Embryos allow you to produce multiple calves from superior individuals utilizing a lesser valued surrogate female.
Bovine embryos can be stored indefinitely in a semen tank in liquid nitrogen. Remember you are dealing with one individual living entity and it can not stand temperature fluctuations while in the tank. Be very careful in handling.
Embryos are transferred into surrogate or recipient cows approximately 7 days after that cow was in heat. The embryo is placed deep into the uterine horn on the same side as she ovulated 7 days ago and a CL is now formed. That CL is responsible for progesterone production to establish and maintain pregnancy.
Cattle embryos are graded as 1, 2 and 3 quality grades with 1 being the best based on the morphology of the embryo’s cell mass.
Embryos should be bought from reputable breeders that utilize certified embryologists in the production of the embryos. Success is highly dependent upon the proper handling and cryopreservation of the embryos.
The actual technique by which the fertilized embryo is implanted into the uterus of an acceptable surrogate.
Cattle embryos can be sexed utilizing a biopsy after they are produced or through utilization of sexed semen during production.

You can certainly purchase embryos from breeders with a talent to produce animals with successful show career opportunity. Find breeders that show cattle or have their animals successfully shown by other breeders.
This is the actual process by which the embryos are removed from the donor female after a series of injections and breeding has occurred. Embryos are recovered approximately 7 days after breeding.
The most obvious advantage of transplanting embryos is the genetic improvement you can make by incorporating superior genetics into a surrogate or recipient female. The disadvantages would include the additional cost and labor of accomplishing the task.
There are protocols established for most countries that allow the importation of bovine embryos. It is necessary to use AETA certified embryologists to properly process the donor females and the embryos.
Buying embryos is a great way to acquire superior genetics. It allows you to get genetics from a great distance since shipping embryos cost much less than live animals. It also does so without risk of diseases being introduced into your herd.
The prices of embryos vary tremendously depending on the perceived value of the genetics you are purchasing. Quality embryos can be purchased any price from $200 to $2000 per embryo.
