No successful non-surgical embryo collection has been reported in pigs so far,except the studies of Kobayashi et al. and Hazeleger et al. following surgical resection of uterine horns. The major reason of this restriction is the anatomy of the porcine genital tract. Therefore embryo collection can be performed in vitro by flushing the genital tract after slaughter, but this technique has the limit to use donor sows only once. Embryo recovery in swine is usually accomplished surgically under general anaesthesia, with the genital tract presented through a midventral incision in the caudal abdominal region involving retrograde flushing of the oviducts and/or uterine horns. The disadvantage of surgical procedures can be diminished by minimal-invasive endoscopic techniques to recover embryos.
