¹Reported estimate derived from the interaction models with Zn × C × D and the covariates of BW on d 0 and sex.

²Comparisons derived from the model with C × D, D, C, and Zn as fixed effects.

³Comparisons derived from the model with Zn × C × D as fixed effects.

⁴Comparisons derived from the model with D as fixed effect.

^opqIndicate difference (P ≤ 0.05) within the column (comparison between the days within group).

^abIndicate difference (P ≤ 0.05) between Zn concentrations (150, 1,400, and 2,500 ppm) within challenge group.
