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.
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.

Download or read book Managing the Prenatal Environment to Enhance Livestock Productivity written by Paul L. Greenwood and published by Springer Science & Business Media. This book was released on 2010-04-27 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prenatal life is the period of maximal development in animals, and it is well recognised that factors that alter development can have profound effects on the embryonic, fetal and postnatal animal. Scientists involved in research on livestock productivity have for decades studied postnatal consequences of fetal development on productivity. Recently, however, there has been a surge in interest in how to manage prenatal development to enhance livestock health and productivity. This has occurred largely due to the studies that show human health in later life can be influenced by events during prenatal life, and establishment of the Fetal Origins and the Thrifty Phenotype Hypotheses. This book, Managing the Prenatal Environment to Enhance Livestock Productivity reviews phenotypic consequences of prenatal development, and provides details of mechanisms that underpin these effects in ruminants, pigs and poultry. The chapters have been divided into three parts: Quantification of prenatal effects on postnatal productivity, mechanistic bases of postnatal consequences of prenatal development and regulators of fetal and neonatal nutrient supply. Managing the Prenatal Environment to Enhance Livestock Productivity is a reference from which future research to improve the level of understanding and capacity to enhance productivity, health and efficiency of livestock in developing and developed countries will evolve. It is particularly timely given the development of molecular technologies that are providing new insight into regulation and consequences of growth and development of the embryo, fetus and neonate.
