Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive volume examines the interrelationships of nitrogen and energy nutrition of ruminants. It provides exhaustive coverage of basic concepts, applications, and new research developments.Rumen microbial activity is emphasized. The author, an expert in animal nutrition, discusses new systems of determining dietary energy requirements, the effect of processing feedstuffs, and stress factors. He reviews the availability of nutrients in grains, distillers' grain residues, oilseed meals, molasses, silages, pastures, crop residues, and aquatic plants. Growth stimulants, nutritional management of ruminants in feedlots and pastures, and the value of feed additives are also among the topics considered.The scope of coverage provided by this volume will make it the leading reference for teachers, researchers, consultants, livestock producers, feed manufacturers, and all others who are involved in ruminant feeding and nutrition.From the Preface: This volume covers research on various nitrogen and energy feedstuffs and defines terminology commonly utilized in nitrogen and energy nutrition. The utilization of nitrogen and energy in oilseed meals, fish meals, cereal grains, distillers' residues, molasses, silages, grasses, hays, crop residues, animal waste, and nonprotein nitrogen sources is discussed. Details are given on development and utilization of net energy systems, systems for balancing total nitrogen, and nonprotein nitrogen with total digestible nutrients (TDN) or energy components of ruminant diets. Discussions are presented on metabolism, feedlot, milking, and grazing trials. Growth stimulants, processing of feedstuffs, type of animal, and environmental and management factors that affect feed intake, growth, feed efficiency, and quality of product are reviewed.Emphasis is given to the contributions of ruminal microbes in upgrading forage and nonprotein nitrogen sources to higher-quality bacterial protein, as well as their ability to downgrade high-quality protein and waste nitrogen when protein is fed in excess of microbial needs. Research is presented on means to increase bypassing of the rumen to prevent nitrogen wastage when ruminants are fed concentrate diets. Contributions of ruminal microbes in utilizing cellulosic materials as lignocellulose and hemicellulose as well as starch and other carbohydrates are discussed.
Download or read book Nitrogen Utilization in Dairy Cattle Consuming Rations Containing Corn Milling Co products written by Amanda Mary Gehman and published by . This book was released on 2009 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased demand for products synthesized from corn starch, such as ethanol and high fructose corn syrup, has resulted in an increased supply of corn milling co-products, such as wet distillers grains with solubles (WDGS ) and wet corn gluten feed (WCGF). These products differ in chemical and physical properties from corn as well as common forages. While the effects of feeding corn milling co-products on intake and milk production in lactating dairy cattle has been researched, effects on nitrogen utilization have not been studied in detail. Two experiments were conducted to study the effects of feeding WDGS and WCGF on digestibility, ruminal microbial protein synthesis, and nitrogen excretion. ^ Experiment 1 examined the potential complementary nutritional effects of feeding WDGS and WCGF together and to explore the means of maximizing total inclusion of co-products in rations for dairy cattle. Total tract N digestibility and microbial protein synthesis increased for the ration containing WDGS and WCGF. Fecal N excretion did not increase, while urinary N increased compared the control; however, manure N excretion was similar. Treatments did not differ in 4% fat-corrected milk. Results suggest that dairy rations can be balanced to include a 30% blend of WDGS and WCGF while maintaining similar manure N excretion and milk production as compared to a ration without co-products. ^ Experiment 2 examined the effects of forage type when feeding high levels of WDGS. Lactating cows were fed rations varying in levels of WDGS (0 or 25% DM) and forage type (corn silage or alfalfa silage). Microbial protein synthesis increased for rations containing WDGS regardless of forage type. Fecal N excretion was not different among treatments, but compared to a zero control, urinary and manure N was reduced with WDGS. Both the inclusion of WDGS and alfalfa silage improved 4% fat-corrected milk production. This research demonstrated rations can be formulated to contain 25% WDGS and result in reduced N excretion regardless of forage type, while improving milk production.^

This book was released on 2018-03-13 with total page 31 pages. Available in PDF, EPUB and Kindle. 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 Nutrient Utilization Lactational Performance and Profitability of Dairy Cows by Feeding Protein Supplements in High Forage Lactation Diets written by Kathryn Neal and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the increasing cost of soybean meal and concerns of excess N being excreted into the environment, new protein supplements have been developed. Two products that have shown potential in increasing N utilization efficiency are slow release urea (SRU; Optigen) and ruminal escape protein derived from yeast (YMP; DEMP). The objective of this study was to assess the effects of feeding these 2 supplements in high-forage [(54% of total dietary dry matter (DM)] dairy diets on nutrient utilization, feed efficiency, lactational performance of dairy cows, and their impacts on income-over feed costs. Twelve multiparous dairy cows were used in a triple 4 ©7 4 Latin square design with one square consisting of ruminally cannulated cows. Treatments included: 1) control, 2) SRU-supplemented total mixed ration (TMR, SRUT), 3) YMP-supplemented TMR (YMPT), and 4) SRU and YMP-supplemented TMR (SYT). The control consisted only of a mixture of soybean meal and canola meal (SBMCM) in a 50:50 ratio. The SRU and the YMP were supplemented at 0.49% and 1.15% DM, respectively. The experiment consisted of 4 periods lasting 28 d each (21 d of adaptation and 7 d of sampling). Cows fed YMPT and SYT had decreased intake of DM, and all supplemented treatments had lower crude protein intake compared to those fed the control. Milk yield tended to have the greatest increase in YMPT compared with the control (41.1 vs. 39.7 kg/d) as well as a tendency for increased milk fat and protein yields. Feed efficiencies based on yields of milk, 3.5% fat-corrected milk, and energy-corrected milk increased at 10-16% due to protein supplementation. Cows fed with protein supplements partitioned less energy toward body weight gain, but tended to partition more energy toward milk production. Efficiency of use of feed N to milk N increased by feeding SRUT and YMPT, and milk N-to-manure N ratio increased in YMPT. Cows fed SRUT or YMPT tended to improve income-over feed costs. Overall results from this experiment indicate that replacing SBMCM with SRU and YMP in high-forage dairy diets can be a good approach to enhance dairy profitability through improved nutrient utilization efficiencies by lactating dairy cows.
