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
Seed Quality: Basic Mechanisms and Agricultural Implications focuses on various aspects of seed quality and integrates research at basic and applied levels, supporting high-quality seeds as the basis of higher agricultural productivity. With its clear perspective and interdisciplinary focus on basic and applied aspects of seed quality, this book is immensely useful to students and teachers in many agricultural and botanical disciplines. Because seed quality is a critical component in the economic considerations of the farmer and the seedman alike, Basra looks in-depth at these aspects of seed production: seed viability seed health seed vigor seed testing variety identification crop yield seed storage seed production seed deterioration seed treatments Seed quality is of international agronomic concern, and the recent upsurge of interest in seed quality has accentuated a new awareness regarding its importance in crop production. This book meets the need for information and could form the basis of long-range planning by policymakers on quality assurance and management programs and in the facilitation of international trade. Researchers, students, and teachers in many agricultural and botanical disciplines--seed science and technology in particular--will find this book to be of immense use. It can be used as a handbook for those involved in seed industry and seed testing services. It is recommended for international courses in seed science and technology and seed training programs.
