Abstract

The concentrations of tocopherols in blood serum, liver and adipose tissue of growing pigs with different vitamin E supply was estimated gas chromatographically. The animals were fed with a practical diet, supplemented with 0, 5, 15, 25 and 95 ppm dl α tocopheryl acetate (groups I-V). Based on a natural vitamin E content of 7.4 and 8.6 mg per kg of the diet, the control animals (group I) showed very low tocopherol concentrations of 0.5 μg per ml serum and about 1 μg per g tissue. No clinical vitamin E deficiency symptoms were observed. The increasing α tocopherol supplements raised the vitamin E contents in a proportional rate, and with high vitamin E supplies, the highest quantities of tocopherols were stored in the adipose tissue. When the α tocopherol content in the diet was raised by 1 mg, the concentration in the serum increased by 0.033 μg per ml, in the liver by 0.094 and in the adipose tissue by 0.129 μg per g, respectively (r=0.99). This increase in the concentrations was strongly linear and can be interpreted by constant rates of absorption and retention of α tocopherol in the present investigation. The growth of the pigs was not influenced by the different α tocopherol supplements.
