Environmental Enrichment

Early-life environmental enrichment promotes positive animal welfare for juvenile Atlantic salmon (Salmo salar) in aquaculture research (2025)

Early life experiences have long-lasting effects on behaviour and physiology, influencing development of adaptive natural behaviours. Enriching farmed environments encourages expression of natural behaviours in captive fish, promoting positive animal welfare, important for conducting valid and reproducible research and informing...

A guide for junior technicians: The importance of giving the correct amount of nesting in a mouse IVC and the benefits of an enriched cage (2025)

During our experience of working on the breeding floor of the University of Cambridge's Anne McLaren Building, we have recognised the importance of giving the correct amount of nesting and the benefits of additional enrichment.

Dairy calves provided with environmental enrichment are more active, playful and have fewer feeding interruptions (2025)

Concerns for farm animal welfare have led to the use of environmental enrichment to stimulate natural behaviours and promote positive emotions. In cattle, the provision of brushes is sometimes recommended but their use in calves and the effects they may...

The development and use of a cage-topper to enhance rat welfare (2025)

The welfare of rats used in scientific research is an important concern. Recent studies show that larger, more complex housing improves rat welfare compared to standard conventional cages. However there are typically both practical and financial constraints to implementing this....

Behavioural engagement of Holstein Friesian dairy cattle with different mounting techniques for salt licks as environmental enrichment (2025)

With increasing numbers of dairy farms adopting zero-grazing systems, there is a growing need for indoor environmental enrichment methods. Enrichment is necessary to meet industry requirements and fulfil behavioural motivations, such as oral manipulation. This study evaluated the magnitude with...

Physiological effects of environmental enrichment on BALB/c and C57BL/6 strain mice (2025)

Our aim was to assess the effects of enriched environment (EE) on some physiological variables, comparing BALB/c and C57BL/6 strain mice. Female BALB/c and C57BL/6 were individually housed under standard laboratory cages for 6 weeks and randomly separated into groups (n = 7...

Auditory enrichment on facial and physiological responses of Pantaneiro geldings and mares under short-term stress (2025)

This study aimed to evaluate the effect of auditory stimuli on mares and geldings during social isolation and movement restriction, and their ability to promote the reduction of stress responses. The research was conducted with eight Pantaneiro horses, divided into...

Guinea pig (Cavia porcellus) welfare: Associations between husbandry practices, human–animal interactions, and animal behaviour (2025)

Research on the welfare of pet guinea pigs and connections between their behaviour and husbandry practices is scarce. Through an online survey among 1181 German-speaking guinea pig caretakers, we investigated husbandry practices (including social composition, housing type, free roaming, enrichment,...

A metric-based, meta-analytic appraisal of environmental enrichment efficacy in captive primates (2025)

Non-human primates (hereafter ‘primates') constitute a common group of animals in captivity but their captive maintenance involves ethical and husbandry issues, many of which can be addressed through environmental enrichment (hereafter ‘enrichment'). Enrichment is often applied in a trial-and-error fashion...
