and J. Bums discuss mechanisms of altering cell wall utilization. The book contains a 16 page index. Forage Cell Wall Structure and Digestibility is a superb book which is indeed a “bench-mark reference publication”. The book is very readable, although a list of abbreviations at the front would have been very helpful since the book will be read by people with diverse backgrounds. Figures of high quality are included. The length of the text is indicative of the depth of discussion by the various authors and the chapters are well referenced. In several instances it was obvious that discussion at the symposium influenced the final text and improved the balance of the book. Synopsis chapters in general worked well, with authors integrating and interpreting previous sections in light of their own conceptualization of the subject. I was particularly interested in views on fruitful areas for new research presented by many of the authors. This book is a “must” for researchers and educators working in the area of forage quality. Moreover, although there is a lot of very technical material, a wide range in topics is presented and the book will have a wider appeal than its title might suggest. For example, information in the chapter on environmental and genetic effects on cell wall composition and digestibility can be readily applied by animal nutritionists and agronomists as weil as by forage and livestock producers. This book provides excellent value for your money and has my highest recommendation. G. W. MATHISON

Antinutritional factors in legume seeds Recent Advances of Research in Antinutritional Factors in Legume Seeds. A.F.B. van der Poel, J. Huisman and H.S. Saini (Editors). Proc. Second Int. Workshop on Antinutritional Factors ( ANFs) in Legume Seeds, EAAP Publication No. 70, Wageningen Pers, Wageningen, Netherlands, 1993, 550 pp., NLG 275, hardcover, ISBN 90-74 134-08-4. This book is a compilation of papers presented at the Second International Workshop on Antinutritional Factors in Legume Seeds held in Wageningen, The Netherlands, December, 1993. The First International Workshop on the same subject was held in Wageningen in 1988. The objective of the Second Workshop was to review findings since the first workshop on antinutritional factors ( ANFs) in grain legumes, with an emphasis on analytical methods, mode of action of ANFs, and means of reducing ANFs in legume seeds. The book is divided into three major sessions, with a main paper for each session followed by research

reports. The sessions are Analytical Methods, Mode of Action and Negative Effects in Animal Species, and Reduction of ANFs. The main paper in each session presents a state-of-the-art literature review. A unique aspect of the main papers is that they are coauthored by at least two authors, from at least two different countries. The objective of the shared authorship was to widen the geographic and scientific scope of the presentations. The particular ANFs covered include trypsin inhibitors, lectins, tannins, alkaloids, and antigenic proteins. Main papers are presented in each major subcategory in each session (e.g. Session I, Analytical Methods, main papers on Proteinaceous ANFs, Tannins, Alkaloids ) . There were a total of 11 main papers, and 62 short papers. This volume was published in time to be available at the symposium, so the proceedings are certainly current. The book is attractive in design and printing. The short papers represent a broad spectrum of current research on ANFs. In the Analytical Methods section, new results and techniques for analysis of protease inhibitors and tannins are emphasized, for application to soybeans, field beans, fava beans, lupins and peas. In the Mode of Action and Negative Effects in Animal Species section, greatest emphasis is placed on trypsin inhibitors, lectins, tannins and antigenic proteins. New information on the nutritional effects of trypsin inhibitors, including their resistance to degradation in the rumen, is presented. In the last section, Reduction of ANFs, plant breeding and feed processing are emphasized. Numerous papers on various methods of heat treatment for inactivation of ANFs are included. Biotechnological techniques for ANF reduction, emphasizing microbial enzymes, are presented. The most successful enzymatic treatments involve those which degrade phytate and non-starch polysacchar-ides in legume seeds such as soybeans.This book will be useful to specialists in the study of natural toxins, and animal nutritionists involved in research with grain legumes. ANFs in peas are particularly well covered in this volume. The main papers are useful, interpretative reviews of current knowledge of legume ANFs. The short papers are variable in quality, but by and large are useful contributions. The book will be of most value to research specialists, and less so to practical nutritionists in the feed industry. P.R.
