This work was conducted to investigate the effects of phytase on the growth performance, excreta excretion, and N and P excretion of broilers for 7 weeks. One hundred ninety two Ross broiler (one-day-old) with average weight 44.7±1.5 g were assigned randomly to 4 treatments groups (12 birds/pen, 4 pens/treatment) as 2×2 complex factors of sex of broiler (♂, ♀) and phytase 2 treatments (0, 300 FTU/kg), and fed experimental diets for 6 weeks (starter, 0~2 wk; earlier, 2~4 wk; finisher, 4~7 wk). The experimental diets included that phytase was added to the basal diet. Body weight was high at male treatment and at phytase treatment. Feed intake was high at male treatment and was no difference between phytase and non-phytase treatment. Feed efficiency was the highest at male and phytase treatment. Manure excretion was high at male treatment and reduced at phytase treatment. Excretion of N and P was high at male treatment and at non-phytase treatment. Finally, when phyase was added to basal diet, the growth performance of broilers was improved and excreta excretion and N and P excretion of broilers were decreased.
