With the purpose of evaluate the prevalence, clinically classify of digital lesions and estabilish score to lameness, 323 cows were examined in 63 proprieties located in the dairy basin of Belo Horizonte and Pedro Leopoldo, which 57 were semi-intensive system and 6 were intensive system. The prevalence of animal did not vary between the systems and multiple lesions predominated. The most prevalent lesions were bulb of the hoof erosion (59.8%), digital dermatitis (30.3%) and scissors hoof (24.1%). Digital dermatitis, bulb of the hoof erosion, hemorrhagic sole and scissors hoof were most frequent in pelvic members, while interdigital dermatitis and wall hemorrhage were frequent in thoracic members. No differences were found in the lesions distribution between the lateral and medial nails of each member. Score of lameness to animals with simple lesions was in average of 1.216 and to animals with multiple lesions of 1.828.
