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 get infected when bacteria enter through wounds or scrapes. The peak season for infection is late summer to fall.
Maintaining good horse health practices is crucial to prevent the spread of pigeon fever. These practices include:
- Fly control;
- Avoiding sharing water buckets or equipment;
- Avoiding tying horses in high-traffic areas.
If a horse owner suspects their animal is affected, they should contact their veterinarian.
