Factors affecting sperm survival in cervical mucus and pregnancy rates of Ovsynch-treated Holstein cows

Original language description

The objective of this study was to determine effect of insemination year, insemination season, parity, number of Al, days in milk, fat corrected milk production in the 1st 100 lactation days, disease occurrence (retained placenta, endometritis, or cysts)and their influence on sperm motility (SM) dutiny 30, 60 and 90 minutes of the cervical mucus survival test (n=381) or pregnancy rates (PR) in Ovsynch-treated Holstein cos (n=314). Insemination year had a significant effect on sperm motility (P < 0,0001). Significant differences related to the insemination season were determined dutiny the entire test time (P<0,05 to P<0,001). Cows inseminated from 15th May to 14th September demonstrated the lowest SM and PR, too. Highest sperm survival ability in primiparous cows (P < 0,05 - 0,01) was not confirmed by significantly Berger conception. No statistical significance was detected for the effect of the number of inseminations. Differences in SM in relation to numer of lactation days were sta
