Embodiment 1

[0021] Commercially available castor meal, rapeseed meal and cotton meal are mixed into fermentation raw materials in a weight ratio of 1:1:1, put into a fermenter, add

[0022] Water and commercially available composite dry bacteria preparation, the composite dry bacteria preparation is made up of lactic acid bacteria, saccharomyces, bacillus, the weight ratio of fermentation raw material and water is 1: 0.2-0.25, and the weight ratio of fermentation raw material and composite dry bacteria preparation is 1 : 0.01, stirred evenly, fermented for 12 hours, inactivated, and dried into a composite fermentation raw material with a moisture content of not more than 10%; 25 kg of the composite fermentation raw material was weighed, and 40 kg of commercially available three insect powder and 15 kg of pumpkin seed powder were added , 1 kg of fish oil, 15 kg of flour, 1.5 kg of calcium dihydrogen phosphate, 2 kg of vitamin and mineral salt mixture and 0.5 kg of choline chloride, mix even...

Embodiment 2

[0024] It is basically the same as Example 1, except that the compound fermentation raw material is 30 kg, 35 kg of three insect powder, 10 kg of pumpkin seed powder, 0.5 kg of fish oil, and 10 kg of flour.

Embodiment 3

[0026] It is basically the same as Example 1, except that the composite fermentation raw material is 20 kilograms, 45 kilograms of three insect powder, 20 kilograms of pumpkin seed powder, 0.5 kilogram of fish oil, and 20 kilograms of flour.

Abstract

The invention discloses a mixed feed for sea-bass fish and a preparation method thereof. The mixed feed is made from the following raw materials in parts by weight: 35 to 45 of insect powders, 20 to 30 of a compound fermented material, 0.5 to 1 of fish oil, 10 to 20 of flour, 1.5 of calcium dihydrogen phosphate, 2 of a vitamin-mineral salt mixture, and 0.5 of choline chloride, wherein the compound fermented material is a fermented product of castor cake, rape cake and cotton cake with compound dry microbial inocula. The mixed feed is prepared by the steps as follows: mixing castor cake, rape cake and cotton cake according to a weight ratio of 1:1:1, and adding the compound dry microbial inocula composed of at least two of lactic acid bacteria, saccharomycetes, bacillus and geotrichum candidumlink strain for fermentation 2-24h, wherein the additive amount of the compound dry microbial inocula is 1% of the total weight of the fermentation raw material; and thoroughly mixing the raw materials, compounding, pelletizing and oven-drying to obtain the final product. The preparation method is simple and low in cost. The mixed feed for sea-bass fish is good in palatability and nutrition and can enhance disease resistance and stress resistance of sea-bass fish.

Description

technical field [0001] The invention relates to an artificial feed for fish, in particular to a compound feed for perch and a preparation method thereof. Background technique [0002] Perch is the main species of marine aquaculture in my country due to its fast growth, delicious taste and high economic benefits. At present, the main components of the artificial feed of perch are fish meal, bean dregs, flour, fish oil, calcium dihydrogen phosphate, multivitamins, multiminerals, choline chloride and other ingredients. The compound feed for sea bass, in addition to the conventional fish meal, bean curd and flour, etc., the compound feed for sea bass is also added with various bacteria and enzymes to make the utilization rate of the compound feed higher and the excretion of N and P less. The invention patent with the authorized announcement number CN1833543 discloses the compound feed of the perch. In addition to the conventional fish meal, soybean meal and flour, etc., the per...
