Feed Grade L-Lysine - High-Purity Lysine for Animal Feed

Basic Information

Composition and Molecular Formula: The main form of feed - grade L - lysine in the market is L - lysine hydrochloride, with the molecular formula (C_{6}H_{14}N_{2}O_{2}cdot HCl) and a molecular weight of 182.65. There is also L - lysine sulfate, such as ((C_{6}H_{14}N_{2}O_{2})_{2}H_{2}SO_{4}) with a relative molecular mass of 390.4.

Properties

Physical Properties: L - lysine hydrochloride is a gray - white or light - brown powder, odorless or with a slightly special smell. It is easily soluble in water, hardly soluble in ethanol and ether, and has hygroscopicity. It is prone to caking at high temperatures.

Functions and Applications

Improving Feed Conversion Rate: It balances the amino acid composition in feed, enabling animals to efficiently utilize feed nutrients, convert them into weight gain, and reduce feed costs.

Promoting Growth: It is essential for animal growth and plays a key role in protein synthesis. Adding it to feed can increase the growth rate of animals and promote bone growth.

Enhancing Immunity: It helps maintain the normal immune function of animals, improves their resistance to diseases, and reduces the risk of breeding.

Boosting Breeding Efficiency: It can increase the lean meat rate of breeding animals and the egg - laying rate of poultry, thus improving breeding efficiency.

Quality Standards

L - Lysine Hydrochloride: Usually, the content of L - lysine and hydrochloride is 98% or so. After deducting the hydrochloride content, the actual content of L - lysine is about 78%. Its quality can be identified by physical, chemical, and quantitative detection methods. For example, it should be a white or light - brown small - grained powder without odor or with a slightly specific sour taste, and it should be completely soluble in water without sediment.

L - Lysine Sulfate 70%: The content of L - lysine (dry - basis) should be ≥ 55.0%, and other amino acids (dry - basis) should be ≥ 10.0%. The product has a pH value of 3.5 - 6.5, a drying loss of ≤ 3.0%, an ignition residue of ≤ 4.0%, and a particle size (sieve aperture diameter 1.7mm, over - sieve material) of ≤ 10.0%.

Storage and Transportation

Storage: It should be stored in a cool, dry, and well - ventilated warehouse, away from toxic, harmful, and odorous substances. The stacking height should be appropriate, and the distance from the ground and walls should be at least 10cm.

Transportation: During transportation, it should be protected from rain and direct sunlight, and should not be mixed with toxic, harmful, and corrosive substances.

Use:

l-Lysine hydrochloride is widely used as nutritional supplements in food and beverage to support immune system function due to its antibacterial and antiviral properties, to support workout recovery and muscle growth, improve energy metabolism, promote healthy cartilage and skin, and to alleviate anxiety and stress. This supplement may be combined with Vitamin C to improve resistance to the common cold.

Lysine can enhance animal appetite, improve body's resistance to disease and promote growth. Proper adding of lysine in animal grain feed can not only accelerate the growth of livestock and poultry, shorten herds period, but also greatly increase the proportion of lean meat. Besides, pork or chicken taste better by adding lysine into feed for pigs and chicken.
