Erythropoiesis and erythrocytic survival in dogs with cyclic hematopoiesis.

Erythrocytic survival and ferrokinetic studies were carried out in dogs with cyclic hematopoiesis. The serum iron values varied during different phases of the cycle. The highest values occurred when the bone marrow predominantly contained granulocytic cells. The erythrocytic survival and the remainder of the ferrokinetic variables were comparable to those in normal dogs of a similar age.
