Abstract. The transfer of the herd reproduction system to a seasonal basis is necessary for the intensification of beef cattle breeding. Various schemes of estrus synchronization are used to obtain seasonal calving. Their common disadvantage is low fertilization from frontal insemination. A thorough analysis of hormonal ratios in induced sexual cycles is necessary to develop optimal synchronization schemes. The aim of the research was to study the dynamics of sex hormones in organism of Kazakh White-Headed heifers during estrus synchronization according to two schemes. Two groups of heifers of a mating age of 40 heads each were formed to achieve this goal. In the first group a double intramuscular injection of estrophan was used with an interval of 11 days, in the second group the Ovsynch scheme was used. The blood was tested for hormones before stimulation, two days before insemination and on the day of insemination. A more significant increase in follicle-stimulating hormone (FSH), estradiol and luteinizing hormone (LH) was in the blood of heifers with double injection of estrophan than with the Ovsynch scheme. Presumably, the decreased hormonal response to stimulant drugs is due to a stronger stress effect when performing the Ovsynch scheme. The fertilization rate of heifers in this group was 2.5% lower.
