Demystifying Pasture, Feed, and Dry Matter Intake (DMI) Records: Tips and Tricks to Avoid Compliance Concerns


This webinar focused on the recordkeeping requirements for dry matter intake (DMI) during the grazing season, pasture access, and feed records needed for the on-site inspection and certification. The presenters demonstrated examples of recordkeeping for organic ruminant operations and discussed how to avoid common recordkeeping pitfalls that can impact compliance.

Using examples from both small and large dairies, this webinar helps viewers:

  • Understand the organic pasture rule and how to sufficiently record the grazing season to ensure smooth audits at inspection
  • Learn how to track and calculate DMI to ensure you meet compliance with the Pasture Practice Standard
