This cross-sectional and descriptive study was carried out on 43 samples of culled lame cows with digit disorders which were collected from slaughterhouse. After recording information for each cow, at least four radiographs were taken from amputated limb. New bone formation, osteolysis, soft tissue swelling and gas density were indices considered for assessing the severity of the disease. The prevalence rate of claw lesion among all cases was 69.7 per cent. Most lesions were mainly due to the effect of non-infectious lesions such as toe ulcer (3; 6.9 %), white line disease (5; 11.6 %), heel ulcer (6; 13.9 %), abaxial groove lesions (7; 16.2 %) and sole ulcers (9; 20.9 %), respectively. There were 20.5 % and 79.5 % cows with locomotion scores of 4 and 5, respectively. The most prominent radiographic abnormalities were noted in the P3 region of culling lame cows: widened vascular channels (23.2 %), extensor process entheseophyte (62.7 %), flexor tuberosity entheseophyte (65.1 %), osteolysis at the tip of the pedal bone (9.3 %), osteolysis of the plantar tuberisity (58.1 %) and abaxial wall (6.9 %), chip fracture (2.3 %), pathologic fracture (18.6 %), symmetric swelling (23.2 %), asymmetric swelling (69.7 %) and gas density into the claw (9.3 %). Septic arthritis and increase in joint width (18.6 %), bony ankylosis and subluxation (13.9 %) were noted in the Joints. In conclusion, radiography revealed the extent of osseous changes in cattle affected with laminitis, provided valuable additional information and confirmed the diagnosis and prognosis where a normal clinical examina¬tion seems inadequate.
