title: Excretion profiles of some reproductive steroids in the faeces of captive Nepalese red panda (Ailurus fulgens fulgens).
abstract: Faecal samples were collected up to once daily from three female Nepalese red panda (Ailurus fulgens fulgens) prior to, during, and after the expected 1995 breeding season. Radioimmunoassay of faecal progestins and oestrogens showed hormone profiles that suggest that this species is a seasonally polyoestrous, induced ovulator. Examination of faecal extracts following high pressure liquid chromatography and using antisera of high specificity, demonstrated at least five faecal progestins but only one major oestrogen, probably oestradiol. Samples from males were collected up to once weekly during the breeding season in 1996, and androgens measured by radioimmunoassay. Faecal androgens fluctuated widely for all males.
