Broilers fed with phytase addition improved average body mass, daily gain and feed conversion. Supplementing phytase decreased content of Ca, P, Mn, Zn, Cu and Fe in intestine and also decreased quantity of excreted Ca and P in the environment, i.e. increased digestibility P (p is less than 0.01) and Ca (p is less than 0.05) in feed. Use of supplemental phytase decreases the excretion of phosphorus and protects the environment contamination.
