Analysis of Cattle Foot Lesions Recorded at Trimming in the Southwest of England.

backgroundThe UK has a high incidence of lameness in cattle, which is costly in terms of economics and welfare. Most causes of bovine lameness originate in the foot but there are several different conditions causing lameness. Quantifying the relative prevalence of different lameness causing lesions allows for the focus of preventative measures and research on the most common conditions.

methodsThis study analysed trimming records from 23 professional foot trimmers working in the Southwest of England. A total of 97,944 recorded lesions over a 5-year period were analysed for lesion identity, lesion severity, repeat presentation, foot affected, claw affected and whether they were from dairy or beef cattle.

resultsThe most frequently recorded lesions were digital dermatitis (32%), white line disease (21%), sole ulcer (19%) and sole haemorrhage (13%). White line disease had the highest percentage of lesions requiring veterinary attention and most frequently re-presented. Most lesions were in hind feet and there was a small but significantly greater number recorded in right feet. Beef cattle had a higher percentage of digital dermatitis and lower percentage of sole ulcer compared with dairy cattle.

conclusionsDigital dermatitis was the most common foot lesion of all cattle types. Most feet with lesions only appeared in the data set once, suggesting broadly that foot trimming was largely effective at resolving new foot lesions. More white line lesions were re-presented, along with having more severe grades compared with other lesions. Therapeutic trimming of chronic lesions appeared to be less successful, with re-presentations, on average, every 93 days, compromising welfare for extended periods, and requiring consideration of different veterinary treatment options.
