Changes in the blood constituents of reindeer and caribou occurring with age
Packed cell volume, hemoglobin, mean corpuscular hemoglobin concentration, reticulocytes, total leucocytes, and plasma protein concentration were measured each week throughout the year for six reindeer and six caribou. Red blood cells (RBC), packed cell volume (PCV), hemoglobin (Hb), and reticulocyt...

| Summary: | Packed cell volume, hemoglobin, mean corpuscular hemoglobin concentration, reticulocytes, total leucocytes, and plasma protein concentration were measured each week throughout the year for six reindeer and six caribou. Red blood cells (RBC), packed cell volume (PCV), hemoglobin (Hb), and reticulocyte numbers were lower in the reindeer than caribou, whereas the leucocyte concentrations were higher. Activity and excitement, part of the aggressive behavior displayed by rutting caribou, resulted in an increase of PCV, Hb, and plasma protein levels by 21%, 18.5%, and 10%, respectively. In female caribou, about an 8% drop in these value; occurred during estrus. From the fifth month of pregnancy to parturition, PCV, Hb, and plasma protein increased by 17%, 13.5%, and 11%, respectively. |
