This study evaluated the effects of different
levels of canola meal in broiler diets on growth
performance, nutrient digestibility, and duodenal morphometry.
A total of 320 one-day-old Cobb broilers
were used in a 35-d experiment. A completely randomized
design with 5 levels of canola meal (0, 10, 20, 30,
and 40%) as a substitute for soybean meal was used
with 8 replicates of 8 birds each. The basal diets were
formulated based on corn and soybean meal to meet
nutrient requirements of broiler chickens. The levels of
canola meal were evaluated with a polynomial regression
at 5% of significance. Weight gain and average
BW showed a quadratic response (P = 0.03 and P =
0.04, respectively), decreasing with the addition of 40%
canola meal. The apparent nutrient digestibility of DM
