Nutritional Feed Supplement for Optimum Rumen Function

-Nutritional Feed Supplement for Optimum Rumen Function

Optimum rumen function is achieved when the proper nutrients that actively support the growth of rumen microflora are supplied in the feed. If the organic components to stimulate this growth are not present or are deficient, the microbial community in the animal’s gut can be thrown out of balance.

Rumen-bac is a feed supplement formulated specifically for ruminant animals, to optimize rumen function by stimulating and supporting high populations of fiber-digesting bacteria, propionic bacteria and lactate utilizers, that help improve the animals’ feed utilization, efficiency and intake.
