This study evaluated colour-Doppler ultrasound imaging (UI) as a substitute for laparoscopy to count the corpora lutea (CL) in superovulated sheep. Twenty-five Santa Ines ewes were superovulated three times at 21-day intervals. Corpora lutea were counted by colour-Doppler UI (CL ) 6 days after each superovulation and confirmed by laparoscopy (CL ) 12 hr later. The mean number of CL was similar for both techniques (2.1 ± 2.5 vs. 2.1 ± 2.7 for CL and CL , respectively) with a significant positive correlation (r = .94; r =.89). Colour-Doppler UI effectively evaluated the ovarian response in superovulated ewes and efficiently identified animals that did not respond to superovulation.
本研究评估了彩色多普勒超声成像（UI）作为腹腔镜检查的替代方法，用于计数超排绵羊的黄体（CL）。25只圣伊内斯母羊每隔21天进行3次超排。每次超排后6天通过彩色多普勒UI计数黄体（CL ），12小时后通过腹腔镜检查进行确认（CL ）。两种技术的CL平均数量相似（CL 和CL 分别为2.1±2.5和2.1±2.7），具有显著的正相关（r = 0.94；r = 0.89）。彩色多普勒UI有效地评估了超排母羊的卵巢反应，并有效地识别出对超排无反应的动物。
