The objective of this study was to determine the development potential and quality of in vitro produced bovine embryos cultured individually or in groups. After IVM and IVF, presumptive zygotes were cultured in groups or individually, either in drops or in the modified well of the well (mWOW) system. In Experiment 1, four culture systems were utilized: T1: drop in group (control); T2: mWOW in groups; T3: mWOW individually; and T4: drop individually. Cleavage and blastocyst rates at Days 6, 7 and 8 and total cell number of Day 6 blastocysts were similar (P > 0.05) for all treatments. However, in Day 7 blastocysts, total cell number was lower (P < 0.05) in embryos cultured individually in a small drop than those cultured in the mWOW. In Experiment 2, blastocysts of T1, T2 and T3 were allocated into two groups, control and vitrified. After warming, the vitrified embryos were cultured for 72 h. At 48 h, the development of the Days 6 and 7 embryos was similar (P > 0.05) for all treatments in the control group. For the vitrified embryos, lower hatching rates (P < 0.05) were observed in the T3 group. In conclusion, embryos cultured in groups in the mWOW system had the same blastocyst rates but better quality (measured by their survival after vitrification) than those cultured individually in the mWOW system.
