Heat-detection collars and a breeding desk for 20–200 cow dairy farms
TL;DR Heatcollar puts activity collars on cows at mid-size commercial dairies, flags the ones coming into heat and books an inseminator inside the right window. A pregnancy check follows two months later. Farms pay a collar lease plus a fee for each confirmed pregnancy, so the bill tracks the result they actually care about.
India had 81.4 million adult female cattle and 55.0 million adult female buffalo in 2019[1], and it produced 239.3 million tonnes of milk in 2023-24[2]. A cow earns only after she calves, so every missed heat pushes the next lactation back by about three weeks.
And missed heats are common. A 2026 review puts visual heat detection below 50%[3]. In a field study of crossbred cows in western Uttar Pradesh, only 29.27% conceived under a standard hormone-timed protocol[4]. On a 60-cow farm where the owner also handles milk sales and fodder, who's watching every cow at 2 a.m.? Nobody. What you get is long dry gaps, culled animals and money spent feeding cows that aren't producing.
What it does, in regulatory terms: activity monitoring and breeding alerts only. Heatcollar does not diagnose or treat animals. Insemination, pregnancy diagnosis and any treatment stay with registered veterinarians or trained insemination workers. The Veterinary Council of India keeps the register of practitioners under the Indian Veterinary Council Act 1984[5].
Each cow wears a neck collar that tracks movement and rumination. A model learns her normal pattern and flags the jump in activity that comes with heat. Alerts go to a small desk and not just to the farmer's phone. The desk confirms with the farm, calls a partnered inseminator and logs the service. Around day 60 a vet confirms pregnancy, and cows that didn't settle get flagged for examination.
I narrowed the seed, which pitched broad livestock analytics. Herd-management apps already exist, and one dairy-tech company sells estrus detection with a wearable to dairies at scale[6]. A paid outcome like a confirmed pregnancy is far easier to sell to a farmer than a dashboard.
The farm owner pays. The target is a commercial dairy with 20–200 animals, usually crossbred cows, selling to a private or cooperative dairy. My working assumption is a collar lease of ₹250–400 per cow per month plus ₹500–1,000 per confirmed pregnancy, and both are untested. Collars aren't free either - activity monitors run about ₹2,900–4,350 each (US$30–45)[3]. Milk buyers who want steadier supply could subsidise collars for their bigger suppliers.
Low-power radio devices for Wi-Fi, Bluetooth and Zigbee can be approved by self-declaration at ₹10,000 per model[7], which cuts certification time. Field work published in December 2025 shows how much conception rates move with timing in Indian crossbred cows, from 29.27% to 68.61% with a changed protocol[4]. Dairies are used to digital tools now too, and one dairy-tech company reports 11 million litres a day flowing through its systems[6].
No public figure counts Indian dairies with 20–200 animals or what they spend on breeding. The narrowest signal is uptake of related tools, where that company reports 1 million animals and 2 million farmers on its products[6]. Adjacent - 81.4 million adult female cattle[1], most of them in herds of one to five, which aren't your market.
One Indian dairy-tech company sells a wearable with heat detection and a herd app to several large dairies[6]. An Israeli firm sells collars and pedometers for heat detection to large farms but lists no India presence[8]. Both sell devices and data. The gap is a service that turns the alert into an on-time insemination and charges for the pregnancy.

You can source the collars. The hard bits are tuning heat alerts for Indian crossbreds in hot weather, when activity patterns change, and building a network of inseminators who reach a farm within hours. Collection is the other headache, because farmers pay late when milk prices fall.
Yes, partly. The collars need radio approval, and veterinary work has to stay with registered people.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI to diagnose disease or fertility problems. It flags behaviour, and only a registered vet decides what is wrong with a cow.

I'd say this is worth building for a founder with dairy-farm or veterinary operations experience who can run a field network. It's not for someone who wants to sell hardware and walk away. First prove that collars plus the desk raise conception rates on 300 cows across 10 farms, measured against each farm's own past records.
Plan for roughly ₹1.2–2.2 Cr, mainly collars, a field network of inseminators and the breeding desk. A 300-cow pilot needs far less.
You need WPC radio approval for the collars. Vet work such as pregnancy checks must stay with registered practitioners, and the usual company registration and GST apply.
Yes, wherever mid-size dairies miss heats. Check local radio approval and veterinary practice rules before you launch.

Thinking about building Heatcollar or something close to it? The make-or-break work is getting an inseminator to the cow inside the heat window every single time, and that's an operations problem I like digging into. If you need a hand, you know where to find me. Talk to Yash →
