yes they want to tag goats, I have been studying this for awhile now. Yahoo has a group GoatID that will give you a lot of information. Right now you just have to follow state regs. Freepmail me privately if you want I have lots of links and info.
Goats can be a good source of food. High protein milk and even meat.
When the "free" trade undermines US agriculture and prices of food go up, the tags will help to suppress underground food production.
