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.
