Swine Feeding and Nutrition provides detailed information on aspects of swine production. It begins with a presentation of the past, present, and future of swine industry. Then, it reviews the many factors that can affect nutrient requirements and needs.

This text summarizes minerals, vitamins, proteins, amino acids, carbohydrates, fiber, fatty acids, fat, energy, water, enzymes, and antibiotics and other antimicrobial compounds in swine industry. Furthermore, it discusses the relative value of feeds for use in swine diets and the feeding requirement for baby pig, growing-finishing pigs, and the breeding herd.

This book will be very valuable to beginners in swine production, established swine raisers, feed manufacturers and dealers, county agents, farm advisors and consultants, and veterinarians. Animal science and agriculture students and instructors will also find this book helpful.
