Problems solved by technology

However, the liquid acidifiers in the prior art generally need to be prepared with purified water or distilled water, and the pH value of the prepared acidifier stock solution is mostly less than 3, and the pH value of some acidifier stock solutions is even lower than 2, which will increase the danger when used. Moreover, the dilution and buffering capacity of acidifiers is relatively general, most of them can only be diluted 1000 times, and the pH value stability after dilution is also poor

Abstract

The invention relates to a liquid organic acid composite acidifier for livestock and a preparation method thereof. The composite acidifying agent is prepared from the following raw material components in parts by mass: 39 to 43 parts of citric acid, 16 to 40 parts of alkali, 92 to 108 parts of formic acid, 37 to 48 parts of acetic acid, 48 to 52 parts of propionic acid, 140 to 165 parts of lactic acid, 94 to 108 parts of ammonium formate, 8 to 12 parts of copper sulfate, 30 to 70 parts of phosphate and 400 to 496 parts of water. The invention also discloses a preparation method. The acidifying agent has the advantages that the acidifying agent can be prepared or diluted with tap water, the pH value is 3.8-4.0 after the acidifying agent is diluted with the tap water by 3000 times, and the acidifying agent diluted with the tap water by 1000 times, 2000 times and 3000 times has a good inhibition effect on escherichia coli and staphylococcus aureus, so that the breeding production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a liquid organic acid compound acidifier for poultry and livestock and a preparation method thereof. Background technique [0002] According to the announcement of the Ministry of Agriculture and Rural Affairs of my country, the addition of antibiotics and antibacterial drug growth promoters is prohibited in animal feed, which provides protection for the safety of animal products and people's health in our country. It is one of the key points in the research of animal nutrition and the development of animal husbandry technology. Acidifier is a green and environmentally friendly feed additive. It is an important additive to replace antibiotics. Acidifier can improve the microbial flora in the intestinal tract of animals, promote the reproduction of beneficial microorganisms, and then inhibit the growth and reproduction of harmful bacteria, thereby ensuring the health of the ...
