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...
Simple bamboo pipe feeder is described and tested in group-housed animals. The aim of the study was to [successfully] increase foraging time with an increasing number of feeding devices [brawn bowl, bamboo pipe]. ... Prior...
The response of four singly caged baboons to radio music was measured using behavioral and physiological indices. Heart rate and blood pressure, measured through a tether system, as well as behavior, were recorded during a...
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...
Eight baboon groups (Papio sp.) were observed for over one hundred scan samples both before and after the provision of structural enrichment. Additions to their home-cage included a galvanized ladder suspended horizontally by chains and...
The aquarium [with a single goldfish] was attached to the outside of the chimpanzee's cage ... so that the single-caged subject was able to touch the aquarium but not the fish itself. At the conclusion...
Training protocol is described. These findings lead to the conclusion that training nonhuman primates to cooperate during venipuncture in their familiar home environment offers a methodological refinement by eliminating significant cortisol responses.
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...
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...
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...
