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.
Stability support
Supports the microbial conditions associated with a more stable rumen environment within a correctly managed ration.
Fibre-digestion context
Contributes to the conditions that support fibre digestion and nutrient use when forage, feed structure and intake work together.
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.
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 requiredDemanding lactation
The role of live yeast is considered alongside ration structure, fermentable nutrients, fibre effectiveness, intake and production objectives.
Herd context · Technical confirmation requiredHeat 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 requiredRation 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.
Feed the intended programme
Forage quality, nutrient balance, effective fibre, moisture and ration consistency establish the context for functional support.
Protect intake and routine
Accurate mixing, reliable delivery, bunk management, water access and cow comfort shape the practical response.
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.
Request technical guidanceHerd profile
Production group, stage of lactation, intake pattern, milk performance, health context and the current condition of the cows.
Ration structure
Forages, concentrates, physically effective fibre, moisture, mixing sequence and the consistency of the delivered ration.
Programme objective
The defined production period or challenge and the practical role expected from live-yeast support within the wider plan.
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.
