Ruminant nutritionists and microbiologists have been interested in controlling the microbial ecosystem of rumen for decades to increase the production efficiency of various ruminant species.
Some fungal and bacterial microorganisms such as direct-fed microbials (DFM) may be the most suitable solutions. Microorganisms commonly used as ruminants in DFM can be categorized as lactic acid using bacteria (LUB), lactic acid producing bacteria (LAB).

Together with other types of microorganisms such as Streptococcus, Enterococcus, Lactobacillus, Bifidobacterium, Bacillus, and Prevotellabryantii, as well as types of yeast fungi such as Saccharomyces and Aspergillus.
DFM bacteria have the potential to soften scars and improve weight gain and feeding efficiency. Mushroom DFM can reduce harmful oxygen from the rumen, prevent excessive lactate production, increase feed digestibility, and change gastric fermentation patterns.
DFM can also fight and inhibit bacterial growth, modulate the immune system, and regulate the balance of microbes in the digestive tract.
The main objectives of gastric microbial studies are to improve feed use, production, and animal health as well as feed safety, which can be achieved by reducing desired fermentation, reducing ruminant disease, and eliminating pathogens.
However, the DFM response is not constant. depending on the dose, timing, and frequency of feeding and the strain of DFM. However, recent research has shown a positive effect of DFM on ruminant productivity.
