Lameness is the second most common reason for culling sows and gilts, and increases mortality and decreases welfare. Visual observations are usually used to assess gait, lameness, and leg and hoof health, which is subjective. More objective measures can include using kinetics with force plates, kinematics by assessing movement videos, and high-resolution floor mats. These are expensive options, so data loggers and analyzing lying position may be more feasible. Three techniques were compared: visual gait scores, kinematics, and postural behaviour. Kinematics was an expensive and time-consuming option. Gait scores and postural behaviour could be used on farm, but results can differ depending on the housing system used.
