The cattle tag business has grown substantially in recent years on the back of continued expansion in the national dairy herd. The peak sales season has also become more condensed in Ireland with upwards of 70% of dairy births taking place from January to the end of March.

The rush to order tags has been spread over three companies in recent years following Cormac Tagging and Datamars securing approval to supply tags along with Mullinahone Co-op. Despite this, it is still a busy season.
