Clinical pathology and cardiovascular parameters are not influenced by housing rats under increased environmental complexity

Since the release of the revised Appendix A from the Council of Europe for housing of laboratory animals there have been claims that laboratory animals should be housed under more complex conditions; known popularly as enrichment. A number of studies...

Anxiolytic effect of music exposure on BDNFMet/Met transgenic mice

Brain-derived neurotrophic factor (BDNF) has been reported to play important roles in the modulation of anxiety, mood stabilizers, and pathophysiology of affective disorders. Recently, a single nucleotide polymorphism (SNP) in the BDNF gene (Val66Met) has been found to be associated...

Environmental-enrichment-related variations in behavioral, biochemical, and physiologic responses of Sprague-Dawley and Long Evans rats

The behavioral, biochemical, and physiologic consequences of 6 wk of environmental enrichment were evaluated in male Long Evans and Sprague-Dawley rats and compared with those of rats in standard single-housing conditions. Standard housing provided little or no social or physical...

Taming anxiety in laboratory mice

Handling experience (which includes routine maintenance) can have positive or negative effects on stress responses that influence experiments, depending on the animals' experience during handling. The most common method used to capture and handle laboratory mice is to pick up...

The effects of environmental enrichment through larger cage type on behavioral patterns in rats

Most behavioral research is conducted in lab-housed animals due to the significant advantages of a controlled environment. In an effort to enhance the welfare and to obtain more realistic measures of behavior, larger cages with an additional raised platform have...

Effects of environmental enrichment and housing system on weight gain of C57BL/6 mice

Our goal was to evaluate the effect of treatment represented by enrichment with cotton balls, and the housing system, by comparing the conventional (open cage) and the ventilated cage (IVC) systems on the weight gain of C57BL/6 inbred mice, as...
