Abstract：Early embryonic lossin cattle，as a major challenge in the cattle industry，has attracted extensive research attention in recent years and achieved significant progress. Studies have revealed that genetic factors， environmental factors （such as heat stress and nutritional imbalance），management negligence，and infectious pathogens are al factors contributing to early embryonic loss in cattle. To address this issue，researchers have proposed comprehensive prevention and control strategies including optimizing nutritional supply，reducing environmental stress，and strengthening disease prevention and control. Meanwhile，the innovation of modern biotechnology has opened up new avenues for in-depth exploration of the complex mechanisms of early embryonic loss in cattle. In the future，research in this field willfocus on further revealing the mechanisms of embryonic loss，improving the precision and effectiveness of prevention and control technologies，and thus providing a solid guarantee for the sustainable development of the catle industry.
