Galvin, M. 2018. Refinement of tumour passage by optimisation of the tissue disaggregation protocol. Animal Technology and Welfare 17(3), 173-174 (IAT Congress 2018 Platform Presentation Abstract).

Surgical implantation of tumour pieces has been used regularly in the passage of tumour models. This involves an invasive surgical procedure, carried out under anaesthesia; ensuring mice have adequate pain relief and peri-operative care. The...

King, J. 2018. Report of the Enrichment; Awareness and Uptake Workshop 2018 on 26th June at College Court, Leicester. Animal Technology and Wefare 17(3), 163-167. [Meeting Report]

The point of the session was to have a collaborative discussion about environmental enrichment. The organisers wanted to know people’s experiences with enrichment, the barriers they have faced, if they have overcome any, and also...

Newman, S., Woodley, S. 2019. Time’s up for tick-over colonies… Do we now need to maintain so many GA mouse lines? Animal Technology and Welfare 17(3), 155-157.

The practice of continually breeding lines to maintain them as a live resource either in-between studies or indefinitely “just in case” is common practice in many animal facilities. This process of “ticking over” colonies has...

Brajon, S., Morello, G. M., Teixeira, M. S. et al. 2019. Social environment as a cause of litter loss in laboratory mouse: A behavioural study. Applied Animal Behaviour Science 218, 104827.

Perinatal mortality is a widespread problem in laboratory mouse breeding and is often manifested by the loss of the entire litter within the first days of life. High mortality is an animal health and welfare...

Nip, E., Adcock, A., Nazal, B. et al. 2019. Why are enriched mice nice? Investigating how environmental enrichment reduces agonism in female C57BL/6, DBA/2, and BALB/c mice. Applied Animal Behaviour Science 217, 73-82.

Compared to female mice raised in large, environmentally enriched (EE) cages, those from “shoebox” non-enriched (NE) cages demonstrate more stereotypic behaviour (SB) and depressive-like effects (i.e. learned helplessness; and inactive-but-awake behaviour [IBA], where a mouse...

Moreira, V. B., Mattaraia, V. G. M., Rodrigues, M. V. et al. 2019. Parental behavior and anxiety in isogenic and outbred mice given access to two types of nesting materials. Applied Animal Behaviour Science 215, 68-76.

The objective was to investigate if providing two types of nesting materials could modulate parental behavior and anxiety in laboratory mice. For that, 54 full-sib BALB/cJ and 50 randomly mated Swiss Webster mouse pairs were...

Steiner, A. R., Axiak Flammer, S., Beausoleil, N. J. et al. 2019. Humanely ending the life of animals: Research priorities to identify alternatives to carbon dioxide. Animals 9(11), 911.

The use of carbon dioxide (CO2) for stunning and killing animals is considered to compromise welfare due to air hunger, anxiety, fear, and pain. Despite decades of research, no alternatives have so far been found...

Axiak Flammer, S., Eskes, C., Kohler, I. et al. 2019. Alternatives to carbon dioxide—Taking responsibility for humanely ending the life of animals. Animals 9(8), 482.

Carbon dioxide (CO2) is commonly used to kill rodents. However, a large body of research has now established that CO2 is aversive to them. A multidisciplinary symposium organized by the Swiss Federal Food Safety and...

Neely, C., Lane, C., Torres, J. et al. 2018. The effect of gentle handling on depressive-like behavior in adult male mice: Considerations for human and rodent interactions in the laboratory. Behavioural Neurology 2018, 2976014.

Environmental factors play a significant role in well-being of laboratory animals. Regulations and guidelines recommend, if not require, that stressors such as bright lighting, smells, and noises are eliminated or reduced to maximize animal well-being...

Faller, K. M., McAndrew, D. J., Schneider, J. E. et al. 2015. Refinement of analgesia following thoracotomy and experimental myocardial infarction using the Mouse Grimace Scale. Experimental Physiology 100(2), 164-172.

What is the central question of this study? There is an ethical imperative to optimize analgesia protocols for laboratory animals, but this is impeded by our inability to recognize pain reliably. We examined whether the...
