Estrone-conjugates (E1C) were measured in the feces of six female pygmy lorises (Nycticebus pygmaeus) during estrus (n = 12), pregnancy (n = 4) and the postpartum period (n = 3). Noninvasive feces collection permitted frequent sampling throughout estrus and pregnancy, without disturbance of animals. The estrous period was defined as an increase in fecal E1C levels above an average of 70 ng/g feces with peaks above 100 ng/g feces obtained in consecutive fecal samples collected over a 6- to 11-day period between the end of July and the first third of October. Comparison of the periovulatory profile of E1C and the stage of labial opening of the vagina revealed a high agreement (P < 0.001). In all pregnant females, an E1C rise was found approximately 47 days postestrus, the source of which may be the growing fetal placental unit. Estimated gestation lengths ranged between 187 and 198 days (n = 4).
在发情期（n = 12）、孕期（n = 4）和产后阶段（n = 3），对6只雌性倭蜂猴（Nycticebus pygmaeus）粪便中的雌酮结合物（E1C）进行了测量。非侵入性粪便采集允许在整个发情期和孕期频繁采样，而不会干扰动物。发情期定义为粪便E1C水平高于平均70 ng/g粪便，在7月底至10月上中旬的6至11天内连续采集的粪便样本中峰值高于100 ng/g粪便。E1C排卵周期特征与阴道唇张开阶段的比较显示高度一致（P < 0.001）。在所有怀孕雌性中，发情后约47天发现E1C升高，其来源可能是不断生长的胎儿胎盘单位。估计妊娠期长度在187至198天之间（n = 4）。
