Embryo transfer in swine.
Embryo transfer is used to propagate genetically superior swine while minimizing disease risks. Embryos are harvested through a ventral midline incision in the anesthetized sow 4-6 days after estrus, using a glass tube or Foley catheter. Embryos are transferred to similarly prepared sows by injection directly into the uterus through a tomcat catheter or glass pipette. Embryos typically are transferred within a few hours of collection but may be stored in culture medium at 37 C for up to 30 hours.
