Stryjek, R., Modlinska, K. 2022. Pre-exposure via wire-mesh partition reduces intraspecific aggression in male, wild-type Norway rats. Animal Welfare 31(2), 175-186.

There are instances when animals are introduced and expected to live alongside unfamiliar conspecifics within zoos, laboratories and wildlife sanctuaries. These pairings of unfamiliar animals may result in stress, trauma, or even death, in addition...

Black, V., Fenton, A., Ormandy, E. H. 2022. Protecting Canada’s lab animals: The need for legislation. Animals 12(6), 770.

Canada’s current non-legislated oversight system for animal-based science not only fails to adequately incentivize the replacement of sentient animals as best scientific practice in any meaningful way, but also fails to adequately protect those animals...

Ratuski, A. S., Weary, D. M. 2022. Environmental enrichment for rats and mice housed in laboratories: A metareview. Animals 12(4), 414.

Environmental enrichment has been widely studied in rodents, but there is no consensus on what enrichment should look like or what it should achieve. Inconsistent use of the term “enrichment” creates challenges in drawing conclusions...

Xu, C., Hou, M., Su, L. et al. 2022. The effect of environmental enrichment on laboratory rare minnows (Gobiocypris rarus): Growth, physiology, and behavior. Animals 12(4), 514.

Environmental enrichment is a method to increase environmental heterogeneity, which may reduce stress and improve animal welfare. Previous studies have shown that environmental enrichment can increase the growth rate, decrease aggressive and anxiety-like behaviors, improve...

Schütz, A. K., Krause, E. T., Fischer, M. et al. 2022. Computer vision for detection of body posture and behavior of red foxes. Animals 12(3), 233.

The behavior of animals is related to their health and welfare status. The latter plays a particular role in animal experiments, where continuous monitoring is essential for animal welfare. In this study, we focus on...

Blenkuš, U., Gerós, A. F., Carpinteiro, C. et al. 2022. Non-invasive assessment of mild stress-induced hyperthermia by infrared thermography in laboratory mice. Animals 12(2), 177.

Stress-induced hyperthermia (SIH) is a physiological response to acute stressors in mammals, shown as an increase in core body temperature, with redirection of blood flow from the periphery to vital organs. Typical temperature assessment methods...

Miller, A. L., Roughan, J. V. 2021. Welfare assessment, end-point refinement and the effects of non-aversive handling in C57BL/6 mice with Lewis lung cancer. Animals 12(1), 23.

Cancer-bearing mice are at risk of developing anxiety, pain, or malaise. These conditions may not only harm welfare but could also undermine data quality and translational validity in studies to develop therapeutic interventions. We aimed...

Tillmanns, M., Scheepens, K., Stolte, M. et al. 2022. Implementation of a pig toilet in a nursery pen with a straw-littered lying area. Animals 12(1), 113.

In this study, a pig toilet was installed on an organic pig farm, which enabled pigs to use a lying area littered with straw and keep it clean. The pig toilet was separated into a...

Furumoto, K., Ogita, K., Kamisaka, T. et al. 2021. Effects of multimodal analgesic protocol, with buprenorphine and meloxicam, on mice well-being: A dose finding study. Animals 11(12), 3420.

The anesthetic or analgesic agent of choice, route and frequency of anesthetic or analgesic administration, and stressors induce distress during the perioperative period. We evaluated a multimodal analgesic protocol using buprenorphine and meloxicam on the...
