Sex- and strain-related differences in the stress response of mice to CO₂ euthanasia

The 2013 edition of the AVMA Guidelines for the Euthanasia of Animals recommends a 10% to 30% volume displacement rate (VDR) per minute for CO2 euthanasia of rodents. Here we sought to evaluate behavior and plasma catecholamine levels in multiple...

Vibration-induced behavioral responses and response threshold in female C57BL/6 mice

Despite documented adverse effects, limits for rodent exposure to vibration in the laboratory animal facility have not been established. This study used female C57BL/6 mice to determine the frequencies of vibration at which mice were most sensitive to behavioral changes,...

Inoculation stress hypothesis of environmental enrichment

One hallmark of psychiatric conditions is the vast continuum of individual differences in susceptibility vs. resilience resulting from the interaction of genetic and environmental factors. The environmental enrichment paradigm is an animal model that is useful for studying a range...

Evaluation of infrared thermography for temperature measurement in adult male NMRI nude mice

Temperature monitoring during critical care provides important data required to guide treatment delivery. Body temperature is an easily quantified clinical parameter that can yield much information concerning the health of an animal. In research settings, temperature has been adopted as...

Interpreting neuroendocrine hormones, corticosterone, and blood glucose to assess the wellbeing of anesthetized rats during euthanasia

Current recommendations for assessing animal wellbeing during euthanasia suggest that measuring neuroendocrine hormones—such as ACTH, noradrenaline, and adrenaline—is preferable to measuring corticosterone and blood glucose because of the sensitivity of neuroendocrine hormones to the acute stress associated with rapid methods...

Home cage compared with induction chamber for euthanasia of laboratory rats

This study compared behavioral and physiologic changes in Sprague–Dawley and Brown Norway rats that were euthanized by using a 30% volume displacement rate of CO2 in either their home cage or an induction chamber; rats euthanized in the home cage...

Effects of music enrichment on individually housed male New Zealand white rabbits

The beneficial effect of music has been demonstrated in many species. Although commercially available music CDs intended for use with rabbits are available, these enrichments have not been critically evaluated to determine whether they reduce distress. In this study, we...

Body condition scoring for adult zebrafish (Danio rerio)

Body condition scoring (BCS) is a simple, rapid, noninvasive tool used to assess body condition in animals. In this study, we developed and validated a diagram-based BCS for adult zebrafish (Danio rerio), a popular research model. After receiving 20 min...

Preventing adverse events at research facilities

In this article, adverse events are defined as events that lead to significant injury or illness, unrelieved pain or distress, or the death of an animal, excluding those caused by IACUC-approved research procedures. The ability to identify possible adverse events...

Stranger danger? An investigation into the influence of human-horse bond on stress and behaviour

Human-animal bond is receiving increasing attention and is thought to confer benefits on well-being and performance in working animals. One important benefit of bonding is the “safe base” an attachment figure provides, which manifests in better coping and increased exploration...
