The production of Santa Inês sheep in Brazil is very important to farmers because they are rustic, adapted to most part of gastrointestinal parasites and have good maternal ability (Sousa et al., 2003; Amarante et al., 2004). To maintain these characteristics, the animals are selected, and reproductive biotechnologies are applied to induce estrus with progestagens throughout the year, due to their seasonality. Different strategies of estrus induction and synchronization are used worldwide (Balaro et al., 2017) but, traditionally, intravaginal progestagen devices are often applied. One of the disadvantages of hormonal treatment is the cost itself. Currently, there are three different commercial brands in Brazil and overall, the cost of those devices is relatively high. Alternatives must be proposed in order to make efficient treatments, without adversely affecting the reproductive efficiency. Therefore, the aim of this study was to evaluate the efficiency of three protocols of synchronous estrus induction during the transition period in Santa Inês ewes.
