Book Description
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.

Book Description
Fall calving cows were used to determine the effects of protein supplementation on reproduction, and growth and carcass characteristics of calves. Cows were individually supplemented from mid-November to mid-March for four years with either a control diet (Con; 1.82 kg/d of 38 % CP) or low diet (L; 0.2 kg/d of 8% CP). During each year, cows were reassigned dietary treatments according to calving date and BCS, with half of Con and L cows remaining on the same diets as the previous year and the other half assigned to the other diet. Cows were exposed to bulls for 60 d beginning December 1. Statistical analyses were performed with a 2 x 2 factorial design with PROC GLM and PROC FREQ. Cows on Con diets lost less BW from November to January compared with L cows (-29.8 ± 2.8 and -49.7 ± 2.8 kg, P
