Nutritional Impacts the Health and Physiology of the Avian Gastro-intestinal Tract


Book Description

The physiology of birds is regulated by the interplay internally between the gastrointestinal functioning, endocrine, nervous and defensive systems (immune and anti-oxidative). Acting on these are external factors such as nutrition and the gastrointestinal microbiome. One focus of this Research Topic is the importance of various nutritional physiological approaches, the parameters to be employed and an assessment of their reliability and feasibility. Aims of this topic include the following: 1) Identify specific interventions to facilitate the elimination of food borne pathogens in poultry 2) Develop nutritional strategies to reduce food borne colonization in poultry and reduce prevalence of food borne pathogens in poultry products Increasing numbers of poultry are raised without antibiotics. There is growing attention to using dietary supplements to replace antibiotics, to alter intestinal microbial populations, to stimulate antioxidative and immune systems and to improve overall intestinal health. This Research Topic will include a focus on determining the viability of nutritional intervention like probiotics and non-antibiotic growth promoters, alone or in combination, as a means to mitigate food borne contamination, particularly in the context of an antibiotic-free setting. Particular attention will be paid in determining the effects of dietary supplements on intestinal integrity, gene expression, antioxidative systems and pro-inflammatory cytokines. Reviews and research papers, among other article types, on all aspects of the interactions between nutrition, physiology and microbiology in birds, particularly poultry.




Avian Gut Function in Health and Disease


Book Description

This book contains conference proceedings of the 28th Poultry Science Symposium of the World's Poultry Science Association held in Bristol, UK, in September 2005. It focuses on the discontinued use of antibiotics in poultry and on the interactions between the birds, dietary factors and pathogens. The 23 chapters include the history, current use and legislative aspects of feed additives in the European Union; poultry nutrition without antibiotics; early development of the small intestinal function; absorptive function of the small intestine; epithelial structure and function of the hen intestine; immunological development of the gut; molecular approaches to the analysis of the gastrointestinal microbial ecosystems; microbial flora of the chicken digestive tract; mechanisms of pathogen control in the digestive tract; effect of nonstarch polysaccharidases on gastrointestinal function; effects of amino acid and protein supply on nutrition and health; the role of feed processing on gastrointestinal function and health in poultry; the causes, prevention and the role of nutrition in the production of wet litter; influence of gut health and immunity on micronutrient supply; virus-induced gastrointestinal diseases of chickens and turkeys; the digestive tract as an entry point for bacterial infections; Eimeria spp. genetics, protection and antigen identification; developments and constraints of feed acidification in controlling gut pathogens in poultry, with an emphasis on Salmonella spp., competitive exclusion in poultry production; Campylobacter spp. and their bacteriophages in poultry; breeding for disease resistance; The EU perspective on the monitoring of zoonoses and zoonotic agents and the significance of gastrointestinal problems to poultry farmers. This book will be of interest to researchers in food science and veterinary medicine, decision makers and poultry farmers.




Nutrition and health of the gastrointestinal tract


Book Description

Microbial agents (particularly bacteria) represent the greatest risk to public health. The traditional end-product oriented food inspection systems are inadequate for identifying and eliminating the usually symptomless animal carriers of agents causing foodborne infections and intoxications. Modern, risk-based, prevention approaches are the only effective way to reduce the prevalence of these hazards from our foods. As an additional 'safety-valve' microbial decontamination procedures are currently being suggested and its implementation in industrial food processing has, at least in some parts of the world, met with governmental approval. The residues in foods of some non-microbial agents have more recently also caused substantial consumer disquiet. This equally applies to non-conventional foods containing GMO's. In this publication these issues are addressed by invited expert scientists from various disciplines, many of which have key-positions in EU-funded research programmes on these very topics and/or are advisers to international public health bodies. The editors firmly believe that the very nature of the theme, the excellence of the papers and the holistic approach chosen will draw an audience from both an industry and academic background.




Formula for the future: nutrition or pathology?


Book Description

Animal production is constantly changing. Over recent years, feed costs have increased significantly. Furthermore, today more emphasis is being placed on the health and welfare of production animals and birds, and in particular to the risk of zoonoses and potential food scares. The pig and poultry industries must now address not only the costs and efficiency of production, but also the impact of health and disease to both animals and the consumer. This edited collection of papers is taken from a series of seminars that brought together some of the world's leading authorities in the field of pig and poultry nutrition, health and production. The fundamental theme is to address the issues of nutrition and health, and in particular to cover the interactions and potential conflicts between the two. The importance of digestive function and the influence of nutrition on health and disease are covered in-depth. Strategies to combat salmonella and mycotoxins are also discussed. 'Formula for the future: nutrition or pathology' is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences.

Derived from the 28th Poultry Science Symposium of the World's Poultry Science Association (UK), this book focuses on the current interest of the phasing out of antibiotic use in poultry and covers in-depth interactions between the bird, its diet and potential pathogens. It also demonstrates. the understanding of the gut health in the 21st century of commercial poultry and flocks and the ultimate safety of poultry product in the human food chain.




Gut Health: The New Paradigm in Food Animal Production


Book Description

Gut health and specifically the gut microbiome-host interaction is currently a major research topic across the life sciences. In the case of animal sciences research into animal production and health, the gut has been a continuous area of interest. Production parameters such as growth and feed efficiency are entirely dependent on optimum gut health. In addition, the gut is a major immune organ and one of the first lines of defense in animal disease. Recent changes in animal production management and feed regulations, both regulatory and consumer driven, have placed added emphasis on finding ways to optimize gut health in novel and effective ways. In this volume we bring together original research and review articles covering three major categories of gut health and animal production: the gut microbiome, mucosal immunology, and feed-based interventions. Included within these categories is a broad range of scientific expertise and experimental approaches that span food animal production. Our goal in bringing together the articles on this research topic is to survey the current knowledge on gut health in animal production. The following 15 articles include knowledge and perspectives from researchers from multiple countries and research perspectives, all with the central goal of improving animal health and production.
