Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for preparing an environmentally friendly compound feed for freshwater fish, which has the advantages of improving feed utilization, reducing environmental pollution, and reducing the probability of disease occurrence in the breeding process of freshwater fish, and solves the existing problems. Incomplete feed digestion leads to increased excrement, which pollutes water quality and increases the incidence of freshwater fish

preparation example Construction

[0020] A method for preparing an environment-friendly compound feed for freshwater fish. The raw materials and weight ratio of the environment-friendly compound feed for freshwater fish are 16-20 parts of fish meal, 6-10 parts of corn gluten meal, 22-25 parts of soybean meal, and 11-25 parts of expanded soybean meal. 15 parts, 12-20 parts of peanut bran, 6-10 parts of rapeseed meal, 1-5 parts of fish oil, 1-5 parts of soybean oil, 0.2-1 part of calcium dihydrogen phosphate, 0.2-1 part of choline chloride, compound probiotics 0.1-1 part of bacteria, 0.2-0.6 part of vitamin C, 0.1-0.3 part of compound multidimensional;

[0021] Among them, the freshwater fish environmental protection compound feed is prepared by the following process steps:

[0022] Step (1): first accurately weigh the weight of each raw material according to the breeding ratio;

[0023] Step (2): first pulverize the raw materials with larger particles, and then stir them evenly with a mixer;

[0024] Step (3)...

Embodiment 1

[0029] First, accurately weigh the weight of each raw material according to the breeding ratio; then crush the raw materials with larger particles for the first time, and then stir them evenly through a mixer; The material is put into the conditioner, and heated hot steam is introduced to keep the temperature of the material and the space at 100±5°C; the material that has been reconditioned and tempered successively passes through the extrusion assembly and the discharge assembly in the extruder, and the compound probiotics pass through. Spraying technology is added; finally, the finished feed pellets are dried and cooled, sieved to remove powder, and then stored or packaged.

Embodiment 2

[0030] Embodiment two: need to cross 80 mesh sieves after adding raw material in step (3) in embodiment one and carrying out superfine pulverization;

[0031] Firstly, the weight of each raw material is accurately weighed according to the breeding ratio; then the raw material with larger particles is crushed for the first time, and then stirred evenly by a mixer; Mesh sieve, add oil, continue to mix; then put the material into the conditioner, pass hot water steam, keep the temperature of the material and the space at 100±5°C; Forming and discharging assembly, compound probiotics are added after spraying technology; finally, the feed pellets are dried and cooled, sieved to remove powder, and then stored or packaged. Embodiment three: the time of adding material conditioning and tempering in step (4) in embodiment two is 2-5 minute;

Abstract

The invention relates to the technical field of aquaculture. The invention particularly relates to a preparation method of a freshwater fish environment-friendly compound feed. The freshwater fish environment-friendly compound feed is prepared from the following raw materials in parts by weight: 16 to 20 parts of fish meal; 6 to 10 parts of corn protein powder; 22-25 parts of soybean meal, 11-15 parts of puffed soybean meal, 12-20 parts of peanut bran, 6-10 parts of rapeseed meal, 1-5 parts of fish oil, 1-5 parts of soybean oil, 0.2-1 part of monocalcium phosphate, 0.2-1 part of choline chloride, 0.1-1 part of composite probiotics, 0.2-0.6 part of vitamin C and 0.1-0.3 part of composite multivitamin. The method comprises the following steps: firstly, the weight of each raw material is accurately weighed according to the hybridization ratio; the raw materials with larger particles are subjected to primary crushing; and the raw materials are uniformly mixed thorugh a mixer. The feed canbe digested more easily, the situation that the freshwater fish cannot digest the feed and redundant feed is discharged as waste is avoided, the amount of the freshwater fish excreted waste is reduced, pollution of excrement to the water environment is avoided, the quality of the water environment is improved, and the morbidity probability of the freshwater fish is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for preparing an environment-friendly compound feed for freshwater fish. Background technique [0002] In recent years, my country's freshwater aquaculture has developed rapidly, and the proportion of freshwater aquaculture in the national economy has been increasing year after year. Freshwater fish farming mainly refers to fish farming using inland water such as ponds, reservoirs, and lakes. Freshwater fish farming is the main component of inland aquaculture. In recent years, with the continuous development of aquaculture technology, freshwater fish production methods are also diverse, such as pond fish farming, lake fish farming, reservoir fish farming, cages Breeding, etc., in order to maximize the profit, the farmers make the fish grow rapidly, and blindly raise the high feeding rate for a long time, resulting in the incomplete digestion of the feed by the fish,...
