Abstract
The aim of this research was to investigate the influence of the bull age on production and some semen quality traits. The semen was collected during 2014. The LSD test (Least Significant Difference) was used to compare the bulls of different age groups and the results of this test showed in some cases significant differences. This test showed that there was no significant difference in ejaculate volume between six-year-old and four-year-old bulls, but in two-year-old bulls a significant difference to older bull groups was determined. The results showed that there was a significant effect of the bull age (p<0.001) on the ejaculate volume and the number of doses per ejaculate.
