Oestrogens and Milk Fever — is there a Link?
Östrogen och puerperal pares - finns det ett samband?

Abstract
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.
Sammanfattning
Undersökningen bestod av 42 kor med klinisk pares. Tretton förstakalvare och 32 kor utan kliniska symptom utgjorde kontrollgruppen. Koncentrationen av kalcium, östradiol och östron i serum uppmättes inom 6 t före till 6 t efter kalvningen. Inget samband melian koncentrationerna av östron och kalcium kunde påvisas, däremot förelåg en negativ korrelation mellan serum östradiol och serum kalcium.
Resultaten tyder på att östradiol kan spela en roll i den puerperala paresens etiologi.
