About DMI Impact

A decade in the barn, answering one question: could you get her to eat?

DMI Impact was worked out over more than ten years on six US commercial dairies, by the late Dr David Barcik and a team who spent that decade with fresh cows. R.T. Barcik is now carrying the work to British and European dairy.

Why now

Ahead of its time then. On time now.

The work began before the industry was looking for it. The industry has since arrived at exactly the problem it set out to solve.

Then

Built and tested on commercial dairies through the 2010s

When the work began, transition-cow biology was a specialist’s concern, wearables on cows were a novelty, and getting a fresh cow to eat wasn’t something anyone thought a farm could change.

Now

The industry has caught up

Transition management is a recognised priority. The kit that records what a cow does is on roughly three dairy farms in five, and herd health is now treated as an emissions question, measured per litre.

Approximately 3 in 5 dairy farmers utilised automated cow monitoring technology: Barraclough 2020 · UK · Kyriazakis et al. 2024 · UK-led review

The people who built it

Built by people who were in the barn.

Scientists who invented and researched it, a vet who watched the cows, and the dairy people who fitted the units on their own fresh cows and lived with the results.

The late Dr David Barcik

Inventor

More than a decade on the transition-cow problem: inventing, refining and testing the device on commercial fresh cows until it worked.

The late Dr David Paskewitz

Research and development

Led the research and development that turned years of fresh-cow observation into a working, repeatable device.

Dr Kerry McGehee

Veterinarian

Clinical oversight on the dairies where it was used, cow by cow and transition by transition.

Johnny Legg

Owner, Turnpike Dairy and Legg Cattle Company

Turnpike Dairy was the original trial dairy: fresh cows carrying a device on a working commercial farm.

Jeremy Setters

Herd Manager

Has fitted several hundred units with his own hands, more than anyone, and watched what the cows did next.

R.T. Barcik

Founder

Carrying the work to British and European dairy, and the sole decision-maker for DMI Impact. He fronts the films and answers the questions himself.

It was invented and researched by the scientists, kept honest by the vet who watched the cows, and proved on the farms that ran it on their own fresh cows, Turnpike Dairy first among them.

John Legg Jr and Bret Barcik also contributed to the work in its first decade, alongside the six named above.

What we stand for

Cow first, evidence-led, and never more than the data can carry.

Three commitments that don’t move, however the work grows.

Mission

Help every fresh cow eat her way through

Support the one thing behind her whole lactation, her dry matter intake, through the three weeks after calving.

Vision

A behavioural tool for dairy

Something that acts on what the cow does, alongside the collars, boluses and meters that already measure it, without asking anything of the ration.

Values

Check us; don’t just trust us

Every claim traced to one of more than 150 sources we hold in full. The conservative number first. And on every measured figure, the caveat on its face: a percentage increase is anecdotal until scientific studies verify the correlation and the causation.

Barn to boardroom

A family’s work, carried forward.

What began as one man’s decade of asking whether you could get a fresh cow to eat is now being carried to British and European dairy by R.T. Barcik. The same idea, the same evidence, and the same refusal to overstate it: from the barn, where it has to be true, to the boardroom, where the case is made.

No farm in Britain has run one yet. The first herds to do so will be the ones the industry watches.

Reverent to the science, and to the man who spent a decade proving it.
