feed-grade zinc oxide

Feed-grade zinc oxide is mainly used in feed as the main material of microelement additive zinc.

Application: Feed-grade zinc oxide is mainly used in feed as the main material of microelement additive zinc. And it has the follow advantages:

Firstly, Zinc needed in zinc oxide is much less than that of other zinc source, which can reduce the feed addictive cost. In same condition, zinc oxide needed equals 44% of monohydrate zinc sulphate, or 28% of heptahydrate zinc sulphate.

Secondly, zinc oxide as the dry powder zinc source has the advantages of good stability, no water, no agglomeration, no deformation, which can facilitate feed processing and storage.

Thirdly, zinc oxide can be better absorbed than that of other zinc source

Technical Specification: in conformity with HG 2792-2009
