Eight Korean native black goats were used, $10m{ell}$ of blood was collected from the Jugular vein into heparinized tubes a week interval. The heparinized blood was centrifuged for separation to blood plasma and corpuscles. The hematocrit, per centage of blood that is red blood cells, was reschuffuled of 10 %, 20 %, 30 %, 40 % and 50 % using blood plasma, 0.9 % NaCl solution and 5.4 % dextrose solution. The sedimentation rates of red blood cell obtained at $7^{circ}C{pm}1^{circ}C$ and $27^{circ}C{pm}1^{circ}C$ are summarized as follows. 1) The sedimentation rates of red blood cell were more increased by lower PCV%, i.e. there was a reverse relationship between the sedimentation rates and PCV% at any condition of these experiments. 2) The RBC were sedimented the most quickly in the NaCl solution and slower in the plasma compare with the dextrose solution at the same PCV%. 3) There was no temperature effect on the sedimentation rates between the two groups of $7^{circ}C{pm}1^{circ}C$ and $27^{circ}C{pm}1^{circ}C$(at PCV 20% and 10%), even though the temperature difference is $20^{circ}C$.
