1、黑龙江八一农垦大学硕士学位论文精粗比对绒山羊瘤胃发酵及营养物质流通规律影响的研究姓名:王立志申请学位级别:硕士专业:动物营养与饲料科学指导教师:姜宁20060501摘要选择18只健康的安装有永久性瘤胃瘘管和十二指肠近端瘘管的内蒙占白绒山羊羯羊,随机分为3组。分别饲喂精粗比为3:7、2:8和1:9的日粮,观察不同精粗比日粮对绒山羊瘤胃发酵及营养物质流通规律的影响。结果表明:不同精粗比且粮对绒山羊瘤冒oRP、NH3.N浓度没有显著影响(P>O.05)。l:9日粮显著提高了瘤胃DH值(P2、显著提高了瘤胃BcP含量(P3、er的含量(P<005)。根据M85+C15理想氨基酸平衡模式得出,3个处理组的(.ys、His和A曙相对于Lvs缺乏,2:8处理组缺乏程度最轻。3:7、2:8和1:9曰粮的氨基酸平衡指数分别为O.52、0.50和O.57。建议生产中妊娠期或生长期的绒山羊可采用精粗比3:7日粮,生绒期绒山羊可采用2:8日粮,非生绒期的成年绒山羊可采用1:9日粮。关键词:绒山羊,精粗比,瘤胃发酵,营养物质流通,消化代谢HAbstractEighteenmatureInnerMongoI{awhitecashmerewethergo4、atswere而nedwithpemlanentmminalandproximalduodenumnstulas,anddjV{dedintothreegroups.ThreeratiosOfdietaryconcentratet0mughagewere3:7,2:8a11d1:9,thenlmenfbmen诅tionandnutrientnowwerestudied.Theresultsshowed:Therewercnosj蛐i矗calltdi行brenceaboutrumenORPandNH{·Nconce5、ntrationindifre咖tdiets(P>O.05).111epHwaSincr。aSedsigIlificaIltIybyl:9mtio(P6、(P锄.O】),柚dtlleresultoft7、lethreetreatments仔omhighto10wwas3:7,2:8,l:9.The肿enefrectiVede孕强dabililyofdietNDFaIldADFfed3:7a11d2:8diettreatIllentswerehi曲ert11anl:9trealIIIent(P8、.05),血eme诅bolicrateandrete州。丌ofNfedJ:9dietwerehighestinthree仃eatments(P9、c15,thecontentofcys,His锄dAIgcomparedt0Lysweredeficient锄ongthree仃e咖en拓,锄dtllede历c即cyof2:8trea伽lentwasless.TheresultsaboutAminoAcidBalallceInd“f酣3:7,2:8柚dl:9dietwere0.52,0.50aIld0.57respec石
