The Feeding Value of Meat and Bone Meal Protein

Abstract

KRAYBILL and Wilder (1947) investigated the feeding value of meat scrap protein and found that some samples of meat scrap were deficient in methionine and tryptophan. Meat scrap in general was a good source of lysine. March, Biely and Young (1950) also studied the supplementation of meat scrap with amino acids. They found that lysine was the principal amino acid deficiency in a practical-type ration which contained meat scrap protein. Patrick (1953) studied supplements for a meat scrap-type chick ration containing 67.5% corn and found lysine to be the principal amino acid deficiency. The severity of the deficiency depended upon the batch of meat scrap which was used. A comparison of the amino acid content of meat scrap, as reviewed by Almquist (1957), with the amino acid requirement of chicks indicated that methionine and tryptophan are probably the amino acids which limit growth. Since amino acid analyses do not necessarily …
