Urinary Oestrogens in Heifers Treated with Prednisolone During the Oestrous Cycle

Abstract

Heiferis treated with a glucocorticoid during the oestrous cycle, displayed increased follicular activity and small corpora lutea compared to untreated controls (Tomasgard 1976a), but showed no signs of oestrogen production during the treatment.
