چکیده انگلیسی
Fecal reproductive progestagen monitoring in the mountain gazelle (Gazella gazella) provided a non-invasive method for tracking reproductive cycling, estimating age of sexual maturity and diagnosing pregnancy in this species of gazelle. Fresh fecal samples were collected from eight female mountain gazelle (Gazella gazella) for a period of two months. Two of the animals were pregnant while the other six were not. Using the progestagen profile the luteal phase, interluteal (follicular) phase and estrous cycle in adult female gazelles were determined to be 12.5 ± 1.2, 5.9 ± 0.59 and 18.8 ± 0.98 days respectively. Significant inter-animal differences in fecal progestagen concentration were observed in both the luteal and follicular phases. Significant differences were observed in the levels of fecal progestagen between cycling females and females in late pregnancy. Low concentrations of fecal progestagen in females aged less than 18 months old indicated that sexual maturity in captivity is not attained before that age.
