Abstract: We investigated the effects of astaxanthin (Ax) on the accumulation of reactive oxygen spices (ROS) and mitochondrial activity in bovine oocytes during individual maturational culture. Oocytes were cultured individually for 22 h in multi-well plates with or without 500 ng/ml Ax. After maturational culture, ROS accumulation of oocytes was lower in Ax-treated oocytes than in non-treated oocytes (P < 0.05). Mitochondrial activity was higher in Ax-treated oocytes than in non-treated oocytes (P < 0.05). The development of blastocysts in the Ax-treated oocytes tended to be higher than in non-treated oocytes (P = 0.06). These results indicate that Ax treatment improves the developmental competence of bovine oocytes, maybe due to the reduction of ROS accumulation and the improvement of mitochondrial activity.
