FIELD: animal husbandry.
SUBSTANCE: method of increasing the fertility of heifers during the synchronization of estrus and frontal insemination is characterized by the following: it includes the synchronization of estrus, which is carried out according to the following scheme: on the 1st day, the first intramuscular injection is given to the heifers — gonadotropin-releasing hormone "Surfagon" at a dosage of 4 ml/head, on the 8th day, a second injection — prostaglandin Ϝ2α "Estrophan" at a dosage of 2 ml/head, on the 11th day the third injection — gonadotropin-releasing hormone "Surfagon" at a dosage of 4 ml/head, with artificial insemination without detecting the heat on the 11th and 12th days, with additional subcutaneous injections for heifers a 20% aqueous solution of krezacin is injected at a dosage of 18 ml/animal on the 1st and 8th days of synchronization.
EFFECT: invention makes it possible to obtain a large number of calves in a favorable time frame.
