Abstract

To evaluate the possibility of herbal residues used as feedstuff or feed additive, a total of 120 piglets weaned at 21 days of age were randomly assigned to four groups, representing control group, Qi-Zha oral solution residues (QOR) group, fermented QOR group and zinc oxide group, the effects of QOR and fermented QOR on growth performance, nutrient digestibility, intestinal mucosal morphology and tight junction protein mRNA relative expression of weaned piglets were determined. Each group contained five replicates and each replicate contained six weaned piglets. The experiment lasted for 28 days. The results showed as follows: 1) during the whole experiment stage (day 1 to 28), the ratio of fee to gain (F/G) of piglets in fermented QOR group was lower than that in control group and QOR group (P>0.05); the diarrhea rate of piglets in zinc oxide group was significantly lower than that in other groups (P<0.05). 2) At day 28 of the experiment, the digestibility of dry matter (DM), ether extract (EE) and crude protein (CP) of piglets in fermented QOR group was significantly lower than that in control group (P<0.05), the EE digestibility was significantly lower than that in QOR group (P<0.05), and the CP digestibility was significantly lower than that in zinc oxide group (P<0.05). 3) The villus height and villus height to crypt depth (V/C) value in jejunum and ileum of piglets in fermented QOR group were higher than those in QOR group (P>0.05), and the crypt depth and villus width were lower those that in QOR group (P>0.05). 4) There were no significant differences on the mRNA relative expression of Occludin and zonula occluden 1 in jejunum, ileum and colon among all groups (P>0.05). In conclusion, compared with the QOR, the fermented QOR can improve the intestinal morphology of weaned piglets in a certain extent, there is no significant effect on the mRNA relative expression of tight junction protein when dietary supplementation with fermented QOR and QOR.
