Chickens were randomly divided into 9 treatments (32 for each treatment, 8 for each replicate). A 33 (chromiumbetaine) experiment with replicates was designed. The basal diet was used as control group, and the experiment lasted for four weeks. (Result) The result showed 1) there were significant effects of interaction between betaine and chromium on slaughter rate, abdomininal fat rate, the rate of the whole pure thorax (P0.05); 2) Betaine and chromium on the content of cholesterol (TC) and triglycerides (TG) in liver and muscle of chest and leg had interactive effects (P0.01). Analysis showed that, it was better for the test group to add 1 000 g/kg betaine and 400 g/kg chromium at the sane time; 3) At the end of 7 weeks, betaine and chromium significantly increased the concentrations of serum total protein (TP), albumin (ALB), free fatty acid (FFA), high density lipid protein cholesterol (HDL-C) in serum compared with control group (P0.01) and significantly reduced the concentrations of cholesterol (TC), uric acid (UA), low density lipid protein cholesterol (LDL-C), triglycerides (TG), and glucose (Glu).
