  • Species code = 0 (dairy cattle)
  • Lactation numbers 1 to 5
  • Days In Milk (DIM) 0 to 400
  • Known sire
  • Age at calving ≥ 18 months
  • Herd-year must have at least 1 occurrence of event
  • Herd-year must have at least 5 cows with lactation records
  • Herd-year incidence must be less than population mean incidence + 3 standard deviations
  • DIM requirements by event. Animals must meet this minimum DIM requirement; events must occur within this time frame
    • Milk fever = 30 DIM
    • Displaced abomasum = 60 DIM
    • Ketosis = 60 DIM
    • Mastitis = 210 DIM
    • Metritis = 90 DIM
    • Retained placenta = 10 DIM
Additional constraints for Health Data Provider credit
