Locomotion Scoring System
Locomotion Scoring is
a system used to assess lameness that is based on the observation of sows
standing and walking. This system is intuitive and easy to learn and implement.
Use of locomotion scoring is effective
for early detection of foot disorders and lesions, monitoring prevalence of
lameness in a herd, comparing the incidence and severity of lameness between
herds and identifying individual sows for functional claw trimming.
Sow moves easily with
little inducement. She is comfortable on all her feet.
She moves relatively
easy, but visible signs of lameness are apparent in at least one leg. She is
reluctant to bear weight on that leg but still moves easily from site to site
in the barn.
Lameness is involved
in one or more limbs. The sow exhibits compensatory behaviors such as dipping
her head or arching her back.
There is a real
reluctance to walk and bear weight on one or more legs. It is difficult to move
her from place to place on the farm.
This locomotion scoring system was
developed by the Feet First® team. It uses a simple 0 to 3 scale to assess the
severity of lameness in sows.
Observations should be made on a flat surface and under conditions where the
sow is not stressed. Sows instinctively hide signs of lameness when they feel
