Comparison of oestrone sulphate concentrations in mammary secretions during lactogenesis and lactation in dairy ruminants

Extract
Oestrone sulphate is quantitatively a major oestrogen in pregnant goats rising gradually in concentration in milk and plasma as placental function develops (Heap et al. 1984). We report here that its concentration in mammary secretions increases sharply at the time of parturition. The results support the idea that oestrone sulphate in mammary secretions could be used as a predictor of the onset of parturition in dairy animals.
