1. 1. Spectrophotometric assays of twelve different enzymes of red blood cells were conducted in six breeds of cattle. 2. 2. Activity of fructose diphosphate aldolase was significantly higher in Sahiwal and crossbred [( Bos indicus) Sahiwal x ( Bos taurus) Red Polls] than in the other breeds. 3. 3. The rates of regeneration of reduced glutathione (GSH) and the activity of the enzymes associated with the regeneration of GSH (hexokinase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase and glutathione reductase) were not significantly different between the breeds studied.
