Recent Advances in Animal Nutrition-1978 is a collection of papers that tackles various topics concerning livestock feeding. The book presents a total of 12 materials that cover different livestock, particularly poultry, pigs, and dairy cows. The text first covers poultry feeding related topics, such as the factors affecting amino acid requirements of meat birds; protein-energy interactions in broiler and turkey rations; and nutrition-disease interactions of leg weakness in poultry. Next, the book tackles pig feeding concerns, including amino acid nutrition of the pig; energy requirements of the growing pig; and processing and preparation of cereals for pig diets. The remaining chapters discuss topics relevant to dairy cow diet, such as ratios for high-yielding dairy cows; concentrate feeding of dairy cows; and complete-diet feeding of dairy cows. The text will be most useful to both researchers and practitioners of animal related disciplines, such as agriculture and veterinary medicine.
