Applied Veterinary Clinical Nutrition
Well-referenced clinical resource for canine and feline nutrition, with expansions throughout and two new chapters covering birds and small mammals.
Fully revised to reflect new advances and information throughout, the Second Edition of Applied Veterinary Clinical Nutrition presents current, authoritative information on all aspects of small companion animal nutrition. The book provides clinically oriented solutions for integrating nutrition into clinical practice, with introductory chapters covering the foundation and science behind the recommendations and extensive references for further reading in every chapter.
With contributions from more than 25 leading veterinary nutritionists, Applied Veterinary Clinical Nutrition covers topics such as:
* Integration of nutrition into clinical practice, basic nutrition, energy requirements, and pet food regulations in North America and Europe that also apply to many other regions
* Using and reviewing pet food labels and product guides, feeding the healthy dog and cat, and abridged clinical nutrition topics for companion avian species & small mammals
* Commercial and home-prepared diets, and nutritional management of body weight and orthopedic, skin, and gastrointestinal diseases
* Nutritional management of exocrine, hepatobiliary, kidney, lower urinary tract, endocrine, cardiovascular, and oncological diseases as well as enteral and parenteral nutrition
A valuable resource on the principles of small animal nutrition and feeding practices in health or disease, Applied Veterinary Clinical Nutrition is a widely trusted and practical daily reference for veterinary practitioners including specialists, residents, and students seeking expert information on feeding their canine, feline, avian, and small mammalian patients.
