Factors affecting the cervical mucus crystallization, the sperm survival in cervical mucus, and pregnancy rates of Holstein cows

Original language description

The objective of this study was to determine the relationship between calving year and season, parity, number of AI, day of lactation, milk production in the 1st 100 lactation days or diseases occurrence (retained placenta, endometritis or cysts), spermmotility (SM) during 30, 60 and 90 minutes of the cervical mucus survival test, cervical mucus crystallization (CMC) and their infl uence on days to first insemination (interval), open days (SP), inseminations number for pregnancy (index), and pregnancyrates (PR) in Holstein cows (n=284). Significant differences of interval, SP and index were detected also in relation to number of AI and day of lactation (P < 0.001). Cows without reproduction diseases (healthy) had better results of interval, SP (P < 0.01), index and PR. Pregnancy rate of healthy cows was by 11.43% higher, but without statistical signifi cance. The higher results of PR (62.74%) were discovered in relation to ferny-like crystallization of cervical mucus (P < 0.001). CMC
