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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
