About Pigeon Fever
Pigeon fever is a bacterial infection that can affect both cattle and horses, causing large abscesses, typically found on the chest and under the belly. Horses contract the infection when bacteria enters through wounds or cuts on the skin. The peak season for pigeon fever infections is late summer to fall.
Maintaining good horse health practices is crucial in preventing the spread of pigeon fever. These practices include:
- Implementing fly control measures;
- Avoiding sharing water buckets and equipment; and
- Not tying horses in areas with high traffic.
If a horse owner suspects that their horse may be infected, it is important to contact a veterinarian for proper diagnosis and treatment.
