Monitoring menstrual cycle, gestation and lactation by measuring urinary oestradiol and progesterone in the captive golden snub-nosed monkey (Rhinopithecus roxellanae)

The golden snub-nosed monkey is an endangered species and study of its reproductive physiology is crucial for the species’ breeding programs. Urine samples (770) from 5 mature female golden snub-nosed monkeys were collected in the Shengnongjia Nature Reserve between October 2013 and December 2014 to...

Description
Summary:The golden snub-nosed monkey is an endangered species and study of its reproductive physiology is crucial for the species’ breeding programs. Urine samples (770) from 5 mature female golden snub-nosed monkeys were collected in the Shengnongjia Nature Reserve between October 2013 and December 2014 to monitor their menstrual cycle, gestation, and lactation. The concentrations of oestradiol (E2) and progesterone (P4) in the samples were measured by Chemiluminescent Microparticle Immunoassay (CMIA), and the hormone concentrations were indexed to creatinine levels to compensate for differences in water content. The results showed that the E2 and P4 levels during the breeding season were significantly higher than those during the non-breeding season (P
