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

Download or read book Effects of Protected Fat When Fed to Dairy Cattle and the Interaction Between Supplemental Fat and Antibiotics in Mixed Cultures written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fat is added to diets of lactating dairy cattle as an affordable method of increasing the amount of energy available to the animals. Unsaturated fatty acids are desirable end-products of milk production. However, their presence in the rumen can be toxic to ruminal bacteria, which will then decrease digestion. Unsaturated fatty acids are biohydrogenated into saturated fatty acids by specific bacteria in the rumen, which will decrease positive benefits associated with their consumption. Our first study evaluates the efficiency of calcium salts VALFEED 100M and VALFEED 200 in protecting unsaturated fatty acids from biohydrogenation in the rumen and also observes the effects of these 'protected fats' on lactation performance. Twenty-eight Holstein cows in early lactation were divided equally into four different treatment groups: 1) Control (with no supplemental fat); 2) Prilled fat; 3) Calcium salt of VALFEED 100M; 4) Calcium salt of VALFEED 200. Fat supplements were added to diets in place of corn in the concentrate mix at 3.2% of total dry matter intake. Cows were housed in free stalls equipped with Calan gates. The cows were fed twice daily, at 0800 and 1500 in amounts to allow ad libitum consumption. Weekly feed samples were taken and dried in order to calculate daily dry matter intake. Milk production was measured daily, and milk fat and protein content were analyzed at days 30 and 90. Body weights were taken at the beginning (day 0) and the end (day 90) of the trial. Prilled and VALFEED 100M fat supplements decreased (P 0.05) dry matter intake. Body weights were higher (P

Download or read book Protein and Amino acid nutrition written by Anthony Albanese and published by Elsevier. This book was released on 2012-12-02 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein and Amino Acid Nutrition describes the state of knowledge concerning the nutrition of proteins and amino acids. Topics range from the effect of some therapeutic agents on protein and amino acid nutrition, to species and age differences in amino acid requirements; utilization of D-amino acids; effect of proteins and amino acids on the growth of adult tissue in vitro; and amino acid requirements of animals and young adults. This volume is organized into 16 chapters and begins with an overview of the nutritional implications of the metabolic interrelationships of amino acids. The next chapters discuss experiments that tested the differences in amino acid requirements due to the differences in age and in species among animals, the biochemical individuality of amino acid requirements, and the utilization of dietary proteins. This book explains the synthesis of tissue proteins in relation to the essential amino acids; the link between food energy and nitrogen metabolism; and the use of the repletion method to measure the nutritive value of proteins, protein hydrolyzates, and amino acid mixtures. The final chapter discusses the nutritional needs of the older age groups. This book is intended for scientists, students, and researchers interested in human and animal nutrition.
Download or read book Responses in the Yield of Milk Constituents to the Intake of Nutrients by Dairy Cows written by Biotechnology and Biological Sciences Research Council (Great Britain). Technical Committee on Responses to Nutrients and published by Oxford University Press, USA. This book was released on 1998 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the energy and protein requirement systems for dairy cows currently used in Britain and presents a new approach, along with the outline of a model for its implementation. Current systems give little consideration to the responses of the animal to changes in the nutrient supply, or to interactions between dietary constituents in their effects on digestion and metabolism. Neither do they predict any effect on the partition of nutrient use between milk and body, or changes in the yields of milk fat, protein and lactose, which determine the commercial value of the milk. Therefore the systems, although not inaccurate, lack relevance to the current needs of UK milk producers. Models which embody concepts of nutrient supply and utilization are reviewed and their development as viable alternatives is considered. It is concluded that a new diet formulation system for dairy cows should aim to predict voluntary feed intake, the partition of nutrient use between milk production and tissue deposition, and the short and long-term of effects of nutrition on fat, protein and lactose yields. The physical and biological characteristics of the cow must also be recognized and incorporated into any model for response prediction. The report is also published in Nutrition Abstracts and Reviews - Series B: Livestock Feeds and Feeding. It is an authoritative review for advanced students, research workers and advisors in animal nutrition and in dairy science and technology.

Download or read book The Effects of Increased Metabolizable Protein in Fresh Dairy Cattle Throughout Peak Lactation written by Ethan Garrett Carder and published by . This book was released on 2016 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first few weeks after parturition in dairy cattle is a time marked by low, but increasing, feed intake and sharply increasing milk production. Because of low intake, nutrient density of the diet may need to be higher during this period to support increasing milk yields. We hypothesized that feeding higher levels of metabolizable protein (MP) and feeding supplemental rumen protected methionine and lysine would increase milk yield and protein concentration. The experiment consisted of 2 phases. Fifty-six Holstein cows (21 primiparous and 35 multiparous), starting at 3 DIM, were used in a randomized-block design with three diets (phase 1). At approximately 23 DIM, cows were moved into a free stall barn and fed the control diet (phase 2) to observe potential carry-over effects on production. Estimated DMI used in formulation was 17 kg/d. The treatments were control (16.5% CP, 10.9% RDP, 5.6% RUP, formulated for 25.1 kg/d MP allowable milk based on NRC model), high protein (HP; 18.5% CP,11.6% RDP, 6.9% RUP, 29.9 MP allowable milk), and amino acid treatment (MPAA; 17.5% CP, 10.5% RDP, 7.0% RUP 29.7 MP allowable milk). The MPAA diet included a proprietary spray-dried blood meal product (Perdue Agribusiness, Salisbury, MD) that provided 174 g/d and 62 g/d of dietary rumen-protected lysine and methionine, respectively, per the NRC model. The MP diet provided an estimated 156 g/d lysine and 45 g/d methionine, and the control diet provided 149 g/d lysine and 41 g/d methionine. Milk production and DMI were measured daily and milk was sampled for components on day 8, 15, and 20 during phase 1 and on day 30 during phase 2. Statistical model included parity, treatment, and week fixed effects, random effect of block, and cow as the experimental unit. In phase 1, treatment and treatment by parity interaction did not affect milk yield (33.6, 34.5, and 33.1 kg for Control, HP, and MPAA, respectively), DMI (17.8, 17.8, 18.5 kg/d for Control, HP, and MPAA, respectively), or milk protein yield (1.11 kg/d). Milk protein concentration was higher (3.30% vs 3.17% and 3.17%) for MPAA treatment as compared to the HP and control, respectively. Energy corrected milk (ECM) was higher (39.0 and 38.5 vs 35.2 kg) for MPAA and HP than for the control, respectively. MUN was higher (14.3 vs 12.7 and 11.5 mg/dl) for the Control compared to HP and MPAA. Plasma concentrations of Met were increased in HP and MPAA compared to the control, with MPAA being the highest. Plasma concentrations of 3-methylhistidine was decreased in HP and MPAA compared to the control. Production responses, for phases 1 and 2 combined, did not differ in HP and MPAA compared to the control. Overall, supplementing rumen-protected lysine and methionine with extra HP can increase ECM yield, milk protein concentration, and milk fat concentration and yield during the first 3 weeks of lactation.

Download or read book Animal Agriculture written by Fuller W. Bazer and published by Academic Press. This book was released on 2019-10-25 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management Addresses the urgent issue of sustainability in modern animal agriculture Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide
