This book brings together the data of latest international research and was conceived as the result of a summer school held at the Inra Centre of Clermont-Ferrand/theix from 24 September to 4 October 1990. The subject is the rumen as a fermentor and the means by which rumen fonctioning can be optimized for the maximum benefit of the ruminant. Most space has been given to the reports written by international specialists in rumen microbiology, physiologists, nutritionists and animal production workers. Several of the points raised in the book are the subject of current scientific debate. These topics were dealt with in workshops and round-table discussions and are presented at the end of the book in the form of short reports.
