Abstract:
Early detection of lameness in sows is important to reduce losses and improve animal welfare. Mild-to-moderate lameness is difficult to diagnose in sows. Infrared thermography (IRT) was evaluated as a method of detecting signs of inflammation in the lower limbs as an aid in lameness detection.
