Abstract

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.

含硬脂脂酸的石楠花油与高α -亚麻酸亚麻籽油在两个水平上对肉仔鸡组织中omega-3富集的比较

极长链ω -3脂肪酸(VLCn-3 FA)对肉鸡肉的富集具有重要意义，因为它们对人体健康有益。研究了天然含有硬脂酸(SDA)和高α -亚麻酸(ALA)的亚麻籽(FLAX)油对肉鸡组织中VLCn-3 FA含量的影响。55只Cobb 500雏鸡在第12 ~ 35天饲喂含有27.9 g/kg大豆油或AHI或亚麻油的对照(CON)饲粮，分别以7.5或22.5 g/kg的水平替代大豆油(均在饲喂基础上)。与对照组相比，所有n-3处理组的乳腺、大腿、肝脏、脂肪组织和血浆中的VLCn-3 FA总含量都更高，其中AHI和亚麻油含量最高时增幅最大(p < 0.001)。7.5 g/kg的AHI油促进肉仔鸡组织中VLCn-3的合成和沉积效率最高(以VLCn-3 FA在组织中的沉积量相对于n3 FA摄入量)。综上所述，ALA和SDA油均增加了VLCn-3 FA在组织中的沉积，但随着饲粮中ALA和SDA油含量的增加，这种效果逐渐减弱。
