A study in refining husbandry techniques for the in-house breeding of rats and mice

Because of the nature of genetically altered animals the probability tht they are deliberately or unintentionally altered in their morphology, physiology and or behaviour can lead to the need to make changes in how we maintain each strain. We are...

The impact of different blood sampling methods on laboratory rats under different types of anaesthesia

Rats with implanted telemetry transponders were blood sampled by jugular puncture, periorbital puncture or tail vein puncture, or sampled by jugular puncture in carbon dioxide (CO2), isoflurane or without anaesthesia in a crossover design. Heart rate, blood pressure and body...

Preparation of animals for research — Issues to consider for rodents and rabbits

This article provides details to consider when preparing to use animals in biomedical research. The stress of transport and receipt of animals into a new environment mandate the need for a period of stabilization and acclimation. This allotment of time...

Fecal corticoid metabolites in aged male and female rats after husbandry-related disturbances in the colony room

Over a 3-h period, 10 male and 10 female Fischer 344 rats (age, 82 wk) were exposed to a series of events that can occur in a colony housing room (keys jingling, cage lids opening, alteration of the light cycle)....

Do audible and ultrasonic sounds of intensities common in animal facilities affect the autonomic nervous system of rodents?

Evidence demonstrates that audible noise and ultrasound have deleterious effects on rodent physiology. ... The data obtained from this study indicate that audible noise, but not ultrasound, affects the ANS. Because the cardiovascular, respiratory, renal, and gastrointestinal systems are under...

Long-term effects of cage-cleaning frequency and bedding type on laboratory rat health, welfare, and handleability: a cross-laboratory study

Cleaning frequency had no clear impact on rat welfare, although frequent cleaning decreased ammonia concentrations and handleability, and non-aggressive skirmishing was highest in weekly cleaned rats. Surprisingly, bedding type did not affect ammonia, but all ammonia readings were unexpectedly low....

Acute effects of cage cleaning at different frequencies on laboratory rat behaviour and welfare

We found no evidence that cage cleaning caused rats any acute decrease in welfare - a finding consistent with additional data we have obtained on the lack of preference by rats for soiled over clean cages, and a lack of...
