Boredom is an emotional state that occurs when an individual has nothing to do, is not interested in the surrounding, and feels dreary and in a monotony. While this condition is usually defined for humans...

Ojelade, O. C., Durosaro, S. O., Akinde, A. O. et al. 2022. Environmental enrichment improves the growth rate, behavioral and physiological response of juveniles of Clarias gariepinus under laboratory conditions. Frontiers in

Environmental enrichment (EE) improves the growth rate and welfare of some cultured fishes. However, most cultured fish species are raised in non-enriched housing conditions. Clarias gariepinus is an important commercial fish species, but little is...

Aldhshan, M. S., Mizuno, T. M. 2022. Effect of environmental enrichment on aggression and the expression of brain-derived neurotrophic factor transcript variants in group-housed male mice. Behavioural Brain Research 433, 113986.

Social and environmental factors influence behavior via modulation of brain physiological functions. Environmental enrichment (EE) is an animal housing technique that provides complex sensory, motor, and social stimulation, leading to modifications in the innate aggressiveness...

Guérineau, C., Lõoke, M., Ganassin, G. et al. 2022. Enrichment with classical music enhances affiliative behaviours in bottlenose dolphin. Applied Animal Behaviour Science 254, 105696.

Environmental enrichment is a crucial element for the promotion of welfare of animals kept under human care. While a large variety of environmental enrichments has been proposed and studied for terrestrial animals, including a growing...

Vasdal, G., Gebhardt-Henrich, S. G., Tahamtani, F. et al. 2022. Perch use in commercial broiler breeders – Preference for perch material and effect of age. Applied Animal Behaviour Science 253, 105680.

Unlike for laying hens in most European countries, few broiler breeders have access to perches, and there is a need for more knowledge on perching behavior in broiler breeders. The aim of this study was...

Kriengwatana, B. P., Mott, R., ten Cate, C. 2022. Music for animal welfare: A critical review & conceptual framework. Applied Animal Behaviour Science 251, 105641.

Music can have powerful effects on human health and wellbeing. These findings have inspired an emerging field of research that focuses on the potential of music for animal welfare, with most studies investigating whether music...

Lippi, I. C. de C., Caldara, F. R., Almeida-Paz, I. C. de L. et al. 2022. Effects of music therapy on neuroplasticity, welfare, and performance of piglets exposed to music therapy in the intra- and extra-uterine phases. Animals 12(17), 2211.

The rearing environment of pigs can cause a high level of stress due to the lack of stimuli and the impossibility of carrying out natural behaviors. Music therapy is a way to enrich the environment...

Greeson, J. L., Gabriel, K. I., Mulcahy, J. B. et al. 2022. An evaluation of ethograms measuring distinct features of enrichment use by captive chimpanzees (Pan troglodytes). Animals 12(16), 2029.

Environmental enrichment provides mental stimulation and minimizes abnormal behaviors in captive animals. In captive chimpanzees, individual animals may vary in the ways in which they benefit from enrichment or use enrichment devices, so investigating nuances...

Ramankevich, A., Wengerska, K., Rokicka, K. et al. 2022. Environmental enrichment as part of the improvement of the welfare of Japanese quails. Animals 12(15), 1963.

The aim of this study was to evaluate the indicators of the behavioural and physiological welfare of Japanese quails (Coturnix japonica) as possible responses to the enrichment of the birds’ habitat. The study sample consisted...

Maaskant, A., Janssen, I., Wouters, I. M. et al. 2022. Assessment of indoor air quality for group-housed macaques (Macaca spp.). Animals 12(14), 1750.

Indoor Air Quality (IAQ) is strongly associated with animal health and wellbeing. To identify possible problems of the indoor environment of macaques (Macaca spp.), we assessed the IAQ. The temperature (°C), relative humidity (%) and...
