Iron supplement in feed

There are many iron supplements for feed, and the biological potency varies greatly. There are mainly ferrous sulfate, ferrous carbonate, ferrous chloride, iron phosphate, ferric citrate, iron gluconate, iron fumarate (iron fumarate). ), DL-threonine iron, methionine iron, glycine iron, and the like. Commonly used is ferrous sulfate. It is generally believed that the utilization rate of ferrous sulfate is high and the cost is low. Organic iron can also be used well by animals, and its toxicity is low. Its processing performance is better than that of ferrous sulfate, but it is expensive. At present, only a small amount is used in special cases such as young animal diet and disease treatment. Iron oxide is hardly absorbed by animals, but is used as a coloring agent for feed in certain premixed feeds, salt bricks or pet food products.

The ferrous sulfate product mainly has two kinds of ferrous sulfate containing one crystal water (FeS04·H2O) and seven crystal waters (FeS04·7H2O). 7 Water ferrous sulfate is a pale green crystal or crystalline powder, which is easy to decompose and agglomerate, and must be dried before processing. 7 Water ferrous sulfate is unstable, easily oxidized to +3 valent iron which is not easily used by animals during processing and storage, and due to its hygroscopicity and reducibility, it is easy to cause damage to certain vitamins and other components in the feed. 1 Water ferrous sulfate is an off-white powder, which is obtained by heating and dehydrating 7-water ferrous sulfate. It is easy to absorb moisture and change, has good processing performance, and has good compatibility with other components, and is widely used at home and abroad.

The newborn pig can be supplemented with iron ferrous sulfate or ferrous chloride, but the effect is not satisfactory. It is usually injected with iron. It is usually injected with 1 kind of iron-cobalt injection, 150 times for one injection, or iron dextran. l Days to 3 days old, intramuscular injection of 100 mg to 200 mg can effectively prevent iron deficiency anemia in lactating pigs. Studies have shown that pigs are given oral administration of iron dextran within 12 hours of birth. For hemoglobin synthesis, iron utilization is similar to injection.
