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.

Download or read book Mineral Tolerance of Animals written by National Research Council and published by National Academies Press. This book was released on 2006-01-22 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess minerals in the diet and water of animals can have an adverse effect on animal health, consumers, and the environment. Preventing unsafe mineral exposure is a fundamental part of animal nutrition and management. At the request of the Food and Drug Administration, the National Academies convened a committee to make recommendations on animal tolerances and toxic dietary levels, updating a 1980 report on mineral tolerance in domestic animals. Based on a review of current scientific data and information, the report sets a "maximum tolerable level" (MTL) for each mineral as it applies to the diets of farm animals, poultry, and fish. The report includes an analysis of the effects of toxic levels in animal diets, and it identifies elements that pose potential human health concerns. The report recommends research that includes a better characterization of animal exposure to minerals through feedstuffs; a better understanding of the relationship between mineral concentrations in feed and water and the levels in consumer products such as meat, milk, and eggs; and more research on the maximum tolerable level of minerals for aquatic and companion animals.

Download or read book Zinc Signals in Cellular Functions and Disorders written by Toshiyuki Fukada and published by Springer. This book was released on 2014-09-25 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the crucial role of "zinc signals" in biological processes on a molecular and physiological basis, discussing future directions and questions underlying this unique phenomenon. To accomplish this, a group of worldwide leaders in the field, who have made outstanding contributions, overview zinc signals from a professional standpoint. Zinc plays an indispensable role in various cellular processes. It regulates a great number of protein functions including transcription factors, enzymes, adapters, and growth factors as a structural or catalytic factor or both. Recently, another function of zinc has received extensive interest and attention because of its potential importance as a signaling mediator. Zinc plays a dynamic role as an intracellular and extracellular signaling factor and thus regulates cellular signaling pathways, which enables communication between cells, conversion of extracellular stimuli to intracellular signals, and control of various intracellular events. These functions of zinc have become recognized as “zinc signals,” which play critical roles in physiology, and therefore their imbalance can cause a variety of problems with regard to human health. Because the notion of zinc signals is quite new and no integrative review books focusing on them have yet been published, we believe this book will provide very timely information on the subject and thus should be of importance and interest to a wide range of readers.

Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Download or read book Nutritional Strategies of Animal Feed Additives written by Abdel-Fattah Z. M. Salem and published by NOVA. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quality of feed nutrition is influenced not only by the content but also by some other aspects such as, feed presentation, hygiene, anti-nutritional factors, digestibility and palatability. Feed additives provide a mechanism by which such dietary deficiencies can be addressed and also benefits not only associated with the nutrition and thus the growth rate of the animal concerned, but also its health and welfare. Feed additives could modify animal metabolism in specific and direct ways by improving production efficiency (weight gain or milk yield); improving carcass composition in growing animals; increasing milk yield in lactating animals; and decreasing animal waste per production unit. This book discusses the impacts of feed additives on animal metabolism, health and production.

Download or read book Rational Livestock Nutrition in Rural Areas written by Maja Słupczyńska and published by Tudás Alapítvány. This book was released on 2020-01-15 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Livestock nutrition is one of the most important issue in animal production both in physiological-economic terms as well as the impact of livestock on the environment. The handbook „Rational livestock nutrition in rural areas” has been funded with support from the European Commission under Erasmus + programme – Cooperation for innovation and good practice. The book has been developed by experts in various fields of agriculture – animal nutrition and feed science, animal husbandry, agronomy and veterinary medicine. The authors of this book, originating from five different countries – Poland, Turkey, Romania, Italy and Hungary by working within the framework of the established Strategic Partnership – Vocational Education and Training have developed a comprehensive compendium aimed at transfer of knowledge, good practice and innovation in the field of agriculture with emphasis on rational nutrition of livestock. The book covers five broad issues of livestock nutrition. Chapter one – „Physiology of Nutrition”, is related to the anatomy and functions of particular organs of the farm animals’ digestive tracts, type of nutrients found in the livestock diets, as well digestion, absorption and metabolism of these compounds. An extensive characteristics of most common used in animal nutrition feeds, their processing, feed additives as well as the mechanism of their action are presented in the second chapter – „Feed and Feed Additives”. The chapter number three – „Animal Feeding Systems in Europe” in a synthetic way explains the fundamentals of commonly used feeding systems of ruminants, pigs, poultry, horses and rabbits. This chapter also provides several schemes of daily rations/concentrate mixtures formulation for various farm animal species. An extensive chapter number four is dedicated to animal welfare as well etiology, treatment and prevention of metabolic diseases in animals that livestock breeders are struggling every day. Last but not least, the fifth chapter raises issues related to livestock production in terms of environmental and legal conditions under the common agricultural policy of member countries. The possibilities of reducing the negative impact of livestock production on the environment, so called „good practices” are discussed in this chapter. The book “Rational Livestock Nutrition in Rural Areas” is intended for people involved in animal production – mainly farmers but it can also be used by agricultural and nutritional consultants, zootechnical service workers. Students of vocational agricultural schools and, to some extent, students of natural and agricultural universities may benefit this book as well.

Download or read book Nutrient Requirements of Beef Cattle written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-06-16 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

Download or read book Hazards associated with animal feed written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-11-04 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for feed for terrestrial and aquatic animals continues to rise with the increasing demand for foods of animal origin; however, the challenge is not only to meet the growing need for feed but also to ensure its safety and thus contributing to the safety of the entire food chain. Feed safety incorporates the impact on human as well as animal health and welfare, which, in turn, can affect productivity. Hazards in feed may be inherent to feed ingredients as well as introduced during feed production, processing, handling, storage, transportation, and use. Hazards in feed may also result from accidental or deliberate human intervention. The expert meeting reviewed and discussed potential hazards in feed of chemical, biological and physical origin. It addressed hazards, as well as their occurrence in feed are described, and transfer from feed to food, relevance for food safety, impact on animal health, and emerging issues and trends. In addition, specific consideration was given to feed and products of feed production technologies of increasing relevance, for instance insects, former food and food processing by-products, biofuels (bioethanol and biodiesel) by-products, aquatic plants and marine resources.
