Potassium iodide is ionic compound which iodine ions and silver ions can form yellow precipitate silver iodide (when exposes to light, it can decompose, it can be used to make high-speed photographic film), silver nitrate can be used to verify the presence of iodine ions. Iodine is ingredient of thyroxine, it is closely related to basal metabolism livestock, it participates in almost all the metabolism process, livestock iodine deficiency can cause thyroid hypertrophy, basal metabolic rate dropps, and affects growth and development. Young animals and animal feed of iodine deficiency area need add iodine, iodine requirements of high producing dairy cows, yield hens should increase, the feed also need to add iodine. Iodine of milk and egg increases with dietary iodine. According to reports, periodate eggs can reduce cholesterol levels and good for the health of patients with hypertension. In addition, during the fattening of animals, though not iodine deficiency, in order to make livestock hypothyroidism strong, enhanced anti-stress, maintain the highest production capacity, iodide is also added, potassium iodide as the iodine source is added to feed, it can prevent iodine deficiency disorders, promote growth, increase egg production rate and reproduction rate and improve feed efficiency, the amount of feed is generally a few PPM, because of its instability, iron citrate and calcium stearate (generally 10%) is usually added as protective agent to make it stable.
