The objectives of the present study were: a) to evaluate the consistency of temperament traits of primiparous F1Holstein - Gyr cows throughout time and across distinct handling situations (milking temperament and handlingtemperament in the corral), and b) to assess the relationships between temperament traits and milk yield. Themilking temperament was characterized by the movement of the hind legs (number of steps and kicks), inaddition to recording the frequencies of defecation, urination, rumination and kicking offthe milking cluster, aswell as recording individual daily milk yield. To evaluate handling temperament in the corral, the following datawere recorded: ET (entrance time, time to walk along the single-file race and enter the squeeze chute); CS (crushscore, assessing the reactivity within the squeeze chute, in scores from 1 = no movement to 4 = frequent andvigorous movements); FS (flight speed); FD (flight distance) and NOT (novel object test, recording latency for theanimal to interact with an unfamiliar object). The number of steps during milking was negatively correlated withET (r =−0.285; P < 0.01) and positively with FS (r = 0.355; P < 0.01), FD (r = 0.245; P < 0.05) and NOT(r = 0.283; P < 0.05), indicating that the animals which took a greater number of STEPS during milking werefaster to enter and exit the squeeze chute, kept a greater distance from the observer and were more cautious tointeract with the novel object. In turn, the frequency of kicking offthe milking cluster was positively correlatedwith ET (r = 0.230; P < 0.05) and CS (r = 0.322; P < 0.01), but negatively with NOT (r =−0.386;P < 0.01), indicating that the animals that kicked offthe milking cluster were more reactive in the chute andhad a greater disposition to interact with the novel object. Milk yield was negatively correlated with the numberof KICKS (r =−0.244; P < 0.05) and positively with the rumination (r = 0.324; P < 0.01). Rumination wasthe only behavioural trait with effect on the milk yield (F2,78= 4.02; P < 0.05). The temperament of crossedHolstein-Gyr dairy cows was consistent over time and through the different handling situations and milkingtemperament traits were associated with milk yield, unlike handling temperament.
