The RFI of the most calm bulls (with temperament 1) was -0.83±0.67, and in bulls with a moderate temperament (temperament 2), this indicator was 36.5% less, that is, -0.53±0.55. The RFI of bulls with an excited temperament was 0.19±0.85, and in aggressive bulls, this indicator was 0.62± 0.86. It is noted that the calmer the bulls are, the lower the RFI and vice versa. The highest average daily increase was in bulls with temperament 1 (equal to 1,507 ± 0.06 g), and in bulls with temperament 4, the average daily increase was 1,191 ± 0.1 g, which is 20.97% lower than that of their most calm peers. However, the difference in the average daily gain between bulls with temperaments 3 and 4 was 70 g or 5.56%, respectively, in favor of bulls with temperament 3. The average daily gain of bulls with temperament 3 was 1,261± 0.09 g, which was 5.97% lower than that of calmer bulls. At the end of the test, the body weight of the calmer bulls was greater than that of their peers with the most aggressive temperament. In particular, the body weight of bulls with temperament 1 was 312.78a ± 4.44 kg, which is 12 kg or 3.9% greater than that of bulls with temperament 2, whose average body weight is 300.60ab ± 3.19 kg. The lowest average body weight was observed in bulls with temperament 4 (aggressive) – 291.48b±7.17 kg. 295.47b±6.70 kg. Bulls with a temperament of 3 were weighed and lagged behind their peers with a temperament of 2 by 5.13 kg.
