Termination of midterm pregnancy in mares using intra-allantoic dexamethasone
Wichtel, JeffreyEvans, L. E.Clark, T. L.
Elective termination of midterm pregnancy was successful in four mares using a single intra-allantoic infusion of dexamethasone solution. Duration of gestation in the experimental animals ranged from 167 to 174 days. All mares responded within 72 h, with a mean of 53.5 h from treatment to abortion. Fetal death occurred in utero probably 24 h before abortion. All mares exhibited oestrus by day 16 post treatment and were bred, with three mares conceiving at this oestrus..
