In vitro technologies related to pig embryo transfer.

Embryo transfer in swine (ETS) has been used for commercial and breeding application only to a limited extent. However this technique is an essential prerequisite for the application of new reproductive techniques in pigs. This paper will give an overview on steps of pig embryo transfer including selection and stimulation of donor sows, recovery of embryos, embryo handling and the transfer of recovered embryos into recipients. Furthermore the current status and further application of ET related in vitro technologies in pig production are described.
