In the period from 14 to 21 d, the level of inclusion of canola meal showed a statistically significant effect (P < 0.05) on daily feed consumption. The quadratic
response increased to a maximum corresponding to the inclusion of 22.9% of canola meal and decreased thereafter. The response to daily weight gain, feed conversion,
and average bird weight was not significant, as shown in Table 2. The presence of sinapine and others antinutritional factors, including glucosinolates in canola meal may have caused a reduction in feed consumption (Mushtaq et al., 2007; Min et al., 2011). In addition, an increase in the level of inclusion of canola meal results in an increase in the level of fiber in the diet. In turn, this increase decreases the protein digestibility and the consumption of feed by the birds, producing decreased weight gain, as noted in the present study at 7 to 14 d of age
