AbstractThis experiment was conducted on 120 white quails during 4-6 weeks of age which were divided into 4 treatments with 3 replicates (10 birds in each replicate).The experimental treatments were T1 (control group) reared on standard ration without adding fat، while the treatments T2،T3 and T4 were feed the standard rations with adding 3% of vegetable oil، vegetable hydrolyzed fat and animal tallow respectively. Results showed that there was a significant increase (p≤0.05) in body weight، body gain in T4. While there were no significant differences in relative growth rate for all treatments except in fifth week، where the third treatment was better than second and fourth treatment but feed and protein consumption did not differ between all treatments. There were a significant improvement in feed conversion ratio and protein conversion ratio in T4 treatment comparing with other treatments. The third treatment had best economic efficiency while the fourth treatment had the best production index.
