The aim of the current research was to evaluate the effects that temperament has on
production and reproduction performances in Simmental dual-purpose cattle breed.
Behavioral reactivity of cows significantly influenced (P≤ 0.05) the body weight, milk yield,
fat yield, protein yield, protein content, and the calving interval of the cows included in the
study-head, having more substantial effects (P≤ 0.001) on the milking speed and the
number of steps per day, with calmer cows outperforming the nervous counterparts …
