A new laboratory research model: The Damaraland mole-rat and its managed care

The Damaraland mole-rat (Fukomys damarensis) is a subterranean, hypoxia-tolerant, long-lived rodent endemic to southern and central Africa that is increasingly being used in laboratory research. Its husbandry needs and characteristics differ from traditional rodent research models. Here, we provide a...

Effect of adopting a timothy hay–based diet at weaning or in adulthood on urinary tract parameters in strain 13/N guinea pigs (Cavia porcellus)

Type of feed is an important consideration in herbivore colony management, yet limited studies report on the effects of diet on common conditions such as urolithiasis in guinea pigs. Urolithiasis is a well-documented cause of lower urinary tract disease in...

Moving toward evidence-based care: Measuring preferences in zoo-housed aquatic turtles using 24-h remote monitoring

Providing evidence-based care to animals is a common goal in zoos and aquariums. However, there are many understudied species with a lack of information available, which may result in suboptimal care for individuals of these species. Using preference tests to...

Weight as an indicator of enclosure suitability in Livingstone’s fruit bats (Pteropus livingstonii)

Obesity is common in zoo animals, and both dietary management and the provision of adequate opportunities for exercise are needed to tackle it. We used 30 years of records from Jersey Zoo to compare the weight and forearm length of...

Effects of temporary access to environmental enrichment on measures of laboratory mouse welfare

Laboratory mice are typically housed in “shoebox” cages with limited opportunities to engage in natural behaviour. Temporary access to environments with increased space and complexity (playpens) may improve mouse welfare. Previous work by our group has shown that mice are...

Exploring enrichment enjoyed by Zebrafish

Many studies highlighted that gravel is a preferred enrichment of zebrafish, therefore we were keen to explore this anecdotal evidence further, to ascertain if the spatial distribution of the zebrafish was significantly linked to the presence of physical enrichment within...

Refinements to goat housing for ADME collections

Typically, ADME studies are conducted using metabolism cages designed for the single housing of animals to enable the quantitative collection of urine and faeces, normally over a 1 to 2 week period. It is well documented that providing a stimulating...

Exploring the similarities between risk factors triggering depression in humans and elevated in-cage “inactive but awake” behavior in laboratory mice

Depression is a human mental disorder that can also be inferred in non-human animals. This study explored whether time spent inactive but awake (“IBA”) in the home-cage in mice was further triggered by risk factors similar to those increasing vulnerability...

The impact of cage dividers on mouse aggression, dominance and hormone levels

Home cage aggression in group-housed male mice is a major welfare concern and may compromise animal research. Conventional cages prevent flight or retreat from sight, increasing the risk that agonistic encounters will result in injury. Moreover, depending on social rank,...

IntelliCage: The development and perspectives of a mouse- and user-friendly automated behavioral test system
