Abstract:
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.
