Resolving issues of psychological well-being and management of laboratory nonhuman primates

The survey indicated that approximately 83% of adult captive primates at NIH are caged alone. As only 9% of scientists interviewed currently train their animals to go into tansport cages, the majority use squeeze panels to transfer animals or to...

The effect of a sudden change in floor type on pecking behaviour in chicks

Feather pecking is to be considered as redirected ground pecking. Slatted floors appear to contribute to feather pecking. Floors without litter appear to stimulate feather pecking or, in other words, the redirection of ground pecking. .. In order to prevent...

Functional aspects of reconciliation among captive long-tailed macaques (Macaca fascicularis)

After an agonistic conflict between two animals, they may exchange affiliative social contacts. The function of this reconciliation behavior is thought to be the repair of the social relationship between the two opponents. We examined the hypothesis that reconciliation is...

Neighbour effects and the stress of tethering in sows

Repetitive behaviour of newly tethered gilts correlated positively with that of their neighbours. .. The data suggested that behaviour of neighbours was not just being copied, but itself produced stress, and it seems likely that the noise of chain chewing...

The effects of brief manual restraint, prior conditioning and Ketamine sedation on luteinizing hormone and estradiol levels in the female Bolivian squirrel monkey

No effects of conditioning - daily manual restraint suitable for blood drawing - on estrogen levels were observed. Ketamine sedation appeared to elevate estrogen and LH levels in some animals, suggesting complex side effects that may interfere with studies of...
