Problems solved by technology

But the current technology is not mature enough, the embedding process of zinc oxide is complicated, and the embedding rate is not high
The zinc oxide produced by different embedding materials has poor stability and is greatly affected by various environments. It reacts with hydrochloric acid in gastric juice and suffers serious losses, which makes the produced zinc oxide products have different effects.

Abstract

The invention provides zinc oxide for feed and an embedding method thereof. The method comprises the following steps: preparing a sodium alginate water solution with a mass percentage of 0.5 to 2%; adding 20 to 200 grams of nano zinc oxide for feed and carriers into the solution under stirring, evenly mixing; preparing a CaCl2 solution with a mass percentage of 2 to 4%; dropwise adding the mixture of sodium alginate, zinc oxide, and carriers into the CaCl2 solution to form microspheres, and washing and drying the microspheres to obtain the product. The zinc oxide prepared by the method mentioned above has a strong oxidizing, sterilizing, and toxin-removing performance, can effectively reduce diarrhea, prominently increases the daily gain of weaned piglets, and reduces the feed conversion ratio. Moreover, the using amount of zinc oxide is largely reduced, and thus the heavy metal pollution is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of animal feed additives, in particular to zinc oxide for feed and an embedding method thereof. Background technique [0002] Zinc oxide has a strong oxidizing and bactericidal ability, so it is usually added to piglet feed to prevent weaned piglets from diarrhea due to stress, and it also has the effect of reducing feed-to-meat ratio and changing feed remuneration. Zinc oxide in nanometer form has strong oxidative and bactericidal ability, reduces piglet diarrhea and improves feed remuneration, and is a widely used feed additive. Zinc oxide can be dissolved by strong acid and strong alkali. Therefore, zinc oxide products without any embedding treatment will be dissolved by gastric acid and lose part of their effectiveness. The loss of gastric juice will also reduce the digestive capacity of poultry and livestock, reducing the production of poultry and livestock. performance. [0003] At present, the embed...
