Consequently, a diet based on corn and cDDGS provides good levels of substrate for xylanase,
and it is therefore of interest to study its potential benefits in such diets (Beg et al., 2001). However, there are few reports
on the relationship between dietary cDDGS and xylanase supplementation on the growth performance of broilers. In the
present study, there were significant interactions between cDDGS and xylanase on BWG in both growth periods and FI in
the second period. These results indicated that the effect of xylanase may be dependent on the levels of dietary cDDGS, and
this needs further study
