The aim of this paper was to evaluate semen parameters from Czech Fleckvieh (dual-purpose breed) bulls used in artificial insemination in the Fleckvieh population. The ejaculate was collected from bulls only once a week, which is not usual. Respectively, the effects of age and season of collection on semen parameters were tested. The average volume of ejaculate by Fleckvieh bulls was 8.72 mL, which is higher than results in studies of bulls which were collected usually more than once a week. The average total motility was 72.82 % and progressive motility was 67.99 %. Sperm concentration reached on average . The total motility of spermatozoa after thawing was 40.88 %. A significant influence of age was observed on ejaculate volume, total and progressive motility, and total motility after thawing ( ). The season of collection had a significant influence on the volume of ejaculate, total motility, progressive motility, concentration of spermatozoa, and total count of spermatozoa ( ).
本文旨在评估捷克弗莱维赫牛（兼用型品种）用于弗莱维赫种群人工授精时的精液参数。精液采集仅每周从公牛身上进行一次，这并不常见。分别对采集年龄和季节对精液参数的影响进行了测试。弗莱维赫公牛的平均射精量为8.72毫升，高于通常每周采集多次的公牛的研究结果。平均总活力为72.82%，前进活力为67.99%。精子浓度平均达到 。解冻后精子的总活力为40.88%。观察到年龄对射精量、总活力和前进活力以及解冻后的总活力有显著影响（ ）。采集季节对射精量、总活力、前进活力、精子浓度和精子总数有显著影响（ ）。
