[Diagnosis of osteopathy in cattle using bone biopsy].
Seventy samples of bone bioptates from 70 cows were examined by the biochemical analysis and radiographically. By biochemical examination of bone bioptates taken from the tuber coxae we demonstrated the osteoporotic process in 87% of examined dairy cows, the osteomalacic process in 57% and the combined form, i.e. osteoporosis/osteomalacia in 51.4% of examined dairy cows. According to the distribution of findings in relation to the phases of reproduction cycle, the frequency of pathological findings was found to be highest in cows after calving. The examination of ash for the content of osteotrophic minerals, calcium and phosphorus, has demonstrated the physiological relation in 5.7% of dairy cows only, widened ratio in 87.2% and reduced one in 7.1% of dairy cows. By a comparison of the biochemical finding with the radiographic one we have revealed the difference, by 23% lower, in identification of pathological cases by the radiographic method. The method of radiographic examination of bone bioptates can be used as screening in the diagnostics of metabolic osteopathies.
