Blood Components of Range Cattle: Phosphorus, Calcium, Hemoglobin, and Hematocrit

Individual 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.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
