Relative Anticipated Erythrocyte Sedimentation Rate of Cattle Blood, as Measured by 45 Degree-Angled Wintrobe Hematocrit Tube, for Ambient Temperature and PCV Value

Each of twenty blood samples taken from apparently healthy Korean cows was used to produce five different mixtures of autologous plasma and blood corpuscles such that their values of packed cell volume(PCV) lay between 10 to 50ml/100ml. The measurement of erythrocyte sedimentation rate (ESR) using 45 degree-angled Wintrobe hematocrit tube, 3mm bore, ($45^{\circ}$-Wintrobe-ESR) was practiced for the blood of various levels of PCV under the ambient temperature of $10^{\circ}C$, $20^{\circ}C$ and $30^{\circ}C$. Correlation of the ESR to the ambient temperature showed linear regression each in five levels of PCV. The ESR increased with ascending ambient temperature, and magnitude of the increase of the ESR became greater as the level of PCV lowered. Correlation of the ESR to PCV showed curvilinear regression each in three levels of the ambient temperature, and the ESR was increased with decreasing PCV. The data were statistically analysed and a list of relative anticipated $45^{\circ}$-Wintrobe-ESR values for PCV and ambient temperature was presented.
