To compare the effects of red Ginseng and white Ginseng on the growth of experimental animals, both Ginseng were given to Broiler male chicken. Red and white Ginseng were administered to Broiler chicken in doses of 0.25, 0.5, 1, 2 and 4g per kg weight of chicken. The increase in weight were 282g in red Ginseng group and 162g in white Ginseng group compared with control group. The increase of the feeding amounts per kg weight were 2.4kg for red Ginseng group, 2.67kg for white Ginseng group and 2.87kg for non-treated group. The growth of each organ in the red Ginseng group showed favorable increase trend than white Ginseng group as a whole and, particularly, considerable significance were observed in liver and brain. These results suggest that red Ginseng has better effect on the growth of chicken and organ than white Ginseng does.
