The use of woodchips as bedding for 16 juvenile chimpanzees (Pan troglodytes) was evaluated for the effects on behaviour, health and husbandry practices. Woodchip bedding was placed in two outdoor play areas for five consecutive...
The sequence in which 14 laboratory rhesus macaques left their home enclosure during a routine catching procedure was recorded on 30 occasions during 6 weeks. The animals were trained to voluntarily exit one by one...
Animals living in upper-row cages were more active and engaged in more close contact amicable behavior than animals living in lower-row cages. Those located in the half of the room nearer the window were more...
New techniques were developed to avoid the manual transfer - and the associated health hazard - of caged macaques during handling procedures.
Ordinary feeder-boxes were converted into food puzzles by remounting them onto the mesh of the front of the cages, away from original access holes. The total amount of time [pair-housed] adult male rhesus macaques engaged...
An attempt was made to encourage more foraging behaviour in eight pair-housed adult rhesus macaques (Macaca mulatta). No special device and no special food were used. Daily commercial dry food rations consisting of 33 bar-shaped...
Review of the implications of experimental or management-related manipulations of the social environment of captive primates for the animals' welfare. Relatively little empirical work has been done on the effects of manipulation of the social...
In this study, the preference of X. laevis for different housing conditions were examined. X. laevis preferred dark backgrounds, a water temperature between 20C-22C and the deeper parts of the test basin. Red earthenware pipe...
Training technique is described. Thirty-seven [group-housed] captive chimpanzees were trained using operant conditioning to enter a transfer box. [Age and sex of subjects is not provided.]
Ninety-nine of the biscuits were placed in a freely accessible dish attached to the mesh of the front of the cage. Thirty-three biscuits were offered in a food puzzle. Twenty-five percent (4/16) of the subjects...
