Book Description
Effect of winter growing program on finishing performance, body composition, carcass merit, organ mass and oxygen consumption of beef steers was investigated. A total of 260 steers were utilized for the experiment. Four steers were randomly selected as an initial harvest group. Remaining steers were blocked by weight and randomly allotted to one of four treatment groups: (1) ad libitum fed high-concentrate diet (CF); (2) grazed on wheat pasture (WP); (3) fed a sorghum silage-based growing diet (SF); or (4) program fed a high-concentrate diet (PF). Steers in the WP, SF, and PF groups were managed to achieve approximately equal rates of BW gain. After 112 d steers in the WP, SF, and PF treatments were adapted to a high-concentrate diet for finishing. Steers from all treatment groups were harvested at a backfat of 1.27 cm. In addition, six steers from each treatment group were randomly selected for harvest at the end of the growing and finishing phases. During the finishing phase DMI was greater ( P

Book Description
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.

Book Description
'Feed efficiency in swine' has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.
