Measurement of the amount of fat in femoral bone marrow can provide a quantitative assessment of the nutritional status of an individual animal. An analytical method is presented for quantitating the percent fat in bone marrow from three domestic species: bovine, canine, and equine. In this procedure, fat is extracted from bone marrow using pentane, and the percent fat recovered is determined gravimetrically. Based on analyses from adult animals (normal body condition scores), the average percentage of fat in the bone marrow was >80%. In cases in which animals have been diagnosed as emaciated or exhibit serous atrophy of fat (body scores of 1 or 2), the femoral bone marrow fat was less than 20%. In domestic animals, bone marrow fat analysis can be a useful, quantitative measure that, when used in conjunction with all other data available, can support a diagnosis of starvation or malnutrition.
测量股骨骨髓中的脂肪含量可以对个体动物的营养状况进行定量评估。本文介绍了一种用于定量分析三种家养动物（牛、犬和马）骨髓中脂肪百分比的分析方法。在此过程中，使用戊烷从骨髓中提取脂肪，并通过重量法确定回收的脂肪百分比。根据成年动物（身体状况评分正常）的分析结果，骨髓中脂肪的平均百分比>80%。在动物被诊断为消瘦或出现脂肪浆液性萎缩（身体评分为1或2）的情况下，股骨骨髓脂肪含量低于20%。在家养动物中，骨髓脂肪分析可以作为一种有用的定量测量方法，与所有其他可用数据结合使用时，可以辅助诊断饥饿或营养不良。
