For many years, ruminant nutritionists and microbiologists have been interested in manipulating the microbial ecosystem of worms to increase the production efficiency of various ruminant species.
The elimination and restriction of the use of sub-therapeutic antibiotics from the diet of ruminants have increased interest in increasing nutritional use and animal productivity, and in finding safer alternatives.
Some bacterial and fungal microorganisms, such as Directly Supplied Microbes (DFM) may be the most suitable solution. For more information about direct-fed microbials, you can click here now.

Microorganisms commonly used in DFM for ruminants can mainly be identified as lactic acid-producing bacteria (LAB), lactic acid-producing bacteria (LUB), or other types of microorganisms such as Lactobacillus, Bifidobacterium, Enterococcus, Streptococcus, Bacillus, and Prevotellabryantii, in addition to several species of fungal yeasts such as Saccharomyces and Aspergillus.
Bacterial DFM has the potential to reduce scarring and promote weight loss as well as improve feeding efficiency. Mushroom DFM can reduce harmful oxygen from the rumen, prevent excessive lactate production, improve feed digestibility, and change the fermentation pattern in the stomach.
DFM can also compete with and inhibit pathogen growth, modulate the immune system, and modulate microbial balance in the gastrointestinal tract. Increased dry matter intake, milk yield, fat correction, and milk fat content were achieved by administering DFM.
However, the response from DFM is not constant; depending on dose, timing, and frequency of feeding and strain of DFM. Nonetheless, recent studies have demonstrated a positive effect of DFM on ruminant productivity.
