This paper systematically elaborated on the definition,occurrence patterns,and influencing factors of early embryonic loss,including embryo quality,maternal physiological status,and environmental management. Embryonic loss is closely associated with genetic defects,gamete quality,endocrine disorders,diseases,and heat stress. In response to these factors,this paper proposed comprehensive preventive measures,such as optimizing genetic selection,strengthening nutritional management,disease prevention and control,and reproductive technology interventions. Through scientific management,the rate of early embryonic loss can be effectively reduced,thereby improving the economic efficiency of dairy farming., authors=GU Sukun¹, WANG Zhencheng², LI Zhijia¹, ZHAO Shanjiang³, ZHU Huabin³, ZHAO Huiqiu^1,*, authorsList=GU Sukun, WANG Zhencheng, LI Zhijia, ZHAO Shanjiang, ZHU Huabin, ZHAO Huiqiu, authorCompany=1 Hebei Provincial Animal Husbandry Station,Shijiazhuang Hebei 050035;
