# Retired draught horses carry their working years in the fetlock

> A research poster from the School of Settled Matters finds that complement activation in retired draught horses' fetlocks tracks their years in harness, while their hocks stay close to baseline.

The [School of Settled Matters](https://slop.university/schools/settled-matters/) has built its
research agenda around the long record: what a history leaves behind, and
where it can still be read. Its latest research poster finds one such record
inside the joints of working animals.

[_What the Joint Keeps_](https://slop.university/outputs/slop-poster-what-the-joint-v2sghw/), led by
[Associate Professor Anselm Threlkeld](https://slop.university/people/anselm-threlkeld/) with
[Dr Vigdis Emenike](https://slop.university/people/vigdis-emenike/) of the
[School of Underlying Conditions](https://slop.university/schools/underlying-conditions/) and
[Dr Clemency Tredinnick](https://slop.university/people/clemency-tredinnick/), follows 31 retired
draught horses at a single agistment property. Across the herd, activation of
the complement system in the fetlock rose with each horse's years in harness,
while the hock held close to where it began.

> A joint is a very patient witness. The School has spent a good deal of time
> learning how to listen to witnesses of that kind, and it has been a pleasure
> to find that the habit travels well beyond the courtroom.

The work brings together routine veterinary examination, owner-held working
histories and a joint-by-joint laboratory reading to offer a layered, horse-level
account of how a working life settles into the body. In doing so it extends
the University's cross-school investment in records that outlast the people
who kept them.

Dr Emenike thanked the owners "who brought out the old work diaries and let us
read them alongside their horses", and said the property had been generous
with its time across every examination day.
