Environmental Enrichment

Effects of specific noise and music stimuli on stress and fear levels of laying hens of several breeds

The results of the present study indicate that specific noise stimulus (90 dB versus 65 dB) causes stress and fear in laying hens and specific classical music stimulus (75 dB versus 65 dB) has a negative influence on their fearfulness.

Enrichment strategies for laboratory animals form the viewpoint of clinical veterinary behavioral medicine: Emphasis on cats and dogs

Understanding the range of behaviors, behavioral choices, and cognitive stimulation that cats and dogs exhibit under non-laboratory conditions can increase the ability of investigators to predict which enrichments are likely to be the most successful in the laboratory. Many of...

Environmental enrichment reduces Abeta levels and amyloid deposition in transgenic mice

Cerebral deposition of beta-amyloid (Abeta) peptides is an invariant pathological hallmark in brains of patients with Alzheimer's disease (AD) and transgenic mice coexpressing familial AD-linked APP and PS1 variants. We now report that exposure of transgenic mice to an enriched...

Rx for mice: Take enrichment and call me in the morning

In a first phase, the effectiveness of several enrichment devices was evaluated: flavored nylon chew bones, colored tunnels, igloo shaped houses, and a life-sized rubber mouse. Mice, whether alone or in a group, had constant interaction with the houses.... I...

Stereotypies and other abnormal repetitive behaviors: Potential impact on validity, reliability, and replicability of scientific outcomes

Normal behavior plays a key role in facilitating homeostasis, especially by allowing the animal to control and modify its environment. Captive environments may interfere with these behavioral responses, and the resulting stress may alter many physiological parameters. Abnormal behaviors indicate...
