不同剂型蓝桉精油对保育猪生长性能、血清生化和抗氧化指标的影响
Effects of Different Formulations of Eucalyptus globulus Essential Oil on Growth Performance,Serum Biochemical and Antioxidant Indexes in Weaned Pigs
摘要
Abstract
This experiment was conducted to investigate the effects of different forms of Eucalyptus globulus essential oil(EEO)on the growth performance,serum biochemistry,and antioxidant indexes of weaned pigs.A total of 360 healthy"Duroc×Landrace×Yorkshire"nursery pigs with an average age of 57 d and an aver-age body weight of 20.38 kg were selected.They were randomly divided into three groups,with four repli-cates per group and 30 pigs per replicate.The con-trol group was fed a basal diet,while the regular form group and the coated form group were supple-mented with 200 mg/kg of regular form and coated form EEO,respectively,in the basal diet.The experimental period lasted for 28 d.The results showed that:① dietary supplementation with coated form EEO significantly increased the final body weight,average daily gain(ADG),and aver-age daily feed intake(ADFI)of nursery pigs(P<0.05),and decreased the feed-to-gain ratio(F/G)(P<0.05).However,regular form EEO had no sig-nificant effects on the growth performance of nursery pigs(P>0.05).② Dietary supplementation of coated form EEO significantly increased the serum contents of immunoglobulin A(IgA)and immunoglobulin M(IgM)in nursery pigs(P<0.05).In contrast,regular form EEO had no significant effects on the serum levels of IgA and IgM in nursery pigs(P>0.05).Additionally,neither regular form nor coated form EEO had signifi-cant effects on the serum contents of total protein(TP),albumin(ALB),urea nitrogen(UN)and immuno-globulin G(IgG)(P>0.05).③ Dietary supplementation of both regular form and coated form EEO had no sig-nificant effects on the serum total antioxidant capacity(T-AOC),glutathione peroxidase(GSH-Px)and superoxide dismutase(SOD)activity,or malondialdehyde(MDA)levels(P>0.05).In conclusion,dietary supplementation of 200 mg/kg coated EEO effectively improved the immune function and growth perfor-mance in nursery pigs.关键词
