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.

含有硬脂酸的 Ahiflower 油与高 α-亚麻酸亚麻籽油在两个水平上对肉鸡组织 omega-3 富集的比较

用超长链 omega-3 脂肪酸 (VLCn-3 FA) 富含肉鸡是很有趣的，因为它们对人类健康有益。Ahiflower® (AHI) 油 ( Buglossoides arvensis ) 的能力)，其天然含有硬脂酸 (SDA) 和高α-亚麻酸 (ALA) 亚麻籽 (FLAX) 油，以丰富肉鸡组织中的 VLCn-3 FA 含量。55 只 Cobb 500 雏鸡在出生后 12 至 35 天被饲喂含有 27.9 g/kg 大豆油或 AHI 或 FLAX 油的对照 (CON) 日粮，每只日粮的替代量分别为 7.5 或 22.5 g/kg豆油（全部以喂食为基础）。与 CON 相比，所有 n-3 处理的乳房、大腿、肝脏、脂肪组织和血浆中的总 VLCn-3 FA 含量均高于 CON，在最高水平的 AHI 和 FLAX 油中观察到的增加最大（p < 0.001)。7.5 g/kg 的 AHI 油促进 VLCn-3 在肉鸡组织中最有效的合成和沉积，测量为组织中 VLCn-3 FA 相对于 n3 FA 摄入量的沉积。总之，ALA 和 SDA 油都增加了 VLCn-3 FA 在组织中的沉积，但是当增加油的饮食水平时，收益递减。
