This study was evaluated, by transretal ultrasound, the embryonic-fetal development from days 15th to 45th of gestation visualizing the first signs of gestation in 60 Sant Inês ewes. The identification of the earliest and the latest parameters of evaluation were performed between days 15th to 19th (16.7 ± 1,3) of pregnancy for intra-uterine fluid, . embryonic vesicle between days 16th to 22th (18.6 ± 1.4), embryo between 18th to 26th (22.8 ± 1.9), placentoms between 20th to 29th (25.1 ± 2.0), heartbeat between days 24th to 29th (25.9 ± 1.4), amniotic membrane between 24th to 32th (27.4 ± 1.8), head and upper body differentiation between 30th to 37th (33.4 ± 2.2), fetus movement between 30th to 38th (34.2 ± 2.0), umbilical cord between 32th to 39th (35.1 ± 1.5), button of the anterior and posterior members between 34th to 39th (36.7 ± 1.5) and ocular globe between days 39th to 43th (40.9 ± 1.2). It was concluded that the first signs of gestation can be identified as soon as day 15th days of gestation. However, it is wise diagnosing pregnancy after day 24th, when it is possible to visualize the fetus and the heart beat.Downloads
