Standard operating procedures (SOP) are increasingly required on farms participating in animal welfare assurance programs, such as the Dairy Farmers of Canada's proAction initiative and the National Dairy FARM Program in the United States. However, little is known about the use of SOP on farms and who is involved in their development. Literature from other industries shows the importance of including advisors when developing SOP. Despite veterinarians being viewed by many farmers as trusted sources of information, little is known about their involvement in SOP development. The aim of this study was to better understand: (1) what advice from researchers and veterinarians is considered when developing an SOP and (2) what factors affect advice adherence. Participants in this study were farmers (n = 9) from 6 dairy farms in the Fraser Valley region of British Columbia, Canada and their herd veterinarians (n = 5). Structured and semi-structured interviews and participant observation were undertaken from April to December 2018, and the resulting data were analyzed using thematic analysis. In relation to the first aim, we identified 3 main themes: (1) the purpose of the SOP, (2) developing an SOP, and (3) accountability and tracking of procedures. For the second aim, 5 themes emerged: (1) feasibility of the advice, (2) resources required, (3) priority of the advice, (4) other actors involved, and (5) the importance of data. Collectively, these findings suggest that a farm-specific SOP that actively tracks procedures is most beneficial, and that advice adherence is context dependent.
