Nutrition is a very broad discipline, encompassing biochemistry, physiology, endocrinology, immunology, microbiology and pathology. Presenting the major principles of nutrition of both domestic and wild animals, this book takes a comparative approach, recognizing that there are considerable differences in nutrient digestion, metabolism and requirements among various mammalian and avian species. Explaining species differences in food selection, food-seeking and digestive strategies and their significance to nutritional needs, chapters cover a broad range of topics including digestive physiology, metabolic disorders and specific nutrients such as carbohydrates proteins and lipids, with particular attention being paid to nutritional and metabolic idiosyncrasies.
