The removal of large follicles 3 d after AI during induction of superovulation of cows had detrimental effects on the number of transferable and freezable embryos. The removal of large follicles 1 d after AI had no effects on embryo quality. Therefore, this procedure appears not to be beneficial in improving the numbers of embryos available for transfer following superovulation of cattle. Key words: Large follicle, aspiration, superovulation, cow
