A total of 6 focus groups involving 35 participants from 30 farms were held in Ontario Canada from February 5, to March 8, 2024. Twenty-five (71%) individuals who identified as a man and ten (29%) who identified as a woman. Participants were on average 39 years old (median = 37, range = 20 to 80). Twenty-three of the farms (77%) were freestall and seven (23%) were tiestall. Sand bedding was used by 14 farms (47%) and combinations of shavings, straw and mats were used by 16 farms (53%). Farms had an average of 105 lactating cows (median = 82, range = 40 to 425).

2024年2月5日至3月8日，研究团队在加拿大安大略省共开展6场焦点小组访谈，招募了来自30个牧场的35名参与者。其中25名（占比71%）性别自我认同为男性，10名（占比29%）性别自我认同为女性。参与者平均年龄为39岁（年龄中位数为37岁，年龄跨度为20至80岁）。30个受访牧场中，23家（77%）采用散栏式饲养模式（freestall），剩余7家（23%）采用拴系式饲养模式（tiestall）；14家牧场（47%）使用沙子作为牲畜垫料，16家牧场（53%）采用刨花、秸秆与防滑垫的组合垫料。受访牧场平均饲养泌乳奶牛105头（饲养规模中位数为82头，范围为40至425头）。挤奶系统配置方面，10家牧场（33%）采用挤奶厅挤奶模式，13家（43%）使用自动挤奶系统（automatic milking systems），剩余7家（24%）采用其他类型挤奶系统。
