Compared with other similar Zinc Oxide feed grade, our Zinc Oxide feed grade has thefollowinoutstanding characteristics .
1.It is lower cost to make the feed additive with the zinc oxide. The zinc oxide compares with the other zinc source, the unit zinc cost is obviously low, favors to reduce the feed cost, the adding amount is equivalent to the monohydrate zinc sulfuric acid 44%, seven water zinc sulfuric acid 28%.
2. Zinc oxide is the powdery zinc source, stability is good in the feed, non- moisture, not lumping, invariability, convenient for the feed processing and the long-term storage.
3. To make zinc oxide as zinc source is easy to be absorbed by the animal compare with other zinc source. It can make up the zinc effect to be good.
