PepSoyGen was developed using fermentation technology to create a functional, soy-based peptide product ideal for inclusion as a primary protein source for young animal diets. University trials have demonstrated that piglets fed PepSoyGen performed equally or better than other commonly used feed ingredients.

Since 2002 Genebiotech Co., Ltd. of Korea has manufactured PepSoyGen, employing their exclusive SMPT process (Small Molecular Peptide Technology). Genebiotech has partnered with Nutra-Flo Protein and Biotech Products to form Nutraferma, a US-based manufacturer for PepSoyGen and other value added feed ingredients.

SMPT is a fermentation process utilizing high protein soybean meal to produce low molecular weight soy peptides that are low in anti-nutritional factors

The concept behind PepSoyGen comes from a Korean tradition of fermented food products that dates back thousands of years. The fermentation process is used to improve flavoring and increase the availability of nutrients in the finished product. Many staples of the Korean diet include foods that have undergone some sort of fermentation process, such as kimchi (spiced fermented cabbage) or doenjan (fermented soybean paste).

Q&A

• What is PepSoyGen?
• PepSoyGen is a new generation peptide manufactured from the solid-state fermentation of soy for the inclusion in young animal diets, as a functional protein source.


• What are the nutritional benefits of PepSoyGen?
• Increased feed intake
• High nutrient digestibility and absorption:
• Low molecular weight peptides
• Low in anti-nutritional factors
• Microbial enzymes
• Improved growth performance:
• Optimum amino acids/peptides composition
• Organic acids
• Reduced diarrhea
• Highly stable for longer shelf life


• Why include PepSoyGen in the diets of young animals?
• PepSoyGen is vegetable protein source free of the anti-nutritional factors associated with feeding soybean meal.
• Trypsin inhibitor and the oligosaccharides stachyose and raffinose are undetectable in PepSoygen. PepSoyGen can be included in the diets of young animals, as the primary protein source.


• How does PepSoyGen compare to other protein sources in terms of animal performance?
• University research has demonstrated that piglets fed PepSoyGen perform equally with piglets fed fishmeal or dried skim milk.
• Review Technical Bulletin 46 comparing PepSoyGen to soybean meal and Technical Bulletin 47 evaluating PepSoyGen vs. fishmeal.


• What is the inclusion rate for PepSoyGen?
• Include in the diet at 3% to 8% of the complete diet.
