Abstract: [Objective] To study the effects of basic ration with Emei hemsleya pellets additive on intestinal morphology and digestive enzyme activity of weaning piglets. [Method] Four groups divided from 96 weaning Duroc×Landrace×Yorkshire piglets with 7.86 kg (mean initial body weight)were fed 21 days by basic ration with different dosage of Emei hemsleya pellets additive. [Results] The results showed that 250 g/1 000 kg Emei hemsleya pellets additive could increase the length of duodenum, ileum, and duodenum villi significantly, and the ratio of length of bloom to the depth of pits, as well as amylase activity significantly. 500 g/1 000 kg Emei hemsleya pellets additive could improve intestinal morphology and digestive enzyme activity but the difference was not significant. [Conclusion] Adding appropriate amount of Emei hemsleya pellets can improve intestinal morphology and digestive enzyme activity of weaning piglets. Adding 250 g/1 000 kg Emei hemsleya pellets in basic ration can obtain the best intestinal morphology and digestive enzyme activity effect of weaning piglets.
