Three hundred,
1-day-old Wenchang broiler chickens
were brooded together for 2 weeks, then randomly
allocated into four treatments with five
replicates of 15 birds each. Birds were fed a
corn-soybean basal diet supplemented with
TRE at 0, 100, 200 and 300 mg/kg for 12 weeks.
The results revealed that a TRE-supplemented
diet had no significant effect (P>0.05) on the
body weight, although birds fed a diet with TRE
at 100 and 200 mg/kg had higher average daily
weight gains and average daily feed as compared
to controls from 9 to 12 week (P
