Knowledge of the reproductive biology is critical for the development of management strategies of the species both in captivity and in the wild, and to address conservation concerns regarding the sustainable use of a species. The present report characterizes some aspects of the reproductive biology of the wild red brocket deer inhabiting the North-eastern Peruvian Amazon region, based on the anatomical and histological examination of the female reproductive organs of 89 wild adult females in different reproductive states. The red brocket deer female presented ovarian follicular waves involving the synchronous growth of a cohort of an average 25 follicles but only one follicle generally survived and continued development, reaching maturity at 4mm. Mean ovulation rate was 1.14 and litter size was 1 fetus. Females presented a low rate of reproductive wastage of 14.3% of embryos. Among the 89 adult females studied, 41 (46.1%) were pregnant and 48 (53.9%) were non-pregnant females. In the Northeastern Peruvian Amazon, conceptions occurred year-round in the red brocket deer but there were peaks in the rate of conception. Estimated yearly reproductive production was 0.76-0.82 young per adult female. Most pregnant females in advanced stage of pregnancy had at least one active CL, suggesting the persistence of CL throughout gestation.
生殖生物学知识对于圈养和野外物种管理策略的制定至关重要，也有助于解决关于物种可持续利用的保护问题。本报告根据对 89 只处于不同繁殖状态的野生成年雌性动物的雌性生殖器官的解剖和组织学检查，描述了生活在秘鲁东北部亚马逊地区的野生红麂的一些生殖生物学特征。红麂雌性动物表现出卵巢卵泡波，涉及一群平均 25 个卵泡的同步生长，但只有一个卵泡通常存活并继续发育，达到 4 毫米时成熟。平均排卵率为 1.14，胎仔数为 1。胚胎的生殖损耗率较低，为 14.3%。在所研究的 89 只成年雌性中，41 只（46.1%）为怀孕雌性，48 只（53.9%）为非怀孕雌性。在秘鲁东北部亚马逊地区，红麂全年都有受孕现象，但受孕率有高峰。估计每年的生殖产量为每只成年雌性 0.76-0.82 只幼仔。处于妊娠晚期的大多数怀孕雌性至少有一个活跃的黄体，这表明黄体在整个妊娠期内持续存在。
