The possibility of using lysolecithin from rice bran oil (LL) in the diet of broiler chickens was explored. Lysolecithin was included in diet at graded levels (0, 0.05, 0.1, 0.2, 0.4, 0.8, 1.6 and 3.2 % in diet) and fed to a total of 640 broiler chickens from 0 to 35 d of age. The diets were isonitrogenous and isocaloric. Body weight was higher in the group fed the highest level (3.2 %) of LL. Feed intake was significantly (p<0.01) lower in the groups fed 1.6 and 3.2 % LL in comparison to control, whereas feed conversion efficiency was significantly (p<0.01) improved at the highest level of LL (3.2 %). Serum concentration of protein, total cholesterol and triglycerides as well as slaughter parameters, organ weights, fat deposition in liver and muscle, and SRBC response were not affected. The fat digestibility was significantly (p<0.05) improved at the higher levels (1.6 and 3.2 %) of LL in diet. It is concluded that rice bran oil LL could be safely used in broiler chicken diet and at dietary levels of > 1.6 % the LL improved the body weight, feed conversion efficiency and fat digestibility in broiler chickens.
