a
Groups were least-ADG steers (n = 8), with the least average daily gain, and greatest-ADG steers (n = 8), with the greatest average daily gain, with groups having similar dry matter intake.
b
AUC = area under the curve calculated by receiver–operator characteristic curve analysis.
c
FDR = false discovery rate p-adjustment.
