Download or read book Intensive Beef Production written by T. R. Preston and published by Elsevier. This book was released on 2013-10-22 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensive Beef Production, Second Edition focuses on the technologies, methodologies, and approaches involved in beef production, including genetics, breeding, feed utilization, fertility, and growth efficiency. The publication first elaborates on the beef market, carcass composition and quality, and genetic improvement. Discussions focus on breeding systems, correlation between traits, selection for meat production in dairy cattle, body weight and composition, carcass evaluation, consumption, and international trade. The book then examines genotype, physiology of digestion and feed utilization, and beef calf production, including factors controlling feed intake, nitrogen utilization, artificial methods of augmenting fertility, birth weight, calf mortality, and weaning weight. The text takes a look at dairy calf production, breed, sex, and hormones, and growth and efficiency. Topics include energy concentration and source, grain processing, protein, antibiotics, vitamins, growth mechanisms, breed, hormones, breed suitability, and mortality and disease. The book is a valuable reference for researchers interested in beef production.
Download or read book Safety of Genetically Engineered Foods written by National Research Council and published by National Academies Press. This book was released on 2004-07-08 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.

Download or read book Beef Cattle Production and Trade written by Lewis Kahn and published by CSIRO PUBLISHING. This book was released on 2014-04-15 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beef Cattle Production and Trade covers all aspects of the beef industry from paddock to plate. It is an international text with an emphasis on Australian beef production, written by experts in the field. The book begins with an overview of the historical evolution of world beef consumption and introductory chapters on carcass and meat quality, market preparation and world beef production. North America, Brazil, China, South-East Asia and Japan are discussed in separate chapters, followed by Australian beef production, including feed lotting and live export. The remaining chapters summarise R&D, emphasising the Australian experience, and look at different production systems and aspects of animal husbandry such as health, reproduction, grazing, feeding and finishing, genetics and breeding, production efficiency, environmental management and business management. The final chapter examines various case studies in northern and southern Australia, covering feed demand and supply, supplements, pasture management, heifer and weaner management, and management of internal and external parasites.

Download or read book The Genetics of Cattle 2nd Edition written by Dorian Garrick and published by CABI. This book was released on 2014-11-28 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the time of domestication more than 10,000 years ago, cattle have played an increasingly crucial role in the development of human civilizations. Progress has been quite remarkable since the turn of the century; the sequencing of the bovine genome in 2009 launched new avenues for furthering our understanding of theoretical and practical aspects of cattle genetics. Covering a vast array of questions, this book reviews major topics from molecular and developmental genetics, disease resistance and immunogenetics to genetic improvement of dairy and beef breeds, addressing all current problems in the field. This second edition includes a new team of authors and completely new chapters on the genetics of fat production, nutrition, feed intake and efficiency, growth and body composition. Fully updated throughout, it provides a valuable resource on cattle genetics for researchers, breeders, veterinarians and postgraduate students.
Download or read book Genetics and the Behavior of Domestic Animals written by Temple Grandin and published by Academic Press. This book was released on 2013-04-22 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavior is shaped by both genetics and experience--nature and nurture. This book synthesizes research from behavioral genetics and animal and veterinary science, bridging the gap between these fields. The objective is to show that principles of behavioral genetics have practical applications to agricultural and companion animals. The continuing domestication of animals is a complex process whose myriad impacts on animal behavior are commonly under-appreciated. Genetic factors play a significant role in both species-specific behaviors and behavioral differences exhibited by individuals in the same species. Leading authorities explore the impact of increased intensities of selection on domestic animal behavior. Rodents, cattle, pigs, sheep, horses, herding and guard dogs, and poultry are all included in these discussions of genetics and behavior, making this book useful to veterinarians, livestock producers, laboratory animal researchers and technicians, animal trainers and breeders, and any researcher interested in animal behavior. - Includes four new chapters on dog and fox behavior, pig behavior, the effects of domestication and horse behavior - Synthesizes research from behavioral genetics, animal science, and veterinary literature - Broaches fields of behavior genetics and behavioral research - Includes practical applications of principles discovered by behavioral genetics researchers - Covers many species ranging from pigs, dogs, foxes, rodents, cattle, horses, and cats

This book was released on 2008-10-17 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.
