Saturated Fatty Acid-Rich Soybean Oil Spares Fish Oil In Seabass Feed

摘要

Fish oil sparing has proven difficult for fish species that require the long-chain polyunsaturated fatty acids (LC-PUFAs) abundant in fish oil but lacking in most alternative fats and oils used in aquafeeds. Trials with seabass, a carnivorous species,suggested its LC-PUFA requirements could be reduced by feeding saturated fatty acid-rich lipids like hydrogenated soybean oil, allowing a greater level of fish oil sparing without growth impairment or tissue profile modification than is possible with C_(18) PUFA-rich lipids.
