This experiment was conducted with the aim to see the effect of phytase enzyme supplementation on feed broilers chicks comprising (250,500,750 and 1000 FTU/kg feed). For said purpose, two hundred ten (210) of one day-old commercial broiler chicks (VenCobb-500) were divided into five groups (T0, T1, T2, T3 & T4) of 42 birds in each with fifteen replicate of 14 broilers in each. The birds of (T1, T2, T3 & T4) groups were feed with basal diets having (250FTU, 500FTU, 750FTU and 1000FTU/kg) respectively, while T0 group was feed without any phytase. The experiment was conducted for 42 days and the birds of T4 group having significantly (p<0.05) higher body weight gain, feed consumption and feed conversion ratio, carcass cuts, visceral organ mass (edible and inedible parts) dressing percentage and no found any mortality than T0 (control),T1, T2and T3 groups. But no significant difference was found in carcass cut (neck, head, legs) also visceral organ mass (edible and inedible parts) (gizzard, crop, spleen,) of broiler chickens of various groups. Thus, the results show that the phytase enzyme having better effect on growth performance than control. A forementioned trial was carried out in winter season.
