| Popis: | The aim of this work was to estimate the effect of vaccinating stallions against anthrax on the sperm quality and its criostability. Vaccination of stallions against anthrax led to a decrease in the sperm quality. During the first week after vaccination, the sperm productivity decreased by 10%. In freshly diluted sperm, the sperm motility decreased by 12%, survival by 38% (Р > 0.99), and membrane integrity by 20% (Р > 0.95) on average. Their recovery was observed not earlier than 28 days after vaccination. Vaccination had an especially strong effect on sperm quality after cryopreservation: sperm motility decreased by 35% (P > 0.99), survival by 45% (P > 0.99), and membrane integrity by 46% (P > 0.99) on average, and these parameters remained low for 1 month. Rejection of sperm doses in the postvaccination period was 50% because of the decrease in quality below the standard level. The amount of pathological types of sperm increased 45 days after vaccination: by 27% (Р > 0.95) in fresh sperm and 34% (Р > 0.99) in deconserved sperm. In the case of cryoconservation of stallions' sperm, it is necessary to take into account the recovery period after antiepizootic measures. |
