Abstract:

The effects of Ampelopsis grossedentata extract on growth performance, diarrhea rate and anti-oxidation function in mice were studied in this experiment. 90 mice were randomly divided into five groups: Blank group, experimental groups Ⅰ,Ⅱ,Ⅲ and control group. The mice in blank group were fed with basal diet, the experimental groups were added with 0.02, 0.04, 0.06 mg/(g·BW) of Ampelopsis grossedentata extract and the control group was added with colistin sulfate in basal diets, respectively. On the 26th day of the trial, the mice were administered folium senna and then record their diarrhea condition. The results showed that, the finial weights of mice in experimental and control groups were higher than that in blank group, and the difference between the blank and control groups were significant (P<0.05). Adding Ampelopsis grossedentata extract had a tendency to increase growth performance and liver weight, but the difference was not significant (P>0.05). The diarrhea rates in the control and experimental groups Ⅱ,Ⅲ were significantly lower than the blank and experimental group Ⅰ(P<0.05). Compared with the blank group, the activity of the serum glutathione peroxidase (GSH-Px) was significantly increased in control group (P<0.05), while the increasing trends were not significant in experimental groups (P>0.05). The activity of catalase (CAT) in control group was significantly higher than that in experimental group Ⅱ (P<0.05), and the serum superoxide dismutase (SOD) activities among the experimental groups were not significant (P>0.05). In conclusions, the growth performance and anti-oxidation function in mice could be increased, while the diarrhea rate could be decreased by adding the Ampelopsis grossedentata extract. It suggested that Ampelopsis grossedentata extract was expected to become a substitute for antibiotics in animal feeds.
