Are privacy rights of cattle compromised with RFID replacing brands?

SJMercury News has an article about how the USDA is requiring cattle transported interstate to have RFID tags.

The history of branding is long.

And there of course cattleman protesting the change.

I wonder if the cattle could hire lawyers they can make a claim of their privacy rights being violated now that anyone can read their RFID tags and figure out their history.  Where they born, where they have been, etc.  This is of course silly.

Wouldn't it be great if everything in the data center had a unique ID?
