The Ultrasonic Examination of Ovaries as a Tool in Goat Superovaluation Procedures

The aim of this research was to establish the importance and accuracy of the ultrasonic examination of donor goats submitted to superovulation procedures. For this reason 9 goats were systematically examined by ultrasound: 1) to monitor development of the follicles on the ovaries after hormonal treatement started ; 2) to confirm the ovulation(s) and 3) to assess the quality of the corpus/ora luteum/ea (CL) on the respective ovaries. To perform the ultrasonic examination the animals were placed in dorsal recumbency and 7, 5MHz ultrasound probe was placed into the rectum. The accuracy of the ultrasound exams was measured by comparing the number of follicles counted on ovaries with number of corpora lutea presented after laparatomy was done to accomplish the lavage of uterus and collection of the 7 days old embryos. The absence of follicle(s) on ovaries after ovulation was expected and does mated was considered as a sign of occured ovulation. The rate of follicles found on the ovaries by ultrasound / number of corpora lutea counted when the uterus was rinsed was 57, 86%. If there were less then 10 follicles per ovary the results were even better. The ultrasonic exams of donor goats is appreciable tool by which follicular dynamics can be followed and the success of superovulation procedure predicted and measured.
