    Snippet: According to the previous study, there was a high prevalence rate of PED in pig herds [3] . Clinical signs of PED are seen in piglets within 7 days of birth and present as vomiting and aqueous diarrhea. Death rates during this stage range from 80% to 100% resulting in huge economic losses in the pig industry [17] . During the period from 2010 to 2013, the incidence of diarrhea among newborn piglets from 60 large-scale farms in Guangdong and some .....
    Document: According to the previous study, there was a high prevalence rate of PED in pig herds [3] . Clinical signs of PED are seen in piglets within 7 days of birth and present as vomiting and aqueous diarrhea. Death rates during this stage range from 80% to 100% resulting in huge economic losses in the pig industry [17] . During the period from 2010 to 2013, the incidence of diarrhea among newborn piglets from 60 large-scale farms in Guangdong and some other southern provinces was 59,320, of which 45,601 piglets died, for an average mortality rate of 76.87%. These studies indicate that PED is an increasingly serious problem in China.
