Introduction
Lameness is an important economic problem resulting in loss of milk production, reproductive failure and premature culling. Herdsmen often underestimate lameness prevalence because they become desensitized to lameness or fail to understand its production consequences (Wells, 1993). Ward 1994, found herdsmen and farmers are generally unable to identify early lameness but that on the other hand knowledgeable farmers had significantly less lameness. Lameness scoring is yet to become a widely used management tool in the US dairy industry. One of the reasons is that many dairy operations lack good facilities to adequately deal with lameness problems. Another reason is that lameness-scoring systems in general are subjective based on biomechanical alterations in posture and gait and behavioral changes causing interobserver variation...

Currently, a variety of locomotion scoring systems are used to assess lameness, few of these systems have correlated the score assigned to a cow with lesions in her hooves. The objective of this project was to evaluate the association between locomotion scoring and lesions found at the time of hoof trimming...
