Zinc sulfate (ZnSO4·7H2O) is an important mineral additive that is widely used in the feed industry, especially in broiler feed, to supplement zinc, a trace element crucial to animal health and growth. Production process The main production processes of zinc sulfate include:
Ore smelting: Using zinc-containing ores such as sphalerite (ZnS), zinc is extracted through a smelting process.
Chemical reaction: Smelted zinc reacts with sulfuric acid to form zinc sulfate. Crystallization: The generated zinc sulfate solution is cooled and crystallized to obtain zinc sulfate heptahydrate (ZnSO4·7H2O). Centrifugation and drying: The crystallized zinc sulfate is separated by centrifugation and then dried to obtain the finished product.
Application in feed
1. Zinc supplement: Zinc sulfate is the main source of zinc in animal feed. Zinc plays an important role in the immune function, skin health, growth and development of animals.
2. Improve feed efficiency: An appropriate amount of zinc can improve the growth rate and feed conversion efficiency of broilers and other poultry.
3. Promote wound healing: Zinc is also very important for animal wound healing and tissue repair.
4. Comparison with other zinc sources: Inorganic zinc such as zinc oxide and zinc sulfate are lower in cost, while organic zinc such as zinc glycinate has higher biological availability.
Things to note
1. Add appropriate amounts: The amount of zinc added must be strictly controlled. Excessive amounts may cause stunted animal growth and environmental pollution.
2. Stability: The stability of zinc sulfate in feed is affected by pH value and other ingredients of feed. Pay attention to its stability in feed.
3. Biological availability: Although organic zinc additives are more expensive, their biological availability is usually higher than inorganic zinc and can be selected according to the specific needs of animals.
4. Compliance: The production and use of zinc sulfate must comply with relevant national standards to ensure product quality and safety.
