title: Survival of pig embryos flushed from the reproductive tract immediately or two hours after slaughter of donors.
abstract: Four- to eight-cell embryos were collected from genital tracts of slaughtered gilts. Prepuberal donors were synchronized and superovulated by PMSG and hCG, inseminated and eventually slaughtered approximately 78 h after the expected time of ovulation. Genital tracts were flushed either immediately after slaughter (group A) or after 2 h storage at either 37 degrees C (group B) or 20 degrees C). Best results were achieved in group A, followed by group B and, by a wide margin, group C. Differences in viability of embryos became more evident with longer culture times.
