Lysine export boom belies amino acid-soymeal substitution claims
Chinese officials claim that livestock producers are substituting amino acids for soybean meal in animal feed, reducing China's reliance on imported soybeans. A spike in China's exports of the main amino acid is inconsistent with these claims. China has built massive amounts of processing capacity to produce lysine--the most common amino acid--from corn (the main raw material). China is now the world's dominant lysine producer and exporter. Yet a November 2023 report by China's Mysteel agricultural market site said production of lysine is less than half of China's production capacity. Mysteel said China's amino acid industry suffers from serious excess capacity. At peak output in 2020 Mysteel reports that China used 11 million metric tons of corn to produce lysine and other feed additives. Since then production has slipped to 8 million metric tons in 2023 due to weak feed demand and high corn prices. This does not agree with proclamations from Chinese officials...
