Cattle identification ear tags can be a very useful management tool. However, in some situations after tagging an infection may develop around the point of insertion especially in young calves. To help reduce the risk of infection try to keep hands clean and disinfect ear tags (focus on the part that will touch or penetrate the ear) and the end of the applicator that holds the tag with alcohol or another disinfectant. Watch for any ears that are drooping and signs of infection. With calves it may be necessary to temporarily remove the tag to allow for healing.
