Environmental Enrichment

Effects of environmental enrichment on nonsocial and abnormal behavior of captive lowland gorillas (Gorilla gorilla gorilla)

The use of straw as bedding material appears to have a positive effect on both specific nonsocial [feeding/foraging] and abnormal behavior [coprophagy, regurgitation].

Improving the laboratory environment for nonhuman primates

Environmental improvements include construction of large indoor cages that allow pairing of experimental animals, a grass-covered 'playground' for breeding chimpanzee groups, and indoor/outdoor group housing for 'retired' experimental animals. In addition, we provide toys, perches, mirrors, and foraging devices, and...

Age and gender differences in response to food enrichment in family groups of captive marmosets (Callithrix, Callithrichidae)

The proximity of individual members of three family groups of marmosets was measured to two sources of food namely, on the introduction of their normal daily ration (baseline behaviour) as well as to a previously unfamiliar 'preferred' food [grapes]. Significant...

Environmental enrichment for laboratory rodents

What is in general understood by 'enrichment' is in fact no more than providing the animals with the possibilities to fulfill their basic needs, as we consider their species specific behaviour. .. Perhaps it would be more honest to use...

Effects of gnawing material, group size and cage level in rack on Wistar rats

Han:Wist rats were housed after weaning in groups of one, two, three or four in stainless steel cages with aspen chip bedding, with or without wooden gnawing blocks. The use of the blocks was assessed by Video recording and by...

Enrichment satisfying specific behavioural needs in early-weaned pigs

Pigs sniffed and nosed other pigs, belly-nosed, and chewed ears and tails less when they had access to a peat-filled rooting tray than in standard flat decks. A hanging rope was chewed more than artificial dogbones, which, in turn, received...
