Six male pigs (Goettingen) aged 11 months were allotted to a 6X6 Latin square design. Pigs were fed a diet containing a sufficient amount of phosphorus (P-sufficient diet) or a phosphorus deficient diet (basal diet). The basal diet was supplemented with 0, 1,000, 2,000 or 4,000 phytase unit (PU)/kg of yeast phytase, or 1,000 PU/kg of Aspergillus niger phytase. Apparent absorption of phosphorus was increased (P0.05) by the supplementation of 2,000 and 4,000 PU/kg of yeast phytase. Although phosphorus absorption in pigs given 1,000 PU/kg of Aspergillus niger phytase did not differ significantly from those given 2,000 PU/kg of yeast phytase, the pigs given 1,000 PU/kg of Aspergillus niger phytase tended to absorb more phosphorus than did the pigs given 1,000 PU/kg of yeast phytase (P
