Animal nutrition and ingredient availability support efficient, profitable and sustainable livestock and poultry production. The livestock and poultry sectors in the United States consume approximately 257 million metric tons (MMT) of feed annually,1 reflecting the strong demand for feed ingredients and the scale of feed manufacturing. This supports the production of more than 25 MMT of red meat2 and 27 MMT of broilers in live weight,3 contributing significantly to global food supply. Animal feed in the U.S. mainly consists of corn- and soy-based ingredients, accounting for more than 80% by weight, while supplements like vitamin and mineral premixes and synthetic amino acids (AAs) represent less than 5% of total feed tonnage (Figure 1). Despite their small proportion in animal diets, these supplements are vital for animal health and production efficiency. Thus, a reliable, steady supply of vitamins and AAs is critical for feed and livestock industries.
