Canada's national milk recording

Name: Canada's national milk recording (DHI) dataset: laboratory-analysed individual cow and herd milk components (fat, protein, true protein, lactose, urea), somatic cell count at cow and bulk-tank level, and derived herd indices (Herd Performance Index, Transition Management Index, Cow Ranking by Income, Selacta), fused with national genetic evaluations for all dairy breeds and supplementary lab panels (microbiological, chemical, milk fatty-acid profiles).

Type: not stated
Format: Tabular test-day records and genetic evaluation files, delivered through the MySite reports/dashboards web app, eDHI, downloadable data files and published PDF benchmark guides; bilingual (EN/FR) with PDF research/benchmark annexes alongside.
Volume: National coverage of Canadian dairy: with milk recording across the national herd, plausibly 15-20M+ cow test-day analyses per year and well over 100M cumulative component/SCC records, plus the national genetic evaluation files for all dairy breeds and supplementary lab panels. Canada's national herd runs in the low millions of dairy cows, so a multi-decade per-animal record base is implied.
Users: N/A as registered users — Lactanet operates as the sector's national data hub serving Canadian dairy farms through herd recording enrolment and breed-association membership rather than open registration; enrolment is by herd/producer under a sector framework.
History: 50 years
Update frequency: not stated
Growth: Active — 2026-dated published guides and benchmark documents, an ongoing roll-out of new phenotype tools (milk fatty-acid profile as a herd-management tool) and participation in a new international dairy-data-exchange network indicate continuous programme development.
Launched: Lactanet as a merged national entity launched ~2018-2020 (consolidating Canada's prior dairy genetics and records bodies); the milk recording dataset itself inherits a national herd-recording programme running for decades before the brand.
