Effects of Compound Chinese Herbal Medicine on Production Performance and Intestinal Structure of Weaned Piglets

The effects of compound Chinese herbal medicine additive on the production performance and intestinal structure of weaned piglets were studied.The results showed that the test group IV had the best effect,and the test group II,III and IV could enhance the daily feed intake to a certain extent,and promote the growth speed of piglets.The intestinal villus length and intestinal recess depth of piglets in test group II,III and IV were significantly different from those of CK(P0.01),The villus height of duodenum and ileum in group IV,as well as the villus height of jejunum in group III were significantly bigger than those of group II(P0.05).As compared with CK,the ratio of the villus height to recess depth of piglets in test groups was increased,and there were significant differences in jejunum between group II and CK,and in duodenum and ileum between group III and CK(P 0.05).
