The research of efficiency of electrometric method of estrus detection in cow compared to visualclinical method has been conducted. It is found that from using the electrometric method, 72.2% of cows were fertilized after the first and second insemination, 61% – from using visual-clinical method. Money expenditure of insemination of fertilized cows of the experimental group amounted to 5516 UAH, of control group – 9715 UAH. The economic damage from the shortage of calves and milk in the experimental group was 4550 UAH., and 20580 UAH., respectively, the control group had 6300 and 29460 UAH of the economic damage.
