Problems solved by technology

The reasons for molybdenum deficiency in southern and northern feed are different. The available molybdenum content in the northern soil is lower than the critical concentration of molybdenum deficiency (0.15mg / kg); Under these conditions, the uptake and utilization of molybdenum by forage plants is almost zero

Abstract

The present invention discloses a molybdenum-supplementing feed additive and its preparation method. The described feed additive is an anion-exchange resin containing exchangeable molybdic acid radical, the molybdenum content in the anion-exchange resin is (by wt%) 1.0-8.5% Its preparation method is characterized by that it utilizes the feature of that the anion-exchange resin can produce exchange action with anion, so that it can make the molybdic acid radical ions be loaded in the anion-exchange resin. Because the anion-exchange resin is a controlled slowly-releasing carrier with excellent property, said anion-exchange resin possess the controllable slowly-releasing action for loaded molybdenum, so that the absorption utilization rate of molybdenum can be greatly raised. The molybdenum-supplencenting feed additive prepared by said invention has the characteristics of low-toxicity and high-efficiency, and is easily mixed with feed, can form uniform dispersion system, and is convenient for use.

Description

technical field [0001] The invention relates to a molybdenum supplement feed additive and a preparation method thereof. Background technique [0002] Molybdenum (Mo) is one of the trace elements necessary for the growth of animals and plants, and widely exists in soil, water, air, plant and animal tissues. Molybdenum was first recognized by zoologists as a toxic element. Molybdenum poisoning can cause severe diarrhea and hair discoloration in grazing sheep, which is called "Teart" disease. Therefore, people have always regarded molybdenum as a toxic substance and have long been committed to the research on the prevention and treatment of molybdenum poisoning in animals. [0003] Molybdenum is mainly dependent on molybdenum enzymes (xanthine oxidase, aldehyde oxidase, sulfite oxidase) to participate in animal body metabolism and exert biological functions. Molybdenum-containing enzymes play a catalytic role in the basic metabolism of carbon, sulfur, and nitrogen cycles. Mo...
