鱼类精氨酸需求研究进展

精氨酸是迄今研究的所有鱼类的必需氨基酸。近年来,在确定鱼类精氨酸需要量方面取得了巨大的进展。然而,仍然有许多养殖鱼类对精氨酸的需求有待研究。在已有的报道中,鱼类精氨酸需求存在种内和种间差异,而且这种差异较大。这篇论文综述了鱼类精氨酸需求的研究进展,包括五方面的内容,即鱼类对精氨酸的需要量,饲料中精氨酸含量对鱼类的影响,影响鱼类精氨酸需要量的因素,评价鱼类精氨酸需要量所采用的指标以及精氨酸和赖氨酸之间的相互关系。

Advance in researches on arginine requirement for fish:a review

Arginine is an indispensable amino acid required by all fish species investigated to date. In recent years more research has been conducted to assess and confirm arginine requirement determined by growth performance. However, there are still many cultured fish whose arginine requirement needs to be qualified. Moreover, evidence has shown that large variation exists in the values estimated of arginine requirement among fish species. The paper reviews arginine requirement of fish based on available information in the literature. Factors influencing the estimates are described in details, and indices of assessing arginine requirement, as well as the interaction between arginine and lysine is also discussed.
