摘要
选用120只黑龙江籽鹅,随机分成3组(对照组和Ⅰ、Ⅱ两个试验组),每组40只。对照组饲喂基础日粮,试验Ⅰ、Ⅱ组在基础日粮中分别添加1.51、.0 ml/kg微生态制剂,试验期90 d。结果表明:试验Ⅰ、Ⅱ组盲肠中乳酸杆菌的菌群数量均高于对照组(P<0.05),大肠杆菌和沙门氏菌菌群数量均低于对照组(P<0.05);试验组之间差异不显著(P>0.05)。平均日耗料量和料肉比试验组与对照组相比差异显著(P<0.05)。表明微生态制剂能够调节籽鹅盲肠主要微生态菌群,提高机体免疫能力和生长性能。
120 Heilongjing Zi geese were divided into three groups（control and Ⅰ,Ⅱ groups）,every group was forty. The control group was base feed,The group Ⅰand Ⅱ were appended 1.5 ml/kg.1.0 ml/kg microecological products daily for 90 d in base feed. The result indicated： Compared with the control,the number of lactobacillus in the experimentsⅠ,Ⅱcaecum were all more significant（P〈0, 05）, the number of Enterobacillus and Salmonella were all much fewer （P〈0.05） tThe same experi mental group had no significiant difference （P〉0.05）. The experiments daily consuming feed and fresh propotion had signifi ciant difference compared with the control （P〈0.05）. The experiment showed that the microecological Pruducts had the func tion of regulating the important flora with impact on caecum, and increased the immune function and growth performance.
