Download or read book Feed Efficiency in the Beef Industry written by Rodney A. Hill and published by John Wiley & Sons. This book was released on 2012-09-11 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feed Efficiency in the Beef Industry provides a thorough and concise overview of feed efficiency in beef cattle. It frames the great importance of feed efficiency to the industry and details the latest findings of the many scientific disciplines that intersect and aim to improve efficient and sustainable production of nutritious beef. The vast majority of production costs are directly tied to feed. With increased demand for grains to feed a rapidly increasing world population and to supply a new demand for alternative fuels, feed costs continue to increase. In recent years, the negative environmental impacts of inefficient feeding have also been realized; as such feed efficiency is an important factor in both economic viability and environmental sustainability of cattle production. Feed Efficiency in the Beef Industry covers a broad range of topics ranging from economic evaluation of feed efficiency to the physiological and genetic bases of efficient conversion of feed to high quality beef. Chapters also look at how a fuller understanding of feed efficiency is leading to new selective breeding efforts to develop more efficient cattle. With wide-ranging coverage from leading international researchers, Feed Efficiency will be a valuable resource for producers who wish to understand the complexities, challenges, and opportunities to reduce their cost of production, for students studying the topic and for researchers and professionals working in the beef industry.

Book Synopsis Feedlot Cattle Nutrition and Metabolism by : Danilo Domingues Millen
Download or read book Feedlot Cattle Nutrition and Metabolism written by Danilo Domingues Millen and published by Frontiers Media SA. This book was released on 2023-07-31 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for high-quality beef has led to the necessity of including higher levels of cereal grains and its by-products into cattle diets. In this context, adequate nutrition of beef cattle involves knowledge of energy and nutrient requirements to define specific nutritional strategy. The evolution feeding strategies to feedlot cattle depends on advances related to ruminant metabolism, as well as to the ruminal microbiota. Furthermore, a continuous flow of knowledge development in feedlot cattle nutrition and metabolism is important, as new feeds, additives, or even new management approaches come up very often, and new scenarios will impact protein and energy metabolism, the ruminal microbiota, and also strategies to modulate ruminal fermentation to improve health and performance of feedlot cattle. Overall, the main goal of this Research Topic is to contribute with recent advances in feedlot cattle nutrition and metabolism, addressing studies related to the nutrition of high-performing ruminants, with a special emphasis on the feed efficiency, ruminal fermentation and animal performance. Furthermore, we are interested in different aspects of sustainability and efficiency. In other words, the goal is to attract studies that address such issues, both from a general perspective and in relation to specific domains. Hence, the integration of existing and current knowledge will help refine strategies to optimize the performance of feedlot cattle.

Book Synopsis Effects of Forage Level in Feedlot Finishing Diets on Carcass Characteristics, Sensory Attributes, and Palatability of Jersey Beef by : Emily Jeanine Arnett
Download or read book Effects of Forage Level in Feedlot Finishing Diets on Carcass Characteristics, Sensory Attributes, and Palatability of Jersey Beef written by Emily Jeanine Arnett and published by . This book was released on 2010 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Jersey cattle are recognized as being slower growing and having more yellow fat compared with other breeds, thus limiting the use of this breed for beef production. Because Jerseys are slower growing, they require additional time on feed to achieve acceptable market weights and yield acceptable hot carcass weights. Although Jerseys face challenges, the resulting product has other quality aspects that exceed the general beef population. Gaps in knowledge exist regarding the optimum forage level in finishing diets on growth performance, carcass characteristics, and beef palatability. The objective of this study was to evaluate the effects of forage level (12 vs. 24% sudangrass:alfalfa hay, DM-basis) in steam-flaked, corn-based finishing diets on carcass characteristics, palatability, and retail color stability of Jersey beef. Seventy-nine Jersey steers were blocked by weight and randomly assigned one of the following treatments for a 385-d trial period: Jersey low- 12% (JL; n = 38) or Jersey high- 24% (JH; n = 39) forage, DM-basis. Forty-eight hours postmortem (PM), strip loins were removed, vacuum-packaged, and aged at 3°C for 18 d PM. Following the aging period, steaks from the longissimus muscle were sliced, vacuum-packaged, and frozen ( -20°C) until analyzed. Steers fed the low forage diet had greater (P 0.05) backfat and tended to have greater dressing percent compared to steers fed the high forage diet. Live weight, HCW, LMA, and USDA Yield Grade were not affected (P 0.05) by forage level. Steers fed the low forage diet on average tended to bring a 6% greater value ($63.73 more per head) compared to steers fed the high forage diet. Objective color (L*, a*, b*) measurements decreased (P

Book Synopsis Quality and Grading of Carcasses of Meat Animals by : S. Morgan Jones
Download or read book Quality and Grading of Carcasses of Meat Animals written by S. Morgan Jones and published by CRC Press. This book was released on 2020-07-24 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three main factors affect the quality and composition of meat in farm animals. Production conditions determine the composition of the meat, while marketing and postmortem periods have a major bearing on the visual appearance and ultimate eating experience for the consumer. It is often difficult to compare research results from different countries since meat quality is assessed by a wide variety of procedures. Quality and Grading of Carcasses of Meat Animals reviews the development of commercial grading or classification schemes on a world-wide basis, and it provides a broad outline of the most common subjective and objective procedures for the assessment of meat quality. The book provides reviews on: Ante- and post-mortem effects on meat quality Reducing fatness in meat animals Prediction of carcass composition and meat quality World carcass and grading systems Electronic identification of animals
Book Synopsis Feeding Soybeans as a Source of Protein and Fat in Grow-finish Rations for Feedlot Steers by : Eugene Edward Deane Felton
Download or read book Feeding Soybeans as a Source of Protein and Fat in Grow-finish Rations for Feedlot Steers written by Eugene Edward Deane Felton and published by . This book was released on 2002 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybeans (SB) are readily available throughout the Midwest and are not commonly considered a feed ingredient for beef cattle. Soybeans, especially those that have been heat treated, have been used quite extensively in dairy and forage rations with few negative results being elicited. Previous work has suggested that SB improve growth performance and enhance ruminant product quality. Data on the effects of feeding raw SB on growth performance and carcass quality is limiting. A series of experiments were conducted to determine the responses of feeding SB to finishing steers as a source of dietary protein and fat. The first two studies involved feeding increasing levels of whole raw soybeans (WRS) to heavyweight finishing steers and determining responses to increased inclusion levels on performance and carcass quality. It was noted with feeding WRS, growth was delayed during roughly the first half of both studies and rebounded during the second half with little effect on any carcass characteristics. Feed efficiency was improved with WRS feeding by affecting intake and/or growth. In these first two studies, two different cattle types were used. In the first study large-frame continental type steers were used, where as smaller-framed English type steers were used in the second. In the study with the large-framed steers, marbling scores were not as uniform as they were in the second and it appeared that feeding WRS pushed a greater number of steers into higher quality grades. This effect was not observed for the second study. If the improvement in marbling scores were real, we speculated that this was a result of the additional dietary fat being fed with the feeding of WRS. A third experiment was conducted reevaluating the large-framed steer model and investigated the use of different sources of dietary fat. Sources were normal and high oleate SB and choice white grease. Fat addition improved feed efficiency, decreased feed intake and improved marbling scores by one-fourth of a marbling score grade. Source of fat did alter fatty acid and tocopherol composition of longissimus muscle and fatty acid composition of subcutaneous and perinephric fat. Lastly, to determine the effects of roasting and grinding of WRS on rumen fermentation, digestive function and blood metabolites a study using cannulated steers was conducted. Soybeans increased digestibility of dietary CP, OM, DM and increased protein fermentation end-products. Soybeans decreased liquid passage rate and increased the microbial contribution to duodenal protein and fat flow. Soybeans altered plasma and blood cell fatty acid profiles and increased circulating plasma levels of fatty acids and cholesterol. Treatment response differences were detected for processed vs. unprocessed soybeans but these differences were small.

Book Synopsis Metabolic Modifiers by : National Research Council
Download or read book Metabolic Modifiers written by National Research Council and published by National Academies. This book was released on 1994-02-01 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.
