Radioisotopic studies on equine infectious anemia, 2

Red cell mass and blood volume of 16 thoroughbred horse, 11 healthy and 5 with naturally acquired equine infectious 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 red cell mass value 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
