Abstract
- The experiment was to study the effect of natural plant extracts on growth performance, serum biochemical indexes, antioxidant capacity and immune function of weaning pigs. A total of 810 weaned piglets with an average body weight of 7 kg were randomly divided into three groups, with five replicates in each group and 54 piglets in each replicate. The piglets in blank group were fed with a basic diet, the piglets in control group were fed with basic diet supplemented with 53.2 mg/kg gritamycin + 39.2 mg/kg Bacillus peptide Zn, the piglets in test group were fed with basic diet supplemented with 500 g/t natural plant (dandelion and licorice, the content was 70%). The experiment lasted for 35 d, including 3 d of pre-experiment and 32 d of formal experiment. The results showed that adding natural plant extracts had a tendency to increase the weight of weaned piglets, ADG, ADFI and F/G (P>0.05). The diarrhea rate of piglets in test group and control group was significantly lower than that of blank group (P<0.05). ALB and HDL in serum of piglets in test group were significantly higher than that of blank group (P<0.05), TC and BUN were significantly lower than that of blank group (P<0.05). T-AOC and the activities of T-SOD and GSH-Px in serum of piglets of test group were significantly higher than those of control group and blank group (P<0.05), and the content of MDA was significantly lower than control group and blank group (P<0.05). The serum levels of IL-4 in test group and control group were significantly higher than blank group (P<0.05). The experiment indicates that natural plant extracts of dandelion and licorice can effectively reduce the diarrhea rate of weaned piglets, enhance the piglet's immunity and antioxidant capacity, improve growth performance.
