Introductions:
Lysine, one of essential amino acids, is the first limiting amino acid for pigs and the second for poultry. The level of dietary L-Lysine concentration significantly influences on the growth performance and feed efficiency. Supplementing L-Lysine in dietary could balance the amino acid profile in the formula and fulfill the requirements of animals to optimize the technico-economic result of production.
properties:
Stable. Incompatible with strong oxidizing agents.l-Lysine:Needles from water, hexagonal plates from dil alc.Darkens at 210°; decomp 224.5°. Very freely sol in water;very sligtly sol in alc; practically insol in ether.
Applications:
Lysine production for animal feed is a major global industry, reaching in 2009 almost 700,000 tonnes for a market value of over €1.22 billion. Lysine is an important additive to animal feed because it is a limiting amino acid when optimizing the growth of certain animals such as pigs and chickens for the production of meat. Lysine supplementation allows for the use of lower-cost plant protein (maize, for instance, rather than soy) while maintaining high growth rates, and limiting the pollution from nitrogen excretion. In turn, however, phosphate pollution is a major environmental cost when corn is used as feed for poultry and swine.
Lysine is industrially produced by microbial fermentation, from a base mainly of sugar. Genetic engineering research is actively pursuing bacterial strains to improve the efficiency of production and allow lysine to be made from other substrates.
