When cattle, bison or buffalo go to an abattoir, you must report the off movement from your holding.
When you send animals to slaughter at a licensed abattoir, you must tell the British Cattle Movement Service (BCMS) about their movement off your holding. BCMS must receive the information within 3 days of the date of movement.
In Scotland the abattoir will report the off farm movement on your behalf; abattoirs in England and Wales may also report this off movement on your behalf. However, as the keeper you are still responsible for making sure BCMS has received the information within the deadlines for movement reporting.
