Abstract

The effects of different preservation conditions (temperature 20-25 or 10-15°C; duration 12 or 24 h) for ovaries of Cervus nippon yesoensis on in vitro maturation of oocytes were examined. When ovaries were kept for 12 h at 20-25°C, maturation rate of oocytes was highest (71%); however, it declined when the preservation time was extended to 24 h (31%). When the preservation temperature decreased to 10-15°C, the maturation rate after 12 h preservation decreased (51%) but it remained in same level even though preservation time is prolonged to 24 h (55%).
