Instant Insights: Lameness in Dairy Cattleav Dr Zoe E Barker, Dr Nick J Bell, Dr Jonathan R Amory, Professor Edward A Codling, Dr Christa Egger-Danner569
This collection features four peer-reviewed literature reviews on lameness in dairy cattle. The first chapter provides an overview of lameness and its impact on dairy cow health and welfare. The chapter reviews existing methods for manual and automated detection of lameness, including approaches that detect changes and abnormalities in the gait, stance and behaviour of the animal, including the use of video, accelerometers and spatial positioning systems. The second chapter discusses the aetiology of the four main causes of lameness in dairy cows: sole ulcer, white line, digital dermatitis and interdigital phlegmon. The chapter reviews the importance of prompt and effective treatments, as well as the best practices to optimise foot health to prevent the onset of lameness. The third chapter reviews advances in dairy cattle breeding to improve resistance to claw and foot disorders, primarily lameness. It considers the various steps in breeding, from the definition of the breeding goal to genomic evaluation and data validation, as well as the consequent challenges which can develop. The final chapter examines the impact of lameness on dairy production and highlights the importance of optimising foot health in dairy cattle to prevent the occurrence of lameness. The chapter discusses claw horn disruption and concludes with a case study on an outbreak of lameness in a herd of 800 Holstein cows.

Since 2012 we have been working with a range of collaborators on our ongoing Cow Tracking Project. We are using novel tracking sensors to automatically monitor the movement and behaviour of dairy cows. Using the collected data, we can determine patterns of behaviour that may be indicative of changes in health, or relate to important events such as calving. We work closely with farmers and the dairy industry to ensure that our research findings can be used to improve farm efficiencies and animal welfare.
