Classification of temperament based on exit velocity effect on body weight (WT), chute scores (CS), individual animal exit velocity (EV), rectal temperature (TEMP), blood lactate (BLAC), serum lactate (SLAC), salivary (SCORT) or serum (BCORT) cortisol and serum glucose (GLUC)

Significance = *P < 0.05, **P ≤ 0.01, ***P ≤0.001, **** P ≤ 0.0001.
a,b,cMeans within a row that have a different superscript letter differ (P < 0.05).
1Exit velocities were separated by thirds with fastest exit velocities being classified as fast, slowest exit velocities as slow and the middle one-third classed as medium.
2Chute Scores – 1 = Docile, 2 = Restless, 3 = Nervous, 4 = Flighty (Wild), 5 = Aggressive, 6 = Very Aggressive.
