进行了三项饲养研究，以研究饲粮大豆卵磷脂（SBL）是否提高黄尾鱼对非鱼粉（SPC为基础的饲料）的采食量，并阐明哪种磷脂（PL）组分可有效提高采食量。在实验1和2中，鱼被喂食0%-5%的SBL水平，并且显示，鱼的日摄食率（DFR）对于SBL 2%显著高于SBL 0%，而在饮食中SBL的进一步增加没有额外地增加DFR。此外，饲料中没有喂食兴奋剂（FS）的鱼的DFR是最低的饮食治疗，表明SBL没有提高黄尾鱼的摄食量的效果。在实验3中，给鱼喂食含有2% PL的几种产品的饮食。这些产品中的磷脂酰胆碱和磷脂酰肌醇浓度与鱼的DFR呈正相关。这一结果表明，当饲料中存在FS时，SBL中的这两个组分对提高黄尾鱼的采食量是有效的。
Three feeding studies were conducted to investigate whether dietary soybean lecithin (SBL) enhanced feed intake of non‐fish meal, SPC‐based diet, in yellowtail, and also to clarify which fraction of phospholipid (PL) was effective to enhance feed intake. In experiments 1 and 2, fish were fed SBL level at 0%–5%, and it was revealed that the daily feeding rate (DFR) of fish was significantly higher for SBL 2% than for SBL 0%, while a further increase of SBL in the diet did not additionally increase the DFR. Moreover, the DFR of fish fed a diet without feeding stimulants (FS) was the lowest among the dietary treatments, indicating that the SBL does not have an effect of enhancing feed intake in yellowtail. In experiment 3, fish were fed a diet with several products containing PL at 2%. Phosphatidylcholine and phosphatidylinositol concentrations in these products positively correlated to the DFR of fish. This result revealed that these two fractions in the SBL are effective for enhancing feed intake of yellowtail when FS is present in the diet.
