Problems solved by technology

In addition, the high-zinc diet causes most of the zinc to be discharged into the environment with the feces, causing environmental pollution. The zinc content in the soil exceeds the standard. From the perspective of the food chain, it will eventually cause harm to human health.

Abstract

The invention discloses a novel feed additive and a preparation method of the novel feed additive. The additive comprises an enteric coated nano zinc oxide particle, wherein the particle comprises a nano zinc oxide core grain, a small intestine passing coating layer, a middle-layer nano zinc oxide layer and a stomach passing coating layer from inside to outside. The additive is prepared by carrying out two times of coating by using nano zinc oxide and a coating material. The finished product is used as the feed additive to be used for a livestock and poultry feed to prevent livestock and poultry from diarrhea and accelerate the livestock and poultry to grow. The feed additive adopts the nano zinc oxide; the use amount of the nano zinc oxide is less than that of common zinc oxide and the anti-diarrhea and growth-accelerating effects are better than that of the common zinc oxide due to a specific surface effect and a special ion effect of the nano zinc oxide.

Description

technical field [0001] The invention relates to a feed additive and a preparation method of the additive. The feed additive mainly contains nanometer zinc oxide. Background technique [0002] Ordinary zinc oxide has been used as a feed additive in livestock and poultry feed for a long time, and its growth-promoting and anti-diarrhea effects have been recognized by the industry. As a new type of material, nano zinc oxide has unique surface effects and physical and chemical properties, and its use effect is better than that of ordinary zinc oxide. However, both ordinary zinc oxide and nano-zinc oxide are easily destroyed by animal stomach acid and become zinc ions when used as feed additives, thereby becoming invalid. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The negative effect of high zinc is to affect the absorption of other trace elements and reduce the utilizati...
