Zinc Oxide (Animal Feed) Standard :
|
|
|
|
Zinc oxide(72%) is recognized as an essential micronutrient to both plants and animals.
In crop farming, zinc oxide is added to fertilizers to compensate for deficiency in zinc or for poor bio-availability resulting from the composition of the soil.
Zinc oxide is used in compound animal feeds and mineral premixes as a source for the essential element zinc.
