Conventional cage housing for laying hens evolved as a cost-effective egg production system. Complying with mandated hen housing alternatives would raise marginal production costs and require sizable capital investment. California data indicate that shifts from conventional cages to barn housing would likely cause farm-level cost increases of about 40% per dozen. The US data on …
Resting on perches is an important behaviour for laying hens. However, perches in laying hen husbandry systems are associated with health problems which may result from inadequate perch designs. The aim of this study was to focus on particular behavioural patterns shown by laying hens on different perches during night-time in order to test whether …
By investigating the prevalence and antimicrobial resistance characteristics of Gram-positive bacteria from organic and conventional keeping systems of laying hens, …
Organic livestock production is a means of food production with a large number of rules directed towards a high status …
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 …
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. …
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, …
This paper examines the challenges that climate change raises for animal agriculture and discusses the contributions that may come from …
Organic agriculture addresses the public demand to diminish environmental pollution of agricultural production. Until now, however, only few studies tried …
The provision for dustbathing material will be a legal requirement in cage-housing systems for laying hens within the European Union beginning in 2012. At present, food particles are widely used and typically offered in small amounts on Astroturf mats one or more times per day to facilitate dustbathing, pecking, and scratching. In the present study, …
Farm-level factors that could be associated with feather pecking of layers kept in organic farming systems were monitored in 63 flocks from 26 farms located in different areas of The Netherlands. Data on housing and management practices were collected and plumage damage as a measure of feather pecking was scored at 50 weeks of age …
In this study, laying hen welfare is taken into account as part of an overall ‘egg safety and quality concept’. A holistic approach is adopted that encompasses the whole food chain in which responsibility for the production of safe and high quality eggs is shared along the entire food chain. Scientific data on egg quality …
