Sažetak

An experiment was conducted to study the effect of phytase enzyme (Natuphos 500) supplementation in Japanese quail (Coturnix japonica) (3 to 45 days of age) on body weight, carcass performance, percentage of tibia bone ash and tibia phosphorus. Data were analyzed as a completely randomized design arranged with five levels (150, 300, 600, 1200 and 2400 FTU/Kg) of phytase enzyme as treatments 1, 2, 3, 4 and 5, respectively, and two control groups (positive and negative controls). None of the phytase levels had eff ect on carcass yield at 45 days of age (p>0.05), except first treatment with 70.06% of carcass yield that was significantly different than treatment 5 (p<0.01). The treatment 5 for percentage of tibia ash was 59.83% that was significantly different compared to the other treatments (p<0.01). Treatment 3 increased (p<0.01) phosphorus of tibia ash at 45 days of age (240.22 mg). Experimental replicates were not significantly different in any stage (p>0.05). Female quails at body weight, slaughter weight, carcass weight without viscera and legs weight were better than male (p<0.01), but male quails at carcass yield (69.06%) were significantly different (p<0.01) in contrast to the females (66.30%).
