seasonal influence on the developmental ability of porcine embryos was studied by comparisons of the number of cumulus-oocytes-complexes (COCs) per ovary pair and meiotic maturation ability of oocytes in different seasons; and by the observations on developmental competence of the parthenogenetic oocytes and cloned embryos collected from different seasons. We found that the number of COCs per ovary pairs was significantly higher in spring compared to the other seasons (Psignificant difference was found in the rate of oocytes progressing to MⅡ in four seasons (Pstocyst formation of parthenogenetic embryos in summer was obviously declined compared to the other seasons (Psed blastocyst rate of cloned porcine embryos was found in spring compared to autumn and winter (Psults suggest that there should be a seasonal influence on the developmental competence of porcine embryos.
