Abstract

The invention discloses feed addictive carrying super fine cobalt and the preparing and usage method. The super fine cobalt is carried by porous mineral material, the average grain size of cobalt is smaller than100 nanometer, and the cobalt content in the porous mineral material is 0.05-0.5% by weight percent. The invention employs porous mineral material as microreactor, and adds reducer to reduce cobalt salt to cobalt. The bore diameter of porous material is uniform, and so the distribution of grain size of cobalt is narrow. The cobalt powder is characterized by low toxicity and high effective, and can be used for cow, sheep, poultry and aquatic creature, and the powder is easy to mix with feedstuff.

Description

technical field [0001] The invention relates to a cobalt supplement feed additive loaded with superfine cobalt powder and its preparation and use method, in particular to a cobalt supplement with porous mineral material loaded superfine cobalt powder and its preparation and use method. Background technique [0002] The nutritional function of Co is mainly as VB 12 Components, via VB 12 Play a role in the health of animals and their growth and development. Cobalt via VB 12 Involved in methyl transfer and sugar metabolism, its active form is methylcobalamin and 5-adenosylcobalamin, both of which are coenzymes that can demethylate methionine. In addition, Co plays an important role in the metabolism of cobalt in the body, the synthesis of hemoglobin, the development and maturation of red blood cells, and the release of mature cells. Co can treat various anemias, especially for hypochromic microcytic anemia. Co can also affect animal immune function. [0003] Since Ruminant...
