Prevalence of coccidian infection in suckling piglets in China.
To determine the prevalence of coccidian infection in suckling piglets in China, fecal samples from 779 litters of suckling piglets were collected on 80 different farms in 17 provinces from September 2009 to December 2010. These samples were examined through saturated saline flotation technique. The prevalences of coccidian infection ranged from 0 to 32.5% among different provinces and the average was 16.7% (130/779). The highest prevalence of 19.9% (69/346) was found in 8-14 day-old litters of suckling piglets. Seven coccidian species were detected in the positive litters of suckling piglets, including Isospora suis (63.9%), Eimeria debliecki (46.9%), Eimeria polita (19.2%), Eimeria suis (20.8%), Eimeria perminuta (13.9%), Eimeria scabra (4.6%), and Eimeria yanglingensis (1.5%). 55.4% of the positive litters of suckling piglet infected more than one coccidian species. The results of this investigation will provide the relevant basic data for control strategies against porcine coccidiosis on pig farms in China.
