Description
Book SynopsisThis 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.
