This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Molting is a natural occurrence in the Avian species that can include a period of fasting. Animal rights groups view the long-accepted standard industry practice as inhumane. Based on influences from these groups and the recommendation of its scientific committee, United Egg Producers (UEP) requires members of its Animal Care Certified Program use a non-feed withdrawal molting program, even though the morphological and physiological effects of this method have not been studied in depth and the existing literature provides contradictory results. Research regarding how to induce a non-feed withdrawal molt has been performed using feed that is nutrient deficient or contains an additive to cease egg production. Studies have shown subsequent egg production to be comparable to hens molted using feed withdrawal. This study was designed to determine the morphological and physiological changes that occur in a non-feed withdrawal molt. Two hundred hens divided into 40 groups of 3 birds each were molted in a staggered pattern so that the morphological and physiological effects of non-feed withdrawal molt could be measured with identical environmental and housing variables. Data was divided into 5 sections including Control (n=5), Start (n=7), Mid-Molt (n-7), Near End (n=7), and Over (n=15). Internal organs were examined and measured. Corticosterone levels were measured to determine if non-feed withdrawal molting causes less stress to hens. Pertinent blood parameters including cholesterol, glucose, O2, CO2, hemoglobin, and hematocrit were also measured. Results indicate internal organ weight changes due to non-feed withdrawal molt were as expected. Decreases in the oviduct length, ovary weight, follicle weight, and follicle number indicate regression of the reproductive tract. No differences (P

Download or read book Dynamics in animal nutrition written by Jannes Doppenberg and published by BRILL. This book was released on 2023-09-04 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal nutrition is a fast changing field of expertise. Newly developed scientific knowledge is quickly adapted to better understand the integral balance between different organs and the digestive system. Society demands that the feed industry responds to consumer issues such as food safety, sustainability of animal production, animal health and welfare, carbon foot printing etc. via altering feeding programs. The practising nutritionist needs to implement this vast knowledge into practical feed formulations in a cost effective way in order to produce feeds and animal products efficiently. This book addresses current topics of interest to researchers and nutritionists in animal research, the feed and allied industry. This includes: immunomodulation, gut barrier functions in gut health, oxidative stress in weaned piglets, glutamine as an functional amino acid, energy evaluation of feedstuffs for layers, reduction of the risk of Salmonella infections, glucogenic nutrients as a predictor of milk production, reduction of methanogenesis in ruminants, glucose metabolism and insulin resistance in sows and much more. This reference book will be of vital interest to all involved in animal nutrition and the animal production industry.

Download or read book Avian Biochemistry and Molecular Biology written by Lewis Stevens and published by Cambridge University Press. This book was released on 2004-11-11 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biology of birds is diverse and frequently differs significantly from that of other vertebrates. Many birds migrate or fly at high altitudes, while egg-laying and feather production places high demands on nutrient uptake and storage. This book is the only comprehensive and up-to-date survey of avian biochemistry and molecular biology available. It emphasises the similarities and differences between birds and other vertebrates, concentrating on new developments. The first section deals with protein, lipid and carbohydrate metabolism, its hormonal control and the adaptations that occur in birds. The second covers the avian genome, gene expression, and avian immunology. Growth and embryological development are also discussed. Avian Biochemistry and Molecular Biology will be of interest to all those working on birds, especially postgraduate students and researchers.

Download or read book Commercial Chicken Meat and Egg Production written by Donald D. Bell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commercial Chicken Meat and Egg Production is the 5th edition of a highly successful book first authored by Dr. Mack O. North in 1972, updated in 1978 and 1984. The 4th edition was co-authored with Donald D. Bell in 1990. The book has achieved international success as a reference for students and commercial poultry and egg producers in every major poultry producing country in the world. The 5th edition is essential reading for students preparing to enter the poultry industry, for owners and managers of existing poultry companies and for scientists who need a major source of scientifically based material on poultry management. In earlier editions, the authors emphasized the chicken and its management. The 5th edition, with the emphasis shifted to the commercial business of managing poultry, contains over 75% new material. The contributions of 14 new authors make this new edition the most comprehensive such book available. Since extensive references are made to the international aspects of poultry management, all data are presented in both the Imperial and Metric form. Over 300 tables and 250 photos and figures support 62 chapters of text. New areas include processing of poultry and eggs with thorough discussions of food safety and further processing. The business of maintaining poultry is discussed in chapters on economics, model production firms, the use of computers, and record keeping. Updated topics include: breeders and hatchery operations; broiler and layer flock management; replacement programs and management of replacements; nutrition; and flock health. New chapters address flock behavior, ventilation, waste management, egg quality and egg breakage. Other new features include a list of more than 400 references and a Master List of the tables, figures, manufacturers of equipment and supplies, research institutions, books and periodicals, breeders, and trade associations. Commercial growers will find the tables of data of particular interest; scientists will be able to utilize the extensive references and to relate their areas of interest to the commercial industry's applications; and students will find that the division of the book into 11 distinct sections, with multiple chapters in each, will make the text especially useful.
