Abstract: An antenna system for use in processing of livestock carcasses including in combination, antenna means adapted to transmit and receive signals from transponders in or on carcasses moving on a conveyer system, support means adapted to support the antenna, pivoting means adapted to enable the antenna to pivot on the support means as each carcass comes into contact with the antenna, wherein in operation, the pivoting action enables a wiping contact to be maintained between the antenna and a carcass sufficient to obtain a positive reading of the transponder irrespective of a rotational and/or angular displacement of the carcass about a vertical axis without causing dislodgement of the carcass from the conveyer system or bruising of the carcass.

Abstract: An identification apparatus for animals or carcasses carrying electronic identification devices, (EID) (2) moving past an antenna (10). The identification apparatus including motion sensing means (12, 13, 14, 17) and marking means (16) adapted mark the animals or carcasses according to whether EID (2) is present, absent or non-functioning, whereby the animals' carcasses can be identified, drafted or sorted according to marking supplied.
