Cows with Neurochips Appear on Russian Farms

NeuroRoga, a subsidiary of Neiry, has completed the second stage of an experiment aimed at increasing livestock efficiency through neurostimulation.

In August, NeuroRoga scientists successfully performed surgeries on five cows with a 100% survival rate. During and after the operations, the animals remained conscious, felt well, experienced no discomfort, and have already returned to their normal production cycles on the farm.

Each cow received custom-designed electrodes developed by the company. The research team is currently selecting the optimal stimulation program to ensure a stable increase in milk yield. For example, when a cow’s appetite decreases, the system automatically adjusts the neuromodulation mode to restore it. The resulting effect on the animal’s physiological productivity — such as milk output — is then measured.

The implantation procedures are carried out in a mobile neurosurgical operating unit, a unique development by NeuroRoga. This setup significantly reduces both the cost and duration of the operation — to just 30 minutes — without requiring farmers to make major changes to their infrastructure or production processes.

Neiry’s scientists continue working on further reducing the implantation time, aiming to make the procedure as simple and accessible as possible — ultimately to the point where an ordinary veterinarian can perform it directly on the farm. In the long term, the installation of neuroimplants is expected to become a routine practice, seamlessly integrated into daily livestock management.

Through neurostimulation, specialists plan to gradually enhance key health and productivity indicators in animals: improve appetite, reduce stress levels, boost milk letdown, and increase overall activity. The stimulator’s electronic unit is attached to the back of the animal’s head, with electrodes reaching deep into specific brain regions — including those responsible for reproductive functions. This targeted stimulation leads to long-term improvement in milk production.

According to investors, as traditional methods of increasing milk yields have nearly reached their limits, neurointerfacescould become a new competitive advantage for the industry. Current testing confirms the technology’s potential, but further research and development are needed before mass implementation.

NeuroRoga is now moving toward its first commercial deployment, during which more than 20 cows will receive neurostimulation implants.
