All ejaculates produced by individual bulls during the first three years were examined. There were 33103 ejaculate features of both bull breeds analysed. The following features were examined: total quantity of semen, number of ejaculates, mean volume of ejaculate, spermatozoon concentration, their survival rate and translatory motion. On the basi s of the investigations it wae stated that the kind of breed had no effect on either quality or quantity of the semen.
