An ethological approach to housing requirements of golden hamsters, Mongolian gerbils and fat sand rats in the laboratory ? A review

When housing hamsters and gerbils little has been done to identify the preferences of these species. The solitary nature of fat sand rats and hamsters is often discordant with housing practices in animal laboratories. This article provides a comparison of...

Pair-housing of male and female rats during chronic stress exposure results in gender-specific behavioral responses

In conclusion: pair-housing had a stress-reducing effect on behavior in male rats. Isolation of females was stressful by itself. Pair housing of females was not able to prevent stress-induced behavioral changes completely, but appeared to reduce the effects of chronic...

Comparison of technicians’ ability to detect clinical signs in rats housed in solid-bottomed cages with bedding versus wire-bottomed cages

The only difference observed was a diminished ability to detect blue urine from new methylene blue adminstation in wire-bottomed cages. Concerns about the technical staff's inability to detect clinical signs in toxicology tests should not prevent investigators from using solid-bottomed...

The reinforcing property and the rewarding aftereffect of wheel running in rats: a combination of two paradigms

Wheel running reinforces the behavior that generates it and produces a preference for the context that follows it. The goal of the present study was to demonstrate both of these effects in the same animals. Twelve male Wistar rats were...

Troubles shared are troubles halved: Stress in rats is reduced in proportion to social propinquity

The objectives of this study were to: 1) evaluate how stocking density at the feed bunk affects feeding and social behavior of dairy cows; and 2) determine if this effect is further influenced by the type of feed barrier used....

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...
