The Effects of Fish Meal, Methionine and Different Cereal Grains in Diets of Young Turkeys

SEVERAL practical feeding experiments with growing chickens have been conducted to determine the feeding value and the unidentified growth factor content of fish meal. In experiments conducted several years ago, large increases in growth and feed efficiency of chickens resulted from the addition of fish meal to diets in the place of soybean meal on a weight or protein basis (Matterson et al., 1951; Saxena and McGinnis, 1952; Ringrose and Potter, 1952; Branion and Hill, 1953; Matterson et al., 1953). Later, in more highly vitamin-fortified rations in which fish meal was added with ground yellow corn in the place of soybean meal and stabilized fat to keep both protein and energy constant, fish meal produced only small or insignificant increases in the growth and feed efficiency of chickens (Rosenberg et al., 1955; Matterson et al., 1957). In more recent experiments in which fish meal was added to the diet in…
