Study On The Effects Of Chinese Herbal Medicine On Production Performance Of Nursing Sow

In order to study the effects of Chinese herbal medicine on production performance, nutrient metabolism, gut microbes and serum biochemical indexes of nursing sow, three experiments were included in this study.Experiment 1: Twenty-five nursing sows were randomly assigned to five groups, 5 duplicates in each group, 1 nursing sow in each duplicate. Five groups received the same basal diet. The group of low-dose, mid-does and high-dose was added with 0.25%, 0.50 % and 0.75% Chinese herbal medicine, respectively; and the microbial group was added with 0.1% probiotics in the diets. Experimental period was 28 days. The feeding results showed that body weights of litters in the low-dose group were increased by 19.66kg (P<0.05), compared with the control. The daily weight gain and litter size in the low-dose group at weaning were increased by 6.16% and 14.34% (P>0.05), respectively. The results indicated that the Chinese herbal medicine could improve the production performance of nursing sow.Experiment 2: At the end of the test, the nutrient digestibilities of different groups were studied. The results showed that the different doses of Chinese herbal medicine significantly improve nutrient digestibility of the nursing sow. Compared with control group, the digestibilities of CP, EE, Ca and P were increased by 16.69%, 12.78%, 15.86% and 12.13% (P<0.05), respectively.Experiment 3: Common microbiological test was used to determine gut microbes. The results showed that the different doses of the Chinese herbal medicine could affect gut microbes. Compared with control, the number of E.coli in the group of low-dose and mid-dose was decreased by 46.15% and 64.96% (P<0.05), and the number of Lactobacillus in the group of low-dose was increased by 75.18% (P<0.05). The serum biochemical analyses showed that the contents of TP and GLO were increased by 21.53% and 36.30%, respectively; the T-BLL was decreased by 71.11%(P<0.05). The results indicated that the Chinese herbal medicine could promote beneficial bacteria, inhibit E.coli growth, and improve body immunity. In conclusion, the Chinese herbal medicine in nursing sow diets could significantly increase production performance and the nutrient digestibility, promote beneficial bacteria and inhibit E.coli growth, and improve body immunity.
