Problems solved by technology

Due to their unstable chemical properties, inorganic trace elements are easy to chemically react with other ingredients in the feed and become forms that are not easily absorbed. Therefore, the total bioavailability of trace elements in inorganic salts is generally lower than 20%.

Abstract

The invention provides a preparation method of alkaline manganese chloride capable of being used for animal feed. The preparation method comprises the following steps: (1) adjusting the pH (Potential of Hydrogen) value of a manganese chloride solution to be 6.0 to 7.5; adding manganese; stirring for a period of time and filtering; (2) sealing filtrate filtered in the step (1) and introducing nitrogen gas or inert gas for protecting; slowly adding a strong alkaline solution while stirring; raising the temperature and carrying out constant-temperature reaction after reaching reaction temperature; (3) after reacting, adding an organic solvent or an organic solvent-water mixture into a sealed reaction system and keeping the reaction temperature in the step (2); cooling to room temprature while stirring and crystallizing; (4) filtering, washing and drying to obtain the alkaline manganese chloride. The alkaline manganese chloride prepared by the preparation method has the advantages of small damages to nutrient components, high product bioavailability, low processing cost and the like.

Description

technical field [0001] The invention belongs to the field of animal feed additives, in particular to a preparation method of manganese salt. Background technique [0002] Manganese is a component of arginase, prolinase, RNA polymerase, manganese-containing superoxide dismutase (Mn-SOD), pyruvate carboxylase, etc. Activator of enzymes, transferases, hydrolases. Manganese deficiency in animals can lead to reduced feed intake, slowed growth, reduced feed utilization, bone abnormalities, ataxia and abnormal reproductive function. [0003] At present, the manganese sources used in feed additives on the market are mainly divided into inorganic manganese and organic manganese. Inorganic manganese feed additives include MnO, MnSO 4 , MnCl 2 etc. There are differences in the availability of manganese in these compounds. MnSO 4 The bioavailability of Mn in medium is better than that of MnO and MnCO 3 , with MnCl 2 close, among them, the utilization rate of Mn in MnO is only Mn...
