A total of 2160 samples of rib bone were used in a split-plot design analysis of variance to show that, on an ash weight basis, P content is not different among the right and left 9th, 10th, 11th, and 12th ribs of cattle above 6 mo of age. Results were similar for Ca on a fresh or dry weight basis. Some differences existed in Mg content among some of the ribs. Location on the rib from which samples were taken was responsible for significant differences in mineral concentrations. Based on results reported herein, ribs 9, 10, 11, and 12 of the right and left side may be used in the serial sampling of bone tissue in the bovine for the purpose of comparing the content of P, Ca, and--to some extent--Mg. Serial sampling makes possible comparison of bovine mineral status based on bone tissue over an extended experimental period that includes eight sampling dates.
总共2160份肋骨样本用于裂区设计方差分析，结果表明，以灰分重量计，6月龄以上牛的第9、10、11和12对左右肋骨的磷含量没有差异。以鲜重或干重计，钙的结果相似。部分肋骨间的镁含量存在一些差异。取样肋骨的位置导致矿物质浓度存在显著差异。根据本文报道的结果，左右两侧的第9、10、11和12对肋骨可用于牛骨组织的连续取样，以比较磷、钙以及在一定程度上镁的含量。连续取样使得在包括八个采样日期的较长实验期内，基于骨组织比较牛的矿物质状况成为可能。
