Zinc Sulfate Monohydrate is an essential zinc source feed additive widely used in poultry, livestock, aquaculture, and ruminant feed. Zinc is a crucial trace element required for animal growth, immune regulation, and enzyme system function. It effectively prevents zinc deficiency-related issues such as growth retardation, skin diseases, and hair loss.
Our product is produced using high-purity zinc ore, ensuring high solubility, easy absorption, and excellent bioavailability. It meets international feed additive standards and enhances animal health while improving feed efficiency, making it an ideal zinc supplement.
