Overzicht van ontwikkelingen in het voedergebruik met name dat van granen, olien en andere krachtvoeders, grasland, voedergewassen en andere ruwvoeders. Speciale aandacht wordt besteed aan de ontwikkelingslanden, waarbij een poging is gewaagd de oorzaken van genoemde ontwikkelingen te verklaren vanuit prijs- en politiek gezichtspunt. Tevens worden belangrijke ontbrekende gegevens onderkend binnen de voedsel- en veehouderijsektoren van zich ontwikkelende landen

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.

Recent Advances in Animal Nutrition — 1982 focuses on the compositions of animal feeds. The book first discusses the presence of molds and mycotoxins in animal feeds. Controlling mycotoxin exposure, formation and effects of mycotoxins, and microbiology of feeds are described. The text surveys the anti-nutritive factors in animal feeds. Substances depressing digestion or metabolic utilization of proteins; substances reducing the solubility or interfering with the utilization of mineral elements; and substances inactivating or increasing the requirements of vitamins are discussed. The book also highlights oilseed meals for livestock feeding; the use of databases for the composition and nutritive value of animal feeds; and energy evaluation of poultry rations. The text underscores the influence of nutrition on hatchability, including the composition and size of hatching eggs; the right amounts of proteins, lipids, vitamins, and minerals; feed ingredients; and feeding practices. The book also discusses the energy and protein requirements of pigs and methods used in the analysis of the energy content of ruminant feeds. The selection is a good source of data for readers interested in studying the compositions of animal feeds.
