Floor space needs for laboratory mice: C57BL/6 males in solid-bottom cages with bedding

Different floor space allocations of cages that were barren except bedding were tested in groups of 3 male mice. Space reduction - from 129 to 32 square cm per mouse - had no impact on body weight gain; but with...

Effects of housing density on C57BL/6J mice housed in three cage types

This 8-week study was initiated to investigate the impact of floor space on the health and well being of C57BL/6J (B6) mice, a strain commonly used by the scientific community. Male and female 4-week-old mice (sexes housed separately) were maintained...

Effects of housing density and cage floor space on three strains of young adult inbred mice

Some recommendations in the Guide for the Care and Use of Laboratory Animals (the Guide) are based on best professional judgment. Our current efforts are directed toward replacement with data-driven standards. We demonstrated earlier that young adult C57BL/6J mice could...

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...

Effects of short- and long-term changes in spatial density on the social behavior of captive chimpanzees (Pan troglodytes)

The purpose of this study was to test the conflict-avoidance and tension-reduction models by examining the effects of both short-term (1-2 days) and long-term (6 months) changes in spatial density on social behavior in 23 adult captive chimpanzees (6 males,...

Effect of cage density and sex on growth, food utilization and some stress parameters of young rabbits

The aim of the experiment was to study the effects of cage density (1, 3 and 5 rabbits per cage) and sex (male and female) on stress parameters of young rabbits. A total of 90 (45 male and 45 female)...

Behaviour of growing rabbits under various housing conditions

The aim of this research was to assess the effects of environmental variables (group size, stocking density, floor type, environmental enrichment) on behaviour as a welfare indicator of growing rabbits. Two experiments were carried out with Pannon White rabbits. In...

The effect of type of rooting material and space allowance on exploration and abnormal behaviour in growing pigs

The experiment aimed to investigate the effect of type of rooting material and space allowance on explorative and abnormal behaviour in growing pigs. Thirty-six pens with partly slatted concrete floor were allocated to one of four treatments: (1) low space...

A meta-analysis of the combined effect of housing and environmental enrichment characteristics on the behaviour and performance of pigs

To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were applied to evaluate the effects...
