Vitamin E status of cattle and sheep 2: Survey of liver from clinically normal cattle and sheep for α-tocopherol

Abstract

Analysis of liver from clinically normal animals showed a mean α-tocopherol level of 20 mg/kg for cattle and 6 mg/kg for sheep. The corresponding normal values (mean ±2 S.D.) were 9 to 44 mg/kg and 1.8 to 20 mg/kg. The usefulness and assessment of tocopherol analyses on liver and serum samples are discussed in the light of these normal values and routine diagnostic submissions.
