【摘要】：本試驗旨在研究約氏乳桿菌對大鼠生長性能、血液指標及臟器指數(shù)的影響。試驗選取SD大鼠80只,雌雄各半。大鼠按照體重相近的原則隨機分為4個劑量組,即陰性對照組、試驗Ⅰ(5 000 mg/kg體重)、試驗Ⅱ(1 000 mg/kg體重)和試驗Ⅲ組(200 mg/kg體重)。試驗期為30 d。結果表明:試驗劑量為200~1 000 mg/kg體重時,約氏乳桿菌對大鼠體增重、總采食量、飼料轉化率、血液學指標和病理學指標的影響無顯著性差異(P0.05);試驗劑量為5 000 mg/kg體重時,谷草轉氨酶、血糖、總膽固醇差異不顯著(P0.05);與其他劑量組相比,大鼠的體增重和總采食量顯著降低(P0.05),但飼料轉化率無顯著差異(P0.05);谷丙轉氨酶水平顯著降低(P0.05),白蛋白和總蛋白顯著增高(P0.05);雌性大鼠尿素氮和雄性大鼠肌酐顯著增高(P0.05)。綜合分析,約氏乳桿菌劑量低于1 000 mg/kg體重時,對大鼠平均日增重、血液指標及臟器指數(shù)無影響;約氏乳桿菌劑量高于5 000 mg/kg體重時,對大鼠臟器指數(shù)有影響。
