J Vet Pharmacol Ther 23: 359-363 Other limitations of ultrasonography in this context include minimal accessible evaluation location, and the possible need for repeated evaluation. The majority of mares will have a CTUP 12 mm at the time of foaling and a CTUP >15 mm in horse mares and >12 mm in pony mares after 310 days of gestation is associated with placental malfunction. For example Sulfa drugs can create gastro-intestinal problems in the mare, while Gentamicin remains longer in the fetal compartment than in the mares circulatory levels and prolonged use can damage the foals kidneys.
