Erythropoiesis in the dog: the periodic nature of the steady state.
In at least six of 11 normal dogs serial measurement of reticulocyte counts showed oscillation with a period of approximately 14 days. The phase of oscillation could be altered by bleeding followed by retransfusion. The observations suggest that canine erythropoiesis is an example of a physiological rhythm which has its origin in homeostatic control.
