Table 2 Different management practices related to biosecurity, as reported by the surveyed Swedish pig farms, in the farrowing, grower, and fattening sections divided by farm size (for clarification of herd sizes, see Table 1). Regarding total numbers, different letters (a-c) within a column indicate a statistical difference (p < 0.05) between age categories. Regarding herd sizes, different letters (d-e) 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
