Environmental Enrichment

Rotational use of a recreational cage for the environmental enrichment of Japanese macaques (Macaca fuscata)

The study provides evidence that the problem of boredom and declining use of enrichment devices usually seen with nonhuman primates can be addressed by rotating the animals through a recreation cage larger than the standard individual cage. The rotational use...

The effects of different types of feeding enhancements on the behaviour of single-caged, yearling rhesus macaques

Enrichment techniques designed to encourage captive primates to spend more species-appropriate amounts of time in foraging behaviours have been successful. The present study measured the behavioural effects of four feeding enhancements: two devices (mats and puzzles) and two foods (produce...

Enrichment effects on rhesus monkeys successively housed singly, in pairs, and in groups

Subjects were more socially oriented when pair-housed than when living in small groups. Inanimate enrichment did not affect behavior ... although enhancements were well-used by singly-caged yearlings and pair-housed juveniles. Subjects used enrichment less frequently when housed in groups. The...

Primate housing facilities for pharmaceutical research in Switzerland (an example)

According to the Swiss Animal Welfare Legislation, the minimal enclosure area for macaques of the size of rhesus or cynomolgus monkeys for experimental purposes is 15 cubic meters. In such an enclosure up to 5 adult animals may be kept...

Environmental enrichment: does it reduce barbering in mice?

One of the problems in maintaining group-housed mice is barbering one or more mice chewing (barbering) the fur and whiskers of other mice. A group of 300 mice of both sexes, which are being studied over their lifetime, were housed...

Behavioural effects of cage enrichment in single-caged adult cats

A loss of interest in objects [tennis ball suspended 12 cm above the floor; 12 cm diameter x 40 cm long wooden log hooked against the wall] over time was observed. On the fifth day after the introduction, [single-caged] cats...

Rodent enrichment devices – evaluation of preference and efficacy

The mice preferred cotton nestles and cardboard rolls over wooden block and commercial toys. When animals wearing wound clips were exposed to the preferred enrichment, premature wound clip removal decreased, suggesting a positive effect of enrichment on the psychological well-being...
