This current study was done during a 9 month period in a dairy cow with 2000 milking cows. Data of sole ulcers were recorded at first visit and each month after the first visit and the ulcer revealed treated when a layer of horny tissue covered the hole of the ulcer. Treatment was done by removing the horny tissue around the ulcer, using a wooden block on its contra sound digit. Also locomotion of the cows scored on a five point scale monthly and high score cows were inspected. Total of 69 ulcers recorded, as 57 (82.6%) cases were in rear feet. Total of treated lesions in three consequent month and also the number of culled cows were recorded in table 1. Untreated ulcers Days to final treatment Number of culled/ Percent Number of treated/ Percent Follow up month 25.03 ± 3.8 - 29/ 42.02 First 68.67 ± 14.09 7/ 10.14 23/ 33.33 Second 4/ 5.79 106.57 ±28.15 1/ 1.44 5/ 7.24 Third The average treatment time for sole ulcers recorded as 50.13 ± 28.94 days that ranged from 20 to 164 days, 5.79% of the cows that still got uncovered ulcers remained in the herd three month after treatment and total of 11.59% of the cows were culled during this period. Locomotion scores of the cows increased from three month before (2.68 ± 1.04), reach to the highest amount one month before (3.64±1.37), and decrease again till three month after recording the lesion (2.76 ± 1.23)(P<0.05). The average days in milk in affected cows was 250 days and treatments were more successful in cows with days in milk 300 and higher (P<0.05). No significant changes were recorded in milk production three month before to three month after detection of the lesion (P>0.05).
