The trial involved 42 cows with clinical milk fever. Thirteen heifers and 32 cows without symptoms served as controls. Calcium, oestradiol and oestrone concentrations in serum were determined in blood samples taken within 6 h before or after parturition. Serum oestradiol and serum calcium concentrations correlated negatively. There was no association between oestrone and calcium concentrations. The results suggest that oestradiol plays a role in the aetiology of milk fever.
该试验涉及42头患有临床乳热的奶牛。13头小母牛和32头无症状奶牛作为对照。在分娩前或分娩后6小时内采集的血样中测定血清中的钙、雌二醇和雌酮浓度。血清雌二醇和血清钙浓度呈负相关。雌酮与钙浓度之间没有关联。结果表明，雌二醇在乳热的病因学中起作用。
