Effects of dietary canola seed and soy lecithin in high-forage diets on cholesterol content and fatty acid composition of carcass tissues of growing ram lambs

The influence of unsaturated fatty acids and phospholipids in high-forage diet on total lipid content, cholesterol content, and fatty acid composition in 43 lamb carcasses was determined by assigning the lambs into 4 groups with varied dietary treatments: control, with canola seed (CS), with soy lecithin(SL), and with both conala seed and soy lecithin(CSSL). Lean tissue analysis by gas-liquid chromatography revealed CS fed lambs had reduced total polyunsturated fatty acids (PUFA) while an increase was noted with the SL fed group. With adipose tissue, CS fed lambs showed lower saturated fatty acids and SL group, increasedPUFA. The effects of CSSL feeding was not significant.
