BOOK REVIEWS
quirements of Trout, Salmon and Catfish. Printing and Publishing Office, National Academy of Sciences, 2101 Constitution Avenue, Washington, D.C. 20418. V + 57 pp. $3.25. As the Preface states: "Fish culture has expanded rapidly as a result of increased use of fish as human food and as feed for animals. This trend has increased the demand for information on the nutrient requirements of fish." The Contents are: Energy and Metabolism in Fish; Protein and Amino Acid Requirements; Lipid Requirements; Vitamins; Minerals; Excesses, Hypervitaminosis, and Adventitious Toxins; Symptoms of Nutritional Deficiency; Feed Processing and Storage, and Composition of Feeds. In addition there are 10 Tables, including two dealing with the composition of common fish feeds, and an Appendix which gives some typical test diets, and a Bibliography. This latest in the Nutrient Requirements series has gathered most, if not all, of the information on the requirements of the intensively reared species into one publication. Like the others in the series it is a must for nutritionists.—H.D.B. SUBCOMMITTEE ON SWINE NUTRITION, COMMITTEE ON ANIMAL NUTRITION, AGRICULTURAL BOARD, NATIONAL RESEARCH COUNCIL. Nutrient Requirements of Domestic Animals. Number 2. Nutrient Requirements of Swine. 7th revised ed. Printing and Publishing Office, National Academy of Sciences, 2101 Constitution Avenue, Washington, D.C. 20418. V + 56 pp. $2.50. The Preface points out that this edition of Nutrient Requirements of Swine differs from the
1997
previous one, published in 1968, in these respects: "Modifications of the values presented in the 1968 edition, where they occur, reflect data accumulated since that time; A short discussion of formulation of diets presents some of the problems involved in meeting nutrient requirements of swine; Since complete confinement may increase reproductive problems of the sow (problems that may or may not involve nutrient requirements), suggestions for improving reproductive performance are given." It might be well to quote part of the Introduction regarding some of the factors that should be considered in determining desirable levels of nutrients in the diet—"Stress conditions, including subclinical disease level; Variability in content and availability of nutrients in different feeds; Variability among animals in their need for nutrients; The adequacy of criteria used to determine nutrient requirements; Interrelations among nutrients; Effect of different nutrient levels on carcass quality; and Economics—the costs of different nutrient levels and their benefits." In addition to the Introduction, the main headings in the publication are: Nutrient Requirements and Symptoms of Deficiency, Antimicrobial Agents, Evaluating the Performance of Market Pigs, Experimentally Induced Symptoms of Nutritional Deficiency, Excesses of Certain Minerals, Formulating Diets, Complete Confinement, and Composition of Feeds. There are 12 tables, the first 5 of which give recommendations on nutrients, and 2 deal with the composition of some common swine feeds. A Bibliography completes the publication. It is an axiom that this publication is a must for animal nutritionists, feed manufacturers, and swine producers.—H.D.B.
Tom Newman International Award The Tom Newman International Memorial Award for 1973 has been made jointly to Dr. Alfred M. Lucas and Dr. Peter R. Stettenheim, United States Department of Agriculture, Poultry Research Branch, East Lansing, Michigan. The Award consists of a handsome medal and £50 sterling. Each winner will receive a medal and the £50 will be divided equally between them. The Award is given for what in the opinion of the Award Committee is the most important contribution to poultry husbandry research work published in the previous year, for the benefit of poultry husbandry. The Award was made to Doctors Lucas and Stet-
tenheim for their production, based on their own research and investigation with the co-operation of others, of a two-part publication "Avian Anatomy— Integument," which it was considered would be a standard work of reference for some years to come. This book was reviewed in Poultry Science 53: 447448, 1974. The Award was presented, along with other British Poultry Breeders and Hatcheries Association Awards, at a ceremony in the House of Commons, London. Dr. Lucas is a Fellow of the Poultry Science Association.
