USDA tags (United States Department of Agriculture) have a unique 15 digit number starting with "840", display the USDA shield emblem and a "Unlawful to Remove" print. A Premises ID is required to purchase USDA tags. These are ideal for pigs and hogs moving extensively, especially across state lines, and ensure compliance among different states.
Lightweight EID tags are ideal for use with smaller stock. These tags are a bit smaller than the standard EID tags, so do not cause as much weight on smaller ears.
Integra Hog Male tags lay flat to resist snagging and chewing. The large panel allows for good visibility of the information, and the longer male stem helps with higher placement in the ear.
