The RSPCA/UFAW Rodent Welfare Group has held a one-day meeting every autumn for the last 28 years, so that its members can discuss current welfare research, exchange views on welfare issues and share experiences of...

Clay, A. W., Crane, M. M., Bloomsmith, M. A. 2022. Weight management towards physiological and behavioral wellbeing for chimpanzees living under human care. Zoo Biology 41(3), 200-217.

Across a period of 54 months, several changes were made to the feeding protocols of 32 adult chimpanzees living at the Yerkes National Primate Research Center Field Station. Before implementing any changes in diet, baseline...

Popper, A. N., Sisneros, J. A. 2022. The sound world of zebrafish: A critical review of hearing assessment. Zebrafish 19(2), 37-48.

Zebrafish, like all fish species, use sound to learn about their environment. Thus, human-generated (anthropogenic) sound added to the environment has the potential to disrupt the detection of biologically relevant sounds, alter behavior, impact fitness...

Ahmadi, F., Ghasemi, E., Alikhani, M. et al. 2022. Effects of group housing and incremental hay supplementation in calf starters at different ages on growth performance, behavior, and health. Scientific Reports 12(1), 3190.

The present study examined the effects of age at group housing and age at incremental hay supplementation in calf starters from 7.5 to 15% (dry matter, DM) and their interaction on growth performance, behavior, health...

Merlot, E., Meunier-Salaün, M.-C., Peuteman, B. et al. 2022. Improving maternal welfare during gestation has positive outcomes on neonatal survival and modulates offspring immune response in pigs. Physiology & Behavior 249, 113751.

Improving the housing of pregnant sows by giving them more space and access to deep straw had positive effects on their welfare, influenced their maternal behavior and improved the survival of their offspring. The present...

Leach, K. A., Charlton, G. L., Green, M. J. et al. 2021. Bedding system influences lying behaviour in dairy cows. Veterinary Record 190(7), e1066.

Background: The nature and depth of bedding material have an important influence on cow lying behaviour and comfort. Increasing use of recycled manure solids (RMS) as bedding led to an investigation of the influence of...

Scorrano, F. 2022. A new feeder device to provide cleaner and accessible diet gel to laboratory mice. Laboratory Animal Science Professional 10(2) (March/April), 50-52.

Gel solutions are simple to use, have a relative long shelf life and can be delivered with plastic cups or pouches. A common issue encountered by many institutions is that the gel becomes soiled quickly...

Buckmaster, C. L., Levesque, D., LaFollette, M. et al. 2022. Five hot topics in refinement of nonhuman primate neuroscience research. Laboratory Animal Science Professional 10(1) (January/February), 24-26.

Members of the North American 3Rs Collaborative (NA3RsC) refinement initiative have chosen to summarize developments in five hot topics of interest: 1. Tips for welfare-friendly transport, chairing, and restraint; 2. Guidance on refining food and...

Janavaris, M., Bader, L., Hansen, J. J. et al. 2022. Bedding as an enrichment strategy in group-housed Mauritian cynomolgus macaques (Macaca fascicularis). JAALAS 61(2), 159-164.

The research community is committed to improving the well-being of nonhuman primates by providing opportunities to express species-specific behaviors such as foraging. In the wild, macaques spend a large part of their day foraging; this...

Merley, A. L., Hubbard, J. S., Rendahl, A. K. et al. 2022. Behavioral and physiologic effects of dirty bedding exposure in female ICR mice. JAALAS 61(1), 42-51.

Exposure of sentinel mice to dirty bedding is commonly used in health monitoring programs to screen colonies for clinical and subclinical disease. Despite the potential stressors present in dirty bedding, including but not limited to...
