The invention relates to an animal body measuring apparatus, designed to individually detect features of slaughtered animal bodies that are conveyable in a row at a distance from each other and along a path, in particular poultry bodies, which measuring apparatus comprises at least one sensor, a measurement passage space for conveying the animal bodies through along a measurement passage path, on which at least one said sensor is arranged, and a holding means. The holding means comprises a movement means, by means of which said sensor, by moving the sensor back and forth, is displaceable between the measurement position lying within the measurement passage space and an outer position permitting free passage of the animal bodies, which outer position as such lies completely outside the measurement passage space. A processing apparatus for removing the meat of slaughtered animal bodies, in particular gutted bodies of poultry whose extremities have been detached, comprises at least one measuring apparatus of the stated design.
