Husbandry & Management

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...

Preferences of group-housed female mice regarding structure of softwood bedding

Bedding influences various parameters in the housing of laboratory mice, such as health, physiology and behaviour (often considered as being integral parts of welfare). Notwithstanding existent studies about bedding preferences of individually tested mice, data about group-housed mice are still...

Effects of cage density, sanitation frequency, and bedding type on animal well-being and health and cage environment in mice and rats

Ongoing studies and historical data support the finding that deviations or exceptions from the cage density and sanitation frequency standards set forth in the Guide do not negatively affect animal health, welfare, or production parameters at our institution. These parameters...

Individual differences in temperament and behavioral management practices for nonhuman primates

This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also predict which animals may be...

Improved nonhuman primate social housing using visual cues associated for an intensive research study

Lean management-based visual tools have been used to improve the quality of animal care associated with a complex research study involving immune-compromised cynomolgus monkeys (M. fascicularis) in various postsurgical recovery states. In order to effectively care for such research animals,...

Physiological and behavioural stress responses in cynomolgus macaques (Macaca fascicularis) to noise associated with construction work

Manzanita wood: A sanitizable enrichment option for nonhuman primates

Wooden objects are often used as nonhuman primate enrichment to provide variety and novelty, promote exploratory behavior, and supply an outlet for curiosity. However, concerns have been raised regarding the ability to sanitize wood by using conventional cage-wash procedures. To...
