Feedstuff Evaluation contains the proceedings of the 50th University of Nottingham Easter School in Agricultural Sciences, held at Sutton Bonington in July 1989. The book presents papers discussing a wide range of topics on the accurate evaluation of feedstuffs for livestock. Initially, systems of expressing the nutritive value of feeds are considered. Modifications to feeding value as influenced by animal factors including intake and palatability are discussed. Specific dietary ingredients, being plant polysaccharides, fats, minerals and vitamins are detailed. Prediction of the nutritive value of compound feeds and individual feeds through classical wet chemistry and the more recent NIR is assuming considerable importance in the rapid evaluation of diets. Associated with these developments is an appreciation of the relevance of both inter- and intra-laboratory variation in determinations. Finally, the need to collate information into an interactive data-base is being actively pursued. It is evident that safety of animal feeds is becoming an increasingly topical issue and the last session considered the relevance of naturally-occurring toxic factors, residues, mycotoxins and, finally, animal pathogens. Veterinarians, farmers, farm administrators, and those involved in every aspect of nutrient supply to animals will find the compendium very insightful and informative.
