| Abstract: The use of B-mode and color Doppler ultrasonography may replace the use of surgical methods (laparoscopy or laparotomy) in the evaluation of the superovulatory response in sheep, with an accuracy around 74% and 82%, respectively (Oliveira et al. 2018. Reprod Dom Anim, 53:742-750). The ultrasound determination of ovarian response in embryo donor goats still needs to be proven, especially because the non-invasive technique is mandatory when the embryo collection is done by transcervical route. The aim of this study was to correlate the quantification of corpora luteal (CLs) determined by Bmode ultrasound evaluation with the number of recovered structures obtained by transcervical embryo collection of superovulated goats. In view of the above, it is... |

| Abstract: The aim of this study was to determine the intervals between sponge removal and the onset of estrus, sponge removal and the first detected ovulation, and onset of estrus and the first ovulation, and also to determine the duration of estrus, in superovulated Santa Inês ewes subjected to natural mating (NM) and AI. The trial was done in July and February at Cachoeiras de Macacu?Rio de Janeiro (22°27'S, 43°39'W). Fifteen non-pregnant Santa Inês ewes, age 3.4 ± 1.4 years, weighing 47.8 ± 6.3 kg, with 3.3 ± 0.4 body condition score (scale of 1 to 5), were randomly assigned to 2 groups. Both groups were superovulated using the same protocol and were mated in a crossover design by NM and laparoscopic AI. Estrus was synchronized using intravaginal... |

| Abstract: The compatibility between the embryo development stage and the estrous cycle moment of the embryo recipient is an important factor in the multiple ovulation and embryo transfer (MOET) program. This aspect contributes significantly to the pregnancy establishment. Thus, the present study aimed to evaluate the effect of estrus synchronization and superovulation protocol on the distribution of ovine embryos at different stages of development. In conclusion, the protocol of estrus synchronization and superovulation was efficient in the synchronization of ovulation, which reflected in the prevalence of embryos in the stage of compact morula, when the collection is performed between days D6 and D7 after the first natural mating. This time relative do... |

| For the success of an embryo transfer program, it is necessary to achieve a great synchronization between the embryo donor and recipients. For this, hormonal protocols are commonly used, aiming at a greater number and quality of the viable products, in a shorter period of time. The aim of this study was to assess the effect of the hormonal protocol of estrus synchronization and superovulation in goats on the quality and stage of embryos obtained. In conclusion, the hormonal protocol used for superovulation of goats was effective enough to guarantee embryos in adequate stages and quality for fresh embryo transfer and cryopreservation, avoiding both undesired very young and hatched embryos. [Efeito do protocolo de superovulação sobre a qualidade e estádio de... |

| Abstract: Multiple ovulation and embryo transfer (MOET) is one of the most interesting reproductive biotechniques to be used in order to allow a rapid progression in the number of offspring per female. However, it is an underutilized reproductive biotechnology due to the variability of superovulatory response found and the high cost (Baldassare e Karatzas, 2004. AnimReprod Sci, 82/83:255-266). Brazilian naturalized breeds have socio-economic regional importance, but there is no studies reporting the effectiveness of in vivo embryo production on these animals. Thus, the aim of this study was to assess the efficiency of superovulation and viable embryo yield in Canindé and Moxotó goats raised and managed in different places. It is concluded that the in vivo... |

| The use of color Doppler ultrasonography in multiple ovulation and embryo transfer (MOET) protocols for sheep allows the real?time monitoring of ovarian blood flow and potentially can be a tool to predict embryo production in sheep. Therefore, the present study tested the correlation of ovarian vascularization at 36 h after the end of the superovulation treatment and at 12h (Day 15) before the non?surgical embryo recovery (NSER) (Day 16) with estrus response (ER%), duration of estrus (DE), number of corpus luteum (CL), number of anovulatory follicles (AF), number of structures recovered (SR), number of viable embryos (VE; Grade 1-3). |
