Synthetic vitamin E (all-rac-alpha-Tocoferol) is the most common source for livestock feed, but recent studies demonstrated that the relative bioactivity of natural vitamin E (RRR-alpha-Tocoferol) is 1.3 - 2.6 times higher than the synthetic form in pigs. This experiment evaluated the natural vitami...
