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.
对70头奶牛的70份骨活检样本进行了生化分析和放射检查。通过对取自髋结节的骨活检样本进行生化检查，我们发现87%的受检奶牛存在骨质疏松过程，57%存在骨软化过程，51.4%存在骨质疏松/骨软化的联合形式。根据病理结果在繁殖周期各阶段的分布情况，发现产犊后奶牛的病理结果发生率最高。对骨灰中骨营养矿物质钙和磷含量的检测表明，只有5.7%的奶牛生理关系正常，87.2%的奶牛比例增宽，7.1%的奶牛比例降低。通过将生化检查结果与放射检查结果进行比较，我们发现放射检查方法在识别病理病例方面的差异低23%。骨活检样本的放射检查方法可用于代谢性骨病诊断的筛查。
