摘　　要：文章旨在探究茯苓多糖(Pachymaran,PM)对哺乳期羔羊生长性能、血清生化指标和抗氧化指标的影响。试验将80只10日龄湖羊羔羊随机分为4组,每组5个重复,每个重复4只,各组日粮分别在基础开食料中添加0、40、80和160 mg/kg的PM,试验为期52 d。结果显示:与对照组相比,80和160 mg/kg的PM组羔羊末重分别显著上调5.66%和7.82%(P<0.05);160 mg/kg的PM组羔羊日增重显著上调10.14%(P<0.05);80和160 mg/kg的PM组羔羊料肉比分别显著下降5.62%和8.23%(P<0.05),此外,未观察到PM对羔羊采食量的显著影响(P>0.05)。160 mg/kg的PM组羔羊血清总蛋白(TP)含量显著上升(P<0.05),80和160 mg/kg的PM组羔羊血清白蛋白(Alb)、葡萄糖(GLU)及生长激素(GH)含量显著上升(P<0.05),80和160 mg/kg的PM组羔羊血清尿素氮(BUN)含量显著下降(P<0.05)。160 mg/kg的PM组羔羊血清总抗氧化力(T-AOC)能力、还原型谷胱甘肽(GSH)含量显著上升(P<0.05),氧化型谷胱甘肽(GSSG)含量显著下降(P<0.05),80和160 mg/kg的PM组羔羊血清丙二醛(MDA)含量显著下降(P<0.05),谷胱甘肽过氧化物酶(GSH-Px)活性显著升高(P<0.05)。结论:补充PM(160 mg/kg)可通过提高羔羊代谢效率及抗氧化能力促进其生长发育。Explore the effects of Pachymaran(PM)on the growth performance,serum biochemical indicators,and antioxidant indicators of lactating lambs.8010 day old lake lambs were randomly divided into 4 groups,with 5 replicates in each group and 4 lambs per replicate.They were fed with experimental feed supplemented with 0,40,80,and 160 mg/kg PM in the basic feed for a total of 52 days.The results showed that compared with the control group,the PM groups at 80 and 160 mg/kg effectively increased the final weight of lambs by 5.66%and 7.82%,respectively(P<0.05);The daily weight gain of lambs in the PM group at 160 mg/kg was effectively upregulated by 10.14%(P<0.05);The feed to meat ratio decreased by 5.62%and 8.23%respectively(P<0.05),and no effective effect of PM on lamb feed intake was observed(P>0.05).The serum TP content of lambs in the 160 mg/kg PM group significantly increased(P<0.05),while the serum ALB,GLU,and GH content of lambs in the 80 and 160 mg/kg PM groups significantly increased(P<0.05).The serum BUN content of lambs in the 80 and 160 mg/kg PM groups significantly decreased(P<0.05).The T-AOC ability and GSH content in the serum of lambs in the 160 mg/kg PM group significantly increased(P<0.05),while the GSSG content significantly decreased(P<0.05).The MDA content in the serum of lambs in the 80 and 160 mg/kg PM groups significantly decreased(P<0.05),and the GSH Px activity significantly increased(P<0.05).Conclusion:Supplementing with PM(160 mg/kg)promotes the growth and development of lambs by enhancing their metabolic efficiency and antioxidant capacity.
