Popis: In spite of very strict breeding bull selection, especialy for A.I programes their infertility is a very serius problem in everyday practice. Especially bull semen has been marked as the main factor for unsatisfied cow fertility in the A.I.programme. The reason could be the bull semen which really may play as the spreading factor of the specific or non-specific reproductive infective disoders ? IBR, IPV, BVD, Campylobacter-Vibrio fetus, brucellosis leptospirosis, tuberculosis and other reproductive diseases. Secondarily, the percentage of vitality, motility, penetration abilities, and immonological properties of bull spermatozoa also have an important role in unsuccessful bovine fecundation. That is, why it is necessary to secure professional health care for breedig bull in AI centres, becase only healthy bulls can ensure good bovine genetic transmission and progress in cattle production for today's growing population.
