Environmental Enrichment

Includes structural, behavioral, food, and auditory enrichment.

Figueira, M. P., Silva, F. F. R., Ribeiro, A. et al. 2021. The behavioral response of the crab-eating fox to olfactory enrichment. Applied Animal Behaviour Science 242, 105430.

The effect of olfactory stimuli as a means of environmental enrichment is underexplored in canids. The crab-eating fox is the most abundant wild canid in zoos, but few studies have addressed the reaction of this...

Saraiva, J. L., Nogueirinha, M., Teodósio, R. et al. 2021. The effect of tank cover on welfare of farmed Nile tilapia. Applied Animal Behaviour Science 241, 105396.

Welfare in aquaculture is a pressing topic. One of the main measures to improve the life of farmed fish is implementing environmental enrichment, which can include the addition of structural covers to rearing tanks. Here...

de Jong, I. C., Blaauw, X. E., van der Eijk, J. E. J. et al. 2021. Providing environmental enrichments affects activity and performance, but not leg health in fast- and slower-growing broiler chickens. Applied Animal Behaviour Science 241, 105375.

Effects of environmental enrichment on activity, behaviour, walking ability, contact dermatitis and performance were investigated in fast- and slower-growing broiler chickens. A total of 840 day-old male broilers, 420 of a fast-growing strain (Ross 308)...

Minie, V. A., Petric, R., Ramos-Maciel, S. et al. 2021. Enriched laboratory housing increases sensitivity to social stress in female California mice (Peromyscus californicus). Applied Animal Behaviour Science 241, 105381.

Domesticated mice and rats have shown to be powerful model systems for biomedical research, but there are cases in which the biology of species is a poor match for the hypotheses under study. The California...

Miglioli, A., da Silva Vasconcellos, A. 2021. Can behavioural management improve behaviour and reproduction in captive blue-and-yellow macaws (Ara ararauna)? Applied Animal Behaviour Science 241, 105386.

Environments that do not provide animals with appropriate stimuli may affect their welfare and reproduction, for example by precluding them from exhibiting their full behavioural repertoire. In this study, we sought to evaluate the effectiveness...

Kalies, A., Baumgartner, J., Beyerbach, M. et al. 2021. Interactive rooting towers and behavioural observations as strategies to reduce tail biting on conventional pig fattening farms. Animals 11(11), 3025.

Eight pens (25 pigs/pen; n = 200) provided with an interactive straw-filled rooting tower (experimental group) and five pens (25 pigs/pen; n = 125) with a stationary (fixed) tower without straw (control group) were compared...

Hu, J., Xiong, Y., Gates, R. S. et al. 2021. Perches as cooling devices for reducing heat stress in caged laying hens: A review. Animals 11(11), 3026.

Heat stress is one of the most detrimental environmental challenges affecting the biological process and the related production performance of farm animals, especially in poultry. Commercial laying hens have been bred (selected) for high egg...

Mondin, C., Trestini, S., Trocino, A. et al. 2021. The economics of rabbit farming: A pilot study on the impact of different housing systems. Animals 11(11), 3040.

This research evaluates the economic sustainability of rabbit farms using different housing systems—bicellular (BI), conventional dual-purpose (DP) and enriched cages designed according to the World Rabbit Science Association guidelines (WRSA)—through a field-based study involving six...

Desforges, E. 2021. Challenges and solutions surrounding environmental enrichment for dogs and cats in a scientific environment. Animals 11(10), 2980.

Dogs and cats housed in research-, kennel- and cattery-type settings are reliant on caregivers to optimise their day-to-day experiences and welfare. The goal is to provide enriching environments for physical, social and environmental control; behavioural...

Padrell, M., Amici, F., Córdoba, M. P. et al. 2021. Artificial termite-fishing tasks as enrichment for sanctuary-housed chimpanzees: Behavioral effects and impact on welfare. Animals 11(10), 2941.

Artificial termite-fishing tasks are a common enrichment for captive great apes, promoting species-typical behaviors. Nonetheless, whether these activities are linked to changes in other behaviors and whether these changes persist over time has seldom been...
