    at flanks, tail head and area around vulva very
    relaxed
  • Stage 2 - Hard labor and delivery - 1/2 to 2 hr

Management to prevent scours
  • Calve in pasture different from gestation
  • Colostrum!!!
  • Move to clean cow free area
  • special pasture or hay field
  • Avoid hay rings, barns or stalls and poorly
    drained areas
  • Calf sheds only in severe environments

Management to prevent scours
  • Treat and isolate calves with scours
  • fluids electrolytes and energy, milk is OK
  • no scours for 3 days before moving back to herd
  • most antibiotics and scour cures little help
  • day 1 to 7 rota virus after that e. coli
  • vaccination of cows may help
