Figure 7From: Development to the blastocyst stage, the oxidative state, and the quality of early developmental stage of porcine embryos cultured in alteration of glucose concentrations in vitro under different oxygen tensionsNuclear DNA fragmentation indices of Day 6 porcine blastocysts developed under either 5% or 20% oxygen tensions: comparison of different culture media during the first 2 days of IVC. Within each end point, bars with different letters (a, b) are significantly different for 5% oxygen tension treatment (P < 0.05). There were no significant differences within each energy substrate supplement group across oxygen tension treatments. The numbers on the bars represent the number of embryos used for the assay.Back to article page
