A method to improve the housing of breeding rats used to produce pups for tissue (2025)

Rats are considered highly social animals. In the wild, they live in groups and develop complex social structures. Regrouping rats is considered stressful. We therefore wanted to keep animals in monogamous pairs so that they could develop a social bond...

The effects of handling on mouse behavior: cupped hands versus familiar or novel huts or tunnels (2025)

Mice are commonly tail-handled, despite evidence that this is aversive. Alternatives include cupping and tunnel handling; both methods are associated with improved welfare outcomes, including reduced anxiety and improved ease of handling, but tail handling may be perceived as more...

Understanding and mitigating male mouse aggression

We formed a global working group to identify the triggers of aggression e.g. behaviours seen prior to fighting occurring and have identified strategies to mitigate these triggers. We have also identified the signs of a harmonious cage, how to identify...

Long term ear and saphenous cannulation to perform blood sampling over longer periods using the Seldinger technique (2024)

The standard practice to collect a blood sample from a Minipig is to invert the animal onto its back and into a cradle. The blood sample is then collected via jugular venepuncture. This technique can cause large amounts of stress...

Advancing zebrafish husbandry: takeaways from the 2024 husbandry workshop and husbandry summit (2024)

The 2024 Zebrafish Husbandry Workshop and Summit held during the World Aquaculture Society Meeting in San Antonio focused on key areas for improving zebrafish husbandry research. Discussions highlighted the need for comprehensive literature on husbandry, better communication and collaboration between...

A systematic review of the effects of musical enrichment on captive mammals (2025)

Forty two studies examining physiological, behavioural and cognitive mammalian responses to music were identified, with 38.1% of those studies focusing on primates. The studies identified included 23 mammalian species across six animal orders (Artiodactyla, Carnivora, Perissodactyla, Primates, Proboscidea and Rodentia)....

Pup recruitment in a eusocial mammal—Which factors influence early pup survival in naked mole-rats?

In eusocial insects, offspring survival strongly depends on the quality and quantity of non-breeders. In contrast, the influence of social factors on offspring survival is more variable in cooperatively breeding mammals since maternal traits also play an important role. This...

Psychosocial stress, glucocorticoids, and structural alterations in the tree shrew hippocampus

Animal models for chronic stress represent an indispensable preclinical approach to human pathology since clinical data point to a major role of psychological stress experiences, acute and/or chronic, to the development of behavioral and physiological disturbances. Chronic emotional arousal is...

Long term impacts of early social environment on chimpanzee white matter

Early adverse rearing conditions are known to have deleterious consequences on social behavior, cognition, and brain development of both human and nonhuman primates. We analyzed archival diffusion tensor imaging (DTI) data from mother- (MR) or nursery-reared (NR) chimpanzees and used...

Social stress in tree shrews: Effects on physiology, brain function, and behavior of subordinate individuals

Social stress is known to be involved in the etiology of central nervous disorders such as depression. In recent years, animal models have been developed that use chronic stress to induce neuroendocrine and central nervous changes that might be similar...
