ABSTRACT

The aim of the study was to compare the effectiveness of pregnancy diagnostics in sheep and the diagnosis of the number of embryos on the basis of two ultrasound methods: trans rectum in sheep lying in the dorsal position (with a Pie Medical Scanner 100LC apparatus equipped with a 8 MHz probe) and trans cutem in standing sheep (with an Aloka SSD210DXII apparatus with a 3.5 MHz probe). The transrectal ultrasound examination made it possible to positively diagnose pregnancy in 89% ewes as early as 16 days after service, while a definite confirmation of pregnancy in all examined sheep was possible on day 19. In contrast, the diagnosis of pregnancy in all examined sheep via abdominal integuments was possible only on day 41 of pregnancy. The determination of the number of developing embryos in case of twin pregnancy with the trans rectum method was possible as early as day 22 after service (83%), and on day 27 the accuracy of diagnosis increased to 92%. In case of the transcutaneous examination the accuracy of assessment of the number of embryos was much lower, amounting to 33 on day 27% of pregnancy and maximum 83 on day 41%.

Key words: pregnancy diagnosis, sheep, ultrasound.
