WP 1.2, 1.3:

A newly
developed automated, image-based recording system of the animal welfare
indicator 'keel bone status' at the slaughterhouse has been validated with more
than 2000 laying hens and is ready for application. In order to test whether
slaughterhouse recordings reflect the farm situation, the prevalence of keel
bone damage was recorded in 20 flocks before catching, after capture and
transport at the slaughterhouse and at the slaughter chain. No damage was found
that was caused by capture and transport. The automated recording leads to a
slight underestimation of the prevalence. The system offers the possibility to
record the keel bone status in many flocks over long periods of time in a
comparable way with little time expenditure and to give feedback to the laying
hen farmers. The development of a recording system for skin injuries, on the
other hand, was not feasible under practical conditions at the slaughter chain.
Two approaches were pursued for a possible early warning system for cannibalism
in turkeys: Metal balls equipped with a microphone were developed which can
reliably detect pecking frequencies in the barn using a CNN model. Using
optical flow, changes in general activity were automatically recorded. Both
methods are largely validated and ready for use. So far, correlations with the
occurrence of cannibalism have not been found; however, this requires further

cooperation with CLK GmbH, being responsible for the technical side of the
project, and the University of Veterinary Medicine Hannover, (project coordination), University of Munich München, Univerity of Applied Sciences Osnabrück, Barnstorfer Geflügelschlachterei and Heidemark GmbH
