Book excerpt: Excerpt from Breeding Better Beef Cattle Through Performance Testing Performance testing offers beef cattle breeders a way of discovering and measuring differences among animals in their inherited abilities to grow rapidly, mature early, use feed efficiently, develop the' kinds of carcasses that are preferred by packers and consumers, and reproduce regularly. Thus, close attention to performance can give cattlemen the means of improving their herds and their profits. Research has demonstrated a high degree of heritability of several of these traits in beef cattle. Also, research has shown that when cattle are kept under nearly equal conditions and their performance records are adjusted for known environmental differences, genetically superior animals can be identified. Herd improvement based on records of performance tends to be permanent. Each time performance records are exploited ln breeding for a new generation, an increment of productivity, quality, or both is added to the herd. Substantial herd improvement can be made in as few as 10 to 20 years. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: The 1983 International Stockinen's School Handbooks include more than 200 technical papers presented at this year's Stockmen's School-sponsored by Wlnrock International-by outstanding animal scientists, agribusiness leaders, and livestock producers expert in animal technology, animal management, and general fields relevant to animal agriculture. The Handbooks represent advanced technology in a problem-oriented form readily accessible to livestock producers, operators of family farms, managers of agri-buslnesses, scholars, and students of animal agriculture. The Beef Cattle Science Handbook, the Dairy Science Handbook, the Sheep and Goat Handbook, and the Stud Managers' Handbook each include papers on such general topics as genetics and selection; general anatomy and physiology; reproduction; behavior and animal welfare; feeds and nutrition; pastures, ranges, and forests; health, diseases, and parasites; buildings, equipment, and environment; animal management; marketing and economics (including product processing, when relevant}; farm and ranch business management and economics; computer use in animal enterprises; and production systems. The four Handbooks also contain papers specifically related to the type of animal considered

Available in PDF, EPUB and Kindle. Book excerpt: Cornell All Forage Fed Bull Test (CAFFBT) was initiated to evaluate growth performance of young beef bulls. With improved genetics developed for forage production, progeny of these selected bulls can be brought to market sooner, and improved feed efficiency obtained through breeding of these sires may reduce cow herd feed costs. The CAFFBT was conducted for four years at the Cornell University Ruminant Center in Dryden, NY. Live weights and body condition score (BCS) were recorded every 28 days. Initial and final hip heights were measured and age at measurement were used to calculate frame score (FS). Carcass ultrasound (US) was conducted to measure rump fat thickness, rib fat thickness, ribeye area and intramuscular fat. Breeding soundness exams were performed to gauge the breeding potential. Each year had a warm-up period prior to start. Test length was 112 days for years 1, 2, and 4, and 140 days for year 3. Year one of the test evaluated 13 bulls fed alfalfa hay. The average weight gain was 1.0 kg/day. In year two, 16 bulls were evaluated on a switchback feeding trial fed to two pens. Triticale silage and alfalfa silage were fed separately as treatments. Average weight gain was 0.7 kg/day for the triticale silage treatment and 0.8 kg/day for the alfalfa silage treatment. Year three evaluated 25 bulls fed primarily triticale silage. The average weight gain was 0.9 kg/day. Year four evaluated 23 bulls fed triticale silage resulting in an average weight gain of 0.6 kg/day. The CAFFBT provided a venue to evaluate these bulls and highlight the potential for weight gain on forage diets and assist with selection of genetically superior bulls.
