Problems solved by technology

[0004] Acidifiers have a series of advantages in animal production, but there are still some problems in the process of use at present, mainly including: ordinary acidifiers are absorbed too quickly by the digestive tract of animals in animals, and most of them are absorbed in the stomach. It can seldom reach the rear digestive tract such as the small intestine of animals, and cannot fully exert antibacterial and growth-promoting effects in the rear digestive tract; ordinary acidifiers react with some alkaline active substances in the feed, causing certain damage to them; ordinary acidifiers In order to exert its due effect, it is usually necessary to add a large amount in the feed, which increases the cost of the feed

Abstract

The invention relates to enveloping acidifier and the preparation method thereof. The enveloping acidifier comprises acidifier solid microparticles and an enveloping layer on the surface of the acidifier solid microparticles, wherein the enveloping layer comprises an ethyecellulose (EC) and hydroxypropyl methyl cellulose (HPMC) composite layer and an enteric-coated polyacrylic resin layer. In theinvention, sustained-release coating material with good film forming property and the coating process are adopted, so that excessive enveloping material consumption is avoided, the weight of the acidifier solid microparticles is increased slightly, the large total effective acid of the acidifier is kept, and the acidifier has good sustained-release effect.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a coated acidifier for feed and a preparation method thereof. Background technique [0002] Acidifier is a common animal feed additive, which can reduce the acidity of the feed system, inhibit the growth of harmful bacteria in the feed and in the digestive tract of animals, maintain the balance of microbial flora in the digestive tract of animals, and improve the digestibility of feed nutrients. Reduce diarrhea in animals, especially young animals, and improve the immunity of animals. Improve animal growth performance. [0003] At present, the common acidifying agent is mainly compound acidifying agent, and its main components are various organic acids such as lactic acid, citric acid, fumaric acid, propionic acid, malic acid, sorbic acid, formic acid, etc. and phosphoric acid and other inorganic acids in a certain proportion. compounded mixture. [0004] Acidifiers hav...
