This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In many pasture and rangeland scenarios, low-quality forages (6-8% CP) are the primary energy source for some portion of the year. At these times, energy is typically the first limiting nutrient to the ruminant. Low-quality forages are generally not limited in availability; however, the high cell wall content and reduced levels of CP prevent ruminants from being able to extract the harvested energy. Without provision of supplemental nutrients, the available energy may be inadequate to meet performance expectations. Protein supplementation during periods of inadequate forage quality has been observed to alleviate ruminal nitrogen deficiencies and increase forage utilization. Increased forage utilization translates into greater energy extraction allowing for increased animal performance. The first trial was conducted to evaluate the effects of utilizing non-protein nitrogen (a slow-release urea compared to urea) on intake and digestion of beef steers consuming low-quality bermudagrass hay. Steers were provided ad libitum access to a low-quality bermudagrass hay (7.3 % CP and were ruminally dosed once daily with either urea or slow-release urea (SRU) at levels to provide 0, 64, 128, or 192 mg of N/kg of initial BW per day. Additionally, steers were supplemented with glycerol at levels of 0 or 0.1% of initial BW per day. Total OMI and forage OMI (FOMI) increased quadratically (P
Book Synopsis Livestock Production and Climate Change by : Pradeep K Malik
Download or read book Livestock Production and Climate Change written by Pradeep K Malik and published by CABI. This book was released on 2015-04-22 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a changing climate, livestock production is expected to exhibit dual roles of mitigation and adaptation in order to meet the challenge of food security. This book approaches the issues of livestock production and climate change through three sections: I. Livestock production, II. Climate change and, III. Enteric methane amelioration. Section I addresses issues of feed quality and availability, abiotic stress (heat and nutritional) and strategies for alleviation, livestock generated nitrogen and phosphorus pollution, and approaches for harnessing the complex gut microbial diversity. Section II discusses the effects of climate change on livestock diversity, farm animal reproduction, impact of meat production on climate change, and emphasising the role of indigenous livestock in climatic change to sustain production. Section III deals with the most recent approaches to amelioration of livestock methane such as breeding for low methane emissions, reductive acetogenesis, immunization/vaccine-based concepts and archaea phage therapy.
Book Synopsis Nutrient Requirements of Beef Cattle by : Subcommittee on Beef Cattle Nutrition
Download or read book Nutrient Requirements of Beef Cattle written by Subcommittee on Beef Cattle Nutrition and published by National Academies Press. This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

Book Synopsis Nutritional Ecology of the Ruminant by : Peter J. Van Soest
Download or read book Nutritional Ecology of the Ruminant written by Peter J. Van Soest and published by Cornell University Press. This book was released on 2018-09-05 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982. Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy. Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships. Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.
Book Synopsis Effects of Supplemental Energy and Protein on Forage Digestion and Urea Kinetics in Beef Cattle by : Eric Arthur Bailey
Download or read book Effects of Supplemental Energy and Protein on Forage Digestion and Urea Kinetics in Beef Cattle written by Eric Arthur Bailey and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments quantified effects of supplemental protein and energy on forage digestion and urea kinetics in beef cattle. In experiment 1, energy treatments included: control, 600 g glucose dosed ruminally once daily, and 480 g VFA infused ruminally over 8 h daily. Casein was dosed ruminally once daily (120 or 240 g). Cattle (208 kg) had ad libitum access to low-quality hay (5.8% protein). Infusion of VFA decreased forage intake by 27%. Glucose decreased NDF digestibility. Microbial N flow was greater for 240 than for 120 g/d casein, but was not affected by energy. Retained N increased with casein supply. Urea-N entry rate (UER) and gut entry of urea-N (GER) were not affected by energy, casein, or interactions, but GER/UER was less when 240 rather than 120 g/d casein was provided. Compared to VFA, glucose tended to increase GER/UER. Glucose led to more microbial uptake of recycled urea than VFA. In these young calves, changes in N and energy supply did not greatly impact urea kinetics, likely because increased N was largely retained. In experiment 2, treatments included: 0 or 1.2 kg glucose, and 240 or 480 g casein. Cattle (391 kg) were fed low-quality hay (4.7% protein). Glucose reduced forage intake by 18%, whereas casein did not affect it, and depressed fiber digestion. Microbial N flow to the duodenum and retained N increased as casein increased, but neither was affected by glucose. Increasing casein increased UER 50%. Urinary urea-N increased as casein increased; moreover, GER numerically increased 25% as casein increased. GER/UER decreased as casein increased. Glucose decreased urinary urea, but did not change UER or GER. Microbial uptake of recycled urea was least for steers receiving 480 g/d casein with no glucose, reflecting that this treatment exceeded ruminal requirement for N. In these more mature steers, increases in N intake increased UER, reflecting that only small proportions of the increased N intake were retained. Thus, as steer maturity increased, UER and GER increased, likely because less N was retained. These studies demonstrate the influence of urea recycling in meeting N needs of cattle fed low-quality forage.

Book Synopsis Effect of Increasing Protein Supplementation on Intake and Digestion of Bermudagrass Hays of Divergent Quality by Beef Cattle by : Catherine Pomeroy Payne
Download or read book Effect of Increasing Protein Supplementation on Intake and Digestion of Bermudagrass Hays of Divergent Quality by Beef Cattle written by Catherine Pomeroy Payne and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bermudagrass (Cynodon dactylon (L) Pers.), one of the predominant forages in the southeastern US, varies in nutritive value in response to management and environmental factors. Beef cattle supplementation decisions are complicated by this variability. Therefore, our objective was to determine the effect of four protein supplementation levels (0, 82, 119 and 155 mg N/kg BW) on the utilization of three bermudagrass hays (5.6, 6.3, and 8.1 percent CP). Thirteen ruminally fistulated Angus x Hereford steers (BW = 330 plus/minus 19 kg) were used in a 13 x 4 incomplete Latin square design with 13 treatments. Treatments were arranged as a 3 x 4 factorial plus a control bermudagrass hay (10.8 percent CP). Hay was provided ad libitum and protein supplements were offered as range cubes once daily. Periods were 15 d with intake determinations made on d 10 through d 13 to correspond with fecal grab samples collected from d 11 through d 14. Acid detergent insoluble ash was used as an internal marker for determination of fecal output. Hay OM intake of unsupplemented steers increased linearly (P
Book Synopsis Understanding the Effect of Reduced Supplementation Frequency on Performance, Digestion and Metabolism of Stocker Cattle by :

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Supplements are often fed to stocker cattle on forage-based diets to improve animal performance. Delivery costs can make up a substantial portion of the cost of supplementation. Reducing supplementation frequency can reduce labor and equipment costs and therefore has the potential to increase profit. However, less frequent feeding requires feeding larger quantities of supplement at once and can increase the likelihood of negative associative effects of supplementation. Additionally, little is understood about the metabolic response of ruminants to large fluxuation in nutrient intake. A 50:50 blend of soyhulls and corn gluten feed is widely used by producers to supplement growing cattle. This blend is high in energy but low in starch. It also contains a moderate amount of protein, much of which is ruminally degradable. The purpose of this research was to determine the effect of reducing supplementation frequency of a soybean hull and corn gluten feed blend on performance, digestion, and concentrations of metabolites and hormonal growth regulators in blood of steers. In Experiment 1, growing steers consuming medium quality fescue hay were supplemented either daily, 3 times a week, or 2 times a week. Hay intake was decreased by reducing supplementation frequency but gains were not affected. As a result, the feed to gain ratio increased slightly with less frequent supplementation. In Experiment 2, six ruminally cannulated steers consuming medium quality fescue hay were used in a replicated 3 x 3 Latin square to determine the effect of supplement frequency (daily at 1% BW or on alternate days at 2% BW) on digestion and ruminal parameters. Reducing supplementation frequency decreased hay intake but did not affect digestibility of the diet. On the day of supplementation molar proportions both of propionate and butyrate in the rumen of steers supplemented on alternate days was increased compared to those supplemented daily. In Experiment 3, growing steers were individually.
