Abstract:

To evaluate the possibility of subtituting in-feed antibiotics with fermented Chinese herb residues (CHR) as feed additive,120 three-way cross piglets weaned at 21 days of age were randomly assigned into 4 treatment groups with 6 replicatins with 5 piglets each replication,representing control group,CHR group,fermented CHR group and antibiotic (colistin sulfate) group.At the 28th day,1 pig was randomly selected from each replication,and the blood samples were collected from the anterior vena cava in the morning before feeding.The serum was isolated for testing the biochemical parameters,antioxidant and immunological indexes.The results showed that feed gain ratio (F/G) in fermented CHR group were significantly lower than that of the control and antibiotic groups (P < 0.05); Total protein and albumin of the fermented CHR group were significantly higher than that of the antibiotic group (P < 0.05); Triglyceride and total cholesterol of the fermented CHR group was significantly lower than that of the control group (P < 0.05); Glutathione contents,catalase and superoxide dimutase activities of fermented CHR group were significantly higher than that of the control group (P < 0.05); The contents of immunoglobulin G(IgG),IgA and IgM of CHR and fermented CHR groups were significantly higher than those of control and antibiotic groups (P < 0.05).These findings suggested that the fermented CHR could present certain roles in regulating plasma lipid concentration and improved the antioxidant capacity and immunity in weaned piglets,it could be used as the substitute for antibiotics in piglets' feed.
