THE POSTHATCH PHYSIOLOGY OF THE TURKEY POULT .2. HEMATOLOGY

1. Packed cell volume, total leukocytes, total erythrocytes, hemoglobin, mean cell volume and mean corpuscular hemoglobin concentration of the poult were analyzed daily for the first 10 days posthatch. 2. Sexually dimorphic effects on hematological parameters were not apparent, but there was a sex .times. day interaction for all parameters except hemoglobin indicating that males were slower to develop/respond to critical stimuli. 3. The study revealed a latency in production of erythrocytes and leukocytes in posthatch males and females which coincided temporally with early poult mortality.
