An HSUS Report: Welfare Issues with Furnished Cages for Egg-Laying Hens
Furnished cages were developed in response to criticisms about conventional battery-cage confinement of laying hens in commercial egg production. Battery cages—small, barren, wire enclosures—restrictively confine the birds, depriving them of the opportunity to display many important patterns of behavior. In contrast, furnished cages are typically equipped with a nest box, perch, and dustbathing...
متن کاملLathyrus cicera as quality feed for laying hens
Introduction Research at CLIMA has indicated that Lathyrus cicera and L. sativus (grasspea) have potential as grain legumes on 100 000 to 300 000 ha of neutral to alkaline soils in low-to-medium rainfall areas of southern Australia. They do not have serious disease problems and are envisaged as low maintenance/low cost crops for the purposes of green manure, managing herbicide resistant weeds, ...
متن کاملCage hygiene, laying location, and egg quality: the effects of linings and litter provision in furnished cages for laying hens.
This study investigates the influence of litter provision and linings used for nests and pecking and scratching areas on cage hygiene, laying location, and egg quality. Research was carried out in furnished cages, each housing 60 beak-trimmed ISA Brown hens. Four different treatments were compared in a factorial arrangement, including 2 different nest linings (artificial turf vs. plastic mesh),...
متن کاملTracking individual laying hens in group housing
Many animal species live in social groups and show complex social behaviour. Social behaviour has been well studied on various levels, ranging from classical ethological approaches, i.e. behavioural observations, to experimental and evolutionary approaches focussing on the fitness value of group living. Yet while research on smaller groups has provided important insights into behavioural mechan...
متن کاملThe European Union ban on conventional cages for laying hens: history and prospects.
Since the publication of Animal Machines (Harrison, 1964), there has been widespread public pressure in Europe--supported by European institutions--to "ban the battery cage." The European Union (EU) and national governments (particularly in Northern Europe) funded research on noncage systems for egg production and enriched cages. In 1986, the EU passed a Directive specifying a minimum size for ...
