The present study was carried out to examine the activation and parthenogenetic development of pig oocytes after exposure to ultrasound in sorbitol media supplemented with different concentrations of Ca<sup>2+</sup>. The activation rates (68.8-75.6%) of oocytes exposed to ultrasound in media containing 0.1-1.0 mM Ca<sup>2+</sup> were significantly (P<0.05) higher than those (54.3-58.3%) of oocytes exposed to ultrasound in media containing 0-0.05 mM Ca<sup>2+</sup>. When oocytes were exposed to ultrasound in media containing 0.1-0.5 mM Ca<sup>2+</sup>, the blastocyst formation rates (20.5-21.3%) were significantly (P<0.05) higher than those (3.3-6.0%) of oocytes exposed to ultrasound in media containing 0, 0.05 or 1.0 mM Ca<sup>2+</sup>. The results of the present study showed that the concentration of Ca<sup>2+</sup> in the medium used for exposure to ultrasound affects the activation and parthenogenetic development of pig oocytes and showed that the optimal Ca<sup>2+</sup> concentration is 0.1-0.5 mM.<br>
