About Pigeon Fever
Pigeon fever is a bacterial infection that impacts cattle and horses, causing large abscesses, typically on the chest and under the belly. Horses contract the infection when bacteria enters through open wounds or small scrapes. The peak season for pigeon fever infections is late summer through fall.
Implementing good horse health safety practices is crucial in controlling the spread of pigeon fever. These practices include:
- Fly control;
- Avoiding sharing water buckets or equipment; and
- Avoiding tying horses in high-traffic areas.
If a horse owner suspects their animal is affected, they should contact their veterinarian.
