Evaluation of disinfection methods for artificial plants in zebrafish (Danio rerio) recirculating water systems

The use of artificial plants as environmental enrichment for zebrafish (Danio rerio) in biomedical research facilities has been shown to provide benefits in animal welfare and care. Despite the benefits of artificial plants to zebrafish welfare, some research facilities are...

Measuring motivation for alfalfa hay in feedlot cattle using voluntary interaction with an aversive stimulus

Typical diets for finishing cattle are concentrate-rich and low in roughage, which may limit species-specific feeding behaviours and increase the risk of digestive disorder. Our objective was to measure how motivated finishing steers are to access alfalfa hay compared with...

Zebrafish nutrition: Everything known and to be known

Despite the widespread use of zebrafish (Danio rerio) as a research animal in many studies including toxicologic and biomedical research, the nutritional requirements of this species have yet to be determined. Several aquafeed companies currently produce zebrafish diets that, with...

The Chinchilla Consortium: Standardizing health and husbandry

Although chinchillas (Chinchilla lanigera, C. chinchilla) are categorized as a USDA-covered species, little information and guidance is available with regard to appropriate husbandry in a research setting. Here, the Consortium offers advice on standardized care of the chinchillas for health...

Use of a toy soak to maximize staff efficiency in cage wash operations

The Guide for the Care and Use of Laboratory Animals emphasizes that the primary aim of environmental enrichment is to enhance animal well-being. At our facility, at the end of a two-week cycle in a rodent cage, enrichment accessories and...

A fat tailed what?!: Navigating husbandry for the fat tailed dunnart (Sminthopsis crassicaudata)

FTDs are Australian carnivorous nocturnal marsupials, whose diet, environmental needs, and enrichment vary from typical research species. Due to the limited working knowledge on the husbandry and care of this species in a biomedical setting, information was compiled from multiple...

Comparison of agents to maintain hydration of Yucatan minipig skin

Itchy, dry skin…on pigs? Yes! Yucatan minipigs are commonly used in biomedical research and are prone to dry skin (xerosis) accompanied by itchy skin (pruritus). At our institution, minipigs were oiled twice weekly with lanolin to mitigate this condition, however,...

How outing conditions relate to the motivation of movement-restricted cattle to access an outdoor exercise yard

Assessing animal motivation to access a given resource is one method available to evaluate what to provide in the living environments of captive animals. Providing increased opportunities for movement can be seen as an important source of enrichment, but we...

Reduction in cold stress in an innovative metabolic cage housing system increases animal welfare in laboratory mice

Housing in metabolic cages can induce a pronounced stress response. Metabolic cage systems imply housing mice on metal wire mesh for the collection of urine and feces in addition to monitoring food and water intake. Moreover, mice are single-housed, and...
