Introduction
Iodine is an essential trace mineral for all animals. It supports thyroid function, growth, reproduction, and overall health. However, ensuring that livestock receive the right amount of iodine without loss during processing or storage can be challenging. This is where Ethylene Diamine Dihydriodide (EDDI) plays a critical role.
EDDI is a stable, highly bioavailable iodine compound widely used in animal feed to improve iodine intake and support healthier livestock. As a trusted global manufacturer of iodine derivatives, Calibre Chemicals supplies high-quality EDDI that helps feed producers create safer, more consistent, and more effective nutrition solutions.
What Is Ethylene Diamine Dihydriodide (EDDI)?
EDDI is an organic iodine compound formed by combining iodine with ethylenediamine. It offers several advantages over inorganic iodine salts such as potassium iodide or calcium iodate.
Key features of EDDI:
- Highly stable during feed processing
- Excellent resistance to heat and humidity
- Very high iodine bioavailability for animals
- Low reactivity with other feed ingredients
- Easy to blend into premixes and complete feeds
Because of these advantages, EDDI has become a preferred iodine source for specialised feed applications.
Why Iodine Matters in Animal Health
All livestock including cattle, poultry, swine, goats, and sheep depend on iodine for proper metabolic and hormonal regulation.
Iodine supports:
- Healthy thyroid gland function
- Improved growth and development
- Balanced metabolism and energy utilisation
- Better reproductive performance
- Healthy skin, wool, and coat condition
- Disease resistance and immune function
Iodine deficiency can lead to goitre, reduced fertility, weak offspring, growth problems, and poor feed efficiency. Ensuring a stable supply of iodine is therefore essential for safe and productive farming.
How EDDI Contributes to Safer Animal Feed
1. Superior Bioavailability
The body absorbs iodine from EDDI more efficiently compared to some inorganic iodine sources. This ensures animals receive the right amount of iodine even when feed intakes vary.
2. Prevents Iodine Loss During Feed Processing
Traditional iodine salts may degrade due to:
-
- High temperatures
- Pelleting pressure
- Moisture
- Long storage time
EDDI remains stable through all these challenges, preserving iodine levels from manufacturing to consumption.
3. Supports Thyroid and Metabolic Health
Consistent iodine intake from EDDI helps maintain healthy thyroid hormone production, which directly impacts:
-
- Growth rate
- Milk yield
- Fertility
- Feed utilisation
This leads to stronger, healthier animals with improved productivity.
4. Helps Reduce Foot Rot in Cattle
EDDI has been used in some regions as a nutritional aid to reduce the occurrence of foot rot in cattle. By supporting immune function and tissue health, it can help strengthen natural defences against infection when included as part of an overall veterinary-guided program.
5. Enhances Reproductive Performance
Adequate iodine intake is vital for:
-
- Healthy pregnancies
- Normal development of calves and chicks
- Reducing stillbirth risk
- Supporting fertility in breeding animals
EDDI ensures iodine is absorbed quickly and efficiently, contributing to healthier offspring and stronger reproductive cycles.
6. Ensures Feed Safety and Uniformity
EDDI blends well in:
-
- Mineral premixes
- Concentrates
- Mash and pellet feed
- Liquid feed systems
This helps feed producers maintain uniform iodine levels across batches, improving consistency and safety.
Applications of EDDI in the Animal Feed Industry
1. Cattle & Dairy Nutrition
Dairy cattle have high iodine demands due to milk production. EDDI helps maintain strong metabolic function and supports calf health during pregnancy.
2. Poultry Feed
Broilers and layers benefit from EDDI’s stability in pelleted feed. The improved iodine availability supports growth, egg production, and hatchability.
3. Swine Feed
EDDI supports reproductive performance and helps maintain strong thyroid function in sows and piglets.
4. Sheep & Goat Feed
Small ruminants require precise iodine supplementation to avoid deficiency or excess. EDDI offers predictable delivery and easy mixing.
5. Veterinary and Speciality Formulations
EDDI is also used in:
-
- Liquid supplements
- Oral drenches
- Mineral blocks
- High-performance feed additives
