Abstract

The invention relates to the field of feed additives, and provides a feed additive for resisting nutrition stress of tilapia and application of the feed additive. Main active ingredients of the feed additive include nicotinic acid and reduced glutathione, and lotus leaf powder is used as a carrier. Under the background that the increasing nutrition level of current tilapia feed, especially the increasing level of digestible fat and carbohydrates, results in increased nutrition stress of the tilapia and weakened disease resistance, the feed additive simple in composition is provided to obviously improve the anti-oxidation capability and health level of the tilapia, reduce occurrence of diseases, and increase fishermen's income.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a feed additive for resisting nutritional stress of tilapia and its application. Background technique [0002] Nutritional stress refers to the stress induced by excessive metabolic levels if the concentration of one or more nutrients is too high or too low. This is mainly because nutrients need to be metabolized in the cells. When the metabolism increases, the oxygen consumption of the tissue cells in the body will increase, and the high oxygen consumption will cause the cells to produce too much reactive oxygen free radicals. species, ROS) molecules, such as hydrogen peroxide (H 2 o 2 ), superoxide anion and hydroxyl radicals, etc. Excessive free radicals destroy the balance between the body's oxidation and antioxidant systems, thereby putting the body in a state of oxidative stress, reducing the growth performance of the body, and causing damage at the systemic and local levels...
