The effect of culture media and mycotoxin on porcine preimplantation embryonic development has been investigated. In the first experiment, porcine embryonic cleavage rates were similar in NCSU-23 and PZM-3 culture media, while more blastocysts were produced in PZM-3 (P<0.05). BAX and BCL2L1 transcription levels were similar in blastocysts cultured in both media. Cleavage rates were significantly decreased in the presence of cycloheximide (P<0.05), and both á-amanitin and cycloheximide completely inhibited blastocyst formation. In the mycotoxin experiment, porcine embryonic cleavage rates decreased in 10 ìM á-ZEA group, while blastocyst rates decreased in 30 ìM á-ZEA group (P<0.05). Total cell numbers of blastocysts were significantly lower in the 10 µM á-ZEA group (P<0.05). The transcription levels of POU5F1 and BCL2L1 were similar, while that of BAX and the ratio of BAX/BCL2L1 significantly increased in 3 ìM and 10 ìM á-ZEA groups compared to control group.
