چکیده مقاله:
A5.2 year-old Holstein cow was presented with lameness and abnormal weight bearing in a slaughterhouse. Widening of the periople and swelling of the heel area in the lateral claw was more permanent than the medial claw. Vertical fissure (VF) involving the coronary band to the middle of the dorsal wall of the medialhind claw was observed. It was also extended to the bearing surface in the inner surface of the claw wall. White line disease 2 (WLD2) was seen in the length of VF on the bearing surface. The horn of the bulb apex of the lateral hind claw was hypertrophic. There was a groove in the footpad between the apex and base of the bulb too. Grosspathologically, the digital bones showed a wide range of bone changes such as new bone formation, pedal osteolysis and bony ankylosis. The hind leg was amputated at the tarsus immediately after slaughter. The lower limbs of lame cows were examined and the type and distribution of digital lesions were tabulated. An x-ray machine was used in this study to take radiographic images. The radiographic images taken from the involved digits of the affected case depicted a quite wide range of radiographic signs. After the first review of the X-ray film, samples were selected for further procedures through putrefaction. Laminitis may have affected this case at some previous time. Routine trimming seems to have prevented the premature culling in the cows with claw lesion.
