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...
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)...
The device consists of food treats ... mixed with shredded paper and stuffed into a 4 foot long section of cardboard tube which is cut into 4-inch lengths.
Adding a simple cow bell can increase use of vertical climbing poles and may have resulted in increased locomotor activity for [group-housed] captive chimpanzees. These data were collected in 1996/97 and the cow bells are...
A device was designed that allows us to blow forage [e.g., chicken scratch] into both empty and occupied cages and over a wide area.
The chimpanzees are fascinated with the bubbles floating .... run around sticking out their tongues, much as a child collecting snowflakes, and attempting to catch them - a bit bewildered as it disappears.
At the Primate Foundation of Arizona (PFA), we provide many different types of both destructible and indestructible objects, but seldom provide rigid plastic balls. They are frequently thrown about the enclosure during displays and have...
Subjects were tested on one single occasion each when they had access to a toy for 15 minutes. High percentages of use by two chimpanzees adjacent to social groups suggest that the King Kong toy...
A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so...
