In an internordic field study of the effect of the Ca dose (6, 9 and 12 g) on the therapeutic result in parturient paresis, considerably better results were recorded in Finland than in the other countries at all dose levels. In Finland a full effect was obtained with 6 g, while in all others 9 g Ca yielded a significantly better result than 6 g. Raising of the dose to 12 g produced no improvement. There was a significant difference in therapeutic results between the two Finnish breeds. A larger number of fatal cases was recorded among paretic cows with plasma Ca greater then 8.0 mg/100 ml.
在一项关于钙剂剂量（6克、9克和12克）对产乳热治疗效果影响的北欧地区实地研究中，在所有剂量水平下，芬兰记录的治疗效果都比其他国家好得多。在芬兰，6克钙剂就能取得完全的效果，而在其他所有国家，9克钙剂产生的效果明显优于6克。将剂量提高到12克并没有带来改善。芬兰的两个品种之间治疗效果存在显著差异。在血浆钙含量高于8.0毫克/100毫升的患乳热奶牛中，记录到的死亡病例数量更多。
