Strategies and technologies towards reduced lameness in cattle

Lameness is the third most impactful disease in dairy cattle, with respect to economics and animal welfare

Lameness is not a single disease; it has multiple causes and, as such, is difficult to assess, diagnose and treat effectively

Whilst new technologies aimed at diagnosing lameness are available (or in production), a key factor in reducing prevalence thereof throughout the UK, is a necessary change in perspective and an overhaul of the management practices commonly used in the dairy sector.

What is lameness

Lameness is considered one of the most detrimental diseases (behind reproductive issues and mastitis) currently affecting the dairy industry globally. Associated economic losses include reductions in milk production, limited reproductive performance and increased animal mortality, emphasised by escalated levels of animal culling. Lameness in cattle is defined as any variation/defect which causes abnormalities in a cow’s gait and can include a variety of leg and foot conditions. However, studies suggest 90% of lameness is directly related to diseases of the foot. Diseases of the foot are split into infectious and non-infectious diseases, of these, previous research has suggested that the most commonly occurring are sole ulcers, with an estimated individual cost of £518.73 per case, followed by white line disease estimated at £300.05 per case. The most prevalent infectious disease, on the other hand, is suggested to be Digital dermatitis (DD), though estimated costs per case for this are low, £75.57 per case, it is, however, highly contagious and therefore poses a further risk to the herd as a whole.
