preparation example Construction

[0029] A method for preparing protein feed, comprising the steps of:

[0030] (1) Take monosodium glutamate wastewater for distillation, repeat the distillation 4~5 times, combine the distillate, take the distillate and add it to distilled water and copper sulfate solution with a concentration of 0.001mol / L at a mass ratio of 1:10:1, and adjust the pH to 10 ~10.5, keep at 50~55°C for 30~40min, centrifuge, take the precipitate, then place it in a water bath at 95~100°C for 2~3h, concentrate under reduced pressure, and dry to obtain dry product A, which is set aside;

[0031] (2) According to the number of parts by mass, take 5-8 parts of Epimedium, 4-7 parts of Tartary Buckwheat, 2-3 parts of Astragalus, 4-6 parts of Licorice, 12-15 parts of mulberry leaves, 6-8 parts of Eucommia, Mix 2~4 parts of mugwort leaves, crush them through a 100-mesh sieve, collect the mixed and sieved particles, add petroleum ether at a mass ratio of 1:7, and extract for 3~5 hours to obtain the extract ...

Embodiment 1

Abstract

The invention belongs to the technical field of feed preparation, and particularly relates to a preparation method of protein feeds. The preparation method disclosed by the invention comprises the following steps of extracting a compound amino acid concentrate from monosodium glutamate wastewater and then performing chelation on trace elements, wherein the monosodium glutamate wastewater containsa great quantity of organic substances, inorganic salts, various amino acids, bacterial proteins and nucleotide degradation products, so that the monosodium glutamate wastewater can promote the growthand the development of animals and improve the immunity of the animals; the monosodium glutamate wastewater is high in interference resistance, easy to digest and absorb by animals and plants and high in biological potency, and can supplement trace elements while supplementing amino acids; copper is an essential trace element for livestock and poultry, and has a positive effect on the growth of the livestock and poultry; through various copper-containing enzymes, such as peroxidase, ceruloplasmin and dismutase, the oxidation-reduction process in organisms is influenced; and copper deficiencycan directly lead to nutritional deficiency and influence normal metabolism, so that the survival rate of the animals and plants and the utilization and conversion rate of the protein feeds can be increased after the copper is added to the protein feeds.

Description

technical field [0001] The invention belongs to the technical field of feed preparation. Specifically relates to a preparation method of protein feed. Background technique [0002] With the rapid development of aquaculture and feed industry, my country has become one of the largest aquaculture production countries in the world. At present, the serious shortage of protein feed in my country and the abuse of antibiotics have become a major bottleneck in the development of feed and aquaculture industry. Therefore, it is a common urgent need in the development of my country's feed and aquaculture industry to find high-quality and efficient plant protein raw materials, reduce the cost of aquaculture feed, and reduce the occurrence of aquaculture animal diseases. solved problem. [0003] The crude protein content in leftovers such as livestock and poultry blood meal and meat meal is as high as 80%, and has been used to replace some fish meal and soybean meal for a long time to pr...
