FIELD: animal husbandry.
SUBSTANCE: method of increasing the fertility of cows from frontal insemination is characterized by the following: the cows are synchronized with sexual heat: on the 1st day, the first injection of the gonadotropin-releasing hormone “Surfagon” is administered intramuscularly to the cows at a dosage of 5 ml/head, on the 8th day the second injection is given of prostaglandin Ϝ2α "Estrophan" at a dosage of 2.5 ml/animal, on the 10th day the third injection — gonadotropin-releasing hormone "Surfagon" at a dosage of 5 ml/animal, with artificial insemination without detection of heat on the 11th and 12th days, and in this case, during the period of synchronization of sexual heat, cows are fed with krezacin together with grain feed at a dosage of 2 g/head daily for 10 days.
EFFECT: invention makes it possible to increase the number of fertilized cows during frontal insemination.
