Artificial induction of lactation in ewes: the use of prostaglandin

Injections of an anlogue of prostaglandin F2alpha (T.F.101) initiated secretion of copious amounts of fluid resembling normal ovine milk when given to non-pregnant ewes with developed mammary glands. Injections of T.F.101 elicited a substantial but transient increase in the levels of prolactin in plasma. Results for intact and ovariectomized ewes were similar.
