Ruminant animals have evolved a set of stomachs harboring microorganisms which are capable of digesting fibrous materials, such as cellulose in plants. They account for almost all of the milk and more than half of the meat consumed worldwide. Therefore a great deal of research has been conducted on the digestive system of ruminants, and on the metabolism of products of digestion. As qualitative knowledge increased, it became possible to develop quantitative approaches, initially using complex statistical analyses but more recently by constructing mechanistic mathematical models. This book brings together quantitative approaches used in the study of mechanisms of ruminant digestion and metabolism. Written by leading authorities from the UK, United States, Canada and Australia, it is aimed at research workers and advanced students in animal sciences.

This book brings together the papers presented orally or as posters at the Sixth International Workshopon Modelling Nutrient Utilization in Farm Animals, held in Wageningen, The Netherlands, 6 - 8 September2004. The purpose of this book is to present current research in modelling nutrient digestion andutilization in cattle, sheep, pigs, poultry and fish.The book is organised into six sections that cover a range of topics and modelling approaches; theseare (i) absorption and passage; (ii) growth and development; (iii) mineral metabolism; (iv) methodology;(v) environmental impact; and (vi) animal production and feed evaluation. Deterministic, stochastic,empirical and mechanistic modelling approaches are described.This book will be of significant interest to researchers and students of animal science, particularly thoseconcerned with nutrition modelling.

Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.

The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes.

Mathematical modelling is increasingly applicable to the practical sciences. Here, mathematical approaches are applied to the study of mechanisms of digestion and metabolism in primary animal species. It also explores common themes between species, and provides an integrated approach to mathematical modelling in animal nutrition.
