Allflex Livestock Identification Tags

Allflex is a global leader in livestock identification, providing essential tools such as ear tags, electronic identification (EID), and monitoring systems for animal health and traceability. The brand serves farmers and livestock managers worldwide, helping them optimize management practices and ensure animal welfare through data-driven insights.

Originally established in New Zealand in 1955, Allflex quickly redefined the livestock industry with the invention of the first flexible plastic ear tag. Over the decades, it expanded globally, becoming the standard for animal identification. Since 2019, Allflex has been part of MSD Animal Health (known as Merck Animal Health in the United States and Canada), following the acquisition of Antelliq by Merck & Co. Manufacturing occurs across several international hubs, including facilities in France, New Zealand, Brazil, and the United States, to support global agricultural demand.
