Short communication: Evaluation of a foot dirtiness scoring system for dairy cows

Abstract : Lameness in dairy cattle is an important health and welfare concern directly affecting the economic benefits of farmers. Although foot dirtiness is a recognized risk factor for diseases inducing lameness, there is a lack of scoring systems that focus specifically on the foot. Therefore, the aim of this study was to evaluate the reliability of a 3-point dirtiness scoring system recently conceived for the assessment of the dirtiness present at the lower legs and claws of dairy cows. The scores of both the lateral and back views from 4 unfamiliar raters at 4 different times were used to evaluate interrater reliability (3 times) and intrarater scoring consistency (1 time). The findings of this investigation revealed that coefficients for interrater agreement (0.38, 0.62 and 0.63) and rating concordance (0.55, 0.75 and 0.74) of back-view scorings improved over time and were superior or similar to those obtained from lateral-view evaluations (coefficients for interrater agreement = 0.20, 0.35, and 0.69; coefficients for rating concordance = 0.48, 0.59, and 0.78). Additionally, the scoring consistency of the raters using the back-view grid was excellent (Cronbach's α = 0.93). The results suggest that the 3-point back-view dirtiness scoring grid may provide dairy consultants and farmers a reliable and easy tool for assessing cow foot dirtiness.
