Abstract Background The status of a-tocopherol vit E and selenium Se has been shown to influence disease resistance in pigs and may be important for the health of weanling pigs. Methods Plasma levels of both vit E and Se were followed in weanling pigs under field conditions in six Norwegian pig herds. Plasma vit E and Se were measured in 3 sows from each herd and 4 piglets in the litter of each sow at the day before weaning day -1 and in the same piglets at days 4 8 and 18 after weaning. Results Mean plasma vit E was pg ml in the sows and pg ml in the piglets at day -1 fell to pg ml in the weanling pigs at day 4 and remained low. Mean plasma Se was pg g in the sows and pg g in the piglets at day -1 rose to pg g in the .
