Barrett, L. A., Blache, D. 2019. Development of a behavioural demand method for use with Pekin ducks. Applied Animal Behaviour Science 214, 42-49.

Behavioural demand tests are informative tools for studying animal welfare, because they asses the motivation of an animal to obtain a given resource. Pekin ducks are a species on which behavioural demand testing has not...

Fuller, G., Heintz, M. R., Allard, S. 2019. Validation and welfare assessment of flipper-mounted time-depth recorders for monitoring penguins in zoos and aquariums. Applied Animal Behaviour Science 212, 114-122.

The time that penguins devote to aquatic behaviors likely has important implications for their welfare in zoos and aquariums. For decades, field researchers have used time-depth recorders (TDRs) to understand the behavior of penguins at...

Muri, K., Stubsjøen, S. M., Vasdal, G. et al. 2019. Associations between qualitative behaviour assessments and measures of leg health, fear and mortality in Norwegian broiler chicken flocks. Applied Animal Behaviour Science 211, 47-53.

Qualitative behavioural assessments (QBA) is an animal-based welfare measure that has been included in several on-farm welfare assessment protocols, including the Welfare Quality® (WQ) protocol for poultry. However, there is a scarcity of information about...

Moroki, Y. 2019. Sham dustbathing in cages by subordinate hens is increased by a partition providing isolation. Applied Animal Behaviour Science 210, 68-72.

Subordinate hens express less sham dustbathing in cages than higher ranked hens, their bouts often being disturbed by a higher ranked hen. However, seeing conspecifics seems to encourage this behaviour by hens. So to avoid...

Baxter, M., O’Connell, N. E. 2019. Does grouping environmental enrichments together affect the way they are used by commercially housed broiler chickens? Applied Animal Behaviour Science 210, 52-59.

Identifying the most attractive ways of presenting environmental enrichments in commercial broiler housing may encourage use and optimise their effectiveness. This study investigated the effect of grouping straw bales (SB), oat hulls (OH; as a...

James, C., Asher, L., Herborn, K. et al. 2018. The effect of supplementary ultraviolet wavelengths on broiler chicken welfare indicators. Applied Animal Behaviour Science 209, 55-64.

Qualities of the light environment are important for good welfare in a number of species. In chickens, UVA light is visible and may facilitate flock interactions. UVB wavelengths promote endogenous vitamin D synthesis, which could...

Norman, K. I., Weeks, C. A., Pettersson, I. C. et al. 2018. The effect of experience of ramps at rear on the subsequent ability of layer pullets to negotiate a ramp transition. Applied Animal Behaviour Science 208, 92-99.

In commercial situations, laying hens must negotiate levels to reach resources such as food, water and litter. Providing ramps in aviary systems reduces collisions and resultant keel bone fractures in adults. We investigated whether providing...

Paul, E. S., Edgar, J. L., Caplen, G. et al. 2018. Examining affective structure in chickens: valence, intensity, persistence and generalization measured using a Conditioned Place Preference Test. Applied Animal Behaviour Science 207, 39-48.

When measuring animals’ valenced behavioural responses to stimuli, the Conditioned Place Preference (CPP) test goes a step further than many approach-based and avoidance-based tests by establishing whether a learned preference for, or aversion to, the...

Tahamtani, F. M., Pedersen, I. J., Toinon, C. et al. 2018. Effects of environmental complexity on fearfulness and learning ability in fast growing broiler chickens. Applied Animal Behaviour Science 207, 49-56.

Increasing environmental complexity, i.e. by providing environmental enrichment, has been suggested as a way to improve broiler chicken welfare. One issue affecting broiler welfare is the level of fearfulness of the flock. Exaggerated fear responses...

Perkovic, K., Mettke-Hofmann, C. 2018. Colour polymorphic Gouldian finches avoid complex backgrounds but prefer simple camouflage colours over white backgrounds. Applied Animal Behaviour Science, 206, 102-108.

Many animals blend in well with their environment known as camouflage which is a successful predator avoidance strategy. However, captive environments often do not allow for camouflage and may result in stress and reduced welfare...
