【Product performance】:

• Magnesium Supplementation

Magnesium is an essential element for bone formation and muscle contraction in livestock and poultry. Adding magnesium sulfate (or Epsom salt) to feed can provide animals with various enzymes. These enzymes are involved in energy metabolism, bone synthesis, and other related behaviors.

• Neuromuscular Regulation

Feed-grade magnesium sulfate supplements can maintain normal nerve conduction and muscle function, preventing muscle tremors, twitches, and spasms caused by magnesium deficiency (such as grass twitching in ruminants).

• Digestive System Function

Magnesium sulfate powder regulates intestinal osmotic pressure, promotes gastrointestinal motility, prevents constipation, and improves feed digestibility and utilization.

• Skeletal Development

Magnesium sulfate monohydrate helps in the normal formation of bones and cartilage, reduces skeletal deformities, and improves eggshell quality in poultry.

• Reproduction and Immunity

Enhances livestock and poultry reproductive performance (increases milk and egg production), alleviates heat stress, and improves immunity and resistance.

Q1: What is the main function of feed-grade magnesium sulfate monohydrate?

A1: Feed-grade magnesium sulfate monohydrate is mainly used to supplement the nutritional needs of animals for magnesium. Magnesium is an essential trace element for animal growth and health and plays an important role in nerve conduction, bone formation, and energy metabolism.

Q2: How is feed-grade magnesium sulfate monohydrate different from other forms of magnesium additives?

A2: Feed-grade magnesium sulfate monohydrate is generally more soluble and more easily absorbed and utilized by animals than other forms of magnesium additives, such as magnesium oxide or magnesium chloride. Therefore, its use in animal feed may be more effective.

Q3: Can you provide the product specifications, COA, minimum order quantity, price, and delivery time for feed-grade magnesium sulfate monohydrate?

A3: Feed-grade magnesium sulfate monohydrate has a main content of MgO ≥ 27%, Mg ≥ 16.5%, and strictly complies with feed-grade standards for heavy metals such as arsenic, lead, and fluorine. The Polifar team can provide the latest COA, ex-factory price/FOB/CIF price, with a standard minimum order quantity of one container. We have ample stock, and the standard delivery time is 7–15 days. In case of special circumstances, details will be discussed further.

Q4: Does this product comply with national standards/EU FAMI-QS/FDA and other feed additive standards? Can you provide relevant qualification certificates?

A4: The magnesium sulfate monohydrate powder provided by Polifar strictly adheres to Chinese feed additive standards. We can provide quality inspection reports, production licenses, FAMI-QS, FDA, and other qualification documents, meeting the market access requirements for export to the EU, Southeast Asia, the Middle East, and South America.

Q5: How hygroscopic and caking-prone is magnesium sulfate monohydrate under high temperature and humidity conditions? Does it affect its use?

A5: Chinese feed-grade magnesium sulfate powder, through optimized processing, exhibits low hygroscopicity and is less prone to clumping. Under normal sealed storage conditions, it maintains good flowability. In high-temperature and high-humidity environments, enhanced moisture protection is recommended, but this will not affect normal use.

Q6: How stable is the compatibility of magnesium sulfate monohydrate with vitamins, trace elements, and amino acids in premixes?

A6: Feed additive magnesium sulfate monohydrate is stable and exhibits good compatibility with vitamins, trace elements, and amino acids. It is unlikely to react and destroy nutrients, making it suitable for widespread use in premixes and concentrates.
