Characteristic and

function

 1. Zinc Oxide is lower cost as the feed additive. It compares with the other zinc source, the unit zinc cost is obviously low.
2. Zinc oxide is the powder. It is stabile, non- moisture, not lumping, invariability and convenient for the feed processing and the long-term storage.
3. Making zinc oxide as zinc source in feed is easy to be absorbed by the animal than the other zinc source. It can make the zinc effect to be the best.
