What are the signs of lameness in pigs?

Lameness in pigs is a common issue that can significantly impact their welfare and productivity. Identifying the signs of lameness in pigs early is crucial for effective management and treatment. These signs include changes in gait, reluctance to move, and visible swelling or wounds on the limbs.

Understanding the signs of lameness in pigs is essential for prompt intervention. Here are some key indicators:

• Altered Gait: Pigs may exhibit an uneven or limping walk, favoring one leg over others.
