Tracking epidermal cortisol and oxytocin in managed bottlenose dolphins as potential non-invasive physiological welfare indicators

Growing concern over cetacean welfare has highlighted the need for rigorous, science-based assessment methods. Within this context, epidermal cortisol (ECC) and oxytocin (EOC) concentrations have emerged as potentially valuable physiological indicators. In this study, we first validated the analytical measurement...

Evaluation of the effects of enlarged housing on social play and reward seeking in rats

The legal minimum dimensions for laboratory rat housing prevent rats from fully performing their behavioural repertoire. In the regular cages, rats cannot run, climb, or even stand upright. The need to house rats in larger cages has been recognized internationally...

A study into viable wooden enrichment objects for Syrian Hamsters

It is known that due to the continual growth of their teeth, hamsters require a means by which to wear down their teeth and satisfy their natural desire to chew. Due to their foraging behaviour hamsters use their cheek pouches...

Alternative handling techniques to reduce anxiety in laboratory mice

The most common and widely used method to capture and transfer mice from cage to cage is to pick up and restrain the mouse by its tail. Recent studies at Liverpool University, however, have indicated that handling mice by their...

Mirror, mirror, on the wall

When mice are grouped together for the first time it is a novel experience filled with new sights and smells which will stress the animal too much and may cause aggression. It has been proven that mice can see a...

Confronting crunching: A refinement for the care of mice with the desire to crunch

‘Crunching’ is the term often used to describe the abnormal behaviour of mice that habitually crunch their pelleted diet, causing substrate levels to rise as the crumbs settle on the cage floor ultimately burying the nest. The aim was to...

Refinements to health monitoring

Green, Amber, Red monitoring system: If a mouse shows any of the listed amber signs, then monitoring is increased to either once or twice weekly (green HC). Mice with 3 amber signs should be on red HC (daily check). Mice...

Development of a sifting cage change method for rats to improve welfare

Normally during a cage change a small handful of dirty bedding is placed into the clean cage but I felt this was not enough to comfort the rats. After trialling a few methods I finally came up with a sieve...

A sweet change to the needle

Our Named Veterinary Surgeon (NVS) suggested providing post-operative pain relief in flavoured jelly to avoid the use of needles. We made up batches of non-medicated jelly to try them with first. We provided this nonmedicated jelly for three days before...

Environmental enrichment for a small colony of rats.

Our facility predominantly houses mice with a small number of rats used for brain cancer studies. Due to limited space and resource for equipment, we came up with some easy and cost effective ways to improve enrichment for the rat...
