x̄: period mean.

For each drug, the values within the same poultry production with different superscript lowercase letters in a row are significantly different (P < 0.05).

^ABFor each drug, the values within the same year with different superscript capital letters in a row are significantly different (P < 0.05).

^abFor each drug, the mean values of each poultry production with different superscript lowercase letters in a row are significantly different (P < 0.05).
