A short questionnaire was created to obtain site demographics including province, the detection and diagnosis of Lawsonia intracellularis in the past 2 years, the use of L intracellularis vaccines before 2021, the strategy of ongoing L intracellularis vaccination, the presence of clinical signs of enteric disease, or common endemic diseases (eg, porcine reproductive and respiratory syndrome virus, porcine circovirus type 2, and Mycoplasma hyopneumoniae). The questionnaire was distributed to herd veterinarians of enrolled sites at the beginning of the study via Microsoft Teams (Microsoft Corporation), completed by the veterinarian at the time of sampling, and returned to investigators over the course of the study.
The questionnaire should appear as an embedded PDF below or you may download v32n4p156suppl.pdf directly.
