| Summary: | When compared with other domestic animals the equine species is that present the minors reproductive
indices. Besides some parameters of estrous cycle are variable to we consider each mare individually, what hinders the
reproductive handling, these females respond the alterations of seasonality, this fact limits in reproduction its potential.
Therefore, the uses of innovative reproductive biotechnologies and hormonal protocols have shown indispensable for the
producers who wish to increase the reproductive rate of this species. Hormontherapy has shown great efficiency in
handling the estrous cycle of these females. Thus, this literature review aimed to perform an update regarding hormonal
protocols used in the equine species. Dealt with the main hormones used to control the estrous cycle of mares, as
prostaglandin F2a (PGF2α), estrogens, progestogens, human chorionic gonadotropin (hCG), the gonadotropin-releasing
hormone (GnRH), equine pituitary extract (EPE), the purified equine follicle stimulating hormone (eFSH) and oxytocin. It
became evident that the knowledge of hormontherapy applied in equine reproduction is of utmost importance, allowing
higher profitability by improving the reproductive efficiency of animals of high genetic value, generating benefits for both
