Digestibility

Amaferm® is research proven to increase digestibility on not only starch, but many different forage qualities and types. This increase in digestibility matters, as every 1 unit increase in NDF digestibility is associated with a .17 kg increase in dry matter intake and a .23 kg increase in milk production (Oba and Allen, 1999).

Feed is usually digested from the inside to the outside because the outside has a waxy cuticle layer that makes bacterial attachment needed for digestion difficult. This is one of the reasons why alfalfa, which may have more lignin than a grass, but which is hollow-stemmed, and breaks apart easily during the chewing process, may have a more rapid digestion than a grass which is flat and must be broken into sections for bacteria to attach. Amaferm® has been shown to accelerate both the rate and extent of fiber digestion through increased growth of Neocallimastix frontalis EB188, thus functioning like a prebiotic in stimulating the activity of the fungi and the bacteria leading to more digestion.

Multiple studies have shown that Amaferm® increased dry matter digestibility on average by 9% and NDF digestibility on average by 17.3%.

Total tract digestibility provides confidence that Amaferm® impacts digestibility in more than just the NDF component of the diet. A study conducted by Gomez-Alarcon in 1991, showed that Amaferm® increased NDF, ADF, dry matter, organic matter and crude protein digestion.

Amaferm® Impacts Dry Matter Digestibility
The extent of dry matter digestibility is a crucial determinant of the nutrients utilized by the animal.  Amaferm research has shown an average increase in dry matter digestibility of 9%. Dry matter digestibility provides confidence that Amaferm impacts digestibility in more than just the NDF component of the diet.
