In the conditions of the Republic of Belarus there was realized a determination of an optimal time for cow insemination with the help of oestrus detector by Draminsky's method. In course of the experiment there were used black-and-white nonpregnant cows at the stage of oestrus (sexual heat). In course of the study there were used clinical, biochemical and hematological research methods. Dynamics of changing of estrous cycle slime depending on a day of sexual cycle was analyzed. Indexes of the reproductive function of cows in experimental and control groups were compared. Research results showed that revelation of cows with oestrus with the help of oestrus detector by Draminsky's proved to be efficient and informative. Insemination of animals at the stage when the resisting of oestrus mucilage after the minimal indexes (180-200) rose sharply up to the indexes 300-320 proved to be efiicient. This made it possible to realize single insemination of animals.
