The use of exogenous progesterone in sheep superovulation protocols influences the percentage of viable embryos. Author(s): TAIRA, A. R.; SANTOS, J. D. R.; COSENTINO, I. O.; BRAIR, V. L.; ESPÍRITO SANTO, C. G. do; PINTO, P. H. N.; SOUZA-FABJAN, J. M. G. de; FONSECA, J. F. da; UNGERFELD, R.; BRANDÃO, J. Z. The success of multiple ovulation and embryo transfer strongly depends on superovulatory protocols (SOV) success which has shown inconstant. SOV protocols have used different sources of progestogen wi... ... Repository: BDPA Publication year: 2020

Factors influencing in vitro embryo production. Author(s): CAMARGO, L. S. A.; VIANA, J. H. M.; SÁ, W. F. de; FERREIRA, A. M.; RAMOS, A. A.; VALE FILHO, V. R. In vitro embryo production (IVP) is currently one of the most important biotechnologies in cattle breeding and husbandry. However, the efficiency of in vitro embryo production is still low with only 3... ... Repository: BDPA Publication year: 2006
Cervical transposition test at estrus as a tool to select ewes for transcervical embryo collection. Author(s): SANTOS, J. D. R.; ARASHIRO, E. K. N.; BALARO, M. F. A.; SOUZA-FABJAN, J. M. G.; PINTO, P. H. N.; SOUZA, C. V.; ALFRADIQUE, V. A. P.; BADE, A. L. C.; FONSECA, J. F. da; BRANDÃO, F. Z. The use of multiple ovulation and embryo transfer (MOET) program in sheep is limited by anatomical particularities of ovine cervix, making non-surgical embryo collection method (transcervical) more di... ...

Superovulation and transcervical embryo recovery in Lacaune ewes raised under tropical conditions. Author(s): FIGUEIRA, L. M.; ALVES, N. G.; SOUZA-FABJAN, J. M. G.; BATISTA, R. I. T. P.; SOUZA, L. C.; MAIA, A. L. R. S.; BRAIR, V. L.; FILQUEIRAS, M.; SOUZA, G. N. de; FONSECA, J. F. da This study assessed two superovulatory treatments and the feasibility of transcervical embryo recovery in Lacaune ewes. Ewes (n=23) received medroxyprogesterone acetate sponges (60mg, Progespon®, Synt... ... Repository: BDPA Publication year: 2018

Improving postcryopreservation survival capacity: an embryo-focused approach. Author(s): SUDANO, M. J.; PASCHOAL, D. M.; MAZIERO, R. R. D.; RASCADO, T. S.; GUASTALLI, M. D.; CROCOMO, L. F.; MAGALHÃES, L. C. O.; MONTEIRO, B. A.; MARTINS JR. A.; MACHADO, R.; LANDIM-ALVARENGA, F. D. C. The major challenge for a greater dissemination of in vitro produced (IVP) bovine embryos is to improve embryonic survival after cryopreservation. The involvement of embryonic lipids on this issue is... ... Repository: BDPA Publication year: 2013
Efficient transcervical embryo collection in synchronous estrus-induced Lacaune ewes. Author(s): FIGUEIRA, L.; SOUZA-FABJAN, J.; BATISTA, R.; SOUZA, L.; DIÓGENES, Y.; FILGUEIRAS, M.; SOUZA, G.; ALVES, N.; FONSECA, J. F. da Induction of cervical dilation allows efficient non-surgical embryo recovery, depending on the sheep breed, and thus its usefulness needs to be assessed in each breed. This study checked the efficienc... ... Repository: BDPA Publication year: 2018
