Recent Advances in Animal Nutrition-1984 documents the proceedings of the Eighteenth Annual Nutrition Conference for Feed Manufacturers. It covers a wide range of topics pertaining to the nutrition of farm livestock. The volume is organized into four parts. Part I on poultry nutrition contains papers relating to carcass quality in broilers. These deal with the influence of diet and genotype, and various aspects of meat quality. Part II on pig nutrition includes studies on the nutrition of early weaned pigs; differences in the recommendations of the Agricultural Research Council (UK) and the National Research Council (US) for energy and protein for growing pigs; and the importance of ileal digestibility of proteins in pig feeds. Part III on ruminant and horse nutrition includes papers on the efficacy of a wide range of substances for the manipulation of rumen fermentation to increase the efficiency of production; and new chemical methods for predicting the nutritive value of forages. Part IV on dairy cow nutrition addresses the practical aspects of feeding protein to dairy cattle and manipulation of milk composition by dietary means.
