About this episode
Eleanor Brady discusses the importance of clostridial vaccination in sheep flocks before lambing and best practices for vaccine administration.
Eleanor Brady, Ruminant Veterinary Manager with MSD Animal Health, joins us to discuss the critical role of clostridial vaccination in sheep flocks ahead of lambing. Eleanor outlines the impact of clostridial disease and the significant losses it can cause if not properly controlled. We explore the optimal timing of vaccination in ewes before lambing, how to maximise passive transfer of immunity to lambs through colostrum, and what this means for early lamb protection. We finish by discussing best practice when handling and administering vaccines to ensure maximum efficacy.
