Enrichment of broiler meat with very long-chain omega-3 fatty acids (VLCn-3 FA) is of interest because of their beneficial effects on human health. The ability of Ahiflower® (AHI) oil (Buglossoides arvensis), which naturally contains stearidonic acid (SDA), and a high-alpha-linolenic acid (ALA) flaxseed (FLAX) oil to enrich VLCn-3 FA contents in broilers tissues was investigated. Fifty-five Cobb 500 chicks were fed from days 12 to 35 of life either a control (CON) diet that contained 27.9 g/kg soybean oil or AHI or FLAX oils, each individually at 7.5 or 22.5 g/kg of the diet in substitution for soybean oil (all on an as fed basis). Total VLCn-3 FA contents were greater in breast, thigh, liver, adipose tissue, and plasma of all n-3 treatments compared to CON, with the greatest increase observed at the highest level of AHI and FLAX oils (p < 0.001). AHI oil at 7.5 g/kg promoted the most efficient synthesis and deposition of VLCn-3 in broiler tissues measured as deposition of VLCn-3 FA in tissues relative to intake of n3 FA. In conclusion, both ALA and SDA oils increased VLCn-3 FA deposition in tissues, but there were diminishing returns when increasing dietary levels of the oils.
富含非常长链ω-3 脂肪酸（VLCn-3FA）的肉鸡肉引起了人们的兴趣，因为它们对人类健康有益。Buglossoides arvensis 油（AHI）和高α-亚麻酸（ALA）亚麻籽油具有将 VLCn-3FA 含量富集到肉鸡组织中的能力，因此研究了这两种油。55 只 Cobb 500 小鸡从第 12 天到第 35 天的生命期内，分别喂食对照（CON）饮食（含有 27.9g/kg 大豆油）、AHI 或 FLAX 油，每个饮食中分别用 7.5 或 22.5g/kg 的油替代大豆油（均为基础饲料）。与 CON 相比，所有 n-3 处理组的鸡胸肉、大腿肉、肝脏、脂肪组织和血浆中的总 VLCn-3FA 含量更高，而在 AHI 和 FLAX 油的最高水平下观察到的增加最大（p<0.001）。以 7.5g/kg 的 AHI 油促进了肉鸡组织中 VLCn-3 的最有效合成和沉积，这是根据摄入的 n3FA 相对于组织中 VLCn-3FA 的沉积来衡量的。总之，ALA 和 SDA 油都增加了组织中 VLCn-3FA 的沉积，但随着饮食中油水平的增加，收益递减。
