Feather pecking and cannibalism in non-beak-trimmed laying hen flocks—Farmers’ perspectives

Pecking-related problems are common in intensive egg production, diminishing hen welfare and production performance, and negatively affecting sustainability. Beak trimming is a common practice to control these problems, but in Finland beak trimming is prohibited. Finnish egg producers have decades-long...

Cause and prevention of injurious pecking in chickens

This collection features three peer-reviewed literature reviews on feather-pecking in poultry. The first chapter describes the three main forms of injurious pecking (IP) in poultry: tissue pecking (TP), aggressive pecking (AP) and feather-pecking (FP). It discusses the origin of severe...

Relationships between beak condition, preening behavior and ectoparasite infestation levels in laying hens

The effects of beak condition on ectoparasite populations and preening in laying hens were investigated. Beak-trimmed and beak-intact caged Hy-Line W-36 hens were infested with either chicken body lice or northern fowl mites using a 2 × 2 factorial design...

Beak trimming reduces feeding efficiency of hens

The ability of beak-trimmed and intact laying hens to ingest feed pellets was examined by highspeed video filming of feeding birds. The birds were exposed to either a deep layer of pellets or a single layer of pellets. In the...

Neurobiological basis of sensory perception: welfare implications of beak trimming

The practice of beak trimming in the poultry industry occurs to prevent excessive body pecking, cannibalism, and to avoid feed wastage. To assess the welfare implications of the procedure, an emphasis of this paper has been placed on the anatomical...

Infrared beak treatment method compared with conventional hot-blade trimming in laying hens

Infrared lasers have been widely used for noninvasive surgical applications in human medicine, and their results are reliable, predictable, and reproducible. Infrared lasers have recently been designed for the express purpose of providing a less painful, more precise beak-trimming method...

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...
