^a,bMeans with different superscripts within the same column differ significantly (P < 0.05).

¹Each value represents the mean of 6 replicate cages with 6 chicks per cage (n = 6).

²Each value represents the mean of 18 replicate cages with 6 chicks per cage (n = 18).

³Each value represents the mean of 24 replicate cages with 6 chicks per cage (n = 24).

⁴Probability values for main effects of ANOVA.
