Three isocaloric diets were prepared. Diet 1 (Control) contained 22% herring oil. In diets 2 and 3, a third and a half of the herring oil was replaced, respectively, by an animal fat (lard) which contained a high percentage of saturated fatty acids. Each diet was fed to duplicate groups of rainbow trout for 14 wk. The results of the feeding trial indicated that the concentration of the saturated fatty acids in trout body lipid did not increase despite the high concentration of these fatty acids in Diets 2 and 3. Fish growth, feed efficiency, mortality and the level of fatty acids deposited in fish body lipid and phospholipids are discussed.
制备了三种等热量饮食。饮食1（对照）含有22%的鲱鱼油。在饮食2和3中，分别用含有高比例饱和脂肪酸的动物脂肪（猪油）替代了三分之一和一半的鲱鱼油。每种饮食分别投喂给两组重复的虹鳟鱼，持续14周。饲养试验结果表明，尽管饮食2和3中饱和脂肪酸浓度很高，但虹鳟鱼体脂中饱和脂肪酸的浓度并未增加。文中讨论了鱼类生长、饲料效率、死亡率以及鱼体脂和磷脂中沉积的脂肪酸水平。
