Least squares means of exit velocity (EV) on each day of temperament assessment (d −8, 0, 1, 15, 29, 56, and 58) by EV treatment (slow or fast). Treatment was based on initial measures of EV (average = d −8). The initial average EV for the slow treatment was 1.74, and initial average EV for the fast treatment was 3.56 (n = 192). There was a significant EV by day interaction (P < 0.01). Points with different letters on a given day are significantly different (P < 0.01). The time effects of the slow EV treatment were characterized by linear (P < 0.01) and cubic (P < 0.01) effects. The time effects of the fast EV treatment were characterized by linear (P < 0.01), quadratic (P < 0.01), and cubic (P < 0.01) effects.
