Light Mineral Oil is a material generally used as an overlay covering microdrops of culture medium in petri dishes. Although Light Mineral Oil can protect the damage by oxidation in air, it can't completely protect the damage by evaporation and alteration of pH and osmolality in culture medium. To minimize the damage by evaporation and alteration of pH and osmolality, we assumed that Heavy Mineral Oil could be used as an alternative. Heavy Mineral Oil is high purity paraffin oil which has more viscosity and density than Light Mineral Oil, so it can prevent evaporation and maintain stable osmolality and pH in culture medium more than Light Mineral Oil. The objective of this study was to examine whether the effect of Heavy Mineral Oil is superior to the effect of Light Mineral Oil during in vitro cultivation of porcine oocytes. According to the data of repeated six experiments, survival and cleavage rate of porcine oocytes, and cell number of blastocysts were not significantly different between two groups. However, the in vitro development rate of porcine parthenogenetic embryo was significantly higher in Heavy Mineral Oil group than in Light Mineral Oil group (Light, 36.6% ± 3.9%; and Heavy, 52.1% ± 6.4%, p < 0.05). Thus, these results indicated that the treatment of Heavy Mineral Oil can improve the in vitro developmental capacity of porcine parthenogenetic embryos compared to Light Mineral Oil.
