Download or read book Specific Nutrients for Posthatch Poultry and Postweaning Pigs written by Ganfeng Yi and published by . This book was released on 2003 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of six experiments were conducted to evaluate the effects of supplementing specific nutrients including menhaden fish meal (MFM), spray-dried plasma (SDP), glutamine (GLN), glutamate (GLU), monosodium glutamate (MSG), nucleotides (NUC), and a hatchling supplement (Oasis) in the diets of posthatch poultry and postweaning pigs on the growth performance, small intestinal morphology and immune responses. In the first experiment (Chapter II), during the first week, feeding 3% SDP improved growth performance of posthatch broilers. However, at d 3, 7 and 14 posthatch, no effects on villus height (VH) and villus height:crypt depth (VCR) ratio of broilers were observed by feeding GLN, MFM and SDP supplemented diets. In the second experiment (Chapter III), from d 0 to 7 after hatch, feeding 3 to 12% MFM resulted in linear increase in weight gain and feed efficiency of turkey poults. Feeding 1% GLN improved feed efficiency of turkey poults from d 0 to 21 posthatch. The third experiment (Chapter IV) indicated feeding the 1% GLN for 48 hours was more effective than 1% MSG, 0.8% NUC, or 1% GLU in restoring the disrupted intestinal morphology of 48 hours fasted broiler chicks. In the fourth experiment (Chapter V), from d 0 to 7 postweaning, feeding the 3.5% SDP and the GLU + NUC mixture diets improved the daily gain of pigs, and feeding the 3.5% SDP, GLU + NUC mixture and NUC diets increased the VH of jejunum of weaned pigs. In the fifth experiment (Chapter VI), the results indicated that feeding 7% SDP or 2% GLN was effective in alleviating growth depression caused by an E. coli K88 + challenge. Feeding either SDP or GLN mitigated villus atrophy and intestinal morphology disruption after E. coli challenge, indicating the beneficial effects of SDP and GLN in preventing pathogenic invasion and maintaining normal intestinal integrity and function. Feeding SDP or GLN may have different modulatory mechanism on the GH/IGF-1 uncoupling under an E. coli challenged situation. The sixth experiment (Chapter VII) indicated that broiler chicks having access to feed or Oasis immediately after hatch was beneficial for growth performance and resistance to subsequent E. maxima coccidiosis challenge. Glutamine supplementation was beneficial for the growth performance and livability of birds posthatch. Fasting for 48 h immediately after hatch impaired the gut development, immune system maturation and growth performance of broilers. Vaccination with E. maxima was proven to be effective to alleviate growth performance depression and intestinal infection associated with E. maxima challenge. In summary, these specific nutrients had different beneficial roles in the growth performance, intestinal morphology and immune responses of posthatch poultry and weaned pigs. Especially, glutamine was effective in maintaining the intestinal integrity and function of broilers and pigs under fasting and immune challenged (Escherichia coli K88 + or E. maxima) situations.

Available in PDF, EPUB and Kindle. Book excerpt: Disturbances in the gastrointestinal (GI) tract caused by internal and external influences can cause large economic losses in both the pig and poultry industries. Traditionally, diseases and conditions of the GI tract that can cause losses have been controlled by antimicrobial compounds administered in the feed and (or) water, such as antibiotics, coccidiostats, zootechnical feed additives and trace elements such as zinc and copper. However, legislation and rulings in various parts of the world coupled with a growing sentiment to reduce the use of these compounds in the intensive livestock industries have caused a reassessment of measures to influence GI tract structure and function ('gut health'), and have caused unparalleled interest in alternative strategies (genetic, dietary, management, environmental) to effectively manage the GI tract under conditions of external and internal challenge. Despite the wide array of products and strategies available to the pig and poultry industries that influence 'gut health', a term in itself that is often misunderstood and misinterpreted, it is important that the industries continue to investigate and understand the underpinning sciences that influence GI tract structure and function, especially at critical life stages. Ultimately, the cost-benefit of adopting such practices to influence 'gut health' requires consideration.

This book was released on 2021-07-15 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antimicrobial resistance is a global and increasing threat. Stewardship campaigns have been established, and policies implemented, to safeguard the appropriate use of antimicrobials in humans, animals, and plants. Restrictions on their use in animal production are on the agenda worldwide. Producers are investing in measures, involving biosecurity, genetics, health care, farm management, animal welfare, and nutrition, to prevent diseases and minimize the use of antimicrobials. Functional animal nutrition to promote animal health is one of the tools available to decrease the need for antimicrobials in animal production. Nutrition affects the critical functions required for host defence and disease resistance. Animal nutrition strategies should therefore aim to support these host defence systems and reduce the risk of the presence in feed and water of potentially harmful substances, such as mycotoxins, anti-nutritional factors and pathogenic bacteria and other microbes. General dietary measures to promote gastrointestinal tract health include the selective use of a combination of feed additives and feed ingredients to stabilize the intestinal microbiota and support mucosal barrier function. This knowledge, used to establish best practices in animal nutrition, could allow the adoption of strategies to reduce the need for antimicrobials and contain antimicrobial resistance.
Download or read book Weaning the pig written by J.R. Pluske and published by BRILL. This book was released on 2023-08-28 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Weaning the Pig: Concepts and Consequences' is a new book that addresses the major issues surrounding the weaning process, both for piglets and the breeding herd, in modern-day pig production. The post-weaned pig presents many challenges to the manager, stockperson and nutritionist, and as such is a critical phase in the overall production system. Numerous challenges are also faced by the sow, which is required to be rebred as soon as possible after weaning. This book draws together summaries of research dealing with both piglets and the sow, and is a unique book in this regard. Accordingly, the material presented covers in detail the following areas associated with the weaning process: growth of the weaned pig, nutritional management in preparation for weaning, behavioural changes and adaptations around weaning, voluntary feed intake, digestive physiology, modulation of small intestinal integrity, the intestinal microflora and diarrhoeal diseases after weaning, intestinal immunity, nutritional requirements and intestinal requirements of the weaned pig, environmental and housing issues after weaning, saving and rearing supernumery and underprivileged piglets, and productivity and longevity of the weaned sow. The chapters have been written by acknowledged experts from around the world. The book is an ideal reference for all professions associated with the pig industry, and is invaluable as a text for students at both undergraduate and postgraduate levels.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.

Download or read book Food Emulsifiers and Their Applications written by Richard W Hartel and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food emulsions have existed since long before people began to process foods for distribution and consumption. Milk, for example, is a natural emulsion/colloid in which a nutritional fat is stabilized by a milk-fat-globule membrane. Early processed foods were developed when people began to explore the art of cuisine. Butter and gravies were early foods used to enhance flavors and aid in cooking. By contrast, food emulsifiers have only recently been recognized for their abil ity to stabilize foods during processing and distribution. As economies of scale emerged, pressures for higher quality and extension of shelf life prodded the de velopment of food emulsifiers and their adjunct technologies. Natural emulsifiers, such as egg and milk proteins and phospholipids, were the first to be generally utilized. Development of technologies for processing oils, such as refining, bleaching, and hydrogenation, led to the design of synthetic food emulsifiers. Formulation of food emulsions has, until recently, been practiced more as an art than a science. The complexity offood systems has been the barrier to funda mental understanding. Scientists have long studied emulsions using pure water, hydrocarbon, and surfactant, but food systems, by contrast, are typically a com plex mixture of carbohydrate, lipid, protein, salts, and acid. Other surface-active ingredients, such as proteins and phospholipids, can demonstrate either syner- XV xvi Preface gistic or deleterious functionality during processing or in the finished food.
