Abstract

The invention discloses a fermented feed capable of strengthening oxidation resistance and stress resistance of crayfish and a preparation method of the fermented feed.The method comprises the steps of adding oxidation resisting dark green feed components to the fermented feed, wherein the oxidation resisting dark green feed components contain fermentation mulberry leaf powder, one or more stem and leaf plants, and one or more berry plants; and mixing and stirring a phagostimulant, a compound additive, an adhesion agent and mixed fermentation bacterial liquid, performing constant-temperature short-time fermentation, and then performing granulation to obtain finished products of the feed. The raw materials of the feed are cheap and easy to obtain, the feed is simple to make, and the production cost is greatly reduced. The components can guarantee various nutrient indexes of the crayfish, the immunity and the liver function of the crayfish can be notably improved, fermented protein components are easy to separate out, digestive absorption by the crayfish is facilitated, health of intestines is facilitated, and quick growth of the crayfish can be promoted.

Description

technical field [0001] The invention relates to the field of aquatic compound feed, in particular to a method for preparing fermented feed that enhances the ability of crayfish to resist oxidative stress. Background technique [0002] Crayfish are omnivorous animals, eating both green grass and grains and animal feed. Beginning in May every year, crayfish are prone to a large number of deaths, commonly known as May plague. May plague is actually caused by a syndrome. After the temperature rises in May, the algae, substrate, flora, and various physical and chemical properties in the water body will undergo major changes. In the case of a decline, conditions are created for bacterial invasion and disease outbreaks. At the same time, in order to speed up the growth of crayfish, long-term feeding of high-protein feed will also burden the liver metabolism of crayfish, resulting in loss of appetite and poor vitality of crayfish. prone to disease. Oxygen free radicals (ROS) are...
