Changes in muscle and adipose tissue fatty acid composition
can be achieved by adding vitamin E and altering
dietary fatty acid content of the diet. Feeding high oil
corn- and high oil corn plus fat-based diets increased
the lipid oxidation in cooked pork but showed no effects
on fresh pork. Dietary vitamin E supplementation protected
pork from oxidation and altered fatty acid pro-
files of samples from the normal corn-based diet in both
the neutral and polar lipid fractions. The influence of
vitamin E supplementation of fatty acid proportions
was smaller for high oil corn- and high oil corn plus
fat-based diets. Therefore, these results are of importance
in providing consumers with a favorable meat
product and benefiting the pig industry. Establishing
the exact time, duration, and level of feeding requires
additional research efforts.
