Abstract

The invention relates to a preparation method of a coated acidifying agent for a feed. The preparation method comprises the following steps: firstly, adsorbing phosphoric acid; uniformly mixing silicon dioxide with phosphoric acid to completely adsorb phosphoric acid; putting a phosphoric acid adsorbate into a fluidized bed coating machine; spraying coating liquid into the coating machine by a peristaltic pump to perform coating granulation; and uniformly mixing a coated product with citric acid and fumaric acid to obtain the finished product. The acidifying agent prepared by the preparation method is a combination of organic and inorganic materials and the releasing speed of the acidifying agent can be effectively lowered; a coating film wrapping grains is a protective film so that the contact between the acidifying agent and alkaline substances in the feed, a premix and the like is reduced, and the acidifying effect of the acidifying agent is enhanced. The growth and reproduction of effective microbial communities, such as probiotics, can be facilitated to generate organic acids and other antibacterial substances, so that the pH value in gastrointestinal tracts is further reduced, and the growth of harmful bacteria is inhibited. The organic acids which are gradually released in digestive tracts also have a complexing effect and are combined with microelements in the feed, the premix and the like so as to promote the absorption in small intestinal tracts.

Description

technical field [0001] The invention relates to a method for preparing an acidulant for feed, in particular to a method for preparing a coated acidulant for feed and the prepared acidulant. Background technique [0002] Acidifier is a commonly used feed additive, which can increase the acidity of the feed. The acidifier can reduce the pH value of the animal's gastrointestinal tract, thereby improving the digestive activity of the animal's gastrointestinal tract; only when the pH value of the animal's digestive tract is stabilized at a suitable In order to maintain the normal digestive physiology of animals, if the pH value is too high, the activation of pepsinogen will be inhibited, but when the pH value is higher than 6, the pepsin will be inactivated. [0003] The existing acidulant can be combined with feed or water. After the animal eats the feed or water containing the acidulant, it can effectively improve the digestive tract environment of the animal itself, thereby me...
