As one of the most widely used protein sources in animal feed, soybean meal (SBM) remains a cornerstone for livestock nutrition globally. With over 30 million metric tons produced annually worldwide—and China, the U.S., and Brazil leading production—the demand for high-quality SBM continues to rise. But how do producers ensure that this valuable byproduct retains its protein integrity and palatability? Let’s dive into what really matters.
On average, soybean meal contains 44–48% crude protein, making it an ideal base ingredient for poultry, swine, and aquaculture diets. However, improper processing or storage can degrade amino acid profiles—especially lysine and methionine—which directly impacts growth rates and feed conversion ratios (FCR). A study published in the Journal of Animal Science found that poorly stored SBM could lose up to 12% of its digestible protein content within just 6 weeks under humid conditions.
| Processing Step | Impact on Protein Value | Best Practice |
|---|---|---|
| Extraction Temperature | High temps (>130°C) cause Maillard reactions → reduced lysine availability | Maintain 110–125°C during solvent extraction |
| Moisture Control | >12% moisture = mold risk + nutrient loss | Dry to 8–10% before storage |
| Storage Duration | >3 months without proper aeration = up to 10% drop in CP quality | Use silo bags with oxygen barrier liners |
In Vietnam, a major aquaculture hub, a leading feed manufacturer increased tilapia growth efficiency by 17% after switching from standard SBM to a low-antinutrient, extruded version. Similarly, in Brazil, dairy farms saw improved milk yield when replacing 20% of corn with optimized SBM in rations—thanks to better amino acid balance and enhanced digestibility.
These successes highlight a growing trend: buyers aren’t just looking for “cheap protein”—they want consistent, traceable, and value-added ingredients. That’s where innovation comes in.
Recent R&D breakthroughs are turning SBM into more than just a protein source:
For B2B suppliers aiming to stand out in competitive markets like Southeast Asia, Latin America, or the Middle East, differentiating through processed, certified, and purpose-driven SBM isn’t optional—it’s essential.
