Lipids and oils are the primary sources of monounsaturated and polyunsaturated fatty acids (MUFA and PUFA), which are necessary for human and animal health. Omega-3 and omega-6 are essential nutrients for broilers. Omega-6 members, such as linolenic acid, are essential for broilers and must be obtained through feed. Vegetable oils are the primary source of omega-6 added to broiler feeds. Unsaturated fatty acids are better digested and absorbed than saturated fatty acids and generate more energy at a lower cost, boosting productivity. Feeding supplements with omega-6 can increase the fatty acid content in meat and increase weight, carcass, viscera, and FCR. The quality of meat taste and antioxidant content was also improved after giving omega-6 and influencing mineral metabolism. Broiler reproductive performance is also enhanced by reducing late embryonic mortality, hence enhancing fertility, hatchability, sperm quality, and sperm quantity. Meanwhile, for broiler health, omega-6 can lower cholesterol levels, triglycerides, very low-density lipoprotein, and low-density lipoprotein. It also supports support for T-helper cell (TH)-2-like IgG titers, increasing prostaglandins, eicosanoids, and antioxidants. In addition, it also supports anti-inflammation. Other researchers have extensively researched and reviewed studies on the effects of omega-6 on poultry. Meanwhile, in this review, we provide new findings to complement previous studies. However, further studies regarding the effects of omega-6 on other poultry are needed to determine the performance of omega-6 more broadly.
脂质和油类是单不饱和脂肪酸和多不饱和脂肪酸（MUFA和PUFA）的主要来源，而这些脂肪酸对人类和动物的健康至关重要。ω-3和ω-6是肉鸡的必需营养素。ω-6族成员，如亚油酸，对肉鸡来说是必需的，必须通过饲料获取。植物油是添加到肉鸡饲料中的ω-6的主要来源。不饱和脂肪酸比饱和脂肪酸更易被消化和吸收，能以更低成本产生更多能量，提高生产性能。添加ω-6的饲料补充剂可增加肉中的脂肪酸含量，增加体重、胴体、内脏重量并改善饲料转化率。给予ω-6后，肉的口感质量和抗氧化剂含量也得到改善，并影响矿物质代谢。降低胚胎后期死亡率还可提高肉鸡繁殖性能，从而提高受精率、孵化率、精子质量和精子数量。同时，对肉鸡健康而言，ω-6可降低胆固醇水平、甘油三酯、极低密度脂蛋白和低密度脂蛋白。它还支持辅助性T细胞（TH）-2样IgG滴度，增加前列腺素、类二十烷酸和抗氧化剂。此外，它还支持抗炎作用。其他研究人员已对ω-6对家禽的影响进行了广泛研究和综述。同时，在本综述中，我们提供新的研究结果以补充先前的研究。然而，需要进一步研究ω-6对其他家禽的影响，以便更全面地确定ω-6的性能。
