Abstract:
Temperament is a habit or emotional expression in response to the environment pattern in beef
cattle. The behavioral expression can develop and change depending on the learning environment and
each individual's experience, resulting in an emotional state. Habits are expressed through different
behaviors. This is a major physical factor that affects the production and yield of beef cattle. Temperament
testing using the Chute test and Exit velocity techniques can indicate each cow's emotion and character.
This study used 28 Kamphaengsaen beef cows, the first Chute test, and Exit velocity in the next step. The
cows were tested 4 times, divided into 1. before PGF2α injection 2. before artificial insemination 3. before
pregnancy examination, and 4. after pregnancy examination. Temperament test data of cows were grouped
into 2 groups calm cattle (n=13) and ill-tempered (n=15). The differences were significant (P< 0.01).
Correlation between the Chute test and the Exit velocity in the cows' classification was to be correlated
(r=0.873; P <0.01). Measurement of cows temperament using the Chute test and Exit velocity techniques
can identify the groups of calm tempered and ill-tempered emotions, which is the motivation for behavioral
