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.
