Overview
Ferrous Fumarate is a stable, high-purity organic iron compound widely used as a nutritional supplement for both humans and animals.
It provides a highly bioavailable source of ferrous iron (Fe²⁺), essential for the synthesis of hemoglobin and red blood cells.
Unlike inorganic iron salts, it is mild to the stomach and intestines, reducing gastrointestinal irritation.
It offers high iron absorption efficiency, long shelf stability, and consistent performance in animal feed and food fortification.

Applications & Dosage
Ferrous Fumarate serves as an effective iron supplement in animal nutrition.
It helps prevent iron deficiency anemia, enhances red blood cell formation, and promotes healthy growth and feed efficiency.
It is widely used in premixes and complete feed for pigs, poultry, ruminants, and aquatic species.
Recommended Dosage
- Piglets and sows: 300–500 g/ton
- Cattle and sheep: 150–250 g/ton
- Poultry: 150–200 g/ton
- Fish, shrimp, and crab: 200–300 g/ton
Avoid direct contact with oxidants and strong acids. Mix evenly to ensure uniform distribution in feed.
Product FAQ
Q1: What is Ferrous Fumarate and how does it differ from inorganic iron supplements?
A: Ferrous Fumarate is an organic iron compound that provides divalent iron (Fe²⁺) with higher bioavailability than inorganic salts such as ferrous sulfate.
It is gentler on the digestive tract, less reactive with other nutrients, and has better stability during feed processing.
Q2: What are the main benefits of using Ferrous Fumarate in animal feed?
A: It effectively prevents iron-deficiency anemia, enhances hemoglobin synthesis, improves feed conversion ratio, and promotes healthy growth and meat coloration in livestock and poultry.
Its stable structure ensures consistent performance even in long-term storage.
Q3: What are the recommended inclusion rates for different species?
A: For piglets and sows: 300–500 g/ton; for cattle and sheep: 150–250 g/ton; for poultry: 150–200 g/ton; for fish, shrimp, and crab: 200–300 g/ton.
The actual dosage can be adjusted according to iron demand and feed formulation design.
Q4: How should Ferrous Fumarate be stored to maintain stability?
A: Keep it in the original sealed packaging, stored in a cool, dry, and ventilated area away from sunlight and moisture.
Avoid contact with strong acids, alkalis, or oxidants. Under proper storage, its shelf life reaches 24 months.
Q5: Is Ferrous Fumarate soluble in water or organic solvents?
A: It is slightly soluble in dilute acids but insoluble in water and ethanol.
This property helps maintain its stability and prevents premature oxidation, ensuring high bioavailability after ingestion.
Q6: What certificates and documents are available for this product?
A: Each batch is supplied with a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and Certificate of Origin.
Our production complies with ISO 22000 and GB/T 7300 standards for feed-grade additives.
Q7: Can Ferrous Fumarate be used together with vitamins and trace minerals?
A: Yes. It is compatible with most vitamins, amino acids, and trace minerals when mixed properly.
To avoid oxidation, it is recommended to add it during the final blending stage of feed production.
