The samples were collected from the sows, fetuses (mummified, stillborn) and the weak-born piglets from 9 farms. Four pathogens, such as: Mycoplasma suis (M. suis), porcine circovirus type 3 (PCV3), porcine circovirus type 2 (PCV2) and porcine reproductive and respiratory syndrome virus (PRRSV) were detected in the reproductive disorder cases (P<
0.01), mainly in the co-infection. Among them, M. suis and PCV3 were the two pathogens detected in sows with the highest infection rates of 100% and 55.56% by farms, 85.65% and 39.35% by samples, respectively. M. suis and PCV3 were present in the blood of sows, fetuses (mummified, stillborn) and weak-born piglets, of which the most common were in the weak-born piglets and stillborn. Similarly, co-infection of M. suis and PCV3 was detected in the tissues of weak-born piglets with the highest proportion (64.0%), followed by the blood of sows (32.09%), stillborn (19.35%) and mummified (15.38%), P<
0.001. Other reproductive disorder viral pathogens, such as: ASFV, CSFV, PPV, and PRV were not found in this study. This study identified the important pathogens presenting in the reproductive disorder cases of in the sow farms.
