Abstract: Health status, feed conversion ratio, and mortality are long known broiler chicken production indicators. However, further parameters are required by today's demanding meat markets, as these indicators are not sufficiently accurate to determine flock overall welfare. Morphological asymmetry has been pointed as an alternative welfare indicator as it reflects the ability of the bird to cope with the challenges that rearing conditions may impose. This study aimed at evaluating the possibility of using morphologic… Show more

“…Pressure sensors have also been used to assess walking ability of humans and animals. Nääs et al (2008) conducted a research study that aimed at evaluating broiler locomotion ability, analyzing the peaks of pressures in the legs during walking. A chamber with transparent acrylic walls and an entrance ramp, a horizontal plateau in the middle and an exit ramp, was built.…”

“…Image technologies have been used to evaluate broiler behaviour under different light intensities [29], under different thermal conditions [27,30], under distinct stocking densities [31,32], under different gait scores [33], and during their slaughter [34,35]. Additionally, digital video recording was used to help the development of methods and algorithms to detect lameness in broiler chickens [36][37][38][39][40][41][42] and to analyse behaviour of isolated chicks [43]. It was also used to assess short-term feeding behaviours [44] and to analyse possible changes in behaviour of animals using a tag to monitor their movement [45].…”

“…This IT was identified in three papers (5.3% of total publications). The force-measurement platform was part of the IT that aimed to study the walking ability of broiler chickens [40][41][42]. In a similar way, kinematic technologies, which were present in two publications (3.5% of total publications), were also utilized to study gait abnormalities by producing and analysing 3D images [56] and by utilizing a system that involved the use of a force-measurement platform [42].…”
