Study of immune response in pigs fed with high vitamin E-dosages.
The effects of long-term vitamin E-supplementation on phagocytic cells, lymphocyte sub-populations, and SWC3+ cell count were studied in pigs. Eighteen weaned pigs were divided into three groups: 1) 100 mg DL-alpha tocopheryl acetate/kg diet, 2) 200 mg DL-alpha tocopheryl acetate/kg diet, 3) control group (basic feed with 10 mg DL-alpha tocopheryl acetate/kg diet). The examination of the immune indices was performed on day 120 of feeding the supplemented diets. The higher dietary levels of vitamin E resulted in increased serum concentration of alpha-tocopherol for both experimental groups (p < 0.05) and there were no significant differences in counts of CD2+, CD4+, CD8+, B lymphocytes nor SWC3+ cells among the groups. Similarly, vitamin E supplementation did not affect the functions of phagocytic cells tested.
