[QUOTE="Lorenzo, post: 603271, member: 5104"] You have a great cow without doubts. I have produce lots of flushed embryos also and in average a "meat" cow gives you aprox. 6 viable embryos and a dairy cow gives you 3 viable embryos. This is an average of our experience. Thanks God there are not much cows like yours out there because if not the IVF technology will dissappear.. :D The production of bovine in-vitro embryos (IVF), begins with follicular aspiration (OPU) conducted on the donor cow’s ovaries. Oocytes are collected from live animals by follicular aspiration of the ovaries, with the help of an ultrasound scanner. The OPU technique consists of aspirating oocytes contained inside the ovaries' follicles through aspiration by negative pressure. Ovaries are reached via the rectum and they are brought nearer to the cervix. A probe with an ultrasound guide is introduced all the way to the cervix and the ovary is then touched with the point of the transducer in order to visualize the follicles. The probe has a spindle containing the needle that is connected to the aspiration pump; the vagina wall is punctured with the needle and the follicles located on the dissection line are punctured in such a way that the oocytes contained inside the follicles may be aspirated. After aspiration of both ovaries, the collected material is transferred to the laboratory set up in the field, where the aspirated liquid will then be filtered. The resulting material is then placed on a peltri dish. With the help of a microscope and a pipette, the oocytes are separated from the liquid; then they are classified and packed to be transferred to the main laboratory. Once they reach the laboratory, the collected oocytes are placed in a maturity medium and an incubator during a 24-hour period until they can be fertilized in vitro. Seven days after fertilization, and after going through several changes in the culture medium, the embryos are ready to be transfered to receptor cows of low genetic value. If we aspirate a cow two times a month and it gives you aprox. 8 viable embryos pero month ergo 4 pregnacies per month. Lets stay in the safe side and say that you have 3 pregnacies per month without giving the donor a single hormone !! L [/QUOTE]
