Behavioural and physiological responses of laying hens to automated monitoring equipment

Automated monitoring of behaviour can offer a wealth of information in circumstances where observing behaviour is difficult or time consuming. However, this often requires attaching monitoring devices to the animal which can alter behaviour, potentially invalidating any data collected. Birds...

Feeder space affects access to the feeder, aggression, and feed conversion in laying hens in an aviary system

In laying hens, minimal requirements for feeder space (cm per bird) are based primarily on data from small groups of hens (n

Are practice recommendations for the prevention of feather pecking in laying hens in non-cage systems in line with the results of experimental and epidemiological studies?

Feather pecking (FP) in laying hens is an important animal welfare problem in practice, despite extensive research and increasing sources of advice for farmers. We aimed to give an overview over results from experimental and epidemiological studies. We included non-cage...

Curtained nests facilitate settled nesting behaviour of laying hens in furnished cages

Egg location can be used to determine the nests that hens prefer, but it does not indicate whether the design of that nest satisfies a hen's nesting motivation. Hens that are satisfied with the nest resources exhibit characteristic settled nesting...

Laying hens’ preferences for nest surface type are affected by enclosure

The nest surfaces preferred by hens are inconsistent with those typically provided in commercial settings. However, little research has explored hens' preferences for commercially available nest surfaces. Our objective was to compare hens' preferences for two such surfaces – red...

Feeding from perches in an aviary system reduces aggression and mortality in laying hens

Some commercial aviary systems for laying hens allow birds to access feed by standing on perches instead of platforms. Despite reports that providing laying hens with perches relates to reduced aggression and cannibalism, and increased prevalence of keel bone damage,...

Perch-shape preference and perching behaviors of young laying hens

Provision of perches in enriched colony or cage-free hen housing facilitates birds' ability to express natural behaviors, thus enhancing animal welfare. Although considerable research has been conducted on poultry perches, further investigation is needed of perching behavior and preference of...

Effects of horizontal distance between perches on perching behaviors of Lohmann Hens

Perching is a highly-motivated natural behavior of laying hens that has been considered as one of the essential welfare requirements. The objective of the study was to evaluate perching behaviors of laying hens as affected by horizontal distance (HD) between...

Abnormal repetitive behaviours in captive birds: A Tinbergian review

Abnormal repetitive behaviours (ARBs) are associated with past, or present, welfare problems and are common elements of the behavioural repertoire of some captive animals, including birds. Millions of birds from hundreds of species are held in various captive settings, yet...

Effect of litter material and stocking density on bone and tendon strength, and productive performance in broilers

Litter material and stocking density were evaluated on welfare-related variables and productive performance in broilers. Male chicks (n = 744, “Ross 308” strain) were raised on either tezontle (TEZ) or wood shavings (WS) litter, with a stocking density of either...
