Self-assembled small peptide chelated manganese feed additive and preparation method thereof

Abstract

The invention relates to the technical field of small peptide chelated manganese, and particularly relates to a self-assembled small peptide chelated manganese feed additive and a preparation method thereof. The self-assembled small peptide chelated manganese feed additive comprises the following ingredients: amino acid, strong acid resin, inorganic manganese and methanol. Small peptide powder is prepared by utilizing the amino acid and the strong acid resin, and a small peptide solvent is obtained after the small peptide powder is dissolved; manganese carbonate is added into the small peptide solvent to form a chelate; and by adding the methanol into the chelate, the small peptide chelated manganese is obtained after the methanol is separated out. According to the invention, by adding the small peptide chelated manganese into a feed, both the preparation process and the preparation time are reduced, and the quality of piglets is improved. The invention solves the problems that in the existing feed additive preparation process, manganese sulfate monohydrate is mostly added as a feed additive, and although the manganese sulfate monohydrate is also one category of manganese, the average weight of the piglets after birth, the number of the piglets at the age of 14 days, the litter weight, the average weight and the lactation yield are all low.

Description

technical field [0001] The invention relates to the technical field of small peptide chelated manganese, in particular to a self-assembled small peptide chelated manganese feed additive and a preparation method thereof. Background technique [0002] Feed additives refer to small or trace substances added in the process of feed production, processing and use. They are used in a small amount in feed but have significant effects. Feed additives are the raw materials that must be used in the modern feed industry. They can strengthen the nutritional value of basic feed and improve animal production. performance, ensuring animal health, saving feed costs, and improving the quality of livestock products, etc., have obvious effects. Most of the livestock and poultry diets add manganese to the interior, and the most commonly used manganese is inorganic manganese. Generally speaking, manganese is in its The amount of retention in the body is very low, and livestock can obtain a suffic...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of self-assembled small peptide chelated manganese feed additive and preparation method thereof, to solve the problem that in the process of preparing the existing feed additive proposed in the above-mentioned background technology, most of them are to add manganese sulfate monohydrate as feed Although it is also a kind of manganese, the average birth weight of piglets, the number of piglets at 14 days, litter weight, average weight and lactation volume are all relatively low, and it is not easy for piglets to absorb manganese. Leading to the problem of reduced productivity of piglets
