The intent of feeding DFM before the beginning of rumination would be to set up and maintain stable regular intestinal germs instead of a manufacturing stimulant.
Most of those research addressing the use of direct fed microbial in ruminant production is associated with neonatal dairy calves.

In young calves , the rapid establishment to adapt to strong feed by putting the rumen and intestinal germs, as well as the exception of the enteric pathogen, is the Principal goal of the usage of DFM.
Experimentally, many germs could act as DFM however they have yet to be commercialized. One such bacteria is M. elsdenii that's employed in lactating animals.
Nevertheless, when cows have been abruptly altered from high forage diet to focus diet, M. elsdenii is frequently unable to reduce lactic acidosis. In the same way, E. faecium triumphed less probable in feedlot cattle adapted to a high grain diet.
The many states faced by recently produced calves like weaning, grip, and dehorning has an impact on the microbial atmosphere. These conditions may alter the microbiota from the negative instructions thereby reducing the operation and weight reduction.
The DFM is seldom utilized in high producing dairy cows, but its usage during early lactation might be the ideal candidate because cows are in negative energy balance with high fermentable carbohydrate that's connected with lactic acidosis.
It's been proven that DFM enhances performance in dairy cows via elevated consumption of dry things and improves the milk yield and milk contents like protein, blood glucose, and insulin concentration.
