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

Disclosed is a preparation method of a basic manganese chloride applicable to animal feeds. The preparation method comprises the following steps of adding ammonium chloride solution into a sealed reaction device, then slowly adding in manganese oxide while stirring, heating the reaction mixture to a reaction temperature for thermostatic reaction, and after reaction is completed, performing discharging, filtering, washing and drying processes to obtain the basic manganese chloride. The prepared basic manganese chloride has the advantages of being in low in damage to nutritious components, high in product bio-availability, low in processing cost, simple in preparation processes 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...
