A survey of the literature showed that forage processing, that is grinding and pelleting, increased feed intake of ruminants. This increase, due to reduction in particle size distribution of the forage, depends mainly on forage quality, proportion of concentrates in the diet and nutrient requirement of the cow. Pellets could replace part of the concentrates; complete substitution for long forage caused digestive disorders and reduced fat content of the milk. Eating rate, microbial breakdown and production of volatile fatty acids often increased too. Processed forages offered to sheep and beef cattle depressed digestibility, which was compensated by slightly lower losses of methane and less heat production.

Studies in the Agricultural and Food Sciences: Energy Metabolism is a compilation of works on the energy metabolism in animals, especially animals of agricultural importance. The book is written by authoritative workers in the field and is divided into six parts; each chapter is based on a selected paper presented at the Eighth Symposium on Energy Metabolism held at Cambridge in September 1979. The text discusses feed evaluation; use of energy for maintenance and growth; and simulation models for energy exchange and growth. The book also covers the comparative aspects of energy metabolism; use of energy in production and lactation; and metabolic responses in the growing animal. The monograph is recommended for those who plan to study about energy metabolism of farm animals and its relationship with certain biological processes. The book will also appeal to those who develop feeds and methods that can help improve energy metabolism of farm animals.

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.

Feed Energy Sources for Livestock focuses on the compositions of animal feeds. The book first looks at the background of world grain supplies from 1972 to 1974 and 1975 onwards. The text discusses alternatives to conventional cereals. Fats in ruminants, pigs, and poultry diets; chemically treated straw; and less conventional raw materials are described. The book also looks at molasses and its by-products, processing of cereals, and the effects of an alkali technique on the nutritive value of straws. The text discusses as well the laboratory methods used in evaluating the energy value of feedstuffs. Neutral detergent fiber; in vitro rumen digestibility; Tilley and Terry in vitro rumen method; in vitro true digestibility; and modified acid detergent fiber are considered. The book then focuses on the sources, availability, and use of additional phosphorous for ruminants; selenium and Vitamin E in poultry rations; and the use of rapeseed meal in pig and poultry rations. The selection is a valuable source of information for readers wanting to study the contents of animal feeds.

Provides a historical foundation as well as a review of the state-of- the-art in forage science, detailing 25 years of progress in forage quality, evaluation, and utilization, along with the latest developments and new directions for future research. The volume is divided into six sections: overview of forage science; identification and quantitative measurement of forage quality components; intake as a critical element of forest quality; role of digestion and metabolism in determining forage quality; integrating concepts affecting changes in forage quality; and improving forage quality and evaluation.
