Transcriptional Complexity in Receptive and Pre-receptive Endometrium of Dairy Goat
A total of 20 healthy 24-month-old multiparous dairy goats (Xinong Saanen) were induced to estrous synchronization for this study. The first day of mating was considered to be day 0 of pregnancy. Gestational days 5 and 15 were important time points for embryo implantation in goats 105. The experimental goats were observed 3 times daily to ascertained estrous sign and mated naturally twice in estrus. And then the goats were euthanized when the goats lost consciousness caused by intravenous injection of barbiturate (30mg/kg) at gestational day 5 (pre-receptive endometrium) and gestational day 15 (receptive endometrium). Endometrium samples from 10 goats at gestational day 5 and 10 goats at gestational day 15 were obtained from the anterior wall of the uterine cavity.
