¹ ADG₁ is calculated by the linear regression of BW on days on test. ² ADG₂ is calculated by (final BW − initial BW)/days on test. ³ All regression coefficients were statistically different from 0 where p < 0.005. ⁴ All Pearson correlations were statistically different from 0 where p < 0.005. ⁵ All Spearman correlations were statistically different from 0 where p < 0.0001. ⁶ All regression coefficients were statistically different from 0 where p < 0.05. ⁷ All Pearson coefficients were statistically different from 0 where p < 0.05. ⁸ All Spearman coefficients were statistically different from 0 where p < 0.005.
