Ask the Vet: Foaling Injuries & Complications
25 February 2013
Question: I have a maiden mare due late April/early May that is coughing. I have had her scoped, which indicated she has mucus in her lower airway. Can the foal be putting pressure on the lungs and causing this mucus
In all likelihood, the cough is probably not related to pregnancy. While foals do take up a lot of room in the abdomen, especially during the last three months of pregnancy, this is not a primary cause of respiratory illness. However, if the mare is in a negative energy balance because the growing foal is requiring the majority of her calorie and energy intake, this can lessen the effectiveness of the immune system causing respiratory infection.
