Book excerpt: Seminar paper from the year 2017 in the subject Veterinary medicine, Jimma University College of Agriculture and Veterinary Medicine, language: English, abstract: Objective of this review is focus on effect of feeding protected fat and protected protein on milk yield and its composition and how these nutrients are protected. Many researchers in this review investigate that the responses are highly dependent on the type of fat and protein supplement and the stage of lactation. A higher milk response was observed with saturated than with unsaturated fat supplements. Diet with added fat increase milk production compared with a control diet without added fat in cows. Feeding of bypass fat resulted in significant increase in milk yield and Fat Corrected Milk yield particularly in early lactation. The source of Protected fat are (origin (animal, plant, processed or whole oilseeds, calcium salts) and Cereal Grains such as corn, wheat, Barly, oil seeds, sun flower, cotton seed, soybeans and canola). The supplementation of protected protein in the diets of lactating animals increases the milk yield due to proportionate increase in the supply of amino acids to the host postruminally Milk yield in cows fed protected methionine for the whole experimental period was numerically higher than in cows of the other groups. However, the difference was not statistically significant .At the centeral high land of Ethiopia the Treatment of shredded wheat and barley straw with urea, molasses, salt and water prior to feeding is a technology that should be considered . Cows with excessive body tissue mobilisation at this stage may take up to 20 weeks to regain a positive energy balance status. Key words milk yield, composition ,protected fat , protein protected

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).

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.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability of nutritional supplements to generate responses in productive animals at different physiological stages, and their interaction with the particular gastrointestinal tract of ruminants have created the necessity to explore effects beyond productivity. Modulation of immune function and inflammatory processes, modifications of nutrient metabolism, and interactions with the ruminal microbial population are effects attributed to supplements that encouraged the formulation of the set of experiments described in this dissertation. The first experiment was designed to test the effects of arachidonic and docosahexaenoic acids supplemented in milk replacer for Holstein calves during the pre-weaning period on the immune system, lipid and glucose metabolism, and growth performance when animals underwent a vaccination protocol. Neither supplemental fatty acid source affected productivity, cytokine production, antibody production, or CD4 and CD8 cell proliferation. A treatment effect on glucose and NEFA plasma concentration was observed. Polyunsaturated fatty acids, mainly DHA, lowered glucose and NEFA levels compared to control; moreover, a dose effect was observed indicating that increasing amounts of PUFA decreased plasma glucose level. The second experiment tested the effects of Co carbonate (CoCarb) and Co glucoheptonate (CoGH) at different concentrations of Co on in vitro fermentation rate, fermentation end-products, and DM and NDF disappearance. Dry matter and NDF disappearance increased with CoGH relative to CoCarb at 1.0 ppm Co or less. CoCarb at> 3.0 ppm appeared to stimulate the biohydrogenation of long-chain fatty acids whereas CoGH had limited effects on this process. Finally, the third study evaluated responses to chromium propionate during peak lactation and interactions between chromium and rumen-protected lysine and methionine. Chromium propionate increased feed intake and tended to increase energy-corrected milk yield. Primiparous cows showed greater responses in feed intake and milk protein yield than multiparous cows. In this study, feeding chromium propionate near peak lactation increased feed intake and tended to increase productivity but no benefits of supplementing rumen-protected lysine and methionine were observed. Overall, nutritional supplements helped to regulate different biological functions in ruminants; their utilization is not always is feasible, but the results of these experiments provide guidance about effectiveness during different physiological situations.
