1. Premature expulsion of fetal material: The mare may expel the fetus, placenta, and fluids from the uterus. The expelled material may be visible as a reddish-brown discharge or clots.
2. Abdominal pain: The mare may show signs of abdominal discomfort or pain, such as restlessness, pawing at the ground, looking at her flanks, or lying down and getting up frequently.
3. Udder development: In some cases, the mare's udder may begin to develop and produce milk, even though the fetus is not viable.
4. Vaginal discharge: The mare may have a vaginal discharge that may be clear or tinged with blood.
5. Behavioral changes: The mare may become withdrawn, lethargic, or show reduced appetite.
It's important to note that not all cases of miscarriage in horses are accompanied by obvious signs. In some cases, the fetus may be reabsorbed by the mare's body, and the miscarriage may go unnoticed.
If you suspect your mare has had a miscarriage, it is crucial to contact your veterinarian promptly for proper diagnosis and management. The veterinarian will examine the mare, evaluate the expelled material, and determine the appropriate course of treatment.
