Feed Trace Elements

Potassium iodide is an ionic compound, in which iodide ion and silver ion can form a dark yellow precipitate silver iodide (see light decomposition, can be used to make high-speed photographic film), so silver nitrate can be used to test the existence of iodide ion. Iodine, as a component of thyroxine, is closely related to the basic metabolism of livestock and poultry, and participates in almost all material metabolism processes. Iodine deficiency in livestock can cause thyroid hyperplasia and hypertrophy, decrease the basic metabolic rate, and affect growth and development. It is necessary to add iodine in the feed of young livestock and livestock in iodine deficient areas. The iodine requirement of high-yield dairy cows and high-yield laying hens is increased, and iodine is also needed in their feed. The iodine in milk and eggs increased with the increase of feed iodine. It is reported that high iodine egg can reduce the cholesterol content of human body, which is beneficial to the health of patients with hypertension. In addition, during the period of animal fattening, although there is no iodine deficiency, in order to make the thyroid function of livestock and poultry exuberant, enhance the ability of anti stress, and maintain the highest production capacity, iodide is also added. Potassium iodide as an iodine source is added to the feed, which can prevent iodine deficiency, promote growth, increase the rate of egg production and reproduction, and improve the utilization rate of feed. To sum up, potassium iodide is commonly used as analytical reagent, photographic emulsifier preparation, pharmaceutical industry, as well as photographic emulsion, soap, lithography, food additives, etc.

Calcium phosphate can be used as feed additive for poultry, which can promote feed digestion, increase poultry weight, and treat rickets and rickets of livestock. It is used as anti caking agent, acidity regulator, nutritional supplement, flavoring agent, stabilizer and water retention agent in food industry. This product is also used in the manufacture of ceramics, colored glass and milk glass. It can also be used as dental adhesive, plastic stabilizer, polishing powder, syrup clarifier and chemical fertilizer. It is also used in rubber and printing and dyeing industry, and as acid making agent in medicine.

This product can be used in papermaking, printing and dyeing industries. This product is an edible pigment, which can be used for food coloring. It can also be added to poultry feed to enhance the yellow of poultry egg yolk. Lutein has the characteristics of "natural", "nutrition" and "multi-function", and can be widely used in food, health products, cosmetics, medicine and feed additives. It can be used for dietary carotene, but it has no effect of VitaminA. It can increase the pigment concentration of spots in the eyes and may improve vision.

Zinc sulfate heptahydrate is a white particle or powder with orthorhombic crystal. It is a common astringent. It will be weathered in dry air. When heated to 30 ℃, it loses one molecule of crystal water, six molecules of crystal water at 100 ℃, seven molecules of crystal water at 280 ℃, and decomposes into zinc oxide and sulfur trioxide at 767 ℃. It is soluble in water and slightly soluble in ethanol and glycerol. It is mainly used as raw materials for manufacturing zinc barium and other zinc salts, as well as important auxiliary raw materials for viscose fiber and vinylon fiber. It is also used as printing and dyeing mordant, wood and leather preservation agent, bone glue clarification and preservation agent, medical emetic and fungicide, and trace element fertilizer in agriculture.

It is a high-efficiency nitrogen and phosphorus compound fertilizer. It can be used as flame retardant for wood, paper and fabric, dispersant for fiber processing and dye industry, glaze medicine for enamel, compounding agent for fire retardant coating, extinguishing agent for match stem and candle wick, and dry powder fire extinguishing agent. It is also used in printing plate making and pharmaceutical manufacturing.It is used as bulking agent, dough regulator, yeast feed, brewing and fermentation assistant and buffer in food industry. It is also used as an animal feed additive.
