Retention and development of eggs transferred to the uterus at various times after ovulation in the rabbit

摘要

Summary. The pattern of egg expulsion/retention was determined in rabbits 24 h after transfer of eggs to the uterus 24–84 h p.c. Nearly all eggs transferred at 24 or 36 h p.c. were expelled into the vagina but from 36 h onwards an increasing proportion was retained in utero, although maximum retention was not recorded until 76–84 h p.c.
