The relationship of estradiol-17β concentration in blood serum with the efficiency of oocyte retrieval in cows of the Tagil breed
Aspiration of ovarian follicles (OPU) is the major source of oocyte retrieval for in vitro production (IVP) of embryos in cattle. The identification of donors whose OPU-oocytes have the better competence to embryonic development is of interest in terms of increasing the efficiency of oocyte retrieval and in vitro embry...
