متن کاملOvum pick-up in cattle: a 25 yr retrospective analysis
Repeated oocyte collection by transvaginal ultrasound-guided follicular puncture (Ovum Pick-Up: OPU), implicitly associated to in vitro embryo production (IVEP), has become alternative and competitive to superovulation for embryo production in cattle. It is alternative because it can be applied successfully irrespective of the reproductive status of the donor, i.e. in pregnant and acyclic anima...
