Environmental Enrichment

Cage size as a factor in environmental enrichment

Cage size significantly affected 38-day gross body weight, open-field activity and defecation, running-wheel activity, exploration, and water consumption. .. Rearing in large cages, either wire or Plexiglas, appears to reduce emotionality... The results of this experiment indicate that cage size...

Enrichment and occupational devices for orangutans and chimpanzees

A heavy metal cylinder, 60 cm long and 45 cm in diameter, was capped on each end and bolted to a platform. Three 8 cm holes in the cylinder allowed access to the inside. A short section of a rubber...

Drug-modulated behavioural responses to environmental enrichment

The home-cage activity of mice housed in either social or enriched sensory environments was continuously recorded for 23 days. During this period the mice were given daily injections of either strychnine, chlorpromazine, or saline. Both chlorpromazine and social rearing depressed...

Ever been close to a nosey pig?

Rooting seems to be a very important behaviour in pigs. Its major function is exploratory. Accepting responsibility for farm animals' welfare means more than providing food, water and shelter. The animals' needs, including exploration must also be taken into account....

Paradoxical sleep and memory (I): Selective alterations following enriched and impoverished environmental rearing

Mice were reared in either enriched (EE), social control, (SE), or impoverished (IE) environments for 30 days. Environmental enrichment results in a significant and selective increase in paradoxical sleep (PS, or REM sleep) and also enhances recall of a multiple-trial,...

A resting platform for dog pens

After converting our dog holding facilities from commercial dog cages to pen type enclosures, it became apparent that suitable resting platforms were needed. Clear acrylic plastic was used to construct the resting platforms.

Growth and the plasma concentrations of growth hormone and prolactin in chicks: Effects of ‘environmental enrichment’, sex and strain

The enriched boxes were similar to the bare ones but also contained the following objects: two large red rubbing bungs, a golf ball, a bottle top, two coloured table tennis balls hanging from the cage lid, two lengths of string......
