B超监测母羊妊娠研究进展

对B超在母羊早期妊娠诊断、母羊怀胎数判定、母羊妊娠日龄预测、胎儿发育监测和胎儿性别鉴定中的应用研究进行了综述,认为超声断层扫描是目前最迅速、最安全、最直观、最有效的母羊妊娠监测手段;对腹壁探查和直肠探查结果进行的对比和总结认为,配种后50～100d是通过腹壁探查进行母羊妊娠诊断的最佳时期,配种后30～30d是通过直肠探查诊断母羊妊娠的最佳时期。

Progress in research on detecting gestation in sheep using real-time B-mode ultrasonic scanner

The review discusses diagnosing pregnancy,determining fetal numbers,estimating gestational age,decting fetal development and indentifying fetal sex as well as using real-time B-mode ultrasonic scanner to detect the uterus only in goats and sheep.It is shown that real-time B-mode ultrasonic scanning is the quickest,safest,clearest and most effective method of detecting gestation in goats and sheep at present.In addition,the results of transabdominal and transrectal scanning for detercting gestation in goats and sheep are compared and summed.It is shown that 50-100 d after mating is the best time for transabdominal and 30-50 d for transrectal.
