Variation in the phosphorus content and specific gravity of bone samples taken from the 11th, 12th and 13th ribs of cattle was examined in relation to the selection of a site for the acquisition of such samples by biopsy, in experiments where changes in skeletal phosphorus storage required to be monitored. The degree of mineralisation of the 11th rib was significantly higher than that of the 12th, which in turn was greater than that of the 13th. It was concluded that valid comparisons may be made between bone samples obtained during an experimental regime, provided they are taken from the same numbered rib; it is recommended that the 13th rib be avoided in such studies.
在需要监测骨骼磷储存变化的实验中，研究了从牛的第11、12和13根肋骨采集的骨样本的磷含量和比重变化，以确定通过活检获取此类样本的合适部位。第11根肋骨的矿化程度明显高于第12根，而第12根又高于第13根。得出的结论是，在实验过程中获得的骨样本之间可以进行有效的比较，前提是它们取自相同编号的肋骨；建议在这类研究中避免使用第13根肋骨。
