Problems solved by technology

Although acidifiers play an important role in pig production, due to some characteristics of acidifiers, such as strong irritation, corrosiveness, volatile instability, easy moisture absorption, and it is difficult to avoid the influence of alkaline raw materials in feed, etc. , especially the additive properties of poor feed, which limits its application in feed

Abstract

The invention relates to a method for producing coated acidifier granules for a feed. The method comprises the following steps of: atomizing and adsorbing lactic acid; placing a proper amount of carbon black into a one-step granulator; spraying the lactic acid into the granulator for atomization and adsorption by a peristaltic pump; crushing citric acid, fumaric acid and malic acid and screening the materials with a 60-mesh sieve; mixing the materials and a lactic acid adsorbate; and adding a coating agent into a high-efficiency mixer granulator for coating and granulating to obtain the finished product. The acidifier prepared by the method is combination of organic acids, so that the releasing of the acidifier can be slowed down. The granules are coated with protective films, so that thecontact with an alkaline substance in the feed is reduced and the acidification effect of the granules is enhanced. The organic acid and other antibacterial substances can be produced by promoting the growth and mass propagation of beneficial bacteria such as lactobacillus and the like, so that the pH value in the gastrointestinal tract is further reduced and the growth of harmful bacteria is suppressed. The organic acid gradually released in the alimentary canal has a complexing effect; and the absorption in small intestine can be promoted after the organic acid is complexed with trace elements in the feed.

Description

technical field [0001] The invention relates to the technical field of feed and premix, in particular to a production method of coated acidifier granules for feed. Background technique [0002] Weaning diarrhea in piglets has always been one of the top concerns of pig producers. When piglets are weaned, due to the unsound development of the digestive tract and the insufficient activity of various digestive enzymes, especially the reduced activity of pepsin, most of the dietary protein enters the middle and rear segments of the digestive tract without any digestion, resulting in a large amount of untreated piglets. The digested and absorbed protein spoils and deteriorates, producing harmful substances and causing diarrhea; therefore, increasing the activity of pepsin and improving the digestibility of protein in the front part of the digestive tract, especially in the gastrointestinal tract, play an important role in reducing diarrhea in piglets weaned. [0003] The pepsinog...
