From 2012 onwards, housing of laying hens in conventional battery cages will be forbidden in the European Union and only …
1. The welfare of hens in 26 flocks (6 conventional cage, 6 furnished cage, 7 barn, 7 free range) was assessed throughout the laying period using a combination of data on physical health, physiology and injurious pecking, collected by researchers on farm and during post-mortem analysis, and information submitted by producers. 2. There was an …
Feather pecking is a major welfare problem in egg production. It may be caused by endogenous (genetic and physiological) and environmental (feeding, density and housing conditions) factors. Despite the number and variety of experiments performed over past years, it is still not possible to define a genetic background for this trait. A possible reason is …
Feather pecking (FP) remains a major welfare and economic problem in laying hens. FP has been found to be related to other behavioural characteristics, such as fearfulness. There are indications that fearful birds are more likely to develop FP. Furthermore, FP can lead to increased fearfulness in the victims. To investigate further the relationship between …
Recent studies showed that laying hens learn not to peck at bitter-tasting feathers from conspecifics. In the present experiment, feathers of newly hatched chicks were made distasteful by spraying them with a bitter-tasting substance (quinine). It was hypothesized that chicks could detect quinine and learn to avoid the downy feathers and the feathers of conspecifics …
1. Feather pecking is one of the major problems facing the egg industry in non-cage systems and is set to become even more of an issue with the European Union ban on the keeping of laying hens in barren battery cages which comes into force in 2012 and the prospect of a ban on beaktrimming. …
In the present study, the application of life cycle assessment (LCA) for the comparison of two egg packages, from polystyrene …
Despite significant recent public concern and media attention to the environmental impacts of food, few studies in the United States …
Livestock production has a major impact on the environment. Choosing a more environmentally-friendly livestock product in a diet can mitigate …
There has never been a greater need for delivering timely and policy-relevant information on the magnitude and evolution of the …
As part of a systemic assessment toward social sustainability of egg production, we have reviewed current knowledge about the environmental …

Ergosterol (ERG) content, being an indicator of fungal biomass, was analyzed in samples of eggshell, egg white, and egg yolk …
A move from conventional cages to either an enriched cage or a noncage system may affect the safety or quality, …
Commercial egg laying farms are under intense pressure to eliminate the practice of beak trimming due to the potential for acute and chronic pain to the trimmed birds. However, elimination of beak trimming may have severe implications for animal welfare, as pecking between untrimmed birds can result in body damage that can ultimately lead to …
