Refining mouse handling – do we or don’t we? An animal technologist’s perspective

Recent research in the industry identified that picking up mice in a tunnel or cupping them in the hand significantly reduces their stress levels. As Animal Tecgnologists, we could see advantages and disadvantages with this change for the animals, staff...

Introduction of gang caging for group housed rats

Using an existing gang cage designed for ferrets, we developed a version that would be suitable for housing rats. Caging consisted of 3 floors with a combined floor area of 11620m, connected by 2 ladders. Each individual unit can be...

Spider and chips: The use of internal Radio Frequency Identification (RFID) chips as a minimally invasive method to measure internal body temperatures in invertebrates

Internal RFID transponders have been used in vertebrates for many years, however studies into their use in invertebrates are less well represented in the literature. The use of RFID transponders for internal temperature measurement represents a less invasive alternative to...

Synchronisation of oestrous cycle on C57BL/6J mice after the introduction of a hanging perforated container with bedding soaked by the excretions of male mice

Synchronisation of oestrous cycle is a commonly used method to manage pregnancies either for breeding or for research purposes. Based on Whitten effect, the aim of our study was to introduce a new refined method for oestrous synchronisation and to...

Measuring physiological stress in the common marmoset (Callithrix jacchus): Validation of a salivary cortisol collection and assay technique

Cortisol levels are often used as a physiological measure of the stress response in captive primates, with noninvasive measures of this being an important step in welfare assessment. We report a method of collecting saliva samples voluntarily from unrestrained captive...

Behavioral responses of CD-1 mice to conspecific and heterospecific blood odors and to a blood odor component

The odor of blood may have both aversive and attractive properties for mammals, depending on the species of the odor donor and the species perceiving the odor. To better understand the informational content of blood odor for a prey species...

Vocal correlates of emotional reactivity within and across contexts in domestic pigs (Sus scrofa)

Vocalizations have long been recognized to encode information about an individual's emotional state and, as such, have contributed to the study of emotions in animals. However, the potential of vocalizations to also encode information about an individual's emotional reactivity has...

Assessing the exploratory and anxiety-related behaviors of mice

Ample studies have shown that housing can affect the health, welfare and behavior of mice and therefore, the outcomes of certain experiments. The aim of this study was to investigate if three widely used housing systems, Open Top Cages (OTC),...

Social housing and social isolation: Impact on stress indices and energy balance in male and female Syrian hamsters (Mesocricetus auratus)

Although Syrian hamsters are thought to be naturally solitary, recent evidence from our laboratory demonstrates that hamsters may actually prefer social contact. Hamsters increase their preference for a location associated with an agonistic encounter regardless of whether they have “won”...

Female rats display fewer optimistic responses in a judgment bias test in the absence of a physiological stress response

Metabolic cages are a type of housing used in biomedical research. Metabolic cage housing has been demonstrated to elicit behavioural and physiological changes in rodents housed within them. The nature of this effect has been characterized as anxiogenic. However, few...
