Brantsæter, M., Tahamtani, F. M., Nordgreen, J. et al. 2017. Access to litter during rearing and environmental enrichment during production reduce fearfulness in adult laying hens. Applied Animal Behaviour Science 189, 49-56.

Exaggerated fear-reactions are associated with injurious flying, smothering, feather pecking and other events that compromise animal welfare in laying hens. The aim of this study was to test the hypothesis that chicks with access to...

Jung, L., Knierim, U. 2018. 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...

Sirovnik, J., Würbel, H., Toscano, M. J. 2018. Feeder space affects access to the feeder, aggression, and feed conversion in laying hens in an aviary system. Applied Animal Behaviour Science 198, 75-82.

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

Liu, K., Xin, H. 2017. Effects of horizontal distance between perches on perching behaviors of Lohmann Hens. Applied Animal Behaviour Science 194, 54-61.

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...

Liu, K., Xin, H., Shepherd, T. et al. 2018. Perch-shape preference and perching behaviors of young laying hens. Applied Animal Behaviour Science 203, 34-41.

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...

Sirovnik, J., Stratmann, A., Gebhardt-Henrich, S. G. et al. 2018. Feeding from perches in an aviary system reduces aggression and mortality in laying hens. Applied Animal Behaviour Science 202, 53-62.

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...

Hunniford, M. E., Mason, G. J., Widowski, T. M. 2018. Laying hens’ preferences for nest surface type are affected by enclosure. Applied Animal Behaviour Science 201, 7-14.

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...

Hunniford, M. E., Widowski, T. M. 2018. Curtained nests facilitate settled nesting behaviour of laying hens in furnished cages. Applied Animal Behaviour Science 202, 39-45.

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...

Krause, E. T., Ruploh, T. 2016. Captive domesticated zebra finches (Taeniopygia guttata) have increased plasma corticosterone concentrations in the absence of bathing water. Applied Animal Behaviour Science 182, 80-85.

Keeping animals in captivity should always favour conditions that aim to improve their welfare with respect to species-specific requirements. For laboratory animals, the majority of welfare issues have been explored in rodents thus far, whereas...

Williams, I., Hoppitt, W., Grant, R. 2017. 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...
