Milestone industry co. ltd ZnO powder feed grade is hardly soluble in water, soluble in strong alkalis and acids. It is a commonly used chemical additive. The content of zinc oxide in the index cannot be lower than 95, and the content of zinc cannot be lower than 76.3. Heavy metals The content of lead, arsenic, and cadmium cannot be greater than 10 ppm. Compared with other zinc sources, zinc oxide ZnO powder feed grade is added in an amount equivalent to 44% of zinc sulfate monohydrate and 28% of zinc sulfate heptahydrate, and the unit cost of zinc will be lower.


ZnO powder feed grade plays an important role in preventing piglet diarrhea, but the dosage of ZnO powder feed grade exceeds the physiological level. After 2 weeks of weaning, not only the growth-promoting effect is weakened, but also the growth of piglets is inhibited. At the same time, high-dose feed zinc oxide also brings environmental pollution and bacterial resistance problems.


  • After feeding high-dose ZnO powder feed grade, the content of zinc in piglet feces increased sharply. Animals can only absorb and utilize zinc that meets normal physiological needs, and most of the unabsorbed zinc is eventually excreted in the form of feces. It can be seen that if high-zinc diets are widely used, a large amount of zinc will be excreted with manure and enter the soil and accumulate, which will lead to soil zinc pollution.
  • Zinc oxide triggers bacterial resistance: Weaned piglets fed high doses of zinc oxide are susceptible to exudative dermatitis.


Therefore, many studies on the reduction of ZnO powder feed grade in piglet feed are carried out around different zinc sources and different forms of zinc oxide;

MST ZnO powder feed grade is made by indirect method. Its feed-grade zinc oxide is of high purity. It is the main important additive of animal feed and the main source of zinc in animals. It is easier to be absorbed by animals than other zinc sources, and the effect of zinc supplementation is good.
