Contributions to the study of blood constituents in domestic animals in South Africa. 1. Normal values for methaemoglobin reductase, erythrocyte fragility, blood glutathione, plasma catalase and the total erythrocyte pyridine nucleotides in sheep

Abstract

Blood analysis figures obtained from two groups of sheep of different geographical origin are presented. The one group emanated from the Karoo and the other from the Transvaal grassland. Substantial differences between groups for all factors excepting pyridine nucleotides are demonstrated. It is suggested that these differences may reflect basic disturbances in apparently healthy Karoo sheep connected with the aetiology of geeldikkop and enzootic icterus.
