The objective of this research was to evaluate the effects of supplemental fat on beef cow and heifer performance, lactation and reproduction. Supplemental fat sources, differing in fatty acid composition, were evaluated to determine the effects on performance, lactation and reproduction in Angus x Simmental cows (Exp. 1) or heifers (Exp. 2). Feeding supplemental fat (soybeans, flaxseed, and animal fat) did not affect (P ≥ 0.05) cow BW or BCS. There were also no differences (P ≥ 0.05) among the fat sources. But, in heifers, fat supplementation increased (P

Recent Advances in Animal Nutrition-1981 is a collection of papers that discusses the effects of dietary fat on milk composition, relating it to the biochemistry of fat synthesis in the mammary gland. The influence of concentrates on milk composition as well as the pattern and level of concentrate feeding on milk output are also covered. The book describes the need for better utilization of grass and grass products in dairy production, the mineral and trace element requirements of pigs; the importance of anion-cation balance in poultry diets and its effects on performance levels; and the selenium and cobalt requirements of ruminants. The problems of medicinal residues in animal products and the toxicological effects of aflatoxin residues in animal products are also considered. People involved in agriculture, dairy production and animal nutrition will find the book useful.
