Saliva sampling to assess cortisol levels in unrestrained common marmosets and the effect of behavioral stress

We report a method for taking saliva samples from unrestrained, captive marmosets (Callithrix jacchus) to assess levels of free cortisol. Saliva samples can be obtained reliably, without any habituation, by encouraging the marmosets to lick and chew a cotton-wool bud...

Inside the monkey house

The monkeys greet our presence [reporter getting an offical tour] with alarm. We are, in truth, a frightful sight, decked out head to toe in plastic coveralls. .. But the monkeys' reaction, I sense, is not just about how we...

Urinary cortisol responses to social isolation and short-term physical restraint in the common marmoset (callithrix jacchus)

Plasma cortisol has been used to study the HPA (hypothalamic-pituitary-adrenal) axis response in primate species, however, the stress associated with handling and blood collection may confound this measure. The purpose of this study was to validate the use of urinary...

Assessment of preference for grid-flooring and sawdust-flooring by captive-bred marmosets in free-standing cages

Marmosets (Callithrix jacchus) in a captive breeding colony living in metal caging, with wooden shelves and perches, were assessed by video recording for the time spent on the floor of the cage when that floor was a wire grid above...

Stressors of common marmosets (Callithrix jacchus) in the captive environment: Effects on behaviour and cortisol levels

Salivary cortisol samples, collected using a cotton bud with banana on the tip, doubled following 30 minutes of exposure to playing radio (70-80 dB) or loud construction work (70-80 dB). Despite being sheltered from rain while outdoors, the marmosets moved...

Animal welfare and enrichment: A preference study in the common marmoset (Callithrix jacchus)

In general, the results showed that the monkeys choose much less than expected between fruits cut and presented as usual in an open dish and fruit inserted as a whole in a pointed branch. When choosing a particual enrichment, it...
