1、新疆农业大学硕士学位论文添喂延胡索酸二钠对绵羊消化代谢和血清生化指标的影响姓名:张彩芳申请学位级别:硕士专业:动物营养与饲料科学指导教师:杨开伦20090601添喂延胡索酸二钠对绵羊消化代谢和血清生化指标的影响摘要本论文研究了添加延胡索酸二钠对人工瘤胃产气量和干物质消失率的影响以及日粮中添喂延胡索酸二钠对绵羊消化代谢和血清生化指标的影响,旨在探讨延胡索酸二钠对绵羊消化代谢和生长的作用。试验I:在人工瘤胃发酵过程中,以19玉米秸秆,0.259淀粉为底物,分别添加延胡索酸二钠0,10,15,20ret001.L~,测定1,2,4,8,lO,12,16,2
2、0和24小时各时间点的产气量。结果表明,延胡索酸二钠各处理组的产气量均显著高于对照组(尸<0.05),各试验组的干物质消失率和累积产气量均显著高于对照组(尸.3、蛋白、纤维素和半纤维素的消化量均有极显著增加(尸<0.01);添加延胡索酸二钠209组绵羊干物质、有机物的消化率分别提高了7.18%(尸4、生化指标。试验结果表明,添加延胡索酸二钠组绵羊血清中的尿素氮、钙、磷、糖、甘油三酯、谷丙转氨酶等指标与对照组相比均无显著差异(尸>O.05)。本研究表明,延胡索酸二钠显著提高瘤胃体外培养的总产气量(P<0.05),提高了干物质降解率(PO.05)。关键词:延胡索酸二钠;绵羊;消化;代谢;血清生化指标EffectsofAdding5、sodiumfumaricacidtoDietonDigestion,MetabolismandSerumBiochemicalIndexesofSheepAbstractTheeffectsofsodiumfumaricacidwereconductedOninvitrogasproductionandDMdegradation.Theinfluenceofaddingfumaricacidtodietondigestion,metabolismandserumbiochemicalindexesofsheepwerefunherinvestiga6、tedtostudytheeffectsofaddingsodiumfumaricacidtodietondigestion,metabolismandgrowthofsheep.ExpermentI:GasproductionWasmeasuredat1,2,4,8,10,12,16,20,24hoveralltheinvitroincubationthatlgtomstrawand0.259starchwereaddedinruminalfermentation嬲substrateandadditivessodiumfumaricacid.sod7、iumfumaricacidsignificantlyincreasedtotalgasproductioninvitro(尸<0.05),enchanceinDMdegradationWasobservedwhensodiumfumaricacidWasused(P8、namerino(Xinjiangtype)sheepwereselectedandrandomlydivi
