The problem with the dark bottom-row cage for non-human primates: A discussion by the Laboratory Animal Refinement & Enrichment Forum

Since there is evidence that the bottom cages can impact research, this should be a good reason to eliminate the two-tier system with its species-inappropriate bottom-tier cages.

Availability of feces-free areas in rodent shoebox cages

The Guide for the Care and Use of Laboratory Animals (the Guide) recommends that terrestrial mammals be provided space free of urine and feces in which to rest. To evaluate the feasibility of meeting this recommendation, the author examined the...

Behavior of laboratory mice is altered by light pollution within the housing environment

Environmental light-dark cycles play an important role in behavioural and physiological processes. It is essential that laboratory vivaria be designed to properly control the light conditions in which laboratory mice are housed; however, this is not universally the case. Some...

Behavior, body condition, and hair coat quality in differentially-reared rhesus macaques (Macaca mulatta)

Nursery rearing of rhesus macaques may be necessitated by management or research reasons as well as for the derivation of Specific Pathogen Free breeding colonies. Toward this last aim, the Tulane National Primate Research Center maintains both a colony derived...

The effect of rubber mats on preference and lying behaviour of group housed sows

This study analyses the preferences, as well as the lying behaviour, of sows with various types of mat in a group housing system lying area. The sows in the trial could choose between six bays with three lying surfaces (concrete,...

Effects of group stability on aggression, stress and injuries in breeding rabbits

On Swiss rabbit breeding farms, group-housed does are usually kept singly for 12 days around parturition to avoid pseudogravidity, double litters and deleterious fighting for nests. After this isolation phase there is usually an integration of new group members. Here...

Weight management in captive chimpanzees (Pan troglodytes) using a modified feeding device

Obesity, a common concern in captive chimpanzee populations, may lead to the development of various diseases and increase anesthetic risks. The aim of this study was to modify the current biscuit feeding devices and to utilize them in a way...

Behavioral effects of construction noises and vibrations on captive rhesus monkeys (Macaca mulatta)

The effects of irregular vibrations on rodents and livestock have been well documented, but little information about vibration effects is available in non-human primates. This study assessed the long-term impact of construction of 7 new buildings adjacent to an animal...

Effect of light intensity as determined by cage rack position on tumor growth in a mouse model of melanoma

Within the typical laboratory animal housing facility, animals may be exposed to varying intensities of light as a result of cage type, cage position, light source, and other factors. While evidence exists that light contamination during the dark phase of...
