The USDA’s proposed National Animal Identification System (NAIS) was originally designed to give the big beef producers help in getting export markets which required disease controls. The idea is that every single livestock animal in the United States will be identified and tagged. All livestock animal movements will be tracked, logged and reported to the government. The benefit is to the big factory farms who probably do need this type of regulation. They get to do single ID’s for large groups of animals. Small farmers, pet owners and homesteaders will have to tag and track every single animal.
