Lymphangitis, while less common than some other health concerns in horses, is a serious condition typically prevalent in horses that have been put to heavy work. There are instances where a difference in the animal’s routine, such as resting for a day or more while still on a full working ration, contributes to the development of this disease.
This article aims to give a comprehensive overview of lymphangitis, its symptoms, treatments, and prevention methods to better address this health issue in horses.
Symptoms of Lymphangitis
Usually, one hindleg is affected by lymphangitis, although there are rare instances where a foreleg is impacted. The most telling sign of the disease is a severely swollen limb, often reaching up to the groin. This swelling is accompanied by acute lameness, indicating the animal is in considerable distress.
Not only is the limb tender and painful, but the horse typically also suffers from fever and exhibits signs of lethargy. You may even notice the horse acting “sorry for itself,” demonstrating visible discomfort. In some cases, serum, a substance similar to plasma, may leak from the inflamed leg, indicating a more intense level of inflammation.
Treatment: Medication and Movement
Addressing lymphangitis often requires a multifaceted approach, integrating both medicinal and physical solutions. Medications commonly used include antibiotics to combat any underlying infection, diuretics to reduce fluid buildup, and anti-inflammatory and pain-killing drugs to manage inflammation and discomfort.
Pairing this medicinal approach with the physical act of movement often proves quite effective. Encouraging walking exercises, usually several times a day, helps stimulate circulation in the affected areas, thereby helping to reduce swelling.
Prevention: Adjusting Diet and Exercise
Preventing lymphangitis mostly involves an accurate understanding of the horse’s routine and needs. The key lies in managing their rations relative to their workload. On days without any work, it’s crucial to cut back on the concentrate ration. If feasible, allowing the horse to roam outdoors can significantly help maintain their health.
This balance between diet and exercise is fundamental in preventing lymphangitis. Each horse’s rations need daily adjustment based on their workload, ensuring that they are neither overfed nor undernourished on any given day. Remembering these simple practices can help keep your horse healthy and lymphangitis-free.
