| 摘 要： | 选择断奶1～10d杜长大三元杂交仔猪90头,按随机区组设计分为3组,A组(麦科隆预防试验组)、B组(麦科隆治疗试验组)、C组(青霉素治疗对照组)各30头。通过20d试验,在用致病性大肠杆菌攻毒后,A组发病率为20.00%,比未进行保护的B,C两组的66.67%,70.00%分别下降了46.67和50.00个百分点,差异极显著(P<0.01)。治愈率A组为100%,比B,C两组的91.13%和90.05%分别提高8.87和9.95个百分点,差异显著(P<0.05)。B,C两组比较,差异显著(P<0.05)。死淘率A组为0,B,C两组分别为4.67%和10.53%,A组与B,C两组比较,差异极显著(P<0.01)。B,C两组相比,差异显著(P<0.05)。说明麦科隆微生物制剂对大肠杆菌具有良好的预防和治疗作用,是抗生素的有效替代品。

| Abstract: | 90 ternary hybrid Duchangda piglets were selected and randomly divided into three 30-piglet groups.Group A of Maikelong prevention group B Maikelong cure and group C penicillin cure control group.In 20 days of pathogenic E.coli agression,group A showed an infection rate of 20.00%,which was 46.67% and 50.00% lower than 66.07% and 70.00% of group B and C (P<0.01).There is a significant difference between group B and C.The death culling rale for group A was zero while 4.67% and 10.53% for group B and C.There is a significant difference between group A and group B and C (P<0.01).While the difference between group B and C was also significant (P<0.05).The results suggest that Maikelong micrbial agent has a good prevention and cure effect to E.coli and it is an effective alternative to antibiotic. |
