First published in 1989, this volume presents a detailed series of scientific reviews concerned with most of the key areas of dog and cat nutrition; for example, the volume surveys and provides data on protein and energy requirements, calcium metabolism and essential fatty acids. It shows the substantial developments in knowledge that have occurred in the subject and discusses potential trends. The volume is an expanded, updated and edited version of papers originally presented at the Seventh Waltham Symposium on advances in dog and cat nutrition, held at Queens' College Cambridge in 1985. This is a comprehensively reference volume in a subject which is scientifically challenging and of immense practical importance. The volume will provide an essential source of reference and information for practitioners and students of veterinary medicine and for nutritionists and food research scientists in academia and industry.
