| This study evaluated the efficiency of non-surgical embryo recovery (NSER) with cervical relaxation protocol using different doses of estradiol benzoate (EB) in ewes. A total of 36 pluriparous Dorper ewes received intravaginal sponges containing 60 mg of medroxyprogesterone acetate (Progespon®, Zoetis, Brazil) for 9 d plus an injection of 300 IU of eCG (Novormon®, Zoetis, Brazil) i.m. 24 h before sponge removal. |

| Abstract: This study checked the effectiveness of ranking the difficulty to clip/traction and traverse the cervix with the Hegar dilator as a predictor method for selecting suitable animals to undergo NSER. A total of 46 pluriparous Santa Inês received intravaginal sponges containing 60 mg medroxyprogesterone (Progespon®, Syntex, Buenos Aires, Argentina) during six days plus 200 IU eCG (Novormon 5000®, Syntex, Buenos Aires, Argentina) i.m. and 37.5 ?g d-cloprostenol (Prolise®, ARSA S.R.L., Buenos Aires, Argentina) latero-vulvar 24 h before sponge removal. This grading system may indicate the probability of individual animals to successfully proceed with NSER. It is suggested that a selective system for donors should include an attempt to... |

| Abstract: The variability of superovulatory responses is still a limiting factor for the consolidation of commercial embryo transfer programs in small ruminants (Bartlewski et al. 2016. Theriogenology, 86: 130-143). Superovulation protocols are traditionally performed with prior use of progesterone devices for short- or long-term duration (Oliveira et al. 2014. Anim Reprod Sci, 144: 30-37) associated exogenous FSH administration. The presence of dominant follicles in the ovary at the beginning of FSH treatment is detrimental to the growth of the other follicles, in addition, a greater number of antral follicles is required to have a bigger superovulatory response (Fonseca et al., 2010 Acta Sci Vet, 38: 337-369). In this context, the objective of this study... |

| Abstract: Ewes have certain particularities in the cervical anatomy leading to the commercial use of surgical methods for collecting embryos in this species. However, the literature shows that Non-Surgical Embryo Recovery (NSER) is possible through specific protocols for cervical relaxation (Fonseca et al., 2019. Reprod Fertil Devel, 31:17-26). The cervical ostium may have several classifications: flap, duckbill, rosette, rose, spiral or papilla. This study aimed to assess the influence of cervical ostium anatomy on the difficulty of traversing cervical rings. In conclusion, the current data suggest that the morphology of cervical ostium may have influence on the success of embryo collection by Non-Surgical Embryo Recovery (NSER) technique.

| Twenty-five Canchim heifers (24.2±0.5 months and 383.4±26.2 kg) were allocated in the pasture at full sun (PS, n=13) or with afforestation (iLPF, n=12). Each animal received a cervical electronic device to monitor its behavior during 94 consecutive days. Animals kept in PS remained idle for longer during morning and afternoon, which coincided with the highest BGHI values registered. Meanwhile, heifers of ILPF presented more active. Thus, the lowest BGHI recorded in shaded areas was one of the possible determinants for behavioral changes evaluated with the use of the electronic system of monitoring. |

| Abstract: Despite the importance of Morada Nova for Northeast sheep production systems, information about embryo production of this breed is scarce with only one report of multiple ovulation and surgical embryo recovery (Brasil et al., 2016. ArqBrasMedVetZootec, 68:1390-1394) and non-surgical uterine access (Fonseca et al., 2016. Theriogenology, 86:144-151). In this context, the objective of this study was to evaluate the efficiency of different superovulation protocols in pluriparous Morada Nova using nonsurgical embryo recovery (NSER) to access embryo production.
