【摘要】 本试验应用三种多株有益菌制成微生态制剂MX98替代抗生素，进行预防肉仔鸡腹泻促进增重试验，结果表明该制剂使肉仔鸡腹泻死亡率降低5％；1－7日龄时，试验组比对照组增重提高457％。8～14日龄时，提高1458o4％15～21日龄时，提高12．58％；使肉仔鸡成活率提高6％．更多还原

【Abstract】 MX98 microecologie preparation was used to instead of antibiotic toprevent broiler chickens from diarrhoea and to promote growth, which was consistedby three species of many strains beneficial bacteria. The result indicated thatit could reduce broiler chickens diarrhoea death rate by 5%’ chickens inexperimental group promoting growth 4. 75% more than those in control group during1 to 7 age, 14. 85% during & to 14 age, 12. 58% during 15 to 21 age; the survival ratewas raised by 6%.更多还原
