"Continued genetic development of pigs and poultry has been the foundation of profitable production within a competitive market. However, the challenges of these production increases have undoubtedly taken their toll on reproductive function in all breeding livestock, with the incidence of infertility increasing at an alarming rate. For example, it has recently been estimated that over 40% of sows are culled due to fertility problems, compared to just 12% with feet and leg issues. This edited collection of papers is taken from a series of seminars, devoted to bringing together some of the world’s leading authorities in the field of pig and poultry reproduction. The fundamental aim being to re-examine the current trends in productivity in the pig and poultry industries, and to identify nutritional means to improve fertility. It considers the effects of essential nutrients in optimising productivity, and discusses innovative applications of nutrition that will help to enhance fertility. The success of such innovations within entrepreneurial integrated systems is also covered, together with the importance of producing a quality chick and piglet at birth/hatching. Finally, the role of management and the need for least cost production is discussed. Nutritional Approaches to Arresting the decline in Fertility of Pigs and Poultry is aimed at nutritionists and animal producers as well as students and researchers studying animal and applied biological sciences."
This book contains the proceedings of the 40th University of Nottingham Feed Conference. Authors of all chapters are international experts in their fields and have provided comprehensive analyses of the issues together with practical applications. This book is essential reading for all involved in animal production science/practice, including researchers, consultants, animal science students, legislators and practitioners.
Swine Nutrition is a comprehensive text-reference that deals with the various aspects and knowledge in swine nutrition. The book is basically about nutrient utilization by swine. The topics discussed concerning this subject are factors influencing swine nutrition, nutrient bioavailability, appetite and feeding behavior, physical forms of feed, environment and management, immunocompetence, genetic and sex considerations, mycotoxins, and intestinal microbiology. Major and unique feedstuffs, feeding regimen in different stages of growth, and techniques in swine nutrition research are also elaborated. The text will be useful to students of advance swine nutrition courses as well as those seeking information in swine nutrition.

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.
The collection of papers in this book and its companion volume, Property Rights in Social and Ecological Context: Case Studies and Design Applications, (*) examine the relationships between people, the environment, and property rights and the ways in which a given social and ecological context affects those relationships. The papers are products of a research program at the Royal Swedish Academy of Sciences, Stockholm. The main objective of the program was to convene social scientists and natural scientists to address research questions in their full social and ecological dimensions. The program's participants addressed five general issues related to property rights and the environment: (1) the design of governance systems for sustainability; (2) the relationship between equity, stewardship, and environmental resilience; (3) the use of traditional knowledge in resource management, (4) the mechanisms that link people to their environments, and (5) the role played by population and poverty. The companion volume presents case studies that address questions of design application in those five areas. (*) Also available: Property Rights in a Social and Ecological Context: Case Studies and Design Applications. (ISBN 0-8213-3416-6) Stock No. 13416.
This book examines how biotechnology can improve livestock breeding and farming, and thereby also animal products. In the first chapters the reader will discover which techniques and approaches are currently used to improve animal breeding, animal health and the value of animal products. Particular attention is given to reproduction techniques, animal nutrition and livestock vaccines that not only enhance animal health but also have a significant effect on human health by ensuring safe food procurement and preventing zoonotic diseases. In addition, modern biotechnology can increase not only productivity but also the consistency and quality of animal food, fiber and medical products. In the second part of the book, issues such as how animal biotechnology could affect the environment and the important topic of animal waste management are explored. In the concluding chapter, the authors discuss future challenges related to animal biotechnology. This work will appeal to a wide readership, from scientists and professionals working in animal production, to those in farm animal management and veterinary science.
This book is an up to date reference work covering all aspects of macro and trace element nutrition in farm livestock. Sufficient information is given on metabolism, functions and interactions to explain why needs, feeds and imbalances are not always easy to define or anticipate. The major emphasis is on the mineral nutrition of ruminant livestock since they are most likely to be affected by imbalances but where pigs and poultry are the more vulnerable, extensive coverage of the non-ruminant is given. This new edition of a highly successful text has been thoroughly revised and significantly expanded. Many chapters have been extensively updated and several chapters on new topics introduced. * Calcium, phosphorus, sodium and potassium are now treated separately * Over 40 new figures are presented, and extensive use made oftables to summarise important data * Chapters on trace elements have been drastically revised * Claims for enhanced availability for new chelated sources arecritically reviewed * Completely new chapters focus on: The unique need of the ruminant for elemental sulphur Occasionally beneficial elements and essentially toxic elements The improved conduct and interpretation of supplementation trials
The Laboratory Rat, Volume I: Biology and Diseases focuses on the use of rats in specific areas of research, ranging from dental research to toxicology. The first part of this book retraces the biomedical history of early events and personalities involved in the establishment of rats as a leading laboratory animal. The taxonomy, genetics and inbred strains of rats are also elaborated. The next chapters illustrate the hematology, clinical biochemistry, and anatomical and physiological features of the laboratory rat. This text concludes with a description of infectious diseases that may be contracted from laboratory and/or wild rats. This volume is a good source for commercial and institutional organizations involved in producing rats for research use, specialists in laboratory animal, animal care and research technicians, as well as students in graduate and professional curricula.
