Sound levels in rooms housing laboratory animals: An uncontrolled daily variable

It is clear that the acoustic environment of laboratory animals is a daily variable that is usually uncontrolled and that may have important implications for behavioural and physiological experiments and for animal welfare.

The rest/activity rhythm of the laboratory rat housed under different systems

The mean activity during the hours of darkness for all housing situations was in the region of 50%, while during the day this was reduced to between 14-19%. No matter what housing system [single versus double commune box] and enrichment...

The antinociceptive effect of non-noxious sensory stimulation is mediated partly through oxytocinergic mechanisms

The release of opiate peptides is stimulated by oxytocin neurotransmission. Oxytocin treament has an anti-stress and analgetic effect.

Effects of environmental enrichment on aggressive behavior, dominance hierarchies, and endocrine status in male DBA/2J mice

The provision of a horizontal labyrinth consisting of vertical dividers with only a few openings enhanced territorial tendencies in groups of male mice, leading to increased aggression. Findings suggest that keeping adult male mice in structured cages can result in...

Chronic monitoring of cardiovascular function in the conscious guinea pig using radio-telemetry

An implantable radio-telemetry device for chronic monitoring of arterial pressure and heart rate in the conscious guinea pig was validated against measurements using an exteriorized, indwelling catheter. There were no significant differences between simultaneous measurements in animals instrumented with both...

Individual housing modulates daily rhythms of hypothalamic catecholaminergic system and circulating hormones in adult male rats

Male rats housed individually had higher levels of corticosterone and prolactin than did those housed six per cage.

Effect of cage height and environmental enrichment on rat’s behaviour

Rats housed in the high cages [20 cm] showed more interest in the [gnawing] sticks than rats housed in the low cages [15 cm]. Rats in the high cages had more contact with the paper. .. Unlike the observation of...

The cage design affects intermale aggression in small groups of male laboratory mice: strain specific consequences on social organization, and endocrine activations in two inbred strains (DBA/2J and CBA/J)

The provision of a horizontal labyrinth consisting of vertical dividers with only a few openings enhanced territorial tendencies in groups of male mice, leading to increased aggression. Findings revealed strainspecific environmental effects on both social organization and endocrine states.
