Problems solved by technology

[0003] Ordinary zinc oxide has poor dispersion and is easy to decompose in the gastric acid environment. Mixing with other minerals in the feed will inevitably lead to a series of problems such as reduced stability of vitamins and reduced potency of other nutrients, which undoubtedly increases the feed formulation. The difficulty of design affects the quality of feed and increases the cost of feed
In addition, it will also cause problems such as poor feed palatability, affecting the luster of animal fur, and affecting economic benefits.

Abstract

The invention provides a production method of enteric coated nano zinc oxide particles, and belongs to the technical field of feeds and feed additives. The production method comprises the following process steps: firstly sieving a zinc oxide raw material, adding auxiliary materials, granulating, rounding and drying, heating palm oil to melt, adding a surfactant, spraying the surfactant into a dried material in a fluidized bed, coating, sieving after coating is finished, and sieving to obtain the enteric coated zinc oxide particle product. The zinc oxide particles prepared by the method disclosed by the invention ensure that zinc oxide is not destroyed by gastric acid in the stomach, is disintegrated and released after reaching the intestinal tract, and is combined with the intestinal mucosa, so that the convergence and bacteriostasis effects of zinc oxide are effectively enhanced, and the immunity of animal organisms is improved.

Description

technical field [0001] The invention belongs to the technical field of feed and feed additives, and in particular relates to an enteric-coated nano zinc oxide particle and a production method thereof. Background technique [0002] Zinc is a component of more than 40 metalloenzymes in animals, and an activator of more than 200 enzymes. It participates in the processes of nucleic acid and protein synthesis, energy metabolism, redox, cellular immunity and humoral immunity. Among them, zinc oxide can promote the rapid development of taste bud cells in the tongue mucosa. The function of regeneration and appetite enhancement, and the antibacterial and intestinal astringent effects of zinc oxide make feed manufacturers often add a large amount of high zinc to the daily feed of weaned piglets to prevent diarrhea of ​​weaned piglets. [0003] Ordinary zinc oxide has poor dispersion and is easy to decompose in the gastric acid environment. Mixing with other minerals in the feed will i...
