Blood reference values in the lamb (Na, K, Ca, P, Mg, Cu, Zn, Cl, urea, total proteins, creatinine, uric acid, alkaline phosphatase, aspartate amino transferase, cholesterol and hemoglobin).

We have determined sixteen blood chemical parameters in three month-old lambs and eleven in one and a half-month old ones. We have found that three of them were not affected by age: potassium, copper and proteins; seven were lowered: sodium, calcium, zinc, chlorine, inorganic phosphate, urea and cholesterol; one was enhanced : magnesium. These reference values will be used as a basis for further controls of the flocks.
