Embryo loss occurs when there is death of embryos followed by absorption, or expulsion. Healthy embryos grow into foetuses. There is often alarm when an abortion is seen but it should be remembered that there can be loss of embryos at any time during early pregnancy, which often go unseen. During the period of maturation, which results in premature farrowings. It can be seen therefore that losses can take place at any stage from approximately 14 days after mating, when implantation has taken place, through to 110 days of pregnancy.
