Sažetak
The aim of research was to establish the importance and accuracy of the ultrasonic examination of donor and recipient goats submitted to assisted reproduction procedures. For this reason, 17 donor goats were systematically examined by ultrasound to count the preovulatory follicles (≥ 5 mm) at observed oestrus onset and to confirm occurred ovulation(s). The accuracy of ultrasound exams was measured comparing previous findings with number of corpora lutea (CLs) present when flushing was performed. On the other hand, 14 recipient goat ovaries were monitored by ultrasound to assess: the number of dominant follicles (≥ 5 mm) present during oestrus, occurred ovulation as well as echogenic quality of CLs before semylaparoscopic embryotransfer was carried out. The total relative undervalue of ultrasound prediction of ovulation was found to be 38.37 %. The response of 9 out of 14 (64 %) recipient goats, after standard hormonal protocol was applied, was adequate, what means that at most two dominant follicles, timely occurred ovulation and good echogenic quality of respective CLs was found. The ultrasonic examination of donor and recipient goats is appreciable tool to follow up follicular dynamics, success of superovulation procedures and to confirm the ovulation and echogenic CLs quality, as well as to predict the ovulatory rate.
