摘要 本试验旨在探讨多糖对早期断奶仔猪部分免疫性能的影响。试验选用21日龄健康杜×长×大断奶仔猪(5.30±0.25kg)25头,随机分为5个组,每组5头。分别饲喂饲喂玉米-豆粕型基础日粮,基础日粮+0.3%白术纯多糖(PPAM);基础日粮+0.6%复合粗多糖(CCP);基础日粮+0.6%白术粗多糖(CPAM);基础日粮+抗生素(15%金霉素150mg/kg+4%黄霉素50mg/kg)(ANT)。试验期为14天。结果表明:PPAM能显著提高早期断奶仔猪血清中IgG和IgM的浓度(P<0.05)。ANT组和PPAM均能促进红细胞数量增加(P<0.05)。PPAM组脾脏指数呈极显著高于CR组(P<0.01),也显著高于CCP组和ANT组(P<0.05)。CCP和CPAM组胸腺指数则极显著高于CR组(P<0.01)。PPAM,ANT组胸腺指数显著高于CR组(P<0.05)。结论:,饲料中添加PPAM效果较好。 To study the effects of polysaccharides on some immune indices of early-weaned piglets.Twenty-five "Duroc x LandracexYorkshire"crossbred weaned piglets (21day,5.3±0.25kg BW)were randomly divided into 5 groups of 5 replicates per treatment and one piglet per replicate,fed with basal diet,basal diet plus 0.3% pure polysaccharides of Atractylodes macrocephala koid (PPAM),0.6%crude compound polysaccharides (CCP)or 0.6%polysaccharides of Atractylodes macrocephala koidz(CPAM) ,or adding antibiotic(15% chlortetracycline 150mg/kg and 4% flavomycin 50mg/kg)(ANT).The trial lasted for 14 days.The results showed as follows:the concentrations of IgG and IgM in serum of PPAM were significantly increased (P〈0.05), Red blood cell numbers were higher significantly after feeding PPAM and ANT (P〈0.05). The index of spleen of PPAM and CPAM were higher than that of CR (P〈0.01 ;P〈0.05 respectively).The index of spleen of PPAM were enhanced significantly compared with CCP and ANT respectively (P〈0.05);the index of thymus of CCP and CPAM were greatly higher significantly (P〈0.01),while the index of thymus of PPAM and ANT were improved (P〈0.05).In a word,dietary supplementation of PPAM were best in our experiment.
