4Including 17 newborn piglets.

5Pigs slaughtered before the discovery of the outbreak.

6Hybrids were bought from another outdoor piggery for breeding purposes. In this other piggery, however, hybridization had been accidental (wild boar intrusion).

7A breeding domestic sow, which had mated with a wild boar (accidental intrusion), was bought pregnant of hybrid piglets from another outdoor piggery

8Sampling on request of the pig owner.

Sampled domestic pigs from Swiss outdoor piggeries (P) in 2008–2010 in a study on risk factors for contacts between wild boar and outdoor pigs. Categories of contacts: (1) presence of wild boar around the enclosure (> 2 m); (2) presence of wild boar just outside the fence (< 2 m); (3) wild boar intrusions without mating; and (4) mating (hybrid births).
