Effects of Gynostemma Pentaphyllum Extract on Growth Performance,Serum Indexes and Meat Quality of Finishing Pigs
This experiment aimed to investigate the effects of Gynostemma pentaphyllum extract on growth performance,serum biochemical indexes,immune function,antioxidant performance,and meat quality in finishing pigs.Thirty-six"Duroc×Large White× Landrace"finishing pigs around 120 days of age,in good health and with similar body weights 50.26±0.86kg,were randomly divided into the control group,the test group Ⅰ(Group Ⅰ),and the test group Ⅱ(Group Ⅱ),with 12 pigs in each group(half male and half fe-male).In the pre-feeding period of 7 d,the basal diet was fed,and in the formal experimental period of 60 d,the control group was fed the basal diet,while groups Ⅰ and Ⅱ were supplemented with 200 mg/kg and 400 mg/kg of G.pentaphyllum extract in the basal diet,respectively.The results showed that there was no significant difference in ADG,ADFI and F/G between groups with different levels of G.pentaphyllum extract(P＞0.05).On the 30th d of the test,compared with the control group,the serum aspartate amin-otransferase(AST)content was significantly lower in group Ⅱ(P＜0.05),serum immunoglobulin A(IgA),immunoglobulin G(IgG)levels and catalase(CAT)activity were significantly higher in group Ⅰ(P＜0.05),and immunoglobulin M(IgM)level in group Ⅱ were significantly higher(P＜0.05).On the 60th d of the test,compared with the control group,serum creatinine(CREA),alanine aminotransferase(ALT),and AST concentrations were significantly lower in Group Ⅰ(P＜0.05),serum high-density lipo-protein(HDL-C)content and CAT activity were significantly higher in Group Ⅰ(P＜0.05),serum malon-dialdehyde(MDA)concentration were significantly lower in both Group Ⅰ and Group Ⅱ(P＜0.05),and dorsal longest muscle pH24 h,brightness(L*),redness(a*)and yellowness(b*)values were signifi-cantly higher in the group Ⅰ than those of the control group(P＜0.05).In conclusion,after using appropri-ate amounts of G.pentaphyllum extract in finishing pig farming,some serum biochemical parameters were improved,humoral immune functions were enhanced,antioxidant properties were increased,and meat quality was improved.Under the conditions of this experiment,it is recommended that the appropri-ate level of G.pentaphyllum extract in finishing pig diets should be 200 mg/kg.
