Abstract: The superovulated donors of white cashmere goat were artificially inseminated (AI) with frozen sexed Xsemen to produce gender preselected embryos, then performed fresh embryo transfer. Results: ①The average numbers of ovum collection from the group of AI with frozen sorted semen and the group of fresh unsorted semen were 13.3 and 12.5 respectively. The rates of fertilization of these two groups were 29.6%(55/186) and 94.0% (281/299), the former was significantly lower than the latter(P<0.01). ②The lambing rates of gender preselected embryos transferring and untreated embryos transferring were 42.2% and 58.1% respectively. There was significant difference between the two groups (P<0.01). ③The rate of correct offspring in gender preselected embryos transfer group was 100%, which was significantly higher than untreated groups’57.4%(P<0.01). The results was proved the feasibility of gender preselection in offspring of white cashmere goat by sorted X and Ysperm, artificial insemination to produce embryos, and embryo transfer to obtain the kidlets.
