The plasma amino acid concentrations of cafeteria-fed and standard-fed rats gavaged either an essential amino acid mixture or saline solution have been studied from 14 to 30 days after birth. The consumption of a cafeteria diet caused higher levels in many amino acids. The amino acid-gavaged cafeteria-fed rats showed the highest cysteine levels. The amino acid gavage produced lower concentrations of alanine, glutamate+glutamine, hydroxyproline, proline and ornithine, in both cafeteria-fed and standard-fed animals. The results show that the supply of amino acids has a positive effect on nitrogen retention and amino acid availability in cafeteria-fed pups.
对出生后14至30天经口灌喂必需氨基酸混合物或盐溶液的自由选择饮食喂养和标准饮食喂养大鼠的血浆氨基酸浓度进行了研究。自由选择饮食导致许多氨基酸水平升高。经口灌喂氨基酸的自由选择饮食喂养大鼠的半胱氨酸水平最高。在自由选择饮食喂养和标准饮食喂养的动物中，经口灌喂氨基酸均使丙氨酸、谷氨酸+谷氨酰胺、羟脯氨酸、脯氨酸和鸟氨酸的浓度降低。结果表明，氨基酸供应对自由选择饮食喂养幼崽的氮保留和氨基酸可利用性有积极影响。
