Problems solved by technology

However, a large number of studies have shown that the bioavailability of inorganic zinc preparations is low, and a large amount of addition is required to meet the needs of animals. At the same time, a large amount of zinc will be discharged into the environment, causing pollution
Studies in recent years have found that the utilization rate of organic synthetic zinc preparations is significantly higher than that of inorganic zinc preparations, but some subsequent studies have also found that the utilization rate of organic synthetic zinc preparations is not stable, and its price is higher than that of inorganic zinc preparations. The utilization rate of organically synthesized zinc in actual production is not high

Abstract

The invention provides a preparation method of a fermentation state zinc feed additive. The preparation method comprises the following steps: firstly preparing a fermentation substrate by taking alcohol industry yellow water, bran, powder dregs, corn flour and other industrial and agricultural side products as raw materials, then performing microbiological screening and acclimatization and culture to obtain zinc-rich microorganism, inoculating to the prepared fermentation substrate and fermenting, and drying, grinding and packaging the fermented materials to obtain the fermentation state zinc feed additive. Compared with the chemically synthesized zinc feed additive, the fermentation state zinc feed additive adopts the powder dregs, bran, alcohol industry yellow water and other side products as culture raw materials and substrates, so that the resource utilization is increased, the production cost of the zinc feed additive is lowered, and the prepared fermentation state zinc feed additive is more stable in bioavailability and higher in absorption rate, and the zinc absorption rate is 30%-42% which is 2.3-3.3 times that of anhydrous zinc sulfate, and 2.1-3.0 times that of zinc-amino acid chelate.

Description

technical field [0001] The invention relates to the field of biological feed processing, in particular to a method for preparing a fermented zinc feed additive by using microorganisms. Background technique [0002] Zinc is one of the essential trace mineral elements in animals, which participates in the composition and activation of various enzymes in animals. Zinc deficiency can cause symptoms such as loss of appetite, decreased feed intake and production performance, skin and coat damage, dysplasia of male reproductive organs, decreased reproductive performance of female animals, and bone abnormalities. Due to the low utilization rate of zinc in most feed materials, adding additional zinc preparations to feed is an important measure to meet the zinc needs of animals. However, a large number of studies have shown that the bioavailability of inorganic zinc preparations is low, and a large amount of addition is required to meet the needs of animals. At the same time, a large...
