Effect of strogenic Hormones on Lactation in the Cow

Abstract

THERE is evidence¹ that administration of ” stro-genic hormones to lactating animals causes inhibition of milk secretion. In the case of the work cited, largely owing to the difficulty of making accurate measurements of milk secretion rate and of changes in milk composition in experiments on small animals, the evidence that inhibition occurs is not so conclusive as might be desired, nor have accompanying changes in milk composition been studied. The above difficulties are obviated by use of the lactating cow as experimental animal.
