Our formulation provides the highest elemental zinc content at the lowest cost of ownership and is the source of choice for large scale feed makers globally. We have 11+ years of R&D experience and ISO, FAMI-QS, Halal and Kosher certifications, guaranteeing full traceability from raw material to delivery. Whether it’s improving broiler growth rates, dairy cow hoof health or piglet immunity, our product is the bioavailability reference standard that nutritionists trust across the world. Fast delivery (3-5 days for custom orders) and versatile packing (25 kg-1,000 kg) keep your production running.

Zinc is needed by more than 300 enzymes to function correctly. Your animals require it to make DNA, metabolise protein and produce immune cells.
The true magic of this product is that it totally dissolves in water. This allows mixing into premixes easily. You will not have to worry about clumping during pelleting or extrusion.
This trace element is more readily absorbed than zinc oxide. Animals better use sulphate forms, resulting in improved growth performance and lower supplementing costs per kilogram of gain.”

1. Maximum Zinc Concentration at Minimum Unit Cost
Contains 35% elemental zinc as the monohydrate. fewer powder to suit dietary requirements, fewer freight expenses and warehouse space.
2. Bioavailability Reference Standard
The product is used by nutritionists as the 100% benchmark to judge other zinc sources. Your animals absorb more, waste less in excrement.
3. Supports Immune System and Reduces Deaths
Zinc helps to stimulate T-cells and make antibodies. Diarrhoea occurrences are less in weaned piglets. Broiler flocks have developed increased tolerance to respiratory problems.
4. Enhances Skin, Hoof, and Feather Integrity
Zinc is necessary for keratin production. Dairy cows get harder hooves and are less likely to get lame. Poultry have shiny feathers, which makes market grading easier.
5. Accelerates Growth and Reproductive Performance
Zinc influences the secretion of growth hormone and cell division. Sows have bigger litter sizes. Beef cattle put on weight faster, cutting time to market.
6. Easy to Process and Heat Stable
Withstands normal pelleting temperatures of 80 to 90° C. Mixes well with other minerals and vitamins. No extra handling equipment, it simplifies your production process.
Poultry: 40-80 ppm in broiler and layer diets. It supports bone formation, immunological function, and eggshell quality.
Swine: 80-120 ppm in starter and growth rations. Diarrhoea after weaning and improves feed conversion ratios.
Ruminants: 50-100 ppm in beef and dairy feeds Boosts milk production, hoof health and breeding efficiency.
Aquaculture: Add to fish and shrimp diets at 30–60 ppm. Enhances enzyme activity and stress tolerance during handling.
Pet Food: Add to high-end dog and cat formulas. Supports cognitive function and maintains coat shine in ageing pets.
Zinc Sulfate Powder is one of the trace elements that are essential for a balanced nutrition. Under-supplementation causes poor growth and reduced immunity. Too much of the supplement can interfere with the absorption of copper and iron.

Heavy metals (Pb, As, Cd, Hg) are analysed by ICP-OES in each batch. Microbial testing has confirmed the absence of E. coli and Salmonella. We have full traceability records from raw sulphate sourcing through to final packaging.
We are ISO 22000 and GMP certified and guarantee constant particle size distribution. It avoids segregation in bulk bags and ensures homogeneity in your final feed blends.
Moisture resistant packaging (25 kg multi-wall paper bags with PE lining, 500 kg huge bags) prevents caking during sea transit. Shelf life is up to two years in dry circumstances below 25°C.


Standard Stock: Available for quick shipment. Samples and small orders, Fedex, DHL and UPS choices.
Bulk Orders: Sea freight to all major ports around the world. Urgent replenishment air freight available.
Custom Formulations: Want a certain zinc to sulphate ratio? Our R&D team provides tailor-made solutions in 3-5 days.
And technical support does not cease with delivery. Recommendations for application are given to maximise inclusion rates based on your feed matrix and desired animal performance.

Q: What is zinc sulfate used for in animal feed?
A: Essential trace mineral for enzyme function, immunity, growth, skin/hoof/feather health, reproduction, and wound healing in all animal species.
Q: What is the zinc content?
A: 35.0% Zn in monohydrate (ZnSO₄·H₂O); 22.0% Zn in heptahydrate (ZnSO₄·7H₂O). Monohydrate offers higher concentration and better stability.
Q: Is zinc sulfate better than zinc oxide?
A: Higher bioavailability than oxide. Oxide is cheaper but less soluble and absorbable. Sulfate is the reference standard for zinc bioavailability.
Q: Recommended dosage?
A: Typically 40–150 ppm of total feed, depending on species and stress level. Nutritionist guidance recommended. Do not exceed legal maximums.
Q: How to store?
A: Cool, dry place (≤25°C), tightly sealed. Hygroscopic — moisture causes caking. Shelf life: 2 years.
Q: Packaging options?
A: 25 kg bags, 50 kg drums, 500–1,000 kg big bags. Custom packaging available.
Q: Does it survive feed pelleting?
A: Yes. Heat stable under standard pelleting. Some moisture sensitivity — ensure proper drying after pelleting.
Q: Is it safe? Any side effects?
A: Safe at recommended levels. Excess zinc causes toxicity — reduced copper absorption, growth depression, anemia. Follow formulation guidelines strictly.
Q: Certifications available?
A: FAMI-QS, ISO 22000, GMP, FCC, GB/T. Halal and Kosher certificates available on request.
Q: Which animals benefit most?
A: All animals, especially fast-growing broilers, weaned piglets (preventing diarrhea), dairy cows (hoof health), and breeding stock (fertility).
