NIUJINJIN

NIUJINJIN is an AI cattle weight-estimation and cattle face recognition system that estimates live weight from a phone photo in about three seconds and builds a traceable digital record for every animal.

The system automatically locates 17 body-measurement keypoints, holding weight-estimation error within 3% (model MAPE) with cattle face recognition Top-1 accuracy of 95% or above — no crush scale, no handling stress, and a single phone covers each pen patrol.

The resulting weight and identity data serves as objective evidence for underwriting, claims assessment and live-cattle trade verification, with API integration into ERP and policy systems and growth records traceable from intake to exit.
