China reduces reliance on US soy with fermented feed amid rising costs and trade tensions
China’s pig farmers are increasingly adopting fermented feed—a mixture of local agricultural by-products fermented to improve digestibility—to cut costly soybean use amid ongoing trade tensions and soaring global commodity prices. This shift forms part of Beijing’s wider strategy to enhance food security and domestic self-reliance in agriculture.
Fermented feed transforms pig farming economics
In Taizhou, near Shanghai, pig farmer Gao Qinshan uses pools of fermented swill made from local ingredients like pumpkin vines and wine lees to partly replace soymeal in pig diets. As feed accounts for 70% of pig-rearing costs and soybean prices remain unstable due to US-China trade disputes and geopolitical unrest, such alternatives have become essential for profitability.
“Soybean prices have become very volatile,” Gao explained, reflecting a broader industry trend where oversupply and weak demand have pressured margins.
Government push accelerates adoption
In March 2025, China significantly accelerated policies encouraging diversified protein sources in livestock feed as part of a national plan to reduce soybean imports—particularly from the United States—and build domestic capacity.
Fermented feed adoption in industrial animal feed increased from 3% in 2022 to 8% in 2026, with projections reaching 15% by 2030. This could reduce China’s soybean import needs by over 6%, bolstering food security amid global disruptions.
Industry-wide supply chain mobilisation
Major companies support the transition: Muyuan Foods lowered soymeal use in pig feed from 10% to 7.3% using synthetic amino acids derived from fermented corn starch. New Hope Liuhe developed soy-free feed for poultry, and leading dairy producers Yili and Mengniu reduced soymeal in cattle feed by 20%, supported by state innovation centres.
Foreign investment is also flowing in, with Dutch firm Louis Dreyfus planning a fermented feed production line in Tianjin, highlighting China’s role at the forefront of fermentation technology.
Challenges and considerations
While cost-saving is clear, challenges remain: lack of standardised fermentation processes may compromise animal growth rates and disease resistance. Additionally, consumer demand for high-quality meat creates tension between cost-cutting and product flavour.
Analysts urge balancing feed innovation with animal health to sustain both farmers’ livelihoods and consumer preferences.
Implications for global agriculture
China’s aggressive move away from US soy has global repercussions, tightening supply chains and shifting trade flows. It illustrates how geopolitical dynamics drive agricultural innovation and market evolution at scale.
For countries like Zimbabwe, understanding such trends offers insight into opportunities to diversify feed sources, reduce import dependence, and build resilient food systems aligned with national strategies like Zimbabwe’s National Development Strategy 1 (NDS1).
Conclusion
China’s pivot to fermented feed amid trade tensions and rising soybean prices highlights the intersection of geopolitics, technology, and agriculture. The transition fosters more sustainable, cost-effective pig farming but demands careful management to preserve animal health and product quality, ultimately shaping global food security landscapes.
