Acidifier for piglet feed, and preparation method thereof

Abstract

The present invention relates to an acidifier for a piglet feed, and a preparation method thereof. The acidifier comprises the following components, by weight, 25-45% of phosphoric acid, 8-15% of lactic acid, 5-10% of fumaric acid, 5-10% of citric acid, 3-8% of calcium formate, 10-20% of white carbon black, 10-20% of calcium hydrogen phosphate, and 10-20% of stearic acid. According to the preparation method, the components are subjected to mixing, heating, granulation, screening and other process steps to prepare the acidifier for the piglet feed. Compared with the acidifier in the prior art, the acidifier of the present invention has advantages of good use effect, stable product performance, simple synthesis route, ensured acid-sensitive nutrient substance titer, and the like.

Description

technical field [0001] The invention relates to a feed additive and a manufacturing method thereof, in particular to an acidifier for piglet feed and a manufacturing method thereof. Background technique [0002] In the prior art, the acidifiers used in the production of piglet feed are simple adsorption and mixed types, and the active ingredients of the products produced cannot be effectively protected, and the following problems may occur during the use of the products: [0003] (1) Low melting point and volatile active ingredients (such as formic acid, propionic acid, etc.) are easily lost during processing, storage and use, and the stability of product quality cannot be effectively guaranteed; [0004] (2) The unprotected active ingredient (acid) will react with other alkaline nutrients in the feed, thereby reducing the potency of nutrition in the feed, and the stability of the quality of the feed product cannot be effectively guaranteed; [0005] (3) Some active ingredi...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the acidifiers used in the production of piglet feed are simple adsorption and mixed types, and the active ingredients of the products produced cannot be effectively protected, and the following problems may occur during the use of the products:

[0003] (1) Low melting point and volatile active ingredients (such as formic acid, propionic acid, etc.) are easily lost during processing, storage and use, and the stability of product quality cannot be effectively guaranteed;

[0004] (2) The unprotected active ingredient (acid) will react with other alkaline nutrients in the feed, thereby reducing the potency of nutrition in the feed, and the stability of the quality of the feed product cannot be effectively guaranteed;

[0005] (3) Some active ingredients (such as: phosphoric acid) are medium-strong acids with strong corrosiveness. Phosphoric acid without effective protection will damage the oral mucosa of animals and affect the palatability of feed to a certain extent, thereby affecting the feed intake of pigs ;

[0006] (4) The acidifier that has not been effectively treated will be released immediately when it enters the pig body, thereby affecting the secretion of gastric acid and pepsin of the pig itself;

[0007] (5) Due to the above problems, the acidifier products produced by this process show low effect, ineffective or negative effect in the actual use process

[0014] For formula 3: first, calcium lactate and calcium formate are organic acid salts, which cannot provide H+, and the purpose of acidifier is to use the H+ provided by acid, so the selection of raw materials is invalid; second, calcium lactate or calcium formate is in Under certain circumstances, it will react with fumaric acid or citric acid to generate heat, which will cause the product to agglomerate during storage; third, the amount of acid used in the formula is low, and the amount required in the feed is high. Very low price / performance ratio (low product use value)
