Bacterial Direct Fed Microbials In Ruminant Diets

A DFM is something that has potential and live microorganisms like bacteria or yeast that are most frequently given in the feed of poultry. DFMs are also known as probiotics. 

Direct-fed microbials (DFM)  are demonstrated to boost daily gain and feed efficiency in feedlot cattle, improve milk production from dairy cows, and enhance the health and functioning of young calves.

Bacteria utilized as DFM happen to be defined as mixed cultures of live organisms, and that, when fed to animals, beneficially affect the host. More recently, but there's been a sign that bacterial DFM may have favorable effects from the rumen, like decreasing the prospect of ruminal acidosis.

In several experiments, supplementing feedlot cows with lactate-utilizing and/or lactate-producing bacteria was demonstrated to increase feed efficiency and daily gain (approximately 2.5percent ).

Probiotics or DFMs work by supplying large quantities of beneficial bacteria to the host which could occupy adhesion sites in the gastrointestinal tract and thus preventing the colonization of non-beneficial inhabitants.

The beneficial bacteria will also be able to compete with other bacterial species such as nutrients in addition to produce antimicrobial compounds that directly inhibit the growth of harmful bacteria inside the gastrointestinal tract.

In general, statistics indicate that DFM possesses the capability to reduce ruminal acidosis in feedlot cattle and milk cows, and enhance the immune response in stressed calves. More study is required to describe mode of action and thus enhance the efficacy of DFM use.
