Abstract

In vitro development of goat embryos obtained by fertilizing oocytes using intracytoplasmic sperm injection (ICSI) was investigated. The results showed that the blastocyst rate was significantly higher (P<0.05) when the embryos were co-cultured with granular cells (GCs) in media CR1aa supplemented with 10% bovine follicular fluid (BFF) (22.2%) than with 5% (13.1%) and 15% BFF (2.7%). When embryos were co-cultured with GCs in SOFaa media, the highest blastocyst rate was obtained from supplementation with 10% BFF (25.1%), which was significantly different from 5% (12.9%) and 15% BFF (3.0%) groups. When 10% BFF and fetus bovine serum (FBS) were added into CR1aa or SOFaa media, the goat ICSI blastocyst rates were 22.6 and 26.9% or 5.8 and 6.1% respectively. These results suggest that both CR1aa and SOFaa could be used as culture media for goat ICSI embryos, 10% BFF could significantly increase the blastocyst rate and BFF was more efficient than FBS for the early in vitro development of goat ICSI embryos.
