Abstract: To study the effects of cureumin on abdominal fat deposition, 120 one-day-old Huainan chickens were randomly, divided into two groups （group A and group B）with three duplicates in each group. The chickens of group A was the control kept with basal diet, and those in group B was fed with basal diet containing curcumin at the concentration of 350 mg/kg diet. The percentage of abdominal fat, subcutaneous fat thickness, and intramuscular fat width of the 28-day-old Huainan chickens respectively decreased by 3.91%, 4.13 %, and 52.01%, compared with these indexes of the control group. The content of serum cholesterol, low-density lipoprotein cholesterol, and triglycerides respectively decreased by 19.31%, 13.68 %, and 12.90 %, while that of high-density lipoprotein cholesterol and free fatty acids increased by 20.29 % and 12.28 %, respectively. The percentage of abdominal fat, subcutaneous fat thickness, and intramuscular fat width of the 42-day-old Huainan chickens respectively decreased by 34.48 %, 23.65 % and 27.35 %, compared with these indexes of the control group. The content of serum cholesterol, low-density lipoprotein cholesterol, and triglycerides respectively decreased by 23.22 %, 10.08 %, and 12.09 %, while that of high-density lipoprotein cholesterol and free fatty acids increased by 43.45 % and 13.58 %, respectively. The percentage of abdominal fat, subcutaneous fat thickness, and intramuscular fat width of the 56-day-old Huainan chickens respectively decreased by 63.67 %, 15.13 % and 42.33 %, compared with these indexes of the control group. The content of serum cholesterol and triglyeerides respectively decreased by 27.03 % and 37.33 %, while that of low-density lipoprotein cholesterol did not significantly decreased. The content of high-density lipoprotein cholesterol and free fatty acids increased by 68.31% and 24.71%, respectively.
