Following insemination, reproductive failure in cattle is largely manifested as embryo mortality and is a major source of financial loss to livestock producers. Ongoing studies at this laboratory into factors affecting embryo mortality have facilitated the collection of new data on the extent and timing of embryo and foetal mortality in cattle. Oestrus was synchronised in 158 beef cross heifers and following artificial insemination, embryo and foetal survival rates were determined on days 14 and 30 after insemination and subsequently at calving. Embryo survival rates measured on days 14, 30 and at full term were similar at 68%, 76% and 71.8%, respectively (P0.05). Based on morphological examination, all the 14-day-old embryos recovered were assessed as grade 1. These results provide new information indicating that most embryo losses in heifers have occurred before day 14 after insemination.
