Fecal progesterone, estrogen, and androgen metabolites for noninvasive monitoring of reproductive function in the female Indian rhinoceros, Rhinoceros unicornis.
This investigation aimed to establish noninvasive methods for endocrine monitoring of estrous cycles and pregnancy in the Indian rhinoceros. Fecal samples were collected 1-3 times per week from nonpregnant and pregnant captive females (n = 7). Enzyme immunoassays for fecal progesterone, androgen, and estrogen metabolites, respectively, were tested for their ability to determine follicular and l...
متن کاملLongitudinal fecal hormone analysis for monitoring reproductive activity in the female polar bear (Ursus maritimus).
The objective was to identify suitable enzyme immunoassays to monitor gonadal and placental function in the female polar bear. Immunoreactive progesterone, progesterone metabolite (PdG), estrogen, and androgen metabolite (T) concentrations were measured in fecal samples collected over 24 mo from captive female bears (N = 20). Whereas fecal extracts produced displacement curves parallel to the s...

متن کاملCurrent Status and Future Prospects for Reproductive Technologies in Small Ruminants
INTRODUCTION Reproductive technologies such as artificial insemination (AI) and multiple ovulation and embryo transfer (MOET) have been technically feasible and commercially utilized in small ruminants for many years (reviewed by Betteridge 1981; Evans 1991; Salamon and Maxwell 2000). Sheep and goats are major contributors to the domestic economy of many nations, but neither AI nor MOET has bee...
