¹Residual feed intake and residual average daily gain were restricted indices of ADDMI and ADG in which the weight on ADDMI or ADG, respectively, was set equal to 1 and the weight on ADG or ADDMI, respectively, was set equal to the negative of the genetic regression of ADDMI on ADG or ADG on ADDMI, respectively. All traits expressed in g/d of DM intake or BW gain.

²Breed effect estimates for all traits and indices as heifers were taken from Retallick et al. (2017).
