Information levelGeneral product information
Product overview
Support the intestinal environment—not one isolated symptom.
Gut function reflects the interaction between microbiota, diet, water, health, management and the environment around the bird.
ProYeact B is a functional poultry product based on Saccharomyces cerevisiae boulardii. It is designed to support a balanced intestinal environment, nutrient use and flock resilience as part of a complete health and nutrition programme.
ProYeact B therefore complements a complete flock programme. It does not replace balanced nutrition, clean water, health planning, biosecurity or corrective action when a diagnosed problem requires veterinary direction.
Balanced gut context
Supports the intestinal ecosystem as one part of a wider nutrition, health and management strategy.
Nutrient-use support
Contributes to digestive efficiency when the complete feed, intake and farm conditions are working together.
Practical resilience
Helps support birds through nutritional and environmental pressure within a structured flock programme.
Delivery pathways
One functional product. Two practical routes.
The appropriate route, timing and programme length depend on the farm objective, flock conditions and the reliability of the feed or water system.
Feed application
The intended feed, manufacturing process, flock phase and programme objective are reviewed before technical recommendations are confirmed.
Feed route · Technical confirmation requiredDrinking-water application
Water quality, system hygiene, effective consumption, delivery equipment and the intended programme window are considered together.
Water route · Technical confirmation requiredRoute selection
Feed and water application are not automatically interchangeable. Product handling, compatibility, dosage and programme duration require Greenagro technical guidance.
Whole-system perspective
Functional support works inside a complete flock system.
The product role is interpreted together with the diet, health and biosecurity plan, water, housing and the flock data observed over time.
Feed the intended programme
Ingredient quality, feed form, intake and phase-specific formulation remain the foundation around functional support.
Protect the flock context
Veterinary direction, hygiene, vaccination and biosecurity address responsibilities a functional product cannot replace.
Reduce avoidable pressure
Clean water, suitable temperature, air, litter, stocking and daily management shape the bird’s response.
Technical selection
The product role is defined. The programme remains flock-specific.
Can be administered through feed or drinking water. Dosage and programme length should follow Greenagro technical guidance.
Request technical guidanceFlock profile
Species category, age, production phase, health status, recent performance and the current condition of the flock.
Programme objective
The defined nutritional or environmental challenge and the role expected from functional support within the wider plan.
Delivery system
Feed form and manufacture or water quality, hygiene, equipment and the conditions affecting reliable intake.
Management context
Diet, housing, climate, health and biosecurity plan, recent changes and the records available for follow-up.
General information—never a complete application protocol.
Exact dosage, handling, compatibility, programme length and use instructions are established through Greenagro technical consultation using the relevant flock, feed or water, health and farm information.
