Simple Summary: This study examines the impact of employee-related factors on udder health in dairy cows. Specifically, it investigates how variables such as educational level, the nature and scope of training provided, the methodologies utilized in that training, and the adherence to Standard Operating Procedures (SOPs) within a dairy herd influence Bulk Tank Somatic Cell Count (BTSCC) and new infection risk. We anticipated that employees with formal education and comprehensive training in SOP implementation would be associated with lower BTSCC and new infection risk than their counterparts lacking formal agricultural education. Our findings indicate that the presence of an SOP correlated with an increase in BTSCC by 21,600 cells/mL compared to herds lacking a milking SOP. Furthermore, we observed a reduction of 0.02% in new infection risk when employing educated staff, which decreased to 0.16% when an SOP was incorporated into the training regimen. In contrast, unskilled employees were linked to a 0.02% increase in new infection risk. Notably, the availability of an SOP in the herd that was not incorporated within the training was associated with a 0.15% increase in infection risk. These results underscore the importance of combining foundational knowledge with implementing SOPs in training programs to optimize milking protocols. For decades, bovine mastitis and milk quality have been a focus area for research, agricultural extension, and dairy processors worldwide, yet employee management as a factor in udder health management has received limited attention. This is mainly because the focus has previously been on more classical areas covered by the National Mastitis Council Mastitis Control Program (NMC 10-point plan) in English-speaking countries. Therefore, we wanted more background information on employee management on dairy farms, to identify the human factor of udder health management. The method of investigating employee management and the impact of employee management on udder health was conducting a study of 88 Danish dairy farms with hired employees and parlor or rotary milking systems. An interview-based questionnaire on individual dairy farmers' human resource management was developed based on the current literature and multiple discussions among the authors. The results we found through analyzing associations between the dependent variable BTSCC and employee management, using a regression model, was that providing a generic SOP was associated with a 21,600 cells/mL increase in BTSCC, with estimates in the range (507; 42,674 cells/mL). We also analyzed, applying a Poisson model, that there was a 0.16% reduction in new infection risk if the training was based on a herd-specific SOP and educated employees. In contrast, we identified a 0.15% increase in new infection risk in herds where SOPs were available but not incorporated, both modest but significant results. In conclusion, farms with educated employees and trained by an SOP achieve the lowest new infection risk, but education has no impact on BTSCC. [ABSTRACT FROM AUTHOR]
