The U.S. animal feed industry is responding to concern over its heavy dependence on China for vitamins and amino acids, and pressing Washington to act to prevent a supply disruption from triggering a food security crisis.
A November 2025 report from the Institute for Feed Education and Research (IFEEDER) found that the U.S. relies on China for 78% of its vitamin imports and 62% of its amino acid supply used in animal feed, pet food and pharmaceuticals. Some vitamins, such as biotin, are produced exclusively in China.
