Approximately 6,000 cows, approximately 378,000 passes checked in three weeks: COW PROTECTOR identified the correct cow in 98%. Missing IDs count as errors.
Every cow is unique. COW PROTECTOR identifies individual cows by camera alone, by coat pattern and body shape, with no collar, pedometer or transponder.
For three weeks in daily operation we checked every pass of approximately 6,000 cows in front of the camera, three times a day: approximately 378,000 identifications. An error is any wrong ID and any pass in which no ID was assigned. The result: in 98% of all passes the system identified the correct cow.
Many published figures count only the animals a system identified at all. On the same counting basis, two recent on-farm studies come to 69–84%. How we measured and how this compares, with all sources, is on the animal identification page.
And identification is only the beginning: knowing which cow is in front of the camera lets us link lameness and body condition scores to the right animal and track changes over time.
