Effects of fermented traditional Chinese medicine on growth performance,blood biochemical indexes and immune function of finishing pigs
To investigate a series of effects of dietary fermented traditional Chinese medicine(Astragalus membranaceus,Radix Isatidis,Jujubae Fructus,Codonopsis Radix,Granati pericarpium,Forsythiae Fructus,and Scutellaria baicalensis)on clinical manifestations,production performance and blood biochemical parameters of finishing pigs,32 3-way(Dutch Large White)cross 100-day-old finishing pigs with body weight of(48±1)kg were selected as experimental animals and were randomly divided into four groups on average,including control group fed with a basal diet,low dose group fed with a basal diet supplemented 0.5%fermented traditional Chinese medicine,middle dose group fed with a basal diet supplemented 1%fermented traditional Chinese medicine and high dose group fed with a basal diet supplemented 2%fermented traditional Chinese medicine.The experiment lasted for 35 days,and during the test mental state,diarrhea,body temperature and productive performance of the subject pigs and ammonia in pig barn were monitored,the blood samples were obtained from pigs after the completion of the test and then used for tests of routine blood and serum biochemical indexes.The results showed that there were no apparent abnormalities in detection of mental status and body temperature of the pigs in experimental group after fermented traditional Chinese medicine treatment(P>0.05),while the fermented traditional Chinese medicine could restore the diarrhea of the pigs to a certain extent.The production performance of pigs in the experimental group was significantly improved,especially the average weight of pigs in the middle dose group increased 5.97 kg(26.49%)compared with that of pigs in the control group(P<0.01),the feed intake of the pigs was 11.90 kg(20.55%)higher(P<0.05)than control pigs,and the feed to meat ratio in the middle dose group was decreased 0.12(P<0.05).The results of ammonia monitoring showed that fermented Chinese herbs could significantly reduce the ammonia content 1.48 ppm(26.24%)in the middle group barn than that in control barn(P<0.01)after 28 day treatment.The results of blood routine examination showed that the number of white blood cells,lymphocytes,intermediate cells,granulocytes and platelets in the experimental group had no significant changes(P>0.05),while the number of red blood cells showed a slight increase in experimental groups(P>0.05)and hemoglobin content of pigs in low,middle and high dose group were elevated 20.49 g/L(17.22%),24.01 g/L(20.18%),25.48 g/L(21.41%)than those in the control group(P<0.01);The blood biochemical indexes showed that the contents of alanine transaminase,aspartate aminotransferase,alkaline phosphatase,creatinine,urea nitrogen and glucose in the experimental group had no significant changes(P>0.05),while the total protein and globulin contents were increased in a dose-dependent manner compared with the control group,and the effect of high dose was significantly enhanced 5.11 g/L(9.94%)and 5.56 g/L(17.14%)than that of control(P<0.05).Furthermore,ELISA test results showed that the contents of IgA,IgG and IgM in the experimental group were significantly increased(P<0.01),especially these in high dose group were elevated 248.50 mg/mL(38.37%),7.25 mg/mL(105.99%),146.29 mg/mL(24.68%)than that in control group(P<0.01).The preliminary study showed that feeding basal diet supplemented with fermented Chinese medicine had no obvious adverse effects on the pig body,and could improve the production performance of pigs,reduce the ammonia in the barn,and enhance the immune function of the body.
