Study on the temperament of cows of the Aberdeen Angus cattle breed

The present study examined the temperament of 699 cows of the Aberdeen Angus cattle breed, reared in 14 farms in Bulgaria. It was carried out within the period 2017–2020. The animals subject to the study were between two and eight years old. The temperament was visually evaluated following a scoring system from 1 to 5. The assessment method involved the behavioural reaction of the cows upon manipulation, passing through a chute and fixation into a cattle crush. The temperament of cows reared in two different systems – intensive and semi-intensive farming was compared. The temperament of the Aberdeen Angus cows had an average rate of 2.74 ± 0.04. The cows which had frequent contact with people had a calmer temperament. The manner of rearing (P < 0.001) as well as the age group (P < 0.001) had a significant influence on the parameter examined. The young animals were calmer and got accustomed to working in a crush more easily when they were reared together with cows of different ages.
