Occurrence of twin foals is very rare among horses, about one in 10,000 cases. And even though female horses do get pregnant with twins, owners are mostly suggested to abort one of the twins in order for a healthy birth. According to the veterinarians, if a mare is pregnant with twins it would be hard to save both of them. Even when in pregnancy, there won’t be enough space for both of the foals and will result in complications and most of the times death. So to prevent this, experts suggest owners to abort one and give other one a healthy life.
