Foot diseases are some of the main causes of low performance in dairy cows. In order to determine the prevalence, clinical classification and to establish the epidemio-logical factors of foot diseases in cows from basin milk of Rondon do Pará, 1,236 cows were evaluated and 275 had at least one type of foot injury. A total of 655 lesions was showed which a prevalence of 22.25%. Most frequent lesions were interdigital hyperplasia (80.92%), claw overgrowth (6.42%), and interdigital necrobacillosis (6.11%). Hind limbs were most frequently affected (61.83%), and lesions affecting the interdigital space were the most common in both the thoracic (36.34%) and hind limbs (48.09%). Epidemiological study showed that the environmental characteristics such as mountainous areas, newly formed grassland (with trunks and branches of trees), irregular ground, and mud and gravel in the floor of the pens may promote the development of foot lesions. In 95.5% of the farms, no measures had been taken for the control and prophylaxis of foot diseases. The specific clinical examination of the feet was efficient for the diagnosis.
