Interfacing Immunity Gut Health And Performance

This collection of papers is devoted to bringing together the disciplines of monogastric animal production, feed, gut physiology, microbial populations and immunity, in an understandable manner for practical nutritionists and meat producers.

This book contains an edited collection of papers, taken from a series of one day seminars, devoted to bringing together the disciplines of monogastric animal production, feed, gut physiology, microbial populations and immunity, in an understandable manner for practical nutritionists and meat producers. It provides an overview of key elements of related disciplines, some highly technical, whilst relating the science back to practical animal production. It is intended as an update on the status of specialised topics of the gut. As animal science becomes more 'multi-factorial' in its nature, understanding across disciplines will become crucial in adapting animal production practices to meet both economic and welfare demands. Contents: Future challenges in poultry meat production Early gut development: the interaction between feed, gut health and immunity Interaction of nutrition with intestinal microbial communities Commensal bacteria and intestinal development: studies using gnotobiotic pigs Regulation of gut function and immunity Controlling gastrointestinal disease to improve absorptive membrane integrity and optimize digestion efficiency Impact of mannan oligosaccharide on gut health and pig performance Index This book is ideal for nutritionists, animal producers, students and researchers studying animal and applied biological sciences.

"It is widely acknowledged that the inclusion of antimicrobial growth promoters (AGPs) in the diet of livestock increases growth rate. However, many questions arise on whether the benefits outweigh the risks, or vice versa. Recent legislative developments in the European Union and USA, recommendations by the World Health Organization, initiatives taken by the food chain, and consumer concerns all point to a widespread (voluntary) removal of antibiotic feed additives for animal growth promotion. In particular, Regulation (EC) 1831/2003 lays down provisions phasing out the authorisations of AGPs in the European Union as from 1 January 2006. This book discusses how this will affect the use/non-use practice of AGPs. Attention is given to the current status and rational design of developments and strategies for animal feeding without the inclusion of AGPs. Topics covered include benefits and risks of AGPs, risk assessment, consumer concerns and demands, regulatory aspects and international developments, mode of action and innovative alternatives, and recent advances in the analysis of AGPs and related products. This book contains peer-reviewed papers presented at the international conference ""Antimicrobial Growth Promoters: Worldwide Ban on the Horizon?"". The book is filled with valuable information on the pros and cons of use of AGPs as well as on alternative nutritional solutions. It is aimed at professionals and researchers in the feed and food industry."

This edited book is focused on SDG 14: life below water. This book covers all aspects of fish biotechnology and health management. A detailed description is provided of CRISPR Cas9 technology application in the development of superior variety of fish with better growth, disease resistance, etc., accompanied by numerous helpful photographs and schematic diagrams. In addition, recent developments in nanotechnology and its application in fisheries production enhancement have been discussed. Further, topics includes, probiotics, immunostimulants, fish genetic markers, bioremediation, metagenomics, transgenerational immune priming, application of cell culture in fisheries and nano-biosensor application on fish disease diagnosis, pollution monitoring, etc. are provided in details. . The book is helpful for researchers, teachers, students, farmers, and entrepreneurs in utilizing the knowledge on recent advancements in different aspects of fish genetics and biotechnology for future research and aquaculture production enhancement.

There has been a continual expansion in aquaculture, such that total production is fast approaching that of wild-caught fisheries. Yet the expansion is marred by continued problems of disease. New pathogens emerge, and others become associated with new conditions. Some of these pathogens become well established, and develop into major killers of aquatic species. Diagnosis and Control of Diseases of Fish and Shellfish focuses on the diagnosis and control of diseases of fish and shellfish, notably those affecting aquaculture. Divided into 12 chapters, the book discusses the range of bacterial, viral and parasitic pathogens, their trends, emerging problems, and the relative significance to aquaculture. Developments in diagnostics and disease management, including the widespread use of serological and molecular methods, are presented. Application/dose and mode of action of prebiotics, probiotics and medicinal plant products used to control disease are examined, as well as the management and hygiene precautions that can be taken to prevent/control the spread of disease. This book will be a valuable resource for researchers, students, diagnosticians, veterinarians, fish pathologists and microbiologists concerned with the management of diseases of fish and shellfish.

Fully revised and updated, this study is a significant contribution to the understanding of animal nutrition, health, and productivity. Covering an array of modern topics—from the biology of the gastrointestinal tract and the analysis of microbial populations to understanding bio-feed ingredients and the use of enzymes, oliosaccarides, probiotics, and organic acids to replace antibiotics in animal diets—this is a must-have reference for anyone involved in the animal sciences.

The practice of supplementing direct fed microbial and prebiotic additives to domestic animals during growth is becoming more widespread in food animal production. Beneficial effects particularly in cattle, pigs and poultry, including improved general health, foodborne pathogen reduction, more efficient food utilization, faster growth rate and increased milk and egg production are common results. The success associated with direct fed microbial and prebiotic applications in multiple species ensures their continued commercialization and the widespread use of such additives. However, several fundamental questions remain about how and why probiotic products work, and which kind of probiotic products are best for specific production scenarios. It appears that early establishment and retention of an ecological balance in the gastrointestinal tract is an important first step for an external biological additive to be effective in young animals. Therefore, it is possible that the effectiveness of direct fed microbials and prebiotics in some animal species may only be an indirect consequence of speeding up the establishment and succession of the dominant microflora characteristic of the adult gastrointestinal tract. Consequently, an understanding of the key processes during establishment of microflora in the gastrointestinal system that lead to the subsequent fermentation characteristics and ecological balance exhibited by the highly protective microflora is needed. Several additional areas of future research directions are also suggested for further development and implementation of these biological approaches as new molecular and drug delivery technologies become available. Continued research on direct fed microbials and prebiotics in general should markedly expand their commercial applications.
