216 one-day-old Wanjiang Yellow Chickens(male) were divided into four treatment groups by weight to study the effect of curcumin on metabolism of fat in Wanjiang Yellow Chickens.Every group included three replicates of 18 birds each,which received the same basal diet supplemented with 0,150,250 and 350 mg/kg curcumin respectively during the period 1 to 42 d post-hatching.The results showed that the percentage of abdominal fat weight and percentage of liver fat weight were significantly decreased by supplementation of 250 mg/kg or 350 mg/kg curcumin(P0.05).Subcutaneous fat thickness and inter-muscular fat width were significantly decreased by supplementation of 350 mg/kg curcumin(P0.05).When adding 250 mg/kg or 350 mg/kg curcumin,the total cholesterol(TC) concentration and the content of triglyceride(TG) in serum obviously reduced(P0.05),high density lipoprotein(HDL) level and free fatty acid(FFA) concentration in serum increased(P0.05),so the activity of hormone sensitive lipase(HSL) was enhanced(P0.05),but the activity of malate dehydrogenase(MDH) in abdominal fat decreased(P0.05).When adding 350 mg/kg curcumin,the low density lipoprotein(VLDL) level in serum obviously reduced(P0.05).The results implied that the curcumin could reduce the fat deposition by regulating the enzymes activities related to fat metabolism and by adjusting blood lipid metabolism.
