Written for senior undergraduate and graduate students, "Animal Nutrition Science" introduces the fundamental topics of animal nutrition, in a treatment which deals with terrestrial animals in general. Addressing a wider range of topics than the standard animal nutrition texts, the subjects covered include nutritional ecology and the evolution of feeding styles, nutrients (including minerals, vitamins and water) and their functions, food composition and methods of evaluating foods, mammalian and microbial digestion and the supply of nutrients, control and prediction of food intake, quantitative nutrition and ration formulation, methods of investigating nutritional problems, nutritional genomics, nutrition and the environment, and methods of feed processing and animal responses to processed foods. The many references provide the scientific basis for the text, and give signposts for the reader to extend their enquiry in topics of interest.
