Problems solved by technology

[0004] However, the enteric zinc oxide currently on the market still has disadvantages. For example, CN101803684A mentions that zinc oxide is coated with enteric materials. Due to the coating material, it can overcome the damage of gastric acid to zinc oxide, but this coating method is There is a problem of difficult release in intestinal juice; CN102125171A also has a problem similar to the above-mentioned release of intestinal juice; CN102318750A uses zinc oxide coated with submicron level, and the zinc oxide is treated with shielding agent three times to make the coating have good tolerance to gastric acid, and it is also resistant to intestinal The intestinal absorption has been improved to some extent, but there are still defects in the release of zinc oxide in the intestine. The existing technology cannot completely solve the problems of high-efficiency utilization of zinc oxide and environmental pollution, and there are obstacles in the promotion of the market.
The reason may be that although the enteric coating layer can dissolve in the intestinal tract, the intestinal tract of weaned piglets is not fully developed, and it is in the adaptation stage from liquid food to solid food, and the intestinal weight of piglets is only 3-5% of the body weight, the coating layer made of enteric-soluble materials cannot have a suitable time to dissolve in the intestine of piglets. Zinc oxide covered with piglets can easily cause part of the zinc oxide to be excreted with piglet manure, which will negatively affect piglet feed utilization

Abstract

The invention discloses a production method of enteric zinc oxide for feed, production raw materials comprise granular zinc oxide and an enteric coating layer material, and the mass ratio of solid content in the granular zinc oxide to solid content in the enteric coating layer material is 1: (0.05-0.2); and production raw materials of the granular zinc oxide comprise zinc oxide powder and auxiliary materials. The zinc oxide has the advantage that the utilization rate of the zinc oxide feed additive for weaned piglets can be obviously improved.

Description

technical field [0001] The invention relates to a feed additive production technology, in particular to a feed zinc oxide additive production technology. Background technique [0002] Zinc is a trace element necessary to maintain normal physiological functions and biochemical metabolism of humans and animals. It is called a "life element" because of its extensive physiological functions in the body. Zinc is a component of more than 40 metalloenzymes in the body, an activator of more than 200 enzymes, and participates in the processes of nucleic acid and protein synthesis, energy metabolism, redox, cellular immunity and humoral immunity. In addition, it has been reported that zinc can promote the rapid regeneration of tongue mucosa taste bud cells and enhance appetite. Adding zinc oxide to the diet of early weaned piglets can reduce piglet diarrhea, increase daily gain, and improve feed efficiency. Although high zinc plays a great role in preventing diarrhea in weaned pigle...
