AbstractIndividual blood samples showed variation in components between range cows and for the same animal at different seasons. Adjusted means values for all blood samples were: phosphorus and calcium per 100 ml plasma 5.2 and 11.4 mg, respectively; hemoglobin 11.6 gm per 100 ml blood; and hematocrit 54% packed cells. Blood calcium, hemoglobin, and hematocrit levels were significantly influenced by season and breed of cow. There was a highly significant season effect on blood phosphorus, a significant breed x season interaction, and a non-significant effect when values were averaged for all seasons.
