Lemur

The behavioral profile and environmental enrichment of a squirrel monkey colony

Five options were tested in alternation: crushed monkey chow in wood shavings, plastic ball, empty plastic bottle, PVC tube with finger holes and loaded with litter-nut-dried fruit mix, plastic jug with litter-nut-dried fruit mix. The two food dispensing objects were...

Traditional handling procedures of laboratory nonhuman primates are an intrinsic source of distress: What can be done?

With some professional expertise and goodwill, there should be no real need to resort to forceful restraint when doing research with nonhuman primates.

Lemur feeding: It’s in the trees

One end of the vine is secured around the middle of a whole fruit or vegetable like a carrot, while the other end is secured to a branch of a tree in the exhibit. To make this feeding activity more...

Primates and coconut halves

Mashed food was pressed into the inside of coconut shell halves and hung almost out of reach. This worked very well for the lemurs. It lengthened their feeding time and made them work for their food. No data are included...

Enriching the behaviour of captive ruffed lemurs with a more naturalistic method of food presentation

By providing whole rather than chopped fruits, a greater range of postures and increased manual manipulation of dietary items could be obtained. Time spent feeding and foraging also increased significantly.

Space requirement stipulations for caged non-human primates in the United States: A critical review

Cage space requirements for non-human primates in the United States of America are less than those in European countries. Studies in support of the assumption that the US legal minimum cage size provides adequate space have limited value because they...

Effects of feeding enrichment on ruffed lemurs varecia variegata veriegata and varecia v. rubra

Providing food at a high level in [mesh] baskets [rather than scattering it on/near the ground] increased arboreal activity outside feeding times and reduced aggression over food.

Behavioural enrichment of ruffed lemurs (Varecia variegata) based upon a wild-captive comparison of their behaviour

Effective feeding enrichment for non-human primates: A brief review

There is a growing awareness that non-human primates kept in zoos and laboratories deserve more species-appropriate stimulation because of their biological adaptation to a challenging environment. Numerous attempts have been made to effectively emulate the gathering and processing aspects of...
