In vivo diagnosis of embryo mortality in sheep by real-time ultrasound



In vivo diagnosis of embryo mortality in sheep by real-time ultrasound



Small Ruminant Research 24(2): 141-145



Examinations of ovaries and uteri in early pregnancy by real-time ultrasound in sheep could be the base for investigations on embryo mortality in vivo. Therefore, 38 adult German Mutton Merino ewes were frequently examined by real-time ultrasound within the breeding season concerning number of corpora lutea as well as embryos. An Aloka SSD 500 ultrasound unit with a 5 MHz probe was used. The results were compared to post mortem examinations of 88 females from the same flock, also in the breeding season, 1 year before. The ovulation rate diagnosed by real-time ultrasound and after killing was 2.08 and 1.93. No differences in the level of embryo mortality occurred between the two methods (33.5% determined by ultrasound compared with 36.7% by post mortem diagnosis). In comparison to the post mortem examinations, ultrasonographic diagnosis is an alternative method to check embryonic mortality in living sheep.
