Allflex Livestock Intelligence—part of MSD Animal Health Intelligence—has been at the forefront of animal identification and traceability for more than six decades. Founded in New Zealand in 1955, the company introduced the first flexible plastic ear tag for livestock, setting the stage for innovations that would revolutionize the livestock industry. In the early 1990s, Allflex pioneered electronic RFID tags, enhancing the speed and accuracy of livestock data collection.

Today, Allflex provides a wide range of solutions including visual and electronic identification tags, tissue sampling devices, readers, monitoring collars, and data analysis systems. These technologies support critical farm functions such as health monitoring, reproduction tracking, feeding management, and milking control. The brand’s integration into MSD Animal Health in 2019 strengthened its ability to combine animal identification with advanced digital health solutions.

With manufacturing and distribution facilities in North America, Europe, South America, China, Australia, New Zealand, and India, Allflex delivers hundreds of millions of tags annually and monitors millions of animals worldwide. Its mission is to empower farmers with intelligent data that improves animal health, enhances productivity, and ensures a more sustainable global food supply.
