In the process of raising livestock, poultry and aquatic products, the excessive or insufficient use of some trace elements, such as copper, iron, zinc, cobalt, manganese, iodine, selenium, calcium, phosphorus, etc., will lead to poor development or health. Therefore, feed additives can strengthen the nutritional value of feed, regulate the metabolism of the body, promote growth and development, enhance disease resistance and improve feed utilization.
According to the relevant provisions of the Regulations on the Administration of Feed and Feed Additives, the Catalogue of Feed Additives issued by the Ministry of Agriculture stipulates the usage and dosage of various nutritional supplements in feed addition. It is pointed out that the allowable varieties of feed iron mineral element additives include ferrous citrate, ferrous fumarate, ferrous lactate, ferrous sulfate, ferrous chloride, ferric chloride and ferrous carbonate.
Ferrous sulfate, as a common feed containing iron ore, is widely used in feed production. At present, ferrous sulfate heptahydrate and ferrous sulfate monohydrate are the most used in the feed industry in China. The cost of ferrous sulfate heptahydrate is low, so it is more popular in feed production, but in fact, ferrous sulfate heptahydrate is the most suitable raw material for making feed iron supplement additive.
Ferrous sulfate heptahydrate is a green crystal with poor stability.
When exposed to the air, ferrous iron will be oxidized into trivalent iron which is not easy to absorb. At this time, the color of ferrous sulfate will also change from green to brown, and ferrous sulfate heptahydrate contains seven crystal water, which is easy to absorb moisture and deliquescence, which is not conducive to storage and subsequent processing of feed. So how to avoid these shortcomings of ferrous sulfate heptahydrate?
The most effective way is to remove the free water and crystal water in ferrous sulfate heptahydrate and turn it into ferrous sulfate monohydrate with good storage performance and high iron content. Compared with ferrous sulfate heptahydrate, ferrous sulfate monohydrate has higher purity and content, and longer shelf life. Compared with ferrous sulfate heptahydrate, ferrous sulfate monohydrate has the characteristics of high iron content, good solubility, pure color, no caking, good fluidity, no crushing and no screening. Ferrous sulfate monohydrate is 1.5 times the iron content of ferrous sulfate heptahydrate. Compared with ferrous sulfate heptahydrate, it is not easy to oxidize, not easy to deteriorate, and has stable properties. It is the best ingredient choice for iron supplements in feed processing and production.
