Gynecological and obstetrical ultrasonography has become an indispensable tool in the routine management, health evaluation and research on captive non-human primates.
Ultrasound was used to evaluate the uterus and estimate the gestation of owl monkeys. Twelve couples were selected, where five were primiparous and seven multiparous females from the National Primate Center reproductive colony, Ananindeua-PA, Brazil. The procedures were carried out using the GE Logiq 100 MP, equipped with a 7.5 MHz linear probe.
The females showed a simple uterus, of elongated shape, regular outline and homogeneous echogenic texture. In the uterine measurements craniocaudal diameter, dorsoventral diameter and uterine volume (UV), significant differences were identified (P < 0.05) between ultrasound examinations of primiparous and multiparous females. The UV showed a positive correlation with the number of births. The gestational sac and the embryonic echo were visible between 28 and 38 days after mating. Between 48 and 68 days after mating, embryonic death was identified in all the gestations.
The chemical (use of tranquilizers) and husbandry factors (capture stress) may be related to the prenatal death. The establishing methods of conditioning the female to the ultrasonographic exam may offer a solution to this problem.
妇产科超声检查已成为圈养非人灵长类动物日常管理、健康评估和研究中不可或缺的工具。
使用超声评估夜猴的子宫并估计其妊娠情况。从巴西阿纳尼德乌阿-帕拉州国家灵长类动物中心繁殖群体中选取了12对夜猴，其中5只为初产雌性，7只为经产雌性。使用配备7.5 MHz线性探头的GE Logiq 100 MP超声仪进行检查。
雌性夜猴显示为单子宫，形状细长，轮廓规则，回声质地均匀。在子宫的头腹径、背腹径和子宫体积（UV）测量中，初产和经产雌性的超声检查结果存在显著差异（P < 0.05）。子宫体积与分娩次数呈正相关。交配后28至38天可见妊娠囊和胚胎回声。交配后48至68天，所有妊娠均出现胚胎死亡。
化学因素（使用镇静剂）和饲养因素（捕捉应激）可能与产前死亡有关。建立使雌性适应超声检查的方法可能为解决这一问题提供方案。
