Fish forage formula and preparation method thereof

Abstract

The invention discloses a fish forage formula which comprises, based on weight parts, the following components: 50-60 parts of corn flour; 10-15 parts of sweet potato powder; 5-10 parts of bean cake powder; 3-5 parts of bone powder; 10-15 parts of egg powder; 1-3 parts of active enzyme; 1-2 parts of salt; and 20-30 parts of diluents. The preparation method of the fish forage formula comprises the steps of (1) preparing a premix; (2) crushing; and (3) preparing fish forage. The forage formula provided by the invention has comprehensive and balanced nutrient composition, and the whole process of preparation has no pollutant and is clean and environment-protective, the immunization capability of fish is enhanced, and the generation rate of insect disease is reduced.

Description

technical field

[0001] The invention relates to a fish feed formula and a preparation method thereof, belonging to the technical field of fish farming. Background technique

[0002] At present, fish farming is developing rapidly in our country, and fish products also play a pivotal role in people's daily life; with the development of fish farming, chemical agents are usually used for treatment of fish farming diseases. This is not a good solution for both the cultured water body and the fish itself, and will cause the quality and safety of fish and the deterioration of the breeding environment. The above-mentioned fish diseases are mainly caused by the unbalanced nutrition of the traditional feed, so that the immunity of the fish is reduced, and finally the fish diseases are caused. Contents of the invention

[0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a fish feed with balanced nutrition, which can effe...
