Birth of a Live Cria After Transfer of a Vitrified-Warmed Alpaca () Preimplantation Embryo.

The alpaca () is an important species for the production of fiber and food. Genetic improvement programs for alpacas have been hindered, however, by the lack of field-practical techniques for artificial insemination and embryo transfer. In particular, successful techniques for the cryopreservation of alpaca preimplantation embryos have not been reported previously.
