Key indicators for soybean meal quality in poultry nutrition | Dr Nelson Ruiz

At the 4th European Symposium on Poultry Nutrition (ESPN 2025), renowned expert Dr Nelson Ruiz shared essential findings from a study analyzing the quality of commercial soybean meal, a critical ingredient in poultry feed formulation.

Key study highlights:

• ✅ 24 commercial lots of soybean meal were analyzed
• ✅ Optimal KOH protein solubility: 80–85%
• ✅ Acceptable trypsin inhibitor levels: less than 5.5 DUI/mg

These findings help nutritionists and poultry producers:

• ✅ Select soybean meal more strategically
• ✅ Adjust digestible amino acids (lysine & arginine) based on quality
• ✅ Define cost-effective thresholds for profitability

This interview offers practical takeaways for improving feed efficiency and economic returns in poultry production.
