Oklahoma City, Oklahoma – Veterinarians at the Oklahoma State University Center for Veterinary Health Sciences center were shocked when a pregnant mare gave birth to twin mules. The mare, Sara, was recently adopted by a family, and gave them an incredible surprise.
Both little twins are reported as “being scrappy and improving daily.” The chance of survival for both twins during pregnancy, labor and birth is roughly 1% for horses.
Donkeys have significantly higher percentage of twins than horses. Roughly 1 in 100 sets of twins in donkeys will survive. Mares carrying mule twins are also more likely to successfully carry both mules through pregnancy than horse twins.
