Eight single-caged adult rhesus macaques were given the choice of freely collecting their standard food ration, i.e. 33 biscuits, from an ordinary food box or working for its retrieval from a custom- made food puzzle...
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...
Food cannot be collected without effort, but must be plucked [from the net] item by item, resulting in an increase of feeding time. The net is attached to the top of the cage.
Our laboratory, a short time after the introduction of woodchip, became infested with domestic mice. ... We decided to adequate the original idea changing woodchip with argilla espansa ... a material that is used in...
Results show that the feeding board [on which seeds were scattered] were almost always in use [during 30-minute observations]. ... There was no evidence that the position in which the feeding board was placed [high...
Differences in housing location and the amount of room disturbance associated with blood sampling have a significant impact on cell counts, but not on ACTH or cortisol levels. We believe that the critical factor that...
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...
Caretakers should seek knowledge of the natural lifestyles of the primates in their charge, and attempt to reproduce in the captive environment the salient aspects of the natural habitats that are biologically relevant to the...
The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers...
The objective of toxicology and pharmacology studies is to detect change or variation from normal and to interpret the significance of such change, with the intention of assessing risk to man. With non-human primates (NHPs)...
