Oocytes were obtained either in the growth phase of the first follicular wave from cows with synchronized oestrus or in any other phases of follicular development from cows without oestrus synchronization. The embryos were prepared by a standard procedure. The embryos were frozen, thawed and transferred to synchronized recipients. More of usable oocytes it was recovered in the growth phase as compared with the other phases of follicular development. Greater development of these oocytes resulted in more embryos for transfer and cryopreservation. Transfer of frozen-thawed and fresh embryos gave a 48.8% and 55.8% pregnancy rates in recipients, respectively." .
