Download or read book Swine Feeding and Nutrition written by Tony Cunha and published by Elsevier. This book was released on 2012-12-02 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swine Feeding and Nutrition provides detailed information on aspects of swine production. It begins with a presentation of the past, present, and future of swine industry. Then, it reviews the many factors that can affect nutrient requirements and needs. This text summarizes minerals, vitamins, proteins, amino acids, carbohydrates, fiber, fatty acids, fat, energy, water, enzymes, and antibiotics and other antimicrobial compounds in swine industry. Furthermore, it discusses the relative value of feeds for use in swine diets and the feeding requirement for baby pig, growing-finishing pigs, and the breeding herd. This book will be very valuable to beginners in swine production, established swine raisers, feed manufacturers and dealers, county agents, farm advisors and consultants, and veterinarians. Animal science and agriculture students and instructors will also find this book helpful.
Download or read book Swine Nutrition written by Elwyn R. Miller and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Should we aim for genetic improvement in host resistance or tolerance to infectious disease written by Andrea B. Doeschl-Wilson and published by Frontiers E-books. This book was released on with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in quantitative genetic and genomic studies have shed light on the important role of genetic control strategies for reducing disease risk and severity in livestock populations. There are two alternative host defence strategies to infectious pathogens that could be enhanced by genetic selection: improvement of host resistance versus improvement of host tolerance to infectious pathogens. Resistance refers to mechanisms that restrict the reproduction rate of a pathogen within a host, whilst tolerance mechanisms focus on minimising the damage that a pathogen inflicts on the host. Both strategies may have a similar impact on individual host fitness and performance, but can have contrasting effects on population performance and disease risk and severity. For example, improving host resistance may result in successful eradication of a disease from a livestock population, whereas disease eradication may be difficult if hosts are tolerant as these can harbour the pathogen without showing obvious or severe symptoms. On the other hand, it has been argued that increasing host resistance would fuel the arms race between host and pathogen and stimulate pathogen evolution towards higher virulence. Increasing tolerance, in contrast, imposes no or little selection pressure on the pathogen. Further, whereas disease resistance mechanisms may be specific to a particular pathogen (e.g. development of specific antibodies), tolerance mechanisms that repair damaged tissues are associated with the host rather than the pathogen, and are thus more likely to be generic to a range of pathogens. Hence, improving tolerance may be beneficial if individuals are exposed to a variety of pathogens or pathogen strains, and disease eradication has proven difficult. In contrast to evolutionary biology and plant breeding, animal breeding has only recently started to seriously consider a distinction between disease resistance and tolerance and their consequences. However, a deeper understanding of the underlying mechanisms and implications of improving either or both of the host defence mechanisms on future disease risk and severity is urgently needed by animal scientists, veterinarians and breeders to make informed decisions that help to maintain healthy livestock populations and guarantee food security. The topic ‘genetic improvement of disease resistance v tolerance’ would lend itself to research papers covering a variety of aspects that need to be considered, such as ‘how to obtain genetic parameter estimates and genomic breeding values related to disease resistance / tolerance’, ‘evidence for host genetic influence of resistance or tolerance’, ‘genetic, genomic and immunological understanding of resistance / tolerance mechanisms’, ‘epidemiological consequences of improving disease resistance / tolerance’. I believe that this research topic is both timely and relevant, and that sufficient knowledge is available across disciplines for composing valuable research / review articles that stimulate interest to a wide range of readers of Frontiers, and thus promote the growth of this journal.
