Horse Feeding and Nutrition is the fourth in a series of books on animal feeding and nutrition that focuses on horse feeding and nutrition, aiming to assist in world food production. Organized into 20 chapters, the book contains basic information on horse industry, feeding problems, and importance in food production of proper horse nutrition. The introductory chapters discuss the importance of the horse industry; the art, science, and myths in feeding horses; the problems involved in supplying an adequate level of nutrients in horse rations; and the digestion of feeds. Chapters 5-10 cover concise, up-to-date summaries on macro- and micronutrients, including vitamins, minerals, protein, and water. The book goes on, examining the important interrelationships between nutrition, disease, and performance; the relative value of various feeds in horse rations; and the value of pasture and hay for horses. Chapters 15-18 focus on feeding the foal, growing horses; the performance and race horses; and the mares and stallions. The final chapters discuss purified rations for horses, antibiotics, founder, learning ability, feeding behavior, nutrient toxicity, weight equivalents, weight-unit conversion factors, and the effect of cold weather on horses. The book provides information helpful to beginners and experts in horse production. It will also be valuable for county agents, farm advisors, consultants, veterinarians, and teachers of vocational agriculture, as well as animal science students and teachers.
