Can digital dermatitis be detected in the milking parlor without washing cows' feet?

Scoring digital dermatitis (DD) in the milking parlor after washing the hind feet of cows has been recommended. However, farmers might be reluctant to perform this washing due to compromised udder hygiene. The objective of this study was to evaluate if DD prevalence can be determined without the washing procedure. A total of 4510 cows from 22 dairy herds were scored for DD in the milking parlor without and with washing their hind feet. In all DD infected herds, DD prevalence was higher when scored with washing. The two methods were highly correlated (r =0.987, P <0.001). Scoring with washing resulted in a median of 32% more detected DD cases with a large variation between herds. Overall, DD measurements without washing the feet of cows should be interpreted with caution.
