TABLE 5.

Phytase activity (FTU/kg) recovered in the experimental diets.

Experimental diet	Starter phase	Grower phase	Finisher phase
Positive control (PC)	<50	<50	<50
PC + 0.30% inositol	<50	<50	<50
Negative control (NC)	<50	<50	<50
NC + 500 FTU	385	840	550
NC + 1,000 FTU	834	1,480	1,310
NC + 2,000 FTU	1,850	2,490	1,950

¹The phytase used was Quantum Blue (AB Vista, Marlborough, United Kingdom) with an expected activity of 5,000 FTU/g.
