A “Colorado Approved Feedlot” is a confined feedlot area approved and recorded by the State Veterinarian or his or her authorized agent.
The approved feedlot shall be maintained for growing and/or finish-feeding of animals in dry lot with no provisions for pasturing or grazing. Animals leaving such a feedlot must move directly to slaughter or to another Colorado Approved Feedlot and must be accompanied by a current brand inspection certificate where and when applicable.
