摘　　要：为研究排卵延迟奶牛发情配种后黄体的变化规律及其差异性,本研究在临床症状观察、直肠检查和B超辅助检查诊断的基础上,选取8头排卵延迟奶牛（排卵延迟组）、5头健康正常发情奶牛（对照组）,应用B超对黄体的相关指标（直径、面积、周长和体积）进行了测量及分析,对获得的不同阶段典型黄体声像图进行了描述。结果显示,与对照组相比,排卵延迟组与对照组奶牛黄体的直径、面积、周长和体积在发情配种后7～15d差异均不显著（P〉0.05）。在发情配种后第9和13天排卵延迟组奶牛黄体相关指标（直径、体积、面积和周长）大于对照组奶牛,而在第11天小于对照组奶牛。结果表明,排卵延迟奶牛发情后不同阶段B超黄体直径、面积、周长和体积与正常发情排卵后的相应指标没有显著差别。The study was aimed to observe the variation and differences of corpus luteum of delayed ovulation cows after estrus.Based on the observation of clinical symptoms,rectal examination and diagnosis of B-ultrasound scanning,8delayed ovulation dairy cows with the variation（delayed ovulation group）and 5healthy and normal dairy cows with estrus（control group）were selected,and the related indicators of the corpus luteum（diameter,area,perimeter and volume）were measured by B-ultrasound scanning.These luteal indicators were compared and analyzed further,and the luteal typical sonography obtained of the different stages were described.The results showed that the diameter,area,perimeter and volume during 7to 15 dafter estrus of the corpus luteum had no significant differences between delayed ovulation group and control group（P〉0.05）.However,on the 9th and 13 th day after estrus,the luteal relevant indicators of delayed ovulation group cows（diameter,volume,area and perimeter）were greater than that of control group cows and less than normal dairy cows on the 11 th day.There were no significant differences in diameter,area,circumference and volume of corpus luteum at the different stages after estrus between the delayed ovulation dairy cows and the normal ones.
