The positive control (PC) was adequate in all dietary nutrients and the negative control (NC) was deficient in phosphorus (P). The phytase HM treatments were NC supplemented with phytase HM at the indicated FYT/kg feed.

SEM: standard error of mean; ADG: average daily gain; ADFI: average daily feed intake; FCR: feed conversion ratio; Ca: calcium.
