What does a mare actually experience during an OPU procedure?
Within Equine Care Group, this is not a question we leave unanswered.
Through Equiception (member of ECG), a dedicated study has been designed to objectively assess the mare’s experience throughout the entire OPU process. Collaborating on a research project to better understand how mares truly experience OPU. Working together with Niamh Lewis and Rachel Annan from University College Dublin, Juan Cuervo Arango from Universidad CEU Cardenal Herrera and Janny de Grauw from IVC Evidensia - a group of leaders in their fields come together.
Supported by the Morris Animal Foundation, this research goes beyond assumptions.
We observe and analyze:
— Behavior before the procedure
— Responses during OPU, including potential signs of discomfort or pain
— Recovery and behavior in the stable afterward
By comparing these phases, we aim to build a clear, evidence-based understanding of the procedure.
The study also looks at different mare profiles, from young to older mares, sport mares to broodmares.
The objective is simple:
to continuously refine the protocols, adapt sedation and pain management when needed, and ensure the highest standards of care.
Because progress in equine medicine is not only about what we can do,
but also about how we do it.
