“…It has been found that GnRH administration during the diestrous phase (5–7 days post AI) can increase the proportion of cows with an additional CL, which enhances embryo survival [ 54 ]. Similar results were observed when GnRH was administered between the 7th and 14th days after AI in dairy cows [ 55 ] and lactating buffaloes [ 56 ]. Previous research suggested that GnRH administration on day 12 of the previous cycle improves ovulation and conception rates compared to the control group, and it significantly increases P 4 concentrations in pregnant cows on day 22 [ 57 ].…”

The administration of GnRH and its agonists benefits various aspects of bovine reproductive programs, encompassing physiological stages such as estrous synchronization, post-insemination, pregnancy, and the postpartum period. The positive impact of GnRH administration in overcoming challenges like repeat breeder cows, early embryonic loss prevention, and the management of cystic ovarian disease (COD) is thoroughly surveyed. Furthermore, this review focuses on the significance of GnRH administration during the postpartum period, its role in ovulation induction, and how it enhances the productivity of embryo transfer (ET) programs. An emerging feature of this field is introduced, focusing on nano-drug delivery systems for GnRH agonists, and the potential benefits that may arise from such advancements are highlighted. While this review offers valuable insights into various applications of GnRH in bovine reproduction, it emphasizes the crucial need for further research and development in this field to advance reproductive efficiency and health management in dairy cattle.
