Embodiment 1

[0043] Embodiment 1 provides a kind of method using feather protein hydrolyzate to make composite organic trace elements under laboratory conditions, comprising the following steps:

[0044]S1. Prepare a feather protein hydrolyzate, and the measured dry matter content is 38.3%, and the amino acid content in the dry matter is 39.6%. Take 0.5kg of feather protein hydrolyzate into a beaker, place the beaker in a water bath, and set the temperature of the water bath to 70°C. The pH of the hydrolyzed solution was measured with a pH meter, and the aqueous sodium hydroxide solution was added in several portions while stirring until the pH was 7.0±0.2, and the addition of the aqueous sodium hydroxide solution was stopped.

[0045] S2. Weigh 90g of feed-grade ferrous sulfate monohydrate, slowly add it to the beaker, and continuously stir the hydrolyzate in the beaker during the addition; then raise the temperature of the water bath to 80°C, heat for 30 minutes, and continue to stir dur...

Abstract

The invention relates to a method for preparing composite organic microelements from feather protein hydrolysate, and relates to the technical field of microelement preparation, the preparation method comprises the following steps: S1, heating the feather protein hydrolysate to 60-90 DEG C, then adjusting the pH value to 6.0-7.5, then adding metal sulfate, and uniformly stirring and mixing; s2, continuously heating and continuously stirring until the reaction liquid is completely reacted; s3, after the reaction is finished, adding an auxiliary material carrier, and uniformly stirring and mixing to obtain a pasty material; and S4, heating and baking the pasty material to obtain a dry material. The feather protein hydrolysate is used as a raw material, is low in cost, is in a liquid state, can directly react, is reduced in cost and is low-carbon and environment-friendly; the utilization rate in animal digestive tracts is higher, various amino acids are used as ligands, and absorption channels are different; amino acid is easier to balance, and compared with inorganic microelements, the compound organic microelements are low in addition amount and have little damage to sensitive nutrients in the feed.

Description

technical field [0001] The present application relates to the field of organic trace element preparation technology, in particular to a method for preparing composite organic trace elements from a feather protein hydrolyzate. Background technique [0002] In the feed industry, trace elements mainly refer to copper, iron, zinc, manganese, iodine, selenium, cobalt and other elements. Although the addition amount of trace elements in the feed is small, it plays a very important role and is an indispensable component in the feed. Most of the trace elements in traditional feed are added in the form of sulfate compounds, such as copper sulfate, ferrous sulfate, zinc sulfate, etc. In recent years, with the development of the feed industry, compound organic trace elements mainly based on amino acid chelate trace elements have gradually been widely used, such as organic compounds such as zinc methionine and iron glycinate. [0003] Amino acid chelated trace elements are synthesized...
