In this study 33 New Zealand White does and 2 bucks were used. After induction Of Ovulation by human chorionic gonadotrophin (hCG) injection, oocytes were collected by flushing of oviduct. Oocytes and spermatozoa were incubated for 5 hours in Modifie Defined Medium (mDM) for fertilization and cultured in Ham's F-10 medium supplemented with 20 % Fetal Calf Serum (FCS) and 20 % Rabbit Serum (RS) for 18-21 hours, to evaluate the effect of serum in fertilization. Fertilization was assessed by detection of oocytes cleavage rates. The fertilization rates were recorded as 70.4 %, 73.8 %, 60.6 % in oocytes incubated in culture mediums with FCS or RS or without any serum respectively (p>0.05). Data were evaluated via Chi-square test. These data suggest that the differences between group averages were not statistically significant, although the fertilization rate in Ham's F-10 with rabbit serum was higher.
