Overview
Perosis, commonly known as slipped tendon or chondrodystrophy, is a musculoskeletal disorder primarily affecting young poultry like chickens and turkeys. It results in leg deformities and mobility issues due to tendon displacement.
Causes
Perosis is often caused by nutritional deficiencies, particularly a lack of essential vitamins and minerals such as manganese, biotin, or choline in the diet. Genetic factors and rapid growth rates can also contribute.
Symptoms & Signs
Early Symptoms
- Slight lameness
- Mild swelling around hock joints
Advanced Symptoms
- Severe lameness
- Visible tendon displacement
Emergency Signs

Diagnosis
Diagnosis involves physical examination by a veterinarian, focusing on the affected limbs. Blood tests may be conducted to check for nutritional deficiencies.
Treatment Options
Home Care
- Providing a balanced diet rich in essential nutrients
