turkish fermented dairy products was investigated. Yogurt, white cheese, tulum cheese, cokelek, camız cream and kefir as dairy products were collected from various supermarkets. Lactic acid bacteria such as Lactobacillus spp., Streptococcus spp., Bifidobacterium spp., and Enterecoccus spp. were isolated from these dairy products. Lactobacillus spp. were resistant to vancomycin (58%), erythromycin (10.8%), tetracycline (4.3%), gentamicin (28%), and ciprofloxacin (26%). Streptococcus spp. were resistant to vancomycin (40%), erythromycin (10%), chloramphenicol (10%), gentamicin (20%), and ciprofloxacin (30%). Bifidobacterium spp. were resistant to vancomycin (60%), E 15 (6.6%), gentamicin (20%), and ciprofloxacin (33%). Enterococcus spp. were resistant to vancomycin (100%), erythromycin (100%), rifampin (100%), and ciprofloxacin (100%). As a result, LAB islated from dairy products in this study showed mostly resistance to vancomycin.

Dairy propionibacteria, including Propionibacterium freudenreichii , display promising probiotic properties, including immunomodulation. These properties are highly strain-dependent and rarely studied in a fermented dairy product. We screened 10 strains, grown in a newly developed fermented milk ultrafiltrate, for immunomodulatory properties in vitro. The most anti-inflammatory strain, P. freudenreichii BIA129, was further tested on piglets. P. freudenreichii -fermented product improved food intake and growth of piglets. Colonic mucosa explants of treated pigs secreted less interleukin 8 (-25%, P dairy propionibacteria-fermented products, which are promising for the prevention or healing of inflammatory bowel diseases.

Full Text Available Background: Dairy products and alternatives can contribute to overall good health including positive body composition and decreased adiposity; however, these foods are grossly underconsumed by youth, and worldwide, almost 25% of children are overweight or obese. Objective: The study investigated the barriers and facilitators toward dairy consumption by Grade 7 youth. Methods: Thirty 50-minute, audio-recorded focus groups were conducted with 134 students in eight Grade 7 classes across 5 elementary schools. Focus groups were led by trained facilitators in the elementary schools and participants were separated based on dairy consumption and gender. Recorded data were transcribed and thematically analyzed using qualitative analysis software to identify themes related to barriers and facilitators to dairy product intake by each gender. Results: Factors considered important by males and females across different levels of habitual intake include personal knowledge about dairy products and misconceptions regarding dairy foods and their associated health benefits; food characteristics, including taste; personal behaviors such as habits or routines including dairy products; social environments including parental and peer influence; physical environments factors such as availability and skipping meals; and the convenience of dairy products. Interestingly, only males noted sports as a positive influence for dairy product intake. Also, there were differences in the way males and females perceived dining out as affecting their dairy intake. Conclusion: Results suggest several potential factors that nutrition education interventions aiming to increase dairy consumption could target.

Full Text Available Dairy farm wastewaters are potential resources for production of microalgae biofuels. A study was conducted to evaluate the capability of production of biodiesel from consortium of native microalgae culture in dairy farm treated wastewater. Native algal strains were isolated from dairy farm wastewaters collection tank (untreated wastewater as well as from holding tank (treated wastewater. The consortium members were selected on the basis of fluorescence response after treating with Nile red reagent. Preliminary studies of two commercial and consortium of ten native strains of algae showed good growth in wastewaters. A consortium of native strains was found capable to remove more than 98% nutrients from treated wastewater. The biomass production and lipid content of consortium cultivated in treated wastewater were 153.54 t ha−1 year−1 and 16.89%, respectively. 72.70% of algal lipid obtained from consortium could be converted into biodiesel.

Full Text Available Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, mainly through the process of replacing or including beneficial bacteria in the gastrointestinal tract. Fermented dairy foods such as yogurt, fermented milk and cheese are the major vehicle in delivering probiotics, and probiotic delivery have been traditionally associated with these fermented dairy foods. Additionally, many other non-dairy probiotic products and non-food form such as capsules, pills and tablets are also available and some of these non-food forms are highly popular among the consumers. Certain non-dairy probiotic foods, especially beverages that are non-fermented products, can also play an important role in probiotic delivery. There is an increasing demand for non-dairy probiotic foods (both fermented and non-fermented including fruit and vegetable juices, soy and certain cereal products due to vegetarianism, lactose intolerance and dairy allergies, as well as interest in low cholesterol foods. In this context, this review mainly focus on the different types of probiotic food products including beverages with special reference to their viability followed by a brief account on the applicability of using fermented and non-fermented beverage products in probiotic delivery.

2016-01-01

Full Text Available This paper reports incentives, costs, difficulties and benefits of food safety management systems implementation in the Serbian dairy industry. The survey involved 27 food business operators with the national milk and dairy market share of 65 %. Almost two thirds of the assessed dairy producers (70.4 % claimed that they had a fully operational and certified HACCP system in place, while 29.6 % implemented HACCP, but had no third party certification. ISO 22000 was implemented and certified in 29.6 % of the companies, while only 11.1 % had implemented and certified IFS standard. The most important incentive for implementing food safety management systems for Serbian dairy producers was to increase and improve safety and quality of dairy products. The cost of product investigation/analysis and hiring external consultants were related to the initial set-up of food safety management system with the greatest importance. Serbian dairy industry was not greatly concerned by the financial side of implementing food safety management systems due to the fact that majority of prerequisite programmes were in place and regularly used by almost 100 % of the producers surveyed. The presence of competency gap between the generic knowledge for manufacturing food products and the knowledge necessary to develop and implement food safety management systems was confirmed, despite the fact that 58.8 % of Serbian dairy managers had university level of education. Our study brings about the innovation emphasizing the attitudes and the motivation of the food production staff as the most important barrier for the development and implementation of HACCP. The most important identified benefit was increased safety of dairy products with the mean rank scores of 6.85. The increased customer confidence and working discipline of staff employed in food processing were also found as important benefits of implementing/operating HACCP. The study shows that the level of HACCP

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.

The functional food sector has shown tremendous growth in recent years with the application of probiotic bacteria as "food additives". The utilization of probiotic bacteria in food presents many challenges related to their growth, survival, viability, stability and functionality in food processing, storage and consumption as well as changes of sensory characteristics of probiotic foods. Although dairy foods are currently the most common food carrier to deliver probiotics, an increasing number of non-dairy food matrices exhibit potential for delivery of probiotics. This review provides more recent insight into the emergence of non-dairy probiotics products, the interactions between probiotics and different food matrices and the challenges in developing such products. Some of the technical issues are also reviewed and discussed. These issues include the efficacy of probiotic bacteria in non-chilled, low pH or high water activity foods; the potential loss of bacterial viability, additionally unwanted fermentation and changes of the sensory characteristics of food products which may result in poor microbiological quality and low acceptability to consumers.

There is scepticism about health effects of dairy products in the public, which is reflected in an increasing intake of plant-based drinks, for example, from soy, rice, almond, or oat. This review aimed to assess the scientific evidence mainly from meta-analyses of observational studies and randomised controlled trials, on dairy intake and risk of obesity, type 2 diabetes, cardiovascular disease, osteoporosis, cancer, and all-cause mortality. The most recent evidence suggested that intake of milk and dairy products was associated with reduced risk of childhood obesity. In adults, intake of dairy products was shown to improve body composition and facilitate weight loss during energy restriction. In addition, intake of milk and dairy products was associated with a neutral or reduced risk of type 2 diabetes and a reduced risk of cardiovascular disease, particularly stroke. Furthermore, the evidence suggested a beneficial effect of milk and dairy intake on bone mineral density but no association with risk of bone fracture. Among cancers, milk and dairy intake was inversely associated with colorectal cancer, bladder cancer, gastric cancer, and breast cancer, and not associated with risk of pancreatic cancer, ovarian cancer, or lung cancer, while the evidence for prostate cancer risk was inconsistent. Finally, consumption of milk and dairy products was not associated with all-cause mortality. Calcium-fortified plant-based drinks have been included as an alternative to dairy products in the nutrition recommendations in several countries. However, nutritionally, cow's milk and plant-based drinks are completely different foods, and an evidence-based conclusion on the health value of the plant-based drinks requires more studies in humans. The totality of available scientific evidence supports that intake of milk and dairy products contribute to meet nutrient recommendations, and may protect against the most prevalent chronic diseases, whereas very few adverse effects have

Full Text Available Since 1980, livestock husbandry has steadily increased in the south of Chad, particularly because of transhumant herd moves from the center to the south of the country. Supplying cities and villages with dairy products is an important trade for the breeders. This trade was the foundation for pastoral breeders to settle down around the city of Moundu. Can such a livestock system respond in a sustainable way to the quickly growing demand of the population? Does it change as a result of integrating the market? Suburban dairy producers, dairy processors, salespersons and consumers were surveyed to better understand the organization of this subsector. Results show that the traditional dairy product trade is dynamic. More than 5000 liters originating from suburban Fulani settlements reach city markets every day. The livestock system is also adapting itself well to the new trade environment, while keeping its intrinsic mobility, even on short distances. In addition, urban dairy processors (cheesemakers and dairy bars boost this subsector. Finally, there is not much competition with imports due to the area being enclosed and consumers’ preference for traditional products. However, Fulani pastoralist settlements generate some conflicts on land use. This study shows the need to initiate more talks between livestock breeders and cotton producers, to reorganize the cotton oilseed cake market, and to develop small dairy-processing units.

Full Text Available The research has investigated the adoption of administration practices in the set of costs in dairy product industries in the Southwest Region in Parana State, as well as, the contingency factors which has influenced the system in the management control at these companies. The explore research was developed through a study on data in quantitative approach in forty- three dairies. From these, just twenty-three produce milk and the other twenty cheese and its derivatives. According to the study these companies are concerned on how to check their costs on production. However, just the dairies which produce cheese and its derivatives are managing costs based on data in a planning and control process. The way used to determine the costs is based on the method of market value. These organizations stand out by the development of control systems of computerized costs where the aims are related to right identification of the costs and the prices for sale, as well. The main outside elements which have affected the organizations are the market needs and the goods availability. In relation to the model  of the manage control in these organizations, it was  checked that these are different from the others in the strategies structure, complexity in the production process, level of computerization and the aims of the use. It was concluded that the administration practices in those researched dairies are influenced by contingency factors.

Full Text Available This paper presents the importance of the crop structure as a tool to maximize efficiency in the conceiving of the green forage supply scheme in a dairy farm. Several apects are necessary to consider for proper green forage utilization by the cattle, as follows: climatic conditions, proper field operations for each crop, optimal harvest date, and farm technical and economical resources. With a high degree of succulence, green forage and derived products (silage, haylage, present addvantages as compared to hay, having superior indices of nutritive value and palatability. A green forage supply scheme was applied on an area of 188 ha taking into account dairy cattle biological traits. Crop structure was as follows: forage maize, Sudan grass, Italian ryegrass, new lucern and old lucerne, and orchardgrass. Insuring the required superior green forage for the dairy cattle according to forage rations, represents one of the main techniques to maximize milk production and to minimize milk production cost.

Full Text Available Dairy product intake and a person’s genetic background have been reported to be associated with the risk of type 2 diabetes (T2D. The objective of this study was to examine the interaction between dairy products and genes related to T2D on glucose-insulin homeostasis parameters. A validated food frequency questionnaire, fasting blood samples, and glucokinase (GCK genotypes were analyzed in 210 healthy participants. An interaction between rs1799884 in GCK and dairy intake on the homeostasis model assessment of insulin resistance was identified. Secondly, human hepatocellular carcinoma cells (HepG2 were grown in a high-glucose medium and incubated with either 1-dairy proteins: whey, caseins, and a mixture of whey and casein; and 2-four amino acids (AA or mixtures of AA. The expression of GCK-related genes insulin receptor substrate-1 (IRS-1 and fatty acid synthase (FASN was increased with whey protein isolate or hydrolysate. Individually, leucine increased IRS-1 expression, whereas isoleucine and valine decreased FASN expression. A branched-chain AA mixture decreased IRS-1 and FASN expression. In conclusion, carriers of the A allele for rs1799884 in the GCK gene may benefit from a higher intake of dairy products to maintain optimal insulin sensitivity. Moreover, the results show that whey proteins affect the expression of genes related to glucose metabolism.

DAIRY INDUSTRY: ALTERNATIVES TO RECOVERY WHEY AS A MEANS OF ENVIRONMENTAL MANAGEMENT

Directory of Open Access Journals (Sweden)

Liliane Marquardt

2012-01-01

Full Text Available Small and medium industries of dairy products in Brazil are facing serious problems of competition for the consumer market due to factors such as small scale production, lack of standardization of products and processes, deficiencies in effective control of quality, difficult to define niche markets and different levels of technology, although they are generating jobs and income. In addition to these factors, it appears that the control of environmental impacts caused by these industries, given the current environmental legislation, has forced a change of attitude on the part of entrepreneurs, in order to control pollution, despite the shortcomings often perceived in infrastructure linked to industrialization, such as high energy and water. The treatment and disposal of effluents and solid waste disposal, which are critical in industrial processes, are often overlooked in small and medium industries, generating significant environmental impacts. Among the main environmental impacts generated by the dairy industry stands to generate significant amounts of wastewater with high organic load. In this sense, the main objective of this study was a literature survey concerning the main factors of environmental impact of small and medium industries in the dairy sector, aiming to propose alternative environmental management that favors the minimization of the factors generating these impacts.

Glycerol from biodiesel production: the new corn for dairy cattle

Directory of Open Access Journals (Sweden)

Shawn S Donkin

Full Text Available Glycerol, also known as glycerin, is a colorless, odorless, hygroscopic, and sweet-tasting viscous liquid. It is a sugar alcohol with high solubility index in water and has a wide range of applications in the food, pharmaceutical, and cosmetic industries. The use of glycerol in diets for dairy cattle is not novel; however, this interest has been renewed due to the increased availability and favorable pricing of glycerol as a consequence of recent growth in the biofuels industry. Experimental evidence supports the use of glycerol as a transition cow therapy but feeding rates are low, ranging from 5 to 8 % of the diet DM. There is a paucity of research that examines the use of glycerol as a macro-ingredient in rations for lactating dairy cows. Most reports indicate a lack of effect of addition of glycerol to the diet when it replaces corn or corn starch. Recent feeding experiments with lactating dairy cows indicate replacing corn with glycerol to a level of 15% of the ration DM does not adversely effect milk production or composition. Milk production was 37.0, 36.9, 37.3, 36.4 ± 0.6 kg/d and feed intake was 24.0, 24.5, 24.6, 24.1 ± 0.5 kg/d for 0, 5, 10 and 15% glycerol treatments respectively and did not differ (P > 0.05 except for a modest reduction in feed intake during the first 7 days for the 15% glycerol treatment. Glycerol fed to dairy cattle is fermented to volatile fatty acids in the rumen and early reports indicated that glycerol is almost entirely fermented to propionate. In vitro data indicates glycerol fermentation increases the production of propionate and butyrate at the expense of acetate. Rumen microbes appear to adapt to glycerol feeding and consequently, cows fed glycerol also require an adaptation period to glycerol inclusion. Debate exists regarding the fate of glycerol in the rumen and although most reports suggest that glycerol is largely fermented in the rumen, the extent of rumen digestion may depend on level of

The objective of this systematic review was to determine if dairy product consumption is detrimental, neutral, or beneficial to cardiovascular health and if the recommendation to consume reduced-fat as opposed to regular-fat dairy is evidence-based. A systematic review of meta-analyses of prospective population studies associating dairy consumption with cardiovascular disease (CVD), coronary artery disease (CAD), stroke, hypertension, metabolic syndrome (MetS), and type 2 diabetes (T2D) was conducted on the basis of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Quality of evidence was rated by using the Grading of Recommendations Assessment, Development, and Evaluation scale. High-quality evidence supports favorable associations between total dairy intake and hypertension risk and between low-fat dairy and yogurt intake and the risk of T2D. Moderate-quality evidence suggests favorable associations between intakes of total dairy, low-fat dairy, cheese, and fermented dairy and the risk of stroke; intakes of low-fat dairy and milk and the risk of hypertension; total dairy and milk consumption and the risk of MetS; and total dairy and cheese and the risk of T2D. High- to moderate-quality evidence supports neutral associations between the consumption of total dairy, cheese, and yogurt and CVD risk; the consumption of any form of dairy, except for fermented, and CAD risk; the consumption of regular- and high-fat dairy, milk, and yogurt and stroke risk; the consumption of regular- and high-fat dairy, cheese, yogurt, and fermented dairy and hypertension risk; and the consumption of regular- and high-fat dairy, milk, and fermented dairy and T2D risk. Data from this systematic review indicate that the consumption of various forms of dairy products shows either favorable or neutral associations with cardiovascular-related clinical outcomes. The review also emphasizes that further research is urgently needed to compare the impact of

How can dairies maximize their profits and properly remunerate their dairy farmers?

Full Text Available ABSTRACT The current pricing process of raw milk in Brazil discourages producers from improving milk composition, which affects both yield and quality of dairy products. Furthermore, small and medium-sized dairies face great difficulties when it comes to planning production. Thus, a linear programming model was developed to price the raw milk and determine the optimal mix (combination of quantities of dairy products that maximizes total contribution margin (TCM under daily scenarios of high (January and low (July raw milk supplies (summer and winter, respectively by comparing optimal solutions with actual results. The TCM of optimal and actual mixes were higher in January due to the greater availability of raw material. Packaging was a limiting factor in the production of cheese in optimal mixes. The relationship between unit contribution margin (UCM and the required amount of raw materials per product unit and resource availability is crucial to defining the mix of dairy products and TCM of the dairy. Casein and raw milk volume showed shadow prices. Under both scenarios, the calculated prices of raw milk were higher than the prices charged by the dairy and were higher in January. The proposed model remunerates the producers based on the quantity and quality of raw milk. The dairy can maximize its TCM by better planning its mix of products with the use of linear programming.

Influence of Amino Acids in Dairy Products on Glucose Homeostasis: The Clinical Evidence.

Science.gov (United States)

Chartrand, Dominic; Da Silva, Marine S; Julien, Pierre; Rudkowska, Iwona

2017-06-01

Dairy products have been hypothesized to protect against type 2 diabetes because of their high content of whey proteins, rich in branched-chain amino acids (BCAAs) - leucine, isoleucine and valine - and lysine, which may decrease postprandial glucose responses and stimulate insulin secretion. Paradoxically, epidemiologic studies also show that higher levels of plasma BCAAs have been linked to insulin resistance and type 2 diabetes. Therefore, the objective was to review the recent clinical evidence concerning the intake of amino acids found in dairy proteins so as to determine their impact on glucose homeostasis in healthy persons and in those with prediabetes and type 2 diabetes. Clinical studies have reported that the major dairy amino acids, namely, leucine, isoleucine, glutamine, phenylalanine, proline and lysine, have beneficial effects on glucose homeostasis. Yet the reported doses of amino acids investigated are too elevated to be reached through adequate dairy product intake. The minor dairy amino acids, arginine and glycine, may improve glucose homeostasis by improving other risk factors for type 2 diabetes. Further, the combination of amino acids may also improve glucose-related outcomes, suggesting additive or synergistic effects. Nevertheless, additional long-term studies in individuals with prediabetes and type 2 diabetes are needed to ascertain the benefits for glucose homeostasis of amino acids found in dairy foods.

Understanding consumers' motives for selecting calorie-reduced dairy products are important to provide targeted communication to different consumer segments. The aim of this study was to identify motives for consumption of calorie-reduced dairy products among young consumers, and to identify how these consumers perceive the healthiness of such products compared to other food products. Consumers, aged 18-30 years, from Norway (n=118), Denmark (n=125), and California (n=127) participated in this cross-cultural study. The respondents sorted 24 statements referring to motives for choosing calorie-reduced yoghurt and cheese. The study also assessed the aspect of perceived healthiness of these products in comparison with a selection of other food products using a two-step ranking procedure. The data were analysed using chi-square analysis, Friedman's test and Principal Component Analysis (PCA). The results show that fat content, healthiness and taste were the most important motivators for choice of the calorie-reduced dairy products. In all three countries salmon was perceived as the healthiest among the products presented. The calorie-reduced dairy products were ranked as relatively healthy, with yoghurt ranked as healthier than cheese. Although cross-cultural differences existed in motives for choice and perceived healthiness of the products, the similarities between the countries were evident in this study.

The efforts to improve and optimize productivity of dairy cows require sufficient availability of nutrients, especially high energy in the early period of lactation. Increasing energy intake in dairy cows can be conducted by increasing the density of energy. The research aimed to evaluate dietary protected feed supplement on milk production and quality, including: fat, protein, and lactose content of Friesian Holstein dairy cow milk. Protected feed supplement was produced from sardine fish oil, through saponification and microencapsulation protection methods. The experiment consists of two treatments i.e. P0: basal diet (control) and P1: basal diet + 3 % protected feed supplement. Each treatment was repeated 15 times. Data were analyzed by independent samples t-test analysis. Results showed that supplementation of protected sardine fish oil had no effect on lactose content, but increased milk yield production (pmilk fat content (p<0.05), and protein content (p<0.05).

We evaluated the protective effects of fermented dairy products (FDPs) in an infection model, using the mouse pathogen Citrobacter rodentium (CR). Treatment of mice with FDP formulas A, B, and C or a control product did not affect CR colonization, organ specificity, or attaching and effacing lesion formation. Fermented dairy product A (FDP-A), but neither the supernatant from FDP-A nor β-irradiated (IR) FDP-A, caused a significant reduction in colonic crypt hyperplasia and CR-associated pathology. Profiling the gut microbiota revealed that IR-FDP-A promoted higher levels of phylotypes belonging to Alcaligenaceae and a decrease in Lachnospiraceae (Ruminococcus) during CR infection. Conversely, FDP-A prevented a decrease in Ruminococcus and increased Turicibacteraceae (Turicibacter). Importantly, loss of Ruminococcus and Turicibacter has been associated with susceptibility to dextran sodium sulfate-induced colitis. Our results demonstrate that viable bacteria in FDP-A reduced CR-induced colonic crypt hyperplasia and prevented the loss of key bacterial genera that may contribute to disease pathology. © The Author 2014.

From a clinical perspective, it is essential to know the microbial safety of fermented dairy products. Doogh and kashk are fermented dairies. These products are used by millions of people but their microbial qualities are unknown. Shiga toxin producing Escherichia coli (STEC) is one of the most commonly detected pathogens in the cases of food poisoning and food-borne illnesses. The present investigation was carried out in order to study the molecular characterization and antimicrobial resistance properties of STEC strains isolated from fermented dairy products. Six hundred fermented dairy samples were collected and immediately transferred to the laboratory. All samples were cultured immediately and those that were E. coli-positive were analyzed for the presence of O157 , O26, O103, O111, O145, O45, O91, O113, O121 and O128 STEC serogroups, tetA, tetB, blaSHV, CITM, cmlA, cat1, aadA1, dfrA1, qnr, aac (3)-IV, sul1 and ereA antibiotic resistance genes and stx1, stx2, eaeA, ehly, cnf1, cnf2, iutA, cdtB, papA, traT, sfaS and fyuA virulence factors using PCR. Antimicrobial susceptibility testing was performed also using disk diffusion methodology with Mueller-Hinton agar. Fifty out of 600 (8.33%) dairy samples harbored E. coli. In addition, yoghurt was the most commonly contaminated dairy. O157 (26%) and O26 (12%) were the most commonly detected serogroups. A significant difference was found between the frequency of Attaching and Effacing E. coli and Enterohaemorrhagic E. coli (P Fermented dairy products can easily become contaminated by antibiotic resistant STEC strains. Our findings should raise awareness about antibiotic resistance in Iran. Clinicians should exercise caution when prescribing antibiotics, especially in veterinary treatments.

Demographic and management data about organic dairies have been reported previously, but the current study is the first needs assessment of research and educational priorities of organic dairy farmers in the northeastern United States based directly upon their input. Our objectives were to (1) develop an initial understanding of the emerging research and educational needs of organic dairy farmers in the northeastern United States via focus group interviews, and (2) prioritize the needs identified by the focus groups with a broader population of organic dairy farmers via survey methods. Focus group interviews determined the questions used for the survey questionnaire distributed to 1,200 members of the Northeast Organic Dairy Producers Alliance. The members were asked about demographic information, but more importantly, challenges concerning business management and marketing, organic certification, and animal nutrition, health, and reproduction. The results (183 respondents, 15% response rate) were parsed by region (New England farms compared with New York and Pennsylvania farms), herd size (i.e., 12 to 37, 38 to 59, and >60 cows), and years of organic certification (organic treatments for mastitis (92% respondents), growing forages for organic production (84%), and developing value-added products (84%). Farms with organic certification were concerned with level of knowledge and experience of local certifiers, whereas organic producers with ≥ 4 yr of organic certification were more interested in field testing of new organic products. Opportunities for educational programs included learning about direct marketing possibilities (76% respondents) and providing training to regional veterinarians interested in organic remedies (91%). In conclusion, the information obtained from the current needs assessment provides a foundation for future research proposals and educational outreach programs, germane to stakeholder needs, which could benefit the organic dairy industry

The objective of this systematic review was to determine if dairy product consumption is detrimental, neutral, or beneficial to cardiovascular health and if the recommendation to consume reduced-fat as opposed to regular-fat dairy is evidence-based. A systematic review of meta-analyses of prospective population studies associating dairy consumption with cardiovascular disease (CVD), coronary artery disease (CAD), stroke, hypertension, metabolic syndrome (MetS), and type 2 diabetes (T2D) was conducted on the basis of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Quality of evidence was rated by using the Grading of Recommendations Assessment, Development, and Evaluation scale. High-quality evidence supports favorable associations between total dairy intake and hypertension risk and between low-fat dairy and yogurt intake and the risk of T2D. Moderate-quality evidence suggests favorable associations between intakes of total dairy, low-fat dairy, cheese, and fermented dairy and the risk of stroke; intakes of low-fat dairy and milk and the risk of hypertension; total dairy and milk consumption and the risk of MetS; and total dairy and cheese and the risk of T2D. High- to moderate-quality evidence supports neutral associations between the consumption of total dairy, cheese, and yogurt and CVD risk; the consumption of any form of dairy, except for fermented, and CAD risk; the consumption of regular- and high-fat dairy, milk, and yogurt and stroke risk; the consumption of regular- and high-fat dairy, cheese, yogurt, and fermented dairy and hypertension risk; and the consumption of regular- and high-fat dairy, milk, and fermented dairy and T2D risk. Data from this systematic review indicate that the consumption of various forms of dairy products shows either favorable or neutral associations with cardiovascular-related clinical outcomes. The review also emphasizes that further research is urgently needed to compare the impact of

As part of an overall composition study of Finnish foods, the carotenoid and retinoid content of 20 dairy product samples and eggs were determined by HPLC. The total beta-carotene (all-trans beta-carotene plus 15-cis beta-carotene) was quantitated for dairy products. For egg and egg yolk, lutein content was also determined. Only traces of lycopene, cryptoxanthin, and alpha-carotene were present. All-trans retinol and 13-cis retinol were the major retinoids in dairy products. Small amounts of 9-cis, 11-cis, and 9,11-cis retinols were found. High values of both retinol and beta-carotene were found in full fat cheeses and whipping cream: from 179.0 (cheese, Edam-type) to 318.7 micrograms/100 g (whipping cream) and from 86.7 (cheese, Edam-type) to 186.5 micrograms/100 g (whipping cream) for all-trans retinol and total beta-carotene, respectively. The retinol content averaged 16.3, 32.6, and 52.2 and that of beta-carotene 9.6, 16.7, and 3.0 micrograms/100 g in milk (1.9% fat), milk (3.9% fat), and human milk, respectively. The major pigment in eggs and egg yolk was lutein, 619.5 micrograms/100 g in eggs and 1575.8 micrograms/100 g in egg yolk. According to this study, at the present level of consumption in Finland, milk, milk products (excluding butter), and eggs result in a daily intake of about 350 retinol equivalents, and consequently, are a major source of vitamin A.

Therefore, we examined cross-sectional associations of a broad variety of dairy subgroups with pre-diabetes and newly diagnosed type 2 diabetes (ND-T2DM) among Dutch adults. In total, 112 086 adults without diabetes completed a semi-quantitative FFQ and donated blood. Pre-diabetes was defined as fasting plasma glucose (FPG) between 5·6 and 6·9 mmol/l or HbA1c% of 5·7-6·4 %. ND-T2DM was defined as FPG ≥7·0 mmol/l or HbA1c ≥6·5 %. Logistic regression analyses were conducted by 100 g or serving increase and dairy tertiles (T1ref), while adjusting for demographic, lifestyle and dietary covariates. Median dairy product intake was 324 (interquartile range 227) g/d; 25 549 (23 %) participants had pre-diabetes; and 1305 (1 %) had ND-T2DM. After full adjustment, inverse associations were observed of skimmed dairy (OR100 g 0·98; 95 % CI 0·97, 1·00), fermented dairy (OR100 g 0·98; 95 % CI 0·97, 0·99) and buttermilk (OR150 g 0·97; 95 % CI 0·94, 1·00) with pre-diabetes. Positive associations were observed for full-fat dairy (OR100 g 1·003; 95 % CI 1·01, 1·06), non-fermented dairy products (OR100 g 1·01; 95 % CI 1·00, 1·02) and custard (ORserving/150 g 1·13; 95 % CI 1·03, 1·24) with pre-diabetes. Moreover, full-fat dairy products (ORT3 1·16; 95 % CI 0·99, 1·35), non-fermented dairy products (OR100 g 1·05; 95 % CI 1·01, 1·09) and milk (ORserving/150 g 1·08; 95 % CI 1·02, 1·15) were positively associated with ND-T2DM. In conclusion, our data showed inverse associations of skimmed and fermented dairy products with pre-diabetes. Positive associations were observed for full-fat and non-fermented dairy products with pre-diabetes and ND-T2DM.

Osteoporosis has become a major health concern, carrying a substantial burden in terms of health outcomes and costs. We constructed a model to quantify the potential effect of an additional intake of calcium from dairy foods on the risk of osteoporotic fracture, taking a health economics perspective. This study seeks, first, to estimate the impact of an increased dairy consumption on reducing the burden of osteoporosis in terms of health outcomes and costs, and, second, to contribute to a generic methodology for assessing the health-economic outcomes of food products. We constructed a model that generated the number of hip fractures that potentially can be prevented with dairy foods intakes, and then calculated costs avoided, considering the healthcare costs of hip fractures and the costs of additional dairy foods, as well as the number of disability-adjusted life years (DALYs) lost due to hip fractures associated with low nutritional calcium intake. Separate analyses were done for The Netherlands, France, and Sweden, three countries with different levels of dairy products consumption. The number of hip fractures that may potentially be prevented each year with additional dairy products was highest in France (2,023), followed by Sweden (455) and The Netherlands (132). The yearly number of DALYs lost was 6,263 for France, 1,246 for Sweden, and 374 for The Netherlands. The corresponding total costs that might potentially be avoided are about 129 million, 34 million, and 6 million Euros, in these countries, respectively. This study quantified the potential nutrition economic impact of increased dairy consumption on osteoporotic fractures, building connections between the fields of nutrition and health economics. Future research should further collect longitudinal population data for documenting the net benefits of increasing dairy consumption on bone health and on the related utilization of healthcare resources.

Brazil started to export dairy products in the early 2000s and since then has slowly consolidated its position in the world dairy market. To ensure the position in the international market by improving the quality of milk produced in the country, the government created a national program and a network of laboratories for milk quality. The Normative Instruction 51 (Instrucao Normativa 51-IN51) was introduced within the national program establishing parameters for milk quality and safety. In spite of not being included in the IN51, chemical elements are under thorough discussion as quality parameters for their nutritional and toxicological relevance. This work aimed at evaluating the quality of milk from one of the major dairy regions in Brazil, located in the state of Rio Grande do Sul, by the determination of chemical elements, comparing the results with those previously obtained for milk samples from the main dairy region of the country, in the state of Minas Gerais. Samples were collected from cooling tanks in nineteen dairy farms. After freeze drying, chemical elements were determined by instrumental neutron activation analysis (INAA) and inductively coupled plasma mass spectrometry (ICP-MS). For ten out of sixteen chemical elements determined, there were significant differences between samples from both producing regions (p < 0.01). (author)

Junge, Martin; Severgnini, Battista; Sørensen, Anders

The role of product and marketing innovation for productivity growth is addressed using survey and register data for the Danish economy. It is argued that marketing and product innovation are complementary inputs and that innovation activities are skill-intensive. It is found that product...... and marketing innovation in skill-intensive firms results in significantly faster productivity growth than in unskilled-intensive firms that introduce this combination of innovation activities. More precisely, an increase in the share of educated workers of one percentage point, increases productivity growth...... by around 0.1 percentage point in firms with product and marketing innovation. In addition, it is found that firms that engage in product innovation but not in marketing innovation or the other way around do not demonstrate a growth effect from their innovation activities. It is also found that product...

Dairy propionibacteria display probiotic properties which require high populations of live and metabolically active propionibacteria in the colon. In this context, the probiotic vector determines probiotic efficiency. Fermented dairy products protect propionibacteria against digestive stresses and generally contain a complex mixture of lactic and propionic acid bacteria. This does not allow the identification of dairy propionibacteria specific beneficial effects. The aim of this study was to develop a dairy product exclusively fermented by dairy propionibacteria. As they grow poorly in milk, we determined their nutritional requirements concerning carbon and nitrogen by supplementing milk ultrafiltrate (UF) with different concentrations of lactate and casein hydrolysate. Milk or UF supplemented with 50 mM lactate and 5 g L(-1) casein hydrolysate allowed growth of all dairy propionibacteria studied. In these new fermented dairy products, dairy propionibacteria remained viable and stress-tolerant in vitro during minimum 15 days at 4 °C. The efficiency of milk fermented by the most tolerant Propionibacterium freudenreichii strain was evaluated in piglets. Viability and SCFA content in the colon evidenced survival and metabolic activity of P. freudenreichii. This work results in the design of a new food grade vector, which will allow preclinical and clinical trials. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available This study aimed to assess the occurrence and diversity of mold species in raw milk and its products along with the identification of potential contamination sources. For this reason, a total of 260 samples consisting of 80 raw milk, 100 dairy products (i.e., pasteurized milk, yoghurt, cheese and buttermilk and 80 environmental (i.e. ingredients, packaging materials, surface of processing equipments and air specimens were collected. Using culture assay and microscopic observation, the occurrence as well as the diversity of mold species was investigated. According to the results, 82.3% of the samples were identified as positive for mold contamination. The percentage of mold contamination for raw milk was estimated as 97.5%. In the case of pasteurized milk, yoghurt, buttermilk, cheese and environmental samples, it was determined as 52%, 76%, 52%, 56% and 96.25%, respectively. Mold diversity among various samples consisted of Aspergillus, Geotrichum, Penicillium, Mucor, Alternaria, Rhizopus, Stemphylium, Cladosporium, and Fusarium. Results revealed a significant (p < 0.01 correlation between kind of mold species isolated from raw milk and dairy products. Similarly, a correlation was observed between dairy products and environmental sources. Regarding the high occurrence of mold contamination in raw milk and environmental sources, it seems that in some instances heat treatment was not effective enough to inactivate all molds; whereas in some other cases, cross contamination may have resulted in mold contamination. Therefore, it is crucial to maintain hygienic conditions during raw milk handling as well as processing steps. These practices could efficiently reduce the occurrence of mold contaminations in dairy products.

Full Text Available The purpose of the paper was to analyze the main trends in the milk and dairy products market in Romania in the period 2007-2012 and to set up the forecast for the 2013-2015 horizon, based on the empirical data provided by the National Institute of Statistics and Eurostat and using the fixed basis index, average change method, and comparison method. Milk production for consumption reached 210 thou tons in 2012 registering a descending trend. Despite that milk production decreased in the period 2007-2012, the production diversification applied by dairies supported the growth of dairy products output as follows: by 13.54 % for milk, by 3.45 % for sour cream, and by 13 % for butter. The forecast for the year 2015 provides that the production of dairy products will account for: 223,936.6 tons milk for consumption, 48,709.4 tons sour cream, 166,674.2 tons acidulated milk, 9,937.6 tons butter and 66,584.4 tons cheese. The development of milk processing imposes the improvement of production technologies, products quality, efficiency and competitiveness. Due to the unbalanced demand/offer ratio, after the elimination of milk quota, the Romanian milk and dairy products market will be invaded by foreign products.

Introduction: The high prevalence of obesity in children and adolescents is considered as a major global health concern and involves the onset of other comorbidities such as hypertension, dyslipidemia, chronic infl ammation and hyperinsulinemia, which are also considered as cardiovascular diseases risk factors. Several studies have observed that consumption of dairy products has a protective role on the development of cardiovascular diseases; however, the scientific evidence on this topic is very limited among children and adolescents. Objectives: To investigate the association between dairy products consumption and cardiovascular risk factors in young populations. Material and methods: The most up-to-date literature was reviewed, including some data from the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. A sample of adolescents (12.5-17.5 years) from 8 European cities was considered for the analysis. Results: US data showed a decrease in both number of servings and portion sizes of milk consumption. Within the HELENA study, dairy products emerged as the food group that better distinguished those adolescents at lower cardiovascular diseases risk. Among the HELENA adolescents, higher consumption of milk, yogurt and milk- and yogurt-based beverages was associated with lower body fat, lower risk for cardiovascular diseases, and higher cardiorespiratory fitness. Conclusions: More studies are needed to provide more evidence and to better understand the intrinsic mechanisms of the association between dairy products consumption, especially yogurt consumption, and obesity, diabetes, and other cardiovascular diseases risk factors.

The objective of this study was to estimate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the production chain of dairy products. Of 367 tested samples (36 bulk tank milk (BTM), 19 dairy products, 72 human, 185 animal, 55 equipment), 212 (57.8%) were found positive for S. aureus. Almost all isolates (99.6%) were resistant to at least one antimicrobial and 13.3% were multi-drug resistant (MDR), exhibiting resistance to three or more antibiotic classes. Eleven samples (3%) were found contaminated by MRSA carrying the mecA gene. None of the MRSA isolates carried the mecC or the Pandon-Valentine leucocidin (PVL) genes. Four spa types were identified among the MRSA isolates: t127, t3586, t1773, t4038, with t127 being the most prevalent (7 out of 11). Two of them, t3586 and t1773, were isolated for the first time in Greece. Furthermore, Pulse-Field Gel Electrophoresis (PFGE) analysis indicated clonal circulation through the dairy production chain. The presence of MDR S. aureus, and especially MRSA, in animals and dairy products represents a potential threat for the spread of this pathogen in the community. The results indicated that human, animal and environmental sources could be involved in the contamination of dairy products along their production chain and therefore further investigation of contamination sources is needed to control the dispersion of MRSA in the community.

2013-03-01

Full Text Available In order to determine the differences in the production and composition of biogas as well as the quality of digested residue from anaerobic digestion of the raw materials generated by dairy farms in Croatia, investigations were undertaken in the biogas laboratory facility of the Faculty of Agriculture. The investigated raw materials were: dairy manure, corn silage, haylage and equal-measure mix (1/3 of all raw materials. For each substrate, three runs of experiments were performed with the same overall hydraulic retention time (40 days and temperature of digestion (35 °C in mesophilic conditions. The investigations found that the most efficient production of biogas was from corn silage. As for biogas composition, it was acceptable in all investigated samples both in energy and environmental terms. Digested residues, which are mildly alkaline, have low dry matter content. About 70 % of dry matter content is organic. On the basis of N:P:K analysis and the analysis of biogenic elements values and heavy metal values, it can be concluded that digested residues of all input raw materials can be used in agricultural production.

Supply Chain Management as a Driving Force for Generating Competitive Advantage for Dairy Companies

Directory of Open Access Journals (Sweden)

Irina Olegovna Poleshkina

2016-11-01

Full Text Available The study aims to uncover the reserves to generate competitive advantages for the participants of the market of perishables in the case of the dairy sector due to the formation of effective supply chains, as this category of goods is the most demanding in terms of periods and conditions of transportation and terms of preservation. The research technique is based on the concepts of value chains and supply chain management. In order to optimize the distribution of functions between the participants of the dairy chain a process-based approach has been applied. The research has revealed the main reasons for high aggregate costs and the places of their formation at each stage of the dairy supply chain. The article proposes the mechanisms to address three main problems arising from the process of building relations between the participants of the dairy supply chain in Russia. These problems are associated with a disproportionate margin distribution between the participants of the chain, with non-compliance of the quality of raw milk with the requirements for the production of specific types of dairy products, and with distrust of the supply chain participants, which increases transaction costs and forces to create reserve supplies which reduce the competitiveness of the whole dairy supply chain in general. In order to improve the competitiveness of all participants in the dairy chain, the article presents several mechanisms for solving these problems. The first is margin distribution based on the costs incurred by each participant of the dairy chain. The second is the use of a mathematical model to determine the assortment of goods of a dairy enterprise on the basis of the incoming volume and quality of raw milk according to the seasonal factor and the demand for dairy products. The third is the feasibility of refusal from the formation of reserve supplies by all participants of the dairy chain, which will not only minimize aggregate costs, but also

Nutritional interventions to help prevent stunting, particularly in the first 1000 days from conception to 2 years of a child's life, are a major focus of numerous food aid organizations worldwide. Dairy ingredients can play an important role in enhancing the nutritional value and effectiveness of food products used in food aid. This article addresses gaps in research on malnutrition from both a broad perspective and specific to dairy ingredients. Narrative review. From a broad perspective, there is a need for gaining a consensus by the research community and funders of research on best practices for protocol development, outcomes measured, and reporting of study outcomes. Identification of biomarkers and rapid screening methods and consistent application of their use would expedite future research. A better understanding of nutritional requirements for malnourished populations, including the effects of energy deficits and disease on those requirements, is needed. More specific to dairy ingredients, a key research question is: Does dairy protein or the package of nutrients provided by dairy ingredients have a unique impact on growth, and if so, how? Also, data on the optimal levels of dairy ingredients based on the effective cost of treatment are needed, particularly in the treatment and prevention of moderate acute malnutrition and during pregnancy. © The Author(s) 2016.

Dairy farming has been playing a key role by improving household incomes and food security for rural communities in Sri Lanka. Nevertheless, it has failed to meet the expected self-sufficiency. In 2015, Sri Lanka imported 51percent of the national milk requirement spending US 251 million from its debt-ridden economy. This paper aims to analyse socio-economic characteristics of dairy farmers and factors affecting dairy production efficiency in the Uva Province of Sri Lanka, a highly potential area comprising all the dairy value chain actors. Surveyed was conducted to farmers, key informants from input suppliers, collectors, transporters, processors, sellers and support service providers. Result revealed that intensive farmer’s milk yields per cow was only 7.97 L/day, which was 35% and 60% higher than the yields of semi-intensive and extensive farmers respectively. The highest profit of Rs. 53.30 per litre was earned by extensive farmers, whereas it was Rs. 47.63 for semi-intensive and Rs. 44.76 for intensive farmers respectively if family labour cost was not taken into the account. The Technical Efficiency Analysis revealed that 37.1% and 20% milk production of intensive farmers and semi-intensive is being loss due to inefficiency and could be increased without any additional inputs. The main factors affecting efficiency in milk production included farmers’ socio-economic characteristics and farm characteristics. Based on the results it can be concluded that sustainability dairy production depends on farmer training, collectivizing farmers into farmer societies, culling unproductive male animals, increasing the availability and access to AI/other breading programs and low-cost quality concentrate feed and other supplements, and, thus appropriate measures should be taken to provide these conditions if Sri Lanka aims to achieve self-sufficiency in milk production.

The failure to adapt metabolism to the homeorhetic demands of lactation is considered as a main factor in reducing the productive life span of dairy cows. The so far defined markers of production performance and metabolic health in dairy cows do not predict the length of productive life span satisfyingly. This study aimed to identify novel pathways and biomarkers related to productive life in dairy cows by means of (targeted) metabolomics. In a longitudinal study from 42 days before up to 100 days after parturition, we identified metabolites such as long-chain acylcarnitines and biogenic amines associated with extended productive life spans. These metabolites are mainly secreted by the liver and depend on the functionality of hepatic mitochondria. The concentrations of biogenic amines and some acylcarnitines differed already before the onset of lactation thus indicating their predictive potential for continuation or early ending of productive life.

High consumption of soft drinks has been associated with lower intakes of milk and calcium-rich foods and higher body mass index (BMI). This study aimed to explore the pattern of beverage intake among Kuwaiti high-school students. A questionnaire on knowledge, attitudes and practices concerning beverages and milk and dairy products intake was completed by 190 Kuwaiti students aged 16-18 years and BMI was calculated for 181 of them. Intake of sweetened carbonated beverages and to a lesser extent packaged fruit juices affected the sufficiency of milk and dairy products intake among the sample of high-school students in Kuwait. Although BMI was not related to milk and dairy insufficiency, more of the overweight and obese students displayed incorrect practices. Nutritional education of high-school students on the importance of milk and dairy products as well as the hazards of excess sweetened carbonated beverages and packaged juice is recommended to prevent the obesity epidemic prevailing in Kuwait.

2016-03-01

Full Text Available Winter grazing provides a useful means for increasing the proportion of grazed herbage in the annual diet of dairy cows. This season is characterized by low herbage growth rate, low herbage allowance, and low herbage intake and hence greater needs for supplements to supply the requirements of lactating dairy cows. The aim of this study was to determine the influence of herbage allowance (HA offered to autumn calving dairy cows grazing winter herbage on milk production, nutritional status, and grazing behavior. The study took 63 d using 32 multiparous Holstein-Friesian dairy cows. Prior to experimental treatment, milk production averaged 20.2 ± 1.7 kg d-1, body weight was 503 ± 19 kg, and days in milking were 103 ± 6. Experimental animals were randomly assigned to two treatments according to HA offered above ground level: low (17 kg DM cow-1 d-1 vs. high HA (25 kg DM cow¹ d¹. All cows were supplemented with grass silage supplying daily 6.25 and 4.6 kg DM of concentrate (concentrate commercial plus high corn moisture. Decreasing HA influenced positively milk production (+25%, milk protein (+20 kg, and milk fat (+17 kg per hectare; however no effects on milk production per cow or energy metabolic status were observed in the cows. In conclusion, a low HA showed to be the most significant influencing factor on milk and milk solids production per hectare in dairy cows grazing restricted winter and supplemented with grass silage and concentrate; but no effect on the milk production per cow was found.

Feed and manure use in low-N-input and high-N-input dairy cattle production systems

2014-11-01

In most parts of Sub-Saharan Africa fertilizers and feeds are costly, not readily available and used sparingly in agricultural production. In many parts of Western Europe, North America, and Oceania fertilizers and feeds are relatively inexpensive, readily available and used abundantly to maximize profitable agricultural production. A case study, dairy systems approach was used to illustrate how differences in feed and manure management in a low-N-input dairy cattle system (Niger, West Africa) and a high-N-input dairy production system (Wisconsin, USA) impact agricultural production and environmental N loss. In Niger, an additional daily feed N intake of 114 g per dairy animal unit (AU, 1000 kg live weight) could increase annual milk production from 560 to 1320 kg AU-1, and the additional manure N could greatly increase millet production. In Wisconsin, reductions in daily feed N intake of 100 g AU-1 would not greatly impact milk production but decrease urinary N excretion by 25% and ammonia and nitrous oxide emissions from manure by 18% to 30%. In Niger, compared to the practice of housing livestock and applying dung only onto fields, corralling cattle or sheep on cropland (to capture urinary N) increased millet yields by 25% to 95%. The additional millet grain due to dung applications or corralling would satisfy the annual food grain requirements of 2-5 persons; the additional forage would provide 120-300 more days of feed for a typical head of cattle; and 850 to 1600 kg ha-1 more biomass would be available for soil conservation. In Wisconsin, compared to application of barn manure only, corralling heifers in fields increased forage production by only 8% to 11%. The application of barn manure or corralling increased forage production by 20% to 70%. This additional forage would provide 350-580 more days of feed for a typical dairy heifer. Study results demonstrate how different approaches to feed and manure management in low-N-input and high-N-input dairy cattle

The possible effects of dairy product intake against obesity have been suggested in animal studies; however, the association is still not well established in epidemiological studies. Few studies in Asian countries with relatively low intake of dairy products exist. We investigated the association between dairy products and calcium intake and obesity in Korean population with relatively low intake of dairy products. Our study population consisted of adults (n = 7173) aged 19-64 among participants of the 2007, 2008 and 2009 Korean National Health and Nutrition Examination Survey who had not made any attempt of intentional weight loss. Dietary intake data from food frequency questionnaire (FFQ) and 24-hour recall were used. Dairy products included milk and yogurt in the FFQ. Obesity was defined as BMI≥25 kg/m². Higher frequency of dairy product intake was associated with a reduced prevalence of obesity (OR = 0.63; 95% CI = 0.45-0.89 for ≥2 times/day vs. ≤1 time/month; p for trend = 0.003) using the intake data from FFQ. Similarly, high frequency of milk or yogurt intake had an inverse association with obesity. The association between milk and yogurt intake and obesity was similar when the intake from 24-hour recall was examined. Higher calcium intake from dairy products as well as total dietary calcium intake was associated with a decreased prevalence of obesity (OR = 0.83; 95% CI = 0.71-0.98 for highest vs. lowest quintile of dairy calcium intake; p for trend = 0.02, OR = 0.78; 95% CI = 0.64-0.94 for highest vs. lowest quintile of total calcium intake; p for trend = 0.04). The associations appeared to be stronger in women than in men. These results suggest that high consumption of dairy products is associated with a lower prevalence of obesity and that calcium in dairy products may be one of the components contributing to the association. Further longitudinal studies are warranted to replicate our findings.

Protein biomarker-based screening for detection of recombinant bovine somatotropin abuse in dairy cows

The aim of this article is to explore the current status of livestock resources, their status of utilisation and the future research concepts in dairy production and milk processing in Pakistan. Advances in the areas of genetics of dairy species, cow reproduction, nutrition, dairy chemistry, milk microbiology, processing technology and milk-based functional foods, have to be applied in Pakistan since the increase in Pakistan's population from 65 to 165 million over the past 3 decades is forecasted to an increase to 234 million by 2025. The need to increase food production means that competition for land and water resources will become more intense. The ecological sustainability of already fragile systems will be further challenged. Agro-industrial byproducts and non-conventional feed resources could be used for feeding of livestock, if farmers are trained accordingly. Situation may be significantly improved if fodder conservation techniques are introduced in livestock feeding systems. Pakistan needs a competitive and profitable dairy farming industry not just for economic but also environmental and social reasons. Productivity potential of local breeds is low and an attempt to genetically improve the local cattle through cross breeding has resulted in improvement in milk yield, acceleration in growth rates and higher prices; however, its discriminate use has been also associated with decreased immunity against temperature changes, disease and nutritional and environmental stresses prevailing in the region. The long-term effects of new systems (such as extended lactations, robot milking and all-year-round housing) will call for ever more intelligent approaches to the simultaneous achievement of quality systems that minimise environmental burdens, sustain high standards of health and welfare and deliver nutritionally valuable products into well organised food supply chains.

This study aimed to evaluate the rheological behavior and thermal conductivity of dairy products, composed of the same chemical components but with different formulations, as a function of temperature. Subsequently, thermal conductivity was related to the apparent viscosity of yogurt, fermented dairy beverage, and fermented milk. Thermal conductivity measures and rheological tests were performed at 5, 10, 15, 20, and 25°C using linear probe heating and an oscillatory rheometer with concentric cylinder geometry, respectively. The results were compared with those calculated using the parallel, series, and Maxwell-Eucken models as a function of temperature, and the discrepancies in the results are discussed. Linear equations were fitted to evaluate the influence of temperature on the thermal conductivity of the dairy products. The rheological behavior, specifically apparent viscosity versus shear rate, was influenced by temperature. Herschel-Bulkley, power law, and Newton's law models were used to fit the experimental data. The Herschel-Bulkley model best described the adjustments for yogurt, the power law model did so for fermented dairy beverages, and Newton's law model did so for fermented milk and was then used to determine the rheological parameters. Fermented milk showed a Newtonian trend, whereas yogurt and fermented dairy beverage were shear thinning. Apparent viscosity was correlated with temperature by the Arrhenius equation. The formulation influenced the effective thermal conductivity. The relationship between the 2 properties was established by fixing the temperature and expressing conductivity as a function of apparent viscosity. Thermal conductivity increased with viscosity and decreased with increasing temperature. Copyright © 2017 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

Manoury, E; Jourdon, K; Boyaval, P; Fourcassié, P

2013-03-01

We evaluated menaquinone contents in a large set of 62 fermented dairy products samples by using a new liquid chromatography method for accurate quantification of lipo-soluble vitamin K(2), including distribution of individual menaquinones. The method used a simple and rapid purification step to remove matrix components in various fermented dairy products 3 times faster than a reference preparation step. Moreover, the chromatography elution time was significantly shortened and resolution and efficiency were optimized. We observed wide diversity of vitamin K(2) contents in the set of fermented dairy products, from undetectable to 1,100 ng/g of product, and a remarkable diversity of menaquinone forms among products. These observations relate to the main microorganism species currently in the different fermented product technologies. The major form in this large set of fermented dairy products was menaquinone (MK)-9, and contents of MK-9 and MK-8 forms were correlated, that of MK-9 being around 4 times that of MK-8, suggesting that microorganisms able to produce MK-9 also produce MK-8. This was not the case for the other menaquinones, which were produced independently of each other. Finally, no obvious link was established between MK-9 content and fat content or pH of the fermented dairy products. Copyright © 2013 American Dairy Science Association. Published by Elsevier Inc.

Full Text Available A screening survey of the presence of aflatoxin M1 (AFM1 was carried out on 265 samples of cheese made from cow, buffalo, goat, sheep, sheep-goat milk collected in the Apulia region (Southern Italy. Selected samples included unripened, medium and long-term ripened cheeses. AFM1 was found in 16.6% of the analyzed samples. The highest positive incidence was for medium and long-term ripened cheeses, especially those made from sheep-goat milk, while buffalo cheeses tested consistently negative. Our results show that the level of contamination by AFM1 in dairy products from Apulia Region are lower than in other Italian and European regions. Moreover, it is important to underline that a common European norm concerning the AFM1 threshold limits for dairy products is still lacking.

Controversies Regarding the Role of Dairy Products in Inflammatory Bowel Disease

Seymour Mishkin

1994-01-01

Full Text Available Dairy products may affect inflammatory bowel disease (IBD patients who are either lactose intolerant or who are allergic to the proteins in these foods. The actual incidence of these conditions in IBD patients is not entirely clear. Whether either of these conditions results in benign symptomatic discomfort or can actually contribute to the relapse and/or clinical activity of IBD is also unclear. Physicians differ widely in the advice they give their patients; some dogmatically advise avoidance of dairy products when the diagnosis is made while others discount their possible role in the management of IBD. On the basis of the author’s and his group’s experience and review of the literature, a balanced and exploratory approach by patients, physicians and dieticians is advised.

Characterization of Dairy Production Systems and Analysis of Milk Promotion Strategies in Rural and Urban Areas in Niger: Case of the Urban Community of Niamey and Rural District of Filingue

Full Text Available Livestock breeding and particularly milk production play a major role in poverty alleviation and economic growth. The present study aimed at characterizing the production systems and opening avenues for milk production in a (suburban [urban community of Niamey (UCN] and in a rural environment [rural district of Filingue (RDF] in Niger. In UCN, surveys were carried out in 35 dairy sites randomly selected among the 150 already indexed within a radius of 50 km from the capital. Out of these, 12 sites were selected allowing the questionnaire to be administered to 169 heads of household. In RDF, 49 heads of household, located in five villages within 75 km of Filingue, were surveyed. Results showed that in UCN, breeders owned few dairy cows (five on average, i.e. 28% of the bovine herd, which produced in all seasons 7 to 10 L/household/day; they marketed fresh milk more often than in RDF because they had access to dairy transformation units. In RDF, they owned more cows (ten on average, i.e. 52% of the bovine herd, which produced only during the rainy season and the cold dry season (between 0 to 10 and 10 to 20 L/household/ day according to 66 and 20% of the persons surveyed, respectively; dairy products were transformed more often before sale (melted butter, curdled milk, cheese. The innovations observed in the surveyed breeders were related to changes in herd management. The constraints to dairy production development in the urban area concerned in particular production and preservation of good-quality fresh milk all the way to transforming units or consumers, while in the rural area, it concerned the lack of avenues. In urban areas, it is essential to organize the supply of food inputs, evening collection of milk and to popularize technical topics and innovating practices.

Dairy products are important in a healthy diet due to their high nutritional value; they are, however, associated with relatively large greenhouse gas emissions (GHGE) per kg product. When discussing the need to reduce the GHGE caused by the food system, it is crucial to consider the nutritional value of alternative food choices. The objective of this study was to elucidate the role of dairy products in overall nutrition and to clarify the effects of dietary choices on GHGE, and to combine nutritional value and GHGE data. We created eight dietary scenarios with different quantity of dairy products using data from the Danish National Dietary Survey (1995-2006). Nutrient composition and GHGE data for 71 highly consumed foods were used to estimate GHGE and nutritional status for each dietary scenario. An index was used to estimate nutrient density in relation to nutritional recommendation and climate impact for solid food items; high index values were those with the highest nutrient density scores in relation to the GHGE. The high-dairy scenario resulted in 27% higher protein, 13% higher vitamin D; 55% higher calcium; 48% higher riboflavin; and 18% higher selenium than the non-dairy scenario. There was a significant correlation between changes in calcium and changes in vitamin D, selenium, and riboflavin content (P=0.0001) throughout all of the diets. The estimated GHGE for the dietary scenario with average-dairy consumption was 4,631 g CO2e/day. When optimizing a diet with regard to sustainability, it is crucial to account for the nutritional value and not solely focus on impact per kg product. Excluding dairy products from the diet does not necessarily mitigate climate change but in contrast may have nutritional consequences.

The effects of existing food safety management systems and size of the production facility on microbiological quality in the dairy industry in Kenya were studied. A microbial assessment scheme was used to evaluate 14 dairies in Nairobi and its environs, and their performance was compared based on their size and on whether they were implementing hazard analysis critical control point (HACCP) systems and International Organization for Standardization (ISO) 22000 recommendations. Environmental samples from critical sampling locations, i.e., workers' hands and food contact surfaces, and from end products were analyzed for microbial quality, including hygiene indicators and pathogens. Microbial safety level profiles (MSLPs) were constructed from the microbiological data to obtain an overview of contamination. The maximum MSLP score for environmental samples was 18 (six microbiological parameters, each with a maximum MSLP score of 3) and that for end products was 15 (five microbiological parameters). Three dairies (two large scale and one medium scale; 21% of total) achieved the maximum MSLP scores of 18 for environmental samples and 15 for the end product. Escherichia coli was detected on food contact surfaces in three dairies, all of which were small scale dairies, and the microorganism was also present in end product samples from two of these dairies, an indication of cross-contamination. Microbial quality was poorest in small scale dairies. Most operations in these dairies were manual, with minimal system documentation. Noncompliance with hygienic practices such as hand washing and cleaning and disinfection procedures, which is common in small dairies, directly affects the microbial quality of the end products. Dairies implementing HACCP systems or ISO 22000 recommendations achieved maximum MSLP scores and hence produced safer products.

It has been proposed that livestock production effluents such as wastewater, airborne dust and manure increase the density of antimicrobial resistant bacteria and genes in the environment. The public health risk posed by this proposed outcome has been difficult to quantify using traditional microbiological approaches. We utilized shotgun metagenomics to provide a first description of the resistome of North American dairy and beef production effluents, and identify factors that significantly impact this resistome. We identified 34 mechanisms of antimicrobial drug resistance within 34 soil, manure and wastewater samples from feedlot, ranch and dairy operations. The majority of resistance-associated sequences found in all samples belonged to tetracycline resistance mechanisms. We found that the ranch samples contained significantly fewer resistance mechanisms than dairy and feedlot samples, and that the resistome of dairy operations differed significantly from that of feedlots. The resistome in soil, manure and wastewater differed, suggesting that management of these effluents should be tailored appropriately. By providing a baseline of the cattle production waste resistome, this study represents a solid foundation for future efforts to characterize and quantify the public health risk posed by livestock effluents.

Commercial milking of sheep is a new agricultural industry in the United States starting approximately 30 yr ago. The industry is still small, but it is growing. The majority of the sheep milk is used in the production of specialty cheeses. The United States is the major importer of sheep milk cheeses with 50 to 60% of annual world exports coming to the United States during the past 20 yr. Therefore, there is considerable growth potential for the industry in the United States. The only dairy sheep research flock in North America is located at the Spooner Agricultural Research Station of the University of Wisconsin-Madison. The research program started in 1993 and has been multifaceted; dealing with several areas important to commercial dairy sheep farmers. The East Friesian and Lacaune dairy breeds were compared and introduced to the industry through the research program. Both dairy breeds produced significantly more milk than traditional meat-wool breeds found in the U.S., but the two breeds differed in their production traits. East Friesian-cross ewes produced more lambs and slightly more milk than Lacaune-cross ewes whereas Lacaune-cross ewes produced milk with a higher percentage of fat and protein than East Friesian-cross ewes. Lactation physiology studies have shown that ewes with active corpora lutea have increased milk yields, oxytocin release during milking is required to obtain normal fat percentages in the milk, large udder cisterns of dairy ewes can allow for increased milking intervals, and short daylengths during late pregnancy results in increased milk yield. In the nutrition area, legume-grass pastures and forages with a higher percentage of legume will result in increased milk production. Grazing ewes respond to additional supplementation with increased milk yield, but it is important to match the supplement to the quality of the grazing. Ewes on high quality legume-grass pastures that are high in rumen degradable protein respond with increased

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, mainly through the process of replacing or including beneficial bacteria in the gastrointestinal tract. Fermented dairy foods such as yogurt, fermented milk and cheese are the major vehicle in delivering probiotics, and probiotic delivery have been traditionally associated with these fermented dairy foods. Additionally, many other non-dairy probiotic products and non-food form ...

Recommendations for daily calcium intake from dairy products are variable and based on local consensus. To investigate whether patients with a recent fracture complied with these recommendations, we quantified the daily dairy calcium intake including milk, milk drinks, pudding, yoghurt, and cheese in a Dutch cohort of fracture patients and compared outcomes with recent data of a healthy U.S. cohort (80% Caucasians). An observational study analyzed dairy calcium intakes of 1526 female and 372 male Dutch fracture patients older than 50. On average, participants reported three dairy servings per day, independently of age, gender or population density. Median calcium intake from dairy was 790 mg/day in females and males. Based on dairy products alone, 11.3% of women and 14.2% of men complied with Dutch recommendations for calcium intake (adults ≤ 70 years: 1100 mg/day and >70 years: 1200 mg/day). After including 450 mg calcium from basic nutrition, compliance raised to 60.5% and 59.1%, respectively, compared to 53.2% in the U.S. cohort. Daily dairy calcium intake is not associated with femoral neck bone mineral density (BMD) T-scores or WHO Fracture Assessment Tool (FRAX) risk scores for major fracture or hip fracture. However, when sub analyzing the male cohort, these associations were weakly negative. The prevalence of maternal hip fracture was a factor for current fracture risks, both in women and men. While daily dairy calcium intake of Dutch fracture patients was well below the recommended dietary intake, it was comparable to intakes in a healthy U.S. cohort. This questions recommendations for adding more additional dairy products to preserve adult skeletal health, particularly when sufficient additional calcium is derived from adequate non-dairy nutrition.

Potential impact of the growth hormone and other technology on the United States dairy industry by the year 2000.

Science.gov (United States)

Mix, L S

1987-02-01

The United States dairy industry is projected to go through a major transition by the 2000 with some regions experiencing more change than others. Population growth plus medical discoveries favorable to certain dairy products combined with strengthened marketing programs could increase consumption of milk equivalent from the present 66.3 to 72.1 million metric tons by the yr 2000. Ongoing genetic, feeding, and management improvements could raise average milk production per cow from the 1984 level of 5,680 kg to 7,425 kg by 2000. If growth hormone biotechnology is adopted, average production per cow could reach 9,281 kg by the 21st century. This could reduce US dairy cow numbers 30% from the present 11.1 million to 7.8 million by the yr 2000. Likewise, the dairy industry and others could expect approximately 92,500 fewer commercial dairy farms, a decrease of 51%. This would mean 195,000 fewer employees and 3.6 to 4.1 million fewer crop hectares would be required. A transition of this magnitude will require indepth planning by legislators, policy makers, university teaching, research, and extension personnel, agribusiness, industry representatives, and dairy producers to cope with the necessary adjustments.

Improvement of Dairy Cattle Productivity Through Early Non-Pregnancy Diagnosis

International Nuclear Information System (INIS)

Indetie, D.

2002-01-01

Reproductive wastage bears a great deal on the productivity of dairy cattle by prolonging the calving intervals thereby reducing the milk produced and the number of calves born over the lifetime of a cow. early identification of a non-cyclic or non-pregnant cows can result in early intervention and rebreeding of the affected cattle ths improving productivity. Determination of progesterone levels in milk can be used as a good indicator of the reproductive status of dairy cows. five hundred and thirty two cows were sampled by collecting milk sample on day of AI, day 12 and 13 and day 22 to 24 after AI. The milk samples were assayed to determine progesterone levels at these stages of the estrus cycle, which were then used to deduce the reproductive status of the cow. Out of the cows sampled 16% were not cycling and had progesterone levels of 1 nm/L or less during the mid luteal phase. Insemination of cows whose Progesterone levels were less than 3 nm/L resulted in conception rates of 80% and indication of the timeliness of insemination. Inseminating cows 19 hours after onset of standing heat resulted in conception rates of 79% compared with insemination early whose conception rates were 15%.It can be concluded that the timeliness of AI will determine the success of conception rates if heat is detected properly and the cow is in the right reproductive state. Early non-pregnancy diagnosis using progesterone can reduce the anoestrus period as well as detecting cows with reproductive anomalies which can be rectified early and the cows presented for rebreeding thus reducing the calving interval and improving the productivity of the dairy enterprise

ADSA Foundation Scholar Award: Trends in culture-independent methods for assessing dairy food quality and safety: emerging metagenomic tools.

Science.gov (United States)

Yeung, Marie

2012-12-01

Enhancing the quality and safety of dairy food is critical to maintaining the competitiveness of dairy products in the food and beverage market and in reinforcing consumer confidence in the dairy industry. Raw milk quality has a significant effect on finished product quality. Several microbial groups found in raw milk have been shown to adversely affect the shelf life of pasteurized milk. Current microbiological criteria used to define milk quality are based primarily on culture-dependent methods, some of which are perceived to lack the desired sensitivity and specificity. To supplement traditional methods, culture-independent methods are increasingly being used to identify specific species or microbial groups, and to detect indicator genes or proteins in raw milk or dairy products. Some molecular subtyping techniques have been developed to track the transmission of microbes in dairy environments. The burgeoning "-omics" technologies offer new and exciting opportunities to enhance our understanding of food quality and safety in relation to microbes. Metagenomics has the potential to characterize microbial diversity, detect nonculturable microbes, and identify unique sequences or other factors associated with dairy product quality and safety. In this review, fluid milk will be used as the primary example to examine the adequacy and validity of conventional methods, the current trend of culture-independent methods, and the potential applications of metagenomics in dairy food research.

Full Text Available We aimed to investigate the association between dairy product consumption and the risk of obesity and metabolic syndrome (MetS in Korean adults. Data from 13,692 Korean adults aged ≥19 years from the KNHANES 2010–2013 were used. The study participants were divided into three groups according to the serving size of dairy products they consumed based on a single 24-h recall. About 58% of the Korean adults did not consume any dairy products in one day. In both the sexes, only those who adhered to the recommendation for dairy products (≥1 serving/day achieved the daily requirement of calcium. Women who consumed ≥1 serving/day of dairy products had lower risks of obesity (body mass index ≥ 25 kg/m2 (adjusted odds ratio (AOR, 0.77; 95% confidence interval (CI, 0.66–0.89; p for trend < 0.01 and MetS (AOR, 0.67; 95% CI, 0.56–0.80; p for trend < 0.01 than women who did not consume dairy products. However, these significant associations were not observed in men. In conclusion, consuming ≥ 1 serving/day of dairy products could be an easy and efficient strategy for meeting daily calcium requirement as well as lowering risks of obesity and MetS among Korean women.

Full Text Available Merapi disaster with a variety of volcanic material caused fatalities or death and directly influenced on the health of cattle. Both of these effects in addition to psychological effects that cause farmers panic and economically are very harmful. This study aims to analyze the impact of Merapi disaster on dairy cow production and estimate the economic losses on the dairy cattle business. The analysis showed that Merapi disaster caused the death of livestock and reduced milk production. Livestock deaths are mainly caused by hot clouds, lava and ash that consumed through food and the respiratory tract. Decrease in milk production varies from 6.7 percent to 84 percent. Cows that are left displaced and not given food and drink for four days obviously decreased in milk production. The death of livestock, disruption of institutional marketing input and output, falling livestock prices and the decline in milk production resulted in losses IDR. 21.0 billion.

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.

Inadequate consumption of dairy products without appropriate dietary substitution may have deleterious health consequences. Social research reveals the factors that may impede compliance with dietary recommendations. This is particularly important given the recent introduction of functional dairy products. One of the challenges for public health professionals is to demonstrate the efficacy of nutrition education in improving attitudes toward nutrient rich foods. The aim of this study was to explore the salient beliefs of adult weight loss trial participants regarding both traditional and functional dairy products and to compare these with a control group not exposed to nutrition education. Six focus groups were conducted, three with weight loss trial completers (n = 15) that had received nutrition education and three with individuals from the same region (n = 14) to act as controls. Transcribed focus groups were coded using the Theory of Planned Behaviour theoretical framework. Non-trial participants perceived dairy foods as weight inducing and were sceptical of functional dairy products. A lack of time/ability to decipher dairy food labels was also discussed by these individuals. In contrast trial participants discussed several health benefits related to dairy foods, practised label reading and were confident in their ability to incorporate dairy foods into their diet. Normative beliefs expressed were similar for both groups indicating that these were more static and less amenable to change through nutrition education than control and behavioural beliefs. Nutrition education provided as a result of weight loss trial participation influenced behavioural and control beliefs relating to dairy products. This study provides a proof of concept indication that nutrition education may improve attitudes towards dairy products and may thus be an important target for public health campaigns seeking to increase intake of this food group.

Full Text Available The objective of this study was to characterize and to analyze the room for manoeuvre in time in dairy production systems (DPS. Two interviews were conducted in twenty DPS in the Northern region of Paraná, Brazil, with the following objectives: to know the management and practices involving the herd, the land area and the commercialization; and to qualify and evaluate the work organization. In order to build the variables, the repertory grid method was used, and for the typology, the graphic methodology of Bertin adapted to small samples was used. The results showed that the room for manoeuvre in time of the DPS, quantified in hours available per year, varied between the farmers and was related to routine work and seasonal work durations, as well as the autonomy of farmers to perform both works. The routine work was related to the number of cows, but was also explained by the herd management, by the transport equipment for the feed and by the workforce composition. Four types of work organization were identified between sampled DPS, based on room for manoeuvre in time and how they were built. Knowing the room for manoeuvre time and its variables, it is possible to guide the farmers to adjust their dairy production system in order to have more time available for other activities or to develop the dairy production system.

A national US survey collected data on herd milk production and management of Holstein herds. Step-wise selection identified management practices that were related to herd milk production using only operations that calculated herd milk production as well as using data from all operations. Results were similar. Milk production was highest in the West. Operations with 25% registered cattle had higher production than operations with no registered cattle. Dairy operations that reported a mean BW > 545 kg at first calving had higher mean milk production than operations with a mean BW or = 27 mo at first calving. In addition, use of the following management practices was associated with higher rolling herd average milk production: calves born in individual areas in buildings, calves hand-fed first colostrum, starter grain fed to preweaned calves, ionophores fed to heifers from birth to first calving, DHIA record-keeping system used, computerized records, and no new cattle introduced in the previous 12 mo.

The role of dairy products and milk in adolescent obesity: evidence from Hong Kong's "Children of 1997" birth cohort.

Directory of Open Access Journals (Sweden)

Shi Lin Lin

Full Text Available BACKGROUND: Observational studies, mainly from Western populations, suggest dairy consumption is inversely associated with adiposity. However, in these populations the intake range is limited and both diet and obesity may share social patterning. Evidence from non-Western developed settings with different social patterning, is valuable in distinguishing whether observed associations are biologically mediated or socially confounded. OBJECTIVE: To examine the associations of milk or other dairy product consumption with adolescent obesity. METHODS: We used multivariable linear regression models to examine the associations of milk or other dairy product consumption, obtained from a food frequency questionnaire, at 11 years with body mass index (BMI z-scores at 13 years and waist hip ratio (WHR at 11 years, in 5,968 adolescents from a Chinese birth cohort, comprising 88% of births in April and May 1997. We used multiple imputation for missing exposures and confounders. RESULTS: Only 65.7% regularly consumed milk and 72.4% other dairy products. Milk and other dairy product consumption was positively associated with socio-economic position but not with BMI z-score or WHR, with or without adjustment for sex, mother's birthplace, parental education, physical activity and other food consumption. CONCLUSIONS: The lack of association of milk and other dairy product consumption with adiposity in a non-Western setting was not consistent with the majority of evidence from Western settings. Observed anti-obesigenic effects in Western settings may be due to socially patterned confounding.

Staphylococcus aureus entrance into the dairy chain: Tracking S. aureus from dairy cow to cheese

Full Text Available Staphylococcus aureus is one of the most important contagious mastitis pathogens in dairy cattle. Due to its zoonotic potential, control of S. aureus is not only of great economic importance in the dairy industry but also a significant public health concern. The aim of this study was to decipher the potential of bovine udder associated S. aureus as reservoir for S. aureus contamination in dairy production and processing. From 18 farms, delivering their milk to an alpine dairy plant for the production of smeared semi-hard and hard cheese. 1176 quarter milk (QM samples of all cows in lactation (n = 294 and representative samples form bulk tank milk (BTM of all farms were surveyed for coagulase positive (CPS and coagulase negative Staphylococci (CNS. Furthermore, samples from different steps of the cheese manufacturing process were tested for CPS and CNS. As revealed by chemometric-assisted FTIR spectroscopy and molecular subtyping (spa typing and multi locus sequence typing, dairy cattle represent indeed an important, yet underreported, entrance point of S. aureus into the dairy chain. Our data clearly show that certain S. aureus subtypes are present in primary production as well as in the cheese processing at the dairy plant. However, although a considerable diversity of S. aureus subtypes was observed in QM and BTM at the farms, only certain S. aureus subtypes were able to enter and persist in the cheese manufacturing at the dairy plant and could be isolated from cheese until day fourteen of ripening. Farm strains belonging to the FTIR cluster B1 and B3, which show genetic characteristics (t2953, ST8, enterotoxin profile: sea/sed/sej of the recently described S. aureus genotype B, most successfully contaminated the cheese production at the dairy plant. Thus our study fosters the hypothesis that genotype B S. aureus represent a specific challenge in control of S. aureus in the dairy chain that requires effective clearance strategies and hygienic

Low fat dairy products are part of dietary guidelines to prevent stroke. However, epidemiological evidence is inconclusive with regard to the association between dairy products and stroke. We therefore investigated associations for substitutions between dairy product subgroups and risk of total stroke and stroke subtypes. We included 55,211 Danish men and women aged 50-64 years without previous stroke. Baseline diet was assessed by a food frequency questionnaire. Cases were identified through a national register and subsequently verified. The associations were analyzed using Cox proportional hazard regression. During a median follow-up of 13.4 years, we identified 2272 strokes, of which 1870 were ischemic (318 large artery atherosclerotic, 839 lacunar, 102 cardioembolic, 98 other determined types, 513 of unknown type), 389 were hemorrhages (273 intracerebral, 116 subarachnoid) and 13 of unknown etiology. Substitution of semi-skimmed fermented milk or cheese for whole-fat fermented milk was associated with a higher rate of ischemic stroke [semi-skimmed fermented milk: hazard ratio (HR) = 1.20 (95% confidence interval (CI) 0.99-1.45), cheese: HR = 1.14 (95% CI 0.98-1.31) per serving/day substituted] and substitutions of whole-fat fermented milk for low-fat milk, whole-fat milk or buttermilk were associated with a lower rate [low-fat milk: HR = 0.85 (95% CI 0.74-0.99), whole-fat milk: HR = 0.84 (95% CI 0.71-0.98) and buttermilk: HR = 0.83 (95% CI 0.70-0.99)]. We observed no associations for substitutions between dairy products and hemorrhagic stroke. Our results suggest that intake of whole-fat fermented milk as a substitution for semi-skimmed fermented milk, cheese, buttermilk or milk, regardless of fat content, is associated with a lower rate of ischemic stroke.

Full Text Available ABSTRACT: Introduction & Objective: Cholesterol is an important compound in most of the biological reactions which the excess of it can be seen as a harmful compound of causing heart diseases. The aim of the present study was to evaluate the cholesterol removal property and also its pathway by dairy lactobacillus in in vitro condition under different bile salts concentration. Materials & Methods: After isolation of lactobacillus strains from dairy products, they were identified with chemical tests and their growths were evaluated under presence of cholesterol and bile salts. The method of action of the bacillus in cholesterol removal was assayed by spectrophotometer method. Collected data was analyzed by SPSS software. Results: result of this study showed that any strains of the bacteria had the ability of cholesterol removal (7.82-34.69 µg/ml. L.casei had more competence for removal of cholesterol in compare to the rest of bacilli. The evaluation of cholesterol cell wall attachment revealed that most of removed cholesterols have been changed to the other products. Conclusion: Considering the result of this study, it can be concluded that cholesterol removal has a direct association with growth of bacteria where the L. casei with high growth rate had more capability of cholesterol removal. Whereas the Lactobacillus can remove the cholesterol with different methods, results of this study showed that dairy products, especially yogurt, can remove the harmful substances such as cholesterol using non chemical methods. The results of this study could be expanded on human use if more study and research could be carried out.

Metabolomics to Explore Impact of Dairy Intake

Directory of Open Access Journals (Sweden)

Hong Zheng

2015-06-01

Full Text Available Dairy products are an important component in the Western diet and represent a valuable source of nutrients for humans. However, a reliable dairy intake assessment in nutrition research is crucial to correctly elucidate the link between dairy intake and human health. Metabolomics is considered a potential tool for assessment of dietary intake instead of traditional methods, such as food frequency questionnaires, food records, and 24-h recalls. Metabolomics has been successfully applied to discriminate between consumption of different dairy products under different experimental conditions. Moreover, potential metabolites related to dairy intake were identified, although these metabolites need to be further validated in other intervention studies before they can be used as valid biomarkers of dairy consumption. Therefore, this review provides an overview of metabolomics for assessment of dairy intake in order to better clarify the role of dairy products in human nutrition and health.

Dairy sheep production research at the University of Wisconsin-Madison, USA – a review

2014-01-01

Commercial milking of sheep is a new agricultural industry in the United States starting approximately 30 yr ago. The industry is still small, but it is growing. The majority of the sheep milk is used in the production of specialty cheeses. The United States is the major importer of sheep milk cheeses with 50 to 60% of annual world exports coming to the United States during the past 20 yr. Therefore, there is considerable growth potential for the industry in the United States. The only dairy sheep research flock in North America is located at the Spooner Agricultural Research Station of the University of Wisconsin-Madison. The research program started in 1993 and has been multifaceted; dealing with several areas important to commercial dairy sheep farmers. The East Friesian and Lacaune dairy breeds were compared and introduced to the industry through the research program. Both dairy breeds produced significantly more milk than traditional meat-wool breeds found in the U.S., but the two breeds differed in their production traits. East Friesian-cross ewes produced more lambs and slightly more milk than Lacaune-cross ewes whereas Lacaune-cross ewes produced milk with a higher percentage of fat and protein than East Friesian-cross ewes. Lactation physiology studies have shown that ewes with active corpora lutea have increased milk yields, oxytocin release during milking is required to obtain normal fat percentages in the milk, large udder cisterns of dairy ewes can allow for increased milking intervals, and short daylengths during late pregnancy results in increased milk yield. In the nutrition area, legume-grass pastures and forages with a higher percentage of legume will result in increased milk production. Grazing ewes respond to additional supplementation with increased milk yield, but it is important to match the supplement to the quality of the grazing. Ewes on high quality legume-grass pastures that are high in rumen degradable protein respond with increased

Improving the feed efficiency of dairy cattle has a substantial effect on the economic efficiency and on the reduction of harmful environmental effects of dairy production through lower feeding costs and emissions from dairy farming. To assess the economic importance of feed efficiency in the breeding goal for dairy cattle, the economic values for the current breeding goal traits and the additional feed efficiency traits for Finnish Ayrshire cattle under production circumstances in 2011 were determined. The derivation of economic values was based on a bioeconomic model in which the profit of the production system was calculated, using the generated steady state herd structure. Considering beef production from dairy farms, 2 marketing strategies for surplus calves were investigated: (A) surplus calves were sold at a young age and (B) surplus calves were fattened on dairy farms. Both marketing strategies were unprofitable when subsidies were not included in the revenues. When subsidies were taken into account, a positive profitability was observed in both marketing strategies. The marginal economic values for residual feed intake (RFI) of breeding heifers and cows were -25.5 and -55.8 €/kg of dry matter per day per cow and year, respectively. The marginal economic value for RFI of animals in fattening was -29.5 €/kg of dry matter per day per cow and year. To compare the economic importance among traits, the standardized economic weight of each trait was calculated as the product of the marginal economic value and the genetic standard deviation; the standardized economic weight expressed as a percentage of the sum of all standardized economic weights was called relative economic weight. When not accounting for subsidies, the highest relative economic weight was found for 305-d milk yield (34% in strategy A and 29% in strategy B), which was followed by protein percentage (13% in strategy A and 11% in strategy B). The third most important traits were calving

Spontaneous milk fermentation has a long history in Mongolia, and beneficial microorganisms have been handed down from one generation to the next for use in fermented dairy products. The objective of this study was to investigate the diversity of lactic acid bacteria (LAB) communities in fermented yak, mare, goat, and cow milk products by analyzing 189 samples collected from 13 different regions in Mongolia. The LAB counts in these samples varied from 3.41 to 9.03 log cfu/mL. Fermented yak and mare milks had almost identical mean numbers of LAB, which were significantly higher than those in fermented goat milk but slightly lower than those in fermented cow milk. In total, 668 isolates were obtained from these samples using de Man, Rogosa, and Sharpe agar and M17 agar. Each isolate was considered to be presumptive LAB based on gram-positive and catalase-negative properties, and was identified at the species level by 16S rRNA gene sequencing, multiplex PCR assay, and restriction fragment length polymorphism analysis. All isolates from Mongolian dairy products were accurately identified as Enterococcus faecalis (1 strain), Enterococcus durans (3 strains), Lactobacillus brevis (3 strains), Lactobacillus buchneri (2 strains), Lactobacillus casei (16 strains), Lactobacillus delbrueckii ssp. bulgaricus (142 strains), Lactobacillus diolivorans (17 strains), Lactobacillus fermentum (42 strains), Lactobacillus helveticus (183 strains), Lactobacillus kefiri (6 strains), Lactobacillus plantarum ssp. plantarum (7 strains), Lactococcus lactis ssp. lactis (7 strains), Leuconostoc lactis (22 strains), Leuconostoc mesenteroides (21 strains), Streptococcus thermophilus (195 strains), and Weissella cibaria (1 strain). The predominant LAB were Strep. thermophilus and Lb. helveticus, which were isolated from all sampling sites. The results demonstrate that traditional fermented dairy products from different regions of Mongolia have complex compositions of LAB species. Such diversity of

Still the productivity indicator of 4500 kg/year of milk from a cow is low enough and does not correspond to the general world-wide tendencies. This suggests the need for further assessment of the existing list of tools with a view to adjusting them and defining priorities for the State support of the DPS of AIC.

Full Text Available Milk is one of the most important foods for mammals, because it is the first form of feed providing energy, nutrients and immunological factors. In the last few years, milk lipids have attracted the attention of researchers due to the presence of several bioactive components in the lipid fraction. The lipid fraction of milk and dairy products contains several components of nutritional significance, such as ω-3 and ω-6 polyunsaturated fatty acids, CLA, short chain fatty acids, gangliosides and phospholipids. Prospective cohort evidence has shown that phospholipids play an important role in the human diet and reinforce the possible relationship between their consumption and prevention of several chronic diseases. Because of these potential benefits of phospholipids in the human diet, this review is focused on the recent advances in phospholipids from colostrum, milk and dairy by-products. Phospholipid composition, its main determination methods and the health activities of these compounds will be addressed.

Full Text Available Despite the ever-increasing number of patients with dementia worldwide, fundamental therapeutic approaches to this condition have not been established. Epidemiological studies suggest that intake of fermented dairy products prevents cognitive decline in the elderly. However, the active compounds responsible for the effect remain to be elucidated. The present study aims to elucidate the preventive effects of dairy products on Alzheimer's disease and to identify the responsible component. Here, in a mouse model of Alzheimer's disease (5xFAD, intake of a dairy product fermented with Penicillium candidum had preventive effects on the disease by reducing the accumulation of amyloid β (Aβ and hippocampal inflammation (TNF-α and MIP-1α production, and enhancing hippocampal neurotrophic factors (BDNF and GDNF. A search for preventive substances in the fermented dairy product identified oleamide as a novel dual-active component that enhanced microglial Aβ phagocytosis and anti-inflammatory activity towards LPS stimulation in vitro and in vivo. During the fermentation, oleamide was synthesized from oleic acid, which is an abundant component of general dairy products owing to lipase enzymatic amidation. The present study has demonstrated the preventive effect of dairy products on Alzheimer's disease, which was previously reported only epidemiologically. Moreover, oleamide has been identified as an active component of dairy products that is considered to reduce Aβ accumulation via enhanced microglial phagocytosis, and to suppress microglial inflammation after Aβ deposition. Because fermented dairy products such as camembert cheese are easy to ingest safely as a daily meal, their consumption might represent a preventive strategy for dementia.

Livestock is a one of the major sources of livelihood for most of the small and marginal farmers in India, particularly for rural households who live in below poverty line. Extension interventions have long been seen as a key element for enabling farmers to obtain information and technologies that can improve their livelihoods. It is also recognized that extension is an important factor in promoting dairy development. Ex-post-facto cause to effect research design was applied in this study to trace out the impact of extension interventions in improving knowledge, attitude, adoption towards scientific dairy farming practices and improvement in milk production of dairy animal and income from dairying which will be resulted into improved livelihood of rural poor in Nadia district of West Bengal, India. Therefore, 60 dairy farmers of experimental villages who were considered as beneficiaries and 60 dairy farmers of control villages who were considered as non-beneficiaries were selected as sample for the study. It was found that beneficiaries had significantly higher score in all the five components of livelihood improvement with its all sub components, i.e., knowledge, attitude, adoption of scientific dairy farming practices, milk production per household per day and monthly income from dairying except disease control, and marketing component of adoption. Hence, it may be concluded that extension interventions had a significant impact on improving livelihood of rural dairy farmers in Nadia district of West Bengal, India.

The study evaluated the antimicrobial resistance of molecularly characterized strains of Staphylococcus aureus and S. saprophyticus isolated from 3 Lebanese dairy-based food products that are sometimes consumed raw: kishk, shanklish and baladi cheese. Suspected Staphylococcus isolates were identified initially using standard biochemical tests, then strains that were confirmed by polymerase chain reaction (29 S. aureus and 17 S. saprophyticus) were evaluated for their susceptibility to different antimicrobials. The highest levels of contamination with staphylococci were in baladi cheese. Resistance rates ranged from 67% to gentamicin to 94% to oxacillin and clindamycin. The results suggest that these locally made dairy-based foods may act as vehicles for the transmission of antimicrobial-resistant Staphylococcus spp.

Full Text Available A survey was conducted in 2012 to assess the impact of dairy technologies on the livelihood of dairying households in Ada’a and Lume districts of central Ethiopia. A total of 108 dairy farms were interviewed using structured questionnaire. Dairying has significant contribution as a sustainable source of income to the dairy producing households. It contributed about 62% and 66% of the total monthly income in Ada’a and Lume districts, respectively. Dairying was the first income source for about 80% and 62% of the dairy producing households in Ada’a and Lume districts, respectively. On the other hand, 92.9 % and 88.9 % of the respondents in Ada’a and Lume districts respectively explained that dairy technology adoption has significantly increased their household income. About 56% and 32% of households in Ada’a and Lume districts were found to save money from dairying in a traditional form of saving. Adoption of dairy technologies has also an impact on the consumption of milk and milk products as all family members in about 77.5% and 87.1% of households in Ada’a and Lume districts, respectively could consume more milk.

2016-09-01

Full Text Available Background and Aim: There are global public health and economic concerns on chemical residues in food of animal origin. The use of antibiotics in dairy cattle for the treatment of diseases such as mastitis has contributed to the presence of residues in dairy products. Penicillin residues as low as 1 ppb can lead to allergic reactions and shift of resistance patterns in microbial population as well as interfere with the processing of several dairy products. Antibiotic monitoring is an essential quality control measure in safe milk production. This study was aimed at determining antibiotic residue contamination and the level of penicillin in dairy products from Fulani cattle herds in Oyo State. Materials and Methods: The presence of antibiotic residues in 328 samples of fresh milk, 180 local cheese (wara, and 90 fermented milk (nono from Southwest, Nigeria were determined using Premi® test kit (R-Biopharm AG, Germany followed by high-performance liquid chromatography analysis of penicillin-G residue. Results: Antibiotic residues were obtained in 40.8%, 24.4% and 62.3% fresh milk, wara and nono, respectively. Penicillin-G residue was also detected in 41.1% fresh milk, 40.2% nono and 24.4% wara at mean concentrations of 15.22±0.61, 8.24±0.50 and 7.6±0.60 μg/L with 39.3%, 36.7% and 21.1%, respectively, containing penicillin residue above recommended Codex maximum residue limit (MRL of 5 μg/L in dairy. There was no significant difference between the mean penicillin residues in all the dairy products in this study. Conclusion: The results are of food safety concern since the bulk of the samples and substantial quantities of dairy products in Oyo state contained violative levels of antibiotic residues including penicillin residues in concentrations above the MRL. This could be due to indiscriminate and unregulated administration of antibiotics to dairy cattle. Regulatory control of antibiotic use, rapid screening of milk and dairy farmers�

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.

Milk and Cheese in an Andean Country: What Place for the Peruvian Traditional Subsector Faced with Dairy Industries?

2007-01-01

Full Text Available Since the beginning of the 1990s, Peruvian milk production has increased greatly. The development of dairy supply chains is linked to the growth of a market protected from importations, and which is expanding because of urban population growth and improvements of the road network. It concerns both small dairy producers and the industrial dairy subsector, which are connected by interdependent and balance of power relations all along the chain. Dairy farmers were surveyed from a technical and economic angle in various regions. Results show that this dairy development brings about major income inequalities among producer types, reflecting an unequal access to resources. Statistical data in the literature and interviews of actors of the Peruvian dairy chains allow to assess the stakes and limits of quality approaches in the small producers’ chain faced with industries. Finally, the article questions the impact of free-trade agreements in which Peru is involved with regard to the domestic dairy subsector, and concludes with political proposals to accompany dairy development.

Economic Feed Utilization for Dairy Buffalo Under Intensive Agricultural System

2010-02-01

Full Text Available The national strategies for the irrigated intensive agricultural system in developing countries should focus upon Producing less expensive milk from dairy buffaloes that, efficiently, utilize the limited expensive produced feed resources. Therefore, planning for the least cost feeds combination is the most recommended approach to keep buffalo milk price at a competitive level and being low enough to make milk available for the major proportion of the low-income households, particularly “Vulnerable Groups”. Estimation of the least cost feed ration combination of the limited expensive feed resources were conducted from a recent farm survey of the dairy buffalo performances and the feed use pattern in Egypt. The estimated average production elasticity of fodder, concentrate feeds mix and straw, implies that their shares in generated buffalo milk income are 41.7%, 35%, and 23.3%, respectively.. The response of the human labor was of negative direction and statistically insignificant. This means that the labor used per dairy buffalo was beyond the economic level, that reflects the excess farm-family labor involved in such activity, because they have almost nil opportunity income of off farm work. The other capital inputs have small positive effect on milk production, The average marginal return from milk per onedollar expenditure reached $.1.08 for fodder, and $ 1.04 for concentrated feed mix, i.e. it is feasible to expand the usage of fodder more than concentrates. The wheat straw has shown uneconomic efficiency. Therefore, it is recommended to limit its level in the ration. The least cost ration reduces feed cost of one ton of buffalo milk equivalent (4% fat by 22%. The less costs of production will strength the competition of domestic supply either against in the international export market or against the dumping policies followed by exporters to the domestic market.

2013-01-01

Full Text Available Phytate, the major storage form of phosphorus in plant seeds, can form insoluble complexes with minerals such as iron, zinc and calcium thus reducing their bioavailability. Phytase enzymes are often used to upgrade the nutritional quality of phytate-rich foods and feeds such as grains. The phytate-degrading activity of 43 lactic acid bacteria including isolates from commercial probiotic preparations, dairy products and type strains were measured. The phytate-degrading activity of bifidobacteria and lactobacillus isolates from pharmaceutical probiotics, dairy products and type strains were determined. The enzyme activity of probotic bacteria ranged between 1.1-5.4 mU and was strain not species specific. Phytase activity may thus be a useful additional attribute of probiotics to be used as food supplements.

Dairy products are colonized with three main classes of lactic acid bacteria (LAB): opportunistic bacteria, traditional starters, and industrial starters. Most of the population structure studies were previously performed with LAB species belonging to these three classes and give interesting knowledge about the population structure of LAB at the stage where they are already industrialized. However, these studies give little information about the population structure of LAB prior their use as an industrial starter. Carnobacterium maltaromaticum is a LAB colonizing diverse environments, including dairy products. Since this bacterium was discovered relatively recently, it is not yet commercialized as an industrial starter, which makes C. maltaromaticum an interesting model for the study of unindustrialized LAB population structure in dairy products. A multilocus sequence typing scheme based on an analysis of fragments of the genes dapE, ddlA, glpQ, ilvE, pyc, pyrE, and leuS was applied to a collection of 47 strains, including 28 strains isolated from dairy products. The scheme allowed detecting 36 sequence types with a discriminatory index of 0.98. The whole population was clustered in four deeply branched lineages, in which the dairy strains were spread. Moreover, the dairy strains could exhibit a high diversity within these lineages, leading to an overall dairy population with a diversity level as high as that of the nondairy population. These results are in agreement with the hypothesis according to which the industrialization of LAB leads to a diversity reduction in dairy products.

It has recently been reported that the rare sugar d-allulose has beneficial effects, including the suppression of postprandial blood glucose elevation in humans, and can be substituted for sucrose as a low-calorie food ingredient. To examine the applications of d-allulose in the dairy industry, we investigated the effects of d-allulose on the acid production of 8 strains of yogurt starter (Lactobacillus delbrueckii ssp. bulgaricus and Streptococcus thermophilus) and 4 strains of lactococci, including potential probiotic candidates derived from dairy products. Acid production by 2 L. delbrueckii ssp. bulgaricus yogurt starter strains in milk was suppressed by d-allulose, but this phenomenon was also observed in some strains with another sugar (xylose), a sugar alcohol (sorbitol), or both. In contrast, among the dairy probiotic candidates, Lactococcus lactis H61, which has beneficial effects for human skin when drunk as part of fermented milk, was the only strain that showed suppression of acid production in the presence of d-allulose. Strain H61 did not metabolize d-allulose. We did not observe suppression of acid production by strain H61 with the addition of xylose or sorbitol, and xylose and sorbitol were not metabolized by strain H61. The acid production of strain H61 after culture in a constituted medium (tryptone-yeast extract-glucose broth) was also suppressed with the addition of d-allulose, but growth efficiency and sugar fermentation style were not altered. Probiotic activities-such as the angiotensin-converting enzyme inhibitory activity of H61-fermented milk and the superoxide dismutase activity of H61 cells grown in tryptone-yeast extract-glucose broth-were not affected by d-allulose. d-Allulose may suppress acid production in certain lactic acid bacteria without altering their probiotic activity. It may be useful for developing new probiotic dairy products from probiotic strains such as Lactococcus lactis H61. Copyright © 2017 American Dairy Science

The objectives of this study were to quantify the effect of 16 ppm of dietary monensin on milk production and composition of dairy cows, and to investigate factors having a potential impact on this effect. Data were generated from a total of 3577 Holstein dairy cows (47 herds) in Quebec enrolled in a herd-level, randomized clinical trial investigating the effects of monensin supplementation. Milk production and composition data were collected from monthly dairy herd improvement (DHI) testing. Monensin increased milk production by 0.9 kg/cow/d in cows under 150 days in milk (DIM) (P < 0.05). Monensin decreased milk fat percentage by 0.18 percentage points during the whole lactation (P < 0.05). This decreasing effect was larger for component-fed cows (P < 0.05) and for cows being fed low levels of dietary physically effective particles (P < 0.05) when compared respectively to cows fed total mixed ration and cows fed high levels of dietary physically effective particles. The results of this study suggest that monensin influences milk production and milk composition of dairy cows, and that diet composition and feeding system influence those effects. PMID:20592825

This work proposes a novel approach for the reuse and the recovery of dairy wastes valuable components. Thermal coagulation was performed for dairy effluents and the main responsible fraction for the organic matter content (protein and fat) was separated. Dairy curds were prepared for the formulation of bacterial growth media. Protein, sugar, fat and fatty acids contents have been assessed. Samples treated at 100 °C exhibited marked improvement in terms of protein (25-50%) recovery compared to those treated at 80 °C. Fatty acid analysis revealed the presence of unsaturated fatty acids (mainly oleic acid) that are essential to promote Lactobacillus growth. Previously isolated and identified bacterial strains from dairy wastes (Lactobacillus paracasei, Lactobacillus plantarum, Lactococcus lactis and Lactobacillus brevis) were investigated for their ability to grow on the formulated media. All the tested lactic acid bacteria exhibited greater bacterial growth on the formulated media supplemented with glucose only or with both glucose and yeast extract compared to the control media. By reference to the commercial growth medium, the productivity ratio of the supplemented bactofugate (B) and decreaming (D) formulated media exceeded 0.6 for L. paracasei culture. Whereas, the productivity ratio of the supplemented B medium was greater than 1 compared to the control medium for all the tested strains. As for the supplemented D medium, its productivity ratio was greater than 1 compared to the control medium for both L. paracasei and L. plantarum strains. Copyright © 2018 Elsevier Ltd.

success at disseminating innovation. Farmers' preferred sources of information are their churches and organisations such as women's groups rather than scientists and government extension agents. Although peri-urban small-scale dairying can be identified as a largely market-orientated activity, it is clear that the risk-limiting, enterprise-optimising outlook of the small farmer frequently prevails. It must be recognised that the availability of cash, the main constraint and concern of most small-holder households, remains the major limiting factor to the adoption of technical change. It is equally clear that to achieve greater productivity and sustainability, greater investment, particularly in animal feed, is essential. Adaptive research must attempt to achieve a compromise between these two realities. In addition, the research must be carefully targeted from the outset at farmers and the groups and organisations that are positioned to influence farmers. This will require taking stakeholders into the project from the start. (author)

Caseins are widely used for species identification of dairy products. Isoelectric focusing (IEF) of para-κ-casein peptide is used as the official German method for the differentiation between caprine (isoform A) and ovine (isoform B) dairy products, based on their different isoelectric points. The discrimination between Greek goat and ewe dairy products using IEF has, however, been shown to be problematic because of the existence of the ewe isoform in milk from Greek indigenous dairy goats. This could be due to nucleotide polymorphisms within the goat κ-casein gene of Greek indigenous breeds, which alter the isoelectric point of the para-κ-casein peptide and lead to false positive results. Previous DNA analysis of the goat κ-casein gene has shown high levels of polymorphism; however, no such information is available for Greek indigenous dairy goats. Therefore, 87 indigenous dairy goats were sequenced at exon IV of κ-casein gene. In total, 9 polymorphic sites were detected. Three nonsynonymous point mutations were identified, which change the isoelectric point of the goat para-κ-casein peptide so that it appears identical to that of the ewe peptide. Ten composite genotypes were reconstructed and 6 of them included the problematic point mutations. For the verification of genetic results, IEF was carried out. Both goat and ewe patterns appeared in the problematic genotypes. The frequency of these genotypes could be characterized as moderate (0.23) to high (0.60) within Greek indigenous breeds. However, this is not an issue restricted to Greece, as such genotypes have been detected in various non-Greek goat breeds. In conclusion, IEF based on the official German method is certainly inappropriate for ovine and caprine discrimination concerning Greek dairy goat products, and consequently a new method should be established.

The Irish agricultural policy 'Food Harvest 2020' is a roadmap for sectoral expansion and Irish dairy farming is expected to intensify, which could influence the environmental and economic performance of Irish milk production. Evaluating the total environmental impacts and the real cost of Irish milk production is a key step towards understanding the possibility of sustainable production. This paper addresses two main issues: aggregation of environmental impacts of Irish milk production by monetization, to understand the real cost of Irish milk production, including the environmental costs; and the effect of the agricultural policy 'Food Harvest 2020' on total cost (combining financial cost and environmental cost) of Irish milk production. This study used 2013 Irish dairy farming as a baseline, and defined 'bottom', 'target' and 'optimum' scenarios, according to the change of elementary inputs required to meet agricultural policy ambitions. The study demonstrated that the three monetization methods, Stepwise 2006, Eco-cost 2012 and EPS 2000, could be used for aggregating different environmental impacts into monetary unit, and to provide an insight for evaluating policy related to total environmental performance. The results showed that the total environmental cost of Irish milk production could be greater than the financial cost (up to €0.53/kg energy corrected milk). The dairy expansion policy with improved herbage utilization and fertilizer application could reduce financial cost and minimize the total environmental cost of per unit milk produced.

Dairy proteins are amenable to structural modifications induced by high temperature, shear, and moisture; in particular, whey proteins can change conformation to new unfolded states. The change in protein state is a basis for creating new foods. The dairy products, nonfat dried milk (NDM), whey protein concentrate (WPC), and whey protein isolate (WPI) were modified using a twin-screw extruder at melt temperatures of 50, 75, and 100 degrees C, and moistures ranging from 20 to 70 wt%. Viscoelasticity and solubility measurements showed that extrusion temperature was a more significant (P extruded dairy protein ranged from rigid (2500 N) to soft (2.7 N). Extruding at or above 75 degrees C resulted in increased peak force for WPC (138 to 2500 N) and WPI (2.7 to 147.1 N). NDM was marginally texturized; the presence of lactose interfered with its texturization. WPI products extruded at 50 degrees C were not texturized; their solubility values ranged from 71.8% to 92.6%. A wide possibility exists for creating new foods with texturized dairy proteins due to the extensive range of states achievable. Dairy proteins can be used to boost the protein content in puffed snacks made from corn meal, but unmodified, they bind water and form doughy pastes with starch. To minimize the water binding property of dairy proteins, WPI, or WPC, or NDM were modified by extrusion processing. Extrusion temperature conditions were adjusted to 50, 75, or 100 degrees C, sufficient to change the structure of the dairy proteins, but not destroy them. Extrusion modified the structures of these dairy proteins for ease of use in starchy foods to boost nutrient levels.

Despite the ever-increasing number of patients with dementia worldwide, fundamental therapeutic approaches to this condition have not been established. Epidemiological studies suggest that intake of fermented dairy products prevents cognitive decline in the elderly. However, the active compounds responsible for the effect remain to be elucidated. The present study aims to elucidate the preventive effects of dairy products on Alzheimer’s disease and to identify the responsible component. Here, in a mouse model of Alzheimer’s disease (5xFAD), intake of a dairy product fermented with Penicillium candidum had preventive effects on the disease by reducing the accumulation of amyloid β (Aβ) and hippocampal inflammation (TNF-α and MIP-1α production), and enhancing hippocampal neurotrophic factors (BDNF and GDNF). A search for preventive substances in the fermented dairy product identified oleamide as a novel dual-active component that enhanced microglial Aβ phagocytosis and anti-inflammatory activity towards LPS stimulation in vitro and in vivo. During the fermentation, oleamide was synthesized from oleic acid, which is an abundant component of general dairy products owing to lipase enzymatic amidation. The present study has demonstrated the preventive effect of dairy products on Alzheimer’s disease, which was previously reported only epidemiologically. Moreover, oleamide has been identified as an active component of dairy products that is considered to reduce Aβ accumulation via enhanced microglial phagocytosis, and to suppress microglial inflammation after Aβ deposition. Because fermented dairy products such as camembert cheese are easy to ingest safely as a daily meal, their consumption might represent a preventive strategy for dementia. PMID:25760987

Pasture-based dairy systems use grazing to supply significant percentages of the dry matter intake of cows and heifers. Such systems vary from those for which pasture is used only as a supplemental feed for cows primarily fed a total mixed ration to those for which pasture is the primary source of dry matter for the herd. Cows that are optimal in a pasture system share many general characteristics with cows that are appropriate for a nonpasture system, including feed efficiency, maintenance of body condition, reproductive fitness, udder health, longevity, and the ability to adapt to various management systems. However, in such divergent feeding systems, the relative importance of various traits can differ. In pasture systems where cow nutrient demand intentionally coincides with seasonal forage availability, the focus of selection has emphasized fertility and other fitness traits, as well as yields of milk or milk components. Breeds or strains with higher yields of protein and fat typically have advantages in grazing systems that supply milk to solids-based or cheese markets. Holstein cows with high percentages of North American ancestry can work well in grazing systems that include supplemental concentrates or partial mixed rations, particularly if calving intervals are less restrictive. Crossbred cows can be selected for use in specific grazing systems as well as for specific milk markets, with the added advantage of heterosis. Breeds and crosses with high fertility are important for seasonal breeding and calving. The ability of cattle to both milk and maintain sufficient body condition for reproduction is important for any dairy production system but is critical in a seasonal system. Dairy farms that depend on pasture for most of dry matter for cows typically have lower production per cow than nongrazing dairies but have the potential to be economically competitive because of lower operating and overhead costs. Although the principles of selection are similar
