About Pigeon Fever
Pigeon fever is a bacterial infection that affects cattle and horses, causing large abscesses, typically on the chest and under the belly. Horses contract the infection through broken skin, like minor cuts or wounds, with peak season being late summer to fall.
Maintaining good horse health safety practices is crucial in preventing the spread of pigeon fever. These practices include:
- Implementing fly control measures;
- Avoiding sharing water buckets or equipment; and
- Not tying horses in busy areas.
If a horse owner suspects their animal may have pigeon fever, they should contact a veterinarian immediately.
