Abstract

A Mn-complementing forage additive containing the controlled slow releasing Mn is an active Mn contained zeolite prepared from Mn salt and natural or artificial zeolite through adsorption, ion exchange reaction, filtering, drying and pulverizing.

Description

technical field [0001] The invention relates to a manganese-supplementing feed additive of controlled and slow-release manganese and a preparation and use method thereof. Background technique [0002] Manganese plays an important nutritional role in animal organisms, and its biological functions are mainly manifested in the following aspects: [0003] (1) Components of enzymes [0004] Manganese is a component of enzymes such as arginase, proline peptidase, pyruvate carboxylase, RNA polymerase, and superoxide dismutase in the body. Manganese ions also activate a variety of enzymes, and are activators of partial hydrolases, decarboxylases, phosphorylases, carboxylases, etc. Manganese is associated with the activity of polysaccharide polymerase and galactosyltransferase. [0005] (2) Manganese and fat metabolism [0006] Manganese has a special effect of promoting fat mobilization, promoting the utilization of body fat, and has the function of resisting hepatic steatosis. ...
