Since 2001, we have performed research and development in in vitro fertilization (IVF) technology in cattle and currently work with an impressive network of licensed veterinarians to bring to you a unique tool for genetic advancement. Our technology is robust and consistent with one goal: healthy calves on the ground.
The Process:
Transvaginal Follicular Aspiration/Ovum Pick Up (OPU):
Oocytes (eggs) are collected from follicles in the ovaries by OPU by ultrasound guide. In our experience, the average recovery rate is about 85% of follicles per cycle/aspiration or an average of 15 oocytes (eggs) per session. Strategic synchronization and ovarian stimulation is key to success.
In Vitro Fertilization:
Oocytes are placed with desired semen, with approximately 75% of the oocytes fertilizing.
Presumptive embryos are placed in culture in a highly controlled incubator for six to seven days. Our blastocyst rates consistently average around 50% or 5.6 embryos per aspiration (cycle).
Embryo Transfer:
Fresh IVF embryo transfers generally averages 52% pregnancy rate at 60 days of gestation in virgin dairy heifers and beef recipients and 50% in lactating dairy cattle, however, variability is expected depending on the inherent fertility of the donor, bull used for IVF, the recipient herd, and other factors such as heat stress.
Frozen IVF Embryo - Direct Transfer:
IVF Embryos can be frozen for direct transfer; however, expect a reduction of 5-10% in pregnancy rates when compared with fresh embryo transfer.
