Fatty acid composition of commercially manufactured omega-3 enriched pork products, haddock, and mackerel.

This study was conducted to determine the commercial feasibility of feeding a 15% ground flaxseed diet to finishing hogs for up to 42 d before slaughter and to compare the fatty acid composition of the resulting pork products with commercially produced haddock and mackerel. Eighty-seven pigs were fed a control diet (predominantly corn, soybean meal-based) and then a similar diet containing 15% flaxseed for the last 28 (FS28) or 42 d (FS42) before slaughter. Control pigs were continued on the control diet (CO28 and CO42).
