Study was done in a dairy herd with 800 milking cows. The cows were trimmed on a regular basis in five groups. Cows were trimmed 120 days after parturition (Group I), immediately before drying off (Group II), High locomotion scored cows (Group III), reproductive delayed cows (Group IV) and visually detected cows (Group V). Incidence of sole ulcer as the most important non infectious claw disorder and Interdigital Phlegmone as the most important infectious claw disorder was recorded in each of the above mentioned group and compared descriptively. 5.76 & 1.02 % of cows in group I, 2.58 & 0.73% of cows in Group II, 24.32 & 5.85% of cows in group III, 5.4 & 0.9% of cows in group IV and 20.97 & 8.7 % of cows in group V showed sole ulcer in Zone 4 and Interdigital Phlegmone in Zone O of the hoof respectively. Results shows that in clinical normal groups like groups I, II and IV still some cows got the sever lesion in their digits. It is obvious that any of these lesions will make their economical losses and just by doing a general hoof trimming program, access to all lesions is possible. Otherwise farmer should wait until the injuries change to sever ones and changing the locomotion of the cow. In other hand locomotion scoring is not always the method of choice in detecting all lesions. More sole ulcers were detected by locomotion scoring; anyway this method was not as potent as visual detection in Interdigital Phlegmone. Maybe more severe nature of the later made it more prevalent among visually detected lesions.
