Results from a field investigation involving 1086 cows with clinical milk fever, revealed a clear relationship between PCV at the time of first treatment and the subsequent course of the disease. Average PCV was progressively higher as the cows required one, two, or more than two treatments before recovery, and was highest in cows which subsequently failed to recover. PCV in healthy, periparturient cows was considerably lower than in cows with milk fever. PCV was negatively correlated with plasma Ca, and varied, moreover, with the time of first treatment in relation to calving, and also with the length of time the cow had been recumbent before being treated for the first time. PCV was also measured during the further course of the disease in cows which received more than one treatment (2nd to 6th treatments).
一项涉及1086头临床患乳热症奶牛的现场调查结果显示，首次治疗时的红细胞压积与疾病的后续病程之间存在明显关联。随着奶牛在康复前需要接受一次、两次或两次以上治疗，平均红细胞压积逐渐升高，在随后未能康复的奶牛中最高。健康的围产期奶牛的红细胞压积明显低于患乳热症的奶牛。红细胞压积与血浆钙呈负相关，此外，还随首次治疗时间与产犊时间的关系以及奶牛首次治疗前躺卧的时长而变化。在接受多次治疗（第2至6次治疗）的奶牛疾病进一步发展过程中也测量了红细胞压积。
