Livestock monitoring is quietly becoming one of the most practical applications of edge AI. The herd is turning into a sensor network: smart collars, barn cameras, cough-detecting microphones, and autonomous drones. The real shift isn't measurement, it's prediction. Models learn each animal's normal baseline and flag deviations days before a human would notice lameness, respiratory disease, or a missed heat cycle. The money agrees: Halter raised $220M at a $2B valuation in March 2026 for solar-powered cattle collars, while YC-backed GrazeMate is using reinforcement learning to let drones muster cattle autonomously. Lab accuracy is excellent (often above 90% for tasks like lameness and body condition scoring), but farms experience accuracy as alert quality. At low disease prevalence, even a strong model can drown a farmer in false positives. The winners won't be the best classifiers. They'll be the systems that fit into a farmer's day: tuned thresholds, few but trustworthy alerts, edge inference that survives bad connectivity, and data the farmer actually owns.
