Briefing
Choline Chloride, an essential organic compound and a quaternary ammonium salt, widely used as a feed additive to provide bioavailable choline
Detailed
What is Zinc Sulphate Heptahydrate?
Zinc Sulphate Heptahydrate (ZnSO₄·7H₂O) is an inorganic compound and one of the most common and cost-effective sources of bioavailable zinc. It is extensively used as a feed additive to prevent zinc deficiency and support vital biological functions in animals. Note: Its theoretical maximum zinc content is 22%, so it cannot meet a "35% min" specification. This profile describes its standard properties.
Core Features
[2-1] Composition & Purity:
Zinc sulphate heptahydrate is primarily available in feed grade with a typical zinc content of 22% min (theoretical maximum is ~22.7%).
It contains seven water molecules, which contribute to its crystalline structure but also make it hygroscopic.
Primary Use: A fundamental micronutrient supplement in animal nutrition (poultry, swine, ruminants, aquaculture).
[2-2] Physical Form:
Form: Crystalline powder or granules.
Appearance: Colorless or white crystalline solid.
Solubility: Highly soluble in water, ensuring excellent bioavailability for animals.
[2-3] Stability & Functionality:
[2-3-1] Thermal Stability: Stable at room temperature but can lose water of crystallization upon heating above 30°C, eventually converting to the monohydrate form at higher temperatures.
[2-3-2] Moisture Sensitivity: Highly hygroscopic; readily absorbs moisture from the air, leading to caking and liquefaction. Requires stringent moisture-proof packaging and dry storage conditions.
[2-3-3] Functionality in Feed
Essential Micronutrient: Serves as a crucial cofactor for numerous enzymes involved in protein synthesis, carbohydrate metabolism, and nucleic acid synthesis.
Immune Support: Strengthens the immune system, enhancing resistance to diseases.
Skin and Integrity: Vital for maintaining healthy skin, hair, hooves, and wound healing. Prevents parakeratosis in swine.
Growth and Reproduction: Supports normal growth rates, cell division, and reproductive performance.
Zinc Sulphate Heptahydrate Crystal
Key Benefits
Handling Challenges: Due to its highly hygroscopic nature, it requires careful handling and storage to prevent caking and maintain flowability.
Concentration: Lower zinc content compared to monohydrate (22% vs. 35-36%) means higher inclusion rates in feed formulations to achieve the same zinc level.
Versatility: Suitable for use in premixes and complete feeds, though its moisture sensitivity must be accounted for in formulation.

FAQ
What is the difference between Zinc Sulphate Monohydrate and Heptahydrate?
The key difference lies in their zinc content and physical properties.
Zinc Sulphate Monohydrate (ZnSO₄·H₂O): Contains a minimum of 35% zinc. It has a lower water content, is less hygroscopic (absorbs less moisture), has better flowability, and is more stable for storage and feed mixing.
Zinc Sulphate Heptahydrate (ZnSO₄·7H₂O): Contains about 22% zinc. It has a higher water content, is highly hygroscopic, prone to caking, and can require special handling and storage conditions.
For modern feed production, the monohydrate form is often preferred due to its higher concentration and superior handling characteristics.
Why is Zinc important in animal feed?
Zinc is an essential trace mineral that acts as a catalyst for numerous enzymatic reactions in the body. It is fundamental for:
Enzyme Function: Cofactor for enzymes involved in protein and carbohydrate metabolism.
Immune System: Vital for the development and function of white blood cells.
Skin and Integrity: Necessary for collagen synthesis and skin cell repair.
Growth and Reproduction: Supports cell division, DNA synthesis, and hormonal activity.
How to store Zinc Sulphate Monohydrate properly?
To maintain its quality and prevent caking:
Store in a cool, dry, and well-ventilated warehouse.
Keep packages tightly sealed and on pallets to avoid contact with damp floors or walls.
Use a first-in, first-out (FIFO) inventory management system.
Avoid storing alongside highly hygroscopic materials.
