This investigating was performed to examine the effect of different dietary fat source (canola oil and
poultry fat) on broiler performance. 252 day-old broilers chicks (Ross 308) were randomly distributed in seven
groups include 12 in each with 3 replicates and were fed with experimental diets for 3 weeks (21-42 d-old). The
diets were as follow: 1) basal diet (control), basal diet with 3 or 6% canola oil, basal diet with 3 or 6% poultry
fat, basal diet with mixed 1.5% canola oil +1.5% poultry fat and basal diet with mixed 3% canola oil +3%
poultry fat. Feed intake, feed conversion ratio, daily weight gain and carcass characterizes were evaluated
during rearing period. Significant different were observed for feed intake (p<0.05). Adding 3 % canola oil and
poultry fat resulted in significant improvement in body weight (p<0.05) and better feed conversion ratio in fed
groups 3 % canola oil and poultry fat than other groups observed (p<0.01). No significant different were found
in liver, breast, thigh weights in between groups fed lipid in comparison with the control group. Addition of
6% poultry fat caused significant increasing on abdominal fat (p<0.05). Gizzard weight was significantly higher
in control group in comparison with supplemented groups (p<0.05). These findings suggest that adding 3%
canola oil or 3% poultry fat to the broiler diet based on corn and soybean meal can improve broiler performance
and carcass quality in fed 6% canola oil than other groups was better, may be because of adequate mixture of
fatty acids in supplemented canola oil.
Key words: Canola oil, poultry fat, performance and broiler, broiler, , ,
