Introduction

This volume of studies from the World Animal Review contains articles published on ruminant nutrition in the first twenty-four issues of the journal, presenting the experience and the results of work of animal scientists from 11 countries. Although the principal focus of the articles is on the feeding of ruminant animals in the developing areas of the world, several basic studies and information from the developed countries are included as well.

The text of this volume has been organized into five parts. The first part comes after a general article on the international collection and dissemination of information on animal feeds: it deals with pastures, forages and their utilization. The second part is concerned with the role of poor-quality roughages and by-product feeds in animal feeding and is followed by the third part on unconventional feeds. Protein and mineral utilization constitutes the fourth part. The largest number of articles is in the fifth and final part which is devoted to feeding systems and strategies for ruminant production.

This volume highlights the need for a continuing re-assessment of feed resources for the livestock sector. Not only are new feeds required which do not compete with man's own food needs, but traditionally available feeds should be better utilized to increase animal productivity. These call, inter alia, for wide-ranging fundamental and applied research studies to provide a sound basis on which to develop animal feeding systems.
