What clinical sign is commonly observed in cattle affected by crooked calf disease?

Crooked calf disease, also known as arthrogryposis multiplex, is characterized primarily by the abnormal curvature of the limbs, which is referred to as arthrogryposis. In cattle affected by this condition, you will typically observe deformities in the joints causing the limbs to be twisted or bent in unnatural positions. These deformities are a direct result of improper fetal development often caused by factors such as viral infections, nutritional deficiencies, or genetic factors during gestation. Therefore, the correct identification of arthrogryposis as a clinical sign of crooked calf disease is crucial for understanding the condition, its impact on calf development, and the management strategies that may be taken to address such issues in affected herds.
