Behavior patterns of laboratory animals

Placing of the cage on a rack even further reduces the available light. During experimentation, care must be exercised to use cages of the ... same placement to avoid variations in lighting. If this is not done, the investigator may...

Moving laboratory rhesus monkeys (Macaca mulatta) to unfamiliar home cages

The results of this study should serve as a warning to those who wish to observe behavior or take physiological measurements on monkeys. Removing an animal from its home cage prior to monitoring anything biological will probably affect the event...

An interval scale for studying and quantifying social relations in pairs of rhesus monkeys

When adult monkeys were paired [without prior familiarization!] the relationship typically began with intense action [in male-male pairings there were frequently several minutes of initial fighting] leading to establishment of a dominant-submissive relationship.

Environmental and genetic factors affecting laboratory animals: impact on biomedical research

The survey suggests that many investigators do not fully recognize the influence of environmental and genetic variables on experimental results.... Failure to give an adequate description of these variables makes it difficult, if not impossible, to duplicate an experiment in...

The nonhuman primate

Nonhuman primates are difficult and dangerous to handle. ... Large or aggressive animals such as male rhesus monkeys should not be handled without the use of chemical restraint. ... Animals are squeezed to the front of their cages and are...

Effects of the duration of individual or group housing on behavioral and adrenocortical reactivity in male mice

Basal corticosterone levels did not show a significant difference between single-housed and group-housed animals. When the mice were subjected to stress (e.g., open field exposure) corticosterone levels in single-housed subjects were consistently higher than in group-housed subjects, indicating an increased...

Factors affecting the development of isolation-induced hypertension in rats

Housing rats in groups seems to be less stressful for the animals than housing them alone.

Welfare and the structure of a battery cage: Size and cage floor preferences in domestic hens

Hens were found to prefer a larger [barren] over a smaller [barren] cage, and a cage with a grass floor over one with a wire floor. When cage size and floor type were opposed, hens chose to enter a small...

Drug-modulated behavioural responses to environmental enrichment

The home-cage activity of mice housed in either social or enriched sensory environments was continuously recorded for 23 days. During this period the mice were given daily injections of either strychnine, chlorpromazine, or saline. Both chlorpromazine and social rearing depressed...

Restraint in primate chair may cause unusual behavior in baboons: Electrocorticographic correlates and corrective effects of diazepam

The prolonged drowsy-like ECoG [electrocorticogram] and behaviour may therefore underline a reaction to the 'stress' conditions brought on by restraint.
