Animal ethicists have recently debated the ethical questions raised by disenhancing animals to improve their welfare. Here, we focus on the particular case of breeding blind hens for commercial egg-laying systems, in order to benefit their welfare. M

Automatic detection of deviations in activity levels in groups of broiler chickens – A pilot study

Autor: Cécile Cornou, H. H. Kristensen

Publikováno v: Biosystems Engineering. 109:369-376

Automatic monitoring of activity levels in broiler chicken flocks may allow early detection of irregular activity patterns, indicating potential problems in the flock. Leg disorders are the main welfare concern for modern broiler chickens. Dynamic co

This paper reviews the development of precision livestock farming (PLF), from the view point of the engineer, the farm animal and the farmer; PLF is the principal means by which 'smart' sensors will be used in livestock farming. It considers the tech

The development of behaviour in a line of chickens that are born sighted ( rdd ) but turn blind after hatching was compared with a line that is blind at hatch ( beg ) and with sighted White Leghorn controls (WL) to test the hypothesis that birds that

Publikováno v: Journal of Applied Poultry Research. 10:172-177

SUMMARY The depopulation of laying hens is recognized as a serious welfare problem in the poultry industry. In the UK, the current methods for depopulating these spent hens exert several stressors on the birds as well as on the catching personnel. Si
