The regulation of histidine and arginine intake in rats was investigated using the self-selection feeding method. The usefulness of the self-selection feeding technique for the determination of amino acid requirements is also discussed. When weanling rats were offered a choice of two diets differing only in histidine or arginine content for 2 weeks, they chose diets to support maximal growth, with the exception of some groups that did not grow to the maximum level. Histidine and arginine intake of the self-selecting rats ranged from 0.25% to 2.22% and from 0.43% to 2.43% of the diets ingested. These results demonstrate clearly that rats have the ability to consume a minimum amount that satisfies histidine and arginine needs for maximal growth. Previous and the present results suggest that the self-selection feeding method is a useful technique for the determination of amino acid requirements in growing rats.
采用自选喂养法研究了大鼠对组氨酸和精氨酸摄入量的调节。还讨论了自选喂养技术在确定氨基酸需求量方面的实用性。当给断奶大鼠提供两种仅组氨酸或精氨酸含量不同的日粮供其选择两周时,它们选择了能支持最大生长的日粮,但有一些组未生长到最大水平。自选大鼠的组氨酸和精氨酸摄入量分别占摄入日粮的0.25%至2.22%和0.43%至2.43%。这些结果清楚地表明,大鼠有能力摄入满足最大生长所需组氨酸和精氨酸的最低量。之前和目前的结果表明,自选喂养法是确定生长大鼠氨基酸需求量的一种有用技术。
