【摘要】：本試驗(yàn)旨在研究約氏乳桿菌對(duì)大鼠生長(zhǎng)性能、血液指標(biāo)及臟器指數(shù)的影響。試驗(yàn)選取SD大鼠80只,雌雄各半。大鼠按照體重相近的原則隨機(jī)分為4個(gè)劑量組,即陰性對(duì)照組、試驗(yàn)Ⅰ(5 000 mg/kg體重)、試驗(yàn)Ⅱ(1 000 mg/kg體重)和試驗(yàn)Ⅲ組(200 mg/kg體重)。試驗(yàn)期為30 d。結(jié)果表明:試驗(yàn)劑量為200~1 000 mg/kg體重時(shí),約氏乳桿菌對(duì)大鼠體增重、總采食量、飼料轉(zhuǎn)化率、血液學(xué)指標(biāo)和病理學(xué)指標(biāo)的影響無(wú)顯著性差異(P0.05);試驗(yàn)劑量為5 000 mg/kg體重時(shí),谷草轉(zhuǎn)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(zhuǎn)化率無(wú)顯著差異(P0.05);谷丙轉(zhuǎn)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(shí),對(duì)大鼠平均日增重、血液指標(biāo)及臟器指數(shù)無(wú)影響;約氏乳桿菌劑量高于5 000 mg/kg體重時(shí),對(duì)大鼠臟器指數(shù)有影響。
[Abstract]:The purpose of this study was to study the effects of Lactobacillus yoelii on growth performance, blood index and viscera index in rats. 80 SD rats, half male and half female, were selected. Rats were randomly divided into four groups according to the principle of similar body weight: negative control group, test 鈪，
