Assessment of the use of two commercially available environmental enrichments by laboratory mice by preference testing

All three strains of mice showed a significant preference for the paper box. The paper box was much lighter [20 g] than the plastic box [95 g]. This allowed the mice to move the paper box around, manipulate it and...

Impact of environmental enrichment in mice

The result of this study suggests that values of body weight, haematological variables .... were not significantly influenced by our enrichment design [nestbox plus climbing structure], but that enrichment seemed [sic] to have effects on the variation and the strain...

Foraging enrichment for individually housed horses: Practicality and effects on behaviour

The results indicate that the potentially beneficial behavioural effects of short-term multiple forage provision do persist when horses are managed on a MF [multiple forage] diet [long-chop and short-chop forages] for a 7-day period. They suggest that a MF diet...

Modifications to husbandry and housing conditions of laboratory rodents for improved well-being

A review of the literature shows that a consensus on the definition of changes constituting environmental enrichment has yet to be reached. For this reason, the results of studies on the effects of rodent enrichment are inconsistent. In many cases,...

Effects of a cage enrichment program on heart rate, blood pressure, and activity of male sprague-dawley and spontaneously hypertensive rats monitored by radiotelemetry

Enrichment comprised a simulated burrow (Rodent Retreat), then a food foraging item (rat cannoli) 2 days later, and a paper bag of bedding for shredding (Nestpak) after another 2 days. Data were collected under undisturbed conditions and before and after...

Effect of two types of environmental enrichment for singly housed mice on food intake and weight gain

Adult mice showed no change in either food intake or weight gain when an Igloo refuge was introduced into their cage.

Foraging device for cynomolgus macaques

A foraging device is described. We do not use it to feed our primates their daily rations, just to provide an enrichment opportunity for them. No data are included in this article.

USDA perspectives on environmental enrichment for animals

This article provides a brief historical background of the events and circumstances that led to the 1985 Animal Welfare Act (AWA) amendments. It describes the development of the regulations promulgated by the US Department of Agriculture (USDA) in 1991 as...

Environmental enrichment to address behavioral differences between wild and captive black-and-white ruffed lemurs (Varecia variegata)

Behavioral enrichment experiments were carried out in which whole rather than chopped fruit was provided and presented in a more naturalistic manner [whole fruit suspended by sisal or jute from wooden polses]. ... Manual manipulation of dietary items increased. Time...
