Essential Source of Bioavailable Iodine: Potassium iodide provides an effective and easily absorbed iodine source, supporting thyroid hormone synthesis and maintaining normal metabolic functions in livestock and poultry.
Potassium iodide CAS#7681-11-0
Promotes Healthy Growth and Productivity: Supplementing feed with potassium iodide helps prevent iodine deficiency–related thyroid disorders, improving growth, development, and overall productivity, especially in young animals.
Enhances Output Quality in High-Yield Animals: It meets the increased iodine requirements of high-yielding dairy cows and laying hens, increasing iodine content in milk and eggs and supporting stable production performance.
Added Health Value of Animal Products: Iodine-enriched eggs and milk offer additional health benefits to consumers, such as potential cholesterol reduction and support for cardiovascular health, increasing product value.

Product Application of Potassium Iodide CAS#7681-11-0
Potassium iodide is an approved iodine fortifier for food use. In China, regulations specify its application in infant foods at levels of 0.3–0.6 mg/kg, and in table salt at a dosage of 30–70 mg/kg. As a key component of thyroid hormones, iodine is involved in the metabolism of all substances in livestock and poultry and plays an important role in maintaining body heat balance. It is essential for normal growth, reproduction, and lactation in animals.
Supplementing potassium iodide can enhance growth performance, support overall health, and improve productivity in livestock and poultry. Conversely, iodine deficiency may result in metabolic disorders, physiological abnormalities, thyroid enlargement, impaired nerve function, changes in fur color, and reduced feed digestion and absorption, ultimately leading to delayed growth and development.
