Fig. 4From: Epidemic strain YC2014 of porcine epidemic diarrhea virus could provide piglets against homologous challengeNucleocapsid protein specific antibodies and neutralizing antibodies detection. Data were shown as mean±S.D. a Nucleocapsid protein specific antibodies detection in sera samples of the immunized sows. b Neutralizing antibodies detection in sera samples of the immunized sows. c Neutralizing antibodies detection in the colostrum and the milk on 7th day after farrowing. * Indicates the neutralizing antibody titer of the YC2014 PEDV strain immunized group was significantly higher than the other three groups (P < 0.05)Back to article page
