The objective of our study was to determine the effects of FSH superstimulation on the number of aspirated follicles and collected oocytes in dairy cows during two consequent follicular waves after treatment. Twelve unpregnant cows were used. The cows bearing corpus luteum were synchronized by PGF2alpha (day 0) and they were treated by FSH in 12 h intervals on days 12, 13, and 14. Transvaginal ultrasonographic puncture of oocytes was performed on days 7, 10, 16, and 20. The results showed that administration of FSH increased the number of follicles and the number of collected oocytes in the growing phase of the 1st follicular wave after superstimulation, nevertheless a higher number of follicles and a higher recovery rate of oocytes can be expected in the growing phase of the 2nd follicular wave after superstimulation as well.
