B-mode ultrasonography evaluation of superovulatory response in Brazilian native goats. Repositório Alice
VERGANI, G. B.; LIMA, M. S. D.; TEIXEIRA, D. I. A.; SILVA, K. de M.; MONTEIRO, A. W. U.; RAMOS, A. F.; BATISTA, R. I. T. P.; FONSECA, J. F. da; OLIVEIRA, M. E. F..
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...

Resumo: A caprinocultura é uma atividade relevante na pecuária brasileira, de grande importância em todo mundo e o uso de biotecnologias da reprodução pode contribuir para aumentar a eficiência produtiva e reprodutiva dos rebanhos. As técnicas de superovulação (SOV) e transferência de embriões (TE) são utilizadas na multiplicação de material genético superior nessa espécie, porém, a carência de informações estatísticas limita a estimativa do impacto potencial das mesmas. Diante disso, o objetivo do presente estudo foi realizar um levantamento de trabalhos científicos relacionados à produção de embriões de caprinos produzidos no Brasil entre os anos de 1985 e 2018 e identificar tendências no desenvolvimento dessa biotecnologia no país. Observa-se que, no...

Correlations between biometrics parameteres and vascularization of corpora lutea and serum progesterone concentration in superovulated sheep. Repositório Alice
BEVILAQUA, J. R.; RODRIGUEZ, M. K.; MACIEL, G. S.; VERGANI, G. B.; FONSECA, J. F. da; OLIVEIRA, M. E. F..
In vivo embryo production performs an important role in small ruminants, however the efficiency of this biotechnology has high variability. In this context, the occurrence of luteal dysfunction is exacerbated in superovulated females (Rodriguez et al., 2015) and it is an unwanted response wich may be related to low embryo production. Thus, it is possible to highlight the need to expand knowledge related to the corpora lutea functionality, as well as determinative tools for ultrasound diagnosis. The aim of this study was to test correlations between biometric variables, luteal vascularization and serum progesterone concentrations. In conclusion, luteal vascularization is an indicative of corpus luteum functionality in superovulated ewes.

Abstract: The objective was to evaluate if supplemental LH given at the end of FSH treatment would synchronize the time of ovulation and increase the ovulation rate and embryo yield in Santa Ines ewes. Twenty superovulatory (SOV) programs were accomplished in cross-over design (60d interval). On D0, a CIDR device was inserted, and the device was replaced with a new one 7 days later, when 37.5µg of d-cloprostenol was administered. On D12, we started the SOV treatment, administering 256mg of pFSH 8 times, 12h apart. On D14, the CIDR was removed, and 200IU of eCG and 37.5µg of d-cloprostenol were administered. On D15, the ewes were allocated into one of two groups, a Control group (n=10) that received no supplemental LH and a LH group (n=10) treated with...

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.

The effects of feeding urea on embryo production, quality and developmental stages and follicular status at the beginning of a superovulatory treatment of Toggenburg does fed urea diet were investigated in this study. Eighteen females were randomly allocated to receive diets with: no urea (control, n=8), and 2.4% urea dietary dry matter (n=10) UDM. The embryo recovery was performed at day 7 or 8 of estrus cycle by transcervical technique and classified according to quality and developmental stage. The follicular status was determined by transrectal ultrasonography at the first day of FSH injection. The number and quality of embryos were not affected by dietary urea concentration. Embryos from does treated with 2.4% UDM were recovered at advanced stage....

Ten multiparous non-lactating cows were randomly assigned to one of two groups. On days 8 to 12 after estrus, the first group was given 100 ml antiserum against steroid-free bovine follicular fluid (anti-bFF), which was produced in ovariectomized sheep. The second group (control) was given 100 ml nonimmune ovariectomized sheep serum. Six hours after injection, both groups were superovulated with FSH (18 NIH-FSH-S1 units) and LH (0.29 NIH-LH-S1 units) in a 4-day decreasing regime. On the morning of the third day a luteolytic dose of prostaglandin F2alpha analogue (cloprostenol) was given. Artificial inseminations (AI) were done 48 and 60 h later. Embryos were collected 7 days after AI by a nonsurgical method. Blood samples were taken throughout the...
