The aim of the study was to analyse the ejaculate of ten breeding bulls using high quality analyzer of spermatozoa motility HTN, version 7. Final analysis determined 26.0 - 62.0% of spermatozoa with progressive motility. Path velocity of spermatozoa ranged from 31.0 -87.0 micro m./s, straightness of spermatozoa was 73.4 - 84.5%. Analysis of feeding dose showed a low content of nitrogenous compounds, a high level of fibre, an unbalanced ratio of calcium to phosphorus and a high level of cadmium. Net-energy of fattening in feeding dose exceeded 20%, nitrogenous compounds more than 30% and fibre 40%. Generally it can be summarized that in the selected breeding station the level of nutrition was good. The ejaculete of breeding bull was of good quality with some insignificant individual differences
