Livestock drafting apparatus includes an electronic identification (EID) reader (122) arranged to obtain data from an EID element (121) associated with a livestock animal (120); a drafting controller (126) arranged to receive the obtained data from the EID reader and automatically select a drafting group for the livestock animal based on the obtained data; and an audio output device (134, 140) in communication with the drafting controller to receive an operation instruction which corresponds to the selected drafting group. The audio output device is arranged to output an audible signal which is indicative of the selected drafting group. The drafting controller includes a comparison unit in which predetermined criteria are settable for comparison with the content of corresponding data fields stored for each livestock animal in an animal database that is accessible by the drafting controller, and the drafting controller is arranged to extract the content of a data field for an animal from the database upon receiving the data obtained from the EID element of that animal and to provide the extracted content to the comparison unit,. The comparison unit is arranged to compare the downloaded content with the predetermined criteria to determine the drafting group for the animal.
