Welfare of laying hens in cages and alternative systems: Environmental, physical and behavioural aspects

There are many different characteristics of housing systems which affect the welfare of laying hens, particularly because welfare itself has many diverse aspects. When cause and effect relationships between systems and welfare are assessed, it is evident that no system...

Effects of perches in laying cages on welfare and production of hens

Caged hens spent 25 to 50% of the light period and around 85% of the dark period roosting on perches. Perches with a rectangular cross-section caused less damage to the feet of birds than those with a circular cross-section.

Environmental enrichment influences on body weight, feathering, food condition and behaviour of caged white leghorn hens

Novel objects, providing a diversity of tactile, visual, and auditory stimuli, hung in front of one row of caged within reach of the caged hens, improved foot and feather conditions. Enriched hens were more confident in a novel environment.

The significance of fowl’s bathing in dust

Dustbathing in fowls (such as chickens) consists of tossing the litter onto and between the fluffed feathers and subsequently enclosing it by flattening the feathers. Recommendations are given concerning adequate dustbathing litter. A chronic deprivation of adequate litter leads to...

Effects of nest linings, pecking strips and partitioning on nest use and behaviour in modified battery cages

Hens spent most time in and made most visits to nest type C [peckable strip of artificial grass attached above the nest rear]. They made most visits to the nest [3 nest sites for 4 hens per cage] when solid...

Effects of environmental enrichment and gentle handling on behaviour and fear responses of transported broilers

Enriched/handled birds were more active in their home pens than control animals. ..The most fearful birds were those which had been enriched [fabric squares, plastic rings, grass, perches, etc.] and handled, whilst the least fearful bird were enriched but not...
