Psychological well-being of primates in captivity

Recent amendments to the Animal Welfare Act will, upon taking effect, require that researchers who maintain nonhuman primates in captivity house their animals in such a way as to “promote their psychological well-being.” Unfortunately, no consensus presently exists in terms...

Measurements of core temperature in spontaneously hypertensive rats by radiotelemetry

Handling and restraint can cause significant increases in core temperature. When SH [spontaneously hypertensive] rats are not stressed or disturbed, their core temperatures are not significantly different from that of normotensive WKY [Wistar-Kyoto] rats.

Primate psychological well-being: A comparative approach to environmental enrichment for captive primates

The presence of woodchips and especially the introduction of [unspecified] objects, reduced general locomotor activity in the capuchins; however, the objects had no such effect on the lemurs, and the provision of woodchips plus grain almost doubled their rates of...

Social dominance in dairy cattle and influences of housing and management

Although there is much information available on social dominance in dairy cattle the concept is still regularly discussed. The results of four experiments with dairy cows, together with the relevant literature are used to discuss the influence of housing and...

Ecology and social behaviour of the Mongolian gerbils, Meriones unguiculatus, at Xilinhot, Inner Mongolia, China

Observations were made of social and territorial behaviour in a wild high-density population of Mongolian gerbils. The social units were multi-male, multi-female age-structured groups, judged to be families. The operational sex ratio was male biased. Group size varied from two...

Polyvinyl chloride piping as perch material for squirrel monkeys

An additional unexpected benefit of the PVC piping has been a decrease in dorsal tail-head abrasions, frequently seen in squirrel monkeys that sit on the stainless steel flooring of standard primate cages.
