Abstract
In order tofind out the causes of piglet diarrhea and its epidemic status in Dazhu county,a comprehensive survey on 90 700 piglets from 56 farms in 41 townships were conducted by investigation,retrospective survey,field survey,clinical diagnosis,laboratory testing and some other methods. The results showed that the piglet diarrhea was a severe disease in Dazhu county and presented wide prevalence,the incidence rate was 50.32%,and the causes were complex. There were non-pathogenic factors and pathogenic factors. Non-pathogenic factors were closely related to season,parity,piglet ages,piglet supplementary feeding,feed sources,situation of expelling parasites,sow health and the integrated environment in breeding houses. Pathogenic factors includedE.coli,Clostridium perfringens, Serpulina,Transmissible gastroenteritis virus,Totavirus and parasites,in which theE.coli was the major pathogenic microorganism and the mainE.coli serotypes were O20,O101,O141. The isolates showed severe drug resistance and multiple resistance. Therefore,it should be applied an integrated management instead of aiming at only one factor to prevent and control the piglet diarrhea so as to achieve the purpose of improving survival rate of piglets and rearing rate.关键词
