SD = Standard deviation.

T1 = experimental phytase at 250 mg TOS/kg bw/day (equivalent to 112,500 FTU/kg bw/day).

T2 = experimental phytase at 500 mg TOS/kg bw/day (equivalent to 225,000 FTU/kg bw/day).

T3 = experimental phytase at 1000 mg TOS/kg bw/day (equivalent to 450,000 FTU/kg bw/day).

^**significantly different from control, at P < 0.01.
