Declarations

:

: The collection and analysis of personal data (i.e., data possibly linked to individual farmers) was approved by the Secretariat at the University of Copenhagen, Faculty of Health and Medical Sciences (Reference number: 514-0480/20-3000). In the design phase of the study, the senior investigators deemed that the described procedures would not cause pain, suffering, distress, or lasting harm to an extent where an approval for experimental animal use was necessary according to Danish law.

: Interviewees (sampling stage 1) gave their oral consent to the use of their data for research purposes, and the owners of the nine included herds were additionally informed by e-mail.

: The authors’ past and present research projects are frequently funded by Danish authorities regulating the pig production and the Danish pork industry through different sources. The authors believe that this has not inappropriately influenced the present work.
