For several decades, ruminant nutritionists and microbiologists have been interested in controlling the microbial ecosystem of the rumen to boost production efficiency of various ruminant species.

Removal and limitation of antibiotics sub-therapeutic utilization from ruminant diets have amplified interest in enhancing nutrient utilization and animal performance. There are many firms like feedworks that provide the direct fed microbials.

Some fungal and bacterial microorganisms as a direct-fed microbial (DFM) can be the most appropriate solutions. Microorganisms that are generally utilized in DFM such as ruminants can be categorized mainly as lactic acid using bacteria (LUB), lactic acid-producing bacteria (LAB). 

Along with other microorganism's species such as Lactobacillus, Bifidobacterium, Streptococcus, Enterococcus, Bacillus, and Prevotellabryantii, along with a fungal species of yeast like Saccharomyces and Aspergillus. 

Bacterial DFM possibly moderate rumen states, and enhance weight gain and feed efficiency. Fungal DFM can reduce damaging oxygen in the rumen, stop excess lactate production, boost feed digestibility, and change rumen fermentation patterns. 

DFM can also contend with and inhibit the growth of bacteria, immune system modulation, and regulate microbial balance in the gastrointestinal tract. 

The primary aims of rumen microbial studies would be to enhance feed usage, animal production and health, and animal food security, which could be reached by easing desirable fermentation, decreasing ruminal ailments, and excluding pathogens.
