“…The live attenuated CSF vaccine has been widely utilized or made mandatory to control CSFV epidemics [ 3 ]. Despite this increased usage, the emergence of epidemic diseases such as African swine fever virus (ASFV) may lead to ineffective CSF vaccine application in ASFV-affected areas [ 23 ]. Therefore, the development of bivalent or multivalent vaccines combined with PCV2 vaccines may offer an alternative solution to avoid elevated stress from multi-immunization processes and the interference of concurrent infections via PCV2-SI in field farm applications.…”

“…There are various monsoon climates with 3–28°C of annual average temperature and multiple geographic patterns, including plateaus, mountains, plains, hills, and basins. Pigs were divided into six categories according to different age and usage as follows: piglets (from birth to 21 days), weaned piglets (age of 22–70 days), growing-finishing pigs (above 70 days), replacement gilts, multiparous sows (at least one party), and boars ( 23 ). All the selected pig farms were without PRRSV vaccine immunization.…”

“…The ASF outbreak and farm topography variables were treated as binary variables. Farm size was categorized into three groups based on the number of sows: small (≤100), medium (100 to 500), and large (≥500) ( 28 ).…”
