Embryo transfer can happen in many different animals including humans. Many people do not know that most farmers do embryo transfer because they use their dominant genetics in order to produce dominant offspring. Embryo transfer is not only better on the economic side such as costs of transferring eggs from cow to cow but the offspring you get from the egg will improve your herd and bring in more profit. Some transfers of preimplantation embryos occur in laboratories/vet offices due to fact that embryos from donor females cannot be immediately put in recipient females after harvest due to there may not be any recipients. So the alternative to this is to cryopreserve (freeze) the embryos so that they can be transferred at a later date. Another alternative that is done in laboratory settings is the possibility to produce preimplantation embryos in vitro. Many embryos are frozen within nitrogen tanks or semen tanks which many cattle owners have with dealing of semen used for artificial insemination. The process of embryo transfer all starts with the selection of a donor cow that’s going to help produce the most genetically superior offspring for the future. A donor cow is a cow that has an excellent sire and dam background, typically needs to be docile which means very calm when around humans, structurally correct in her body structure, and has proven that she produces offspring that suites the needs wanted by the cattle market. Typically a selection for a donor cow is taken place based on three types of information about the cow. The first source of information comes from the animal’s pedigree. The animals pedigree show the sires and dams of the animal for multiple generations and also helps to show if there is any defects foun... ... middle of paper ... ...ound 60 percent or greater which is very good. From personal experience, the best that my family has had is 80 percent of the transferable embryos stick when we do embryo transfer. The results that were shown are dead on accurate. Knowing that this process takes an entire day to flush the embryos, checking them out under a microscope, and transferring them into a recipient cow, it is well worth the money and time spent in the end. Yeah typically it cost $250 per egg to be transferred into just one recipient not knowing whether the egg sticks or not but I felt that it is well spent money in the long run once the calf is born and sold later on.
