Abstract

This study was conducted to investigate the circulation of PED and TGE viruses in the suckling piglets in Cho Gao district, Tien Giang province, from January 2018 to April 2019. A total of 150 pig farms were surveyed using a structured questionnaire to assess the risk factors associated with PED and TGE viruses infection in the piglets. The pooled fecal samples were collected from each
farm and a total of 150 fecal samples were analysed for identifying the presence of PED and TGE viruses by using rapid agglutination and Realtime PCR techniques. The studied results showed that the infection rate of pig household farm with PED virus by the two above techniques was 10% and
26.6%, respectively. The Kappa index was 0.38. The results of the multivariable logistic regression analysis showed that geographical distributions, big herd size, non-disinfection of the pig pens and the distance less than100 meters between the pig farms were the main risk factors of PED virus infection in the sucking piglets in Cho Gao district, Tien Giang province.
