Saliva sampling in dogs: How to select the most appropriate procedure for your study

Saliva sampling is an easy, noninvasive method to assess short-term physiological changes, and as such is a valuable addition to behavioral studies in dogs. Different methods for collecting saliva samples in dogs have been reported in literature, and there appears...

Home sweet home cage

This feature describes creative ways in which technology can be used to study animals within their home cages, eliminating the need to handle, restrain, and separate them from cage mates. One example includes voluntary brain imaging in mice. In biomedical...

Non-lethal sex identification of sea urchins: Method and advantages

A simple method for sex determination can reduce the number of sea urchins used in the lab and help to optimize experimental design. Our new methodology developed with Paracentrotus lividus is simple and inexpensive, requiring only a syringe and a...

Minimally-invasive, microneedle-array extraction of interstitial fluid for comprehensive biomedical applications: Transcriptomics, proteomics, metabolomics, exosome research, and biomarker identification

Interstitial fluid (ISF) has recently garnered interest as a biological fluid that could be used as an alternate to blood for biomedical applications, diagnosis, and therapy. ISF extraction techniques are promising because they are less invasive and less painful than...

Environmental enrichment prevents pup mortality in laboratory mice

Early death of mouse pups is a commonly known problem in breeding mice colonies, which is still often regarded as ‘normal' or is even overlooked due to the counting procedures applied. As reduced breeding performance probably indicates reduced well-being, this...

Multiple refinements to the anaesthetic protocol for laparoscopic orthotopic kidney auto-transplantation in a pig model

Fifty-four pigs (Sus scrofa, Large White cross) from a commercial pig farm were anaesthetised over a six-year period from October 2011. The procedural stages included initial instrumentation for intra-operative monitoring, laparoscopic nephrectomy, preparation of the kidney graft, orthotopic auto-transplantation by...

Optimal tube length of orotracheal intubation for mice

Endotracheal tube (ETT) management is an essential technique in handling mice with mechanical ventilators. Malposition into bronchi causes not only lethal complications for them but also less efficient mechanical ventilation. However, in general, it is difficult to know whether the...

Improved timed-mating, non-invasive method using fewer unproven female rats with pregnancy validation via early body mass increases

For studies requiring accurate conception-timing, reliable, efficient methods of detecting oestrus reduce time and costs, whilst improving welfare. Standard methods use vaginal cytology to stage cycle, and breeders are paired-up using approximately five proven females with proven males to achieve...

Anaesthetics and analgesics used in adult fish for research: A review

The number of fish used in research has increased in the last decades. Anaesthesia is required when fish must be held immobile and it is crucial to promote fish welfare, because these vertebrates can show signs of stress and/or pain...

Automated monitoring of mouse feeding and body weight for continuous health assessment

Routine health assessment of laboratory rodents can be improved using automated home cage monitoring. Continuous, non-stressful, objective assessment of rodents unaware that they are being watched, including during their active dark period, reveals behavioural and physiological changes otherwise invisible to...
