  • The contribution of each nursery unit (N1 and N2) on the combined (both units) mortality rates between three and ten weeks of age is presented separately. All mortality rates were calculated according to the total number of animals included in the non-vaccinated (NV; batches A and C) and vaccinated (V; batches B and D) farrowing batches upon transfer to the nursery units.

  • Vaccination status: NV (pigs originating from non-vaccinated sow farrowing batches) and V (pigs originating from vaccinated sow farrowing batches). Values with different superscripts within a row are significantly different (P<0.05 and P*<0.05). The P value refers to the comparisons between the summaries of the NV (A–C) and V (B–D) batches concerning the pigs that died showing signs of EE and the P* value to the comparisons between the summaries of the NV (A–C) and V (B–D) batches concerning the pigs that died from all causes.
