Official Dairy Herd Information

Name: Official Dairy Herd Information (DHI) milk component records: laboratory analyses of individually sampled cow milk for fat, protein, other components and somatic cell count, tied to herd and animal identity, covering ~550,000 cows across ~2,000 member herds in the Northeast and Mid-Atlantic US, plus management reports derived from them. Surrounding lab lines (forage, soil, animal-health diagnostics) add feed-composition and diagnostic result sets that join to the same herds.

Dataset card

Type: not stated
Format: Tabular laboratory analyte results per sampled animal/lot with test-date and herd keys, delivered as management reports and via web apps (e.g. a forage-and-soils dashboard); reference publication and form/document archives alongside. Multimodal with written extension-style educational content.
Volume: ~6.5-6.6M individual cow milk analyses per year at monthly frequency across 550,000+ cows, and plausibly 50-100M+ test-day records cumulatively; plus forage, soil and diagnostic lab results from the co-located laboratories.
Users: ~2,000 member herds served by the DHI programme (stated on the service page), representing 550,000+ cows; the broader cooperative membership across all lab lines is larger but not published.
History: 40 years
Update frequency: not stated
Growth: Mature — an established regional DHIA and laboratory cooperative with a fixed regional footprint (Northeast/Mid-Atlantic), a stable ~2,000-herd membership and a diversified lab portfolio rather than rapid user growth.
Launched: The cooperative itself is a long-established member-owned organisation (multi-decade, mid-20th-century origins as a regional dairy processing/marketing co-op); the DHI milk-testing and record service line is a mature, long-running programme rather than a dated product launch.
