Effects of dietary taurine on the abdominal fat weight and serum and liver concentrations of cholesterol were investigated with male broiler chicks. One-day old chicks were allocated to one of three taurine supplemented diets: 0 (control), 1 and 2%. Body weight gain of chicks fed the diet supplemented with 2% taurine decreased by 6% compared to the control (P$prec$0.05). However, feed conversion ratio was not different among treatments. Liver weight and ratio of liver weight to body weight showed no difference among treatments. Abdominal fat weights were lower in 1% and 2% taurine supplementations by 14% and 20%, respectively, than that of the control (P$prec$0.05). Serum concentrations of triglyceride, glucose, glutamic oxaloacetic transaminase and glutamic pyruvic transaminase were not different among treatments. However, serum concentrations of total cholesterol were higher in 1% and 2% taurine supplementations by 10% and 12%, respectively, than that of the control (P$prec$0.05). Also serum concentrations of HDL-cholesterol increased in 1% and 2% taurine supplementations by 20% and 34%, respectively, compared to the control (P$prec$0.05). Concentrations of total cholesterol in liver decreased in 1% and 2% taurine supplementation by 9% and 13%, compared to the control (P$prec$0.05). Also concentrations of HDL-cholesterol in liver were lower in 1.0% and 2.0% taurine supplementation by 20% and 38%, respectively, than that of the control (P$prec$0.05). These results showed that taurine supplementation decreased the fat storage in abdominal cavity and affected on the cholesterol metabolism in liver of broiler chicks.
