The effect of administration of amino acids enriching the diet on protein utilization and rat body composition was investigated. Net protein utilization (NPU) of the diet enriched by tryptophane, lysine or sulphur-containing amino acids comprised 0.408, 0.335 and 0.664. Changes in the time of administering the amino acids allowed NPU to be attained as 0.445, 0.352 and 0.716, respectively. It has been also shown that the time of administering the amino acids produces an effect on the rat body composition. The lowest fat content was recorded in the body with tryptophane given one hour before feeding the main diet, with lysine and sulphur-containing amino acids given one and two hours after feeding the main diet.
研究了在饮食中添加氨基酸对蛋白质利用和大鼠身体组成的影响。富含色氨酸、赖氨酸或含硫氨基酸的饮食的净蛋白质利用率（NPU）分别为0.408、0.335和0.664。改变氨基酸的给药时间后，NPU分别达到0.445、0.352和0.716。还表明，氨基酸的给药时间对大鼠身体组成有影响。在喂食主要饮食前一小时给予色氨酸、在喂食主要饮食后一小时和两小时分别给予赖氨酸和含硫氨基酸的大鼠体内，脂肪含量最低。
