Product overview

Support the rumen environment—not one isolated output.

Rumen function reflects the daily interaction between the ration, microbes, intake, cow comfort, management and the production demands placed on the herd.

ProYeact C is based on Saccharomyces cerevisiae and is designed to support rumen function and microbial balance. It complements ration management during demanding production periods, including transition and heat stress.

ProYeact C therefore complements a complete dairy programme. It does not replace correctly balanced rations, consistent mixing and delivery, clean water, forage management, cow comfort, health planning or veterinary direction.

Rumen environment

Stability support

Supports the microbial conditions associated with a more stable rumen environment within a correctly managed ration.

Feed utilisation

Fibre-digestion context

Contributes to the conditions that support fibre digestion and nutrient use when forage, feed structure and intake work together.

Dairy resilience

Demanding-period support

Complements transition, lactation and heat-pressure programmes without replacing the nutritional and management foundations.

Production windows

One functional role. Different herd contexts.

The reason for using ProYeact C, the programme window and the expected response must be defined against the cows, ration and farm conditions.

01 · Prepare the rumen for change

Transition period

Ration adaptation, dry-matter intake, cow comfort and the shift into lactation are reviewed as one connected transition programme.

Herd context · Technical confirmation required
02 · Support consistent rumen function

Demanding lactation

The role of live yeast is considered alongside ration structure, fermentable nutrients, fibre effectiveness, intake and production objectives.

Herd context · Technical confirmation required
03 · Complement resilience planning

Heat and intake pressure

Environmental load, feeding times, water access, bunk management and ration consistency remain essential parts of the response plan.

Herd context · Technical confirmation required
Ration integration

ProYeact C is incorporated through the ration. Product handling, mixing sequence, compatibility, inclusion and programme duration require Greenagro technical guidance.

Whole-system perspective

Live yeast works inside a complete dairy system.

The product role is interpreted together with the ration, transition plan, feeding routine, water, comfort, health and herd data observed over time.

Ration foundation

Feed the intended programme

Forage quality, nutrient balance, effective fibre, moisture and ration consistency establish the context for functional support.

Daily execution

Protect intake and routine

Accurate mixing, reliable delivery, bunk management, water access and cow comfort shape the practical response.

Measured follow-up

Read the herd response

Intake, rumination, manure, milk performance, health and group-level trends guide technical review over time.

Technical selection

The product role is defined. The programme remains herd-specific.

Mixed into the total mixed ration according to Greenagro technical recommendations and the needs of the herd.

01

Herd profile

Production group, stage of lactation, intake pattern, milk performance, health context and the current condition of the cows.

02

Ration structure

Forages, concentrates, physically effective fibre, moisture, mixing sequence and the consistency of the delivered ration.

03

Programme objective

The defined production period or challenge and the practical role expected from live-yeast support within the wider plan.

04

Farm execution

Bunk management, feeding frequency, water, cow comfort, climate, records and the conditions affecting consistent daily delivery.

General information—never a complete application protocol.

Exact inclusion, handling, mixing, compatibility, programme length and use instructions are established through Greenagro technical consultation using the relevant herd, ration, health, production and farm information.
