Flaxseed fed pork: n−3 fatty acid enrichment and contribution to dietary recommendations

The potential to increase n−3 fatty acid (FA) intake via flaxseed fed pork is underestimated when restricted to pure longissimus muscle, whereas a combination of muscle and adipose tissue is typically consumed. Presently, the FA content of pigs fed 0%, 5% and 10% dietary flaxseed for 11weeks was measured in loin, picnic and butt primals (lean muscle with epimysium (L), L plus seam fat (LS), and LS plus 5mm backfat (LSS)). The n−3 FA content necessary for an enrichment claim in Canada (300mg/100g serving) was exceeded in L from all primals when feeding 5% flaxseed, being 4fold that of controls (P
