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.

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.

This book was released on 2016-06-16 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

Available in PDF, EPUB and Kindle. Book excerpt: Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A finishing experiment evaluated the effect of incremental supplemental rumen-protected lysine on beef cattle performance. All cattle were fed the same diet of high moisture corn, dried rolled corn, modified distillers grains plus solubles, corn silage, and supplement with inclusion levels of lysine ranging from 0 to 7 grams/day, in 1 g increments. Dry matter intake (P ≤ 0.04) and ADG (P ≤ 0.04) decreased linearly as supplemental lysine increased in the diet with no effect on final carcass adjusted feed efficiency (P ≥ 0.34). In the initial 64 days of the experiment, increasing lysine in the diet linearly decreased ADG (P ≤ 0.05) with a trend (P = 0.08) to linearly decrease feed efficiency. During the Optaflexx feeding period, DMI decreased linearly (P ≤ 0.01) with no effect on carcass adjusted ADG (P ≥ 0.51) or feed efficiency (P ≥ 0.34). Hot carcass weight tended to decrease linearly (P = 0.07) with no significant differences in carcass quality characteristics (P ≥ 0.20). In diets containing 15% modified distillers grains plus solubles, increasing supplemental lysine in the diet did not improve performance of finishing cattle. A finishing experiment evaluated the effect of a pistachio shell-sourced biochar on emissions and finishing performance of beef cattle. All cattle were fed the same diet of dried rolled corn, Sweet Bran (Cargill Wet Milling, Blair, NE), wheat straw, and supplement with biochar replacing 0.5% of dried rolled corn in the biochar treatment group. Eight pens of cattle were rotated as pairs through a 2-chambered emissions barn for 5 days for 8 consecutive weeks to analyze CH4 and CO2 produced by the cattle (2 measurement periods per pair). Biochar tended to increase CH4 emissions on a g/day basis (P = 0.09) with no effect on CH4 emissions as g/kg of DMI. There were no statistical differences in CO2 emissions as g/day or g/kg of DMI. Final performance, HCW, LM area, and marbling, did not differ between treatments (P ≥ 0.23). However, the control group tended to have improved 12th rib fat (P = 0.07) and yield grade (P = 0.06) compared to the biochar group. Including biochar at 0.5% of diet DM did not reduce eructed CH4 or respired CO2 and did not improve performance.

Download or read book Influence of Diet, Production Traits, Blood Hormones and Metabolites, and Mitochondrial Complex Protein Concentrations on Residual Feed Intake in Beef Cattle written by Michael Patrick Davis and published by . This book was released on 2009 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual feed intake (RFI) is the difference between measured feed intake and predicted feed intake of an animal. Intake prediction is computed from a regression of intake on gain and metabolic body weight. Residual feed intake is used as a measure of metabolic efficiency. As RFI increases, feed intake (FI) and feed conversion ratio (FCR) increase with no change in postweaning growth and body weight in steers. Identification and selection for lower RFI cattle would improve herd feed efficiency without influencing growth. Steer residual feed intake measured in the growing phase, is related to residual feed intake during the finishing phase. Animals with low residual feed intake in the growing phase had lower residual feed intake and improved feed efficiency in the finishing phase. Serum concentrations of glucose and mitochondrial function are related to metabolic efficiency and may differ between residual feed intake phenotypes. Serum concentrations of glucose at weaning were greater (P [lesser than] 0.05) in low (efficient) compared to high (inefficient) RFI steers. Mitochondrial complex protein concentrations I:II and I:III ratios were greater (P [lesser than] 0.05) in low extreme versus high extreme RFI steers. Diets varied in rumen undegradable protein content were used to determine impact of intestinal amino acid supply on growth performance. Increasing rumen bypass amino acids in no roughage diets during the growing phase tended (P [lesser than] 0.15) to influence ADG and FCR in the growing phase such that as rumen bypass amino acid level increased growth and feed efficiency improved in the growing phase. Steers fed post ruminal absorbable amino acid levels below that required for growth in growing phase tended (P [lesser than] 0.15) to have improved feed efficiency in the finishing phase. Also, during the growing phase as bypass amino acids increased subcutaneous and intramuscular fat deposition decreased in steers during the finishing phase. Feeding a level of bypass amino acids below optimum for growth to steers during the growing phase decreased (P [lesser than] 0.05) longissimus dorsi muscle area in steers during the finishing phase.
