PREFACE Increasing demands upon agricultural production ne- cessitate continued greater efficiency of animal produc- tion. Changes in breeding and management, and the introduction of new feedstuffs and methods of feed pro- cessing influence nutrient metabolism and requirements; hence, there is a continuing need for reevaluation. Be- cause of the variety of factors that influence require- ments, the quantitation of nutrient requirements is a complex area. This report reflects the increased knowl- edge and improved methodology in the establishment of nutrient requirements for swine during various stages of the life cycle. This Eighth Revised Edition of Nutrient Requirements of Swine has been prepared by the Subcommittee on Swine Nutrition, Committee on Animal Nutrition, Board on Agriculture and Renewable Resources, Commission on Natural Resources of the National Research Council. Changes from the previous edition and some considera- tion in applying the information contained herein in- clude: 1. Modification of recommended requirements reflects new information. 2. Since the outward signs of many nutrient deficien- cies are similar, pictures of animals meant to depict signs of simple nutrient deficiency have been omitted. 3. Tables of nutrient requirements have been ex- panded to include trace elements and requirements for a live weight range of 1 to 5 kg. 4. The availability of nutrients in ingredients used in swine diets is known to vary. Many of the requirements listed are based upon the feeding of corn-soybean meal diets and should not be considered as absolute values. In formulating diets, the relative availability of nutrients must be considered, especially when the main ingredi- ents are not cor n and soybean meal. No margin of safety for such variation has been included. 5. Nutrient requirements and feed composition data are expressed on an air-dry basis (90 percent dry matter). 6. A table of common mineral sources for swine has been included. 7. All data are presented in the metric system with tables of equivalents and conversion factors shown. 8. Feed ingredients are identified by International Feed Numbers adopted by the Committee on Animal Nutrition (United States) and the National Committee on Animal Nutrition (Canada). 9. For more detailed information on nutrients and re- search related to requirements, pertinent literature cita- tions are listed in the Bibliography. Grateful appreciation is expressed to members of the Committee on Animal Nutrition (United States), the Na- tional Committee on Animal Nutrition (Canada), and others who provided information and suggestions. The subcommittee is also indebted to Philip Ross, Executive Secretary, and Selma P. Baron, Staff Associate, of the Board on Agriculture and Renewable Resources, for their assistance in the production of this report, and to A. I. Aydin, Joseph H. Conrad, Tony J. Cunha, George K. Davis and Ernest R. Peo, Jr., for their comprehensive reviews and constructive comments on the report. Subcommittee on Swine Nutrition HOWARD S.
