title: Lactate formation by the avian lung tissue.
abstract: The activities of formation of lactate and pyruvate were studied along with the development of chickens, Gallus domestica. In the lung the activity of lactate formation was highest in the embryo at 13th to 16th days of incubation, then the activity decreased as the development went on and continued to decrease even after the hatching. The change of the activity of pyruvate formation was almost parallel with that of lactate formation. On the other hand, in the liver the activities of formation of lactate and pyruvate remained constant and did not show such changes as observed for the lung.
