The objective of this trial was to investigate the effect of different ω-6/ω-3 PUFA ratios on blood lipid metabolism, and predictive factors for coronary artery disease in growing Yangzhou geese. Hundred and sixty 21-day-old healthy Yangzhou geese with average body weight of (0.407 0.023) kg were randomly divided into 4 groups. They were fed diets with different ω-6/ω-3 PUFA ratios, which were 3∶1, 6∶1, 9∶1 and 12∶1, respectively. The blood samples were obtained to determine the blood lipid, hypersensitive C-reactive protein (HsCRP), and soluble CD40 ligand (sCD40L) at the age of 42, 56, and 70 days, respectively. The results showed as follows: the geese fed the diet with the ω-6/ω-3 PUFA ratio of 6∶1 had much lower blood total triglyceride (TG) (P<0.05), total cholesterol (TC) (P<0.05), low-density lipoprotein (LDL) (P<0.05), and the highest high-density lipoprotein (HDL) (P<0.05) among the 4 groups at the age of 56 or 70 days. It was further observed that blood HsCRP or sCD40L levels were increased along with the ω-6/ω-3 PUFA ratio increasing, and generally were all the lowest in 3∶1 group, although no significant differences were found among the 4 groups (P>0.05). In conclusion, the diet with ω-6/ω-3 PUFA ratio of 6∶1 can decrease blood lipid; moreover, the diet with low ω-6/ω-3 PUFA ratios (3∶1) has a tendency to decrease blood HsCRP and sCD40L levels in Yangzhou geese.［Chinese Journal of Animal Nutrition, 2011, 23（8）：1289 -1295］
