Embryo Transfer Surgery via Laparotomy in Gilts.

This protocol aims to demonstrate the surgical technique for transferring cloned pig embryos to the oviduct, a method widely used in the production of genetically modified pigs for biomedical research. Nine gilts underwent hormonal synchronization and laparotomy for the transfer of cloned embryos produced by somatic cell nuclear transfer (SCNT) at stages of up to 4 cells on day 2 to the oviduct. Gestational diagnosis was conducted via ultrasound examination 30 days post-transfer surgery.
