Influence of Fats in Rations on Storage Quality of Poultry

Abstract

IN RECENT years, fats have become a surplus commodity. Research, directed toward finding new uses for fats, has shown that fat is a desirable ingredient in livestock and poultry rations and as a result, increasing amounts of fats are being used in feeds.Through the use of high energy fats, lower cost rations which give satisfactory growth response and which have better physical characteristics have been developed. It was reported by Scott et al. (1947) that high energy poultry feeds outperform low energy rations. Siedler and Schweigert (1953) observed that the growth response in New Hampshire chicks on 2, 4 or 8 percent fat (choice white grease) with or without supplements of choline or choline plus antibiotics and vitamin B12 did not increase rate of gain over that of chicks on the basal ration for a period of 9 weeks. An increase in rate of gain was noted, however, in …
