Download or read book Effects of lipids from various oilseeds supplied in different forms on ruminal biohydrogenation of fatty acids in vitro and on milk production and milk fatty acid composition of dairy cows written by Achim Hoffmann and published by Cuvillier Verlag. This book was released on 2017-10-24 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary lipid supplements in ruminant diets, whether from various natural sources or supplements such as rumen protected lipids, have a long history and are widely used. The main reasons for using these supplements include an increased energy density of dairy cow diets, e.g. in the early stage of lactation (Clapperton and Steele, 1983). Moreover, reproductive parameters might are affected as well by using lipid supplements, either indirectly by changes in the energy balance of cows or directly due to the effects of certain fatty acids (FA) on reproductive organs and processes (Leroy et al., 2014).

Download or read book Milk and Dairy Products in Human Nutrition written by Young W. Park and published by John Wiley & Sons. This book was released on 2013-04-09 with total page 1063 pages. Available in PDF, EPUB and Kindle. Book excerpt: Milk is nature’s most complete food, and dairy products are considered to be the most nutritious foods of all. The traditional view of the role of milk has been greatly expanded in recent years beyond the horizon of nutritional subsistence of infants: it is now recognized to be more than a source of nutrients for the healthy growth of children and nourishment of adult humans. Alongside its major proteins (casein and whey), milk contains biologically active compounds, which have important physiological and biochemical functions and significant impacts upon human metabolism, nutrition and health. Many of these compounds have been proven to have beneficial effects on human nutrition and health. This comprehensive reference is the first to address such a wide range of topics related to milk production and human health, including: mammary secretion, production, sanitation, quality standards and chemistry, as well as nutrition, milk allergies, lactose intolerance, and the bioactive and therapeutic compounds found in milk. In addition to cow’s milk, the book also covers the milk of non-bovine dairy species which is of economic importance around the world. The Editors have assembled a team of internationally renowned experts to contribute to this exhaustive volume which will be essential reading for dairy scientists, nutritionists, food scientists, allergy specialists and health professionals.

Book excerpt: Consumers are increasingly aware of the connection between diet and heath, and the nutrient composition of foods is required to appropriately assess dietary intake and establish recommendations. The last survey of U.S. commingled milk was in 1984 and since then, substantial improvements in the analytical techniques of fatty acids (FA) have allowed for a more detailed isomer profile. Milk contains bioactive FA shown to have potent anticarcinogenic and antiatherosclerotic properties, such as conjugated linoleic acid (CLA) and omega-3 FA. The first objective was to evaluate current FA composition of retail milk in the U.S. to include 1) regional and seasonal differences, and 2) differences among unlabeled conventional milk and milk labeled rbST-free or organic. While statistical significance was reported for most FA by geographic region and season as well as among label type, numerical differences were minor, having little or no public health relevance. These results indicate that the increased use of total mixed rations, lipid supplements and by-product feeding must be well established across all geographic regions and seasons. In addition, when combined with previous analysis, results indicate that all milk is wholesome and nutritious regardless of production management practice. Milk FA composition is highly affected by diet, thus the second objective was to naturally enhance CLA and omega-3 FA in milk fat through the use of dietary lipid supplements. The first two studies utilized soybean oil or linseed and fish oil to enhance milk bioactive FA, with the inclusion of a high dose of dietary vitamin E to mitigate diet-induced milk fat depression (MFD) caused by lipid supplementation. CLA content in milk fat markedly increased with lipid supplementation, however vitamin E had no effect. Lastly, a genetically-modified soybean oil enhanced with stearidonic acid (SDA) was fed and resulted in impressive increases of omega-3 FA in milk fat. Human consumption of omega-3 FA are well below dietary recommendations, and SDA enhanced milk may serve as a novel dietary source of these FA. Methods to enhance bioactive FA in milk fat continue to be investigated, thus establishing the potential for improved human health through the consumption of dairy products.

Available in PDF, EPUB and Kindle. Book excerpt: Among the major components of human diet, edible fats and oils are typically produced through various forms of technological manipulation of naturally available starting material. It is also generally recognized that dietary fat, namely the type and amount, playa significant role in modulating the health stat~s of large population groups in econ omically advanced countries, and that, more specifically, the onset and progression of a number of diseases of wide incidence and large socio-economical relevance, such as hyperlipidaemias, diabetes, hyper tension, are significantly affected by dietary fats. Associations operating in public health preventive programs and clinical associations in affluent countries have recommended changes of dietary habits and especially of fat consumption in the whole community. Among the parameters to be modified of special relevance are the re duction of total fat, of saturated fatty acids and cholesterol intake and to increase the amount of unsaturated fatty acids. It is, however, becoming more and more evident that each member of the complex fatty acid moiety of our diet may playa different role from a nutritional point of view. This is particularly true for the highly unsaturated compounds belonging to the two metabolic series n-6 and n-3, contained in high concentrations in vegetable oils and in lipids from marine animals respectively, as well as for oleic acid, contained in high concentrations in olive oil.

Download or read book Improving the Fat Content of Foods written by C Williams and published by Woodhead Publishing. This book was released on 2006-01-31 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: As health problems such as obesity, heart disease and diabetes increase in many developed and developing countries, the food industry has come under mounting pressure to improve the nutritional quality of its products. Particular attention has focused on the health problems associated with saturated fats in food and on the potential health benefits of increasing monounsaturated and polyunsaturated fat content. Summarising key research in this field, this important collection reviews both the influence of dietary fats on health and practical strategies for improving the fat content of food products. Part one reviews the evidence on the links between dietary fats and health. There are chapters on the links between saturated fatty acid intake, obesity, coronary heart disease, diabetes and cancer, as well as the health benefits of monounsaturated fats, polyunsaturated fatty acids (PUFAs) and conjugated linoleic acids (CLAs). Part two then discusses ways of reducing saturated fatty acids in food. It includes chapters on the role of lipids on food quality and ways of gaining consumer acceptance of low-fat foods, as well as chapters on improving fatty acid composition in dairy products and milk and the use of fat replacers. The final part of the book reviews ways of using polyunsaturated and other modified fatty acids in food products. It includes chapters on developing and using PUFAs as functional ingredients and ways of improving the sensory quality of products incorporating modified fats. With its distinguished editors and international team of contributors, Improving the fat content of foods is a standard reference for nutritionists and product developers in the food industry. Reviews the influence of dietary fats on health Investigates practical strategies for improving the fat content of food products Discusses improving the fat content of foods whilst maintaining sensory quality

Download or read book Investigating the Behavior of Fatty Acids and Fat Supplements in the Rumen of Dairy Cattle and the Effects on Milk Fat Production written by Reilly Pierce and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary fat is an important component on the diets of lactating dairy cattle. Concentration of dietary fat can be increase by feeding oilseeds or enriched fat supplements which allows cattle to partition energy differently which can lead to increases in milk fat concentration, milk fat yield, or milk yield. One common oilseed fed to dairy cattle is cottonseed, as it is high in fiber but also relatively high in fat compared to other common feedstuffs. Fat supplements are very high in fat (>95%) but are more expensive so dairy producers often strike a balance and may feed both fat supplements and oilseeds to dairy cattle. The first objective of this thesis was to investigate the effects of cottonseed on milk production in dairy cattle. Previous research feeding cottonseed fed inclusion rates of cottonseed in excess of 15% of dry matter intake (DMI), but cattle were producing less milk and consuming less so therefore, the actual mass of the cottonseed consumed may not be as high as contemporary dairy cattle. This thesis fed cottonseed at up to 9.9% of DMI and found that cottonseed inclusion into the diets of multiparous cattle did not affect milk yield or milk composition but led to a decrease in DMI indicating that it could be safely fed to mature cows. In primiparous cattle, cottonseed inclusion induced milk fat-depression, indicating that the level of unsaturated fatty acids in the diet was greater than the biohydrogenation potential of the ruminal microbes of these animals. The second part of this thesis was to examine the effects of increased concentrations of an unsaturated fatty acid (cis-9 C18:1; oleic acid) in a prilled fat supplement on the milk production and milk composition in dairy cows. Previous research suggests that oleic acid may increase digestibility of dietary fatty acids and consequently increase the amount of preformed fat for milk fat synthesis. This experiment indicated that fat supplementation in multiparous cows may decrease milk yield and DMI but was no effect of increased levels of oleic acid on other production components in dairy cattle. Further investigation of the data collected for each half of the thesis is required to determine the effects on the respective methods of fat supplementation on fatty acid digestibility in lactating dairy cattle.
