Pain issues in poultry

This review highlights the possible pain experienced by layer and broiler poultry in modern husbandry conditions. Receptors which respond to noxous stimulation (nociceptors) have been identified and physiologically characterised in many different part of the body of the chicken including...

Current methods and techniques of beak trimming laying hens, welfare issues and alternative approaches

Current methods and techniques of beak trimming laying hens, welfare issues and alternative approaches Beak trimming is used in the egg industry to prevent mortality from cannibalism and minimise injurious pecking, vent pecking, aggressive pecking at the head and all...

Feather pecking and cannibalism

This well attended Workshop stimulated lively discussion that continued throughout the Conference. It addressed a behavioural problem in laying fowl that causes concern from both welfare and economic standpoints, particular in the context of the current trend towards alternative colony...

The prevention and control of feather pecking in laying hens: identifying the underlying principles

The prevention and control of feather pecking in laying hens: Identifying the underlying principles Feather pecking (FP) in laying hens remains an important economic and welfare issue. This paper reviews the literature on causes of FP in laying hens. With...

Effects of feeding corticosterone and housing conditions on feather pecking in laying hens (Gallus gallus domesticus)

Effects of feeding corticosterone and housing conditions on feather pecking in laying hens (Gallus gallus domesticus) Feather pecking (FP) and cannibalism in laying hens are disadvantageous to the well-being of the birds. We investigated whether stress could be proposed as...

Comparison of changes in the plumage and body condition, egg production, and mortality of different non-beak-trimmed pure line laying hens during the egg-laying period

The spread of both alternative and non-cage laying hen housing systems and the more forceful European refusal of beak trimming generate new problems in commercial egg production. The hybrid layers, which have been genetically selected under cage housing conditions for...

Welfare consequences of omitting beak trimming in barn layers

Beak trimming is used worldwide as a method of reducing the damage to feathers and skin caused by injurious pecking in laying hens. However, beak trimming also causes some welfare issues as trimming the beak results in pain and sensory...

A persistent abnormal repetitive behaviour in a false water cobra (Hydrodynastes gigas)

Stereotypies (a subset of Abnormal Repetitive Behaviour [ARB]) are characterised by an unchanging pattern of behaviour and in captive animals can be associated with poor welfare. Although well known in certain taxa, little is known about both welfare and ARBs...

A review of research in primate sanctuaries

While non-human primate studies have long been conducted in laboratories, and more recently at zoological parks, sanctuaries are increasingly considered a viable setting for research. Accredited sanctuaries in non-range countries house thousands of primates formerly used as subjects of medical...
