The modernization of pig production has led to increasingly larger populations of pigs. This dynamic allows for accelerated production and ensures a steady pork supply but also facilitates the spread of infections. PCV2 is a ubiquitous virus and can cause PCV2-associated diseases, depending on production practices. This study aimed to evaluate the conditions of pig production in the state of Jalisco, Mexico, and correlate them with PCV2. A total of 4207 serum samples from 80 farms were analyzed. Epidemiological data were collected and used to investigate factors associated with PCV2 detection. A relative frequency of approximately 30% was detected, primarily in grower pigs maintained on multisite farms. Several production practices, particularly biosecurity measures, were associated with PCV2 on the analyzed farms.
