The effect of feeding frequency (daily 2 times feeding for 1 hour or 6 times feeding for 30 minutes) and a different methionine content of the diet on weight gain, N-balance and metabolic 35S-methionine degradation was investigated in broiler chickens. Weight gain and N-balance were not improved by increased feeding frequency. At the high feeding frequency, weight gain and N-balance were even depressed when diets with methionine deficiency (without methionine supplementation) were fed. No effects of feeding frequency and the amount of DL-methionine supplementation on the level of excreted 35S after i.v. injection of 35S-methionine were observed.
研究了饲喂频率（每日2次，每次1小时；或6次，每次30分钟）以及日粮中不同蛋氨酸含量对肉鸡体重增加、氮平衡和代谢性35S-蛋氨酸降解的影响。增加饲喂频率并未改善体重增加和氮平衡。在高饲喂频率下，当饲喂蛋氨酸缺乏（未补充蛋氨酸）的日粮时，体重增加和氮平衡甚至受到抑制。静脉注射35S-蛋氨酸后，未观察到饲喂频率和DL-蛋氨酸补充量对35S排泄水平的影响。
