Foetal death was induced in 10 standardbred mares at day 45 of gestation by injecting 20 to 45 ml of hypertonic (24 percent W per V) saline into the conceptus at surgery. The results show that urinary and plasma oestrone sulphate concentrations rise rapidly during early pregnancy, and are associated with a viable foetus after day 45 of pregnancy.
