Abstract/Summary Enzyme products did not have a significant effect (P>0.05) on weekly fed intake and weight gain of birds. But feed intake tended to drop and weight gain tended to increase in response to supplementation of the three enzymes. Weight gain of the birds was increased by 0.6% with lipase, 3.7% with phytase and 2.4% with xylanase. Xylanase had a marked effect (P<0.01) on both FCR and AME, decreasing FCR from 1.52 to 1.4 and increasing AME from 12.29 to 12.60 MJ/kg. There was also a highly significant (P<0.01) interaction between the three enzymes on AME. The lipase and phytase both improved FCR but had no effect on AME. It can be concluded that AME of broiler diets containing a high level (30%) of rice bran may be improved by xylanase supplementation.
