Calcium Iodate, with CAS Number 7789-80-2, is an inorganic compound. It appears as a white to off-white crystalline powder and serves as a reliable iodine supplement in animal feed.
It is preferred over other iodine sources like potassium iodide due to its superior stability during feed processing, storage, and pelleting. Calcium Iodate is slightly soluble in water but shows better solubility in the presence of iodides or amino acids, making it effective for uniform distribution in complete feeds and premixes.
As a feed additive, it provides essential iodine for the synthesis of thyroid hormones, which regulate metabolism, growth, reproduction, and immune function in animals.
Calcium Iodate feed additive, a stable and highly bioavailable source of iodine essential for livestock, poultry, and other animals.

Key Benefits of Calcium Iodate Feed Additive
High Iodine Content and Stability:
Delivers consistent iodine levels with minimal degradation during high-temperature feed manufacturing.
Improved Bioavailability:
Supports efficient absorption and utilization by animals, helping maintain optimal thyroid hormone levels.
Prevention of Iodine Deficiency Disorders:
Reduces risks of goiter, poor growth, reproductive issues, and weak immunity in livestock and poultry.
Enhanced Productivity:
Promotes better weight gain, milk production in dairy cows, egg production and quality in laying hens, and overall animal performance.
Safe and Regulated:
Authorized for use in feed for all animal species when following maximum permitted iodine levels.
Applications and Uses in Animal Feed
Calcium Iodate is widely incorporated into animal nutrition programs across various species:
Poultry (Broilers, Layers, and Breeders)
- Supports egg iodine enrichment for human nutrition benefits.
- Improves egg production rates, shell quality, and hatchability.
- Strengthens immune response in flocks.
Livestock (Cattle, Sheep, Goats, Swine)
- Essential for dairy cows to maintain milk yield and iodine content in milk.
- Aids in growth, reproduction, and prevention of metabolic disorders.
- Critical during pregnancy and lactation phases.
General Feed Applications
- Added to complete feeds, mineral premixes, and trace mineral blends.
- Used in aquaculture and pet food formulations where iodine supplementation is required.
Frequently Asked Questions (FAQs)
Q: Why is Calcium Iodate preferred as an iodine source in animal feed?
A: It offers higher stability compared to iodide salts, better resistance to processing conditions, and consistent iodine delivery, making it ideal for premixes and pelleted feeds.
Q: Is Calcium Iodate safe for all animal species?
A: Yes, when used within authorized maximum iodine contents in complete feed, it is considered safe for poultry, livestock, and other species. Over-supplementation should be avoided.
Q: How does Calcium Iodate benefit laying hens and egg production?
A: It increases iodine content in eggs, supports thyroid function, improves egg quality parameters, and can enhance production without negative effects at recommended levels.
Q: How should Calcium Iodate be stored?
A: Store in airtight, moisture-proof containers in a cool, dry, dark place to maintain stability and prevent caking or degradation.
