About Pigeon Fever
Pigeon fever is a bacterial infection that affects cattle and horses, causing large abscesses typically found on the chest and under the belly. The infection occurs when bacteria enters through open wounds or cuts on the animal’s skin, with the peak season for infections being late summer through fall.
Implementing good horse health safety measures is crucial in containing the spread of pigeon fever. These practices include:
- Effective fly control;
- Avoiding sharing water buckets or equipment; and
- Avoiding tying horses in busy areas.
If a horse owner suspects that their animal may be infected, it is important to contact a veterinarian for proper diagnosis and treatment.
