Environmental Enrichment

Opportunities for refinement of non-human primate vaccine studies

Non-human primates (NHPs) are used extensively in the development of vaccines and therapeutics for human disease. High standards in the design, conduct, and reporting of NHP vaccine studies are crucial for maximizing their scientific value and translation, and for making...

Environmental enrichment increases aquatic animal welfare: A systematic review and meta-analysis

With the rapid development of aquaculture and the gradual decrease in fishery resources, aquatic animal welfare (AAW) has received increasing attention from animal protection organisations, government departments, biologists, fish culturists and consumers. Although environmental enrichment (EE) can potentially benefit AAW,...

Effects of pen partition design and hiding facilities on elimination and lying behavior of finishing pigs

In intensive commercial pig production systems, the spatial distribution of elimination and lying behaviors plays a crucial role in pen hygiene, management efficiency, and animal welfare. Pen partition design and the provision of hiding facilities are key structural factors that...

Pardon my finch … have you seen my juicy garland?

We have a responsibility to promote a Culture of Care to ensure that all species have an appropriate positive environment. Enrichment provides holistic welfare opportunities for captive animals enabling them to demonstrate their natural behaviour. Commercially available enrichment is usually...

Ethological constraints and welfare-related bias in laboratory mice: Implications of housing, lighting, and social environment

Laboratory mice are the most widely used model organisms in biomedical and behavioral research, yet growing concerns regarding reproducibility and translational validity have highlighted the substantial influence of housing and husbandry conditions on experimental outcomes. Although domestication is often assumed...

Validation of enhanced floor pen housing for chickens

This study assesses the transition from isolator housing to an enhanced floor pen system for chickens, with the goal of improving Animal Welfare and promoting natural behaviours. Historically, chickens in our facility were housed in isolators, which limited the opportunities...

Assessment of behavioral, clinical, and histological outcomes in Sprague-Dawley rats housed in enriched colony cages versus conventional pair housing over 28 days

The standardization of husbandry in animal studies for drug development aims to minimize variability and enhance inter-laboratory comparability. Rats are a commonly used species in such studies. This standardization yields housing conditions that do not reflect the natural environment of...

Alpaca (Vicugna pacos) husbandry and their welfare

A key diagnostic tool in breeding practice is systematic observation: by identifying abnormalities in natural behaviour, it can highlight early signs of reduced welfare or physical and mental health issues in livestock and other animals. The aim of this paper...
