Feed grade zinc oxide, an oxide of zinc, is insoluble in water and soluble in acids and bases. It is a commonly used chemical additive. Compared with other varieties of zinc oxide, it has special requirements on the index: zinc oxide content can not be lower than 95, zinc content can not be lower than 76.3, heavy metal content lead, arsenic, cadmium can not be higher than 10 PPMs. The requirements for the production process are relatively high, and the sanitary standards of the direct method and the indirect method are not up to standard. Only the wet method can be used, and after repeated replacement and reduction, strict process control can meet the corresponding index requirements.
2. Major Features of Product:
•Compared with other zinc, zinc oxide has a significantly lower cost per unit of zinc,hich is beneficial to reduce the cost of feed additives. The amount added is equivalent to 44% of zinc sulfate monohydrate and 28% of zinc sulfate heptahydrate..
•Zinc oxide is a dry powdered zinc source with good stability in feed, no water, no agglomeration, no change, easy for feed processing and long-term storage. The effect on feed vitamins is small.
•Zinc oxide is used as a zinc source and is more easily absorbed by animals than other zinc sources.
