Abstract
The administration of reserpine to nonlactating dairy cattle produces a marked increase in circulating serum prolactin levels. The parenteral administration of reserpine to nonlactating cows which have been hormonally induced into lactation, as by the parenteral administration of an estrogen and progesterone, and dexamethasone, results in a substantial rise in milk production.
