The Canadian Cattle Identification Agency has released its final report on its tag retention project. The four-year study tracked 2,000 calves, 1,000 yearlings, and 700 cows with RFID ear tags.
The overall tag retention rate for calves exceeded 96 per cent while tag retention for yearlings ranged from 98 to 100 per cent. However, the average tag retention rate for mature cows was 82 per cent — an “unsatisfactory” level, said Paul Laronde, the organization’s ag and technology manager.
A followup will look at tag material degradation that results in tag loss. The full report can be found on the home page of canadaid.ca.
