This study was carried out to investigate the feeding effects of microcapsulated inulin (MI) from Jerusalem artichoke (Helianthus tuberosus L.) on blood lipid, fatty acid composition and cholesterol of egg in laying hens. Hyline brown layers of 25 weeks old were subjected to one of the following treatments for 4 weeks: a control group without MI, 800 ppm, 900 ppm, and 1,000 ppm. Compared with control group, levels of triacylglyceride and cholesterol in blood and egg cholesterol decreased significantly in groups MI groups. Egg saturated fatty acid was lower in MI groups than control group but not unsaturated fatty acid was significantly high in MI groups as compared to the group without MI. The results suggest that the addition of microcapsulated inulin to a laying hens' diet can improve egg quality by reducing blood lipids.
