This book was released on 1994 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: . For feeding closer to the requirements at least two diets are needed: one diet with a low nitrogen content during pregnancy and an other diet with a higher nitrogen level during lactation. The consequences of such a feeding strategy were investigated. A lower nitrogen supply during pregnancy had no effect on the development of the products of conception, but the development of the maternal protein mass was reduced during the first reproductive cycle. In the second and third parity a compensatory effect was observed. The nitrogen excretion decreased with about 35 % during pregnancy. Sow with a higher lysine supply during lactation mobilized a less nitrogen and more fat during lactation. The nitrogen excretion per sow per year can be reduced with about 25 %. However, the efficiency of the utilization of dietary nitrogen into retained nitrogen remained at a relatively low level. For an further improvement of the efficiency of the utilization of dietary nitrogen into retained nitrogen a multiphase feeding strategy in combination with a restricted development of the live weight of sows is proposed.
Download or read book Livestock production and society written by R. Geers and published by BRILL. This book was released on 2023-08-28 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to provide a scientific-based, multidisciplinary perspective to the dialogue between society and the stakeholders within livestock production. Concerns and problems related to food safety, animal welfare and rural environment are discussed within a holistic approach. This unique approach has an added-value compared to other books which cover these topics from a specialist point of view. The different issues are developed by well-known experts in their field of work. They are dealing with the latest developments in livestock production in relation to social concerns (such as, regulations, risk communication, reduction of environmental impact, sustainability and economic and social impacts of alternative strategies) and production systems (including transport and slaughter, feeding strategies, waste management and future monitoring technology).Readers from various disciplines will find these ideas useful and complimentary to their own expertise, and may apply them to decision making, vocational training and other educational applications.
Download or read book Energy Metabolism of Farm Animals written by K. J. McCracken and published by Cabi. This book was released on 1998 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Proceedings of the 14th Symposium on Energy Metabolism of Farm Animals, held in Northern Ireland in September 1997, comprises 85 original contributions by leading scientists from over 20 countries around the world. In keeping with previous Symposia in the series, held under the auspices of the European Association for Animal Production, this book contains papers which provide the latest research on the energy metabolism and other aspects of the physiology of a wide variety of farmed animals. Highlights include a comprehensive review of the current state of research on leptins and their potential applications in animal production, and a large section relating to organ and tissue metabolism, with major contributions from the USA, UK, France, Germany and Denmark. An important strength of the book is the diversity of species covered. For example, the sections on modelling and feed evaluation relate to pigs, sows, broiler chickens, laying hens, turkeys, lambs, beef and dairy cattle and fish. There are also substantial contributions on lactation and reproduction, growth, environmental aspects and maintenance. This book is essential reading for research workers in animal science, particularly those concerned with nutrition and feed evaluation.

Download or read book Nutrient Requirements of Laboratory Animals written by National Research Council and published by National Academies Press. This book was released on 1995-02-01 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparationâ€"including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.

Download or read book Feed efficiency in swine written by John F. Patience and published by Springer Science & Business Media. This book was released on 2012-10-15 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Feed efficiency in swine' has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.
Download or read book Protein Deposition in Animals written by P.J. Buttery and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein Deposition in Animals explores the factors controlling protein deposition in farm animals including fish, poultry, and ruminants. Topics covered range from protein biosynthesis in eukaryotic cells and protein metabolism in intact animals to whole-body amino acid metabolism, synthesis of egg proteins, and metabolism of the fetus. The energy costs of protein metabolism, dietary constraints on nitrogen retention, and metabolism in muscle are also discussed. Emphasis is placed on the factors that influence protein production by animals. This book is comprised of 15 chapters; the first of which explains some fundamental aspects of protein synthesis, followed by a topic of the molecular control of protein breakdown. Two chapters then consider the measurement of whole-body protein metabolism and the integration of the metabolism of individual organs with the rest of the animal. Two 'tissues', the muscle and the fetus, are singled out for detailed analysis in subsequent chapters, while another chapter describes the synthesis of egg proteins. The factors that influence overall nitrogen retention by the animals are also examined, along with the energy costs of protein deposition, hormonal influences on protein deposition, and the use of anabolic agents to manipulate growth. Two chapters, one on poultry and the other on ruminants, are concerned with predicting rates of protein deposition. This text concludes by discussing the protein metabolism in fish. This book will be of interest to scientists working in the fields of applied biochemistry, animal nutrition and physiology, physiology, and agriculture.
