Plain-English summary
This study looked at the issue of twin pregnancies in horses and how giving extra progesterone, a hormone, might help prevent abortions in these cases. The researchers found that giving progesterone to three pregnant mares during the second half of their pregnancy seemed to help them carry their twin pregnancies to term. In the end, each mare delivered one healthy twin and one mummified fetus, which is a fetus that didn’t develop properly. Overall, the treatment appeared to be effective in preventing abortion of the viable twin.
Abstract
Equine twinning, related abortion and progestogen plasma concentrations during the gestation period were reviewed. The supplemental administration of exogenous progesterone apparently prevented impending twin abortions in three mares after midgestation. A single viable twin and a mummified fetus were delivered at term by the mares.
