To succeed in artificial insemination and to produce the fecundation in cows it isnecessary to have knowledge about optimal time of ovulation. Such possibilityappears using the values of electrical resistance of cervical mucus. The smallestvalues are obtained during the ovulation due to the pH modification influenced by theestrogens. The purpose of the paper was to determine the electrical resistance of thecervical mucus in cows with clinical signs of estrus, depending on females’ age. Also,the electrical resistance of the cervical mucus in cows in different physiologicalstages (pregnant, no pregnant) was measured. The ovulation detector DRAMINSKIwas used. This equipment allows to obtained a quickly and precise rapport on thephysiological stage of the cow. It can be detected the cow with atypical ovulation,irregular ovulation. This method improve the insemination efficiency, allowsdetecting early gestation period or the moment of ovulation. All these have a positiveinfluence on the development strategy of the farm and improve the economicperformances.
