Effects of acute stress on serum LH and prolactin in intact, castrate and dexamethasone-treated male rats

Placing rats into transfer boxes and moving them to another room triggers a significant rise in plasma prolactin and LH.

The rat’s long-term preference for complexity in its environment

Single-housed rats demonstrated a marked preference for high complexity during 'day' conditions probably because spatial complexity elicited shelter/relaxation responses. Complexity seemed to reduce the arousal level of the subject. .... The most attractive compartment [of the test cage], in terms...

Sound stress and meat animals

Continuous expose to sounds over 100 dB reduced daily weight gain. However, continuous background sound [75 dB], or instrumental music increased daily weight gains in sheep.

Xenophobia among free-ranging rhesus groups in India

Xenophobia, defined as intolerance and aggression toward social strangers of the same species, is a characteristic of both captive and free-ranging groups of rhesus monkeys.

The importance of laboratory lighting as an experimental variable

The importance of light and illumination as extraneous variable is discussed. My suggestion is that the cage conditions are too crowded in our present racks, and there should be the same lighting for all cages in the bottom shelf as...

Phencyclidine sedation as a technique for handling rhesus monkeys: Effects on LH, GH, and prolactin secretion

These monkeys, however, are readily alarmed, and it may be difficult to obtain stable control levels for hormones which are easily influenced by stress.

Aggression in captive pigtail monkey groups: Effects of provision of cover

To assess the influence of provision of "cover" on aggressive behavior in captive nonhuman primate groups, concrete cylinders were introduced into rooms in which six groups of pigtail monkeys resided. Basal incidence of aggression was measure prior to introduction of...

Influence of handling and sedation on plasma cortisol in rhesus monkeys (Macaca mulatta)

The present study shows that it is possible by long-term regular training to achieve mean cortisol values which are significantly lower than in untrained or anaesthetized animals.
