Implication

Experimental study demonstrates live births following non-surgical embryo transfer in sows, indicating the feasibility of transcervical delivery for in vitro-produced blastocysts.

Key Points

To assess whether piglets can be produced by non-surgically transferring in vitro-derived blastocysts into recipient sows using a flexible catheter.
Oocytes collected from slaughterhouse ovaries were matured in NCSU-37 medium, fertilized in vitro, and cultured in porcine zygote medium-5 (PZM-5) to the blastocyst stage.
Without sedation, 45 to 50 blastocysts were transcervically transferred via a flexible catheter into the uterine horn of six synchronized recipient sows (N=6) 5 days after human chorionic gonadotropin (hCG) injection.
One of the six recipients became pregnant (16.7% pregnancy rate) and farrowed at 119 days after hCG administration.
The litter consisted of seven total piglets, including four live piglets with birth weights ranging between 0.8 and 1.4 kg.
