Optical flow patterns in broiler chicken flocks as automated measures of behaviour and gait
The aim of this study was to test the hypothesis that valuable on-farm outcome measures of broiler (meat) chicken welfare can be derived from optical flow statistics of flock movements recorded on video or CCTV inside commercial broiler houses. ‘Optical flow’ describes the velocity of imagemotion across an eye or camera and statistical patterns can be derived automatically and continuously thro...
متن کاملMonitoring chicken flock behaviour provides early warning of infection by human pathogen Campylobacter
Campylobacter is the commonest bacterial cause of gastrointestinal infection in humans, and chicken meat is the major source of infection throughout the world. Strict and expensive on-farm biosecurity measures have been largely unsuccessful in controlling infection and are hampered by the time needed to analyse faecal samples, with the result that Campylobacter status is often known only after ...
متن کاملPrediction of welfare outcomes for broiler chickens using Bayesian regression on continuous optical flow data.
Currently, assessment of broiler (meat) chicken welfare relies largely on labour-intensive or post-mortem measures of welfare. We here describe a method for continuously and robustly monitoring the welfare of living birds while husbandry changes are still possible. We detail the application of Bayesian modelling to motion data derived from the output of cameras placed in commercial broiler hous...
متن کاملEarly warning of footpad dermatitis and hockburn in broiler chicken flocks using optical flow, bodyweight and water consumption.
Footpad dermatitis and hockburn are serious welfare and economic issues for the production of broiler (meat) chickens. The authors here describe the use of an inexpensive camera system that monitors the movements of broiler flocks throughout their lives and suggest that it is possible to predict, even in young birds, the cross-sectional prevalence at slaughter of footpad dermatitis and hockburn...
متن کاملRanging Behaviour of Commercial Free-Range Broiler Chickens 2: Individual Variation
Little is known about broiler chicken ranging behaviour. Previous studies have monitored ranging behaviour at flock level but whether individual ranging behaviour varies within a flock is unknown. Using Radio Frequency Identification technology, we tracked 1200 individual ROSS 308 broiler chickens across four mixed sex flocks in two seasons on one commercial farm. Ranging behaviour was tracked ...
