Abstract
Despite extensive research on the reproductive health of domestic animals, embryonic mortality continues to be a problem that brings about significant losses for both commercial breeding and scientific research. This review paper discusses the genetic and environmental factors that affect embryo mortality rates in sheep along with the different techniques developed to overcome this issue. Additionally, one of the objectives of this study is to emphasize the importance of the use of time-lapse cinematography and color Doppler ultrasonography as quick and reliable methods for early detection of pregnancy and embryonic death.
