摘要
为研究梭立康对犊牛产气荚膜梭菌病中的预防效果,将16头30~60日龄的新生黑白花犊牛随机分成试验组(11头)和对照组(5头),试验组饲喂梭立康,对照组不用药,分别于用药前、用药后3 d、6 d和10 d采集各组犊牛粪便进行产气荚膜梭菌计数。结果显示:用药前,试验组粪便中产气荚膜梭菌检出率100%(11/11),对照组检出率50%(2/4,24018无粪样);用药3 d,试验组粪便中产气荚膜梭菌检出率45.45%(5/11),对照组检出率100%(5/5);用药6 d,试验组粪便中产气荚膜梭菌检出率27.27%(3/11),对照组检出率100%(5/5);用药10 d,试验组未检出产气荚膜梭菌,而对照组的检出率仍为100%(5/5)。综上表明,梭立康对犊牛产气荚膜梭菌具有极强的杀灭作用,可显著降低犊牛粪便中产气荚膜梭菌数量,在生产实际中值得推广并使用。
In order to investigate the prevention effect of Suolikang on Clostridum perfringens of calves,sixteen Holstein calves aged 30-60 days were divided into experimental group(11 calves)and control group(5 calves)with complete randomization.The experimental group was feed with Suolikang,and the control group did not take any measure.Feces of calves in each group were collected before medication,3 days,6 days and 10 days after medication respectively to counted the Clostridum perfringens.The results showed that before treatment,the detec-tion rate of Clostridum perfringens was 100%in experimental group(11/11)and that of the control group was 50%(2/4).After 3 days,the detection rate of Clostridum perfringens in experimental group was 45.45%(5/11)and that of the control group was 100%(5/5).The de-tection rate of Clostridum perfringens in experimental group was 27.27%(3/11)after 6 days,and the detection rate of Clostridum perfrin-gens in experimental group was 0%(0/11)after 10 days,while that of control group was 100%(5/5).It can be concluded that Suolikang has strong klling efect on Clostridum perfringens of calves and could reduce the population of Clostridum perfringens in feces of calves signifi-cantly.Therefore,Suolikang is worth to promote and use in actual production.
