Abstract
Two groups of chicks were fed, until they were 3 weeks old, diets supplemented with either DL-methionine (MET) or DL-2-hydroxy-4-methylthiobutanoic acid (HMB). Oxidation to CO2 and uric catabolism of intraperitoneally injected L-[1-14C]MET and DL-[1-14C]HMB were studied comparatively for 8 h. HMB supplementation spares available MET from both oxidative and uric catabolism.
摘要
两组雏鸡在3周龄前分别喂食添加了DL-蛋氨酸（MET）或DL-2-羟基-4-甲硫基丁酸（HMB）的日粮。对腹腔注射的L-[1-14C]蛋氨酸和DL-[1-14C]HMB氧化生成二氧化碳及尿酸分解代谢进行了8小时的比较研究。添加HMB可减少氧化代谢和尿酸分解代谢中可用蛋氨酸的消耗。
