Table 5. Effect of diets supplemented with different amounts of phytase on carcass parameters of broilers 35 days after hatching¹.

Item	CON	LPY	HPY	SEM2	P value
Carcass weight, %	74.34	71.91	71.06	1.330	0.792
Breast muscle weight, %	26.21	24.98	25.37	0.500	0.250
Thigh muscle weight, %	5.49	5.97	5.75	1.560	0.127

¹Values are the mean of six replicates per treatment (N=270)

²Pooled standard error of mean

CON: control diet (phosphorous-sufficient diet with dicalcium phosphate)

LPY: phosphorous-deficient diet with 0.01% phytase (500 FTU/kg) without dicalcium phosphate

HPY: phosphorous-deficient diet with 0.02% phytase (1000 FTU/kg) without dicalcium phosphate

^{a, b}Means in the same row with different superscripts differ significantly (P<0.05).
