Hot-iron branding causes acute and prolonged pain in cattle and is performed without anesthesia in most countries. Alternative identification methods including RFID tags and electronic ear tags provide equivalent traceability with less welfare harm.
Hot-iron branding is a clear example of a welfare harm perpetuated by tradition despite available alternatives. The procedure causes documented acute pain, tissue destruction, and prolonged healing discomfort. No analgesic is used in most commercial contexts. The practical purpose — permanent individual identification — is achieved equivalently by electronic ear tags, RFID transponders, and retinal or facial recognition systems that are now cost-competitive with traditional branding. The persistence of hot-iron branding in jurisdictions that have not banned it reflects inertia rather than operational necessity. Transitioning to electronic identification improves individual animal traceability while eliminating an unnecessary welfare harm.
