Table 1. Efficiencies of DEM-assisted and mechanical enucleation of porcine oocytes, and the in vitro pre-implantation development of embryos produced from these oocytes.
Enucleationmethod | No. ofoocytes | No. of enucleatedoocytes (%) | No. of SCNTembryos | No. of 2–4-cellembryos (%) | No. ofblastocysts (%) |
DEM-assisted | 182 | 179 (98.3)b | 93 | 75 (80.6)a | 15 (16.2)a |
Mechanical | 176 | 134 (76.1)a | 85 | 67 (78.8)a | 12 (14.1)a |
Values with different superscripts within the same column are significantly different (P<0.05).
