2、B、c、D组,每组3个重复,每个重复8头,分别在基础日粮中添加0.08硫酸粘杆菌素、0.008穿心莲提取物以及0.025、0.05比例添加峨眉雪胆微丸进行21d饲养试验,以绒毛高度、隐窝深度、绒毛高度隐窝深度比值、消化酶活性等为考察指标,研究添加峨眉雪胆微丸对断奶仔猪肠道形态及消化酶活性的影响。【结果】结果表明,与添加抗生素对照组相比,0.025峨眉雪胆微丸添加组仔猪各段的绒毛高度,绒毛高度隐窝深度比值显著增加(P3、大(P<0.05),绒毛高度隐窝深度在十二指肠回肠部位显著增加(P<0.05),淀粉酶活性差异不显著(P>0.05),脂肪酶和胰蛋白酶活性降低。【结论】饲粮中添加适量的峨眉雪胆微丸可改善断奶仔猪肠道形态,并有提高消化酶活性的作用,其中以0.025峨眉雪胆微丸添加组的效果较好。关键词:峨眉雷胆微丸;断奶仔猪;肠道形态;消化酶活性中图分类号:$816.7;$853.72文献标志码:A文章编号:1000—2650(2015)02-0199-06EffectsofEmeihemsleyaPelletsAdditivesonIntes4、tinalMorphologyandDigestiveEnzymeActivityofWeaningPigletsMAShuang—kun,SENGXiao—lan,LIUYah—fang,LIYing—lun(CollegeofVeterinaryMedicine,SichuanAgriculturalUniversity,Wenjiang611130,Sichuan,China)Abstract:[ObjectivelTostudytheeffectsofbasicrationwithEmeihemsleyapellet5、sadditiveonintestinalmorphologyanddigestiveenzymeactivityofweaningpiglets.[MethodlFourgroupsdi—videdfrom96weaningDuroc×Landrace×Yorkshirepigletswith7.86kg(meaninitialbodyweight)werefed21daysbybasicrationwithdifferentdosageofEmeihemsleyapelletsadditive.[ResultslTher6、esultsshowedthat250g/1000kgEmeihemsleyapelletsadditivecouldincreasethelengthofduodenum,ileum,andduodenumvillisignificantly,andtheratiooflengthofbloomtothedepthofpits,aswellasamylaseactivitysignificantly.500g/1000kgEmeihemsleyapel—letsadditivecouldimproveintestina1m7、orphologyanddigestiveenzymeactivitybutthedifferencewasnotsignificant.[ConclusionlAddingappropriateamountofEmeihemsleyapelletscanim—proveintestinalmorphologyanddigestiveenzymeactivityofweaningpiglets.Adding250g/1000kgEmeihemsleyapelletsinbasicrationcanobtainthebesti8、ntestinalmorphologyanddigestiveenzymeactivityeffectofweaningpiglets.Keywords:Emeihemsl'eyapellets;weaningpiglet;intestina1morphology;digestiveenz
