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...

The effect of auditory enrichment, rearing method and social environment on the behavior of zoo-housed psittacines (Aves: Psittaciformes); implications for welfare

The psychological and physiological effects of different genres of music are well documented in humans. These concepts have also been studied in kenneled dogs and some exotic animals, implying that animals may experience benefits similar to those of humans. This...

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...

The effect providing space in excess of standards on the behaviour of budgerigars in aviaries

Budgerigars housed in conventional cages have no opportunity for some normal behaviours, in particular flight, and develop stereotyped behaviours. Increasingly aviaries are used for groups of budgerigars but the minimum space requirement to support normal behaviour is not known. We...

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...

You know what? I’m happy

Recent studies suggest that cognitive bias could constitute a novel and valid measure of animal welfare. Although interest for a link between personality and cognition is growing, no study to date investigated whether a cognitive bias might be related to...

Providing laying hens in group-housed enriched cages with access to barley silage reduces aggressive and feather-pecking behaviour

Two trials were conducted to study the effect of feeding barley silage on the behaviour and performance of beak-trimmed laying hens. In each trial, 20 hens and 2 roosters were housed in each of eight group-housed enriched cages, with four...

Effects of mate separation in female and social isolation in male free-living Greylag geese on behavioural and physiological measures

The presence of a social partner may significantly contribute to coping with stressful events, whereas dyadic separation generally increases glucocorticoid levels and, thereby, might also affect immune function and health. To study the covariation between social factors, immuno-reactive corticosterone metabolites,...
