Abstract
THE lactogenic activities of ovine prolactin and bovine somatotrophin have been investigated in several strains of inbred mice, and a spectrum of responses was reported1,2. Prolactin was lactogenic in all strains, with some variations in sensitivity encountered. On the other hand, whereas somatotrophin showed considerable activity on tissues from some strains, other strains were much less reactive, and a single strain was completely unresponsive to the lactogenic effects of this hormone.
