摘要
天然抗氧化剂是指从天然产物中提取的具有抗氧化能力的活性物质,因其具有清除或抑制氧自由基的生物学特性,故常常被用作食品添加剂。近年研究发现,天然抗氧化物有缓解机体氧化损伤和保护内脏器官的功效,对老化蛋禽卵巢中卵泡发育和肝脏产生的卵黄前体物存在一定的调节作用。本文围绕蛋鸡“肝脏-血液-卵巢信号轴”的产蛋机制,综述了各类天然抗氧化剂通过调节衰老蛋鸡抗氧化水平,进而对卵黄前体物合成能力产生影响,以期为维持蛋鸡的高产水平提供思路与方向。
Natural antioxidants are bioactive substances with antioxidant capacity extracted from natural products, which are often used as food additives due of their biological properties of scavenging or inhibiting oxygen free radicals. Recent studies have found that natural antioxidants have the ability to mitigate oxidative damage and protect internal organs, and have a moderating effect on follicular development in the ovaries and yolk precursors produced in the liver of aging birds. This paper focuses on the egg production mechanism of the "liver-blood-ovary signal axis" in laying hens, and reviews the effects of these various natural antioxidants on the synthesis of yolk precursors by regulating the antioxidant levels in aging hens, with a view to provide ideas and directions for maintaining the high egg production levels in laying hens.
