Abiotic environments coupled with confinement stressors can lead to psychological and physiological changes in captive golden snub-nosed monkeys (Rhinopithecus roxellana), such as stereotypic behaviors and elevated fecal cortisol levels. The Hangzhou Zoo environmental enrichment project involved seven individuals. Behavioral data were collected with an instantaneous sampling method between 08: 30-10: 30 am and 14: 00-16: 00 pm every working day from August 1st to November 1st, 2013. As a result of the enrichment, intiactive and stereotypic behaviors decreased significantly(P=0.021; P=0.034) while exploratory behaviors increased(P=0.018). After environmental enrichment was provided, golden snub-nosed monkeys tended to climb, explore and look around more often than before enrichment(P=0.012; P=0.014; P=0.010). An enzyme-linked immunoassay fecal cortisol analysis showed significantly decreased fecal cortisol levels in all but one male(P=0.028). Altogether, behavioral and endocrine results showed that the welfare of golden snub-nosed monkeys was improved after enrichment. ©, 2015, Science Press. All right reserved. Source
