			===== Organisation of the test =====
	Ideally at birth the basic non-variant data on the animal such as farm ID, animal ID, birth date, birth location, sex, calving ease score will have been stored in the central database. When the animal is slaughtered, the hot carcass weight and the carcass grade are determined and stored in the database of the abattoir. The slaughter data should be sent to the animal recording organisation at regular intervals. The link between slaughter records and the standing or non-variant data of the animal is provided by the animal’s ID number.
