"Improving gut health in poultry is as good for the novice as it is for the experienced nutritionist...this book is a must for every poultry nutritionist."Dr Ioannis Mavromichalis, Ariston Nutrition Consulting International This collection summarises current research on the composition and function of the gastrointestinal tract in poultry, the factors that affect its function, and nutritional strategies to optimise poultry nutrition, health and environmental impact. Part 1 begins by summarising advances in sequencing and omics technologies to understand gut function. It then reviews our current understanding of the gut microbiota, the development of the gut microbiome over the life of the bird, and gut function in nutrient processing and immune response. The second part of the book reviews what we know about factors affecting gut function and health. Chapters cover gastrointestinal diseases, the interaction between pathogens and the gut as well the impact of antibiotics. The final group of chapters discuss current research on the effectiveness of feed additives in optimising gut health, including probiotics, prebiotics, synbiotics, antimicrobials, essential oils and other botanicals as well as cereal grains. With its distinguished editor and team of expert chapter authors, this will be a standard reference for poultry scientists, poultry feed manufacturers and the poultry farming community.
