A study was made of protein utilization in rats given a variety of low-protein diets containing (g/kg) egg albumin 18, casein 49, gluten 50, or mixtures of either maize protein and gelatine 58, or casein and gelatin 37, each with supplemental methionine. The diets were limiting in leucine, tryptophan or lysine, or in both tryptophan and the sulphur-containing amino acids. 2. Values obtained for net protein utilization (NPU) at these low levels of nitrogen intake were markedly higher than the amino acid score calculated for the different test proteins, except with casein for which the two values were similar. The NPU values agreed more closely with chemical score values based on the content of S-amino acids or isoleucine in the dietary protein.

对给予各种低蛋白饮食的大鼠的蛋白质利用情况进行了研究，这些低蛋白饮食含有（克/千克）：卵清蛋白18、酪蛋白49、面筋50，或玉米蛋白与明胶的混合物58，或酪蛋白与明胶的混合物37，每种都添加了蛋氨酸。这些饮食在亮氨酸、色氨酸或赖氨酸方面，或在色氨酸和含硫氨基酸两者方面是受限的。2. 在这些低氮摄入量水平下获得的净蛋白质利用率（NPU）值明显高于针对不同测试蛋白质计算的氨基酸评分，除了酪蛋白，其这两个值相似。NPU值与基于膳食蛋白质中S - 氨基酸或异亮氨酸含量的化学评分值更为接近。
