Feed Grade Additive/Nutritional Supplement
Lysine is an amino acid essential to warm-blooded monogastric animals and humans. It has been isolated from casein in1889. For half a century L-lysine has been manufactured using bacterial fermentation of carbohydrates. Lysine was commercially introduced as a feed additive around 1960. It 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.
