Recent Advances in Animal Nutrition: 1991 is an annual review of the changes and updates in the field of animal nutrition, especially progresses in the study of feeds. The book is divided into five parts. Part I discusses topics related to pig nutrition and feeds such as energy-protein interactions and improved utilization of amino acids. Part II covers the nutrition and growth of poultry. Part III talks about the legislations concerned with feed manufacture, and Part IV deals with nutrition of different animals such as chicks and ruminants. The text is recommended for agriculturists, zoologists, and those involved in the development and manufacture of feeds who would like to know more about the nutrition of agriculturally important animals.
