Radioisotopic studies on equine infections anemia. II. Red cell mass and blood volume of thoroughbred horses determined with 51chromium

Abstract

Red cell mass and blood volume of 16 Thoroughbred horses, 11 healthy and 5 with naturally acquired Equine lnfectious Anemia, were determined by means of  ⁵¹Cr-tagged erythrocytes. The mean values obtained in healthy Thoroughbred horses were as follows:  red cell mass 40,64 and blood volume 102,32 ml/kg body weight. The mean red cell mass and blood volume in anemic horses were respectively 21,13 and 107,71 ml/kg body weight. The difference in the red cell mass values between the two groups was statistically significant (P < 0,01). There was significant correlation between erythrocyte mass and body weight (r = 0,89) in healthy horses.
