L-Lysine
The leading amino acid
L-Lysine is the most important amino acid for monogastric species, as it is the first limiting amino acid for pigs and the second limiting amino acid for poultry.
AJINOMOTO EUROLYSINE S.A.S. produces and sells L-Lysine in two main forms:
- L-Lysine HCl 99%: a monochlorhydrate salt of L-Lysine 99%
- LLB 50: Liquid L-Lysine Base 50%
The liquid form (LLB 50), which was launched in 1994 by AJINOMOTO EUROLYSINE S.A.S. to meet the expectations of feed manufacturers, was immediately a great success with clients who appreciated its many advantages.
The main characteristics of L-Lysine HCl and LLB 50 are described below.
