Ear Tags by Size

Visual tags several several purposes, from a unique identification (such as ear tag number/management code) to including your ranch name and contact information. Tags are available in 4 different sizes, with each offering a variety of custom options.

  • The two larger sizes of tags, the Super Maxi and the Maxi tags, are most appropriate for mature cattle. 

  • The Large tag works best for calves and smaller livestock, like sheep and goats.

  • The Medium tag should be used for only very small calves or livestock.
