Open questions, open invitations.
We tell the truth about what we know and what we don't. The questions we don't yet have rigorous answers to, we put up here — paired with active studies you can join. Free product, study reports, and stipends for participating operations.

HayRite is a young product on top of an old science lineage. The Bacillus-on-hay research the product builds on stretches back decades; the DB38 strain in HayRite was selected from that lineage and manufactured at the QUT Mackay facility (the same facility behind the H57 sister strain). The peer-reviewed work on DB38 specifically — and on HayRite-treated forage's downstream effects on milk, meat, and animal health — is exactly what we're now doing.
Most preservative brands won't put their open questions in public. We do, for two reasons:
1. Honesty is a competitive advantage. Operators who buy farm inputs are tired of being sold features that haven't been measured. Telling the truth about what's measured and what's still open earns trust where competitors lose it.
2. Farmers running real operations are the best research partners. Lab studies are useful but limited. The questions that matter — does this product reduce refusal in our cattle? does treated dairy hay move milk components? — only get real answers from real operations.
How the program works
1. Apply. Short intake form (5–10 minutes). Indicates which study and your operation basics.
2. Review. Darts research team reviews your application within 5 business days.
3. Qualifying call. 30-minute call to walk through study protocol and contract.
4. Onboarding. Study packet, materials, baseline measurements before the study window opens.
5. Study window. Active data collection — typically 6 to 12 months depending on the study.
6. Report. Full study report shared with participants. Aggregate findings published; individual farm data anonymized.
✓ Confirmed Participants own their farm-specific data. Anonymized for publication; participants get the option to be named or stay anonymous in any released materials.
