由于鱼粉和鱼油资源有限，水产养殖业的成本高，有必要寻找替代的可持续的蛋白质和脂质来源。为此，本试验配制了7种不同饲料，分别添加不同水平的动物副产物、植物蛋白、鱼油和菜籽油，饲喂大西洋鲑鱼，并研究了它们对大西洋鲑鱼生长性能、肌肉脂类和脂肪酸组成的影响。蛋白质来源包括凤尾鱼、家禽、羽毛、血液、玉米、大豆和小麦。生长性能表明，鱼粉和鱼油含量最低的饲粮增重和最终体重最低，其次是动物副产品含量最高的饲粮。脂类分析显示，不同饮食对肌肉总脂含量的影响无统计学差异。然而，主要脂类之间存在显著的统计学差异；三酰基甘油、磷脂和固醇。含有1.4%的omega-3长链脂肪酸的饮食导致三酰甘油和磷脂的含量最高。分别含有中等和低水平鱼油和鱼粉的饲料，导致肌肉中ω3脂肪酸的水平与饲喂高水平鱼粉和鱼油的饲料时一样高。本研究结果提示，饲粮中添加低水平鱼粉和中等水平鱼油对肌肉中ω3脂肪酸组成没有显著影响。只要饲料中至少含有5%的鱼油，且动物副产品不超过饲料的26%，鱼粉可降至5%而不影响生长。
Due to limited fish meal and fish oil resources and their high costs for the aquaculture industry, it is necessary to find alternative sustainable sources of protein and lipids. Therefore, seven different diets were formulated with different levels of animal by-products, vegetable proteins, fish oil and rapeseed oil, to feed farmed Atlantic salmon, and their effects on growth performance, muscle lipid class, and fatty acid composition were examined. Protein sources included anchovy, poultry, feather, blood, corn, soy and wheat. Growth performance indicated that the diet with the lowest fish meal and fish oil content resulted in the lowest weight gain and final weight, followed by the diet containing the highest level of animal by-products. The lipid class analysis showed no statistical difference in the muscle total lipid content using different diets. However, significant statistical differences were observed among the main lipid classes; triacylglycerols, phospholipids, and sterols. The diet containing 1.4% omega-3 long-chain fatty acids resulted in the highest content of triacylglycerols and phospholipids. Diets containing medium and low levels of fish oil and fish meal, respectively, led to as high a level of ω3 fatty acids in muscle as when fish were fed diets with high levels of fish meal and fish oil. The results of this study suggest that feeding a diet containing low levels of fish meal and moderate levels of fish oil does not significantly affect ω3 fatty acid composition in muscle. Fish meal could be reduced to 5% without affecting growth as long as there was a minimum of 5% fish oil, and animal by-products did not exceed 26% of the diet.
