The non-ruminant section is concerned with environmental impact and health of pigs and poultry. The first chapter presents life cycle analysis of dietary options in broiler production. The second presents results of trials on peas and beans in pig diets. The third reviews gut health and immunity in piglets. The fourth discusses effects of diet on gut health in pigs. The fifth describes the importance of pig health on production efficiency. The final chapter reviews nutritional quality of soya products for non-ruminants.

All chapters are written by international experts and provide comprehensive analyses of issues alongside practical applications. This book is essential reading for anyone involved in the livestock industry, including nutritionists, feed suppliers, researchers, consultants, animal science students, legislators and veterinary practitioners.
