The article presents positive results of application of integrated ways (methods) of induction and synchronization of the sexual cycle in cows for wide practical application in accelerated (extended) reproduction of the herd cattle
Based on analysis of the etiopathogenesis of ovarian follicular cysts in cows and heifers we have developed a comprehensive method of treatment and prevention of them. Potassium iodide normalizes metabolism and has specific effects on the genitals, thyroid and pituitary glands, restores their function. Chlormadinone inhibits
the secretion of pituitary gonadotropins depending on the dose of the drug, and estrofan promotes growth of ovarian follicles and the manifestation of hunting and estrus in cows
The article gives mechanisms of the influence of the
main sex hormones on the sexual cycle of cows and
heifers and the effectiveness of their insemination. The
effectiveness of gonadotropin preparations releasing
hormone, prostaglandin and progesterone, used to
induce sexual hunting, was studied. The use of
combined use of hormones and prostaglandins is
effective for synchronizing sexual hunting, regardless
of the stage of the sexual cycle on which healthy
animals can be at the time of their administration. The
reasons for the retention of the yellow body in the
ovary are very diverse. The results of the studies
indicate that a particularly close relationship exists
between the yellow body and the uterus
