^{a, b}–mean values in rows with different letters differ significantly at P<0.05; Data given are LSMeans; SEM–standard error of the mean

NC–the negative control group without received Zn in premix

Zn25%–the group received Zn in 25% of daily recommended dose from Zn-Gly

Zn25%+phyt–the group received Zn in 25% of daily recommended dose from Zn-Gly with phytase (500 FTU) inclusion

PC–the positive control group received Zn in 100% of daily recommended dose from ZnO
