Since 1978, the current preferred and most common method to transfer cattle embryos into synchronized recipients is via nonsurgical techniques. The embryo is loaded into a small plastic straw (0.25 mL) fitted into a specialized (Cassou-type) pipette (ie, artificial insemination gun).

In farm animal embryo transfer, transferable embryos are embryos deemed of acceptable quality for transfer into recipient animals as fresh embryos or to be cryopreserved for future use. In 2018, in cattle, the number of transferable in vivo-derived (IVD) embryos produced in the world was ~470,000—less than half of transferable embryos ...
7 sie 2018 · Commercial embryo transfer in cattle has become a well-established industry. Although a very small number of offspring are produced on an annual basis, its impact is large because of the quality of animals being produced.
