Abstract:

 The aim of the study was to investigate the effects of sodium selenite (SS) on in vitro maturation of Yanbian dairy goat oocytes and development of somatic cell nuclear transfer (SCNT). The oocytes were cultured in vitro medium supplemented with different concentrations  (0.0,2.5,5.010.0 ng·mL-1) of SS , then the oocytes maturation rate, intracellular ROS and GSH level were examined. The Yanbian dairy goat mammary gland epithelial cells were as the donor cells for SCNT. The quality and development capacity of SCNT embryos were evaluated with staining. The result showed that 5.0 ng·mL-1 SS significantly improved the oocytes maturation rate and the SCNT embryos development compentence. The treatment with 5.0 ng·mL-1 treatment was not only significantly reduced the ROS level but improved the GSH level and the blastocyst cell number. In conclusion, 5.0 ng·mL-1 SS supplementation in vitro medium can significantly improved the Yanbian dairy goat oocytes maturation rate and SCNT embryos development competence.
