Pollution-free organic big-head milter and flat fish feed and preparation method thereof

Abstract

The invention discloses a pollution-free organic big-head milter and flat fish feed, which is prepared by fermenting the following materials in part by weight: 100 to 300 parts of bran, 100 to 300 parts of peanut residue, 100 to 300 parts of corn flour, 50 to 200 parts of brown sugar, 100 to 300 parts of lees, 100 to 300 parts of wheat bran and 5 to 20 parts of yellow wine vinegar. The invention also discloses a preparation method for the pollution-free organic big-head milter and flat fish feed, which comprises the following steps of: (1) crushing the materials: crushing the bran and the wheat bran into powder to obtain bran powder and wheat bran powder for later use; (2) mixing: weighing the bran powder, the peanut residue, the corn flour, the brown sugar, the lees, the wheat bran powder and the yellow wine vinegar in a ratio, and then mixing the materials uniformly to obtain a mixed material; and (3) fermenting and decomposing: putting the mixed material obtained in the step (2) into a fermentation container to perform closed fermentation, heating the material to the temperature of between 45 and 70 DEG C during fermentation, and obtaining the organic big-head milter and flat fish feed in 5 to 7 days of fermentation. The materials do not contain harmful components to the human body, do not cause medicinal residues in the raised fish, and are suitable for the taste of the big-head milter and the flat fish.

Description

technical field [0001] The invention relates to a pollution-free organic fish feed and a preparation method thereof, in particular to a pollution-free organic bighead male fish and flat fish feed and a preparation method thereof. Background technique [0002] The fish feeds currently on the market are all conventional fish feeds, which are mainly made of fish meal, starch, minerals, etc. mixed. Some add various vitamins and trace elements to fish feed to provide fish with more vitamins or trace elements. The materials of the existing fish feed have not been processed by microorganisms such as fermentation, and the digestion and utilization rate of the fish after eating is not high, and it is easy to get sick and has a bad body shape. Although existing research institutes have researched and developed pollution-free organic fish feeds for big-headed male fish and flat fish, etc., and the formula of fish feed is rich in nutrients, but due to no consideration of adapting to th...

AI Technical Summary

Problems solved by technology

The existing fish feed materials have not been treated with microorganisms such as fermentation, and the digestion and utilization rate of fish after eating is not high, and they are prone to disease and poor body shape

Although existing research institutes have researched and developed pollution-free organic fish feeds for big-headed male fish and flat fish, etc., and the formula of fish feed is rich in nutrients, but due to no consideration of adapting to the taste of big-headed male fish and flat fish, these two kinds of fish are harmful to all fish. The new feed developed was not cold, the amount of feed intake was very small, and the weight gain was slow. Therefore, the new feed developed was not successful

[0003] In addition, some existing fish feeds also contain substances harmful to human health, such as adding estrogen to accelerate fish growth and gain weight quickly, or adding antibiotics to enhance fish resistance to disease. Drug residues exceed the standard, causing major food safety and hygiene problems
