Intrauterine Infusion of High Doses of Pig Trophoblast: MATERIALS AND METHODS(1)

Animal Management The experiment was carried out on cyclic Meishan gilts (n = 15) derived from the experimental herd of Institut National de la Recherche Agronomique (INRA)-PRMD (Nouzilly, France). The number of estrous cycles preceding the experiment ranged from one … Continue reading

Intrauterine Infusion of High Doses of Pig Trophoblast Interferons Has No Antiluteolytic Effect in Cyclic Gilts(2)

The situation appears clearer in domestic ruminants (sheep and cattle), in which the antiluteolytic factor, long known to be proteic [12], has been shown to be an interferon (IFN). IFNs are cytokines having antiviral, immunomodulatory, and antiproliferative activities. They comprise … Continue reading

Intrauterine Infusion of High Doses of Pig Trophoblast Interferons Has No Antiluteolytic Effect in Cyclic Gilts(1)

In most mammals, establishment of pregnancy requires the continuation of progesterone production by the corpus luteum (CL) beyond the luteal phase of the estrous cycle. In ungulates, this phenomenon relies on a signal delivered by the trophoblast of the periimplantatory … Continue reading
