However, in weanling piglets the activity of lactase was decreased by 41.40%(P<0.05),whereas the activity of maltase increased by 22.31%(P<0.01) in jejunum, the activity of maltase increased by 21.14%(P<0.05)in colon. This result indicates that feeding daidzein can improve the using of disaccharide in piglets.展开更多
