This research was conducted to gather some basic information necessary for the development of non-fish meal dry diets for yellowtail. For the improvement of dietary value of non-fish meal diets supplementation of essential amino acids (EAA) is necessary, taking into consideration that their absorption into plasma must be synchronized with those derived from dietary protein for their effective utilization. Therefore, postprandial changes of FAA in plasma and feed digesta were examined in yellowtail by feeding them three types of diets {(soft-dry pellet (SDP), extruded pellet (EP), and single moist pellet (SMP)}, all having almost the same formulation with or without supplemental EAA.The supplemental EAA were found to be efficiently absorbed by yellowtail improving feed performances differing between diets, being highest for the SDP and lowest for the SMP group. However, the growth performance of fish fed the non-fish meal diets with EAA were inferior to those of fish on the control fish meal diet, in spite of the fact that the former were fortified with EAA to simulate the levels of the control diet. Although supplemental EAA were efficiently absorbed, the plasma methionine levels were markedly higher than those of fish fed the control diet. This may have caused an amino acid imbalance may have lowering the feed performances. For effective utilization, absorption of supplemental crystalline EAA into plasma must be synchronized with those derived from dietary protein, and this was found to be closely related to evacuation timing of the diet from the stomach. Thus the utilization efficiency differed between types of diets based on their physical properties such as hardness.

进行了这项研究是为了收集一些用于开发非粉状干饮食的基本信息。为了改善非鱼饮食补充必需氨基酸（EAA）的饮食价值，必须考虑到它们的吸收必须与饮食蛋白衍生的那些具有有效利用的饮食蛋白同步。因此，通过喂食三种类型的饮食来检查血浆和饲料消化中FAA的餐后变化{（柔软干燥的颗粒（SDP），挤出的颗粒（EP）（EP）（EP）和单个潮湿的颗粒（SMP）}，并通过供应不得及格的供应效率。饮食是SDP最低的，对于SMP组，喂养的鱼的生长性能与对照鱼粉饮食相比，饮食量低于鱼类的饮食，尽管前者是通过EAA加强了饮食的含量。酸性失衡可能会降低饲料性能以进行有效利用，将补充晶体EAA吸收到血浆中必须与饮食蛋白质的含量同步，并且发现这与饮食中饮食的疏散时间密切相关。因此，饮食类型的利用效率根据其物理特性（例如硬度）而有所不同。
