2、各半。根据评分标准分别记录休息过程中猪的精神状况。放血时收集血样,用于分析血浆中皮质醇、促肾上腺皮质激素(AcTH)浓度,乳酸脱氢酶、肌酸激酶活性,乳酸、血糖浓度;添加EDTA—K抗凝剂的血样用于血细胞分析。同时在放血时,测定血温。屠宰后,测定背最长肌24h滴水损失;背最长肌(LM)、半膜肌(SM)45rain以及24h的pH、色值、导电率。结果表明:①休息3h+玩具组在3个时间段的精神评分要极显著高于休g3h组,随着时间的延长猪都表现出趋于平静的趋势;②休息3h+玩具组和休息组3h组在皮质醇、促肾上腺皮质激素要显著低于不休组(P3、不休息组(Po.05)。根据上述的结果显示,宰前一定要让猪有一个休息的过程,这种措施能有效缓解猪的应激,并能恢复其免疫能力;在4、休息的过程中,添加部分福利玩具,至少对猪的精神状态有明显的好处。关键词:商品猪;休息方式;猪福利;血液指标;肉质中图分类号:$828.91;S811.8文献标识码:A文章编号:0366—6964(2009)11—1645—06TheInfluenceofLairageConditionsforFinishingPigsonMentalPerformance,BloodindexandMeatQualitycHAIJin,PENGJian,XIONGQi,ZHANGChang—xin。,MIA0Wen。,LIFeng—e,ZHENGRong。JIANGSi—wen01.Agric5、ulturalMinistryKeyLaboratoryOfSwineBreedingandGenetics&KeyLaboratory0fAgriculturalAnimalGenetics,Breeding,andReproductiono{MinistryotEducation,CollegeofAnimalScienceandTechnology,HuazhongAgriculturalUniversity,Wuhan430070,China;2.DepartmentofAnimalNutritionandFeedScience,CollegeofAnimalScien6、ceandTechnology,HuazhongAgriculturalUniversity,Wuhan430070,China;3.WuhanChinaporkCo.Ltd.,Wuhan430000,China)Abstract:Atotalof60crossbred(LargeWhite×Landrace)pigswithhalothanegenotypeNN(castratedmalesandfemales)wereallottedintothreetreatments:3hlairagewithtoys,3hlairageand0hlairageinarandomize7、dcompleteblockdesignandusedtoevaluatetheinfluenceoflairageconditionsonmentalperformance,bloodindexandmeatqualityforfinishingpigsatslaughter.Mentalperformanceofthepigswasrecordedbyscorestandardsduringlairage.Bloodsamplesweretakenatexsanguinationstom
