^a,bmeans in the same column within a main effect, 2-way interaction or treatment means with different superscripts are different (P < 0.05).

AB = Salinomycin 60 ppm in S, G, F; Zn bacitracin 100 ppm in S, G and 50 ppm in F.

Phy = Phytase (Quantum Blue 5G).

2 or 3-way interaction separated by Tukey.
