Method for preparing dairy cow feed additive

Abstract

The invention provides a method for preparing a dairy cow feed additive and belongs to the technical field of biology. The method comprises the steps of reacting at least one amino acid with rare earth to generate a rare earth amino acid complex; and mechanically mixing the rare earth amino acid complex with modified medical stone to obtain the rare earth amino acid-containing feed additive, wherein methyl p-hydroxycinnamate and dextro shikonin are contained in the rare earth aqueous solution for preparing the rare earth amino acid complex. The method for preparing the dairy cow feed additive,provided by the invention, has the advantages that the process is simple; the operating parameters are easy to control; the production energy consumption and the cost are low; the raw material loss is low; the purity of target products is high; the load capacity and the dispersing capacity are strong; and no side reaction occurs. The prepared additive is high in the stability and the absorptive utilization rate and low in the toxic and side effects and has the excellent properties of controlled release, moisture and water resistance, no oxidative deterioration and no agglomeration of particles.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a preparation method of a dairy cattle feed additive. Background technique [0002] In modern agricultural production, the scale of dairy farming is gradually formed, and the industrial system is basically established. In order to further promote and ensure the sustainable and healthy development of the milk industry and ensure the safety of the supply of fresh milk, professional farmers are constantly looking for scientific feeding methods from feed. Feed is roughly divided into eight categories according to the nutrients it contains: roughage, silage, green feed, protein feed, energy feed, vitamin feed, mineral feed, and feed additives. In the development of modern agriculture, dairy cattle feed needs to be supplemented with feed additives, so that dairy cows can maximize their potential for high-quality milk production, which is of great significance to the scientific...

Problems solved by technology

Compared with inorganic rare earths, organic rare earths have a more obvious effect on improving the production performance and economic benefits of dairy cows, but organic rare earths are easy to absorb moisture and agglomerate in the air, have poor fluidity and strong adsorption, and are easily adsorbed on feed when mixed with feed. Feed surface, not easy to mix evenly with feed

Before batching, the rare earth should be fully mixed with the quantitative medical stone to make the rare earth and medical stone adsorb each other, and then sent to the mixer to mix with the feed. Components clump together, affecting feed preparation and failing to achieve better results

[0007] The prior art such as the Chinese invention patent with the authorized announcement number CN100525640C discloses a rare earth feed additive and its preparation and use method. Forming a cation exchange resin containing active rare earths, although the ion exchange resin has a controlled and slow release effect on the loaded rare earths, thus greatly improving the absorption and utilization of rare earths, but it uses inorganic rare earths to react with ion exchange resins, and it is easy to enter animals Dissociate to form free metal ions, and free metal ions are highly toxic and likely to cause toxic side effects
