In monogastric animals, good-quality dietary protein is digested by host proteases and the digestion products, amino acids and small peptides, are absorbed by the host.

Protein bypassing the small intestine is no longer available for the host, but serves as a substrate for bacterial protein fermentation, also referred to as putrefaction
Putrefaction leads to production of metabolites specific to fermentation of proteins
In particular, metabolites from degradation of aromatic amino acids are known for their toxicity (indole, skatole, phenol, cresol)
Protein fermentation products are not only indicators of poor protein digestibility, but some are also toxic and carcinogenic to higher animals

Who should care?

We’ve designed this panel for nutritionists and feed additive producers. If your business involves proteinous feed materials or any of the following additives:

protein sources
Organic acids
Proteases
Prebiotics
Carbohydrases

While only some of these additives directly impact protein digestibility, they may aid in controlling protein fermentation in the lower intestine.

Check the efficacy of your solution against increased protein fermentation (putrefaction) in the lower gut!

What do we measure?

Consists of the following gas chromatography analyses:

Indole
Skatole
Cresol
Phenol
Isobutyric acid
Isovaleric acid
2-methylbutyric acid
