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 2012-06-18 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.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the impact of strategic supplementation of straw-based diets with an energy-protein supplement and previously established residual feed intake (RFI) classification on beef cow performance (body weight, condition, feed intake, reproductive performance) in mid to late gestation and pre-weaning calf performance. Nutritional management regimens included nutrient adequate and deficient diets, along with examining frequency of supplementation to correct nutrient deficient diets. RFI classification was used to measure feed efficiency. RFI classification changes between years, and second and third trimesters were evaluated to establish influence of nutritional management regimen. Blood parameters were evaluated to assess effects of strategic supplementation in late gestation. The overall objective of the study was to evaluate how supplementation of low quality feed stuffs affects cow performance. The overall goal was to reduce the cost of production in beef cow-calf operations, with the use of more feed efficient cows and low quality feed stuffs.

This book was released on 2017 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of nutrition during late gestation and after insemination, as well as the effects of energy reserves on reproductive function of the beef female and subsequent growth and reproductive function of their offspring were investigated. The aims of this research were: 1) to evaluate how a change in nutritional intake immediately after insemination would affect pregnancy success and concentrations of hormonal mediators, IGF-I and progesterone, 2) to determine the influence that postpartum energy reserves have on embryo viability, early embryonic development, and embryo quality, and 3) to evaluate the impact that maternal protein supplementation of irrigated meadow grass hay during the last trimester of gestation has on cow BW and BCS, calf birth and weaning BW, conception rates of heifer offspring, and feedlot performance of steer offspring. Findings from Chapter III show that suppression in nutritional plane of heifers during the 21-d following AI has a negative impact on heifer performance, circulating concentrations of IGF-I, and AI pregnancy rates. Thus, it is biologically beneficial to ensure that heifers maintain their pre-breeding plane of nutrition during the 21-d following AI. Chapter IV presents evidence that cows with BCS 5.4 tend to produce more total embryos after a superovulation program compared to cows BCS 4.3. Additionally, peripheral concentrations of IGF-I were greatest in cows with a BCS 5.4, which may be an indicator of a more suitable environment in the uterus for further development of an embryo. In Chapter V, cows supplemented with protein during the last trimester of gestation had a greater BW gain and BCS change by calving time. Weaning BW of calves born to protein supplemented dams was greater when compared to calves from non-supplemented cows. There was a trend for pregnancy rates of heifers born supplemented dams to be 16 percentage points greater (95% vs. 79%). And although dam supplementation did not seem to affect intakes, gains, feed efficiency or carcass characteristics on the male progeny in this study, advantages have been observed other peer-reviewed research studies that support the concept that late gestation supplementation can have an impact subsequent progeny.

This book was released on 2013 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fall calving cows were used to determine the effects of protein supplementation on reproduction, and growth and carcass characteristics of calves. Cows were individually supplemented from mid-November to mid-March for four years with either a control diet (Con; 1.82 kg/d of 38 % CP) or low diet (L; 0.2 kg/d of 8% CP). During each year, cows were reassigned dietary treatments according to calving date and BCS, with half of Con and L cows remaining on the same diets as the previous year and the other half assigned to the other diet. Cows were exposed to bulls for 60 d beginning December 1. Statistical analyses were performed with a 2 x 2 factorial design with PROC GLM and PROC FREQ. Cows on Con diets lost less BW from November to January compared with L cows (-29.8 ± 2.8 and -49.7 ± 2.8 kg, P

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: 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.
