The document describes CowLab, a research environment that utilizes sensors and technology to collect data on dairy cow behavior, health, physiology and production. CowLab allows comprehensive testing of innovations to improve animal welfare and productivity. Sensors can monitor activities like rumination, movement, location, resting, feeding and milking. This large dataset is transferred to a cloud service for analysis and mining to provide new insights. The goal is to use this technology to develop applications and products that can detect illness early and improve dairy cow welfare and production efficiency.
