| Abstract: | Background There is a concern about conservation of endangered species today. Among this species, the Leontopithecus (Lesson, 1840) is outstanding. Its population has been whirling reduced. So far the reproductive physiology of Leontopithecus has few studies, it is fundamental requisite to preserve this species. Obstetric sonography has become an essential method in reproductive management of primates. Method This method is very helpful to detect early pregnancy and evaluate some deficiency of fetal growth. In this study, 14 pregnancies were monitored using real‐time abdominal sonography. During each evaluation, the number of fetus was recorded, gestational sac and heart beats were observed, and biparietal diameter was measured. Results The results showed that abdominal sonography is a reliable method for observation of gross morphological changes during pre‐natal development and to estimate gestational age. No statistically differences were observed between twins and singletons. This study is the first investigation of pre‐natal growth in Leontopithecus. |
