Abstract

The invention relates to a feed additive for fishes and a preparation method thereof. The feed additive for fishes consists of the following components: acanthopanax, polysaccharides from poria cocos mycelia, hippophae rhamnoides sinensis, sodium acetate, acetic acid, bamboo vinegar, potassium sorbate, bile acid, lysine sodium and wheat middling. The invention also provides a method for preparing the fish feed. The fish feed additive disclosed by the invention has the advantages that the immunity of the fishes is enhanced, the survival rate is increased, the incidence rate is reduced, the attractant effect is improved, the healthy growth of the fishes is promoted and the like. Particularly, the feed additive disclosed by the invention can be matched with any fish feed, the fish feed can be prevented from mildewing and deteriorating for a long time, the components interact with one another, and digestive absorption of the fish is promoted, so that the fish meat is tasty and delicious.

Description

Technical field [0001] The invention relates to a feed additive, in particular to a feed additive for fish and a preparation method thereof. Background technique [0002] Fish feed additives, also known as fish feed supplements, supplements, enhancers, growth promoters, etc. Refers to the various amino acids, minerals, vitamins, antibiotics, hormones, enzyme preparations, insect repellents, antioxidants, antifungal agents, coloring agents and food cooked enhancers added to the compound feed. Its addition in compound feed is only a few thousandths or ten thousandths, but it has a great effect. Mainly as an important nutrient balance substance of compound feed, it can improve the nutrient composition of compound feed, improve the utilization rate of fishery feed, promote the appetite and normal development of aquatic animals, prevent various diseases, reduce the loss of nutrients during storage, and relieve toxicity. Improve the quality of aquatic products, among which: [0003] A...
