What Is the AI Cattle Collar and How Does It Work?

The collar, developed by Brazilian agritech startup Cowmed, is a wearable AI device designed specifically for dairy cows. It continuously tracks each animal's feeding patterns, rest, rumination, respiration, body temperature and GPS location. The onboard AI then processes that data to predict whether a cow is healthy or developing an illness β€” and, if sick, whether its condition is improving or worsening under treatment.

Thiago Martins, CEO of Cowmed, describes it as "a smartwatch on the cow's neck, but far more advanced." Farmers such as JoΓ£o Guilherme Brenner, owner of Fazenda Engenho Velho in Belo Horizonte (MG), have been using the collars for up to ten years primarily to help veterinarians manage herd health on a daily basis.

Why Were Livestock Such a Weak Loan Guarantee Before?

Humberto Brenner, director of Target FIDC β€” the firm behind this pioneering deal β€” explains that livestock have historically been "the ugly duckling of the financial system." A cow appraised at R$ 20,000 would typically back only R$ 8,000 in credit, because lenders had no way to verify where the animal was, whether it was alive, or what its health status was. Those unknowns translated directly into penalty rates or heavy discounts on collateral value.

Livestock-backed loans are usually small, covering working capital or harvest costs. As Brenner notes, it makes little sense for a farmer to pledge a R$ 10-million property deed to secure a R$ 300,000 working-capital loan β€” so animals were the natural choice, just an inefficient one.

What Changed With Tokenisation on the B3?

Brazil's first registered tokenised-herd credit operation went live on the B3 (the Brazilian stock exchange). Ten cows from Fazenda Engenho Velho were appraised at R$ 120,000 as collateral, unlocking a R$ 100,000 loan for the farm. Once an animal is tokenised, real-time health and location data flow automatically to a blockchain platform, giving the lender full, tamper-proof visibility β€” and sharply reducing the risk premium.

What Does This Mean for Agribusiness Finance?

The operation signals a potential shift for smaller rural producers who lack large landholdings to pledge. By making livestock collateral more transparent and trustworthy, AI monitoring could widen access to rural credit and lower borrowing costs across the sector.

Key Facts:
  • First tokenised-herd credit deal ever registered on Brazil's B3 exchange.
  • 10 cows appraised at R$ 120,000; R$ 100,000 loan released to Fazenda Engenho Velho (Belo Horizonte, MG).
  • AI collar developed by Cowmed tracks feeding, rest, rumination, temperature, respiration and GPS location.
  • Previously, a R$ 20,000 cow backed only R$ 8,000 in credit due to lender uncertainty.
  • Operation structured by Target FIDC; data stored on blockchain for lender access.
