Summary
This report details a rare case of polymelia in a Fayoumi chicken, documenting clinical and radiographic findings of extra limbs. Amputation of the supernumerary limbs proved to be an easy, safe, and curative procedure.
Area of Science:
- Veterinary Medicine
- Avian Pathology
Background:
- Polymelia, the presence of supernumerary limbs, is a rare congenital anomaly in avian species.
- Understanding its occurrence and management is crucial for veterinary diagnostics.
Observation:
- A 7-month-old layer Fayoumi chicken presented with two extra pericloacal limbs.
- These limbs were immobile, loosely attached, inverted, and fused proximally.
- Radiographic examination revealed variations in bone and digit development within the extra limbs.
Findings:
- The supernumerary limbs lacked muscles and tendons, appearing smaller than normal.
- Radiographs showed differing skeletal structures between the two extra limbs.
- The extra limbs had normal skin but underdeveloped feathers.
Implications:
- This case contributes to the limited literature on polymelia in birds.
- Successful surgical amputation offers a curative treatment option for affected poultry.
- Further research may explore the genetic or environmental factors contributing to avian polymelia.
