Lysine is an essential amino acid which is critical to animal growth. Its concentration in general animal feed is lower than required, making it the first or second limiting amino acid that is depleted. Lysine is also known for its immunity-boosting performance in hog or poultry raising feed, and when it is added to these feeds, it helps achieve nutritional balance. It provides the feed with the proper quantity of amino acids to reduce the ammonia excretions caused by an oversupply of proteins, thus benefiting the environment. As such, the lysine used by CJ CheilJedang is produced by microorganism fermentation which is a natural resource. This lysine promotes the growth of livestock, reduces the costs for the livestock industry, and conserves the environment.
