This paper includes the study about early embryonic death, predisposing factors of early embryonic death and treatment. Early embryonic death refers to the fetal mortality which varies in mare and camelids but most probably not later than 50 days of gestation. This duration may be divided into very early mortality, early mortality, and late embryonic mortality. This also varies in mare and camelids. There are different embryonic, maternal, environmental/external, infectious, and noninfectious factors which lead to early embryonic loss. Diagnosis is very difficult as in most of the cases resorption of fetus occurs, but it is done using ultrasound machine. Unfortunately, there is no treatment to avoid early embryonic mortality. However, new reproductive technologies have increased the service rate in a herd, and efforts are still being made to determine the rate and frequency of camel embryonic loss.
Key words: Mortality, Economic losses, Mares, Progesterone, Corpus luteum
