Summary
Multiple congenital anomalies in llamas are rare. This study reports a young llama with hind limb lameness, tibial tarsal bone rotation, valgus deformities, and a ventricular septal defect, likely hereditary.
Area of Science:
- Veterinary Medicine
- Genetics
- Comparative Pathology
Background:
- Congenital anomalies in South American camelids are documented.
- Multiple, concurrent anomalies are infrequently observed in this species.
Observation:
- A young llama presented with bilateral hind limb lameness.
- Physical examination revealed cranially rotated tibial tarsal bones.
- Additional findings included bilateral carpus and tarsus valgus and a ventricular septal defect.
Findings:
- The observed anomalies, including limb deformities and cardiac defect, suggest a complex congenital condition.
- The pattern of multiple anomalies points towards a potential hereditary basis.
Implications:
- Affected llamas with multiple congenital anomalies should not be included in breeding programs.
- Understanding the genetic basis of these anomalies is crucial for camelid welfare and breeding management.
