ABSTRACT
This study evaluated the effects of sorghum in corn substitution and tanic acid added tocorn-soybean based diets on plasma cholesterol levels and triglyceride levels in lipoprotein fractions andtotal plasma in broilers. Lipoproteins of very low density lipoprotein (VLDL), low density (LDL) andhigh density(HDL) of the plasma were separated by ultracentrifugation using density gradient at 25.000 rpm for 20hours and 8ºC. Lipoproteins were collected and cholesterol and triglycerides were determined in eachfraction. Not observed significant differences between treatments. Therefore, the substitution of corn bysorghum and the addition of tanic acid to corn-soybean based diets given to broilers did not changesignificantly cholesterol and triglyceride levels in lipoprotein fractions and in total plasma.
