Effects of Supplemental Phytase and Xylanase on Phytate
Phosphorus Degradation, Ileal Protein and Energy
Digestibility of a Corn-soybean-wheat Bran
Diets in Broiler Chicks
Effects of supplemental phytase and xylanase in a corn-soybean meal based diet containing
250 g/Kg wheat bran, were investigated. on broiler performance and phosphorus
degradability and nitrogen digestibility. Phytase (500 and 1000 FTU) and xylanase (2700
and 5400 EXU) individually and in combination were added to the basal diet and given to
6 replicate groups (4 birds per replicate). At 21 days of age, birds were weighed and
killed , ileal contents were collected and analyzed for P, N, chromic oxide and gross energy.
Added phytase significantly (P<0.01) improved feed conversion ratio (FCR) (1.59 vs
1.62 g /g) and tibia ash (464.4 vs 444.3 g/Kg). Protein digestibility was increased (81.7 vs
79.4%) significantly (P<0.01) by 500 FTU/Kg added phytase. Supplemental xylanase significantly
(P<0.01) improved FCR (1.58 vs 1.63 g/g) and protein digestibility (82.0 vs
80.4%). Phytate P degradability was significantly (P<0.02) improved by added phytase
(41.4 vs 27.8%). Combination of supplemental phytase and xylanase had some beneficial
effects on improving the nutritive value of diets containing wheat bran for broilers.
