【摘要】 选用1日龄 AA 肉仔鸡,在基础日粮中添加0.1%和0.2%的宝肠安,以基础日粮为对照,进行为期7周的饲喂试验,分阶段统计增重、耗料,并对粪便中的微生物计数。结果:试验组肉仔鸡的末期平均体重、净增重和日增重均高于对照组,差异显著,但均比抗生素组低,差异不显著。试验组肉仔鸡的平均耗料量均略高于对照组,试验组的饲料利用率较对照组提高3.14%,比抗生素组低。试验组肉仔鸡粪便中双歧杆菌的数量远高于对照组,但大肠杆菌的数量却明显低于对照组。经济效益分析,试验组分别比对照组减少净增重耗料成本0.308元/kg、0.397元/kg,相对经济效益提高了 6.38%、8.38%。结果表明,宝肠安能显著提高 AA 肉仔鸡的生产性能,提高饲料转化率,并能促进双歧杆菌等厌氧菌的增殖,抑制大肠杆菌等致病菌的生长,取得较好的经济效益。更多还原

【Abstract】 Choose 1 day-old AA broilers in the diets added 0.1% and 0.2% of BaoChangAn.basal diet as a control for a period of seven weeks of feeding experiments,phased statistical Increase the weight,feed consumption,as well as stool microbial count.Results:The unit of the average broiler weight,net weight and daily gain all higher,Notable differences.But lower than in the antibiotic group,the difference was not Notable differences.Broilers group average volume slightly higher feed Consumption,Test group of feed utilization compared with the control group increased 3.14%,lower than the antibiotics.Test group of Broilers Bifidobacterium number of Excreta far higher,but the number of E.coil significantly lower than the control group.Economic analysis,the experimental group than the control group reduced net weight Consumption cost $0.308 kilogram,$0.397 kilogram,a relatively higher economic efficiency 6.38%,8.38%.The results showed that BaoChangAn can significantly enhance the AA broiler production performance and improve feed conversion rates,and promote anaerobic bacteria such as Bifidobacteria proliferation,Inhibition orE.coli and other pathogenic bacteria growth,achieve better economic efficiency.更多还原
