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 practical research text provides an invaluable resource for all animal and veterinary scientists designing, analysing and interpreting results from nutrition and feed experiments in pigs and poultry. The emphasis throughout is on practical aspects of designing nutrition experiments. The book builds on the basics and proceeds to describe the limitations of experiment design involving different ingredients. It goes on to describe the characterization of experimental diets including ingredient selection, composition and the minimum proximate analysis required. The text details measurements and the tools available for understanding diverse data sets, data analysis and eventual publication of the research. This fully balanced and extensively referenced, yet practical, text is an invaluable resource to all animal, veterinary and biomedical scientists involved in the designing of nutrition experiments in pigs and poultry, and the publication of their research.

Each of these popular handbooks contains comprehensive information on the nutritional needs of domestic animals and includes extensive tabular data. All are paperback and 8 1/2 x 11. Some books come with diskettes or Cds that allow users to predict nutrient requirements of specific animals under various conditions and at various life stages.

Modelling is a useful tool for decision making in complex agro-industrial scenarios. Containing a selection of the papers presented at the International Symposium of Modelling in Pig and Poultry Production 2013, this book brings together the best and most recent academic work on modelling in the pig and poultry industry, with a particular emphasis on nutrition. It reviews basic modelling concepts, descriptions and applications of production models and new methods and approaches in modelling.

Nutrition of poultry-scientific progress and economic development; Intake of food and water; Digestive physiology; Energy metabolism; Metabolism of water and minerals; Physiology and nutritional role of vitamins; Feeding of growing birds; The egg and feeding of the laying hen; Feeding of breeders; Raw materials employed in poultry production; Processing of diets and nutritional consequence; Modelling of requirements and diet formulation.

Covering a variety of essential topics relating to commercial poultry nutrition and production—including feeding systems and poultry diets—this complete reference is ideal for professionals in the poultry-feed industries, veterinarians, nutritionists, and farm managers. Detailed and accessible, the guide analyzes commercial poultry production at a worldwide level and outlines the importance it holds for maintaining essential food supplies. With ingredient evaluations and diet formulations, the study's compressive models for feeding programs target a wide range of commercially prominent poultry, including laying hens, broiler chickens, turkeys, ducks, geese, and game birds, among others.
