Book Description
Three trials were conducted to assess the influence of the barley silage particles as a source of effective fiber in total mixed rations for ruminants. Trial one determined the effective fiber characteristics of barley silage at different theoretical cut length; short barley silage (SBS) = 4.68 mm and long barley silage (LBS) = 18.75 mm in a replicated switch back design using six steers fitted with rumen fistulae to measure rumen fermentation patterns, kinetics, digestibility of cell wall constituents. In the second trial, four steers fitted with rumen fistulae in a 4 x 4 Latin square design were used to study the effect of barley silage particle size and concentrate level on the above variables. The third trial used eight multiparous lactating dairy cows in a replicated 4 x 4 Latin squire design to determined the effect of barley silage particle size and concentrate level on eating behavior, milk production and composition. In the first trial, feeding SBS increased DMI and total tract digestibility of DM, NDF and ADF compared with LBS. Mean ruminal pH was lower for steers fed SBS than those fed LBS but pH range was higher (P

Metabolic Modifiers
Author: National Research Council
Publisher: National Academies
ISBN: 0309049970
Category : Technology & Engineering
Languages : en
Pages : 94
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.
