    Abstract: This research was conducted to determine the effect of FSH 
  made in Canada and Ningbo and the ages and weight of lamb on juvenile lamb superovulation 
  of Xinjiang Fine Wool Sheep and to compare oocyte mature time from juvenile 
  lamb superovulation and adult ewe ovary and to study the effect of oocyte mature 
  time and oocyte level on the quality of IVF. The results showed that the optimal 
  method of lamb&#146;s superovulation 
  was to inject 30 mg FSH made in Canada for four times with the interval of 12 
  h and the best maturation time of oocyte <I>in vitro</I> for cleavage was 30 
  h. The development of oocyte in different stages was not affected on cleavage. 
  This study can provide important experimental data for juvenile <I>in vitro</I> 
  embryo technology.
