Zinc is a component of many enzymes, proteins, ribose, etc. in animals. It participates in the metabolism of carbohydrates and lipids. It can also catalyze the mutual conversion of pyruvate and lactic acid, promote growth, and is distributed in all tissues of the animal body. Insufficient zinc can easily cause incomplete keratosis, stunted growth and hair deterioration, and can affect animal reproduction. Feed grade zinc sulfate monohydrate is a zinc supplement for the feed industry. It is a white fluid powder with high zinc content and low impurity (lead, cadmium) content, which is superior to the safety standards for feed additives. The Chemicalbook has the functions of sterilization, bacteriostasis, deodorization and self-cleaning, which can effectively prevent diarrhea in young animals. It tastes better than ordinary zinc oxide and improves the palatability of feed. The dosage is only one-ninth of ordinary zinc oxide, which greatly reduces the cost and avoids zinc waste and environmental pollution. Uniform particles, small material diameter (20~30NM), easy to absorb, it is an ideal zinc supplement and growth promoter in animal feed, with good dispersibility and fluidity, easy to deliquesce in the air, and easy to dissolve in water , Slightly soluble in alcohol, insoluble in acetone.
