Cooked food for non-human primates: A discussion by the Laboratory Animal Refinement & Enrichment Forum

"Do any of you give cooked food like pasta, potatoes or vegetables to non-human primates? What's your experience? Do the animals benefit from cooked food; do they like it; does it affect their health in any way? Do you add...

Ultrasonic vocalisation as a measure of positive welfare in rats

Studies of animal welfare in laboratory animals have historically relied on the measurement of negative indicators rather than the assessment of positive indicators of welfare. Practical methods of welfare assessment are required to allow refinement of housing and experimental protocols....

Rabbits housed in pens: Do they have an enrichment preference?

Since the antibody production facility at Envigo RMS opened in 2015 we have been offering our rabbits a variety of disposable and non-disposable enrichment in a floor pen arrangement. There is a perception that our rabbits have a preference for...

Social interaction for non-sibling pregnant New Zealand white rabbits on reproductive toxicology

Rabbits are gregarious animals that live in social groups in the wild so individually housing our animals, while meeting the present scientific objectives, restricts their natural social behaviour. How to meet the social needs of our rabbits while maintaining a...

The curious tale of axolotl enrichment

Axolotls can be used in scientific research to provide fertilised embryos for investigations into the genetic pathways controlling stem cell development. Breeding animals are housed for several years and environmental enrichment is required to improve welfare by providing axolotls greater...

Behavioral research as physical enrichment for captive chimpanzees

In this study, we evaluated the potential for a behavioral research study, designed to evaluate chimpanzee decision‐making behavior, to also encourage increased activity in a group of zoo‐housed chimpanzees. For the behavioral study, the chimpanzees had to carry tokens to...

Behavioral responses of three armadillo species (Mammalia: Xenarthra) to an environmental enrichment program in Villavicencio, Colombia

Enrichment is a powerful tool to improve the welfare of animals under human care. Stress‐related health and behavioral problems, as well as reproductive failure, are frequent in armadillos (Xenarthra, Cingulata, Dasypodidae) under human care, which hinders the development of successful...

Improving rabbit enrichment: Developing a rolling enrichment plan

A three-week enrichment preference study trialling different substrates, food and pen structures was carried out in three, group-housed female New Zealand White Rabbits (NZW). Preference results: structural - rabbits spent the most time with a circular table (repurposed empty wooden...

Introduction of gang caging for group housed rats

Using an existing gang cage designed for ferrets, we developed a version that would be suitable for housing rats. Caging consisted of 3 floors with a combined floor area of 11620m, connected by 2 ladders. Each individual unit can be...

Up-regulation of IGF-1 in the frontal cortex of piglets exposed to an environmentally enriched arena

Environmental enrichment (EE) is widely used in the life sciences to study effects of environment on the brain. In pigs, despite lack of EE being a key welfare issue there is little understanding of brain effects of EE in pigs....
