Problems solved by technology

However, with the deepening of research, it was found that the utilization rate of artificially synthesized organic iron was not stable, and some studies even found that the utilization rate of organic iron preparations was not as high as that of ferrous sulfate.

Abstract

The invention discloses a preparation method of a fermentation-state iron feed additive. The method comprises the following steps: firstly, by adopting industrial and agricultural by-products such as alcohol industry yellow water, bran and powder dregs as raw materials, preparing a fermentation medium; carrying out microbiological screening and domesticated incubation to obtain iron-rich microorganisms, and inoculating the microorganisms into the obtained fermentation medium and fermenting; and drying, crushing and packaging the fermented material to prepare the product. Compared with chemical synthesized iron feed additives, the fermentation-state iron feed additive has the advantages that the by-products such as powder dregs, bran and alcohol industry yellow water are adopted as culture raw materials and mediums, so that resource utilization is expanded; the production cost of the iron feed additive is reduced; the prepared fermentation state iron feed additive is relatively stable in bio-availability, and relatively high in absorptivity; and the iron absorptivity is greater than 24.7%, is 5.7 times that of ferrous sulfate monohydrate, and is 1.8 times that of iron 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 iron feed additive by using microorganisms. Background technique [0002] Iron is one of the essential trace mineral elements for animals, iron deficiency is more common in young livestock and poultry, breeding livestock and so on. Iron deficiency can lead to decreased animal production performance, reduced resistance, and anemia in severe cases. Therefore, adding additional iron preparations to the feed is an important measure to meet the iron requirements of animals. However, studies have found that inorganic iron preparations (such as ferrous sulfate, ferrous chloride, etc.) have low bioavailability, and their absorption and utilization rate is less than 10%, and the rest of iron is discharged into the environment through feces, causing pollution. Studies in recent years have found that the utilization rate of organic iron preparat...
