The Sulfur Amino Acid Requirement of the Chick from 4 to 8 Weeks of Age as Affected by Temperature

Abstract

ALMQUIST (1952) reviewed the literature concerning the methionine requirement of the young chick and concluded that the requirement was approximately 0.45 percent of the diet and that the total sulfur amino acid requirement was approximately 0.8 percent of the diet. Briggs et al. (1942), Grau and Kamei (1950), and Jukes and Stokstad (1951) suggested that the sulfur amino acid requirement was nearer 0.9 percent of the diet, whereas, McGinnis and Evans (1947), Milligan et al. (1951) and West et al. (1951) reported sulfur amino acid requirements of 0.71, 0.72 and 0.74 percent, respectively. Nelson et al. (1960) stated that the quantitative requirement for sulfur amino acids was approximately 3.51 percent of the protein.Baldini and Rosenberg (1955) found that the methionine requirement, expressed as a percentage of the diet, increased as the energy level of the diet increased. Rosenberg and Baldini (1957) further stated, as did Almquist (1952) further stated, …
