Magnesium sulfate is a compound containing magnesium, which is a small white slanted or slanted columnar crystal with no odor and a bitter taste. It is clinically used for diarrhea, cholagogue, anticonvulsant, eclampsia, tetanus, hypertension, and other diseases. However, in feed, magnesium is often used as an additive to supplement livestock.
Feed grade magnesium sulfate is used as a supplement for magnesium in feed processing. Magnesium is an indispensable factor involved in the osteogenic process and muscle contraction in livestock and poultry, and is an activator of various enzymes in the body. It plays an extremely important role in material metabolism and neural function in livestock and poultry. If the body of livestock and poultry lacks magnesium, it can lead to material metabolism and neurological dysfunction, supply imbalance, affect the growth and development of livestock and poultry, and even lead to death.
Magnesium in the animal digestive system is mainly absorbed by the anterior gastric wall in ruminants, while it is mainly absorbed by the small intestine in non ruminants. Magnesium is easily diffused and absorbed by its simple ions or chelates. The existence forms of magnesium vary, and the absorption rate of animals varies; Different types of animals have different absorption rates of magnesium; Even animals of the same species have different rates of magnesium absorption due to their age. The absorption rate of magnesium in cattle is 5% to 30%, while in pigs and poultry, the absorption rate of magnesium can generally reach 60%.
Magnesium is one of the important components of animal bones and teeth, with approximately 0.05% magnesium present in the animal body, of which about 70% is formed as phosphate or carbonate in the bones. Magnesium is one of the structural components of animal soft tissues. 30% of magnesium in animals is present in soft tissues, such as the liver, kidney, striated meat, and brain, which contain more magnesium. More than 70% of magnesium in blood is present in cells. Magnesium is directly involved in the composition of many enzymes (such as phosphatase, oxidase, peptidase, etc.) and can activate many enzymes, such as pyrophosphatase.
The use of magnesium sulfate in feed is quite eye-catching, but it should also be noted that when using magnesium containing feed additives, it should be noted that non ruminant animals require less magnesium, which is generally 0.04% to 0.06% of the total feed. Ruminant animals require more magnesium, which is generally around 0.2% of the total feed. When producing and using magnesium containing feed additives, it is necessary to mix them evenly to prevent magnesium poisoning in animals.
