Abstract

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

Description

technical field [0001] The invention relates to a magnesium-supplementing feed additive of controlled and slow-release magnesium and a preparation and use method thereof. Background technique [0002] Magnesium is a cation second only to calcium, sodium, and potassium in animals, and second only to potassium in cells. It is an important ion that regulates the balance of calcium, sodium, and potassium inside and outside cells. Some nutritional and medicinal values ​​of magnesium (especially the protective effect on the heart) have attracted widespread attention of international scholars. With the deepening of research, it is found that magnesium participates in all energy metabolism in the body, catalyzes or activates more than 300 enzyme systems, especially a series of cofactors necessary for ATPase. There are many cation binding sites on the surface of organs and biomacromolecules in the body, and their ability to bind cations depends on the following two aspects: the abil...
