NOTICE: The project that is the subject of this report was approved by the Governing Board of the Na- tional Research Council, whose members are drawn from the councils of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The members of the committee re- sponsible for the report were chosen for their special competences and with regard for appropriate balance. This report has been reviewed by a group other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The National Research Council was established by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and of advising the federal government. The Council operates in accordance with general policies determined by the Academy under the authority of its congressional charter of 1863, which establishes the Academic as a private, nonprofit, self-governing membership corporation. The Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in the conduct of their services to the government, the public, and the scientific and engineering communities. It is administered jointly by both Academies and the Institute of Medicine. The National Academy of Engineering and the Institute of Medicine were established in 1964 and 1970, respectively, under the charter of the National Academy of Sciences. This study was supported by Agricultural Research, Science and Education Administration of the U.S. Department of Agriculture; by the Bureau of Veterinary Medicine, Food and Drug Administration of the U.S. Department of Health and Human Services; and by Agriculture Canada.

PREFACE This report is the third revision of the joint United States- Canadian Tables of Feed Composition, NAS-NRC publication 659, issued in 1959. The first revision, publication 1232 (1964), consolidated the data in the first joint report with selected data from NAS-NRC publication 449 and NAS-NRC publication 585. The second revision was NAS-NRC publica- tion 1684 (1969~. The feeds included here were selected by the Subcommittee on Feed Composition and approved by the Committee on Animal Nutrition and its subcommittees on nutrient require- ments of domestic animals. This report brings together ana- lytical data on more than 600 feeds. Data are presented on 68 attributes (nutrients). The report provides working tables for feed manufacturers, nutritional research scientists, teachers, students, county agents, and farmers to use as adjuncts to re- ports in the NRC nutrient requirement series. This study was partly supported by financial assistance to Utah State University from the U.S. Department of Agricul- ture (USDA) and from the Agricultural Experiment Station, Utah State University. Support for subcommittee activities was received from Agricultural Research, Science and Educa- tion Administration, USDA; the Bureau of Veterinary Medicine, Food and Drug Administration, U.S. Department of Health and Hu~nan Services; and Agriculture Canada, Ottawa, Ontario. The subcommittee wishes to thank the many scientists in commercial and university laboratories who supplied data that have been used in compiling the information contained in this report. We are grateful to the Technical Committee of the USDA Cooperative Regional Project S-45 for providing data on a number of forages grown in the southeastern sec- tion of the United States. Special thanks are due L. C. Kearl, P. V. Fonnesbeck, and Howard Lloyd of the International Feedstuffs Institute, Utah State University, for their untiring efforts and special competencies in compiling and organizing the data. We are indebted to Philip Ross and Selma P. Baron of the Board on Agriculture and Renewable Resources for their assistance in the production of this report and to the members of the Committee on Animal Nutrition for their critical reviews and suggestions. We want to extend our special thanks to Donald L. Bath, Carl E. Coppock, Eugene S. Erwin, Steve Leeson, Fredric N. Owens, John V. Shutze, Milton L. Sunde, and Eric W. Swanson who reviewed the draft of the report and made helpful comments and suggestions for our consideration. The report was also reviewed by Bernard S. Schweigert for the Board on Agriculture and Renewable Resources and by Howard S. Teague for the Commission on Natural Resources. Subcommittee on Feed Composition JOSEPH H.
