文摘

Phytase degraded IP6 phytate by >90% in the gizzard. Phytate degradation in the gizzard was related to performance. Phytase increased recovery of sodium along the small intestine. Sodium digestibility coefficients were positively correlated to starch digestibilities. Sodium digestibility coefficients were positively correlated to protein digestibilities.
