Enteric coated fodder acidifying agent and preparation method thereof

Abstract

The invention discloses an enteric coated fodder acidifying agent which comprises the following ingredients by weight: 8 to 20 parts of a citric acid, 8 to 20 parts of a fumaric acid, 7 to 15 parts of a benzoic acid, 5 to 20 parts of a malic acid, 3 to 15 parts of a formic acid, 2 to 10 parts of an acetic acid, 6 to 15 parts of a propanoic acid, 2 to 5 parts of a butyric acid, 10 to 20 parts of an emulsifier, and 15 to 50 parts of an enteric slow-release coating material. Meanwhile, the invention discloses a preparation method of the enteric coated fodder acidifying agent. The preparation method comprises the following steps: preparation of an acidifying agent suspending liquid, preparation of an acidifying agent emulsion liquid, fluidization of the acidifying agent emulsion liquid, atomization of the enteric slow-release coating material, preparation of the enteric coated fodder acidifying agent, and the like. The enteric coated fodder acidifying agent prepared according to the preparation method has the advantages that the product purity is high; the enteric coated fodder acidifying agent is released slowly only after arriving the rear segment of an animal intestinal canal, so as to effectively play the bacteriostatic role and improve animal alimentary canal micro-ecology.

Description

technical field [0001] The invention belongs to the technical field of animal feed additives, in particular to an enteric-coated feed acidifier and a preparation method thereof. Background technique [0002] Adding an appropriate amount of acidulant to livestock and poultry feed can activate a variety of digestive zymogen activities, promote the digestion and absorption of nutrients and prevent diarrhea; reduce the impact caused by heat stress; reduce the risk of transmission of pathogenic bacteria such as E. coli and Salmonella. Among them, small molecular organic acids such as formic acid, acetic acid, and propionic acid can not only reduce the pH value, but also have an inhibitory effect on Gram-negative bacteria; large molecular organic acids such as fumaric acid and lactic acid can reduce the pH value of the gastrointestinal tract, achieving an indirect effect. Reduces the action of harmful germs, but they only work in the stomach and do not lower the pH in the small in...

Problems solved by technology

The patent application with the application number 200910231504.3 discloses an "acidulant for suckling piglet feed and its preparation method", which is made from the following raw materials in the following weight ratio: 40-55 parts of L-lactic acid, 20 parts of fumaric acid -25 parts, 2-4 parts of citric acid, 2-3% of excipients, 7-8% of sodium hydroxymethyl cellulose, and the rest is white carbon black (that is, silicon dioxide). The disadvantage is that part of the acid is exposed outside, It is easy to react with other raw materials in the feed, and is easy to be released in the mouth after being eaten by animals, which affects palatability. The acidifier mainly acts on the front part of the digestive tract and cannot reach the intestinal tract

2. The carrier (commonly diatomaceous earth, silica gel and silicon dioxide, etc.) absorbs liquid acid and mixes it with solid acid, and then coats it with oil. For example, the patent number is 200310106338.7, and the name is "Acidifier for Feed Addition" ;Patent No. 20071002961.8, titled "A Microcapsule Acidifier and Its Preparation Method" and Application No. 201010525517.4, titled "Protective Feed Acidifier and Its Processing Method" and other patents. Some protection has been carried out, and the palatability has been improved to a certain extent, but the use of carrier adsorption treatment often leads to a decrease in the effective content of acid, low drug loading, and rapid absorption in the stomach, and rarely reaches the post-digestion stage such as the small intestine of animals road
