Abstract: The liver is the largest digestive gland in poultry, and its growth and development are vital for playing functions. In the current study we observed the development of broiler liver tissue with the histological method, and compared the differences of the development of liver tissue between fat and lean lines during embryonic period. We found that the lobes of liver become bigger with developing, and the hepatic lobule structure was integrity when chicken embryo was 12-day-old. The hyperplastic and hypertrophic growth lipid droplets in liver cells significantly increased in the later stage of the embryogenesis, and the proliferation activity of liver cells located around was stronger than those which located in the center of the lobes of liver. During the whole embryonic period, there was no difference on the deposition of lipid droplets between the two lines.
