Impact of an implanted intra-abdominal telemetry transmitter on fecal excretion of corticosterone and IgA in adult male F344 and BN rats (Rattus norvegicus)

Telemetry is a widely used method for obtaining physiologic data from rats, but it is uncertain how distressing it is for the animals to live with an implanted transmitter for long periods. The present study aimed to assess this impact...

Elastic motivation for circuit running behaviour in captive African striped mice Rhabdomys dilectus: A consumer demand approach

Captive environments often result in repetitive locomotor behaviours in animals, yet the motivation for these behaviours remains poorly understood. We investigated whether circuit running in African striped mice Rhabdomys dilectus represents a necessary coping mechanism or a flexible, cost-sensitive behaviour,...

Effect of novel high-fat diet feeding methods on food wastage, weight gain, hair coat grease accumulation, and scratching behavior in C57BL/6NCrl mice

Soft-pelleted, high-fat diets (HFD) are greasy and crumble easily leading to food wastage and hair coat grease accumulation when mice are fed using commercially available feeders. The ideal HFD feeder design should reduce food wastage, facilitate mouse weight gain, and...

Ge, Y., Alamaw, E. D., Ray, R. R. et al. 2025. Analgesic efficacy of a long-acting transdermal buprenorphine in rats (Rattus norvegicus)

Zorbium is the first long-acting transdermal buprenorphine (LAT-bup) approved by the FDA for relieving postoperative pain in cats for 72 h. This study aimed to investigate LAT-bup’s efficacy for attenuating postoperative mechanical and thermal hypersensitivity in a rat incisional pain...

Behavioral or nutritional drive: Which motivation affects rates of food grinding in CD1 mice?

Wire mouse feeders used in laboratory mouse cages typically hold enough food to feed 5 mice for two weeks. However, some mice gnaw the food provided into powder, which they do not ingest. The ground-up food fills the cage, resulting...

Infrared thermography for temperature measurement in adult female C57BL/6NCrl mice: A comparison with rectal probe and subcutaneous transponder

Body temperature is an easily measured clinical parameter that provides important information about an animal’s health and welfare. In the context of animal experiments, temperature monitoring provides relevant data needed to manage animal care and has been embraced as a...

Analysis of individually ventilated cage (IVC) microenvironments during 21-d cage change frequency for mice using two different bedding types

The Guide for the Care and Use of Laboratory Animals provides recommendations on sanitation frequencies for rodent caging equipment; however, it allows for performance standards to be used when extending this frequency for individually ventilated cage (IVC) caging. Our institution...

Behavior and safety in the use of canopy bridges by howler monkeys in an experimental environment

Urban sprawl advances over forested areas and threatens arboreal species, which often use roads, power lines, and rooftops to move, resulting in roadkill, electrocution, and dog attacks. One measure to mitigate these risks is the installation of canopy bridges, which...

Investigating the motivations of repetitive barrier interactions in Pogona vitticeps

Considerable research has demonstrated that the effective management of repetitive behaviours such as bar-biting and pacing relies upon understanding their motivations; however, this same research has revealed that repetitive behaviours can have a diverse array of motivations. In reptiles, repetitive...
