This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cattle temperament has historically influenced selection decisions due to ease of handling. However, temperament may also influence economically relevant traits. The purpose of this study was to investigate relationships between temperament, Bovine Respiratory Disease (BRD) incidence, and resulting carcass merit in feedlot steers. Across a two year period, 2,870 crossbred steers were shipped from a single ranch source to a feedlot. At the time of feedlot placement, as well as at the time of reimplantation, temperament was measured via chute score (CS) and exit velocity (EV). Blood samples were taken upon arrival to the feedlot to determine circulating concentrations of interleukin 8 (IL-8) and cortisol, both of which are involved in immune function. Performance traits, including weight and gains, were measured at feedlot placement (d 0), reimplantation (d 73-100), and again 59 to 70 days later. Recorded carcass data included HCW (HCW), USDA yield grade (YG), marbling score (MS), ribeye area, and lung scores. Phenotypic statistical analysis was performed with SAS statistical software (SAS Inst., Inc., Cary, NC) and genetic parameters were estimated using ASREML (Ver. 3.0, VSN International, Ltd., Hemel Hempstead, UK). The pedigree file included records of 7,177 animals with up to 7 generation of pedigree. Contemporary group (CG, n=11) included initial ranch unit, date of arrival to the feedlot, feedlot pen, and processing dates. Fixed effects included in the model were pre-feedlot entry BRD treatment and CG. Cattle with higher CS at placement subsequently had more BRD incidence (P

Book excerpt: Intensive Beef Production, Second Edition focuses on the technologies, methodologies, and approaches involved in beef production, including genetics, breeding, feed utilization, fertility, and growth efficiency. The publication first elaborates on the beef market, carcass composition and quality, and genetic improvement. Discussions focus on breeding systems, correlation between traits, selection for meat production in dairy cattle, body weight and composition, carcass evaluation, consumption, and international trade. The book then examines genotype, physiology of digestion and feed utilization, and beef calf production, including factors controlling feed intake, nitrogen utilization, artificial methods of augmenting fertility, birth weight, calf mortality, and weaning weight. The text takes a look at dairy calf production, breed, sex, and hormones, and growth and efficiency. Topics include energy concentration and source, grain processing, protein, antibiotics, vitamins, growth mechanisms, breed, hormones, breed suitability, and mortality and disease. The book is a valuable reference for researchers interested in beef production.
