1Offered into all of the models (i.e., odds of milk consumption, time to starter consumption, rate of starter consumption, total starter consumption over the 8-wk study, water intake, rate of BW gain, total BW gain over the 8-wk study, BW at weaning, and time to weaning).
2Offered into the generalized linear mixed models only (i.e., odds of milk consumption, rate of starter consumption, water intake, and rate of BW gain).
