Lameness is the most significant challenge for the dairy industry to overcome given its obvious disruption of animal welfare and severe economic losses. Sole ulcers and white line abscesses are ubiquitous diseases with chronic nature and with the highest associated economic losses amongst all foot lesions. Their underlying causes are still not fully understood. The objectives of the study were to assess the association of digital cushion thickness (DCT), the risk of claw horn disruption lesions, and to assess the dynamics of DCT by stage of lactation and body condition score (BCS). It was hypothesized that DCT would be negatively associated with the risk of digital lesions and that DCT would be positively associated with BCS.
