Abstract: EGF and bFGF were added into the culture medium in the different stages. We studied the effects of epidermal growth factor or bisac fibroblast growth factor on the development of porcine parthenogenetic embryos in vitro. The results as follows: The addition of EGF significantly enhanced the cleavage rate of porcine parthenogenetic embryos (P<0.05); The addition of EGF or bFGF significantly enhanced the rates of blastocysts formation of 2-4cell porcine parthenogenetic embryos (P<0.05); Additionally, bFGF had more numbers of blastocysts and higher rates of blastocysts formation than the EGF’s and the control. In conclusion, EGF and bFGF are propitious to the development of porcine parthenogenetic embryos in vitro. And bFGF increased the quality of blastocysts by increasing total cell numbers in porcine parthenogenetic embryos.
