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: The use of drugs in food animal production has resulted in benefits throughout the food industry; however, their use has also raised public health safety concerns. The Use of Drugs in Food Animals provides an overview of why and how drugs are used in the major food-producing animal industriesâ€"poultry, dairy, beef, swine, and aquaculture. The volume discusses the prevalence of human pathogens in foods of animal origin. It also addresses the transfer of resistance in animal microbes to human pathogens and the resulting risk of human disease. The committee offers analysis and insight into these areas: Monitoring of drug residues. The book provides a brief overview of how the FDA and USDA monitor drug residues in foods of animal origin and describes quality assurance programs initiated by the poultry, dairy, beef, and swine industries. Antibiotic resistance. The committee reports what is known about this controversial problem and its potential effect on human health.

Download or read book The Development Nutrition and Management of the Young Calf written by Carl L. Davis and published by Iowa State Press. This book was released on 1998-01-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: An indispensable resource for the dairy farmer or veterinarian, the researcher, teacher, or advanced student, this book puts the cutting–edge science of raising dairy calves into an accessible, usable form. Geared to those with a basic understanding of principles of animal nutrition and husbandry, the volume gives a comprehensive account of all aspects of calf rearing, from the rudiments of anatomy and development through the practicalities of feeding and housing. The Development, Nutrition and Management of the Young Calf begins with an overview of how the calf′s digestive system develops, highlighting the period of transition from preruminant to ruminant digestion. Here the authors provide information essential to understanding nutritional needs and restrictions during the liquid–feeding phase in the young calf as well as those factors that govern the development of a functional rumen. Major emphasis is given to the energy and protein requirements of the young calf, with attention to the effects of environmental temperature on energy requirements. The authors also review the adequacy of current National Research Council recommendations on the energy and protein requirements of young calves. They discuss the management, nutrition, and care of the pregnant cow as well as calving management necessary to deliver a healthy calf. Other topics include liquid–feeding systems, formulation and use of milk replacers and starter feeds, the weaning process, housing principles, and the interactions of nutrition and disease

Download or read book Nutrient Requirements of Beef Cattle written by Subcommittee on Beef Cattle Nutrition and published by National Academies Press. This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

This book was released on 2005-01-18 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative stress is one of the major symptoms accompanying physiological functions and numerous diseases. Oxidants and free radicals are connected with diseases such as cancer, diabetes, infectious, cardiovascular and neurodegenerative diseases and also in the aging process itself. Therefore, comprehensive knowledge of the underlying mechanisms of oxidant and free radical production and the defence against this permanent threat to cells is important for the understanding of many physiological and pathophysiological processes. This book overviews the basic mechanisms of oxidant formation and antioxidant defences. In addition, the formation of oxidants and their detoxification, the damage of macromolecules and the major repair and removal systems will be highlighted.

Available in PDF, EPUB and Kindle. Book excerpt: Michael Akers provides the basics for understanding mammary development and lactation and conveys the critical regulatory events in lactation. This text willl prove to be an invaluable overview of mamorary development and lactation for undergraduates and graduates studying lactation, new researchers, and as a review for established scientists. Additionally, the book will be an important resource for professionals in the animal and dairy industry and for those in other scientific disciplines such as food chemistry, cell biology, and endocrinology whose work is closely tied to mammary gland development and function. Lactation and the Mammary Gland covers growth and development of the mammary gland including comparisons between species. It imparts and emphasizes the critical nature of mammary growth and the onset of lactation at the time of parturition. Special emphasis is given to the endocrine and growth factor regulation of both mammogenesis and lactogenesis. A thorough discussion of the role of growth hormone in development and maintenance of lactation or galactopoiesis adds to this book's value as a text and reference. The author reviews the presence of hormones, growth factors, and other bioactive compounds in milk and mammary secretions as well as the potential for use of the mammary gland as a bioreactor in the pharmaceutical industry. A description of the nutritional and management factors in milk production round out the book's comprehensive coverage.
