For traceability, many animals have to be identified as they enter the market or lairage, or as they leave the farm. Where individual identification requires manual handling of the animal, this should be done by trained staff. Restraining facilities should be used effectively and quietly so as not to stress the animals.
Sufficient lighting will be necessary for identification, but this should not be in the eye-line of the animals as it may deter them from entering the restrainer.
