a–dMeans within the same row with different letters are significantly different (P < 0.05).
1Treatment groups (n = number of birds per group): C, control group; PQ, the group received a basal diet and a 7 consecutive day injection of paraquat; PQ+PR, the group received a 7 consecutive day injection of paraquat and a diet supplemented with propolis; and PR, the group received a basal diet supplemented with propolis.
