Gastrointestinal obstructions are common in horses. Blockages can occur in any part of the digestive tract and can cause sharp and severe pain. These obstructions can stop the flow of food through the digestive tract and, in some instances, impair blood flow or cause damage to intestinal tissues. Broodmares may be predisposed to obstructions, especially during pregnancy and shortly after giving birth. Standardbred stallions and colts develop inguinal and scrotal hernias more commonly than other breeds
