N.; WOHLRES-VIANA, S.; QUINTAO, C. C. R.; VIANA, J. H. M. Objective: In vitro maturation has been shown to influence gene expression in oocytes, but a common shortcoming in reports on the matter has been the use of different donors in each experimental group... ...

Oocyte quality in post-partum of 3/4 and 7/8 Holstein x Zebu primiparous crossbred cows. Author(s): CARVALHO, B. C. de; BRANDÃO, F. Z.; SANTOS, G. B.; VARAGO, F. C.; OTTO, P. I.; VARGAS, M. W.; GRÁZIA, J. G. V.; CAMARGO, L. S. de A. Repository: BDPA Publication year: 2013
Intraovarian injection of mesenchymal stem cells improves oocyte yield and in vitro embryo production in a bovine model of fertility loss. Author(s): MALARD, P. F.; PEIXER, M. A. S.; GRAZIA, J. G.; BRUNEL, H. dos S. S.; FERES, L. F.; VILLARROEL, C. L.; SIQUEIRA, L. G. B.; DODE, M. A. N.; POGUE, R.; VIANA, J. H. M.; CARVALHO, J. L. Valuable female cattle are continuously subject to follicular puncture (ovum pick-up - OPU). This technique is commonly used for in-vitro embryo production, but may result in ovarian lesion. Mesenchym... ... Repository: BDPA Publication year: 2020
Characterization of blood flow and the effects of exogenous estradiol benzoate on residual follicles formed after ultrasound-guided transvaginal follicle aspiration in cattle. Author(s): GHETTI, A. M.; SIQUEIRA, L. G. B.; ARASHIRO, E. K. N.; PALHÃO, M. P.; BRANDÃO, F. Z.; VIANA, J. H. M. Abstract Background: Removal of the follicular content by ultrasound-guided transvaginal follicle aspiration (TVFA) may fail to induce immediate atresia and loss of function, resulting in the occurren... ...

Performance of zebu donor cows in vitro production of embryos. Author(s): BECHER, B.; PINTO NETO, A.; GREGIANINI, H. G.; JELONSCHEK, J. P.; MOTA, M. F.; GREGIANINI, J. T. F.; CATTELAM, J.; MARTINEZ, A. C.; SOUZA, R. M. de; CARNEIRO JUNIOR, J. M. In vitro production (IVP) of embryos is a biotechnology capable of increase bovine production. Thus, the performance of Brahman, Gir, and Nellore donor cows in IVP was evaluated. Data from 2012 to 201... ... Repository: BDPA Publication year: 2020

T.; RAMOS, P. V. B.; BALIEIRO, J. C. C. Abstract: The objective of this study was to estimate variance components for oocyte and embryo production traits in Guzerá breed female donors, and investigate their associations with age at first ca... ... Repository: BDPA Publication year: 2016
