This study tested whether embryo development yield using in vitro fertilization (IVF) could be improved by rocking cultures. Bovine ovaries were obtained at a slaughterhouse and transported to the laboratory within 6 h. Cumulus–oocyte complexes were collected and 20–25 were transferred in 100-μL drops of TCM-199 containing 10% fetal bovine serum and antibiotics under paraffin oil. Maturation was for 20–24 h at 38.5°C under 5% CO2 and 95% air in a humid atmosphere (IVM). In vitro fertilization was carried out for 6 h using frozen–thawed sperm from a single bull in modified Brackett and Oliphant (BO) medium. Presumptive zygotes were cultured in CR1aa supplemented with 10 mg mL–1 of BSA or 5% FBS for 9 d at 38.5°C under 5% CO2, 5% O2, and 90% N2 in a humid atmosphere (IVC). Rocking was performed to a height of 6 cm every 7 s using a Profile Rocker (New Brunswick Scientific Co., Edison, NJ, USA) in an incubator. Dishes were placed at a 15-cm distance from the fulcrum of the rocker. The conventional method (no rocking) served as a control, and every experiment was replicated 3 times. For Experiment 1, the effect of the period of rocking on developmental competence was examined when COC or zygotes were subjected to rocking for IVM, IVF, or IVC (IVM-move, IVF-move, and IVC-move). There were no significant differences in rates of oocyte maturation, cleavage, and development for IVM-move v. the control, or for rate of development between IVC-move and the control. However, the rate of fertilization for IVF-move was higher than that of the control (88.9 v. 67.5%; P < 0.01), and the rate of development was higher for IVF-move than for the control (39.0 v. 25.7%; P < 0.05). For Experiment 2, the effect of rocking frequency during IVF on development was determined. The IVF cultures were rocked every 7, 3.5, and 1.5 s (IVF-1move, IVF-2move, IVF-3move). The rates of cleavage on IVF-1move, IVF-2move, IVF-3move, and the control were 74.3, 69.8, 68.8, and 60.4%, and the rates of development were 39.0, 48.3, 26.2, and 25.7%, respectively. The rates of development on IVF-1move and IVF-2move were significantly different from the control and IVF-3move (P < 0.01). These results showed that rocking during IVF improved fertilization and embryo yield, and that frequency of rocking affected embryo development.
