Available in PDF, EPUB and Kindle. Book excerpt: * Outlines the link between genes and performance in farm animals * Shows tools for more effective genetic selection * Highlights the role and ethical implications of new reproductive and molecular genetic technologies The application of scientific methods to animal breeding has led to major improvements in the output, cost and quality of animal products over the last few decades.

Download or read book Factors Affecting Calf Crop written by Michael J. Fields and published by CRC Press. This book was released on 2021-11-18 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Crossbreeding Beef Cattle written by Tony J. Cunha and published by . This book was released on 1963 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains reports presented by speakers at the Beef Cattle Short Course on Crossbreeding which was held at the University of Florida, April 12-14, 1961. The Short Course was designed to bring together the availabre information on crossbreeding of beef cattle. Accordingly, this book is a summary of what is presently known about this subject. It includes reports from Florida, Texas, Louisiana, Georgia, and other areas where considerable crossbreeding work with Brahman and British breeds is being conducted.

Download or read book Elements of Evolutionary Genetics written by Brian Charlesworth and published by Roberts. This book was released on 2010-02-03 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook shows readers how models of the genetic processes involved in evolution are made (including natural selection, migration, mutation, and genetic drift in finite populations), and how the models are used to interpret classical and molecular genetic data. The material is intended for advanced level undergraduate courses in genetics and evolutionary biology, graduate students in evolutionary biology and human genetics, and researchers in related fields who wish to learn evolutionary genetics. The topics covered include genetic variation, DNA sequence variability and its measurement, the different types of natural selection and their effects (e.g. the maintenance of variation, directional selection, and adaptation), the interactions between selection and mutation or migration, the description and analysis of variation at multiple sites in the genome, genetic drift, and the effects of spatial structure.

Download or read book Information Resources on the Care and Welfare of Beef Cattle written by Cynthia Petrie Smith and published by . This book was released on 2004 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main animal welfare concerns in beef cattle production is that of pain and distress. Dehorning, castration, and branding are husbandry procedures which can cause pain and discomfort. Less acute but still distressful are those issues related to the animal environment. Extreme natural conditions can result in cattle that are heat and/or cold stressed. Drought and the resulting overstocking for available feed resources can also reduce body fatness. These are important welfare issues in modern beef production. The following bibliography explores these issues and more and should provide a useful resource for scientists, veterinarians, extension specialists, students, and others.

Available in PDF, EPUB and Kindle. Book excerpt: Goat science covers quite a wide range and varieties of topics, from genetics and breeding, via nutrition, production systems, reproduction, milk and meat production, animal health and parasitism, etc., up to the effects of goat products on human health. In this book, several parts of them are presented within 18 different chapters. Molecular genetics and genetic improvement of goats are the new approaches of goat development. Several factors affect the passage rate of digesta in goats, but for diet properties, goats are similar to other ruminants. Iodine deficiency in goats could be dangerous. Assisted reproduction techniques have similar importance in goats like in other ruminants. Milk and meat production traits of goats are almost equally important and have significant positive impacts on human health. Many factors affect the health of goats, heat stress being of increasing importance. Production systems could modify all of the abovementioned characteristics of goats.
