Factors Affecting Calf Crop summarizes the latest information available from leading cattle physiologists and geneticists regarding factors known to influence the production of live calves at weaning. You get practical information on management techniques for improving reproduction efficiency in the herd. You'll also learn about the functioning of the reproductive system and how this may affect reproductive processes in the cow herd. Managers will benefit from a clearer understanding of the factors known to limit efficient reproduction, while veterinarians and other professionals who advise cattlemen will appreciate the substantial reference material and color photographs for defining cow condition scores. Color photographs are also used to illustrate the discussions of testicular thermographies and their applications. Other chapters in the book cover developments in improving reproductive performance of the replacement heifer, the brood cow, and the bull. Topics on reproduction include physiology/endocrinology, the use of growth promotants, genetics and physiological and economic considerations in selecting the age to breed heifers, heritability of fertility, length of the breeding season, prepartum and postpartum nutrition, nursing by the calf, cloning of embryos, and much more.

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
