Generally cervical mucus penetration test (CMPT) have been used for assessment of semen quality. In this study, a simplified CMPT was applied to evaluate quality of cervical mucus of cows in estrus using semen of proven fertility. Viscosity, pH, spinnbarkeit, cellularity, crystallization and penetration, were measured. A significant positive linear correlation was found between sperm concentration [Sp] detected in mucus after CMPT and the quality of each mucus samples according to physical characteristics. Comparing [Sp] values of cyclic cows with those of pathologic ones, we obtained higher [Sp] for cyclic cows respect to the pathologic cows. The evaluation of [Sp] could be useful to improve the diagnostic framework of bovine fertility.

RELATIONSHIP BETWEEN SPERM PENETRATION SCORE AND CERVICAL MUCUS QUALITY DURING ESTRUS IN COW

Abstract

Generally cervical mucus penetration test (CMPT) have been used for assessment of semen quality. In this study, a simplified CMPT was applied to evaluate quality of cervical mucus of cows in estrus using semen of proven fertility. Viscosity, pH, spinnbarkeit, cellularity, crystallization and penetration, were measured. A significant positive linear correlation was found between sperm concentration [Sp] detected in mucus after CMPT and the quality of each mucus samples according to physical characteristics. Comparing [Sp] values of cyclic cows with those of pathologic ones, we obtained higher [Sp] for cyclic cows respect to the pathologic cows. The evaluation of [Sp] could be useful to improve the diagnostic framework of bovine fertility.
