The quantitative requirement for the amino acids lysine, tryptophan, and methionine was determined for the hatchling green sea turtle (Chelonia mydas). Hatchling green sea turtles were fed synthetic diets of purified substances with the composition of the diet varying in the amount of lysine, tryptophan or methionine present. The lysine requirement was found to be 4.8% of the crude protein (N X 6.25) or 1.7% of the dry diet. The tryptophan requirement was found to be 0.63% of the crude protein or 0.22% of the dry diet. The methionine requirement, in the presence of adequate cystine (3.1% of the crude protein), was found to be 1.5% of the crude protein or 0.49% of the dry diet.
已确定孵化期绿海龟（蠵龟）对氨基酸赖氨酸、色氨酸和蛋氨酸的需求量。给孵化期绿海龟喂食由纯净物质组成的合成饲料，饲料中赖氨酸、色氨酸或蛋氨酸的含量各不相同。结果发现，赖氨酸的需求量为粗蛋白（氮×6.25）的4.8%或干饲料的1.7%。色氨酸的需求量为粗蛋白的0.63%或干饲料的0.22%。在胱氨酸含量充足（粗蛋白的3.1%）的情况下，蛋氨酸的需求量为粗蛋白的1.5%或干饲料的0.49%。
