Table 3 Different management practices related to biosecurity, as reported by the surveyed Swedish pig farms, in the dry sow sections (deep litter straw or conventional pens with limited bedding material) divided by farm size (for clarification of herd sizes, see Table 1). Different letters within a row indicate a statistical difference (p < 0.05) between herd sizes. The differences were compared statistically using Chi-square tests. When numbers are written in italics, the distribution of the responses did not allow for chi square analysis
