Wayne and Todd’s Big (Ketosis) Adventure

Move over the Rolling Stones, Coldplay and Joe Cocker because two veterinary big names from Canada are set to tour Europe in May. Experts Professor Todd Duffield and Wayne Shewfelt will be lecturing an invited audience of veterinary surgeons on ketosis in the dairy cow in venues in Italy, Germany, and the Netherlands; landing in Ireland on the 10th May and the UK on the 13th May for a two venue appearance.

While the event, organised by Elanco Animal Health, promises to be a veterinary VIP exclusive, any vet with an interest in dairy herd health monitoring can register their interest in obtaining a ticket to attend the UK ‘gigs’ by sending an email to elancouk@lilly.com, or calling 01256 353131.

Professor Duffield brings with him a wealth of expertise in herd health management and dairy research including specific knowledge of metabolic diseases affecting the dairy cow. Wayne Shewfelt is a partner in a 15 vet practice in Canada that provides healthcare for around 14,000 cows. With many years of practical experience in proactive herd health monitoring for ketosis and intervention strategies to help farmers manage ketosis to acceptable levels, Wayne has much to share with vets in the UK.

Wayne and Todd’s UK dates will see them in Bristol on the 13th May and Manchester on the 14th May for a full day seminar to talk about the opportunities offered to vets by being proactive in tackling ketosis and subclinical ketosis. With this metabolic disease being associated with an increased risk of metritis, retained placenta and left displaced abomasum,1 the condition is highly relevant to vets involved in improving the health, welfare and productivity of dairy cows.

Vets who would like to attend the seminars should contact Elanco Animal Health as soon as possible as tickets are sure to be in hot demand.
