The effects of repeated superovulation in 9 Chinese Holstein cows were studied in 6-superovulation experiment were conducted from Dec.2003 to Apr.2005.The result showed that 292 available embryos were obtained from 47 times,and the average number of available embryos per cow was(6.2).The available embryos were 49,50,46,48,55 and 44 in different groups.There was no decreasing trend in the number of available embryos among groups.It was suggested that the repetitious superovulation at a 3-month interval have no effect on the number of available embryos of Chinese Holstein cow.
