Fatty acids are not only widely known as energy sources, but also play important roles in many metabolic pathways. The significance of fatty acids in modulating the reproductive potential of livestock has received greater recognition in recent years. Functional fatty acids and their metabolites improve follicular development, oocyte maturation and embryo development, as well as endometrial receptivity and placental vascular development, through enhancing energy supply and precursors for the synthesis of their productive hormones, such as steroid hormones and prostaglandins. However, many studies are focused on the impacts of individual functional fatty acids in the reproductive cycle, lacking studies involved in deeper mechanisms and optimal fatty acid requirements for specific physiological stages. Therefore, an overall consideration of the combination and synergy of functional fatty acids and the establishment of optimal fatty acid requirement for specific stages is needed to improve reproductive potential in livestock.
脂肪酸不仅作为能量来源广为人知，而且在许多代谢途径中发挥着重要作用。近年来，脂肪酸在调节家畜繁殖潜力方面的重要性得到了更多认可。功能性脂肪酸及其代谢产物通过增加能量供应以及合成其生殖激素（如类固醇激素和前列腺素）的前体，改善卵泡发育、卵母细胞成熟和胚胎发育，以及子宫内膜容受性和胎盘血管发育。然而，许多研究集中于单个功能性脂肪酸在生殖周期中的影响，缺乏对更深层次机制以及特定生理阶段最佳脂肪酸需求的研究。因此，需要综合考虑功能性脂肪酸的组合与协同作用，并确定特定阶段的最佳脂肪酸需求量，以提高家畜的繁殖潜力。
