Postnatal changes in hematology of the bat Antrozous pallidus

Blood oxygen capacity increases with growth as the result of increasing hemoglobin concentration, which is accompanied by increasing red blood cell count and hematocrit. Hematological profile of the postnatal bat approaches that of the adult by 42 days of age when the animal begins to fly. Hematological development in the bat is similar to that in other altricial small mammals.
