Effects of NMN supplementation on the development of early embryos derived from the heat-stressed porcine oocytes. A Representative images of the embryos at blastocyst stage in control, heat-stressed and NMN-supplemented groups. Scale bar, 200 μm. B The rate of blastocyst formation was recorded in control, heat-stressed and NMN-supplemented groups. Data were presented as mean value (mean ± SEM) of at least three independent experiments. **P < 0.01, ***P < 0.001
