Socialization strategies and disease transmission in captive colonies of nonhuman primates

In captive research environments for nonhuman primates (NHP), social housing strategies are often in conflict with protocols designed to minimize disease transmission. This is particularly true in breeding colonies, and is especially relevant when attempting to eliminate specific pathogens from...

The choice of bedding substrate, route of blood collection, and method of glucose determination all affect fasting blood glucose levels in C57BL/6 mice

This study compared 4 bedding substrates (corncob, paper, hardwood chip, and wire-bottomed cage inserts) and 2 routes of blood collection (lateral tail vein and retroorbital sinus) in 6 male C57BL/6NCrl mice. Mice were maintained with ad libitum food and water...

An effective, economical method of reducing environmental noise in the vivarium

High levels of ambient noise can have detrimental effects on laboratory animal wellbeing and may affect experimental results. In addition, excessive noise can reduce technician comfort and performance. This study was performed to determine whether inexpensive, passive acoustic noise abatement...

The use of bedding for groups of rhesus macaques

The use of substrate can have benefits to group housed macaques, including decreased aggression and increased foraging. Still, in some facilities, the use of bedding is perceived as time intensive and costly. In this study, we examined the use of...

Heat or insulation: Behavioral titration of mouse preference for warmth or access to a nest

In laboratories, mice are housed at 20-24C, which is below their lower critical temperature (30C). This increased thermal stress has the potential to alter scientific outcomes. Nesting material should allow for improved behavioral thermoregulation and thus alleviate this thermal stress....

Environmental enrichment and the laboratory zebrafish

The zebrafish (Danio rerio) is a small tropical minnow that is playing an increasingly big role in the world of scientific research. In the last year alone, researchers working with this diminutive fish from south Asia have discovered a new...

Training rats to shift into clean cages by using operant conditioning with positive reinforcement

Changing soiled cages is an integral part of husbandry, yet it can be a source of stress for both animal and animal care technician. In one case, large geriatric rats weighing around 1 kg did not have a positive response...

Current practices in a captive breeding colony of 13-lined ground squirrels (Ictidomys tridecemlineatus)

The authors provide an update to their 2006 report on the successful large-scale captive breeding of the 13-lined ground squirrel (TLGS; Ictidomys tridecemlineatus) in their colony, now a single-source supplier of purpose-bred TLGSs for several research institutions. With funding from...

Refining laboratory husbandry of venomous snakes of the family Elapidae

Unlike rodent management, captive maintenance of venomous snakes poses a considerably greater risk to operators and those around them: specific protocols are, therefore, required. Traditional techniques used by hobbyists and professionals involve frequent direct contact; agreed-upon safety procedures exist in...

Rats housed on corncob bedding show less slow-wave sleep

Despite the reported advantages of corncob bedding, questions have emerged about how comfortable animals find this type of bedding as a resting surface. In this study, encephalography (EEG) was used to compare the effects of corncob and aspen-chip bedding on...
