The Proceedings of the 14th Symposium on Energy Metabolism of Farm Animals, held in Northern Ireland in September 1997 comprises 85 original contributions by leading scientists from over 20 countries around the world. In keeping with previous Symposia in the series, held under the auspices of the European Association for Animal Production, this book contains papers which provide the latest research on the energy metabolism and other aspects of the physiology of a wide variety of farmed animals. Highlights include a comprehensive review of the current state of research on leptins and their potential applications in animal production, and a large section relating to organ and tissue metabolism, with major contributions from the USA, UK, France, Germany and Denmark. An important strength of the book is the diversity of species covered. For example, the sections on modelling and feed evaluation relate to pigs, sows, broiler chickens, laying hens, turkeys, lambs, beef and dairy cattle and fish. There are also substantial contributions on lactation and reproduction, growth, environmental aspects and maintenance. This book is essential reading for research workers in animal science, particularly those concerned with nutrition and feed evaluation.
