- Abstract
The goal of this study was to determine the effect of phytase on true total tract digestibility of phosphorus (TTDP) and endogenous losses of phosphorus (ELP) of full-fat rice bran (FFRB) by simple linear regression. Twelve castrated pigs in the growing phase with an average live weight of 57.00 ± 2.50 kg were used. The experiment lasted 36 days, divided into three periods of 12 days each. The experimental design consisted of randomized blocks in a 2 × 3 factorial scheme, with two levels of fungal phytase (0 and 750 FTU kg-1) and three levels of phosphorus (P) coming from FFRB (5%, 10%, and 20%), totaling six treatments with six replicates. The P coming from FFRB recovered in feces was influenced by phytase (P < 0.008) and by the amount of ingested FFRB (P < 0.001). The average value of ELP was 524 mg/kg dry matter intake (DMI). The TTDP of FFRB was increased by 20 percentage points due to phytase addition. In conclusion, the ELP represented 524 mg/kg DMI on average. The addition of 750 FTU of phytase increased the TTDP of FFRB, which was 32.60% and 52.60% without and with phytase, respectively.
