Effect of Diet on the Ether-Extract Content of Chicken Muscles ,

IN AN investigation designed to study the influence of certain feed ingredients on the flavor of broilers, a number of diets not ordinarily encountered in investigations with chicks were used. These diets produced interesting effects on the lipid content of the muscles. Various investigators have reported the effect of diets on the fat content of domestic fowl. Generally, the diets were composed entirely of natural ingredients and the experiments were designed to yield information on the comparative fat-producing capacities of various cereals and protein concentrates. The authors are unaware of experiments of this nature in which purified diets were used. Harshaw (1936) fed heavy-breed cockerels (20–25 weeks of age) diets in which the principal sources of carbohydrate were corn, oats, and wheat middlings. No significant differences that could be ascribed to diet were found in the chemical composition of the edible portions of the cockerels. Maw (1935a) supplemented yellow …
