The text discusses the principles of animal nutrition and feed technology, including the estimation of common macro elements such as calcium and phosphorus, as well as the cell wall fractionation and detection of toxic principles in feeds. Part II focuses on the feeding of ruminant animals, including cattle, buffalo, sheep, and goats, in different physiological stages and the formulation of their respective rations. Part III covers the feeding of non-ruminant animals, such as swine and poultry, and the formulation of their diets in different physiological stages. The book is also useful for postgraduate students, animal science teachers and researchers, feed industry personnel, field veterinarians, animal husbandry workers, and animal farmers.
