The project.
The management app is up and running, and a veterinarian is evaluating it. The male's device is designed and its logic is written; what's left is to build it and take it to the field, where ideas either break or prove themselves.
Two failures no one solved.
Heat-detection technology has been around for years. It just wasn't designed for this animal, this place, or this budget.
The Buffalo's Blind Spot
Buffalo heat is mostly silent, happens at night, and often with the animal submerged in ponds or mud — exactly where conventional sensors, built for stabled dairy cows, suffer total signal attenuation.
- Silent
- Nocturnal
- Submerged
The Economic Barrier
Fitting every female with an active collar costs €100+ per animal. On an average farm, the upfront investment becomes prohibitive — so heat detection is still done by eye, with the cost piling up every day.
- €100+ / collar
- €4 / open day
The model fits in one line.
There's no magic in the savings: idle days simply stop existing. The rest is arithmetic — and it's open to scrutiny.
Annual Savings = N × ΔD × C_diário- N
- Herd size100 females
- ΔD
- Average reduction in open days15 days
- C_diário
- Cost of an empty animal, per day€4 / day

What's locked in, and what's left.
The app already works. What's left is building the device and taking it to the field — and that's what the 2027 pilot will pay for.
System architecture
DoneA single device on the male and low-cost tags on the females: the design that makes the system affordable is locked in.
Breeding management app
DoneUp and running: the herd, each animal's record, heats, inseminations, pregnancy checks and calvings — offline too, in the field — and phone alerts when it is time to inseminate.
Veterinary review
In progressA veterinarian is evaluating the app and reviewing the parameters for each species before we use them with producers.
Device logic
In progressThe device's "brain" is written and tested on a computer. Next, it goes onto the first boards.
First physical devices
PlannedBuilding the first units and lab-testing them — they have to survive under water.
Real-world pilots
PlannedCattle herd in Viseu and buffalo herd in Ribatejo — the only place where the algorithm proves itself.
Here's what it will look like in the field.
AI-generated illustrative concepts to visualize the device in use — not photos from a real pilot, which only starts in 2027 (see Roadmap).
