Abstract:

The study of luteal function in dairy cows is of great importance for improving reproductive efficiency. In recent years, despite advancements in dairy production technology, pregnancy rates remain limited by factors such as embryo loss and luteal insufficiency. As a critical temporary organ for pregnancy maintenance, the function of the corpus luteum directly affects reproductive outcomes. An in-depth understanding of the physiological characteristics, formation, and degradation mechanisms of the corpus luteum is essential for reproductive management in dairy cows. This review summarizes the mechanisms of corpus luteum formation and degradation, internal and external factors influencing its function, and related interventions, with a focus on the application of hormonal regulation and biotechnology in maintaining luteal function. The aim is to provide theoretical insights for improving corpus luteum function and enhancing reproductive efficiency.

Key words: corpus luteum, progesterone, prostaglandins, interferon, embryo loss
