- Abstract
Biosecurity protocols and good management practices are key to reduce the risk of introduction and transmission of infectious diseases into the industry. In this observational cross-sectional study, survey data were collected from 176 pig farms with inventories over 100 sows in Colombia. We analyzed a complex survey dataset to explore the structure and identify clustering patterns of swine farms in Colombia, and estimate its association with Swine Influenza. Two principal dimensions contributed to 27.6% of the dataset variation after Multiple Correspondence Analysis. Farms with highest contribution to dimension 1 were larger farrow-to-finish farms, using self-replacement of gilts and implementing most of the measures evaluated. In contrast, farms with highest contribution to dimension 2 were medium to large farrow-to-finish farms, but implemented biosecurity in a lower degree. Additionally, two farm clusters were identified by Hierarchical Cluster Analysis, and the odds of influenza A virus detection was statistically different between clusters (OR 7.29, CI: 1.7,66, p=
