Hoof lesions have been reported as the main cause of dairy cattle lameness (90%) in most studies. Depending on geographical area claw horn or dermal lesions are the main lesions of the hoof. Current study has been done on 2 dairy farms consist of 2900 milking cows (1800 milking cow in dairy no one and 1100 milking cow in dairy no two, the average of milk production for both herds were recorded as 36 lit/ day). Study have been done during 12 month from October 2006- Oct0ber 2007. Data from 5338 trimmed cows in farm 1 and 4080 trimmed cows from farm two have been analyzed during study. All new cases of sole ulcer and white line disease have been analyzed in according to reported trimmers\' data. One hundred and sixty two cases of sole ulcers recorded in farm one (9%) and 125 cases of white line disease recorded in farm two (6.94%). Annual incidence of 15.94% recorded for these two lesions. In farm two, 56 cases of sole ulcer (5.09) and 208 cases of white line disease (18.9%) with annual incidence of 24% for both diseases have been recorded. Overall incidence of 7.51 for sole ulcer and 11.48% for white line disease has been recorded. Results show the annual incidence of 19% for these two lesions in current study. Claw horn lesions are the main cause of the lameness in this area that in a high producing dairy farm needs proper diagnosis and treatment of the lesions. Low rate of culling from lameness in these herds shows proper diagnosis and treatment despite of its relatively high incidence. Special attention should be made to higher incidence of white line disease in this current study.
