[The content of hemoglobin in the blood and the abundant and trace elements in blood plasma and erythrocytes of sheep, fallow deer, dwarf goats and reindeer].

Of the 4 species, the blood of fallow deer had the highest concentration of Hb (10.9 +/- 0.7) and that of pygmy goats (6.5 +/- 1.4 mmol/l) the lowest. The highest concentration of protein in the plasma was found in the reindeer (81.2 +/- 2.1) and the lowest in the pygmy goats (59.1 +/- 4.3 g/l). High values of ascorbic acid were recorded in the reindeer (16.4 +/- 2.4) and in the Finnish sheep (16.3 +/- 2.5 micrograms/ml). There existed some differences in the concentrations of Na, K, Ca, Mg, Pa, Fe, Cu and Zn in the plasma of the sheep of 7 different breeds under similar nutritional conditions. The erythrocytes of the sheep of 3 breeds and that of fallow deer, of pygmy goats and of reindeer uniformly had a low Na- and a high K-concentration. The Ca-concentration of the erythrocytes of the sheep of most breeds and that of the fallow deer and pygmy goats was very low, that of Mg and Zn was higher than in the plasma.
