The present study has shown what amount of mackerel oil should be added to hog in order to produce pork rich in DHA. The addition of 5% of mackerel oil to feed increased DHA contents in a hog sirloin significantly compared to control. With 1%, 2% or 5% added mackerel oil added to feed, DHA content in a hog sirloin tended to increase as the addition rate, however, the increase was not significant. Further, there was examined if the addition of antioxidants (tea leaves, vitamin E or herbs) to mackerel oil could be effective. In each group the DHA contents in a hog sirloin were increased significantly. Compared to the addition of l% of mackerel oil only, the combined use of the antioxidants with mackerel oil increases DHA content, however, the increase was not significant. Next, the effect of additional mackerel oil, which should be powdered and mixed with finely divided silicon dioxide, was examined, and found increase in DHA content in hog sirloin, and the increase was significant. In addition, the powdered mackerel oil was tractable.
