Abstract:
The aim of the study reported here was to determine the radiographic appearance and morphometry of the digital region in culling lame cows. Present study was carried out on 43 samples of culled lame cows at an abattoir in the vicinity of Tehran. Cases were randomly selected and after recording information for individual cows, affected foot was amputated and carried to Veterinary Teaching Hospital Radiology Department for more routine radiological studies. In every case at least four radiographs were taken of lateral, dorsopalmar/dorsoplantar and two oblique projections. New bone formation, pedal osteitis and gas density were three factors considered for assessing the severity of the disease. Several radiographic landmarks were used to obtain measurements from each of the radiographs. Lameness was assessed by means of a visual locomotion score. For the highest new bone formation length, significant differences were observed between the dorsal and palmar/plantar surface of the proximal part of the P3 bone with other surfaces (p<0.05). For the deepest osteitis depth, significant differences were observed between the P3 bone and the other digit bones (p<0.05). For the greatest diameter of gas density, significant differences were observed between the P3 bone and the other digit bones (p<0.05). In the P3 bone, significant differences were observed between the lateral surface of proximal and distal part with other surfaces for any radiographic determination (p<0.05). In conclusion, application of radiography, especially in the cases of chronic and recurrent lameness, can play an effective role in deciding to continue the treatment or cull the animal.
