Compound acidulant

Abstract

The invention relates to a compound acidulant which is particularly added into feed of pigs and fowls and belongs to the field of feed additive. The compound acidulant is prepared by the following steps: crushing and sifting anhydrous citric acid, fumaric acid and malic acid powder; placing white carbon black into a mixer primarily, spraying the white carbon black into the mixer by a lactic acid pump to lead the white carbon black to cover all lactic acid; adding the anhydrous citric acid, the fumaric acid, the malic acid and silica into the mixer for mixing later; at last, adding bacillus subtilis and xylo-oligosaccharide into the mixer to be mixed into the finished product. The compound acidulant contains organic acid instead of inorganic acid, and the organic acid can slow the releasing speed of the acidulant so as to enable the acidulant to better exert the function; the compound acidulant has lactic acid taste and good palatability so as to improve the utilization ratio of the feed; compared with the inorganic acidulant, the lactic acid type acidulant has more remarkable effect of lactic acidulant, can better improve the intestinal microflora because of containing beneficial bacterium stimulator, and has remarkable diarrhea-preventing effect, thereby being an ideal digestant of animals.

Description

technical field

[0001] The invention relates to a compound acidifier, which is specifically used for adding to pig and poultry feed, and belongs to the field of feed additives. Background technique

[0002] With the continuous deepening of research on feed and additives, people have gradually realized the negative effects of certain feed additives. In particular, the extensive use or even abuse of antibiotics as one of the feed additives has resulted in drug resistance and residues, as well as the harm to human and animal health, which has aroused the attention and worry of the majority of scientific researchers and consumers. People pay more and more attention to the research of antibiotic substitutes. Since my country's accession to WTO, in order to produce green food, break through the "green barrier" in international trade, and promote the sustainable development of feed and additive industries, we have carried out research including acid preparations, enzymes, etc. Rese...
