Advisor: Gerard Cramer. 1 computer file (PDF); 153 pages.Lameness is a leading animal welfare issue and management challenge in the dairy industry. Using a combination of quantitative and qualitative methods, this thesis examines causes of lameness, barriers faced by stakeholders, and ways to facilitate collaboration between lameness advisors. The first objective of this thesis was to investigate how metabolic changes may impact the structure of the foot and predispose cows to sole ulcer and white line hoof lesions (Chapter 2). Given the multiple stakeholders involved in lameness management on a dairy farm, the second objective of this thesis was to explore farmer, hoof trimmer, and veterinarian perceptions of the barriers to lameness management (Chapter 3). Furthermore, we also aimed to identify stakeholder perceptions of their own role in lameness management as well as their expectations of other stakeholders. Improved understanding of roles and expectations will aid in developing interventions with stakeholders. Given the importance of farm advisors in delivering advice and support, the final objective of the thesis was to increase collaboration between hoof trimmers, veterinarians, and nutritionists through facilitating lameness management advisory teams (Chapter 4). This research contributes to our understanding of the role of farmer, hoof trimmer, nutritionist, and veterinarian stakeholders in lameness management and how best to foster and support collaborations between multiple stakeholders to improve lameness management.enadvisor engagementcow welfareThesis or Dissertation
