L-Threonine Powder
  • Product Name: L-Threonine
  • Appearance: White Crystal Powder
  • Specification: 99% min
  • Application: Food & Feed Additives
  • CAS NO.: 72-19-5
  • Molecular Formula: C4H9NO3

L-threonine, the white crystal or crystalline powder in appearance, odorless, slightly sweet taste, is an organic compound with chemical formula C4H9NO3, optically active. As an essential amino acid, its main food sources are fermented food (cereal products), eggs, chrysanthemum, milk, peanuts, rice, carrots, leafy vegetables, papaya, alfalfa, etc.

Main Applications of L-Threonine

L-threonine amino acid can be used in medicine, chemical reagents, food fortifiers, feed additives, etc. Especially in terms of feed additives, it is often added to the feed of juvenile piglets and poultry, and it is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed.

  • As an amino acid for feed, L-threonine powder is widely used in piglet feed, breeding pig feed, broiler chicken feed, shrimp feed and eel feed, etc. Has the following characteristics:
  • Adjust the balance of amino acids in the feed to promote growth.
  • Can improve meat quality.
  • Improve the nutritional value of feed ingredients with low amino acid digestibility.
  • Production of low-protein feed helps to save protein resources.
  • It can reduce the cost of feed raw materials.
  • Reduce the nitrogen content in livestock and poultry manure and urine, the concentration and release rate of ammonia in livestock and poultry houses.

Why is threonine widely used in feed additives?

L-Threonine amino acid is usually the second or third limiting amino acid in pig feed and the third or fourth limiting amino acid in poultry feed. With the wide application of lysine and methionine synthetic products in compound feed, it has gradually become the main limiting factor affecting the production performance of livestock and poultry, especially when lysine is added to low-protein diets, threonine becomes the first limiting amino acid for pigs growth.

If we do not use threonine in the feed, the regulation of threonine in the feed can only rely on protein raw materials, and protein raw materials contain not only threonine, but also other essential and non-essential amino acids, using protein raw materials As a result of not using threonine to adjust the balance of amino acids, the balance of amino acids in the feed cannot be improved more, and the waste of a large amount of essential amino acids cannot be reduced, resulting in the failure to reduce the formulation cost of the feed. Therefore, threonine is a hurdle that must be crossed to improve the balance of amino acids, and it is a bottleneck problem that all formulators cannot avoid.

The advantage of using L-threonine is that it can reduce the waste of essential and non-essential amino acids to a certain extent, or reduce the crude protein level of the feed. Its reason is the same as that of using lysine hydrochloride. Crude protein levels can be reasonably reduced by using crystalline amino acids and animal performance may be greatly improved.
