| Abstracts Objectives: The purpose of this research was to determine the effects of turmeric powder in diets based on soybean oil, on antioxidant status, blood enzyme and lipid metabolism of broiler chicks. Methodology: Two hundred sixty-four one-day old broilers were randomly assigned to 3 dietary treatments containing 0, 0.4 and 0.8% turmeric powder (TP). Each dietary treatment was replicated 4 times with 22 broilers each. Feed and fresh water were supplied ad libitum. The daily temperature was increased from 21 to 32oC for 5 hours at 28 to 42 days of age. At the end of experiment blood samples for plasma and hemolysate were taken. The concentration of blood lipids in serum was determined. The activity of some enzyme including Aspartate Transaminase (AST), Alanine Transaminase (ALT), Alkaline Phosphatase (ALP), and Creatine kinase (CK), Glutathione peroxidase (GPx) and superoxide dismutase (SOD) were estimated. Data were subjected to the analysis of variance using the General Linear Model of SAS. Results: The Triglyceride, LDL were not affected by the level of turmeric powder (TP) in dietary treatments. Serum cholesterol decreased when birds fed 4 g/Kg TP, but the HDL increased. The activity of ALP decreased in birds fed TP; however the activity of ALT and AST did not affected. Turmeric powder decreased the tiobarbituric acid reaction score (TBARS). The activity of GPx and SOD enzyme increased when birds fed turmeric powder. Conclusion: Supplementation of turmeric powder to diets based soybean oil could improve antioxidant status (GPx, SOD, and TBARS) and decreased activity of ALP of broilers fed diets contained TP. Key words: Tturmeric powder, soybean oil, lipid metabolism, enzyme activity, broiler. | ||
