Quick takeaways

The use of Aspergillus oryzae in ruminant diets significantly enhances nutrient utilization and boosts overall animal performance through improved digestion.

Incorporating Aspergillus in feed not only stabilizes rumen health by promoting beneficial microorganisms but also supports better immune function in livestock.

Deep dives

Positive Impact of Aspergillus on Rumen Microorganisms

Aspergillus in the rumen significantly enhances the growth and activity of various beneficial microorganisms, particularly cellulitic bacteria and fungi. Notably, the bacteria Ruminococcus albus and the fungi Neocallimastix frontalis show substantial increments, which can reach 200% to 300%. This remarkable increase includes crucial lactate-utilizing bacteria like Megasphaera elsdenii, which helps mitigate the risk of acute ruminal acidosis by utilizing lactate, a byproduct of fermentation. These changes lead to a more stable rumen environment, promoting overall animal health and productivity.
