Covariates appearing in the model are evaluated at the following values for Milk cortisol of Model 1: DIM = 159.57, Milk, kg/d = 31.30; F1 to F10 farm 1 to farm10, se standard error, DIM days in milking

^a, ^b on the same column denote significant differences for P < 0.05; ^A, ^B, ^C on the same column denote significant differences for P < 0.01; ^Ns: not significant
