BD, basal diet; PhyA, BD supplemented with Aspergillus niger 3-phytase, Finase^® P; PhyE1, BD supplemented with Escherichia coli 6-phytase, Quantum^®; PhyE2, BD supplemented with E. coli 6-phytase, Quantum^® Blue.

^a–d Mean values in a row with unlike superscript letters were significantly different (P ≤ 0·05; Fisher's protected least significant difference test). Mean separation was only computed if the overall F test was significant.
