Problems solved by technology

The acidifiers currently on the market cannot quickly reach the stomach and adjust the pH value to an appropriate range, and due to the addition of too many chemical substances in the acidifier, they are not easy to decompose in the stomach and cannot achieve their own advantages

Abstract

The invention relates to a preparation method of an acidulant special for feeds. The preparation method comprises the following steps of A, performing mixing and stirring; B, performing a condensation reaction on lactic acid to form polylactic acid; C, regulating the PH value with acetic acid; D, performing adsorption and bonding; and E, performing compression, drying and disinfection. According to the preparation method disclosed by the invention, the materials are easy to obtain, the preparation method is simple, the cost is low, the PH value of the gastrointestinal tract is reduced, the enzymic activity of the alimentary tract and the digestibility of nutrient substances are improved, the structure of microorganism microbial population is regulated, the acidulant participates in metabolism in organisms, absorption is more facilitated, the immunity is enhanced, stress is alleviated, the palatability is improved, the food consumption is increased, the regulation is stable, and the acidulant has good anticorrosive and mildewproof effects, and is long in quality guarantee period, free from residues, free from drug resistance and nonhazardous.

Description

technical field [0001] The invention relates to the field of additive preparation, in particular to a preparation method of a special acidifier for feed. Background technique [0002] As a large breeding country in China, most poultry are raised on feed, and there are many kinds of additives in feed, among which acidifiers are indispensable additives. Acidifiers have become one of the important feed additives that have the same status as probiotics and enzyme preparations after antibiotics. First, a large number of experimental studies have shown that acidifiers used in animal production can replace some antibiotics, which has been widely recognized. The main role of acidifier in animal breeding is two aspects, one is to reduce the pH value of feed and animal digestive tract, to provide the most suitable digestive tract environment for animals, thereby increasing the activity of digestive enzymes, and promoting the digestion of feed nutrients by animals Second, the acidifie...
