^a Farmers could give several answers to these questions, therefore the sum of the percentages can exceed 100 %

^b The vaccinations were grouped based on whether the pathogen affected mainly reproductive performance (Porcine parvovirus (PPV), Porcine reproductive and respiratory syndrome virus (PRRSV) and Erysipelothrix rhusiopathiae), or respiratory (Swine influenza virus (SIV), Porcine circovirus type 2 (PCV-2), Mycoplasma hyopneumoniae, Actinobacillus pleuropneumoniae, Pasteurella multocida and Bordetella bronchiseptica, and Glaeserella parasuis) or intestinal health (Porcine rotavirus type A (PRVA), Escherichia coli and Clostridium spp.)
