PUTTING PRECISION

INTO RUMEN HEALTH

Rumo-STIM is a vet-formulated fermented complementary liquid feed for cattle and weaned young ruminants.

Developed on Precision Microbes’ live liquid fermentation platform, Rumo-STIM combines quantified live Lactobacillus bacteria, postbiotic fermentation metabolites, ACTIGEN® yeast-derived functional ingredient and fermented organic herbs.

Together, these ingredients are included to support the living microbial ecosystem at the heart of ruminant digestion, helping to maintain normal rumen function, microbial balance, rumination and feed intake during periods of nutritional, physiological or management challenge.

  • Rumen microbiome balance
  • Normal rumen fermentation
  • Rumination and rumen motility
  • Feed intake and digestive function
  • Digestive resilience during nutritional challenge
Why It Matters

The rumen is a living ecosystem, not just a stomach

The rumen is not simply a stomach. It is a living fermentation ecosystem containing billions of microbes working together to convert feed into energy and nutrients for the animal.

When the rumen is functioning well, microbial fermentation produces volatile fatty acids — acetate, propionate and butyrate — which are a major energy source for cattle.

Healthy rumen function depends on stable microbial populations, adequate fibre intake, consistent feeding, rumination, saliva production and normal pH balance. These factors are tightly connected:

Microbes → Fermentation → VFAs → Rumination → Saliva → pH Balance

When this cycle comes under pressure due to dietary change, reduced intake, transition periods, transport, grouping or other management challenges, rumen function can become less efficient.

Rumo-STIM is designed to provide targeted nutritional support for the rumen environment during these key periods.

how it works

Four ways Rumo-STIM supports rumen health

1 | Supports Beneficial Microbial Activity

  • Contains quantified live Lactobacillus bacteria selected to support beneficial microbial activity within the rumen environment.
  • Fermentation metabolites, also known as postbiotics, provide nutritional support to the rumen ecosystem.
  • Organic acids, enzymes and bioactive compounds produced during the Precision Microbes fermentation process help support normal microbial balance and digestive function.

2 | Supports Efficient Fermentation

  • A stable rumen microbial population supports fibre digestion, nutrient utilisation and volatile fatty acid production.
  • ACTIGEN®, a yeast-derived functional ingredient, is included to support gut integrity, microbial balance and normal digestive function.
  • Rumo-STIM is formulated to support normal rumen fermentation during periods where feed intake, rumination or diet consistency may be under pressure.

3 | Supports the Rumen Environment

  • Fermented organic herbs provide naturally occurring plant compounds, including aromatic and polyphenolic components, within a fermented liquid feed format.
  • These ingredients are included to support the rumen environment and beneficial microbial activity.
  •  The fermented liquid format allows practical oral administration, high palatability and rapid inclusion into daily herd management routines.

4 | Supports Recovery of Rumen Function

  • Supports the rumen environment during periods of reduced intake, dietary change or management stress.
  • Supports rumination, saliva production and normal rumen pH balance.
  • Supports feed intake and digestive function as part of good nutritional and herd management.

When To Use

Built for the moments rumen health is under pressure

Fresh & Transition Cows

Nutritional support around calving, transition and periods where feed intake or rumination may be under pressure.

Reduced Feed Intake or Poor Rumination

For use when cattle require targeted nutritional support for rumen function, feed intake and rumination.

Dietary Transitions

Useful during silage changes, TMR reformulation, housing transitions, pasture changes and seasonal dietary shifts.

Beef Cattle Under Management Stress

Nutritional support around calving, transition and periods where feed intake or rumination may be under pressure.

Lush Pasture Periods

Support during periods where rumen function, fibre balance and nitrogen utilisation may come under pressure.
