Abstract: Twenty one Holstein Friesian and Brown Swiss female calves, at 6-12 months of ages were used in this study. They were kept in open-shed barn at –10?C ambient temperature and 50 % relative humidity conditions during December. Then, in January the animals were kept in stall barn at 15?C ambient temperature and 75 % relative humidity. In each barn, blood samples were taken from the animals on three consecutive days at the end of both December and January and analyzed for serum sodium, potassium, PCV %, hemoglobin and erythrocyte values. Except for erythrocyte counts, all blood parameters are affected by types of barn, however breed factor was found significant for only erythrocyte count. Serum potassium levels were changed by the age of animals. Some interactions between factors were found to be significant.
