The Next Frontier in Dairy · The Solution
Get her to eat — and the whole cascade stays ahead of the gap.
You've seen the biology and the bill. Both trace to one number: how much she eats in the first three weeks. DMI Impact is a wearable neurostimulation device that supports that one lever — her dry matter intake — and asks nothing of the ration.

How it works
One simple loop, on every fresh cow.
The device doesn't feed her and it doesn't medicate her. It works through the nervous system she already uses to decide to eat — supporting her own drive to get to the bunk, when it matters most.
STEP 01
Fit
The sleeve is fitted chute-side in about ten minutes. The device rides externally across her ~21-day transition — nothing enters the cow.
STEP 02
Prompt
Programmed, gentle neurostimulation between milkings supports her own feeding behaviour — the signal runs through the nervous system she already uses to eat: brain, brain stem and spinal cord.
STEP 03
Eat
She goes to the bunk more often between milkings. Dry matter intake rises — the one lever that sits behind the whole transition cascade.
STEP 04
Recover
Higher intake helps her recover energy balance sooner, so milk, condition, health and fertility stay ahead of the gap instead of falling behind it.
↻ One unit, one fresh cow at a time — then cleaned, refitted and reused on the next.
What it is — and what it isn't
A device that acts on the cow, not around her.
A new behavioural class of intervention: it supports the cow's own feeding drive, and asks nothing of the ration, the milk or your routine.
What it is
- A wearable neurostimulation device, worn externally across the ~21-day transition.
- It supports her dry matter intake by working through her own nervous system — brain, brain stem and spinal cord.
- Fitted chute-side in minutes; reused on the next fresh cow.
- A new behavioural class of intervention — it acts on the cow's own biology.
What it isn't
- Not a drug, hormone or antibiotic.
- Not a ration change or a feed additive.
- Nothing enters the cow — and nothing enters the milk.
- No withdrawal, no residue, no change to how you feed.
The same six lines — the other way
Move the one lever, and the bill starts to run in reverse.
On the Cost page, low transition intake ran up six bills — conservatively ~£302k+ per 1,000 cows. Every one of those lines traces to intake, so every one has a second side when intake is supported.
Low intake — the billIntake supported — the other side
Lost milk
litres never made in the fresh period
→
Milk kept
more of the lactation stays in the tank
Body condition
~0.9 BCS burned and rebought
→
Reserves spared
less of her own body spent to cover the gap
Disease
cows tipped into ketosis, metritis, DA
→
Fewer tipped over
more cows carried through the window
Fertility
later conception, more days open
→
Back in calf sooner
condition held for earlier cyclicity
Emissions
higher carbon per litre
→
Lower intensity
maintenance diluted over more milk
Early culling
cows leave before they repay rearing
→
More cows repay
fewer forced exits in early lactation
Honestly framed: the milk uplift is measured in DMI Impact's commercial trials (see Proof). The other five follow the same biology and are associated outcomes of higher intake — supported, not guaranteed. Verbs kept to what the evidence carries.
Not a prototype — a proven build
Ten years and six dairies in the making.
DMI Impact was invented and validated by the late Dr David Barcik with a working team of researchers, a vet and commercial herdsmen — on real fresh cows, in real barns, over more than a decade.

Our own data. The development programme behind this page — six US commercial dairies, more than ten years, thousands of fresh cows — is a commercial-trial programme and is not peer-reviewed. We say so wherever a figure from it appears. An independent UK farm trial is the next step, and it is exactly what a free trial sets up.
Now see it measured on real cows.
